Method, device and system for session binding

摘要

Disclosed are a method, device and system for session binding. The method includes: a PCRF or BPCF receives a first session from a fixed network, wherein the first session carries an IP address and a port number set; the PCRF or BPCF receives a second session from an AF or a Traffic Detection Function (TDF), wherein the second session carries an IP address and port number information; and the PCRF or BPCF binds the first session to the second session according to the IP addresses and the port number information. The disclosure solves the problem of inaccurate session binding in the scenario where a mobile terminal directly accesses mobile network services via a fixed network.
