Embodiment
To a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment only is used for explanation and explains the present invention, is not limited to the present invention below in conjunction with accompanying drawing.
Fig. 1 has shown the method flow diagram with AS realization sidebar that the embodiment of the invention provides; As shown in Figure 1; On NGN or IMS network, use AS and MS based on Session Initiation Protocol, and based on media session SGML (Media Sessions Markup Language; MSML) standard realizes sidebar, and step comprises:
Step 101: media server MS creates main meeting according to the request of joining from the main meeting of the establishment of application server AS and conference member, and the meeting member added becomes owner of meeting, becomes main conference member;
Step 102: when a said main conference member of initiating the member as son conference initiates to create and main meeting independently during the request of son conference to MS via AS; MS sets up son conference according to described request; And said son conference is initiated the member withdraw from from main meeting, join son conference;
Step 103:MS adds son conference with the notice as other son conferences member according to other the main conference members from AS, withdraws from said other main conference members from main meeting, joins son conference.
Said step 101 comprises: when main meeting initiate the member via AS when MS initiates to create the request of main meeting; MS creates main meeting according to described request; The member is initiated in said main meeting join main meeting, and initial audio attribute and/or the video attribute that the member is initiated in said main meeting is set; MS adds the notice of becoming owner of meeting according to other the main conference members from AS, joins main meeting to said other main conference members, and the initial audio attribute and/or the video attribute of said other main conference members are set.Furtherly, main meeting is initiated the member on the portal page, after this conference member that need have a meeting is specified, and page notice AS meeting.AS carries out session logic, and elder generation exhales the meeting member logical, calls out MS then, and after MS exhaled and leads to, AS was to the request of the main meeting of MS initiation establishment, and MS creates main meeting according to described request, and main meeting initiation member is joined main meeting.Then, the MS basis adds the notice of becoming owner of meeting from AS's with other main conference members, and other main conference members are joined in the main meeting.This moment, conference member was all in main meeting, and AS initially adds the initial audio attribute that audio attribute when becoming owner of meeting is designated as conference member with the meeting member, can listen when initially adding meeting like conference member talkative, then the initial audio attribute of conference member be can listen talkative; Can only listen when initially adding meeting like conference member not talkative, then the initial audio attribute of conference member be can only listen not talkative; Can only say when initially adding meeting and can not listen that then the initial audio attribute of conference member is can only say to listen like conference member; Not talkative can not listening when initially adding meeting like conference member, then the initial audio attribute of conference member is not talkative can not listening.If said main meeting is video conference, if the current video attribute of main meeting is for having idle screen, then conference member add become owner of meeting after, its video attribute is its video pictures of demonstration, and the idle screen number of main meeting subtracts one, promptly shows said conference member.
Also comprise the media description information exchange step before carrying out said step 101; Be specially: AS call-conference member and MS, and the medium type that comprises conference member, media coding type, the IP address of conference member and the media description information of port numbers that the meeting member is responded are sent to MS; AS is sent to conference member with the medium type that comprises MS, media coding type, the IP address of MS and the media description information of port numbers of MS response.That is to say that conference member and MS need be via AS exchange media description informations separately, so that MS provides main conferencing function and sidebar to the conference member of participating in main meeting.
In the said step 102, a said main conference member of initiating the member as son conference is created the operation of son conference, page notice AS on the portal page.AS carries out and creates the son conference service logic; After the inner application of AS is used to manage the son conference resource of son conference; Return the response of creating son conference to the page, page notice AS initiates the main conference member information of the needs adding son conference of member's selection about son conference then.Initiate the member to son conference, i.e. first son conference member, AS sends request to MS, and this conference member is withdrawed from, creates son conference, this conference member is added son conference from main meeting.
Said step 102 also comprises: MS is provided with audio attribute and/or video attribute that said son conference is initiated the member according to the request of said establishment son conference; AS and MS discharge said son conference and initiate audio resource and/or the video resource that the member takies in main meetings, and distribute the audio resource and/or the video resource of son conference for said son conference initiation member.That is to say that if AS judges that the audio attribute of son conference is quiet, then the AS audio attribute of initiating the member through the MS son conference is set to quietly, otherwise the audio attribute that son conference is initiated the member is set to it and initially adds the initial audio attribute when becoming owner of meeting.If AS judges the current video attribute of son conference for having idle screen, then AS shows said son conference initiation member through MS, otherwise, do not show said son conference initiation member.After completion was set, AS and MS discharged said son conference and initiate audio resource and/or the video resource that the member takies in main meetings, and distributed the audio resource and/or the video resource of son conference for said son conference initiation member.
Said step 103 also comprises: MS is provided with other son conferences member's audio attribute and/or video attribute according to the notice of said other main conference members adding son conferences; AS and MS discharge audio resource and/or the video resource that said other son conferences member takies in main meeting, and distribute the audio resource and/or the video resource of son conference for said other son conferences member.That is to say that if AS judges that the audio attribute of son conference is quiet, then the audio attribute of AS through MS son conference member is set to quietly, otherwise son conference member's audio attribute is set to its initial audio attribute.If AS judges the current video attribute of son conference for having idle screen, after then the son conference member added son conference, AS showed said son conference member through MS, otherwise, do not show said son conference member.After completion was set, AS and MS discharged audio resource and/or the video resource that said son conference member takies in main meeting, and distributed the audio resource and/or the video resource of son conference for said son conference member.
