Embodiment

The embodiment of the invention provides a kind of method that realizes son conference, no matter is can set up son conference according to this method according to the main meeting that separates the context pattern realization or according to the main meeting that non-separation context pattern realizes.

The embodiment of the invention realizes that the son conference participant can be main conferenced party in the son conference method, also can be the irrelevant participant of main meeting.The medium type of main meeting and son conference can be different.Medium between main meeting and son conference can be generated strategy according to demand alternately; For example: son conference does not influence other participants of main meeting; Main meeting does not receive the Media Stream of son conference; The Media Stream that the irrelevant son conference participant of main meeting receives only son conference can not receive the medium of main meeting, comes the son conference participant of autonomous meeting then can receive the Media Stream of main meeting and the Media Stream of son conference etc. simultaneously.

Medium between main meeting and son conference alternately can be through the connection end point between context be set media stream pattern or/and the Media Stream output relation between associated end points be set in the son conference context realize.The media stream pattern of the connection end point between context is set; According to different situations can be the media stream pattern that is provided with between main conference context and son conference context connection end point; Or, the media stream pattern between participant context and main conference context connection end point is set perhaps through the media stream pattern between participant context and son conference context connection end point is set.Saidly be provided with that the Media Stream output relation between associated end points can be in the son conference context: the Media Stream topology that associated end points in the son conference context is set; If when the Media Stream of associated end points is described difficult the expression through topology in the son conference context, also can be the Media Stream mixed strategy that associated end points in the son conference context is set.Need to prove that said setting can be direct setting, also can be to make amendment here.

When participant leaves son conference, whether be that the participant of main meeting carries out different processing according to participant.For the irrelevant participant of main meeting, directly from son conference, delete this participant.After leaving son conference for the participant that comes autonomous meeting, need let it turn back to main meeting, therefore need connection and reduction participant the connection in main meeting of deletion participant in son conference.The connection of reduction participant in main meeting is the inverse operation of revising the connection of participant in main meeting when setting up son conference.For example when separating context pattern; The participant context was provided with the son conference connection end point originally; Then delete this son conference connection end point during reduction; If participant inserted end points and was arranged in the son conference context this moment, participant is inserted end points moves on in the participant context, with in the son conference context to main meeting connection end point deletion that should participant; Because participant leaves son conference; So the participant that need reset each participant in the son conference context during reduction inserts the audio mixing strategy of end points or participant connection end point; For example as far as one of them participant; The Media Stream that receive this moment just is the mixing output of the participant access end points or the participant connection end point of main meeting connection end point and other participants, does not comprise the output of the participant that has left son conference.If during non-separation context pattern; Can delete the participant of participant in the son conference context during reduction and insert end points; Revert to participant and insert end points in the main conference context end points being acted on behalf of in main meeting that should participant, with in the son conference context to main meeting connection end point deletion that should participant; Because participant leaves son conference; So the participant that need reset each participant in the son conference context during reduction inserts the audio mixing strategy of end points; For example as far as one of them participant; The Media Stream that receive this moment just is the mixing output of the participant access end points of main meeting connection end point and other participants, does not comprise the output of the participant that has left son conference.

The realization son conference method of the embodiment of the invention provides three kinds of basic models but is not limited to this, please consults Fig. 4 respectively to Fig. 6.At Fig. 4 to the Reference numeral among Fig. 6 be: C1 representes main conference context; C2 representes the participant context, and C3 representes the son conference context, and T1 representes that main meeting acts on behalf of end points; T2 representes that participant inserts end points; T3 representes main meeting connection end point, and T4 representes the son conference connection end point, and T5 representes the participant connection end point.

Fig. 4 realizes the basic model one of son conference for the embodiment of the invention.Among Fig. 4, comprise main conference context, participant context and the new son conference context of creating.Be provided with a main meeting connection end point in the son conference context; Be provided with a son conference connection end point in the participant context; Main meeting connection end point in the son conference context is connected with the son conference connection end point in the participant context, and participant inserts end points and is arranged in the son conference context.Main meeting connection end point in the participant context is acted on behalf of end points with the main meeting in the main conference context and is connected.

Group conferenced party is when coming the participant of autonomous meeting; The carrying associative operation that conference system is set up son conference comprises: if current participant be first participant in the son conference then set up the son conference context, in the son conference context, set up main meeting connection end point for participant.A son conference connection end point is set in the participant context; Said participant context is for existing or newly-built; This son conference connection end point can be to utilize end points idle in the participant context; Also can be newly-established, then the son conference connection end point in the participant context is connected with main meeting connection end point in the son conference context.Participant is set in the son conference context inserts end points.Participant inserts end points can be newly-built in the son conference context, perhaps the participant in the participant context inserted end points and move in the son conference context.The main meeting connection end point that is provided with in the participant context is acted on behalf of end points with the main meeting of main conference context and is connected.

