Embodiment
The invention provides a kind of implementation method of multi-party communication, this method discloses a kind of multi-party communication technology that is easy to realize, its main design philosophy is: the calling subscriber is when a plurality of called subscribers send information, service server at first is recorded in the information that call subscriber terminal sent among the media resource entity, and service server is controlled this media resource entity again and distributed the information that it writes down to each called user terminal then.
Wherein, service server with the information that call subscriber terminal sent be recorded among the media resource entity method can for: at first set up the media session between call subscriber terminal and the media resource entity, this call subscriber terminal media session that can pass through to be set up is sent to the media resource entity with information then.In addition, the method that service server control media resource entity is sent to each called user terminal with information also can for: at first at each called user terminal, set up the media session between this called user terminal and the media resource entity, the media resource entity passes through the media session set up and sends information to this called user terminal then.
The service logic of multi-party communication of the present invention can be provided by existing application service server (AS) in the communication network, service server also can independently be set this service logic is provided.When the calling subscriber when a plurality of called subscribers send information, can dial the service access code that sets in advance, current calling can be routed to the described service server that is used to provide multiway telecommunication service logic of the present invention according to this service access code, this service server will access to the media resource entity to current calling, thereby call subscriber terminal can be recorded in the information of self current transmission among the media resource entity.Media resource entity of the present invention can be the newly-increased entity in the communication network, also can adopt the Media Resource Server (MRS in the broadband network, Media Resource Server) or the enhanced smart peripheral hardware (AIP) in the narrowband network, the present invention does not limit for the equipment of the concrete representative of media resource entity.The present invention states the calling subscriber mails to called subscriber's information and can be text message or pictorial information or voice messaging or image information or this combination in any.Described called subscriber can for: such as Public Switched Telephone Network, global system for mobile communications (GSM) etc. fixing/mobile phone user, or instant communication users such as QQ, MSN, or E-mail address (email) user; So the CSI called subscriber identification of input can be fixing/Mobile Directory Number or instant messaging number or email address accordingly when the calling subscriber made a call.
Fig. 1 is the inventive method one preferred embodiment handling process schematic diagram.The processing entities that present embodiment relates to comprises: call subscriber terminal, service server, MRS and called user terminal, it is identical that wherein called user terminal has the processing of a plurality of and each called user terminal, so Fig. 1 only illustrates a called user terminal for simplified illustration; In addition, the information that is sent in the present embodiment is voice messaging, promptly realizes multipartite voice communication, and the dialogue-based initiation protocol of present embodiment (SIP, Session InitiationProtocol), and the media session of being set up is the real-time transport protocol (rtp) session.As shown in Figure 1, concrete treatment step comprises:
Step 100: call subscriber terminal sends invites (INVITE) message to give service server, to carry default service access code and the Session Description Protocol of this call subscriber terminal (SDP, Session Description Protocol) information in this INVITE.This service server returns 100 again and attempts (Trying) message to call subscriber terminal, current calling is accessed to MRS with indication call subscriber terminal self.
Step 101: this service server is transmitted the above-mentioned INVITE that carries call subscriber terminal SDP information and is given MRS, and this MRS sends 100 Trying message to this service server.
Step 102: this MRS also sends 180 rings (Ringing) message and gives service server, indication on call link.
Step 103～step 104: this MRS returns as 200 OK message of the response message of the described INVITE of step 101 and gives service server, and this 200 OK message is carried the SDP information of MRS.The 200 OK forwards that this service server will receive are again given call subscriber terminal, and this 200OK message will be as the response message of the described INVITE of step 100.
Wherein, in the step 100, the INVITE that current call subscriber terminal sends can be routed to this service server according to described service access code.And on the other hand, can carry out SDP negotiation after MRS and call subscriber terminal the other side's who carries in receiving this INVITE the SDP information, thereby the concrete mode of determining the record current information is as the media transmission protocol that is adopted, voice encoding and decoding format or the like.Here, can carry out according to existing protocol about the detailed process of SDP negotiation, the present invention does not limit this, so this paper is not described further this yet.
Step 105: through the processing of above-mentioned steps 100 to step 104, set up the RTP session connection between call subscriber terminal and the MRS, call subscriber terminal is sent to MRS with the information that will send, and MRS carries out record to the information that receives.
In the present embodiment, the information that is sent is voice messaging, set up the RTP session between call subscriber terminal and the MRS, call subscriber terminal can directly send voice messaging to MRS, just as direct and other user's communication, MRS then can get off the voicemail logging that receives as recorder.
When call subscriber terminal has write down information in the media resource entity after, can further discharge the media session between call subscriber terminal and the media resource entity, this processing that discharges media session is as described in step 106 and the step 107.
