Encrypted media stream recording method and switching control device

Abstract

The invention provides a recording method of encrypted media streams and swapping control equipment. When the media streams which undergo encryption processing and are transmitted between a first terminal and a second terminal carrying out voice communication need to be recorded, a meeting is created through the swapping control equipment, and the first terminal, the second terminal and a recording server are connected with the created meeting so that the swapping control equipment can send the media streams of the first terminal and the media streams of the second terminals to the recording server, wherein the media streams are obtained after the encryption processing. Therefore, the fact that the recoding server can record third media streams of the first terminal and fourth streams of the second terminal is achieved.

Description

technical field

[0001] The invention relates to media stream processing technology, in particular to a method for recording encrypted media streams and switching control equipment. Background technique

[0002] In an Internet Protocol (Internet Protocol, IP for short) network, the recording server may record the media stream transmitted between the calling terminal and the called terminal by using IP packet capture and recording. For example: the network device through which the media stream transmitted between the calling terminal and the called terminal passes through mirrors the transmitted media stream, and the recording server captures the packets and records them as media files.

[0003] However, if the media stream transmitted between the calling terminal and the called terminal is encrypted, how to record the encrypted media stream is not given in the prior art. Contents of the invention
