Description

1. Technical area

The present invention relates to systems, methods and arrangements for retrieving and storing documents, particularly in terms of storing and retrieving documents over one or more mobile computer networks with mobile clients. The invention was made especially considering the geolocation of mobile devices and their peculiarities observed, such. For example, limited connectivity, power consumption, slow data connections, or high network latency.

2. State of the art

A challenge with mobile phones, smart phones, tablet computers (or similar devices), notebooks or other mobile microchip powered devices is to use a fast and energy efficient localization method. Often, mobile devices have a GPS sensor that allows them to obtain latitude, longitude, and altitude (hereafter the longitude, latitude, altitude, and accuracy radius are called geoposition or coordinate for short). However, the GPS components consume comparatively much electrical power, which is a problem especially with the low battery power of mobile terminals. Therefore devices often use additional possibilities for geoposition determination.

US 20110128183 A1 describes a method for determining position via Wifi information. This geopositions are stored together with the unique network identifier (BSSID) of Wifis network identifier and then used to discover, due to Wifi information, an associated length and latitude.

US 7305245 B2 describes how to create and use a reference database of Wifi access points and geopositions. This database is then used to reveal the current geoposition of a client.

The openCell-ID project (http://wiki.opencellid.org/ and http://opencellid.org/) shows an example of methods for determining geoposition due to mobile radio cells.

The Mozilla Location Service Project (https://location.services.mozilla.com/) combines various positioning techniques. Here data from cell phones and Wifi information are combined and used to calculate a probable position of a client. The exact execution of the project can be found as source code (https://github.com/mozilla/ichnaea/), in which all procedures can be found as program instructions.

In simple terms, all previously referenced methods work by storing GPS positions in combination with Wifi networks and cell phones found in the GPS position environment. The stored data then serves as the basis for a location server 100 to a probable geoposition of a mobile client 110 after calculating this its surrounding wireless networks to this location server 100 has transmitted.

The advantage of the method is that no GPS module is necessary to determine the probable position of the client 110 to determine. In many cases, a server query over a mobile radio network also requires less electrical power than using a GPS module for position determination. One problem with this technique is: when the location server 100 it is not possible to use it at the time the position is to be determined. Such unavailability can therefore come from being a client 110 has no network access, which allows him the location server 100 over a computer network 130 to reach or the client 110 no reception from a required network 130 has to access the internet. Imagine, for example, a vaulted cellar, in which Wifi computer networks 130 are installed by a client 110 but the client 110 would a mobile network 130 need to get the location server 100 to reach. Thus, its position can not be determined because no GPS reception and access to the location server 100 is available.

Furthermore, limited availability, also referred to as limited usability, is often similar to unavailability, and results in similar or equal effects, further aggravating the above problems. For example, a data connection may be of poor quality, resulting in persistent disconnections (for example, if there is a problem with poor connection quality, transmitting data such as images via EDGE or GPRS often fails; Volksfesten is a data connection often despite reception no longer usable, etc.). Limited availability can also have other causes: for example, a mobile client 110 is roaming abroad, where he has a data connection but can not use it due to cost. Furthermore, a mobile client 110 have also been throttled by the wireless service provider or a Wifi is overloaded. Due to the similarity of occurring problems of unavailability and Limited availability is therefore always a limited availability as well as limited available to understand with unavailability.

Another problem arises if there is still no GPS position in connection with Wifi or cellular information. Here can be a client 110 while starting queries, it will not get coordinates by this method.

Despite the above-mentioned limitations, locating mechanisms previously described in combination with GPS sensors are often used today in systems or programs. Programs that link site-specific information to geocoordinates often work similarly 1 , There determines a mobile client 110 the wifi and mobile stations and then sends them over an available and connected computer network 130 to a server 100 , This now calculates a single geoposition and a probable radius in which the client 110 stays 140 , The client 110 then uses this geo-information 140 and then links this with other data that he stores with a transmission to another server in a common database 120 , This approach inherits the aforementioned problems. For example, in the vaulted cellar described above, it is unlikely that storage of documents with geographic coordinates is possible. This results in another problem in the application of mobile data reception: the fact that mobile clients often in slow mobile networks, such. B. EDGE networks are logged, the query for the current geoposition in a location server 100 take a long time due to network latency. As long as the client 110 but no coordinates from the location server 100 However, this is without position and can perform neither queries nor stores in the area of the current position.

In summary, the problems of the prior art are therefore as follows A location via GPS is often possible only in the open air, which costs a lot of electrical power. A localization via Wifi networks and mobile radio cells is only possible with a data connection and can also be very unfavorable due to long latencies in mobile networks.

Another problem is the abstraction of a client to his geoposition. This being a location server 140 only one single geoposition will be used, only those will be used in further processing steps. In short: Documents are only assigned longitude, latitude in a database and all other information is lost. This abstraction then has the consequence that information such. B. the connected network are lost and this z. B. can no longer be used to z. B. restrict the visibility of data.

Furthermore, it is no longer possible to differentiate coordinates that were determined on the basis of mobile radio cell information, which were determined by a Wifi, since both are mapped to only one coordinate. However, a distinction would be extremely helpful since mobile cell information marks larger places than wifis (due to range). Another example of restrictions is the lost information of the mobile network operator. If information is stored in a database only with individual coordinates, it is no longer possible to make visibility restrictions due to the mobile service provider.

