Description

Method and system for identifying an access network

The present application claims priority to Chinese Patent Application No. 200910003079.2, entitled "Method, Apparatus and System for Identifying Access Network", filed on January 19, 2009, the entire contents of which are incorporated by reference. In this application.

TECHNICAL FIELD The present invention relates to the field of mobile communications, and in particular, to a method and system for identifying an access network. BACKGROUND OF THE INVENTION In order to meet the individualization needs of different user groups, a home base station has emerged in the 3GPP (3rd Generation Partnership Project) communication system. A home base station is a type of base station that is deployed as a dedicated resource for use in homes, groups, companies, or schools to serve specific users. The home base station can be set to allow only certain user terminals with private network rights to camp or access, and at the same time, these user terminals can also reside or access in the public network. Multiple types of networks can exist simultaneously in the coverage of each home base station, and different networks are independent of each other and are respectively directed to different user groups. The user terminal in the Closed Subscriber Group (CSG) can normally access the network for the user group through any one of the home base stations serving the closed user group; the user terminal not belonging to the closed user group In addition to making an emergency call, there is no right to access the network for that user group through the home base station serving this closed subscriber group. Different closed user groups can be distinguished by the identity of the closed user group. On these user terminals, a list of the identifications of closed user groups that the user can join is saved. This list is called a closed user group white list. When the user is authorized to join a new closed user group, or the user is canceled The authorization of a closed user group, the whitelist on the terminal will also increase or delete the identity of the corresponding closed user group. The unique identifier of the closed subscriber group in an access network is the closed subscriber group identity number, and the closed subscriber group identity number is broadcast on the air interface. However, closing the user group identification number is a string of semantic numbers, which makes it difficult for the user to identify, select, and access the closed user group cell with authority. In order to solve this problem, the existing home base station broadcasts the closed user group name string information with semantics while broadcasting the closed user group identity number, and is used to mark the closed user group identity number. The closed subscriber group name is the same as the home base station name, and all home base stations serving a closed subscriber group configure the home base station name as a closed subscriber group name. In this way, by closing the user group name, the user can know which specific access network is indicated by the closed user group identity number, and then make an access selection according to a certain access policy.

However, when a home base station supports multiple closed user groups at the same time, the multiple closed user group names are represented by the same home base station name, so that the user cannot identify each closed user group. SUMMARY OF THE INVENTION Embodiments of the present invention provide a method, apparatus, and system for identifying an access network, such that a user can identify a closed user group to access the network.

DETAILED DESCRIPTION OF THE INVENTION In the following description, for purposes of illustration and description However, the detailed description of well-known devices, circuits, and methods is omitted in the present invention in order to avoid obscuring the description of the present invention. In the technical solution of the present invention, the user terminal (User Terminal) may communicate with one or more core networks via a radio access network (for example, RAN, Radio Access Network), and the user terminal may be a mobile terminal or a fixed terminal. Among them, the mobile terminal can also be called a mobile user. Mobile user equipment (UE, User Equipment), etc., the mobile terminal may be a mobile station, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, may be portable, pocket, handheld, computer Built-in or in-vehicle mobile devices that exchange language and/or data with the wireless access network. An embodiment of the method for identifying an access network by the terminal side of the present invention, as shown in FIG. 1, is mainly as follows.

101. Receive a closed user group identity number broadcast by the home base station, and find a corresponding closed user group indicator in the closed user group white list, the closed user group indicator of the closed user group white list package. 102. Display the indicator. Another embodiment of the method for identifying the access network by the terminal side of the present invention, as shown in Fig. 2, is mainly as follows.

201. When joining a closed user group, adding an identity number of the closed user group to the closed user group white list, and a closed user group indicator corresponding to the closed user group identity number. For example, a closed user group whitelist on a user terminal may generally include an identification number of a closed user group and a closed user group indicator corresponding to the closed user group identification number. In another embodiment of the present invention, the closed user group white list may further include fingerprint information such as a geographical location and a frequency of the closed user group cell, and the user may perform priority configuration and the like. The identification number of the closed subscriber group represents the identity number of a closed subscriber group in a public land mobile switching network. In another embodiment of the present invention, each closed user group indicator may also carry a picture, after the user joins the user organization, the operator organization pushes the user terminal to form a new one. The graphical identifier of the user organization carried in the whitelist can be replaced by other pictures in the user terminal. When a new user is added to the closed user group, the closed user group white list of the user terminal adds an identification number including the closed user group, and corresponds to the closed user group identity number. Closed user group indicator. In another embodiment of the present invention, the identity number of the closed subscriber group is a unique identification number of the closed subscriber group within the public land mobile switching network, allocated by the operator, and the length is within 27 bits. In another embodiment of the present invention, the closed subscriber group identity number includes: a public land mobile telephone network identity number (PLMN ID) and a closed subscriber group identity number (CSG ID). The combination of PLMN ID and CSG ID (which can be expressed as: PLMN ID + CSG ID) is unique worldwide. The closed user group indicator is mapped to the closed user group identity number. Closing the user group indicator includes closing the user group name and/or closing the user group graphic identification. For example, the closed user group name includes: a generalized closed user group name. For example, the generalized closed user group name is composed of a common closed user group name, and the normal closed user group name may be freely defined by the home base station owner or the operator, or may be defined as a closed user group within a certain range. A unique name (for example, globally). When the normal closed subscriber group name is freely defined by the home base station owner or operator, the generalized closed subscriber group name may only uniquely correspond to one closed subscriber group identity number.

