With reference to Fig. 1, be the control transfer method flow chart under a kind of conference status of the embodiment of the invention.
This method can comprise:
User equipment (UE)-1 initiates to shift to UE-2 the control transfer request of control, and in request message, comprise the meeting descriptor, control transfer request that this control shifts indication and meeting descriptor will directly send to object UE-2 or the SCC AS-2 through serving for UE-2 is transmitted to UE-2 for the SCC AS-1 of UE-1 service will comprise, and receive this control transfer request by UE-2.This meeting descriptor can comprise any one in the role's descriptor in meeting profile information, the meeting, the mode that participates in a conference, the instruction of whether subscribing to conferencing information or the meeting participant's information at least.
After UE-2 receives above-mentioned message, can in the UI of mobile phone, be shown to the user, then can whether decision-making allows changing over to of control according to the meeting descriptor by the user of UE-2, can certainly in UE-2, be pre-stored with the rule of correspondence of meeting descriptor and control transfer instruction, the keyword of meeting and the rule of correspondence of control access or command for stopping are for example described, science and technology---insert, amusement---stop, after UE-2 receives the meeting descriptor, preset the rule of correspondence according to this, can know directly that acceptance still refuses this control transfer request.No matter adopt which kind of mode, UE-2 is if the refusal control changes over to then and can return refuse information to SCC AS-2, SCC AS-1, then can set up conference status if accept according to the meeting descriptor, for example if comprise the information of UE-1 in the meeting descriptor for chairman role, then UE-2 will set up conference status with chairman's identity and preside over the meeting according to this Role Information after accepting the control transfer, avoiding the interruption of meeting, and then can carry out meeting control.
UE-2 can send this to SCC AS-1 through SCCAS-2 and accept message.The order of step 102 and step 103 can be adjusted, and does not limit herein.
The embodiment of the invention is passed through subscriber equipment and is received the control transfer request that includes the meeting descriptor, guaranteed that the user can send instruction according to the meeting descriptor, making subscriber equipment can receive the higher control corresponding with the meeting descriptor of accuracy inserts or command for stopping, significantly reduced the execution of false command, and subscriber equipment can remove to set up conference status according to the meeting descriptor, guarantee normally carrying out of meeting, improved user experience.
With reference to Fig. 2, be the control transfer method flow chart under the another kind of conference status of the embodiment of the invention.
This method can comprise:
In this step, be that the SCC AS-1 of first subscriber equipment service receives the first control transfer request of being initiated by first subscriber equipment, can comprise the meeting descriptor in this request.This meeting descriptor can comprise any one in the role's descriptor in meeting profile information, the meeting, the mode that participates in a conference, the instruction of whether subscribing to conferencing information or the meeting participant's information at least.
UE-1 issues the content of the message of SCC AS-1 and the message that SCC AS-1 sends to UE-2 may be different, but all comprise the meeting descriptor.
This SCC AS-1 is before sending the second control transfer request message, can also earlier to whether allowing the transfer of control to judge, this deterministic process can be same as the prior art, can be just to control transfer destination ground, also promptly whether second subscriber equipment is judged for the trusted object, wherein, this second user equipment information can be included in the control transfer request; Also can increase criterion, for example can also judge further except above-mentioned judgement whether the control of this transfer is the control of conference type,, then stop if not if then allow to shift.Certainly, also can in SCC AS-1, judgment rule be set as required, carry out judgement.If SCCAS-1 allows control to shift, then will ask finally to be forwarded to second subscriber equipment via the SCC AS-2 that is the second subscriber equipment service, if two users' equipment belongs to a SCC AS, then can directly be forwarded to second subscriber equipment, if SCC AS-1 does not allow control to shift, then can return refuse information to first subscriber equipment.
SCC AS-1 directly or through SCC AS-2 after second subscriber equipment sends the second control transfer request, if UE-2 accepts control and changes over to, then can directly or through SCC AS-2 accept message, thereby finish the transfer process of control to the SCC-1 answer.