Also, the use of a single geo-coordinate leads to further restrictions. If the documents associated with a geo-coordinate are sorted by relevance, this relevance can only correspond to a sort by distance, since no further information is available.

Another problem is the geographical shift of Wifi access points (for example, after a move, a Wifi is suddenly available several hundred kilometers from the old location). Current localization mechanisms are aware of various mechanisms to address such cases. a.) Filtering: The cell is considered a mobile hotspot (a mobile network of a mobile client (tethering)) and disregarded or b.) The cell is considered to be relocated and is associated with a new geoposition and a database update is performed. However, this leads to the problem that in the case of a move all geo-information made at the old site is still associated with it only and not available to the new location of the wifi.

3. Summary of the invention

1.

The present invention solves the problems described above. In one embodiment according to claim 1, the invention comprises: a.) A functional informationable database 200 , which has at least one means for data storage, which makes it possible to associate at least one document with one or more radio information 230 ; b.) At least one query 240 at least one mobile client 110 , where the query 240 contains at least one radio information; c.) At least one means for comparison, which makes it possible, at least one radio information of a query 240 with at least one radio information of func-formational database 200 to compare and which of such a comparison at least one result set 220 calculated.

Thus, the present invention provides a system, method, and arrangement that not only allows longitude and latitude to be associated with documents, but can now include multiple information from and about radio cells, and other (wireless) networks or sensor technology and software Fields are saved and queried. This allows for matching documents and associated radio information 230 due to wireless networks directly (see also 2 ).

Often, the words information, information or information about are used in this application. In this case, information is to be equated with the word date or data. It is used, however, because it describes the facts better and easier to understand. A date specifies a storable feature such. As a number, a string or a document that can be stored in one or more storage units or memory. Classically, a date is z. For example, a cell of a table in a record. An "information about" is thus a date which contains information about data or the data itself. For example, information about the identification of a Wifi network may be the BSSID and / or SSID or the like, but also a hash value of the BSSID and / or the SSID. Such "information about" can be obtained through calculations, rules or the enrichment of the normal information with data from other sources.

A result set 220 can z. By one or more documents associated with radio information 230 or a document similar or equal to the query document 240 be represented. Furthermore, other representations of the result set are possible, such. B. Parts or extensions of the previously specified documents. In addition, a result set 220 contain more information or z. For example, it may be a list of documents associated with radio information 230 are. However, this is only to be understood as a particularly advantageous example since result sets of queries are known in the prior art (especially in the area of databases). Therefore, this invention, of course, can use these known mechanisms to process result sets and thus the result set described above 220 to expand or shrink.

Thus, there is an improvement by calculating a result set 220 where such result set 220 not, as known in the art, only one result, as a geo-coordinate may contain as a singular datum, but multiple documents or references to them may be present in a result set. These improvements therefore overcome the limitations of the prior art, and it is possible to query and store in a data-aware database 200 directly after uncovering surrounding radio information. This saves waiting for network latency geolocalizations from a location server 100 and data can be stored and queried faster.

Another advantage that results from this approach is the fact that not necessarily a location server 100 must be achievable. Much more can a mobile client 110 now operate independently of such a server and directly documents with wireless information as queries or storage 210 to the func-formative database 200 send.

The radio information can occur in many ways and in a plurality. For example, radio information is data about the physical network addresses of Wifi modules, identifiers of base stations, data about the connection of the various network subscribers as well as the frequency or the reception strength (decibels). Network users can use stationary routers as well as other mobile computer networks 130 or clients 110 regardless of whether these ad hoc computer networks 130 offer or act as an access point. Radio information can be collected by z. For example, searches for networks and the feedback from computer networks can be started 130 then be used as radio information. It is also possible already existing connections of a client 110 read out or sensors, such. B. read out for the surrounding magnetic field. Of course, it is also possible that wireless information by satellite data or calculations on these, such. GPS or the like, and even coordinates are part of the radio information. Even the coordinates of a location server 100 may optionally belong to the radio information, even if coordinates are not necessarily necessary for the operation of the invention. Also, the radio information can be enriched or replaced by normalization and adjustment algorithms. In addition, it is possible to improve or consolidate the radio information through multiple searches performed.

Another example of such radio information is data from mobile radio base stations, such as their signal strength, neighboring base stations, providers, connection types (eg UMTS, GSM, LTE), speed or any other data that by reading out values in the client 110 can be determined. Also, Bluetooth, NFC or other similar data that relate to the couplings or detections of devices a client 110 can be part of the radio information. Furthermore, radio information may also contain information about magnetic fields. For example, earth magnetic field measurements may be part of the radio information. Such measurements can be normalized or present in the readout format of the sensor or specified by repeated measurements. In general, radio information is therefore synonymous with the word radio data, radio scan data, Funkanalysedaten or surrounding network scan result or the plural radio information equate, since this describes the same facts Multiple information collected in a record from sensors or programming interfaces of a client 110 mostly based on wireless networks near a client 110 Respectively. This radio information represents a feature vector / matrix / record / descriptor / fingerprint that can be used for (similarity) comparison (s) with further radio information. In particular, the radio information from two or more clients 110 to compare. Radio information can be represented and processed as / by documents.

Of course, the wireless information may also contain information about other sensors, such. B. the current orientation of the device. Important here is the plurality of data rather than just a single geoposition, and not limited to one source. All data can additionally be enriched by a time date in order to have an indicator of the actuality of the data available at each subsequent process.

