Method and system for detecting service quality in next generation network

Abstract

The present invention provides service quality testing method and system in next generation network, said next generation network including network management facility, media gateway controller connected with said network management facility, and media gateway connected with said media gateway controller. Said method includes A, network management facility down sending test command to media gateway controller; B, media gateway controller according to said test command down sending testing control instruction to participated test media gateway, controlling participated media gateway establishing test channel; C, participated test media gateway through said test channel mutually transmitting / receiving test traffic stream, collecting service mass parameter, and reporting said service mass parameter to media gateway controller; D, media gateway controller reporting said service mass parameter to network management facility, network management facility to make processing to test result. The present invention can reflect practical network bearing quality.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method and a system for actively testing the service quality carried by the network in the next generation network. Background technique [0002] Next Generation Network (NGN) is a new network that integrates voice, data, fax and video services. It is a service convergence network that provides multiple services such as fixed mobile voice, data and video services based on the packet network. . Taking the voice service as an example, in the NGN system with the IP network as the core bearer network, the IP packets of the voice service are transmitted in the IP network in a best-effort manner, so the measurement of the network bearer service quality becomes a very important skills requirement. [0003] Currently, methods for testing the quality of service (Quality of Service, QOS) of the bearer network include active testing (or intrusive testing) and passive testing (or no...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a test method for service quality in the next generation network, aiming to solve the problem that in the active test of service quality in the prior art, the test service flow cannot truly reflect the network bearer quality status of the actual service flow, resulting in Inaccurate test results and high implementation costs
