Description

User equipment location indication method and access point device The present application claims to be filed on March 18, 2009 by the Chinese Patent Office, the application number is 200910129419.6, and the invention name is "user equipment location indication method and access point device" Priority is hereby incorporated by reference in its entirety. TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a method for indicating a location of a user equipment and a corresponding access point device. Background of the Invention With the development of communication technologies, a femto-Cell networking scenario has appeared in the 3rd generation (3G, The 3rd Generation) network. In the Femto-Cell networking scenario, users deploy access point (AP, Access Point) devices with small coverage, such as home gateways, home base stations, and small base stations, at a fixed location (such as a home or a company). Access to the wireless communication user equipment. These AP devices are usually connected to the Internet through a DSL (Digital Subscriber Line) and then connected to the mobile core network through an Access Gateway (AG, Access Gateway). Since the user accesses the AP cell without using macro network resources when using the service, it can enjoy lower tariffs and high-speed network services.

Generally, the location where the AP device is deployed is also covered by the macro cell. The user needs to know whether the current location resides in the macro cell or the home AP cell to know exactly whether the current service is to enjoy the AP cell preferential tariff or the macro community tariff. Therefore, a mechanism is needed to provide users with appropriate location indication information to avoid charging disputes when users use the service within the home range.

Currently, the short message-based location indication scheme is adopted: After the user equipment (UE, User Equipment) enters the AP coverage area and completes the location/routing area update (LAU/RAU), the AP directly transmits (Direct Transfer) message to the AP. The UE sends a prompt short message to inform the user that the AP cell has been entered. The type of the prompt message is usually a lightning short message, which is automatically deleted after the user confirms.

In the course of research and practice of the above scheme, the inventors of the present invention found that it exists at least The following disadvantages: When the UE enters the AP cell, the AP can send a short message to prompt, and when the UE leaves the AP cell to enter the macro cell, the macro cell does not send a short message to the UE, so the user cannot know the location information. SUMMARY OF THE INVENTION Embodiments of the present invention provide a method for accurately indicating a location of a user equipment and a corresponding access point device.

A user equipment location indication method includes: an access point device determines user equipment access; an access point device sends a location indication program to a user identity card of the user equipment, and the location indication program includes a location update event subscription program and location Updating the event triggering program; wherein, the location update event subscriber is configured to subscribe the user identity card to the user equipment's mobile terminal for a location update event, and the location update event trigger is used to cause the user identity card to receive the location update event reported by the mobile terminal After obtaining the location information of the access point device and comparing with the current location information of the mobile terminal, if the same, the mobile terminal is prompted to make a prompt to enter the access point cell, and if not, the mobile terminal is triggered to be not in the access point cell. prompt.

An access point device, comprising: an access module, configured to access a user equipment; and a download service module, configured to send a location indication program to a user identity card of the user equipment after determining that the access module accesses the user equipment; The location indication program includes a location update event subscriber and a location update event trigger, wherein the location update event subscriber is configured to subscribe the user identity card to the user equipment's mobile terminal for a location update event, and the location update event trigger is used.

The embodiment of the invention provides a user equipment location indication method, where the access point device sends a location indication program to a user identity card of the user equipment, and the user identity card implements the program to implement the location indication. The embodiment of the invention also provides a corresponding access point device. The details are explained below. The basic flow of the embodiment of the user equipment location indication method of the present invention can be referred to FIG. 1, which mainly includes the steps:

101. An access point (AP) device determines user equipment (UE) access.

After the UE enters the coverage of the AP cell, the AP can access the AP. This process can be performed by referring to the existing execution method. For example, for an AP with admission control, the process may include a process of making an admission determination to the UE based on the user identity of the UE.