AS utilizes SIP information to send the notice that said other main conference members add son conference, and MS can only withdraw from a main conference member, and join son conference according to a SIP information from main meeting.Therefore, in son conference, add a plurality of conference members if desired, just need AS to send notice many times, only comprise a conference member information in each announcement information to MS.
Among the present invention, when conference member adds son conference, by AS control, make that the audio attribute of conference member is consistent with the audio attribute of son conference, the video attribute of conference member is by the current video attribute decision of son conference.For example, son conference is in mute state, and then conference member can not be made a speech after adding son conference, otherwise the audio attribute of conference member when adding son conference is the initial audio attribute of conference member; If idle screen display conference member is arranged in the son conference, video can show when then conference member added son conference, otherwise can not show.After conference member added son conference, audio resource and/or video resource that the last conference member of AS and MS takies in main meeting were released, and it is occupied that AS and MS go up audio resource and/or the video resource of conference member in son conference.Because conference member has withdrawed from main meeting, so son conference and main meeting are independent of each other, the conference member of son conference can't hear, can't see to the conference member in the main meeting, and the conference member of main meeting also can't hear, can't see to the conference member of son conference.
Said method comprises that also the son conference member returns the step of main meeting; Comprise: MS adds the announcement information of becoming owner of meeting according to the son conference member from AS; Withdraw from said son conference member from son conference; Join main meeting, become main conference member, and the audio attribute and/or the video attribute of said main conference member are set; AS and MS discharge audio resource and/or the video resource that said conference member takies in son conference, and distribute the audio resource and/or the video resource of main meeting for said conference member.Furtherly, the son conference member also can turn back to main meeting again.The son conference information about firms notice AS that returns main meeting that the page is selected the son conference member, AS sends notice to MS, this conference member is withdrawed from from son conference and adds become owner of meeting.If AS judges that the audio attribute of main meeting is quiet, then the audio attribute of AS through the main conference member of MS is set to quietly, otherwise the audio attribute of main conference member is set to its initial audio attribute.If AS judges the current video attribute of main meeting for having idle screen, then AS shows said main conference member through MS, otherwise, do not show said main conference member.That is to say that conference member returns main meeting and controlled by AS, make that the audio attribute of conference member is consistent with the attribute of main meeting, the video attribute of conference member is by the current video attribute decision of main meeting.For example, main meeting is in mute state, and then conference member can not be made a speech after returning main meeting, otherwise the audio attribute of conference member when returning main meeting is the initial audio attribute of conference member; If main meeting is video conference, then when being useful on display conference member's idle screen in the main meeting, conference member can show when returning main meeting, otherwise can not show.After conference member returned main meeting, audio resource and video resource that the last conference member of AS and MS takies in son conference were released, and it is occupied that AS and MS go up audio resource and the video resource of conference member in main meeting.Because conference member has withdrawed from son conference, so son conference and main meeting are independent of each other, the conference member of son conference can't hear, can't see to the conference member in the main meeting, and the conference member of main meeting also can't hear, can't see to the conference member of son conference.
In addition; Request or said other main conference members that AS utilizes session initiation protocol SIP information to send the main meeting of said establishment to MS add the notice of becoming owner of meeting or the request of said establishment son conference or notice or the son conference member that said other main conference members add son conferences and add the notice of becoming owner of meeting, comprise a conference member information in the SIP information.
What Fig. 2 had shown that the embodiment of the invention provides creates a kind of call flow diagram of main meeting with AS, and as shown in Figure 2: step comprises:
Step 201:AS sends to conference member and adds " INVITE " that becomes owner of meeting;
Step 202: conference member is to AS response " 100trying ", and expression is received this " INVITE " and handled;
Step 203: conference member sends ringing information " 180 " to AS;
Step 204:AS sends confirmation " Prack " to conference member, to respond said ringing information " 180 ";
Step 205: conference member receives said confirmation " Prack ", and sends " 200Prack " to AS;
Step 206: conference member sends " 200INVITE " that comprises its media description information SDP1 to AS, and off-hook is replied; Said media description information SDP1 comprises IP address and the port numbers etc. of medium type, media coding type, the conference member of conference member;
Step 207:AS sends the solicited message " INVITE " that comprises conference member media description information SDP1 to MS;
Step 208:MS is to AS response " 100trying ", and expression MS has received described request information " INVITE " and handled;
Step 209:MS sends to AS and comprises " 200INVITE " of its media description information SDP MS1 and reply; Said media description information SDP MS1 comprises IP address and the port numbers etc. of medium type, media coding type, the MS of MS;
Step 210:AS sends confirmation " ACK " to MS;
Step 211:AS sends the affirmation information " ACK " of the media description information SDP MS1 that comprises MS to conference member;
Step 212:AS sends " INFO " to MS, and main meeting and the affiliation of main conference member are created in request;
Step 213:MS representes main conference creation success to AS response " 200INFO ", and main conference member added becomes owner of meeting.
