Abstract

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.

Method and W AX connection

Wood field

This involves interworking, especially with regard to switching methods and W connections.

Background

The global microwave access operation (W, Wo de ope North c owaVe Acces) is a 802.16 connection, effectively utilizing limited meta resources to provide larger air ports (up to 70 s capacity) and more coverage (up to 60 km) ). WF (eess Fde y, wood) is also a high-quality element, and it has been deployed in large numbers in offices, homes, and so on. However, WF works as a distance from wood, covering it (about 100), and can only work on other woods. If WF has low construction, deployment, etc., and W is built and covered, the investment cost will be very high. Therefore, WF and W will coexist in the same phase. Considering W, it can connect W-F to . W WF's interoperability will help, and users with large coverage can use different characteristics in different geographic parks.
