Abstract

The invention discloses a method and system for session binding, which relates to the technical field of communication networks, and solves the problem that the terminal session signaling cannot be addressed to the PCRF through the backup DRA with different private synchronization interfaces, which causes the PCC policy to be unable to be issued. . The method includes: PCEF sends a session creation request to vDRA, and the session creation request includes at least the terminal's IP address, Session ID, and terminal identification; vDRA determines the first PCRF identification corresponding to the terminal identification; vDRA stores the terminal identification, IP address, and Session ID , sending the session creation request to the first PCRF; the first PCRF sends a session creation response to vDRA, and the session creation response includes at least the first PCRF identifier; vDRA sends a session binding data creation request to vSBDB, and the session binding data creation request includes Session binding information, where the session binding information includes a terminal identifier, an IP address, a Session ID, and a first PCRF identifier; the vSBDB stores the session binding information. The solution provided by the present invention is suitable for use in session binding.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a session binding method and system. Background technique [0002] Using the policy and charging control (Policy and Charging Control, hereinafter referred to as PCC) architecture, charging control and policy control based on service flow can be realized. In the PCC architecture, the Policy and Charging Rules Function (Policy and Charging Rules Function, hereinafter referred to as PCRF) sends the PCC policy to the Policy and Charging Enforcement Function (Policy and Charging Enforcement Function, hereinafter referred to as PCEF), so that the PCEF Accounting and corresponding control are performed on terminal services according to issued PCC policies. [0003] In order to ensure the correct delivery and execution of the PCC policy, it is necessary to route different PCC session signaling of the same terminal to the same PCRF. In the solution of the prior a...