In this basic model one, the medium between main meeting and son conference are the media stream pattern between participant context and son conference context connection end point to be set or/and the Media Stream output relation between associated end points in the son conference context is set according to the medium interactive strategy alternately; Perhaps, the media stream pattern between participant context and main conference context connection end point is set or/and the Media Stream output relation between associated end points in the son conference context is set according to the medium interactive strategy.Irrelevant participant can not receive main IMS conference medium if the medium interactive strategy is customized to main meeting; Then the Media Stream output relation between associated end points in the son conference context need be set to the irrelevant participant of this main meeting; The participant that the irrelevant participant of main meeting for example is set in the son conference context inserts the mixing output that participant that Media Stream that end points receives includes only other participants inserts end points, does not comprise the output of main meeting connection end point.Here said setting can be direct setting, also can be to make amendment.

Fig. 5 realizes the basic model two of son conference for the embodiment of the invention.Among Fig. 5, comprise main conference context, participant context and the new son conference context of creating.Be provided with a main meeting connection end point and participant connection end point in the son conference context, with the main meeting connection end point in the son conference context directly with main conference context in main meeting act on behalf of end points and be connected.Be provided with a son conference connection end point in the participant context; This son conference connection end point can be for newly-built upright; Also can be main meeting connection end point that the participant context is original as the son conference connection end point, this son conference connection end point is connected with participant connection end point in the son conference context.Participant inserts end points and is arranged in the participant context.

Group conferenced party is when coming the participant of autonomous meeting; The carrying associative operation that conference system is set up son conference comprises: if current participant is first participant in the son conference then sets up the son conference context; In the son conference context, set up main meeting connection end point and participant connection end point for participant; With the main meeting connection end point in the son conference context directly with main conference context in main meeting act on behalf of end points and be connected, and the contextual main meeting connection end point of participant is connected with participant connection end point in the son conference context as the son conference connection end point.Participant inserts end points and is arranged in the participant context.Need to prove; There has been the participant context originally; And original main meeting connection end point and the main meeting in the main conference context are acted on behalf of under the situation that end points has been connected in the participant context, need be the disconnection that is connected that end points is acted on behalf of in present son conference connection end point and the main meeting in the main conference context with main meeting connection end point original in the participant context.When creating the participant context, then need the main meeting connection end point in the participant context not acted on behalf of end points with the main meeting in the main conference context and be connected if there was not the participant context originally.

In this basic model two, the medium between main meeting and son conference are the media stream pattern between main conference context and son conference context connection end point to be set or/and the Media Stream output relation between associated end points in the son conference context is set according to the medium interactive strategy alternately.Irrelevant participant can not receive main IMS conference medium if the medium interactive strategy is customized to main meeting; Then the Media Stream output relation between associated end points in the son conference context need be set to the irrelevant participant of this main meeting; The participant that the irrelevant participant of main meeting for example is set in the son conference context inserts the mixing output that Media Stream that end points receives includes only the participant connection end point of other participants, does not comprise the output of main meeting connection end point.Here said setting can be direct setting, also can be to make amendment.

Need to prove; Be to be the basis in the above-mentioned basic model one to two with the main meeting model that separates context pattern; If main meeting model is the main meeting model of non-separation context pattern; Then can be converted into the main meeting model that separates context pattern earlier, promptly need set up an independent participant context, and set up relevant connection for participant; Specifically can realize through two kinds of schemes: a kind of scheme is that newly-built participant inserts end points and main meeting connection end point in the participant context; And insert end points to the former participant in the main conference context and act on behalf of end points as participant in the main meeting of main conference context, then end points is acted on behalf of in the main meeting of contextual main meeting connection end point of participant and main conference context and linked to each other, and participant terminal and participant access end points are linked to each other.Another kind of scheme is the former participant access end points in the main conference context to be moved on to continue to serve as participant access end points in the participant context; In main conference context, set up main meeting and act on behalf of end points for participant; In the participant context, set up main meeting connection end point, then end points is acted on behalf of in the main meeting of contextual main meeting connection end point of participant and main conference context and linked to each other.Need to prove,, when transform separating the main meeting model of context pattern, can end points not be acted on behalf of in the main meeting of contextual main meeting connection end point of participant and main conference context and linked to each other if for basic model two.