Due to this plurality of radio information documents can now be stored not only specifically to a singular geoposition, but documents can now be associated with the entirety of the radio information in connection and stored.

This triggers z. As the restriction in the prior art in a move, in which the data remain at the old geoposition. Now there are queries with radio information 240 are possible, the associated data can now be found at any place where the associated wireless network from a mobile client 110 is recognizable. When a Wifi module has been transported to a new location, the data associated with the wireless network is now found. Since this is the same network as before, so also the existing data of another geoposition are found.

Documents, which then together with the radio information 230 in the combined radio information database 200 are not only technical documents, such. As coordinates dar. Rather, they can represent a variety of semantic content. For example, this may be user-generated information, e.g. B. information about one or more places or attractions near the village included. Also users or machine-generated classifications, such as ratings are possible. This results in the advantage that by wireless information such documents can be stored or determined directly in relation to surrounding wireless networks without the compulsion of a location server 100 by a client 110 to use. This saves z. B. the determination of a geo position by a request to a location server 100 , which is particularly advantageous in slow networks.

Documents are not just documents in the classical sense. Much more documents can also be active resources, such as a web server or multiple web servers from which then the information is loaded. The term document also refers to several systems or also via computer networks 130 coupled systems. The term document is therefore a collective term for all possible outputs of a database or even a collection of user-generated data. A document can, for. B. dynamically generated from a database, which is why a database in the context of the present invention is to be regarded as a source or combination of sources or source systems from which data can be requested, written and / or changed. A document is thus a logical unit, a partition, component and / or subdivision, and therefore also applies to parts of documents. Embodiments of the present invention can use the structure information of the database in order to improve and / or accelerate access to the database or documents occurring therein. By way of example, the following data and associated systems or systems can serve as database and thus as documents: Hypertext documents, Word documents, e-mails, web servers, program code such as classes or objects or also other constructs which occur during programming or from compiled source code generated therefrom , API calls or return values, access to program parts, business objects, such as: For example, documents, master data, application servers, SAP systems, data warehouses, text documents, images, audio files, social networks, videos, blogs, Twitter, mobile devices such as mobile phones, peer-to-peer networks, input devices, file systems, databases , Search engines, servers, reuters, machines, sensors, test systems, Debuggers, people and / or automobiles. Unless the present invention is in a computer network 130 is used, this network and its participants can take the role of the database, on the Internet z. The Internet network itself, peer-to-peer networks, web servers, web pages, stationary clients, mobile clients 110 (eg mobile phones, notebooks, PDAs, etc.) and other actors. A web page identifies a document that is accessible via the Internet, and may include various content that occurs there, such. For hypertext documents, videos, images and other documents that may contain hyperlinks. The term website can also stand for several documents, eg. For example, all or part of the pages under a particular domain. Thus, the term website is also a collective term for what is commonly called website or website, ie a collective term for an entire website, eg. B. an appearance of a company, an organization, a private person, an association, an interest group or for a specific purpose, eg. B. sale, trade, information, discussion, exchange, pleasure, search, mediation etc. Such an Internet site can be transmitted via various protocols, eg. TCP / IP, UDP, HTTP, HTTPS, FTP, POP3, SMTP and other protocols used for communication in computer networks 130 be used.

In addition, the invention, of course, also interact directly with one or more systems together. For example, this part of a system or a system may also be a part of it. This allows seamless integration with other systems. This results in a particularly advantageous distributability, such as in a computer network 130 over several servers.

A computer network 130 For the purposes of this invention, it always represents a possible plural of networks and is not limited to just one network. Rather, different computer networks 130 as a commonality as a computer network 130 can be referred to or even computer networks 130 that interact with computer networks other than computer networks 130 be designated. Because of this, the term "computer tools" is used throughout this document 130 and computer network 130 to be considered equivalent. Often, in the previous history and in the further referred to mobile network and the like when referring to the connection data. Of course, mobile networks also provide computer networks 130 In general, the term network in this application is termed computer network 130 equate. Often, however, the number becomes 130 the term network or computer network 130 not set, because it is not directly related to an important fact of the figures, to increase the readability.

Thus, for example, documents and radio information and the func-formational database 200 not only be stored purely in a document base, but the location could be changed based on the radio information, which would allow for a distributed and fail-safe system and arrangement. It would also be possible for a client 110 another client 110 as a functional informationable database 200 used and a networked, fail-safe system purely from clients 110 is built.

Of course it is also possible, the result set and associated documents as well as optionally their radio information on at least one computer network 130 to a client 110 transferred to.

For the purposes of this invention is a client 110 mainly to mobile clients 110 However, it can always be that it is not necessarily a mobile client 110 have to be. Every other client 110 Also, a server could, in different embodiments, each have the role of the client 110 taking. Also could be a client 110 also a variety of clients 110 be, the z. By computer network 130 connected to each other. As this invention mainly addresses individual mobile clients 110 and whose interaction relates to mobile clients 110 special advantages over other clients 110 offer, this application is to be seen with a main focus on this application. It should be noted, however, that clients but also other clients 110 or a variety of other clients 110 or several mobile clients 110 could be.

Second

In a further aspect of the invention, the means for determining the result set 220 at least make a relevance classification of documents. This makes it particularly advantageous to determine the relevance of documents with respect to one or more wireless information.

