Method for detecting calling continuity of IP packet carrying network

Abstract

The invention discloses a calling through detection method of IP packet carrying network, used for the fault type judgment when calling failure, in which, the media gateway network interface unit sets the detection port, and through the first media gateway, continuously sending the user datagram protocol detection packet to the said detection port of the media gateway, and the said first media gateway gains the said user datagram protocol detection packet returned by the said media gateway, and then calculating the transmission parameters, and according to the said transmission parameters of the user datagram protocol detection packet to judge the fault type. The calling through detection method of IP packet carrying network in the invention timely processes the calling fault detection when detecting the call failure and it can accurately and effectively reflect the cause of the failure, and meanwhile, it can monitor the operation condition of the IP carrying network and media gatewaydevice when system abnormal, and facility the maintenance of NGN system for the operators.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for detecting call continuity test on an IP packet bearer network. Background technique [0002] A SoftSwitch (SoftSwitch) and a Media Gateway (Media Gateway, MG for short) are core devices in a Next Generation Network (Next Generation Network, NGN for short). Softswitch mainly completes call control, media gateway access control, resource allocation, protocol processing, routing, authentication, billing and other main functions, and provides users with basic voice services, multimedia services, mobile services and diversified third-party services; The media gateway implements the establishment, transmission and release of voice media streams under the control of the softswitch. [0003] Figure 1 shows the system network diagram of softswitches and media gateways in NGN. The softswitch controls the gateway to complete the calling process through the MEGACO (Media...

Problems solved by technology

[0006] In order to solve the problem that the network failure cannot be reflected in time in the prior art, and at the same time, it is impossible to completely cover all the IP packet bearer networks that all calls may reach and increase the burden on the IP bearer network, the purpose of the present invention is to provide an IP packet bearer network The call continuity detection method of the network, when the user is interrupted or unable to connect during the call, conduct a continuity test on the IP bearer network in time to accurately and real-time detect the operation of the network