Fig. 6 is that the embodiment of the invention realizes the basic model three of son conference, and this model is that the main meeting model with non-separation context pattern is the basis.Among Fig. 6, comprise main conference context and the new son conference context of creating.Be provided with a main meeting connection end point in the son conference context; Be provided with a main meeting in the main conference context and act on behalf of end points; With the main meeting connection end point in the son conference context directly with main conference context in main meeting act on behalf of end points and be connected, participant access end points is arranged in the son conference context.Need to prove that this model also can be to be the basis with the main meeting model that separates context pattern.

For the situation that is the basis with non-separation context pattern; When group conferenced party is main conferenced party; The carrying associative operation that conference system is set up son conference comprises: if current participant is first participant in the son conference then sets up the son conference context; In the son conference context, set up main meeting connection end point for participant, with the main meeting connection end point in the son conference context directly with main conference context in the main meeting that is provided with act on behalf of end points and be connected.Main meeting connection end point in the son conference context is in the son conference context, newly to set up.End points is acted on behalf of in main meeting for main conference context setting, can with the participant of the original participant in main conference context insert end points as participant the main meeting in main conference context act on behalf of end points, also can newly-built main meeting act on behalf of end points.Participant is set in the son conference context inserts end points.Participant inserts end points can be newly-built in the son conference context.

For the situation that is the basis with the separation context pattern; When group conferenced party is main conferenced party; The carrying associative operation that conference system is set up son conference comprises: if current participant is first participant in the son conference then sets up the son conference context; For participant is provided with main meeting connection end point, main meeting connection end point can be newly-built in the son conference context in the son conference context, perhaps the main meeting connection end point in the participant context moved on in the son conference context.Participant is set in the son conference context inserts end points, participant inserts end points can be newly-built in the son conference context, perhaps the participant in the participant context inserted end points and move in the son conference context.The main meeting connection end point that is provided with in the son conference context is acted on behalf of end points with the main meeting in the main conference context to link to each other.If also have end points in the participant context, then delete associated end points and delete the participant context.

In this basic model three, the medium between main meeting and son conference are the media stream pattern between main conference context and son conference context connection end point to be set or/and the Media Stream output relation between associated end points in the son conference context is set according to the medium interactive strategy alternately.Irrelevant participant can not receive main IMS conference medium if the medium interactive strategy is customized to main meeting; Then the Media Stream output relation between associated end points in the son conference context need be set to the irrelevant participant of this main meeting; The participant that the irrelevant participant of main meeting for example is set in the son conference context inserts the mixing output that participant that Media Stream that end points receives includes only other participants inserts end points, does not comprise the output of main meeting connection end point.Here said setting can be direct setting, also can be to make amendment.

In the middle of above-mentioned three basic models; When group conferenced party is the irrelevant participant of main meeting; The carrying associative operation that conference system is set up son conference comprises: if current participant is first participant in the son conference then sets up the son conference context; Participant is set in the son conference context inserts end points, participant is inserted end points be connected with the participant terminal.It is that a newly-built participant inserts end points in the son conference context that participant access end points is set this moment.In addition; Also can create the participant context for participant; Participant is inserted end points to be arranged in the participant context; At the participant context son conference connection end point is set, the participant connection end point is set, the contextual son conference connection end point of participant is connected with the contextual participant connection end point of son conference at the son conference context.

So, no matter be to separate the context pattern or the main meeting model of non-separation context pattern, can realize son conference by top said three kinds of basic models.

Below introduce the concrete application example of the embodiment of the invention in detail.

Embodiment one, is that the participant of main meeting is set up the voice sub meeting, sees also Fig. 7 to Figure 10.Embodiment one corresponding above-mentioned basic model one.

Fig. 7 is that the son conference of the embodiment of the invention one is set up illustraton of model, and Fig. 8 is the illustraton of model after the embodiment of the invention one participant leaves son conference.Suppose that the illustraton of model before son conference is set up is Fig. 3 of the prior art.

Suppose that in voice conferencing main meeting is to realize according to the model that separates context pattern.Participant inserts end points and is arranged in the son conference context, employing be the original participant in the participant context to be inserted end points move on to and continue to serve as the scheme that participant inserts end points in the son conference context.The medium interactive strategy is: son conference does not influence other participants of main meeting, and main meeting does not receive the Media Stream of son conference, comes the son conference participant of autonomous meeting can receive the Media Stream of main meeting and the Media Stream of son conference simultaneously.A, B, C are main conferenced party, and A initiates to set up the voice sub request for conference, and invite B and C adding son conference, son conference to carry out after a period of time A and leave son conference and return main meeting, but do not delete son conference.

