Method for policy and charging rules function (PCRF) informing centralized deployment functional architecture (BPCF) of user equipment access information

摘要

A system and method for performing quality of service control on a user equipment are provided in the present invention. The method includes: after establishing an Internet Key Exchange version 2 (IKEv2) security association between the user equipment and a packet data network gateway to establish an Internet Protocol Security (IPSec) tunnel, the packet data network gateway sending IPSec tunnel information to a Policy and Charging Rules Function (PCRF), the PCRF then sending the IPSec tunnel information to a Broadband Policy Control Function (BPCF), and the BPCF performing quality of service control on services of the user equipment according to the received IPSec tunnel information. With the technical scheme of the present invention, it enables the BPCF to acquire tunnel information of the user equipment and then perform quality of service control on the user equipment.
