Problems solved by technology
In fact, many gateways currently provide service level classification functions at the RTP service flow egress. Therefore, for a bearer network that supports differential service processing, the unclassified test service flow and the classified actual service flow actually take different routes. The business flow cannot reflect the working conditions of the actual business flow
[0006] In addition, this solution needs to build an additional test network, requires external test equipment or instruments, and a control center, which is expensive and especially inconvenient for testing in different places

Embodiment Construction
[0025] figure 2 It is a schematic diagram of the active testing method of the IP bearer network of the present invention. The test networking of the present invention is shown in the figure, the built-in test modules in the gateways A and B assign a virtual test terminal identifier TerminalID, and the gateways A and B establish one or more voice lines under the control of the softswitch Test service flow, conduct voice quality active test, fully simulate the actual service flow, make the routing path of the test service flow and the actual service flow in the IP bearer network exactly the same, and the test service flow truly reflects the actual service flow through the network situation. The built-in test modules of gateways A and B send and receive test voice streams to each other through the established test channel, and extract QOS parameters such as delay, packet loss, and jitter from the RTP voice service channel. The softswitch regularly issues QOS audit commands, ex...

This invention relates to a system and a method for carrying out QOS quality test in a NGN network characterizing in building-in a test and analysis statistic module and setting up a phone test service flow by the control of soft switch to obtain a real quality result of the IP load network in actual operation, in which, the step of setting up phone test service flow by the control of soft switch is to set up a test channel and transmit service flows mutually between the built-in analysis statistic modules to make the routes of the service flow and the actual service flow on the IP loading network the same to realize quick test of the QOS quality of the NGN network..
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a system and a method for testing the QOS status of the bearer network in an NGN system with an IP network as the core bearer network. Background technique [0002] In the next-generation network NGN system with IP network as the core bearer network, voice services are carried in IP packets, and IP packets are propagated in the network in a best-effort manner, so the QOS (Quality of Service) status of IP networks It determines the quality of the voice service and becomes a very important point to measure the NGN network. [0003] At present, there are two methods for testing the QOS status of the bearer network. One is active testing, that is, intrusive testing. The QOS quality of the network; another type of passive test, that is, non-intrusive test, tests and analyzes the existing voice service flow and obtains data. [0004] Existing active test methods for IP bearer n...
