COMMUNICATION NETWORK AND TERMINAL ACCESS METHOD IMPLEMENTED BASED ON WIMAX NETWORK FRAMEWORK

摘要

A communication network and terminal access method implemented based on WIMAX network framework are provided. The communication network includes an access service network and a connection service network in the WIMAX network framework. The access service network includes a base station and an access gateway, and the connect service network includes an Identity Location Core Route (ILCR). The communication network also includes a packet data network. The access gateway provides access service and control for the terminals, and maintains connection information between the terminal and the correspondent end, and cooperates with other access gateways to implement handover for the terminals across the access gateway and across the ILCR. The ILCR is used for maintaining session connection for the terminal, maintaining the mapping information between the terminal and the correspondent end, and implementing the routing and forwarding of the data message. The framework arrangement of the invention takes requirement of compatibility with the terminal and compatibility with the upper layer service, requirement of only upgrading the network side device, and compatibility with the application settings of not changing terminal into consideration.
