Monitoring method for wireless network call monitoring device based on distributed architecture

Abstract

A monitoring method based on a wireless network telephone monitoring device with a distributed structure relates to a voice monitoring system, in particular to a telephone monitoring system based on a wireless network with the distributed structure and a method of realizing the same. The telephone monitoring system includes a plurality of sniffer terminal modules(103) and a long-distance monitoring center module(108), wherein the long-distance monitoring center module(103) is connected with a plurality of sniffer terminal modules(108) through a wired / wireless link, and the long-distance monitoring center module(103) receives the captured VoWLAN data transmitted by the sniffer terminal modules(108), while the sniffer terminal modules(108) is long-distance controlled by the long-distance monitoring center module(103). The present invention realizes the professional VoWLAN monitoring for original voice monitoring. The device locates an embedded monitoring equipment within the range of a wireless lan according to the transfer characteristics of signals diverging in a wireless network, and the only marked address of a wireless network card(MAC Address) acts as the unique identification of a VoWLAN user. The media data is transmitted to the monitoring center to be analyzed and restored thus realizing the voice monitoring.

Description

technical field [0001] The invention relates to a voice monitoring system, in particular to a wireless network phone monitoring system based on a distributed architecture and an implementation method thereof. The invention belongs to the technical field of wireless networks. Background technique [0002] In recent years, with the continuous development of communication technology, voice communication via packet network has become the choice of more and more people. The packet network can not only support the transmission of the original voice service, but also better support the emerging multimedia service, and the transmission of data through the Internet can reduce the cost of the original high circuit switching network. Therefore, in the future, the packet network communication service has a great potential. Huge prospect. The most important thing in the packet service is to carry the voice service through the Internet, commonly known as VOIP (Voice Over Internet Protoco...

AI Technical Summary

Problems solved by technology

Traditional voice monitoring equipment cannot monitor the voice data in the IP network, and some existing VOIP monitoring devices monitor and intercept the voice data in the wired network, but cannot intercept the voice data of the wireless network, so VoWLAN services cannot be carried out. effective monitoring

At present, no patent documents related to the implementation method of the listening device specifically for VoWLAN have been retrieved.
