METHOD, DEVICE AND SYSTEM FOR LOGGING-OUT WIMAX FEMTO ACCESS POINT (WFAP) FROM NETWORK OR DE-REGISTERING WFAP

摘要

A method, a device and a system for logging-out a WiMAX Femto Access Point (WFAP) from network or de-registering the WFAP are disclosed. The logging-out method comprises that: the WFAP performs a de-registration process with the Access Gateway (S11); the WFAP is de-authenticated through the Secure Gateway (SeGW) and the Authentication Authorization Accounting Server (AAA server) (S12); and the tunnel between the WFAP and the SeGW is detached (S13). The de-registering method comprises that: the WFAP receives a de-registration request message from the Access Gateway, wherein the de-registration request message includes the first identifier of the neighbor Base Station and/or the second identifier of other Access Gateway in addition to the above Access Gateway, guides the terminals served currently by the WFAP itself to switch to the neighbor Base Station corresponding to the first identifier and/or to register to the other Access Gateway corresponding to the second identifier, and transmits a de-registration response message to the Access Gateway. The device is a WFAP or an Access Gateway or a system comprised of both of them. The network resource can be saved, and the efficiency and the utilization to the network can be improved through the invention. Therefore, the communication continuity can be ensured.