Present embodiment passes through SCC AS and receives the control transfer request that includes the meeting descriptor, and send the request comprise the meeting descriptor to second subscriber equipment, guaranteed that second subscriber equipment can receive the higher control corresponding with the meeting descriptor of accuracy and insert or command for stopping, significantly reduced the execution of false command, and subscriber equipment can remove to set up conference status according to the meeting descriptor, guarantee normally carrying out of meeting, improved user experience.
Control is transferred to UE-2 is that example describes to be in UE-1 in the conference state below, and control shifts back UE-1 and can still be among the collaborative session.
Embodiment one:
With reference to Fig. 3, in the present embodiment, the control transfer method under the conference status can comprise:
Step 301, UE-1 sends the first control transfer request to SCC AS-1, and this first control transfer request comprises the meeting descriptor.
In this step, UE-1 sends by refer (reference) message, comprise in this refer message to carry out the indication that control shifts, and the meeting descriptor.SCC AS-1 is the SCCAS for the UE-1 service.
Wherein, the indication information that control shifts can be accomplished in several ways, for example:
1, indicate by the message body of in refer message, carrying the xml form, as
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<control?transfer/>
2, by the request-disposition message header indicate as:
Request-Disposition＝Control_Transfer
3, unite by Contact head and refer-to head and indicate, as:
Contact=＜UE-1 address 〉; Iscontrollee
Refer-To:<sip:UE-2@home2.net>；isController
Or
Contact=＜UE-1 address 〉; Actor=" Controllee "
Refer-To:<sip:UE-2@home2.net>；actor＝″Controller″
Wherein, the Contact head is used to represent to shift the state of back UE-1, and the refer-to head is used to represent to shift the state of back UE-2.It is controllee that SCC AS can shift the back according to UE-1, and UE-2 is that controller judges the transfer of having carried out control.Here Contact=＜UE-1 address 〉; Iscontrollee or Contact=＜UE-1 address 〉; It is controllee UE that back UE-1 is shifted in actor=" Controllee " expression.
Refer-To:＜sip:UE-2@home2.net 〉; IsController or Refer-To:＜sip:UE-2@home2.net 〉; It is controller UE that back UE-2 is shifted in actor=" Controller " expression.
4, unite by 2 contact heads and indicate, as
Contact=＜UE-1 address 〉; Iscontrollee
Contact=＜UE-2 address 〉; Iscontroller
The Contact head is used to represent to shift the state of back UE-1 and UE-2, and SCC AS can know that UE-1 initiates the control transfer request according to this information.Here Contact=＜UE-1 address 〉; It is controllee UE that iscontrollee shifts back UE-1; Contact=＜UE-2 address 〉; It is controller UE that iscontroller represents to shift back UE-2.
In the present embodiment, the meeting descriptor that comprises in the refer message can comprise the meeting profile information, the role's descriptor in the meeting, the mode that participates in a conference, meeting participant's information, whether needs to subscribe to the indication of conferencing information and the indication information that UE-2 is in meeting.The indication information that UE-2 is in meeting is optionally, and SCC AS-1 can release that UE-2 is follow-up should to be in the meeting by preceding 2 information.
In this step, the transmission of meeting descriptor also can have multiple implementation, for example can strengthen by SIP+mode of XML comprises above-mentioned conference relevant information, or the mode of only passing through xml comprises the meeting descriptor.
1, the method for SIP enhancing+XML is as follows:
A. can need indicate whether UE-2 to subscribe to by actortag for the indication that whether needs to subscribe to conferencing information at the refer-to message header, as follows:
Refer-To:＜UE-2 address 〉; Actor=" Conference-Participant_with/without_Subscription "
Also can indicate by the actor tag of contact head, as follows:
Contact=＜UE-1 address 〉; Actor=" Conference-Participant _ with/without_Subscription "
Here actor=" Conference-Participant_with_Subscription " expression is in the meeting, and has subscribed to conferencing information;
Actor=" Conference-Participant_without_Subscription " expression is in the meeting, and does not subscribe to conferencing information.
