Abstract: An accounting method for an ultra mobile broadband access network, wherein the method includes: S402, when a data binding point or access gateway AGW triggers a session reference network controller SRNC to initiate the paging to an access terminal AT, the SRNC sends an inter-ANRI signaling paging message to each evolved base station eBS in the paging area of the AT; S404, corresponding to a request from the SRNC, each eBS in the paging area of the AT performs the paging to the AT; S406, the eBS successfully paged an AT establishes the route between the eBS and the AT, creates the Air Link Record for the AT, and sends the accounting request (start) message related to the AT to the AGW serving the AT; and S408, after receiving the accounting request message, the AGW sends an accounting response message to the eBS successfully paged an AT to confirm that the AGW has received the accounting request message.
