US 8,570,912 B2 · Accounting method for ultra mobile broadband access network

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.

a serving Evolved Base Station (eBS), which serves an Assess Terminal (AT), releasing resources allocated to the AT when the serving eBS sends a session release message to release a UMB session, or receives a session release message from a Session Reference Netwerl Controller (SRNC) to release a UMB session, and when there exist multiple Proxy Mobile IP (PMIP) tunnels
the serving eBS sending an accounting request message concerning wireless resources occupied by the AT to an Access Gateway (AGW) serving the AT;
and
after receiving the accounting request message, the AGW sending an accounting response message to the serving eBS to confirm its reception of the accounting request message;
wherein
if there is an Air Link Record created for the AT in a non-serving eBS or DAP, the non-serving eBS sends an accounting request message to the AGW;
and
after receiving the accounting request message from the non-serving eBS, the AGW sends an accounting response message to the non-serving eBS so as to confirm its reception of the accounting request message from the non-serving eBS.
