Abstract
The present invention discloses an accounting method in an IP multi-media subsystem network, which includes two steps. Firstly, when the trigger condition of accounting is satisfied, a unification network element constructs a message of unification accounting information, which is then sent to an accounting data processing function; and secondly, according to the received message of unification accounting information, the accounting data processing function constructs corresponding accounting telephone bills of each of the network elements contained in the unification network element or corresponding unification accounting bills of the unification network element. By providing a syncretic accounting method in the IP multi-media subsystem network, the present invention simplifies the accounting processing logic, and as a result, when the network elements on the control layer of the IP multi-media subsystem network are unified, the flow between the network elements and the accounting data processing function is greatly reduced.