B. for other meeting relevant information, can comprise following one or multinomial:
Meeting profile information: meeting address (conference URI), theme, brief introduction, media description, the language of use etc.;
Role's descriptor in the meeting: meeting promoter, meeting presiding, meeting participant;
The mode that participates in a conference: when add meeting, how to add meeting etc.;
Meeting participant's information: other participants' common identity IMPU (IP Multimedia PublicIdentity:IP multimedia public identifier), contact address etc.;
The purpose of meeting descriptor is to SCC AS-1 on the one hand, and SCC AS-2 and UE-2 provide enough information, makes SCC AS-1, and SCC AS-2 and UE-2 can improve the accuracy that control shifts; On the other hand, if do not need UE-2 to subscribe to conferencing information, then need provide conferencing information to UE-2 by UE-1.
The mode that can pass through xml comprises above-mentioned meeting relevant information, and example is as follows:
＜!--conferencing information description--〉
<conference-description>
＜display-text〉the meeting introduction＜/display-text 〉
＜subject〉Session Topic＜/subject 〉

2, the method for only indicating by the mode of using the XML form is as follows:
Pass through xml message body fully and carry the meeting descriptor, increase on the basis that xml describes in the above and describe the field that whether needs object UE-2 to subscribe to, xml message body is given an example:
<？xml?version＝″1.0″encoding＝″UTF-8″？>

Step 302, SCC AS-1 judges whether to allow UE-1 that control is transferred to UE-2.
This deterministic process can be same as the prior art, just whether UE-2 is judged for the trusted object, also can increase criterion, for example can also judge further except above-mentioned judgement whether the control of this transfer is the control of conference type, if then allow to shift, then stop if not.Certainly, also can in SCC AS-1, judgment rule be set as required, carry out judgement.If SCC AS-1 allows control to shift, then change step 303 over to, if do not allow to return the UE-1 refuse information.
Step 303, SCC AS-1 sends the second control transfer request that comprises the meeting descriptor to SCC AS-2.
Wherein, SCC AS-2 is the SCC AS for the UE-2 service.Certainly, belong to the situation of a SCC AS for UE-1 and UE-2, this SCC AS can directly send the second control transfer request that comprise the meeting descriptor to UE-2, and its process of transmitting can be similar to SCC AS-2 process of transmitting with SCC AS-1.
In the present embodiment, SCC AS-1 can pass through Invite/re-Invite (inviting/invite again) message and send control and shift indication and meeting descriptor.
Shift indication for control, can indicate by the message body of in invite message, carrying the xml form, as:
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<control?transfer/>
Or indicate by the request-disposition message header, as:
Request-Disposition＝Control_Transfer
Can be included in for the meeting descriptor in the SDP message body of invite message or in the XML message body, wherein, the meeting descriptor can with step 301 in identical, specific as follows:
1, be included in the SDP message body of invite message, i.e. method by SIP enhancing+XML:
A. can indicate as Request-Disposition=no_Sub_Conf/Sub_Conf by the request-disposition message header for the indication of whether subscribing to conferencing information
Or inform that by not comprising allow-event:conference UE does not subscribe to;
Also can need indicate whether UE-2 to subscribe to conferencing information by the expansion of sip message head;
B. the indication information that is in meeting for UE-2 can pass through to increase isfocus parameter indication UE-2 and is in the meeting in contact message: for example
Contact＝<conference?URI>；isfocus
C. can adopt identical with the method described among the abovementioned steps 301b for other meeting relevant information.
2, be included in the xml message body of invite message, can adopt identical with the method for description in the abovementioned steps 301 (2).
Step 304, SCC AS-2 judges whether to allow UE-1 that control is transferred to UE-2.
