Description
Technical field
The invention belongs to communication technical field, relate in particular to a kind of method and device of accessing user terminal to network.
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 or the like; 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 is provided is: the IP address assignment of MS, Internet insert, AAA proxy or server, based on the authorization control of terminal etc.
In order to realize the mobility restriction of terminal, in user's contract signing relationship, increase the mobility classification attribute, comprising: fixing, nomadic and mobile.Wherein, mobile service refers to terminal when moving with certain speed in the network side coverage, can use the data service of network continuously, the switching of network side support terminal, and in handoff procedure, guarantee the continuity of session; Nomadic business refers to terminal can be at different geographical position access networks, in the conversation procedure of data service, terminal is generally regularly attached to certain Access Network, when terminal moves to new position, need re-accessing network, carry out new data service session, therefore, nomadic professional user terminal can initiating equipment reattachment, but not necessarily need to guarantee the continuity of session; Fixed service refers to terminal can only carry out data service at the fixed area access network, when leaving this fixed area, and then can not access network.
For some operator of some countries,, therefore,, require to limit the mobility of its terminal for fixing and nomadic user because the restriction of licence plate can only be runed fixing or nomadic Network.
The inventor finds, in the prior art, in the accessing terminal to network process, can't know the mobility limitation information of network, so user terminal can't select suitable network to insert the networking of inconvenient terminal according to the requirement of self.
