Abstract
The present invention relates to a kind of master-slave mode TeleConference Bridge based on converged communication, comprise a videoconference management system, main Conference server with at least one with described main Conference server with relay connection mode communicate from Conference server, and described main Conference server and be describedly eachly all connected with a sip server separately in relay connection mode from Conference server, and described each sip server correspondence is connected with at least one participant's client, and described main Conference server and be describedly eachly arranged in different meeting-place from Conference server.The present invention adopts master-slave mode videoconference to design, very big raising personnel participating in the meeting quantity, thus making TeleConference Bridge can be not only mini-session service, also can be large-scale, decentralized conference service, and reduces main meeting-place access bandwidth requirement by the strange land setting of Conference server.
Description
Technical field
The present invention relates to converged communication technical field, particularly relate to a kind of master-slave mode TeleConference Bridge based on converged communication.
Background technology
Converged communication is also Unified Communication, be a kind of new traffic pattern utilizing computer technology and conventional communication techniques to merge one, it provides the multiple means of communication comprising phone, fax, file transfer, videoconference, video, cooperation, instant message, mail, note etc.Converged communication is no longer confined to telephone set, but expands to the equipment such as PC, PDA, phone, smart mobile phone, H323/SIP terminal.But converged communication can't provide the service quality (QoS) that can promise to undertake to ensure to black phone at present like that, because converged communication is based on IP switching technology, Media Stream transmits in the mode of packet, can not ensure that packet arrives on time, according to the order of sequence, according to quantity, voice communication is embodied in lose words, delayed speech, language tremble etc. has a strong impact on speech quality.Because the opening of IP network also brings safety problem, the problems such as virus is propagated, the attack of network certainly will affect the availability of network.
Centralized conference for traditional: single Conference server finite capacity, and if all focus on same Conference server, network bandwidth requirement is also very considerable, and reliability is also bad.Traditional centralized conference limitation has spatially been broken in converged communication videoconference, no matter in office, travel outside, be in and have a rest or even external, as long as use converged communication client, mobile phone, fixed line or special conference terminal just can to hold or participate in a conference.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of based on converged communication master-slave mode TeleConference Bridge, spatially there is circumscribed problem for solving centralized conference.