This deterministic process can be same as the prior art, just whether UE-1 is judged for the trusted object, also can increase criterion, for example can also judge further except above-mentioned judgement whether the control of this transfer is the control of conference type, if then allow to shift, then stop if not.Certainly, also can in SCC AS-2, judgment rule be set as required, carry out judgement.If SCC AS-2 allows control to shift, then change step 305 over to, if do not allow to return SCC AS-1 refuse information.
Step 305, UE-2 receives the second control transfer request that comprises the meeting descriptor.
UE-2 receives the invite message that SCC AS-2 transmits in this step, and then can know that the control in this invite message shifts the meeting descriptor of indicating and being included in SDP message body or the XML message body.
For example, can know that UE-2 is in the meeting according to the isfocus parameter.Pass through xml message body and can know meeting profile information and the UE-2 role (conference creation person or meeting participant) in meeting etc.
UE-2 can be shown to the user in the UI of mobile phone after knowing the meeting descriptor, then can whether decision-making allow changing over to of control according to the meeting descriptor by the user of UE-2, receive this control transfer instruction corresponding by UE-2 then with the meeting descriptor.Can certainly in UE-2, be pre-stored with the rule of correspondence of meeting descriptor and control transfer instruction, the keyword of meeting and the rule of correspondence of control access or command for stopping are for example described, science and technology---insert, amusement---stop, after UE-2 receives the meeting descriptor, preset the rule of correspondence according to this, receive corresponding control transfer instruction.
After UE-2 receives the control transfer instruction, carry out access or the termination that control shifts,,, then return refuse information if stop if insert then carry out subsequent step according to instruction.
Step 306, UE-2 returns the control transfer to SCC AS-2 and accepts message.
Step 307, SCC AS-2 returns the control transfer to SCC AS-1 and accepts message.
Step 308, SCC AS-1 sends re-invite message to conference centre.
SCC AS-1 upgrades conference centre (conference focus), the contact address and the common identity IMPU that inform the meeting participant of conference centre change, and/or inform that described first subscriber equipment of described conference centre withdraws from meeting, described second subscriber equipment adds meeting.Conference centre can know that the common identity of meeting participant UE-1 and contact address change according to session ID, meeting participant's information of new record more, and send notify message to other meeting participants that subscribed to conferencing information, the content of message is IMPU and the contact address that meeting participant's common identity changes to UE-2, and/or UE-2 adds meeting, UE-1 withdraws from meeting.
Follow-up, UE-2 can continue meeting is controlled according to conference URI, active conference information and other meeting participant's information.For example:
UE-2 can delete this meeting participant by sending refer message to conference URI, is specially the IMPU and the method=bye message that comprise the participant among the refer-to; Can send refer message to conference URI increases this meeting participant, is specially to comprise new IMPU and method=invite message among the refer-to; Can send refer message to conference URI and delete meeting, be specially and comprise conference URI and method=bye message among the refer-to.
In the meeting descriptor that receives for UE-2, if comprise the instruction of subscribing to conferencing information, then UE-2 can send the request of subscribing to conferencing information to conference centre and know the meeting relevant information.
In another embodiment, also can not comprise the indication of whether subscribing to conferencing information in the meeting descriptor for the UE-1 transmission, subscribe to if desired, can pass through an extra message indication UE-2 by UE-1 and subscribe to meeting message to conference centre, for example UE-1 can send this indication by refer message to UE-2 by SCC AS, and concrete can be:
Refer-To:<conference URI ；
method＝Subscribe？event＝conference?&?expired＝3600>
Can also be SCC AS when sending the control transfer request, not carry the indication information of whether subscribing to conferencing information.If UE-1 has subscribed to conferencing information, then SCC AS initiates the request of subscription conferencing information by an extra message indication UE-2, SCC AS can realize by sending refer message to UE-2, is specially by the refer-to message header of refer message and indicates, and is as follows:
Refer-To:<conference URI ；
method＝Subscribe？event＝conference?&?expired＝3600>
Then, after UE-2 receives this indication, initiate a very short subscribe request of subscription time to conference centre again and know the meeting relevant information.
