Abstract
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.