102. The AP sends the location indication procedure to the user identity card of the UE.

The user identity card referred to herein may be a smart card with a microprocessor that provides user identity authentication for the network. Depending on the type of application network and the scenario, there may be various forms of expression, such as a Subscriber Identity Module (SIM) in the Global System of Mobile Communication (GSM) network, and code division multiple access ( CDMA, Code Division Multiple Access) Mobile User Identification in the Network

(RUIM, Removable User Identity Module) card, universal mobile communication system (UMTS, Universal Mobile Telecommunications System)

(UICC, Universal Integrated Circuit Card) and Universal User Identification (USIM, Universal SIM) card etc.

The user identity card in this document can interact with the mobile terminal (ME: Mobile Equipment) of the UE in the application toolkit. The so-called application toolkit is actually a set of instructions, which specifies the user identity card how to interact with the outside world, and expands the communication protocol between the user identity card and the mobile terminal, so that the user identity card can be moved. Play more aggressively in the terminal. Currently, the types of application kits include: SIM Toolkit for GSM networks (STK, SIM Application ToolKit), RUIM Application Toolkit for CDMA Networks, USIM Toolkit for UMTS Networks (USAT, Universal SIM Application Toolkit) ) and USIM toolkit interpretation (USAT-I, USAT Interpreter) and so on. Taking GSM as an example, at present, GSM has identified SIM toolkit standards, such as 081^1:11.14, 02.19, 11.11, etc. These standards allow a large number of small programs running in the SIM to initiate SIM operations on mobile terminals that meet the above criteria. For example, interacting directly with the user, etc. by setting menus, implementing inputs and outputs, etc. on the mobile terminal. In summary, the use of the application toolkit provides an active control interface to the mobile terminal for programs running within the user identity card.

For the sake of brevity, the following uses "SIM card, instead of" user ID card, for explanation.

The location indication program sent by the AP to the SIM card can contain two parts:

1 location update event subscriber. This program is used to make the SIM card update the event to the ME subscription location. After the subscription is executed, the ME reports a location update event to the SIM card when a location update occurs. For example, after the location update occurs and the AP camps on the AP cell, the ME obtains the location update information by receiving the AP cell broadcast information, and then reports the obtained location update information to the SIM card through the "Report Location Update Event".

2 location update event trigger. The program is configured to enable the SIM card to obtain the location information of the AP and compare it with the current location information reported by the ME after receiving the location update event reported by the ME. If the same, the SIM triggers the ME to make a prompt to enter the AP cell. Trigger the ME to make a prompt not to be in the AP cell. The so-called entry prompt can be a voice prompt, a text message displayed on the screen, or both. The prompt that is not in the AP cell may be a voice prompt, a text message displayed on the screen, or both. It is worth noting that when making a prompt of "not in the AP cell", the user may move from the AP cell to the macro cell, or may move between the macro cells. If the two cases are not distinguished, "nowhere" The prompt in the AP cell can be set to the text prompt when idle, so as not to interfere with the user; of course, the information of the previous location update can be further recorded, and before the prompt of "not in the AP cell" is made, according to the record The situation is differentiated. If it is determined that the AP cell is moved to the macro cell, a voice prompt can be made. If it is determined that the location is updated between the macro cells, no prompt is given, or only a text prompt is presented.

The location information of the AP can be saved in the SIM card in advance, or it can be obtained from the AP in real time by the ME. Optionally, the AP may send the location information of the AP to the SIM card when the location indication program is sent. In this case, the location update event triggering program acquires the location information of the AP, specifically, the AP that has saved the SIM card. Location information. The location information of the AP may be the identification information that is allocated to the AP based on the network plan, and may be the cell ID (Cell ID) of the AP, or the location area code (LAC) of the AP. Or the service area code (SAC) of the AP, etc., using these types of location information to perform location comparison with the current location information of the mobile terminal of the user equipment, and can perform location update between the AP cell and the macro cell for the user equipment. Provide accurate location indication information.

