Problems solved by technology

It can be seen that this method does not need to use the MCU server, so there is no problem of excessive load on the MCU server. However, compared with the MCU server, the performance of the terminal in terms of computing power, bandwidth, and stability is average. Poor, so the quality of service (QoS, Quality of Service) of the meeting cannot be effectively guaranteed

example 1

[0071] Assume that there are 10 terminals currently joining the conference, which are terminal A to terminal J respectively. Among them, the CPU utilization, audio and video input bandwidth, and audio and video output bandwidth of terminal A and terminal B are correspondingly greater than or equal to the total CPU utilization, Total audio and video input bandwidth and total audio and video output bandwidth, then terminal A and terminal B are determined as eligible terminals.

[0072] Afterwards, the sum of the delays of terminal A and the other 9 terminals and the sum of the delays of terminal B and the other 9 terminals are respectively calculated, and the terminal with the smaller calculation result is used as the main node.

example 2

[0074] Assume that there are 10 terminals currently joining the multimedia conference, which are terminal A to terminal J, and there are two groups, namely group 1 and group 2. First, the CPU utilization rate, audio and video input bandwidth of the 10 terminals and the audio and video output bandwidth are compared with the CPU utilization, audio and video input bandwidth, and audio and video output bandwidth of group 1, assuming that the CPU utilization, audio and video input bandwidth, and audio and video output bandwidth of terminal A and terminal B are correspondingly greater than or equal to group 1 CPU utilization, audio and video input bandwidth, and audio and video output bandwidth, then terminal A and terminal B are eligible terminals; after that, compare the CPU utilization, audio and video Compare the video input bandwidth and audio / video output bandwidth with the CPU utilization, audio / video input bandwidth, and audio / video output bandwidth of group 2 respectively.

Abstract

The invention discloses a multimedia conference realization method, which comprises the following steps that: A, after receiving audio and video data acquisition requests from terminals participating in a conference, a server judges whether the terminals participating in the conference comprise terminals which can serve as a master node or not, executes a step B if the terminals participating in the conference comprise the terminals which can serve as the master node, otherwise executes a step C; B, the server takes the terminal as the master node if one terminal can serve as the master node, and selects one of the terminals as the master node if more than two terminals can serve as the master node, and the selected terminal is used for audio and video data transmission between every two terminals participating in the conference; and C, the server is used for the audio and video data transmission between every two terminals participating in the conference. The invention also discloses a multimedia conference realization device. By the method and the device, not only the load of the server can be reduced, but also the quality of service of the conference can be ensured.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for realizing a multimedia conference. Background technique [0002] Multimedia conference is a kind of network virtual conference realized through network communication technology. Specifically, it refers to the real-time long-distance information interaction and sharing of multiple geographically dispersed terminals through various methods such as images and sounds. Work collaboratively. [0003] The traditional multimedia conferencing system is based on the client / server (C / S, Client / server) architecture, and the micro control unit (MCU, Micro Controller Unit) server is the core network element, which is used to complete audio mixing or switching, Functions such as video mixing or switching, data distribution, and conference control, and send various processed information streams to each terminal joining the conference. However, this method will cause an...