When the normal closed user group name is defined as a unique name of a closed user group within a certain range (for example, globally), the closed user group name may include, in addition to the generalized closed user group name, in addition to: Narrowly closed user group name. For example, the narrow closed user group name includes a public land mobile telephone network identifier and a normal closed user group name. For example, each narrow closed user group name uniquely corresponds to a closed user group identity number. In another embodiment of the invention, the plurality of A generalized closed user group name corresponding to a common closed user group name. The name of the closed user group is requested by the closed user group, the operator organization confirms that it is globally unique, and is registered and assigned to the closed user group. Closed user group names can use the registration and management of an Internet domain name, the allocation system. A closed user group name is bound by the operator's organization and can also be associated with a graphical trademark.

For example, for a top-level user organization, CSGNAME.COM can be assigned a generalized closed user group name (CSGNAME.COM is also a normal closed user group name). At this time, the generalized closed user group name is equivalent to the narrow closed user group name of [PLMN X].CSGNAME.COM, where PLMN X can be any PLMN identity that has registered the CSGNAME. Each PLMNXCSGNAME.COM corresponds to the identity number of a closed subscriber group assigned by the PLMN, and CSGNAME.COM corresponds to the identity number of the closed subscriber group of the organization for all PLMNs. The closed user group white list format is shown in Table 1.

Table 1 For a CSGNAME used only within one PLMN, only the user needs to register with the operator of the PLMN. Correspondingly, the CSGNAME can be expressed as: CSGNAME.PLMNY.COM , where PLMNY is the top-level name of the CSGNAME obtained by the operator. . PLMNY assigns a closed subscriber group identity number to the CSG.

202. The terminal receives the closed user group identity identification number broadcast by the home base station, and is used for closing. The corresponding closed user group indicator is found in the household group white list.

203. The terminal receives the home base station name broadcast by the home base station, and displays the same at the local terminal together with the closed user group indicator. In another embodiment of the present invention, some mobile services may require the terminal to know the home base station name, and the method for the terminal side to identify the access network further includes: the base station sends the name of the home base station to the terminal, for example, the base station passes the cell. The form of the broadcast is sent to the terminal. For example, the home base station name includes a public land mobile telephone network identifier, a normal closed user group name, and a home base station identification name, and may be a character string that is freely defined within a length of 32 characters. The home base station name may be defined by the owner of the home base station, or may be configured by the operator, and broadcasted on the air interface. If combined with the closed user group name, the home base station identification name for broadcasting and the possession of the family may be displayed at the user terminal. The base station owner name, for example, the user terminal is displayed as CSGNAME.[PLMN X].COM@HNB Z or [PLMN X].CSGNAME.COM@HNB Z, indicating that the broadcast received by the user is the home base station whose home base station identifier is HNB Z. Issued, the organization that owns the HNB is CSGNAME.[PLMN X].COM or [PLMN X].CSGNAME.COM.

204. When leaving a closed user group, the terminal deletes the closed user group identity number of the closed user group and the closed user group corresponding to the closed user group identity number in the closed user group white list. Group indicator.

In the embodiment of the method for identifying the access network by the terminal side of the present invention, the terminal presets the closed user group indicator corresponding to the user group identity identification number in the local machine. After entering the coverage of a home base station, according to the closed user group identity number broadcast by the home base station, the corresponding closed user group indicator is found in the closed user group white list, thereby performing the closed user group Identification. The following describes an embodiment of a method for identifying an access network by the core network of the present invention, where the embodiment is Established on the identified access network structure of FIG. An embodiment of the method for identifying the access network by the core network of the present invention, as shown in FIG. 3, is mainly as follows.

