Description

Method and device for registering general service interface system

TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for registering a general service interface system.

Background technique

WiMAX (Worldwide Interoperability for Microwave Access) is a wireless metropolitan area network technology based on the IEEE802.16 standard. The wireless side of the WiMAX network is a wireless metropolitan area network access technology based on the IEEE802.16d/e standard. The physical layer of OFDM (Orthogonal Frequency Division Multiplexing) and OFDMA (OFDM Access) are used. Technology, effective against multipath fading. In the case of optimal channel fading, the transmission rate can approach 75 Mbps.

WiMAX network logic architecture shown in Figure 1, WiMAX network consists of the following three parts: (1) Terminal: including SS (Subscriber Station, user station) or MS (Mobile Station, mobile station), the terminal uses the device to access WiMAX network.

(2) Access service network: ASN (Access Service Network) is defined as a set of network functions that provide wireless access services for WiMAX terminals. The ASN includes BS (Base Station) and ASN-GW (ASN Gateway) network elements. The main functions of the BS network element are: providing L2 connection between the BS and the MS, radio resource management, and the like; the main functions of the ASN-GW network element are: providing client functions for the MS authentication, authorization, and accounting functions, and providing the MS with Relay function of L3 information (such as IP address allocation), intra-ASN switching, etc.

(3) Connection service network: The CSN (Connectivity Service Network) is defined to provide IP connection services for WiMAX terminals. The CSN mainly includes logical entities including a prepaid server and an authentication, authorization, and accounting server. The main functions provided are: MS IP address allocation, Internet access, AAA proxy or server, terminal-based authorization control, and the like.

Along with the requirements of the opening of the network service, a WiMAX network has also introduced a third-party application interface that can open the service of the WIMAX network to the network or the network, that is, the USI (Universal Service Interface). The WIMAX network can provide a service interface to the Application Service Provider (ASP) / Internet Application Service Provider (iASP) through the USI system. By calling the service capabilities provided by USI, ASP or iASP can apply services open to WiMAX access terminals, and it can be more convenient for WiMAX access terminals through ASP network or Internet. Personalized service. The WiMAX network's open service capabilities through the USI system include QoS, location services, multicast broadcast services, terminal information query, terminal authentication, and the like.

Figure 2 shows the network reference model of the USI system. Among them, mobile station (MS), access service network (ASN) and connection service network (CSN) are the three main components of WiMAX network, and ASP/iASP is an application service provider independent of WiMAX network. As shown in the figure, the USI system is located in the CSN and interacts with ASP/iASP through the U1 interface. The USI system can also optionally interact with an AAA (Authentication Authorization Accounting) server, a message server, a location server, and the like in the CSN. MS interacts with ASP/iASP using existing Internet interfaces (such as the HTTP method).

The USI system interface between the network and the home network is a U5 interface, which is used to transmit USI information between the home network and the visited network, such as: USI information, USI application policy, USI charging policy, etc. In addition, the U5 interface is also used. The USI assisting the roaming area to register with the USI of the home network, and the USI service call initiated by the ASP from the visited place;

In the existing protocol, when the user roams from the home network to the visited network, if the user does not register with the USI system before, but the user wants to access the USI service while roaming, it needs to go to the USI system of the home network. USI registration. At this time, the USI system in the visited area may participate in the user's USI registration process, but only acts as a Proxy or Relay, and forwards the registration message.

The inventor found that the roaming scenario in the existing protocol is mainly for the scenario where the USI system is deployed for both the hometown and the visited network. In the following scenarios, when the terminal roams to the visited network, the USI system registration cannot be completed, and the USI system cannot be used. - 1. The user's home network does not have a USI system. When the terminal roams to the visited network with the USI system, the USI service of the visited network needs to be used; the USI system is an optional function for the WiMAX system;

2. The user's home network has a USI system, but the user does not have a USI registration in the home network. BP: There is no USI ID. When the terminal roams to a visited network, the USI service of the visited network needs to be used.

3. Both the user's hometown and the visited network have USI systems, but the visited network can provide services that the home network cannot provide; these services need to be used when the terminal roams to visit the network.

In some of the above scenarios, the user cannot register with the USI system on the visited network, which further leads to the inability to use the USI service of the visited network.