In order to send the location indication program to the SIM card, the AP needs to provide a program download function. In general, APs can use the over-the-air (OTA) technology for program push. The OTA is a technology that uses the air interface of a mobile communication network (for example, GSM/CDMA/WCDMA) as a bearer, and uses OTA commands to implement interaction between the UE and the SIM card to remotely manage data and applications in the SIM card. The air interface can use the Wireless Application Protocol (WAP) / General Packet Radio Service (GPRS), Wireless Internet Browser (WIB), CDMA1X, and other popular shortcomings. Messaging technology. Of course, other wireless or wired download methods are also possible. For example, the UE can connect to the AP through a Universal Serial Bus (USB) interface and download the program through the USB interface. As an optional manner, the steps 101 and 102 may further include the following steps:

102a, the AP sends an access point function menu (which can be called a FemtoZone menu) to the SIM card of the UE. The FemtoZone menu contains:

1 AP location information setting item. It is used to enable the SIM card of the UE to save the location information of the AP device under the item. 2 location update event application. It is used to enable the SIM card of the UE to install the location update event subscriber and the location update event trigger under the item.

Step 102a causes the AP to install the FemtoZone menu on the SIM card before or at the same time as the push position indication program, and the content in the position indication program is a sub-item of the FemtoZone menu. This menu-based approach facilitates the AP to provide services on the one hand. For example, if the AP subsequently expands the new service function, the FemtoZone menu (adding or updating sub-items) can also be refreshed through the OTA download to conveniently provide users with rich service content. On the one hand, it also facilitates the SIM card to present the business function to the user, providing the user with a personalized entry. Of course, items in the FemtoZone menu that do not require user intervention (such as the location update event application) can be shielded from the user.

Based on step 102a, it is further preferred that the FemtoZone menu further comprises:

3 personalized reminder settings. The interface for enabling the SIM card of the UE to provide a prompting manner to the user through the UE. Through this interface, the user can set the prompt mode when the mobile terminal enters and/or is not in the AP cell. For example, the text content displayed by the mobile terminal when entering and/or not in the AP cell, or the manner of display, or the prompt tone used, etc., is set.

It should be understood that the FemtoZone menu may also include other functional items, such as a "Location Update Settings" item that provides the user with an on/off location update indication function, and may also include a "Menu Download" item, which the user can actively select by selecting the item. Update the download. An example of a FemtoZone menu structure is shown in Figure 2. As an alternative, the AP may perform the following steps before sending the content (FemtoZone menu, location indication program, etc.) to the SIM card of the UE:

102b, the AP determines whether the FemtoZone menu and/or the location indication program has been sent to the SIM card of the UE. If the result of the determination is that the result has been sent, the AP does not send. If the result of the determination is no, that is, if the result is not sent, the AP transfers to The steps to send the FemtoZone menu and/or location indicator.

Correspondingly, the AP needs to perform the following steps after sending the FemtoZone menu and/or location indication program to the SIM card of the UE:

102c. The AP record has sent the FemtoZone menu and/or location indication program to the UE's SIM card.

This will prevent the user from downloading the FemtoZone menu and/or location indication program each time they enter the AP cell, saving resources. As an optional implementation, if the SIM card is a Java-enabled card, the content sent by the AP (FemtoZone menu, location indicator, etc.) can be implemented as a Java program, and downloaded to the Java card by the OTA method, by the Java card. The bytecode interpreter or virtualizer executes. The specific implementation process may include: 1 in the Java Card Run Time Environment (JCRE, Java Card Run Time Environment), using the Java Card Development Kit (JCDK, Java Card Development Kit) application programming interface (API, Application Programming Interface) to write the location Indicate the program. 2 Use the JCDK tool to compile the Java program and convert it into the Application Protocol Data Unit (APDU) bytecode format according to the Global Platform (GP, Global PlatForm) protocol, and then convert this APDU code into the APDU format code of the short message. . 3 The short message byte code is downloaded to the SIM card in the UE by the OTA method, and is installed in the SIM card in the UE in the manner of menu application, and the location indication program can execute its application function.

