Description

 User identification card, mobile station, user 3-layer protocol information management method and system

Technical field

 The present invention relates to the field of mobile communications, and in particular, to a subscriber identity card, a mobile station, a user layer 3 protocol information management method and system.

Background technique

In current mobile communication specifications (for example, 3GPP TS 31.102 Characteristics of the Universal Subscriber Identity Module (USIM) application, YD/T 1762.1 TD-SCDMA/WCDMA digital cellular mobile communication network universal subscriber identity module and inter-terminal Cu interface technical requirements), The application and file structure are defined in the field of user identification module SIM/Universal Subscriber Identity Module USIM technology, wherein the application-specific dedicated file ADF is the access point of the basic data file EF and the proprietary file DF to which it belongs. The EF file containing the USIM service and network related information is located under the USIM ADF. It defines the EF _MSI (International Mobile Subscriber Identity), which contains the IMSI (International Mobile Subscriber Identity) information.

 There are 15 IMSIs, and their structure is as follows:

 MCC: Mobile Country Code, mobile country code, 3 digits, China is 460;

 MNC: Mobile Network Code, mobile network code, 2 or 3 digits, the user identifies the PLMN to which the user belongs.

 MSIN: Mobile Subscriber Identification Number: The user identifies a subscriber in a PLMN.

The IMSI can determine the phone number of the subscriber, but the USIM service and network related information does not contain the IP address. Currently, the gateway assigns an IP address to the subscriber, which is a continuous service of the mobile subscriber packet switching (PS) domain. Sex creates obstacles and increases the difficulty of security management/user traceability. In the prior art, an IP address has an ambiguity of identity and location. The IP address is used as the location identifier. The IP address represents the network segment where the terminal is located. The network segment is divided according to the physical location. It is the basis of packet routing. When the terminal location moves, the IP address must be changed. IP address as the identity, all kinds of applications are based on IP address establishment, IP changes, will lead to various applications connected Specifically, in the existing Packet Data Protocol (PDP) context activation process, the Gateway GPRS Support Node (GGSN) uses the Radius/Dynamic Host Configuration Protocol (DHCP). ) After dynamically requesting an IP address from the Radius/DHCP server, it is assigned to the user. This dynamic allocation of user addresses increases the complexity of user traceability/security management. Especially in the scenario where the mobile user accesses the intranet (intranet), the user address is not fixed, and the business process of authenticating, managing, and mapping the user identity is required. In addition, since the IP address of the user is not fixed, when the information is directed and pushed, the process is complicated, and it is necessary to find the location information and IP address information of the user.

In the embodiment of the present invention, the EF _{SL3I of the} user layer 3 protocol information is preset in the user identification card (such as the SIM/USIM card), and the bearer Capability information unit (Bearer Capability) The information element carries the user information layer 3 protocol. In the related protocol registration process, the related protocol registration network element processes the mechanism according to the user layer 3 protocol information. By carrying the Layer 3 protocol information of the user, the PS service consistency of the user can be further ensured, the PS service experience when the user roams is enhanced, and the complexity of the network configuration is reduced.

 The above mainly describes a case where the mobile station includes a detachable and replaceable storage function device, such as a mobile station such as a mobile phone, wherein the user identification card is a storage function device, and the user identification card stores the encrypted IP address and the like. Layer protocol information, and different user identification cards are bound to different IP addresses; for mobile stations without detachable storage devices, such as machine-in-one mobile phones, user 3-layer protocol information such as a hardened IP address can be stored.

The user layer 3 protocol information is information corresponding to the mobile station, so that the network side locks the mobile station according to the IP address in the user layer 3 protocol information, and maintains the service continuity of the mobile station.

In the present invention, when the related interface interacts, the bearer capability information unit carries the IP address bound by the mobile station, and when the mobile station roams, its IP address does not change, and the user uses the IP address to access the Internet service, that is, keeps The Internet service is in a fixed binding relationship with the user IP address. At this time, the IP address essentially has the identity attribute of the mobile station, and does not have a routing attribute. In order to ensure that packets can be correctly routed in the network, you need to combine other existing switching routing technologies, such as identity network and location information to separate the identification network, tunnel or VPN (Virtual Private Network).

The business continuity of the mobile station.

 As described above, the network side uses the IP address as the identity attribute of the mobile station, and uses other routing technologies, such as the identity network and the location information separated by the identification network, the tunnel or the VPN to ensure the correctness of the routing of the service packets.

 The transmission and processing of the user layer 3 protocol information will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Example 1

 The embodiment 1 is a basic packet radio service (GPRS) attached mobile station information flow (Attach MS Information Procedure) based on the 3GPP TS 23.060 protocol. In this process, the field in the embodiment of the present invention is added to the existing message, and the user is carried. Layer 3 protocol information, MS (Mobile station) reports the user's Layer 3 protocol information to the information management network element, such as the MSC/VLR (Mobile Switching Center/Visitor Location Register). The process shown in Figure 5:

 Step 501: The MSC/VLR sends a mobile station information request (MS Information Request) according to a normal procedure;

 Step 502: The SGSN (Servicing GPRS Support Node) sends an identity request ( Identity Request) to the MS;

In the mobile station attaching process, the mobile station is required to provide a P-TMSI packet-Temporary Mobile Subscriber Identity or an international mobile subscriber i (IMSI-International Mobile Subscriber Identity), and then the SGSN and the HLR (Home) Location Register), MSC/VLR and HLR need to exchange location update information. According to the embodiment of the present invention, since the IP address of the user is solidified and globally unique to the user country mobile identification code IMSI, and the user layer 3 protocol information such as the IP address carried by the user is used, the existing query operation can be reduced. Faster PDP session connection to establish PS domain.

 The mobile station (MS) in the above embodiments 1-3 refers to a mobile terminal (e.g., a mobile phone) equipped with a subscriber identity card.

 Example 4

 In the PDP Context Activation (PDP Context Activation) protocol of the 3GPP TS 29.061 protocol, the field in the embodiment of the present invention is added to the existing message, and the user layer 3 protocol information is carried.
