Embodiment Construction

[0025] In view of the defects of the prior art, the method for determining the codec type of the present invention proposes a processing method that can select the corresponding preferred codec type for a call according to the change of link quality. The main implementation principles and the principles of the present invention will be described below in conjunction with the various drawings. The specific embodiments are described in detail.

[0026] The method of the invention is suitable for selecting the coding and decoding types for various types of calls issued by the media gateway in the NGN system.

[0027] figure 1 Shown is the flow chart for determining the preferred codec type of the present invention, and its main implementation process is as follows:

[0028] Step S1. Office directions are generated. Office directions are the IP connection paths between MG and other gateways, or the common connection paths between MG and all terminals under the same IP network segmen...

Abstract

The invention relates to a method for confirming the decode / code type, for confirming the service quality based on the change of chain quality; via selecting right decode / code type, wherein the invention sends sample call to check the junction chain quality of media gateway, to judge the change of chain quality of said junction, and fix relative decode / code type for the call sent on said junction, to realize high service quality; when the chain quality decreases, the service quality can be confirmed.

Description

Technical field [0001] The present invention relates to next-generation network technology, in particular to a method for determining codec types in the next-generation network. Background technique [0002] The Next Generation Network (NGN, Next Generation Network) system is a service convergence network that uses an IP network as a carrier to provide fixed and mobile voice, data, and video services. Its basic feature is the separation of control, bearing and business. [0003] In the NGN system, the traditional switch is separated into two network elements: MGC (Media Gateway Controller, Media Gateway Controller) and MG (Media Gateway, Media Gateway). MGC is mainly used to complete the functions of the call control layer; while MG is mainly used to complete the media stream processing and bearer processing functions. The MG can convert different types of access signals into those suitable for transmission on the IP (Internet Protocol) network. RTP / RTCP (Real Time Protocol / Real ...