The foregoing embodiment of the user equipment location indication method adopts a manner in which the AP sends the location indication procedure to the SIM card of the UE, and the SIM card can determine whether to enter or leave the AP cell when the location update occurs in the UE by executing the location indication procedure, and trigger The UE makes a corresponding prompt, so that the user can accurately know the current location information. If the AP further installs the FemtoZone menu to the SIM card before or at the same time as the push location indication program, on the one hand, it will facilitate the AP to expand or refresh the service function, and on the other hand, it is convenient for the SIM card to present the service function to the user, and provide the user with the personality. The setting of the entrance. In addition, if the AP further determines that it has not been pushed before pushing the content to the UE, it can prevent the user from downloading the FemtoZone menu and/or the location indication program and saving resources each time entering the AP cell. The following describes an embodiment of the access point device of the present invention for performing the above-mentioned user equipment location indication method. The basic logical structure refers to FIG. 3, which mainly includes the access module 201 and the download service module 202 of the communication connection.

The access module 201 is configured to access a user equipment.

The download service module 202 is configured to provide a download service to the accessed user equipment, including a user identity card that sends the location indication program to the user equipment.

The so-called location indicator includes a location update event subscriber and a location update event trigger;

The so-called location update event subscriber is used to subscribe the user identity card to the mobile terminal where it is located. Location update event;

The location update event triggering program is configured to enable the user identity card to obtain the location information of the access point device after comparing the location update event reported by the mobile terminal, and compare with the current location information of the mobile terminal, and if the same, trigger the mobile terminal A prompt to enter the AP cell is made, and if different, the mobile terminal is triggered to make a prompt not to be in the AP cell.

The download service module 202 is further configured to: when the location indication program is sent to the user identity card of the user equipment, send the location information of the access point device to the user identity card of the user equipment.

Preferably, the download service module 202 may further have a menu download function for transmitting an access point function menu to the user identity card of the user equipment.

The so-called access point function menu includes, the access point location information setting item, and the location update event application item;

The so-called access point location information setting item is used to enable the user identity card of the user equipment to save the location information of the received access point device under the item;

The so-called location update event application is used to enable the user identity card of the user device to install the location update event subscriber and the location update event trigger under the item.

Further, the so-called access point function menu may further include: a personalized prompt setting item, configured to enable the user identity card of the user equipment to provide an interface for setting a prompt mode to the user through the mobile terminal of the user equipment; The incoming and/or not in the AP cell may be prompted according to the prompt mode set by the user.

In addition, the download service module 202 may specifically adopt a structure including a first unit 2021 and a second unit 2022, where the first unit 2021 is configured to provide content (access point function menu and/or location indication program) before downloading. First, it is determined whether the content has been sent to the user identity card of the user equipment, and the second unit 2022 is configured to perform the sending of the content when the determination result of the first unit 2021 is negative; accordingly, the download service module 202 can After the access point function menu and/or location indication program is sent to the user identity card of the user device, the record has been sent to the user identity card of the user device.

The download service module 202 can preferably transmit the location indication program to the user identity card of the user device using over the air download technology. This can be achieved by integrating the OTA service functions into the AP, making the AP an access point device with integrated OTA functionality. For a better understanding of the foregoing embodiments, a specific application scenario is taken as an example for description. As shown in FIG. 4, the networking diagram includes an access point device AP OTA Server 301 having an OTA service function, and a user equipment UE 302 (including a mobile terminal ME 3021 and a SIM card 3022). The AP OTA Server 301 communicates with the UE 302 over the air interface, uses the OTA to push content to the UE 302, and the ME 3021 and SIM card 3022 can interact using OTA commands.

Scenario 1: UE 302 enters the coverage of AP OTA Server 301 for the first time. It is assumed that the AP OTA Server 301 is an AP with admission control, and the UE 302 is allowed to access (for example, after the home user purchases and installs the home base station, it first powers on the network, and the home base station is set by the user to allow only specific users to access. ). The signaling process in this scenario refers to Figure 5, including:

1 AP OTA Server establishes a Radio Resource Control (RRC) layer connection with the UE;

2 AP OTA Server judges that the FemtoZone menu and location indication program have not been sent to the UE according to the user identity obtained in the admission control, so the FemtoZone menu is used by the OTA function.

