Admission control system and admission control method in load supporting interface of communication network

Abstract

The system thereof comprises a communication control module and one or more multi media processing modules connected to the said communication control module through management control interface. The multi media processing module comprises a packet transceiver and a congestion detection module. The communication module comprises a congestion state management module and a calibration operation module. The method thereof includes: determining the traffic flow direction required by the communication service; accessing the congestion management module to get the congestion state information about the traffic flow; in term of predetermined strategy and congestion level information, executing, admitting or refusing the operation of communication service.

Description

technical field [0001] The invention relates to an admission control system and an admission control method, in particular to an admission control system and an admission control method for the congestion of a bearer interface in a next-generation communication network. Background technique [0002] The Next Generation Network (NGN) is a converged network that uses a packet communication network as the bearer and provides fixed and mobile services such as voice, data and video. NGN takes softswitch as the core technology, and its basic feature is the separation of control function and bearer function. [0003] see figure 1 , which is a schematic structural diagram of a packet communication network in the prior art. Among them, the main function of the media processing module is to be responsible for the bearer business of the media stream, and the main function of the communication control module is to implement connection control, translation and routing, gateway manageme...

AI Technical Summary

Problems solved by technology

[0015] 1. When the soft switch node itself is not overloaded, but the flow direction of the MGW connected to the soft switch connected to the IP network is congested, at this time, because the soft switch node is not yet overloaded, it cannot accept the call of the flow direction control

[0016] 2. When the MGW node itself is not overloaded, but a certain flow direction of the MGW access to the IP network is congested, at this time, the MGW cannot notify the softswitch to perform admission control on the call of the flow direction

[0022] Therefore, admission control to control interface congestion cannot replace admission control for bearer interface congestion
