A method for processing Traffic Detection Function (TDF) session and a Policy and Charging Rules Function (PCRF) are provided. The method includes: the PCRF links a first TDF session related with a proxy mobile Internet Protocol version 4 (IPv4) address and a second TDF session related with a first proxy mobile Internet Protocol version 6 (IPv6) address to a same IP Connectivity Access Network (IP-CAN) session; when the IPv4 address of the IP-CAN session is released, the PCRF requests the TDF to terminate the first TDF session. According to the invention, the problem in the relevant technology that the PCRF formulates a wrong policy because the IPv4 address is released only and the TDF session related with the IPv4 address is not terminated when the IPv4 address of the IP-CAN session is released is solved. By terminating the TDF session associated with the IPv4 address at the same time that the address is released, the resource utilization ratio is improved and the working efficiency of a system is improved. |
