Problems solved by technology

However, the existing technologies generally have the following defects: when a device or a link fails in the Diameter signaling network, the routing efficiency of the DRA is affected
Usually, the processing overhead of the Diameter signaling network is proportional to the number of routing hops, and the message delay is inversely proportional to the number of routing hops; therefore, in this scenario, compared with the optimal routing scheme, the end-to-end Message processing overhead and message delay are 20% higher, and efficiency is greatly affected

Embodiment Construction

[0064] The first embodiment of a Diameter signaling network routing method provided by the present invention is applied to a Diameter signaling network, such as figure 1 As shown, the method includes:

[0065] Step 101, the first DRA obtains the real-time status information of the second DRA and the link in the adjacent area;

[0066] It is not difficult to understand that the real-time status information includes DRA status information and link status information. A DRA may also be referred to as a node herein.

[0067] Here, the first DRA acquiring the real-time status information of the second DRA and the link in the adjacent area includes:

[0068] The first DRA acquires the real-time status information of the second DRA and the link in the adjacent area through Diameter layer message detection.

[0069] In a practical application, the acquisition by the first DRA of the second DRA of the adjacent area and the real-time status information of the link may also include: ...

Abstract

The invention discloses a Diameter signaling network routing method and device. The method comprises the steps of acquiring real-time status information of a second DRA (Diameter Routing Agent) and a link of an adjacent region by a first DRA; determining a dynamic topology structure of a Diameter signaling network according to the real-time status information; obtaining a dynamic routing configuration according to the dynamic topology structure and a preset routing configuration; and performing Diameter signaling message routing according to the dynamic routing configuration.

Description

technical field [0001] The invention relates to communication technology, in particular to a Diameter signaling network routing method and device. Background technique [0002] Based on the need to transmit Diameter signaling between network devices such as EPC, PCC, IMS, and service platforms, the LTE network introduces a Diameter signaling network composed of Diameter nodes and links. Nodes in the Diameter signaling network include a Diameter server, a Diameter client, and a Diameter Routing Agent (Diameter Routing Agent, DRA). The network accesses the Diameter server to use the applications and services provided by it, and the DRA transmits and processes Diameter signaling between the Diameter server and the client. Diameter nodes are connected by Diameter links based on SCTP / TCP transport layer protocol and Diameter application layer protocol to form a Diameter signaling network. [0003] In the Diameter signaling network, DRA needs to pre-configure the routing table t...
