Problems solved by technology

[0015] Although the commercial MGC has comprehensive functions and flexible control, the writing of test scripts is complicated, and it takes a lot of time to debug the scripts, which is inefficient, especially for the interoperability problems found during the operation of the equipment, which cannot be reproduced efficiently and quickly. and positioning

Embodiment Construction

[0057] The present invention is mainly aimed at the media gateway control protocol (MGCP and MEGACO / H.248 protocol) through specific commands in the message to create associations and real-time transport protocol RTP (Real-timeTransportProtocol) connection characteristics (MGCP is a CRCX command, MEGACO / H. 248 is an ADD command), by establishing an association relationship between the association created by CRCX and the ADD message in the call flow script and the RTP connection identifier and the physical endpoint and the RTP connection identifier that the media gateway MG (MediaGatway) has created in real time, when sending the message The dynamic protocol keywords are replaced, so as to complete the simulation process of the call control flow. (MGCP is the connection identifier Connection Id, MEGACO / H.248 is the temporary endpoint identifier Ephemeral Termination Id)

Abstract

The invention discloses a call control flow testing tool based on a media gateway control protocol. The tool is provided with an endpoint state table, a send message processing module and a received message processing module. The endpoint state table stores an original state variable and a real-time operation state variable of an endpoint, and updating is carried out through the send message processing module and the received message processing module. The invention discloses a testing method of the testing tool at the same time. Aiming at characteristics of the media gateway control protocol, through analysis processing of a small number of key variables in a call control message and a tested device real-time response message, a simulation test of a call control flow is completed. When compiling a test script, a tester only needs to organize a necessary call control message file and does not need to add an additional control parameter, the call control flow provided at site is directly converted into the test script for use, the workload of compiling and debugging the script is reduced, and work efficiency is greatly raised.

Description

technical field [0001] The invention relates to the technical field of electric communication, in particular to a call control flow simulation test tool and method based on a media gateway control protocol. Background technique [0002] With the development of broadband Internet, access network products supporting VoIP functions have been deployed in every corner of the world instead of traditional fixed telephone network access equipment, and at the same time provide broadband Internet access and voice services. As important VoIP signaling control protocols, the media gateway control protocol MGCP and MEGACO / H.248 are widely supported and used in operators' Softswitch (Softswitch) and IMS (IP Multimedia Subsystem) systems. Broadband access equipment has and The ability of Softswitch / IMS equipment on the existing network to perform VoIP protocol interconnection is often a network access requirement for operators. However, due to differences in the understanding and implemen...
