Communication network and method for charging and accounting

摘要

The present invention relates to a method and a communication network comprising a packet switched network part and a circuit switched network part and an interface between the packet switched network part and the circuit switched network part, wherein the circuit switched network part produces a call data record assigned to each call initiated and established from the circuit switched network part, said call initiating a session in the packet switched network part via the interface, wherein the packet switched network part generates a session data record assigned to said session and comprising session information being transferred from the packet switched network part to the circuit switched network part via the interface, and, within the circuit switched network part, means for adding the received session information to the call data record assigned to said initiated and established call, and means for charging and accounting the call on the basis of the call data record and said session information of the call data record. <IMAGE>
