Abstract
The invention provides a distributing type meeting method based on an SIP protocol, which comprises the following steps: meeting IDs of various meetings are preset, and the connection between a meeting originator and meeting participants of various meetings is established according to the meeting ID; during the process of the meeting, the meeting originator sends a first meeting notification to the meeting participants according to the meeting ID; and the meeting participants acquire the attribute information of other meeting participants of the meeting according to the first meeting notification. According to the technical scheme provided by the invention, the probability of the false operation of the user is decreased; meanwhile, the attribute information of other meeting participants of the same meeting is sent to the meeting participants by the meeting originator in the manner of the first meeting notification according to the meeting ID, so that each meeting participant can get the attribute information of other meeting participants in the meeting, the interactive quality of the meeting information is improved, and the user can get a better meeting effect; therefore, the distributing type meeting method based on an SIP protocol is particularly suitable for simultaneously holding various meetings under the distributing type meeting structure.
Description
Technical field
The present invention relates to based on Session Initiation Protocol Web conference technology, particularly relate to a kind of distributed conference method based on Session Initiation Protocol.
Background technology
Along with the development of the communication technology and the propelling of common carrier broadband access, and the fast development of 3G and NGN, conference system the general change towards the mode of network gradually.The specific implementation of Web conference, current H323 and the SIP of mainly containing because SIP is based on the agreement of text, has better extensibility, has very large development prospect in conference system.
Meeting based on Session Initiation Protocol is realized mainly comprises the distributed meeting of AD Hoc Conference() and centralized conferencing(XCON, centralized conference).Their main distinction is that holding of AD Hoc Conference is more flexible, need not the such Conference server that must configure a center of image set Chinese style meeting and just can carry out meeting, AD Hoc Conference only needs common SIP UA, just can hold a meeting, can carry out anywhere or anytime MPTY, not be subjected to the restriction of server.
Yet for AD Hoc Conference, because it is the Multi-Party Conference of being realized by SIP UA, the Conference server that whole conference process does not have to concentrate manages, there is not the Signalling exchange about meeting, in Multi-Party Conference, be the meeting promoter by one of them SIP UA() realized the function of data mixing, signaling is then fully identical with point-to-point meeting, the meeting promoter who only has responsible data mixing is just definite to know that it is presiding over a Multi-Party Conference, other SIP UA(is the meeting participant) can't know self whether to be in the Multi-Party Conference, more can't know other participant member's information about firms.
In sum, as the meeting participant among the AD Hoc Conference, can't obtain conferencing information, other participant information about firms etc., and when a SIP UA holds a plurality of AD Hoc Conference Multi-Party Conference at one time, the meeting promoter can't distinguish clearly to each meeting, easily make mistakes, effect of meeting is relatively poor.
Summary of the invention
Based on this, be necessary can't obtain conferencing information and other participant information about firms for above-mentioned meeting participant, the problem that the meeting promoter easily makes mistakes, effect of meeting is relatively poor provides a kind of distributed conference method based on Session Initiation Protocol.
A kind of distributed conference method based on Session Initiation Protocol comprises the steps:
The Conference ID of default each meeting is set up being connected between the meeting participant of meeting promoter and each meeting according to described Conference ID;
Carry out in the process in meeting, the meeting promoter sends the first notice of meeting according to described Conference ID to the meeting participant, wherein, comprise in described the first notice of meeting with the same meeting of target meeting participant in other meeting participant's attribute information;
The meeting participant obtains the attribute information of other meeting participant in the meeting of place according to described the first notice of meeting.
Above-mentioned distributed conference method based on Session Initiation Protocol, by in Session Initiation Protocol, having expanded Conference ID, when holding a plurality of distributed meeting, the meeting promoter utilizes Conference ID, in the situation that there is not the centralized conference server, can be easily each conferencing information and meeting participant's attribute information be carried out visual demonstration, reduced the probability of user misoperation; Simultaneously, the meeting promoter is according to Conference ID, mode with the first notice of meeting sends the attribute information of other meeting participant in the same meeting to the meeting participant, so that each meeting participant can be known the attribute information of other meeting ginseng person in self place meeting, improved the mutual quality of conferencing information, the user can obtain better effect of meeting, is specially adapted to hold simultaneously under distributed meeting framework a plurality of different meetings.

Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to the distributed conference method based on Session Initiation Protocol of the present invention.
Fig. 1 shows the distributed conference method flow chart based on Session Initiation Protocol of an embodiment, mainly comprises the steps:
S100, the Conference ID (IDentity, identify label number) of default each meeting is set up being connected between the meeting participant of meeting promoter and each meeting according to described Conference ID;
S200 carries out in the process in meeting, and the meeting promoter sends the first notice of meeting according to described Conference ID to the meeting participant, wherein, comprise in described the first notice of meeting with the same meeting of target meeting participant in other meeting participant's attribute information;
