Description
Technical field
The invention belongs to communication technical field, relate in particular to a kind of method and system of transferring service of universal service interface system.
Background technology
WiMAX (Worldwide Interoperability for Microwave Access, the microwave interoperability is inserted in the whole world) is a kind of wireless metropolitan area network technology based on the IEEE802.16 standard.WiMAX network wireless side is based on the wireless MAN access technology of IEEE802.16d/e standard, adopt OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexi) and OFDMA (OFDM Access, the OFDM access) physical-layer techniques, effectively anti-multipath decline.Under the optimum channel decline situation, transmission rate can be approached 75Mbps.
WiMAX cellular logic framework as shown in Figure 1, the whole network of WiMAX mainly is made up of following three parts:
(1) terminal: comprise SS (Subscriber Station, subscriber board) or MS (Mobile Station, travelling carriage), terminal is used this devices accessing WiMAX network.
(2) accessing business network: ASN (Access Service Network, accessing business network) is defined as the network function set that the WiMAX terminal provides the wireless access service.ASN has comprised BS (BaseStation, base station) and ASN-GW (ASN Gateway, ASN gateway) network element.Wherein the major function of BS network element is: provide the L2 of BS and MS to be connected, RRM etc.; The major function of ASN-GW network element is: for MS authentication function provides client functionality, provide for MS and switch in the Relay function (as IP address assignment), ASN of L3 information etc.
(3) connection service network: CSN (Connectivity Service Network connects service network) is defined as the WiMAX terminal provides IP Connection Service.CSN mainly comprises logic entities such as prepaid server and AAA server, and the major function that provides is: the IP address assignment of MS, Internet insert, AAA proxy or server, based on the authorization control of terminal etc.
Be accompanied by the open requirement of Network, also introduced a kind of business of WIMAX network can the opening in the WiMAX network and given in the net or the third party's application interface outside the net, i.e. USI (UniversalService Interface, general service interface).The WIMAX network can by the USI system provide business interface to Applications Service Provider (Application Service Provider, ASP)/internet, applications service provider (internet Application Service Provider, iASP).By calling the professional ability that USI provides, ASP or iASP can use the open business that accesses terminal at WiMAX, and by ASP network or the Internet can be convenient provide personalized service for WiMAX accesses terminal.The WiMAX network comprises QoS, location-based service, Multimedia Broadcast Multicast Service, end message inquiry, terminal authentication etc. by the professional ability of USI open system.
Fig. 2 is the network reference model of USI system.Wherein travelling carriage (MS), accessing business network (ASN) and be connected service network (CSN) and be three chief components of WiMAX network, and ASP/iASP is the application service provider who is independent of the WiMAX network.As shown in the figure, the USI system is arranged in CSN, and is undertaken alternately by U1 interface and ASP/iASP.The USI system can also be alternatively with CSN in aaa server, message server, location server etc. carry out mutual.The existing internet interface of mutual use (as the HTTP method) of MS and ASP/iASP.
The inventor finds, after not defining terminal in the existing protocol and roaming, how the USI system carried out calling service, therefore, can't realize the calling service of terminal USI system under roaming state in the prior art, influenced carrying out of business.
