An online charging model using the signaling procedure optimization in packet switching mobile network

摘要

An online charging signaling procedure in packet switching system is analysed. Appropriate parameters can be selected in order to reduce the number of account operation and amount of signaling by omitting some credit reauthorization process. An online charging model is proposed by using the signaling procedure optimization. In the model, session based charging function is divided into six closely linked modules. Before responding to the reauthorization request caused by the change of Quality of Service, the session based charging function extracts the useful information from the request information, and then looks up a table to calculate and select the optimal charging method.
