Embodiment 1
[0142] Figure 8 is a flow chart of PCRF initiating network flow migration according to this embodiment, such as Figure 8 As shown, the process includes the following steps:
[0143] In step S801, the PCRF receives a trigger and decides to initiate flow migration. The triggering includes that the PCRF receives new service request information from the AF, formulates a PCC strategy, and determines the access network for new service transmission. Or the PCRF needs to adjust the access network through which the ongoing service is transmitted according to reasons such as network load, subscription change, or network policy change.
[0144]In step S802, the PCRF sends a PCC Rule and an allowed access type to the PCEF through a policy and charging rule provision message. Allowed access network type identification, when the PCEF detects the service data flow identified by the PCC Rule, these service data flows will be sent to the access network indicated by the allowed access type...
