METHOD FOR SWITCHING SESSION BINDING ACROSS NETWORK AND WIMAX-CONNECTED SERVICE NETWORK

摘要

A method for switching session binding across network is provided. The method includes that: when a terminal accesses a network initially, the agent network element in the home network sends a message to the Authentication, Authorization and Accounting (AAA) server for updating the home network agent address after receiving an agent binding update message, and said AAA server records the home network agent address for the current session (201); when said terminal accesses the network by switching, said AAA server obtains the home network agent address for the current session, and returns it to the access gateway function network element during the process of access authentication and authorization (202). The method for switching session binding across network and the WiMAX-connected service network ensure the continuity of user services.
