A policy control method for a converged network comprises: in a roaming scenario, after learning that a user equipment (UE) accesses a mobile network through a wireless local area network (WLAN), a visited policy and charging rules function (V-PCRF) creating a subsession serving WLAN Offload when establishing an S9 session with a home policy and charging rules function (H-PCRF), and carrying a WLAN Offload instruction. The present invention can distinguish WLAN offload data in a roaming scenario from data routed back to an EPC network, so as to deliver policy control for the WLAN offload data. |
