Description
Technical field
The present invention relates to multimedia conferencing field, more particularly to a kind of multimedia conferencing control method and system.
Background technology
Multimedia conference system is to refer to be mutually related the integrated of sound, light, electric equipment and software with meeting.In multimedia
Either given a report in meeting room, summarized, reported, products Presentation etc., with the figure of computer interactive operation, text, sound, shadow, exhibition of paintings
Show, given full play to the sensory perception of participant, substantially increase effect of meeting.Multimedia in office realm, also increasingly
Embody its advantage.The mode for holding multimedia conferencing mainly has：1. colloquy type, such meeting is achieved in that
It is online to invite conference member to add meeting in real time under based on multi-media Situation.This meeting is generally adapted the discussion of instantaneity
View, conference member can arbitrarily make a speech.Its chairman be can not by the real-time management and control conference flow of software, meeting adjourned into
Member dismisses, and next time re-invites when opening meeting, so causes the time of meeting to waste and meeting discipline is careless and sloppy and can not expire
Foot conferencing form complicated and changeable.2. meeting template, this kind of meeting be achieved in that meeting before conference member is constituted
Group, and prior notice needs the conference member of participation.Meeting starts preceding member and is ready to online, and chairman passes through meeting mould
Plate initiating conference.This kind of conferencing can reduce the time that member is invited before meeting starts, and simply conference member can be carried out
Operational control, and meeting template can reuse.When but convention or multichannel conferencing resource are merged, meeting template
Relevant action can not be performed according to predetermined conference flow, it is impossible to which accurate conducting a meeting and easily omits agenda at the time,
Lack real meetings scene.
It is therefore desirable to be improved.
The content of the invention
In order to solve the above-mentioned technical problem, it is an object of the invention to provide a kind of multimedia conferencing control method and system.
The technical solution adopted in the present invention is：
A kind of multimedia conferencing control method, the described method comprises the following steps：
S1, each resource access device sends log-on message to soft switching server in main meeting-place meeting control terminal and meeting room, and complete
Into registration；
S2, main meeting-place meeting control terminal sends meeting room essential information and to resource access device information to Conference server, creates
Meeting room；
S3, main meeting-place Conference server is by receiving the application meeting room resource information that applicant sends, and it is pre- to configure meeting
Case；
S4, main meeting-place meeting control terminal sends request and opens meeting message to Conference server, and the Conference server takes to media
Business device application media resource；Conference server control terminal incoming call meeting and will add media server；The Conference server
Each resource is added into media server, and sets up media channel；Meeting is opened successfully；
S5, main meeting-place meeting control terminal sends a message to the prediction scheme action message of Conference server query configuration；Conference server with
Media apparatus interaction sets up media channel and pushing video flow to meeting control terminal；
S6, main meeting-place meeting control terminal sends addition sub-venue message to main meeting-place Conference server, and main meeting-place Conference server will
Sub-venue adds main meeting-place media server, the sub-venue to set up media channel with main meeting-place media server；
S7, meeting control terminal sends spokesman seat message to Conference server, realizes that entity meeting room switches spokesman；
S8, meeting control terminal uploads audio-video document to vod server, and the audio-video document is added meeting-place by Conference server,
And push to display screen；
S9, meeting control terminal sends ending message to Conference server and terminates meeting.
Further, the step S1, it includes：
Resource access device sends registration message to soft switching server, without authentication；Soft switching server response concurrent
Send the order that needs are discerned to resource access device；The resource access device sends registration message to soft switching server, takes
Band authentication information；The soft switching server is authenticated.
Further, the step S2, it includes：Meeting control terminal receives order setting meeting room essential information and resource connects
Enter facility information, and send request and preserve to Conference server meeting room essential information and resource access device information.
Further, the step S3, it includes that the side of examination ＆ approval receives and consenting user application meeting room resource information, then
The application meeting room resource information to Conference server is sent, if the Conference server judges application period Lothrus apterus,
Return to the successful message of application and preserve this application information；Examination ＆ approval side notifies user's application result, and sends a message to indemnifying party,
Notify meeting support mission；Indemnifying party sends a message to Conference server configuration meeting prediction scheme；It is pre- that Conference server preserves meeting
Case simultaneously returns to response.
Further, the step S4, it includes：Can control terminal send request and open the message of meeting to conference service
Device, the Conference server sends the request of application media resource to media server；Conference server will control terminal and each
Resource access device incoming call meeting, and set up media channel with media server；The Conference server send open meeting into
The information of work(extremely can control terminal.
Further, the step S5, it includes：Can control terminal send a message to Conference server, query configuration it is pre-
Case action message, the Conference server returns to response；
Can control terminal send in conference session message to Conference server preview action；Conference server and media apparatus interaction
