Abstract:
1. A charging method for a terminal being accessed through multiple access networks, and said charging method comprising: when the terminal establishes one IP Connectivity Access Network (IP-CAN) session with a packet data network through a plurality of access networks simultaneously to transmit different data flows of one or more services, a charging subsystem knowing Multiple Access of said terminal from a Policy and Charging Rules Function (PCRF) through an Application Function (AF); the PCRF sending an IP-CAN Type parameter of each access network connection passed through by each data flow of the service accessed by said terminal and a corresponding flow identifier to the AF, wherein each data flow is identified by the corresponding flow identifier; said AF sending said IP-CAN Type parameter and said corresponding flow identifier to said charging subsystem, and said charging subsystem identifying the corresponding data flow according to the flow identifier, and charging differently for the data flows passing through different access network connections of said terminal according to corresponding IP-CAN Type parameters.
