Abstract

The invention discloses a session association method and a system of a policy charging control PCC system in a mobile network. The method includes: the first network element initiates a first session request message including the IMSI information and / or IP address information of the user to the PCRF serving the user through the first DRA; the first DRA sends the IMSI information and / or IP address information, The identification information of the PCRF is sent to the DRA information synchronization module; the DRA information synchronization module stores the received information and its correspondence; the second network element initiates a second session request message to the second DRA; the second DRA utilizes the second session request message Inquire the IMSI information and / or IP address information in the DRA information synchronization module for the PCRF serving the user; the second DRA initiates a second session request message to the PCRF according to the returned PCRF identification information, so as to communicate between the PCRF and the second network element to establish a second session. Through the technical solution provided by the present invention, in the case of multi-DRA and multi-PCRF networking, the PCC system-based control for the same user can be correct and consistent.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a session association method and system of a PCC system in a mobile network. Background technique [0002] The Diameter protocol is adopted by the AAA working group of the Internet Engineering Task Force (IETF) as the next-generation AAA protocol standard. As a protocol family, the Diameter protocol includes the basic protocol (Diameter Base Protocol) and various application protocols extended from the basic protocol. The Diameter protocol is widely used in the policy and charging control (Policy and Charging Control, PCC) system architecture of the mobile network and the Long Term Evolution (Long Term Evolution, LTE) network and other networks. [0003] In the mobile network PCC system based on the Diameter protocol, the Diameter message routing agent (Diameter Routing Agent, DRA) is used to provide the message routing function of Diameter signaling, which can be used for Di...
