Embodiment Construction

[0024] In order to facilitate those skilled in the art to understand and implement the present invention, the embodiments of the present invention are now described with reference to the accompanying drawings.

[0025] figure 1 Shown is the SIP-based media encryption conference system model, the conference control center and the media mixing server constitute the conference server. The user terminal is connected to the conference control center through the SIP session, and the media data formed in the conference is transmitted between the terminal and the media mixing server in the form of SRTP encryption. Wherein, the media data formed in the meeting may be audio data or video data, which is not limited in this embodiment of the present invention.

[0026] figure 2 It is a schematic diagram of the processing process of SRTP encrypted media data in the conference server in the conference for media encryption. The SRTP encrypted media data is transmitted between the termina...

Abstract

The invention provides an access method of a media encryption conference. The method comprises the following steps that: the receiving terminal of a conference server accesses a request of the media encryption conference; according to the request, a media decryption channel is established by consulting with the terminal; the request carries at least one media encoding and decoding and SRTP (Secure Real-time Transport Protocol) encryption algorithm supported by the terminal; if a pre-existing media encryption channel exists, the parameter of the pre-existing media encryption channel is the same as the media encoding and decoding and SRTP encryption algorithm supported by the terminal, and the terminal is added into the pre-existing media encryption channel; and the parameter of the media encryption channel comprises the media encoding and decoding and SRTP encryption algorithm. The invention also provides another access method of the media encryption conference and a corresponding conference server at the same time. As the method is used, the consumption of system resources of the conference server can be furthest reduced, and the number of access terminals contained by the conference server is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for accessing a media encryption conference. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application layer signaling control protocol supporting multimedia sessions proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Force), used to create, modify and terminate one or more participants session of the reader. Utilizing the flexible, simple, easy-to-implement and hardware-independent characteristics of SIP, the conference function can be well realized in the existing network environment. [0003] The SIP-based conference system is mainly composed of a conference control center and a media mixing server. The conference control center and the media mixing server can be collectively referred to as a conference server. Among them, the conference control center is the core of th...