This data-processing step of the relevance classification is particularly useful because documents can also be filtered based on radio information via a relevance. For example, it is possible to have documents and related radio information with data about the connectivity to a particular radio network in the radio-aware database 200 save. For a query 240 and a comparison (example of a comparison in 5 ) can then at the Relevance classification to be noted, whether in the query 240 sent wireless information of a client 110 from a connectivity to the same wireless network, like an association 230 in the func-formational database. This is useful in wifi networks, because of the connection to a wifi network, data for clients 110 can be filtered if it has not connected to the Wifi network. Thus, the relevance classification also serves for filtering and can be used to implement security functions. The same, previously described procedure for Wifi networks, can also be adapted to mobile networks. (Easier to understand and expressed as a specific embodiment of the invention.) Is a client 110 connected to the same wifi as the dataset in the radio-aware database 230 ? If not, then the records are filtered ")

Third

Examples of such data used for relevance classification are found in another embodiment of the invention. Here, the signal strength and / or the availability of one or more Wifis or mobile networks, used for relevance classification. Availability here means which computer networks 130 are within range and can be found during a search. Also, connection properties such as access authorization to the network for relevance classification may be used. Finally, the possibility also results in the identification of the network, such. For example, the name of the network (eg BSSID or SSID for Wifi and / or the mobile radio cell IDs of the associated mobile radio masts of the mobile radio network) may be used for relevance classification.

In the prior art, a relevance classification is currently possible only due to geographical distance. The plurality of radio information provides the advantage of being able to use a variety of data except the distance for relevance classification of the invention. It is also possible different networks, such. B. mobile networks and wifis to treat differently, which is a conventional location server 100 is no longer possible because it abstracts to a geoposition and not the way it was determined. This shows the problem of information loss when using a conventional location server 100 which no longer allows such advanced use cases by its abstraction on geopositions.

4th

Another embodiment of the invention specifies the case that multiple mobile clients 110 with a functional information-capable database 200 to interact. Here can be a first mobile client 110 Generate documents and wireless information and another mobile client 110 can retrieve these and / or change and expand.

5th

The invention can be particularly advantageous in a further embodiment with an improvement of the radio information by further mobile clients 110 to use. Here you can see the radio information and documents of a client 110 that are in the information-capable database 200 stored by at least one second client 110 be enriched. For example, a first client 110 stores documents and associates them with radio information from the surrounding wifis, as well as the radio masts of its mobile service provider (See eg Data structure 230 ). A second client 110 Connected to another provider using other radio masts, the first client's documents and radio information are covered 110 when he is within range of the same wifis. Because of this finding, the second client submits 110 then radio information, the mobile radio cells known to it contain to the funkinformationsfähige database 200 which are then used to the mobile phones of the first client 110 with the mobile phones of the second client 110 to enrich. By doing so, it is possible for more clients 110 then also be able to uncover these documents. In one embodiment of the invention, this enrichment is through the transmission of a data structure such as 230 or 240 a client 110 possible. This can be done by an explicit instruction and transmission by a client 110 to be started. Furthermore, the enrichment can also be started implicitly: For example, a client transmits 110 a query 240 or other information like 230 , which then automatically from a funkinformationsfähigen database 200 used for enrichment without the client 110 explicitly arranges the enrichment. For example, a wireless information-capable database 200 when receiving one or more queries 240 or one or more documents associated with radio information 230 Automatically search for similar datasets using comparisons to automatically enrich or aggregate them.

Furthermore, this case can be used to z. B. Geopositionen submit. You can imagine that a first client 110 does not know its geoposition and still has documents and radio information ( 230 ) stores (save in 200 ) - (total section 600 / 610 ). A second client 110 who at least receives a Wifi network ( 620 ), which is the first client 110 can then transmit the radio information of the first client 110 improve ( 630 ).

6th

In a further embodiment, the radio information is additionally displayed for display on at least one client 110 used. For example, the wireless information about connectivity to different networks may be used to help the client 110 indicate whether a document refers to the currently used Wifi or the same mobile radio cell. This can be characterized for example by a coloring of the documents, but also by presenting a distance indicator, such. B. as a bar or percentage.

7th

Particularly advantageously, the invention can also be used to transmissions of documents and wireless information from clients 110 also at a later date ( 700 / 830 ), which is shown in a further aspect of the invention. For example, a client 110 examine its environment for radio information and associate documents locally with this radio information 230 , A transfer to another func-formative database 200 can be done later. This allows a client 110 does not need to know his geoposition, no online connection is necessary, and despite this, documents related to radio information 230 , locally in a functional information database 200 get saved. This ability is particularly advantageous to combine with a later enrichment of the radio information, since thus radio information (such as GPS coordinates or mobile radio cells) can be maintained by other clients or third-party systems, if the data of the first client 110 ultimately to another func-formational database 200 be transmitted. This is a particular advantage over traditional systems as a client 110 Thus, it is not dependent on a mobile radio connection, GPS signal or the like and thus the system can also deal with network failures particularly advantageous and storage with radio information can almost always be done.

8th.

