Abstract
An accounting method for session release of an ultra mobile broadband access network is provided. In case of the existence of a preferred Proxy Mobile IP tunnel, when a serving Evolved Base Station, which serves the Access Terminal, sends a session release message to decide to release the Ultra Mobile Broadband session, or receives a session release message from a Session Reference Network Controller, the following steps are performed: S402, the serving Evolved Base Station releasing the resources allocated to the Access Terminal, and sending a corresponding accounting request message concerning the wireless resources occupied by the Access Terminal to an Access Gateway serving the Access Terminal; S404, after receiving the accounting request message, the Access Gateway sending an accounting response message to the serving Evolved Base Station to confirm its reception of the accounting request message.
