Description

Improvements, in or Relating to Information Distribution
The present invention relates to a system, receiving terminal and method for the distribution of information of limited geographical interest
An individual who is travelling and temporarily located at a place geographically remote from his normal home location, i e office, or residence, frequently needs to have access to information concerning his/her current location Such information may be available on the Internet and, if it were possible to access that information with relative ease, would represent a valuable resource for travellers
Unfortunately, at the present time, there is a vast volume of information available on the Internet and the amount of available information can be expected to grow, in the future, at an ever increasing rate This means that the difficulty and time spent locating relevant information is a real obstacle to the use of the Internet, especially for an individual who is away from his normal location and contacts, and may be unfamiliar with the location of information relevant to his current location on the Internet From the point of view of the information provider, this makes it very difficult to effectively target information, and advertising, to an intended audience
There are many organisations, such as garages, filling stations, restaurants, weather forecasters, etc , interested in accurately targeting locally based information on visitors to their location Equally, many travellers would welcome the opportunity to readily access information on where they can obtain goods and services in a location with which they are not familiar Use of the Internet is growing rapidly and many, if not most, people have at least the rudimentary skills necessary to enable them to access the Internet However, especially for beginners, surfing the Internet is an extremely time consuming and frustrating occupation, in the absence of skilled guidance and knowledge on where to search for data of interest Where the intention is to locate local guides and information, a furtner complication is that the information and guides are continually being updated and changed and it is by no means simple and straightforward to find the correct, or most current guide, or information
The problem, to which the solution proposed by the present invention is directed, is to provide a method whereby a traveller currently located in a location with which he is not familiar can easily access information, relating to his current location, over the Internet, or from some other computer system
The present invention provides a solution to this problem by using a telephone system, which may be either the PSTN, or a mobile cellular system, such as the GSM system, to identify the current location of an individual seeking information relevant to his current location, using data on the individual's current location to automatically locate relevant information on a computer database, or databases, and making this information available to the individual desiring the information. A user's terminal may employ software to generate a menu driven selection process and conceal, from the user, details of the automated process of searching for the most relevant information, thus creating a user friendly system.

According to a fourth aspect of the present invention, there is provided an information user terminal, characterised in that said information user terminal is adapted to operate with a system for distributing information as set forth above, or adapted to operate in accordance with a method as set forth above
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which
Figure 1 illustrates, in schematic form, the operation of one embodiment of the present invention
Referring to Figure 1 , there is shown, in schematic form, a GSM mobile telephone system in which the present invention is implemented Two vehicles 7, and 8, equipped with GSM mobile transceivers linked to portable computers with Internet access software, are shown in local areas 4 and 3, respectively Local areas 3 and 4 have system databases 1 and 2. Each of the local databases 1 and 2 contains a list of "http" addresses to local information servers 5 and 6 associated with local areas 3 and 4 respectively
The system databases 1 and 2 may be associated with mobile switching centres (MSC) for the GSM mobile telephone system Depending on geographic factors, local areas 3 and 4 may be served by a single system database, or, as shown in Figure 1 by separate databases
A signal, S1 , may transmitted from all base stations, of a GSM system, within the defined geographic area 3, at equal intervals of time The signal S 1 is generated via the GSM short message service (SMS) and is a cell broadcast which contains at least one "http" address for local information servers Signal S 1 preferably contains a single "http" address for one local information server, 5, via which, if necessary, any other local information which is available may be accessed, via hyper text marks
Similarly, a signal, S2, may transmitted from all base stations within the defined geographic area 4, at equal intervals of time Again, the signal S2 is generated via the GSM short message service (SMS) and is a cell broadcast which contains at least one "http" address for local information servers Signal S2 also preferably contains a single "http" address for one local information server, 6, via which, if necessary, any other local information which is available may be accessed, via hyper text marks
S3 indicates the exchange of signals required to retrieve information from the home page of local information server 5 via a GSM data channel Similarly S4 indicates the exchange of signals required to retrieve information from the home page of local information server 6 via a GSM data channel
By using a terminal having a GSM transceiver, coupled to a PC with Internet access e g using Netscape, a subscπber can automatically obtain access to information relating to his current location A GSM system operator may choose to provide a home page on the Internet which is specially formatted to provide easy access to the type of local information which a subscriber to the service may wish to access The PC may be equipped with software, provided by the GSM system operator, to facilitate easy access to this service Such software, on actuation, may be arranged to receive the appropriate signals S1 , S2, and automatically access the appropriate home page for the local information servers 5, and 6
Alternatively, the GSM system operator may offer a service to companies and institutions for the distnbution of the "http" addresses of their home pages via
GSM cell broadcasts However, the preferred alternative is for the GSM system operator to distπbute a single "http" address to a local information server via SMS cell broadcasts Clearly, to enable this service to be successfully operated, subscπbers must have access to software which at least has the capability of
receiving SMS messages,
reading out addresses to the local information servers, and
automatically ensuring that the current home page with the requested local information is displayed
Many alternative embodiments can be devised which fall within the spirit of the present invention, for example
1 The system of the present invention may employ a computer-based database which operates independently of the Internet
2 The location of a subscriber to the service may be identified by the GSM network determining the base station used for communication with the subscπber This information can then be used to automatically identify and display on a users terminal a menu driven gateway to information relevant to the user's current location
3 The location of a subscriber may be determined by. a GPS unit built into his/her terminal
4. The system may be based on the PSTN, rather than a mobile telephone system, and a standard calling number identification system may be used in combination with an A-number (standard telephone number) analysis to identify the location of a calling subscriber
5 If a subscπber uses the system via the PSTN, the system may identify the location of the subscriber from the subscriber's IP address
At the heart of the present invention lies the ability of a telecommunications operator to identify the geographical location of a calling subscriber and offer location specific information to that subscriber. The operator may recover the costs of providing this service by charging companies and institutions who wish to use the service to target their information to subscrib(3rs, or by charging subscribers who wish to obtain local information with relative ease, or both.
Some examples of the application of the present invention are briefly set out below:
an individual travelling away from home may have a problem with his car and needs to find the location of the nearest workshop able to repair the car - the system of the present invention can provide him with details of workshop telephone numbers, hours of business etc.;
the system of the present invention may provide a traveller with details of available travel options, including timetables, car hire, etc.;
- restaurants available within reach of a current location, including hours of opening, menus, etc.;
municipal services available in a particular location;
tourist information;
information on medical services, care centres and pharmacies;
- maps of a particular area;
local weather forecasts; and
local traffic information.
Many other variations on the present invention will be apparent to those skilled in the art, for example, the use of audio distribution of certain classes of information to subscribers who are driving a vehicle.