The present invention further relates to a method for the retrieval and storage of documents, in particular for the storage and retrieval via at least one mobile computer network 130 with mobile clients 110 , wherein the method comprises at least the following steps: a.) At least one association and storage of at least one radio information with at least one associated document ( 230 ) in at least one functional information-capable database ( 200 ) (Step 300 ); b.) At least one query ( 240 ) at least one mobile client ( 110 ) of the functional information-capable database ( 200 ) with at least one radio information (step 310 ); c.) comparison of one or more radio information of a query ( 240 ) with at least one previously stored association of radio information and document ( 230 ) (Step 320 ); d.) determining at least one result set ( 220 ) of radio information and / or documents due to the prior comparison (step 330 )

9th

Another embodiment of the method includes the following steps: a.) Specifying or creating at least one document on at least one mobile client ( 110 ) (Step 800 ); b.) Receiving at least one radio information or the use / reading of at least one radio information on at least one mobile client ( 110 ) (Step 810 ) and association of the in a. mentioned document with the radio information and storage of this association in at least one local memory on at least one client ( 110 ) (Step 820 ); c.) Transmission (step 830 ) at least one in b. stored information of at least one client ( 110 ) via at least one computer network ( 130 ), which at the time of acquisition of the radio information or the specification or creation of the document in step a. or the filing of the document in the local memory in step b. was unavailable or restrictedly usable.

10th

Finally, the present invention provides a computer program having instructions to perform each method described herein or to represent one of the described arrangements or systems individually or in combination by a computer program.

5. Detailed description of preferred embodiments

Hereinafter, preferred embodiments of the invention are disclosed. These embodiments serve as an example to increase understanding and are therefore to be understood as exemplary and exemplary embodiments that may be combined in all possible combinations of the various embodiments. By means of figures and examples, we will clearly show that an expert familiar with the prior art can use this description to implement the embodiments of the invention having the features defined in the claims.

Fig. 2.

2 shows an embodiment of the invention. A client 110 interacts 210 with the func-formational database 200 , In this database 200 are documents associated with radio information 230 , An example of such a func-formative database 200 can be realized is a table in a database in which, in one or more columns, the documents are stored and in one or more other columns and / or tables, the wireless information is stored.

An interaction of a client 110 can query or save documents in the functional information database 200 be. A query and also a storage can contain radio information and normal documents ( 240 ) and thus documents with radio information in the funkinformationsfähige database 200 Write this or by radio information and documents 240 query appropriate records. The query / storage documents 240 can all data from radio information and associated documents 230 contained (ie every date of 230 or the complete document 230 or parts of which can be one or more times in a query or storage 240 occur). Furthermore, such a query may additionally contain logical (eg AND, OR ..), bit-wise (AND, OR, NOT) and semantic links (eg inside, outside, part of, similar to ...).

In 2a were from a client 110 Radio information revealed in his environment. This can be done by sensors or other means. An example, like a client 110 transmit such radio information 210 may be sending or receiving network connections or discovery requests from Wifi base stations or reading out the information of the mobile service provider and its data from the operating system (detailed procedures are known in the art and described in the referenced projects and patent applications). Furthermore, distance sensors, position sensors, acceleration sensors, cameras and all other sensors can be used, which are now installed in smartphones. Also, the radio information could be enriched or enhanced by user interaction. User interactions could be acknowledgments of the user of radio information, but also data automatically generated from user interactions, e.g. B. movement pattern, which then z. B. be used to a pre-filtering or enrichment of wireless information.

It is also conceivable to enrich the wireless information by pictures from at least one smartphone camera and z. B. to use these images directly as part of the radio information. It is also possible to use methods from image processing to z. B. key points and feature vectors in the radio information store (eg with methods such as SIFT, SURF, FREAK, BRISK, FAST or other similar - For example, the openCV library can be used for the calculation of the algorithms for key points and Features ("Keypoints and Descriptor matching extraction")

A client 110 transmitted 210 Radio information and optional by query documents 240 to a functional informationable database 200 , A query 240 can also be a request to save a document and a query can be like a document 230 be or include such. The func-formative database 200 can be documents associated with wireless information 230 are managing, storing and performing classical queries and / or calculations due to this. The transmission 210 can be performed immediately after finding the wireless information and one or more of the surrounding wireless networks 130 are used for this purpose or the radio information can at a later time via another network 130 to the func-formative database 200 be transmitted.

The func-formative database 200 receives the radio information of a client 110 and then compares them with the radio information and documents 230 that are stored in the database.

These stored documents and wireless information 230 can be stored in an in-memory database, a SQL database, but also in a NOSQL database (eg graph database, such as Neo4J or document database, such as MongoDB). All forms such as documents can be secured, even distributed systems or other servers are conceivable here. Optionally, however, a database is used that is an association of documents with radio information 230 directly in a record.

A comparison described above can be done by a query, such. B: "All documents that match at least one Wifi BSSID or cell phone cell identification". The result set can then be finely adjusted by subsequent filtering or connectivity based on signal strength in decibels of Wifis or mobile reception strength of the surrounding mobile radio cells is made. Such a fine adjustment can be done in application memory but also directly when querying a database. All documents for which a comparison was positive (the comparison criteria were fulfilled sufficiently or better) then become part of the result set. The result set can then be saved or stored on a data medium or in the working memory. Another and complementary variant is the result set as a result to the query user (here the client 110 ), such as B. by 220 is indicated.

