Preferably, described conference applications server also is used for after described multimedia conferencing is created successfully, initiates to invite to other conference member terminals by Session Initiation Protocol message.
Below in conjunction with the drawings and specific embodiments technical solution of the present invention is described in further detail.
Fig. 2 is establishment multimedia conferencing signaling process figure of the present invention, and key step is described below:
Step 201 can send the establishment request for conference (CreateConfReq) of carrying session initial information to Conf AS by control terminal, and described establishment request for conference is the http signaling;
The initial information of described multimedia conferencing comprises one or more in the following information: conference type (audio or video), Session Topic, conference creation person, meeting time span, conference member number, conference member list, chairman's password, passwords of visitors, member's password etc.If what hold is video conference, then the initial information of multimedia conferencing can also comprise the split screen number of meeting.
Step 204-215, by the standard procedure of Session Initiation Protocol, by SIP and SDP signaling switched-media resource information, both sides' talking link is consulted successfully, sets up the media channel between binding terminal and the IMS core net between IMS core net and the binding terminal;
The signaling that relates in the above-mentioned steps comprises: 100Trying, 180Ringing, PRACK, 200PRACK, 200OK, ACK.Those message are the Session Initiation Protocol standard message, do not have Chinese term at present.Wherein 200PRACK or 200OK message can be used for carrying the media resource information of binding terminal, to realize the media resource information exchange between IMS core net and the binding terminal.
Setting up with media channel in the present embodiment successfully is that example describes, unsuccessful if media channel is set up in other embodiments, then conference creation failure.
IMS core net handle is that media channel is set up the information synchronization of success or not to Conf AS with the state of binding terminal call link negotiation.Conf AS sets up the result with media channel and creates the result as multimedia conferencing, upgrades the multimedia conferencing state for to create successfully.
Step 216, ConfAS gives the meeting control terminal conference creation result notification by HTTP message;
Step 217 can send subscription (Subscribe) message to Conf AS by control terminal, to subscribe to conferencing information;
Step 218, ConfAS subscribes to success response to meeting control terminal feedback;
Step 219-220, Conf AS is to meeting control terminal (notify) message of sending out public notice, be used for sending to the meeting control terminal conferencing information of its subscription, the conferencing information that the meeting control terminal of Conf AS feedback is subscribed to comprises one or more of following information: conference type, Session Topic, conference creation person, meeting time span, conference member number, meeting-place controlled attribute etc.
Above-mentioned meeting-place controlled attribute is exactly the controlled attribute in meeting-place, and whether can be used for sign has control to meeting, perhaps identifies to shared resource access control power, as whether public resources such as right to speak, video demonstration are had control.
Conferencing information than session initial information more comprehensively and real-time stronger, for example, when the time of meeting is extended, can this information be sent to the meeting control terminal of having subscribed to conferencing information by notify message.
So far, multimedia conferencing is created successfully.
Step 221, Conf AS invites other members to add the meeting-place by signaling Message, does not do the detailed description point of this patent here.
Fig. 3 can be controlled and medium signaling process figure for multimedia conferencing of the present invention, and in the present embodiment, ConfAS closes with the IMS core net and is located at, and key step is described below:
Step 301 can be initiated to control order to the ConfAS/IMS core net by the SIP signaling by control terminal;
Described meeting control order is the operational order to multimedia conferencing, includes but not limited to issue orders: add member, removing members, increase meeting time span, conference mute or cancel quiet.
Step 302, the ConfAS/IMS core net sends meeting control result to the meeting control terminal,
Between binding terminal and the IMS core net during multimedia conferencing, the keep-alive all the time of conversation media circulation road.
One of ordinary skill in the art will appreciate that all or part of step in the said method can instruct related hardware to finish by program, described program can be stored in the computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of the foregoing description also can use one or more integrated circuits to realize.Correspondingly, each the module/unit in the foregoing description can adopt the form of hardware to realize, also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