301. The receiving terminal joins a request to close the user group.

302. Send the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number to the terminal. In another embodiment of the present invention, after the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number are sent to the terminal, the core network identifies the access. The method of the network also includes the following, as shown in FIG.

401. The service server pushes the closed subscriber group identity identification number list to the operator primary subscription server, or the primary subscription server obtains a closed user group identity identification number list from the service server. For example, the service server is a server for managing closed user group subscriptions, for example, may be an independent database server, or may be a server integrated with the primary subscription server, and a mobility management entity, a closed user group administrator, The primary subscription server has a connection interface.

For example, a mobility management entity (MME) is a network entity used to manage mobility contexts, bearer contexts, and access control of mobile users. For example, the Home Subscriber Server (HSS) is a network entity and database used to store mobile subscriber subscription information and network configuration information.

402. If the terminal enters the coverage area of the home base station, the mobility management entity obtains the user subscription information from the primary subscription server.

403. The primary subscription server sends the public land mobile list subscribed by the user of the primary subscription server to the mobility management entity according to the location of the terminal or the public land mobile phone network name or identifier supported by the mobility management entity. In another embodiment of the present invention, after the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number are sent to the terminal, the core network identifies the access. The method of the network also includes the following, as shown in FIG. 5.

501. The service server pushes a list of closed user group names to the operator primary subscription server, or the primary subscription server obtains a closed user group identity identification number list from the service server.

502. If the terminal enters the coverage area of the home base station, the mobility management entity acquires the user subscription information from the primary subscription server.

503. The primary subscription server selects, according to the location of the user terminal or the PLMN ID supported by the mobility management entity, a closed user group identity identification number list that can be used by the user subscribed to the primary subscription server as a closed user group whitelist. Give mobility management entities.

Optionally, if the service server pushes the closed user group name list to the operator main subscription server, the primary subscription server may first obtain an identity corresponding to the closed user group name through an internal or external query before performing the foregoing selection. a number, thereby obtaining a closed user group identity number list corresponding to the closed user group name list; the primary subscription server may also select a closed user group name that can be used in the PLMN subscribed by the user of the primary subscription server.

Mobility management entity.

In another embodiment of the present invention, after the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number are sent to the terminal, the core network identifies the access. The method of the network also includes the following, as shown in FIG. 6.

601. If the user terminal enters an area where the visited network has a home base station coverage area or a closed user group is available, the mobility management entity acquires the user subscription information from the primary subscription server to which the user terminal belongs. 602. If the PLMN where the primary subscription server is located does not support the closed subscriber group function, the mobility management entity acquires the temporary subscription information of the user visited from the visited PLMN primary subscription server.

603. Visiting place The PLMN main signing server sends the closed user group identity number white list of the visited user terminal to the mobility management entity. In another embodiment of the present invention, after the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number are sent to the terminal, the core network identifies the access. The method of the network also includes the following, as shown in FIG.

701. If the terminal enters the visited network, the home base station coverage area or the area where the closed user group is available, the mobility management entity or the visited landlord subscription server or the home landlord subscription server requests the closed user group of the user terminal from the service server by using the user number. Signing information. For example, the subscriber number may be an identifier in the mobile network, such as a subscriber ISDN number stored in the primary subscription server, the mobility management entity, or the terminal, or an IP multimedia system subscriber number.

702. The service server sends the subscriber number and the closed subscriber group subscription information to the requesting party. For example, considering that the service server may only have the user number and the closed user group subscription information, the mobility management entity or the visited landlord subscription server or the home landlord subscription server requests the closed authentication user group subscription information of the user terminal from the service server by using the user number. At the same time, the sender establishes a correspondence between the user number and the permanent identification number of the user. For example, the service server sends the user number and the closed user group subscription information to the requesting party, and the requesting party searches for the permanent identification number of the user corresponding to the closed user group subscription information according to the correspondence between the user number and the permanent identification number of the user. The sender has complete user information. In another embodiment of the present invention, after the identity number of the closed user group and the closed user group indicator corresponding to the closed user group identity number are sent to the terminal, the core network identifies the access. The method of the network also includes the following, as shown in FIG. 801. The service server receives a request to join the terminal to the closed user group.

802. The service server generates a sequence code, binds the sequence code to the user number added to the closed user group, and sends the sequence code and the closed user group information added by the user to the terminal.