Fig. 2b

2 B , shows the invention described above as a method. The order of steps is interchangeable and not necessarily bound to the following description. Furthermore, it is possible for steps to be performed in parallel, but the steps will be described in order to provide a better understanding. Because of the equivalence between methods, arrangements and systems, therefore, only the basic steps of the method will be described and these should always be considered in combination with the further descriptions of this disclosure. In a first step 300 will at least be a document in a functional information database 200 associated with at least one radio information and optionally stored on at least one disk or held in memory. This association is then in the second font 310 with a second radio information and optionally with an additional document 240 queried. This second radio information can, for. By examining wireless networks in the vicinity of a client 110 but also from the main memory or other data carriers of the client 110 to be read. in the third step 320 The radio information and documents in the query are used to compare with documents and radio information 241 ) in the database. The comparison will be in a fourth step 330 used to determine a result set based on the comparison. The result set can then z. B. returned to a client 220 ,

Fig. 3

3 shows an alternative embodiment of the invention, in the func-formative database 200 directly on the client 110 is available. It is important to mention that the execution of 2 of course also in combination with the execution of 3 , can be used together or alternatively. 3 shows here the extended possibility that not necessarily continuous contact between clients 110 and a functional information-capable database 230 over computer network 130 must exist as an alternative func-formative database 200 on the Client is located. Here, all communications are done as before, but the full interaction is on a client 110 yourself instead.

It is worth mentioning that a transmission over a computer network 130 to another func-formative database ( 210 / 700 ) is possible at a later date, such. B. may take place a transmission, if z. B. a reliable communication process over a computer network 130 can be guaranteed, for. For example, if a client 110 connects to a wifi

Fig. 4.

4 , Shows in 230 an exemplary data structure (in a Java Script Object Notation (JSON) -like structure), such as radio information and associated documents 230 can be represented.

Document in 230 / Fig. 4

Documents (an example can be found in 4 "Document") can have a variety of information and z. B. contain semantic classifications or information, such as the document on clients 110 should be displayed (eg as a question, rating or text with image, a combination of the previous or similar, which may each lead to a different representation).

Furthermore, documents may also have unique identifiers (GUID - Global Unique Identifier), which may be, for. By cryptographic techniques on the client 110 itself or a server. Within the scope of the invention, GUID identifiers can also have more or fewer than 128 bits and they must be equated completely with all methods or systems that generate UUIDs (Universally Unique Identifier). The generation of GUIDs in the invention can therefore z. By using known methods such as UUID or GUID generation of Java
( http://docs.oracle.com (JavaSE / 7 / docs / api / java / util / UUID.html ). (See also:
http://de.wikipedia.org/wiki/Globally_Unique_Identifier .
http://de.wikipedia.org/wiki/Universally_Unique_Identifier ). In a further embodiment, such GUIDs could alternatively or complementarily also be generated as URIs or URLs which, for. On the user name or the identification of a client 110 be generated.

Such GUID identifiers are especially useful when documents and associated radio information 230 refer to other documents or parts of themselves transmitted separately over computer networks and yet references between the documents on a client 110 itself before the exact location or destination is known. Another example of the usefulness of unique identifiers is the storage of referenced documents or parts of documents in different memory areas. When reading out the document parts, the document parts can be reassembled as a holistic document due to the unique identifier without the need to refer to the memory areas in the documents themselves.

Furthermore, visibility options can be specified in the document, which other clients 110 the document and / or the radio information 230 may call. Furthermore, it is possible in the document users or clients 110 to specify those who marked the document as logically saved. This logical memory tag allows the same document to be defined as stored by multiple users without the need to duplicate the document. Also worth mentioning is the possibility of defining logical places and references to them in the vicinity or in the vicinity (eg in the vicinity of supermarket XY, in the Durlach or the like) and the exact or inaccurate distance.

For all the possibilities mentioned above and the others in 4 It should be noted that such a document does not necessarily have to contain all the information itself. Much more came such a document and the associated radio information 230 be represented by all the possibilities described in this application, which may be a document, such. For example, a document and the associated radio information 230 distributed across multiple volumes, databases and tables or records therein.

Radio information in 230 / Fig. 4

As can be seen, a plurality of geographic coordinates may be in radio information 230 To be defined. Here, the origin (how the geocoordinate was revealed) is also defined. This allows geocoordinates from a variety of sources to persist simultaneously with their associated time when they were designated or used. The coordinates themselves consist of accuracy and in addition a further radius, the z. B. can be given by a user as visibility and longitude, latitude and altitude. Furthermore, a coordinate or collection of coordinates also includes one or more classifications. For example, if there is one direct coordinate or if there are several that span a polygon, or if the coordinate z. B. is the center of a radius (eg large building area, village or district). Furthermore, several of these geo-coordinates may also be complementary or aggregated.

Mobile cell data may also contain a plurality of information, such as. For example, which mobile service provider is available and to which the mobile client is connected at the time of the measurement. For example, all the technical data, the cell identification (Cid) or the surrounding mobile radio cells and other data that can be detected with the current state of the art, be part of the cell data. Furthermore, the entry date can also be entered here. In the mobile cell data, it is still possible this also from several clients 110 to combine and z. B. Cellular cell data of a provider with mobile cell data from other providers to enrich. Also here aggregates are possible, which are formed over several mobile data records.

Similarly, the Wifi information. Here are Wifi computer networks 130 in the environment of the client 110 Listed and defined information about the reception strength and / or whether a client is connected to a Wifi network. As before, these data can also be shared by multiple clients 110 aggregated or supplemented.

