1. A method for session binding, comprising:
- a Policy and Charging Rules Function (PCRF) or a Broadband Policy Control Function (BPCF) receiving a first session from a fixed network, wherein the first session carries an IP address and a port number set;
the PCRF or BPCF receiving a second session from an Application Function (AF) or a Traffic Detection Function (TDF), wherein the second session carries an IP address and port number information; and
the PCRF or BPCF binding the first session to the second session according to the IP addresses and the port number information;
wherein after the PCRF or BPCF binding the first session to the second session, the method further comprises;
the PCRF or BPCF making a policy for a service according to an association relationship between the first session and the second session, and issuing the policy.

Abstract
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.