803. The service server pushes the sequence code and the subscription information of the closed subscriber group information that the user joins to the primary subscription server (for example, the homeowner subscription server or the visited landlord subscription server) or the mobility management entity. After the mobility management entity or the primary subscription server (for example, the home primary subscription server or the visited primary subscription server) requests the subscription information from the service server, the primary subscription server sends the user closed subscriber group subscription information to the requesting entity.

804. The user terminal enters a closed user group coverage area, requests access to the mobility management entity, and sends a closed user group access sequence code.

805. The mobility management entity performs access control on the user according to the closed user group sequence code and the user subscription information. An embodiment of the method for the home base station of the present invention to identify an access network, as shown in Figure 9, is mainly as follows.

901. Broadcast the identity identification number of the closed user group supported by the home base station to the local cell.

Another embodiment of the method for the home base station of the present invention to identify an access network, as shown in FIG. 10, is mainly as follows.

1001. Broadcast the identity identification number of the closed user group supported by the home base station to the local cell.

1002. Broadcast the name of the home base station to the local cell. In the embodiment of the method for identifying the access network by the core network and the home base station side of the present invention, The identity number of the closed subscriber group is sent by the core network to the terminal, and a closed subscriber group indicator corresponding to the closed subscriber group identity number. Then, after the terminal enters the coverage of the home base station, the closed base station identity number is broadcast by the home base station, and the terminal finds a corresponding closed user group indicator in the closed user group white list, thereby Identify. The above embodiment of the method for identifying an access network of the present invention adopts a scheme different from the prior art. The existing home base station broadcasts the closed user group indicator while broadcasting the closed user group identity number. Since the existing home base station can only broadcast one closed user group name, the existing solution will close the user group. The group name is unified with the name of the home base station, and the unified name is broadcast to the cell. However, when a home base station supports multiple closed user groups at the same time, the multiple closed user group names are represented by the same home base station name, so that the user cannot identify each closed user group, and the home base station cannot be used. The name is distinguished from the closed user group name. The embodiment of the present invention keeps the identity identification number of the closed user group in the closed user group white list of the existing terminal, and the closed user group indicator corresponding to the closed user group identity identification number, and the home base station only broadcasts the closed The identity of the user group (optionally, the name of the home base station can also be broadcast), the terminal receives the correspondence between the identity indicator group indicator of the closed user group, and finds the closed user group indicator. The identification of the closed user group is completed. In another embodiment of the present invention, as shown in FIG. 11, a method of identifying an access network may be as follows.

1101. The closed user group administrator applies for closing the user group identity number number to the operator (for example, the service server) through the terminal, registers the closed user group name, and can apply for registration of the graphic identifier. For example, the closed user group may be a corporate or cross-regional organization, or may be similar A small closed user group for home users. This embodiment does not limit the specific process and method for applying for registration. For example, the method for short message registration can be used, and the closed user group requester sends the registration request short message to the operator registration server on the network side. The authentication server performs authentication authentication, and sends a reply short message to the requester that authenticates the authentication, and the content is the name and identity identification number assigned to the closed user group. The closed user group graphic identifier is also bound in the operator organization with the closed user group identification number number and the registered closed user group name in the operator organization. For a generalized closed user group name, it may be a closed user group name or a graphic, or each closed user group identification number may correspond to a different graphic.

1102. The closed user group administrator (for example, through the service server) invites the user terminal, after the user terminal accepts, or the user terminal (for example, through the service server) applies to join the closed user group, closes the user group administrator, and the business server will The whitelist is updated to the user terminal, and the user terminal keeps the identity number of the closed user group in the closed user group white list of the local device,

The process in which the user terminal is actually invited to join the user organization to close the user group, and the process of closing the user group white list to keep the closed user group identity number and the closed user group indicator may be different through service, mobile network signaling, etc. the way. For example, if a user organization registers a closed user group with multiple operators, the operator organization may provide all information about the user organization to help the user join all or part of the closed user group of the user organization to the closed user group white. List, if the closed user group identification number of the user organization, the closed user group name is only registered and used in one operator PLMN, the participation of the operator organization is not required, and only the user needs to perform.

1103. The user terminal enters a coverage range of the home base station of the closed user group, receives a closed user group identity number broadcast by the home base station, and finds a corresponding closed user group indicator in the local closed user group white list. . For example, the user terminal can select a closed user group to access by an automatic selection mode or a manual selection mode.

This embodiment implements identification of each closed user group by the user terminal. An embodiment of the terminal of the present invention, as shown in FIG. 12, includes: an obtaining unit 1201: for receiving a closed user group identity number broadcast by a home base station, and finding a corresponding closed user group in a closed user group white list An indicator, the closed user group white list includes the identity of the closed user group