As before, Bluetooth data from surrounding devices or Bluetooth beacons can also be detected. It is also possible to store data about surrounding magnetic fields. At the same time, data from the camera sensor, such as images or image features, can be stored. Basically, every sensor on the mobile phone can serve as a source of information here. In order to perform advanced calculations and at least an optimization and / or normalization, it is also possible to save the orientation of the client. In order to make distinctions between clients (eg normalizations) or in other cases, the information about the user or the device may also be part of the radio information. Likewise, radio information acquired at an earlier point in time can also be appended. Finally, there is the possibility to attach aggregates of several radio information.

Previously, data aggregation was named several times. Such an aggregate can, for. B. about adding the signal strengths average calculation. Another possibility of aggregation is to count the frequency of existing networks and to classify their importance. Furthermore, a normalization, such. B. via a logarithmic scale. Also, normalizations or device-specific normalizations can be carried out by data mining methods.

Fig. 5

5 shows an exemplary representation of comparisons of radio information based on wifis and mobile radio cells. Comparison 1 can with the radio information and optionally a query document 240 from the client 110 proceed as follows:
A comparison of all Wifi BSSIDs of the query 240 a client 110 with the Wifi BSSIDs in the data-aware database 200 , This comparison can also check if the client 110 also associated with the same wifis as the records 230 in the func-formational database 200 , Furthermore, the comparison can check whether at least one identical Wifi or radio network is listed in the form of a same mobile radio cell identification or BSSID.

The result set (not shown in this 5 but in other figures as 220 in this case includes documents 1, 2 and 3, since record 1 is also listed with BSSID aaaaaa as a connected network; Record 2 is in the result set because aaaaaa is within range; and record 3 because the same mobile cell is listed as a neighbor cell.

In Comparison 2, another example can be seen. Here is the client 110 about limited radio information 240 and only two wifis exist in his radio information 240 and both are marked as disconnected (one can imagine that client 2 does not have the appropriate network key for Wifi aaaaaa and bbbbbb). A comparison with the functional information-capable database 200 on the condition that the client 110 when uncovering a document for the result set must be connected to the same Wifi network to reveal the corresponding records, the result is as follows: As a result 220 only document 2 is revealed. Record 3 is not found in this comparison because it has no information about a Wifi.

The nonexistence of record 1 in the result set 220 shows a filter option of the invention that can be used for security purposes: In this example, only information to clients 110 Transmitted, which have the same connection to the corresponding Wifi. Disconnected clients 110 who do not have connectivity to WIFI aaaaaa will not see record 1.

It should be noted that a comparison could also be limited due to neighboring cells, or logical AND / OR operations may condition or equalize the existence of different networks. In an implementation such comparisons can be realized with a database or similar means in the z. B. one or more indexes BSSIDs or cell phone cell identification can be set to increase the comparison speed.

Furthermore, further criteria can be incorporated in such a query, such as document filtering due to hashtags, words or the like, the result set 220 expand or limit. For example, in documents, hashtags such as "#lecker" and / or "# doner" and / or places like "@Karlsruhe" could be defined. A client 110 could now also define hashtags and locations in its query, and these could be used as another comparison and / or filter of the records. Thus, not only the radio information would be compared but also the semantic information at the same time. Of course, all other features of a query document 240 and a document associated with radio information 230 are used for further comparisons whose use affects the compilation or relevance sorting / relevance classification of the result set.

In another embodiment, not just a result set 220 but also a relevance can be calculated. Such relevance can, for example, by calculating the decibel (DB) difference of each computer network 130 the radio information of the client 110 happen. The previously described filtering of unconnected Wifi networks can also be used as relevance.

Furthermore, in an expanded embodiment, a sorting of the relevance due to the radio information can also be undertaken. This can be expressed, for example, by sorting a list of relevant documents in which documents with similar radio information as the radio information of the query are at the top of the list. Optionally, such sorting can also result in coloring or filtering of the documents that were generated only in the same Wifi as the connected Wifi network in the radio information of a query.

Fig. 6

6 shows a further embodiment of the invention in which mechanisms for enriching radio information can be used. The invention receives radio information of a client 110 /Step 600 , Here also documents with radio information can be associated. As previously saves (step 610 same procedure as 210 ) the invention the information in the func-formative database 200 , An example could be radio information with only wifis. Thereafter, the radio information of a second client 110 in step 620 receive. These contain, for example, GPS data and an identical Wifi network as the first radio information and mobile cell data. In a further step ( 630 ) compares the invention as in previous embodiments, the radio information of the second client with the database and reveals the information of the first client due to the same Wifi network. Due to this, the record of the first client is extended, and then radio information of the second client becomes 110 entered.

• – Alle Funkinformationen in demselben verbundenen Wifi, wie die Funkinformationen des Klienten erhalten den Indikator 0;
• – Alle Funkinformationen, die gleiche Wifis in der Nähe gelistet haben erhalten: = (Anzahl derselben gelisteten Wifis)/(Anzahl der gelisteten Wifis der Funkinformationen des Datensatzes) .(„/” = geteilt durch)
• – Selbige Berechnung wie zuvor ist auch mit weiteren Funkinformationen, wie Mobilfunkzellen möglich.
• – Weiterhin können Koordinaten aus den Funkinformationen mit Abstandsmessungen in die Berechnung einfließen.
• – Alle Indikatoren der zu vorigen Berechnungen können addiert werden.

