<p>An accounting method for the session releasing of an Ultra Mobile Broadband access network is provided. In the case of the existence of a preferred Proxy Mobile IP tunnel, when a service Evolved Base Station, which serves the Access Terminal, sends a session releasing message to decide to release the Ultra Mobile Broadband session, or a session releasing message from the Session Reference Network Controller is received, the following steps are performed: S402, the service Evolved Base Station releases the resource allocated to the Access Terminal, and sends a corresponding accounting request message of the wireless resource occupied by the Access Terminal to an Access Gateway serving the Access Terminal; S404, after receiving the accounting request message, the Access Gateway sends an accounting response message to the service Evolved Base Station to confirm that the accounting request message is received by itself.</p> |
