<p>The present invention provides a policy control method and system for accessing a fixed broadband access network. An FMC PF for sensing access of a UE to a fixed broadband access network is provided in a mobile network which a user requests to access currently. After receiving a trigger message from an ePDG, the FMC PF requests a BPCF to establish a policy session, and the BPCF performs policy control according to information about the fixed broadband access network currently accessed by the UE. It is known from the method of the present invention that when the UE accesses 3GPP through the fixed broadband access network, the FMC PF senses a gateway control session establishment request message or a DHCP request message from the ePDG, so that a PCRF of the 3GPP access network currently accessed by the UE is triggered to send a policy session request to the BPCF. In this way, in the case that the fixed broadband access network fails to sense the access of the UE or that the fixed broadband access network does not support 3GPP-based access authentication in the architecture of the prior art where the UE accesses a 3GPP core network through the fixed broadband access network, the QoS of the access of the UE is controlled, so as to provide QoS assurance to the entire data transmission path.</p> |