In a further embodiment, the radio information for the representation in at least one client 110 used by the wireless information of a client 110 with the radio information from the result set 220 be compared. Such a representation can, for. B. on a color or a partially filled bar or a similar mechanism. The calculation that serves as the basis can be done on the basis of rules or a formula: eg

• - All radio information in the same connected Wifi, as the wireless information of the client get the indicator 0;
• - Received all wireless information that has the same Wifis nearby: = (Number of same Wifis listed) / (Number of listed Wifis of radio information of the data set). ("/" = Divided by)
• - Same calculation as before is also possible with other wireless information, such as mobile radio cells.
• - Furthermore, coordinates from the radio information with distance measurements can be included in the calculation.
• - All indicators of previous calculations can be added.

The added indicator is then used to represent the similarity. In addition, the indicator can also be divided into classes (eg 0, 1-4, 5-10 ...), which are then used in the presentation, such as. B. a bar is filled due to the indicator or a performing element is colored in different colors.

Fig. 7

Another embodiment of the invention makes it possible locally on the client 110 Store radio information associated with documents 210 and this later 700 to a database via at least one computer network. This is done as follows:
A client 110 creates or specifies a document (eg, by user input) and determines radio information in its environment 240 , He saves this ( 210 ) then in its local functional information database 200 , At a later date, this information (associations in 230 ) from the local func-formational database 200 via at least one computer network to another funkinformationsfähige database 200 transfer 700 , In this transmission, the radio information before the storage process on the other funkinformationsfähigen database 200 to be enriched. For example, it is possible that in the enrichment geo-coordinates to Wifi, cell phones or similar wireless information are determined and these data are then additionally stored. The enrichment with radio information of another client, which was made in the preceding description, can also be particularly advantageous here.

Furthermore, the step of transmitting the data from the client 110 also linked to events. For example, it is possible the network connectivity of the client 110 to monitor and start the transmission at the moment (or shortly after) when a client has connectivity to the Internet.

Fig. 8.

8th shows the previously described time-shifted data transmission of 7 as a procedure. In the method, the steps need not necessarily be exchanged in the order described as follows. Furthermore, the method can be extended with all features in this document. The process is exchangeable and expandable with the previous description. All in the method and previously described features are combinable.

In the process is in step 800 on a client 110 creates a document or references another document. This can be z. For example, a user input may be like a text or a user may refer to a photo, video, or the like.

In a further step ( 810 ), radio information is received at the same time (or before or after) (user interaction, such as starting to enter a text, may also initiate steps to seek and obtain radio information).

In step 820 the radio information is then associated with the document and in the client 110 stored. Such a filing may be saving to a disk in the client 110 be, but also that in memory hold the information. All of the techniques known from the prior art can be used here to realize a local func-formatable database.

In a further step ( 830 , in 7 as a step 700 shown), the wireless information and documents are transmitted from the local database via at least one computer network. Preferably, the destination of the transmission is another functional information-capable database 200 who are in another client 110 or a server located on the Internet. Particularly preferably, this may additionally have the ability to enrich the data before storage, optionally via third-party systems.

The present invention, method, arrangement and apparatus can be particularly preferably used to store information within buildings only on the basis of radio information. This is particularly advantageous if no GPS signal can be received in buildings.

Another particularly preferred application is advertising with the invention to mobile clients 110 to deliver / to determine. This happens z. B. by the use of wireless information and determine the appropriate advertising due to this. An embodiment of the invention, this z. For example, one or more advertisements themselves or a reference to them will appear in the documents associated with radio information 230 saved. Optionally, additional information can be stored in this advertising / documents. The determination of appropriate advertising in the form of radio information associated with documents 230 , can be solved with the help of various aspects of the invention. For example, due to the high flexibility in determining / querying documents, a functional information-capable database 200 , Radio information as well as features in documents 240 be used to uncover appropriate documents / records and to assess their relevance. Furthermore it is possible queries 240 and the associated result set 220 influenced by several criteria. For example, advertisers may provide a monetary amount for delivery associated with particular wireless information and this will be reflected in the documents associated with wireless information 230 , deposited as a feature. This feature can, for. B. evaluated together with the decibel level (DB) of the surrounding radio networks, associated with a comparison with the radio information and documents 230 then be additionally used as a filtering or evaluation criterion. The invention then determines z. B. the strongest wireless network (eg., Signal strength of a Wifi) and determines which advertising has offered the highest amount of money for this wireless network. The result set is prepared accordingly. On a client 110 This result set is then used to display (for example, first in a list) the advertisement with the highest sums of money from the strongest wireless network.

It should be noted that this invention or group of inventions can be implemented as computer-implemented systems or as computer programs. Due to the nature of this invention, all of the illustrated facts in different programming languages can be implemented on different platforms. In addition, all procedures can be represented in declarative programs and thus in declarative situations and vice versa. Likewise, the processes can be converted as apparatuses or arrangements and vice versa. Therefore, the invention can be combined particularly advantageously with other inventions, systems and programs which are already known in the prior art. For example, one can use the invention together with the referenced in the introduction of this document inventions together particularly advantageous. In addition, because of the flexible nature of the invention, many individually discussed parts of the invention may be combined or rearranged to provide better solution solutions at higher speed or otherwise. Therefore, the description of the invention is to be understood as an exemplary embodiment, the features of which may also occur in other arrangements.
