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.

Abstract

The monitoring method of the wireless network phone monitoring device based on a distributed architecture is a voice monitoring system, specifically a wireless network phone monitoring system based on a distributed structure and its implementation method, including: several sniffing terminal modules (103) And remote monitoring center module (108); Wherein: remote monitoring center module (103) is connected with several sniffing terminal modules (108) by wired / wireless link, remote monitoring center module (103) receives sniffing terminal module (108) ) to send the intercepted VoWLAN data, while remotely controlling the sniffing terminal module (108); realizing the professional VoWLAN monitoring of the original voice monitoring. According to the signal divergence transmission characteristics of the wireless network, this device places an embedded monitoring device within the range of the wireless LAN, and uses the uniquely marked address (MAC address) of the wireless network card as the unique identification of the VoWLAN user; by transmitting the media data to the monitoring center for analysis Restore to realize 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...