(See Figure 2) Pushing (PUSH) to the ME of the UE;

3 ME will save the obtained FemtoZone menu command (PUSH) to the first level menu of the SIM card. (For the sake of brevity, the subsequent OTA download of the AP OTA Server to the UE is directly described as the download of the AP OTA Server to the SIM card, and is no longer divided. Two steps);

4 AP OTA Server downloads the location information data (LAC + CELL ID or SAC) of the AP through the OTA to the SIM card;

5 AP OTA Server downloads the location update event (SET UP EVENT, location status event) to the SIM card through the OTA;

6 SIM card subscribes to the location update event to the ME;

7 AP OTA Server downloads the Location Status Event trigger program to the SIM card through the OTA.

After the above scenario, the SIM card 3022 of the UE 302 has the function of performing the location indication, and the AP OTA Server correspondingly records that the FemtoZone menu and the location indication program have been sent to the user.

Scenario 2: The UE 302 switches between the macro cell and the AP cell of the AP OTA Server 301. Assume that the UE 302 first enters the AP cell from the macro cell and then enters the macro cell from the AP cell. The signaling process in this scenario refers to FIG. 6, including:

1 When the UE enters the AP cell from the macro cell, the UE updates the location and camps on the AP cell, and the UE reports the location update event to the SIM card through the OTA event download command. (Location status change );

2 The SIM card triggers the location update event application, and compares the current location information with the location information of the saved AP (for example, LAC + CELL ID or SAC), and the comparison result is the same;

3 The SIM card triggers the ME to make a prompt to enter the AP cell, for example, actively initiates a "SET UP IDLE MODE TEXT" command to the ME, so that when the UE is in an idle state, the location indication information is displayed on the screen (for example) "Welcome to FemtoZone", etc.; Of course, it is also possible to send a voice prompt; the specific form and content of the location indication information can be set on the FemtoZone menu by "personalized prompt setting";

4 When the UE leaves the AP cell and enters the macro cell, the UE performs location update and camps on the macro cell, and the UE reports the location update event to the SIM card through the OTA event download command.

(Location status change );

5 The SIM card triggers the location update event application, and compares the current location information with the location information of the saved AP, and the comparison result is different;

6 SIM card triggering The ME makes a prompt not to be in the AP cell, for example, firstly initiates a SET UP IDLE MODE TEXT (length=0) command to the UE, and cancels the location indication information displayed on the screen when the UE is in an idle state;

7 The SIM card sends a Display Text command to the ME to prompt the user that the user is not in the AP cell.

The user equipment location indication method in the embodiment of the present invention adopts a manner in which the AP sends the location indication program to the SIM card of the UE, and the SIM card can determine whether to: 3⁄4/out the AP cell when the location update occurs by the UE by executing the location indication procedure. And triggering the UE to make a corresponding prompt, so that the user can accurately know the current location information. If the AP further installs the FemtoZone menu to the SIM card before or at the same time as the push location indication program, on the one hand, it will facilitate the AP to expand or refresh the service function, and on the other hand, it is convenient for the SIM card to present the service function to the user, and provide the user with the personality. The setting of the entrance. In addition, if the AP further determines that it has not been pushed before pushing the content to the UE, it can prevent the user from downloading the FemtoZone menu and/or the location indication program once every time the AP cell is entered, thereby saving resources. A person skilled in the art can understand that all or part of the steps of the foregoing embodiments can be completed by a program to instruct related hardware. The program can be stored in a computer readable storage medium. The storage medium can include: Read only memory (ROM, Read Only) Memory ), random / ^ Take memory (RAM, Random Access Memory), disk or CD.
