Routing agent method and node

Abstract

The invention provides a routing agent method and a node, which relate to the field of intelligent pipelines. The routing agent method comprises steps: a diameter routing agent (DRA) acquires an Rx session message; the DRA judges whether the user is a local user according to a user identifier in the Rx session message; and if the user is the local user, a corresponding PCRF (Policy And Charging Rules Function) is acquired according to the user identifier and an APN (Access Point Name), and the Rx session message is routed to the corresponding PCRF. Through the above method, the DRA can determine a user ownership PCRF according to the user identifier and the APN information in the acquired Rx session message, the Rx session message can thus be sent to the corresponding PCRF, and session binding is thus realized conveniently.

Description

Technical field [0001] The invention relates to the field of intelligent pipelines, in particular to a routing agent method and node. Background technique [0002] According to the 3GPP series of standards, the Diameter protocol-based interface in LTE uses a DRA (Diameter Routing Agent, routing agent node) signaling network for addressing strategy and routing selection. The current Gx interface roaming technology has been supported by industry standards and has been commercialized, but the Rx interface roaming technology has not yet been supported by mature industry / enterprise standards. [0003] At the same time, the commercialization of LTE will be popular, and there will be multiple APN (Access Point Name, access point name) access scenarios (Internet, VoLTE, etc.). The increase in the number of 4G users will also require core network expansion. At that time, the same area, such as the provincial level In the administrative area, multiple sets of PCRF and PCEF scenarios will ap...

Problems solved by technology

The current Gx interface roaming technology has been supported by industry standards and has been commercialized, but the Rx interface roaming technology has no mature industry / enterprise standard support

[0003] At the same time, with the popularization of LTE commercialization, there will be multiple APN (Access Point Name, access point name) access scenarios (Internet, VoLTE, etc.), and the increase in the number of 4G users will also require core network expansion. In the administrative area, there will be multiple sets of PCRF and PCEF scenarios, which will increase the difficulty of roaming on the Rx interface