Above-mentioned steps 201 to step 213 is to set up the call flow of main meeting, and success has added a conference member in main meeting in this process.Because the once above-mentioned flow process of every execution can only add a conference member, therefore, if add a plurality of conference members, need repeat above-mentioned steps.It should be noted that when adding other conference members, only need the meeting member be added and become owner of meeting and get final product, and needn't set up main meeting again.Be in step 212 and the step 213, AS sends to MS and adds the notice INFO that becomes owner of meeting about main conference member, and MS adds main conference member and becomes owner of meeting, and adds the response message " 200INFO " of becoming owner of meeting to AS response expression conference member.
Main conference member adds when becoming owner of meeting, and AS preserves the audio attribute of conference member, and this audio attribute is designated as the initial audio attribute of this conference member.If video conference, then conference member adds when becoming owner of meeting, the picture resources number of this video conference of AS record; With frame numbers is that four video conference is an example, can only show four conference members simultaneously at most, if current available frame numbers is zero; Can not be shown when then the active conference member adds meeting; If current available frame numbers is not 0, can be shown when then the active conference member adds meeting, the video pictures number of resources of meeting simultaneously subtracts 1.
Fig. 3 has shown the flow chart with AS realization sidebar that the embodiment of the invention provides, and as shown in Figure 3, step comprises:
Step 301: when son conference is created in request on the portal page, the page will be created the son conference request and send to AS when son conference is initiated member's (conference member of first adding son conference);
The son conference resource that the inner application of step 302:AS is used to manage son conference, and after success application, return the response message of creating son conference to the page;
Step 303: son conference is initiated the member after selecting to add the main conference member of son conference on the page, and the page sends to AS with main conference member information;
Step 304: initiate the member for son conference, AS sends to MS and creates and the independently request of son conference " INFO " of main meeting, and MS withdraws from this conference member, create son conference, also this conference member joined the son conference from main meeting;
Step 305:MS returns response message " 200INFO " to AS, and the expression son conference is created successfully, and the conference member described in the step 304 is withdrawed from, joins the current son conference from main meeting;
Step 306: to other conference members; Because this moment, son conference was successfully created; AS sends other main conference members to MS and adds son conference with the notice " INFO " as other son conferences member, and MS withdraws from the meeting member from, add son conference from main meeting according to said " INFO ";
Step 307:MS returns response message " 200INFO " to AS, representes that this conference member successfully withdraws from, adds son conference from main meeting.
In the above-mentioned steps 303; When conference member adds son conference; AS judges the audio attribute of son conference; If this moment, son conference was in mute state, the conference member authority of speaking initially added the audio attribute when becoming owner of meeting otherwise the audio attribute of conference member is a conference member when then conference member added son conference.If son conference is video conference, then the initial picture number of resources of son conference and main meeting is consistent, is four like the picture resources number of main meeting, and then the picture resources number of son conference also is four.When conference member adds the video son conference; If the video resource number of son conference is not 0; To be shown when then conference member adds son conference; The video pictures number of resources of son conference subtracts 1, and conference member is released in the video pictures resource that main meeting takies simultaneously, and the video pictures number of resources of main meeting adds 1; If when conference member added the video son conference, the video resource number of son conference was 0, will not be shown when then conference member adds son conference, conference member is released in the video pictures resource that main meeting takies.
In the above-mentioned steps 305; Because conference member has withdrawed from main meeting; So son conference and main meeting are independent of each other, the conference member of son conference can't hear, can't see to the conference member in the main meeting, and the conference member of main meeting also can't hear, can't see to the conference member of son conference.
In the above-mentioned steps 306; AS sends other main conference members to MS and adds son conferences with " INFO " as other son conferences member, and " INFO " information can only make a conference member withdraw from main meeting and adds son conference; Therefore; In son conference, add a plurality of conference members if desired, MS needs according to " INFO " that comprise conference member information from AS, and the meeting member is withdrawed from and adds son conference from main meeting successively.Other conference members are when main meeting is withdrawed from and add son conference, and AS is identical with above-mentioned steps 303 to the control of conference member audio attribute and video attribute.
Can find out from top step, in realizing the process of sidebar, audio attribute and video attribute when constructive process and the conference member that AS controls son conference fully switches in main meeting and son conference, and main meeting and son conference are independent of each other.
When the conference member of son conference need return main meeting; AS withdraws from and adds " INFO " that become owner of meeting from son conference to MS transmission son conference member and gets final product; After this, MS returns response message " 200INFO " to AS, representes that this conference member successfully withdraws from, adds and become owner of meeting from son conference.
Fig. 4 has shown the system architecture sketch map with AS realization sidebar that the embodiment of the invention provides, and as shown in Figure 4, system comprises application server AS and media server MS, wherein:
Said AS is used for sending to media server MS the request of main meeting of establishment and conference member affiliation, and independently request and other main conference members of son conference add son conferences with the notice as other son conferences member with main meeting to send establishment to MS;