Present embodiment has been accomplished in several ways UE-1 and has sent the control transfer request that comprises the meeting descriptor to UE-2, thereby can guarantee that UE-2 can receive the higher control corresponding with the meeting descriptor of accuracy and insert or command for stopping, significantly reduced the execution of false command, and UE-2 can remove to set up conference status according to the meeting descriptor, guarantee normally carrying out of meeting, improved user experience.
And pass through in the control transfer request message, to comprise the meeting descriptor, can guarantee control shift to insert finish after, the processing meeting associative operation that new controller UE can be correct guarantees carrying out smoothly of meeting.In addition, whether UE-2 needs to subscribe to conferencing information by indication, can reduce UE-2 and rejudge the operation of whether subscribing to conferencing information, has reduced unnecessary alternately, has improved user experience.
Embodiment two:
With reference to Fig. 4, in the present embodiment, the control transfer method under the meeting special topic can comprise:
Step 401, UE-1 sends the first control transfer request to SCC AS-1, comprises the meeting descriptor in this first control transfer request.
Step 402, SCC AS-1 judges whether to allow UE-1 that control is transferred to UE-2.
Corresponding steps among step 401～402 and the embodiment one is similar, repeats no more herein.
Step 403, SCC AS-1 sends the second control transfer request to SCC AS-2.
In the present embodiment, SCC AS-1 can pass through refer message and send indication and the meeting descriptor that control shifts.
Shift indication for control, can indicate by the message body of in refer message, carrying the xml form, as:
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<control?transfer/>
Or indicate by the request-disposition message header, as:
Request-Disposition＝Control_Transfer
For the meeting descriptor, can be included in the SDP message body of refer message or in the XML message body, similar by the method for SIP enhancing+XML or only by the method for xml message body with the description of appropriate section in the previous embodiment one, repeat no more herein.
Step 404, SCC AS-2 judges whether to allow UE-1 that control is transferred to UE-2.
This step is similar with abovementioned steps 304, repeats no more herein.
Step 405, UE-2 receives the second control transfer request that comprises the meeting descriptor.
UE-2 receives the refer message that SCC AS-2 transmits in this step, and then can know that the control in this refer message shifts the meeting descriptor of indicating and being included in SDP message body or the XML message body.
After UE-2 receives the control transfer instruction, carry out access or the termination that control shifts,,, then return refuse information if stop if insert then carry out subsequent step according to instruction.
Step 406, UE-2 returns the control transfer by invite message to SCC AS-2 and accepts message.
Step 407, SCC AS-2 returns the control transfer by invite message to SCC AS-1 and accepts message.
Step 408, SCC AS-1 sends re-invite message to conference centre.
SCC AS-1 upgrades conference centre, informs that the meeting participant's of conference centre contact address and common identity IMPU change.Conference centre can know that the common identity of meeting participant UE-1 and contact address change according to session ID, meeting participant's information of new record more, and send notify message to other meeting participants that subscribed to conferencing information, the content of message is IMPU and the contact address that meeting participant's common identity changes to UE-2, or UE-2 adds meeting, UE-1 withdraws from meeting.
Follow-up, UE-2 can continue meeting is controlled according to conference URI, active conference information and other meeting participant's information.This step is similar with abovementioned steps 308, repeats no more herein.
Present embodiment has been accomplished in several ways UE-1 and has sent the control transfer request that comprises the meeting descriptor to UE-2, thereby can guarantee that UE-2 can receive the higher control corresponding with the meeting descriptor of accuracy and insert or command for stopping, significantly reduced the execution of false command, and UE-2 can remove to set up conference status according to the meeting descriptor, guarantee normally carrying out of meeting, improved user experience.
