Method for signaling forwarding and signaling switching device

Abstract

The invention discloses a method for signaling forwarding and signaling switching device, which can improve the forwarding efficiency and support a plurality of route selection modes. The method includes: allocating a unique local direction identification to each local direction at IP signalling switching points; configuring route selection identification for each local direction according to the route selection mode, and recording routing information from IP signalling switching points to each local direction under different route selection modes; routing according to the seventh signalling source local direction route selection identification and objective local direction identification, and forwarding the signaling, when the IP signalling switching points forward a seventh signaling.

Description

technical field [0001] The invention relates to the technical field of SoftSwitch, in particular to a method and a device for forwarding signaling by an IP signaling transfer point. Background technique [0002] With the rapid development of IP network applications, NGN (Next Generation Network) based on IP bearer network and softswitch technology has been widely considered to be the general trend to realize the integration of three networks. [0003] The softswitch, that is, the Media Gateway Controller MGC (Media Gateway Controller), is responsible for call control, that is, the establishment, monitoring and teardown of call connections. Its function is equivalent to the function completed by the call processing module in the circuit switch. The soft switch is only responsible for signaling and call control, and has no transmission function. That is to say, the communication between two users only interacts with the soft switch through signaling (or protocol) when the cal...

Problems solved by technology

[0014] In-depth investigation and research on user needs found that in most cases, the routing method of the signaling transfer point is directly selected according to the destination signaling point code (DPC), accounting for about 80%. ), or according to the combination of source signaling point code (OPC) and destination signaling point code (DPC), there are also applications, but the percentage is small, only about 20%, but in some occasions it is true It is very necessary, but the current signaling transfer point can only support routing according to the code of the destination signaling point, and does not support other routing methods

[0015] In addition, for the AS routing selection on the IP side, the operator also has the requirement to set the priority level of the route. It is required to use the backup AS route when the main AS route is unavailable, but it is not currently possible.
