Method for realizing independent recording of internet protocol (IP) terminal in conference mode

Abstract

The invention discloses a method for realizing independent recording of an internet protocol (IP) terminal in a conference mode, relating to the field of data communication. According to the method for realizing independent recording of the IP terminal in the conference mode, the IP terminal independently triggers a recording process, establishes a media channel with recording equipment by use of a standard IP signal protocol, and directly sends media data of a recording target to the recording equipment. Through adoption of the method, intermediate steps are omitted, performance requirements and dependency on other equipment are lowered, the scheme cost is reduced, and the control flow is simplified; furthermore, due to use of the standard IP signal protocol, the networking flexibility is improved.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a recording method of a terminal device under an IP network environment. Background technique [0002] Recording is an important function of emergency, command and dispatch systems. It is used to record key information in the process of incident handling, so as to provide inspection basis and reference experience for future work. With the rapid development of IP networks and their applications, emergency response, command, and dispatch systems are also transitioning to IP environments. How to implement IP recording functions has become a topic of concern to the industry. [0003] At present, there are two commonly used methods for IP recording: one is to use the mirror port provided by the network switch to copy the media stream data and send it to the recording device; the other is to use the soft switch to control the IP terminal device, media server and recording ...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: ①The recording device needs to have the analysis function of the signaling protocol, which increases the design difficulty and requires high performance; ②The data of non-recording targets will also be copied and forwarded by the network switch, which is likely to cause processing congestion and packet loss, and Poor data security; ③The network switch must additionally have the function of port mirroring, which increases the cost of equipment during the implementation of the solution; ④The network switch needs to be deployed according to the location of the recording target, and the management is decentralized

This method has the following disadvantages: ① Deploying soft switches and media servers requires high equipment costs; ② There are private interfaces between devices, which has poor versatility; ③ It involves the establishment of media channels between IP terminals, media servers, and recording equipment, and the control process is complicated. ;④One recording occupies multiple media port resources in the media server, which requires high capacity and performance of the device
