Embodiment Construction

[0051] Various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. First, examples of the present invention are given. see figure 1 ,

[0052] Step S101: in the voice data packet collected, obtain the data packet of User Datagram Protocol (UDP, User Datagram Protocol) odd port;

[0053]For the collection of high-traffic voice data, the acquisition board uses a Gigabit Ethernet card to collect voice data, and the collected voice data needs to be filtered and decoded to filter out irrelevant data, leaving only RTCP packets. Wherein, the process of filtering out the RTCP data packet needs to be judged comprehensively in combination with the characteristics of the data port and the characteristics of the protocol data packet header.

[0054] Since the RTCP data packet does not exist independently, it is transmitted together with the corresponding RTP data packet carrying voice data, and the RTCP data packet is us...

Abstract

The invention discloses a voice analyzing method and system and a voice collecting front-end device that are applied to the field of communication technology. The method of the invention comprises: the data packet of a UDP odd port is obtained in the collected voice data packet and a RTCP data packet is obtained by judging the version number and the message type of the data packet of the UDP odd port; the RTCP data packet is decoded to obtain a voice link damage index and an SSRC mark; a voice link corresponding to the RTCP data packet is confirmed by utilizing the port of the RTCP data packet and the SSRC mark; the voice link damage index is utilized to analyze the corresponding voice link. The invention provides a voice analyzing system and a voice collecting front-end device. When the invention carries out high flow voice data analyzing, the analyzing process is simple, fast and accurate.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a voice analysis method, system and voice collection front-end machine. Background technique [0002] Next Generation Network (NGN) is a milestone in the history of telecommunication, marking the arrival of a new generation of telecommunication network era. With the rapid development and application of softswitch technology in NGN, it has become an important goal of telecom operators to replace public switched telephone network (PSTN) based on time division multiplexing (TDM) by Internet protocol (IP) technology in softswitch technology. However, the voice service carried by IP technology brings new difficulties and challenges while providing advantages such as high bandwidth, high flexibility and service integration. Since the IP network itself provides a connectionless service based on a best-effort policy, how to ensure the quality of service (QoS) performance of servic...
