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

Embodiment Construction

[0030] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0031] The flowchart of an embodiment of the routing agent method of the present invention is as figure 1 shown.

[0032] In step 101, the DRA acquires Rx session information.

[0033] In step 102, the DRA judges whether the user belongs to the local area. If the user belongs to the local area, execute step 103; if the user does not belong to the local area, execute step 104.

[0034] In step 103, the DRA determines the corresponding PCRF according to the user identifier and APN in the Rx session message, and routes the Rx session message to the PCRF, completing the flow of the routing agent method of the present invention.

[0035] In step 104, the DRA roams the Rx session message to the DRA in the user's home area. After receiving the Rx session message, the DRA in the user's home area will start to execute from ...

Abstract

The invention provides a routing agent method and node, which relate to the field of intelligent pipelines. Wherein, the routing proxy method of the present invention includes: the routing proxy node DRA obtains the Rx session message; the DRA judges whether the user is a user in this area according to the user identification in the Rx session message; Corresponding to the PCRF, and routing the Rx session message to the corresponding PCRF. Through such a method, the DRA can determine the PCRF to which the user belongs according to the user identifier and APN information in the obtained Rx session message, so as to send the Rx session message to the corresponding PCRF, so as to realize session binding.

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 standards, the interface based on the Diameter protocol in LTE adopts the DRA (Diameter Routing Agent, routing agent node) signaling network to perform 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 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, making roaming on the Rx interface more ...