The context of Ca, Cb, the corresponding participant A of Cc difference, B, C among the figure, Cm is the son conference context, Cm ' is main conference context; TX is that the participant of each participant inserts end points, and TX0 is the son conference connection end point of each participant in the participant context, and TX1 is the main meeting connection end point in the son conference context of each participant; TX0 ' acts on behalf of end points for the main meeting of each participant in main conference context, and TX1 ' is the main meeting connection end point in the participant context of each participant.Topology in wherein main conference context (Cm ') and the son conference context (Cm) is each end points interconnection (bothway); Media Stream in the son conference context (Cm) between each end points flows to and can realize through the Media Stream topology of revising associated end points in the son conference context (Cm); Revise the Media Stream topology and adopt existing modification topologies; When if the Media Stream of associated end points is described difficult the expression through topology in the son conference context (Cm); Also can be to realize through the Media Stream mixed strategy of revising associated end points in the son conference context (Cm), the Media Stream mixed strategy that the embodiment of the invention is provided with each end points with the multimedia conferencing controlling packet through definition in H.248.19 be embodied as example but be not limited to this.

Fig. 9 is that the son conference of the embodiment of the invention one is set up flow chart, and Figure 10 is that the embodiment of the invention one participant leaves the son conference flow chart.

Fig. 9 comprises step:

Step a1-h1; MC receive that A initiates set up the request of son conference the time, participant A is moved on to the son conference from main meeting, need comprise at the carrying associative operation that MP accomplishes: set up the son conference context; Revise the medium of A in main meeting and connect, set up the connection of A in son conference.

Step a1-h1 may further comprise the steps; Wherein, step a1-b1, MC sends MOV.request message to MP; The son conference context is set up in requirement; And the original participant in main meeting of participant A is inserted end points (TA) move on in the son conference context, MP uses the MOV.reply message response, returns son conference context (Cm) and participant access end points (TA) move operation result that it distributes.

Wherein, Step c1-d1; MC sends ADD.request message to MP, require in participant context (Ca), to set up the son conference connection end point of participant A, and the stream mode of this end points is set to only send (" SendOnly "); MP uses the ADD.reply message response, returns the son conference connection end point sign (TA0) of the A of its distribution.

Wherein, Step e1-f1, MC sends ADD.request message, the address information parameter of carrying the son conference connection end point (TA0) in the participant context (Ca) to MP; The main meeting connection end point of A is set up in requirement in son conference context (Cm); And the stream mode of this end points is set to only receive (" RecvOnly "), MP uses the ADD.reply message response, returns the main meeting connection end point sign (TA1) of the participant A of its distribution.

Wherein, Step g 1-h1; MC sends MOD.request message to MP, and the address information parameter of carrying the main meeting connection end point (TA1) in the son conference context (Cm) requires son conference connection end point (TA0) to link to each other with main meeting connection end point (TA1); MP uses the MOD.reply message response, returns the negotiation execution result; So far, accomplish modification that participant connects and the establishment of connection in son conference in main meeting.

Step a2-l2, A invite B to add son conference, need to revise the medium of B in main meeting and connect, and set up the connection of B in son conference, and the audio mixing strategy of the associated end points of A, B is set.

Step a2-l2 may further comprise the steps; Wherein, step a2-h2 is because the son conference context is set up; Therefore at step a2 the participant of B is inserted end points (TB) when moving to son conference, only need directly in the son conference context, to move into the participant access end points (TB) of B.In addition other steps are identical with a1-h1.Like this, the connection of participant B in main meeting revised, and the connection in son conference is set up.

Wherein, Step I 2-j2; MC sends MOD.request message to MP; The participant that requirement is provided with participant A inserts the mixing output that end points (TA) can only be received the participant access end points (TB) of main meeting connection end point (TA1) and participant B, and MP uses the MOD.reply message response, returns execution result.

Wherein, Step k2-l2; MC sends MOD.request message to MP; The participant that requirement is provided with participant B inserts the mixing output that end points (TB) can only be received the participant access end points (TA) of main meeting connection end point (TB1) and participant A, and MP uses the MOD.reply message response, returns execution result.So far, participant B adds son conference, and the medium mixed strategy of each participant is accomplished setting according to the strategy of formulating.

Step a3-n3, C is invited the adding son conference, needs to revise the medium of C in main meeting and connects, and set up the connection of C in son conference, and A is set, B, the participant of C inserts the audio mixing strategy of end points.

Step a3-n3 may further comprise the steps, wherein, step a3-h3, a2-h2 is identical with step.
