摘要

In 3GPP Release 6, the IP-based Online Charging System (OCS) is defined to support online charging for General Packet Radio Service (GPRS) and IP Multimedia core network Subsystem (IMS) services. During an online charging GPRS session, a number of mid-session events, such as Quality of Service (QoS) could dynamically affect the rating of the in-progress service. When such events occur, the GPRS support node needs to re-authorize the granted credit units with the OCS. If the change of QoS occurs frequently,the signaling load incurred by the re-authorization procedure increases heavily. In this paper, we propose a threshold-based scheme with parameter to reduce the traffic signaling for credit reauthorization procedure. By selecting an appropriate value, our study indicates that the signaling overhead in the OCS can be significantlyreduced while the inaccuracy of the credit informationinsignificantly increases. Based on our model, the mobile operator can choose appropriate parameter values in the threshold-based scheme for various traffic conditions.