Step 106～step 107: call subscriber terminal is prepared to disconnect session connection with MRS after MRS has successfully write down its voice messaging that will send, and then sends goodbye (BYE) message to MRS.MRS returns 200 OK message and gives service server, and this service server returns to call subscriber terminal with this 200 OK message again, thereby call subscriber terminal is connected with the MRS disconnection, finishes the RTP session.
Then, service server makes a call at each called user terminal of current calling, to set up the RTP session between media resource entity and each called user terminal.Carry out following steps 108 to step 122 at each called user terminal.
Step 108: service server sends INVITE to called user terminal, does not carry SDP information in this INVITE.
Step 109: this called user terminal returns 100 Trying message again and gives service server, self connects with the indicating services server.
Step 110: this called user terminal also sends 180 Ringing message to service server, the link of the current calling of indication on.
Step 111: called user terminal is answered, thereby called user terminal and service server are set up the RTP session connection.
When the called user terminal shutdown, in the time of maybe can't connecting, above step 108 to step 110 will be carried out with timing or alternate manner circulation, till called user terminal is answered.
Step 112: this called user terminal returns as 200 OK message of the response message of the described INVITE of step 108 and gives service server, and this 200 OK message is carried the SDP information of this called user terminal.
Step 113: this service server sends to MRS and carries the INVITE of called user terminal SDP information, prepares to set up the RTP session connection with MRS.
Step 114: this MRS returns 100 Trying message again and gives service server, self connects with the indicating services server.
Step 115: this MRS also sends 180 Ringing message to service server, the link of the current calling of indication on.
Step 116: this MRS returns as 200 OK message of the response message of the described INVITE of step 113 and gives service server, and this 200 OK message is carried the SDP information of this MRS.
Step 117～step 118: this service server sends the ACK message of the SDP information of carrying MRS again to called user terminal, this ACK message will be as the affirmation message of the described 200 OK message of step 112; Simultaneously, this service server also returns ACK message as the affirmation message of the described 200 OK message of step 116 to MRS.
Like this, service server is set up the RTP session with MRS and called user terminal respectively, and MRS and called user terminal have also obtained the other side's SDP information respectively, therefore can finish the SDP negotiation process, for the transmission of current speech information is got ready.
Step 119: service server is set up the RTP session with MRS and called user terminal respectively, on macroscopic view, in fact is exactly the RTP session of having set up MRS and called user terminal, and MRS can play the voice messaging that it write down before to called user terminal.
Here, service server can be after having set up session connection respectively with MRS and called user terminal respectively, the link address of called user terminal and the link address of MRS are notified to MRS and called user terminal respectively, make and set up direct RTP session connection between called user terminal and the MRS, like this, MRS can directly be passed to called user terminal with voice messaging.
Whenever MRS after a called user terminal has sent information, service server can further discharge the RTP session between this called user terminal and the MRS, this processing that discharges the RTP session as step 120 as described in the step 122.
Step 120: the RTP session between service server release self and the called user terminal, processing comprises: service server sends BYE message to called user terminal, and this called user terminal returns 200 OK message again.
Step 121～step 122: the RTP session between service server release self and the MRS, processing comprises: service server sends BYE message to MRS, and this MRS returns 200 OK message again.
Step 123: to the described processing at a called user terminal of step 122, the voice messaging that just can finish each called user terminal one by one sends by above-mentioned steps 108, thereby the information in the multi-party communication of the present invention that realizes sends purpose.
For making call subscriber terminal whether finish transmission by awareness information, also can further comprise step 124 after step 123: service server is configured to indication information and sends successful information and send to call subscriber terminal.Wherein, the information of being constructed can have various ways, such as: instant message (IM), short message or the like; And can adopt multiple existing mode to send this to be used for indication information and to send successful information, such as: adopt the mode of point-to-point short message (SMPP) to send by Short Message Service (SMS) transmission or employing instant messaging (IM) instrument.
In addition, after information that service server writes down in MRS sends to all called user terminals,, the information that has sent can be deleted from MRS, then can after step 123, further comprise for saving resource:
Step 125: service server sends the INVITE of indication deletion information, in this INVITE portability prepare the information of deletion sign, show indication field of deletion information or the like.This MRS sends 100 Trying message again to service server.
Step 126: simultaneously, this MRS also sends 180 Ringing message to service server.
Step 127～step 128:MRS returns 200 OK message and gives service server after connecting link, set by step the voice messaging that has sent of 125 described INVITE deletions self preservation; This service server returns the affirmation message of ACK message as this 200 OK message.
Here, for making whole communication process more user friendly, service server can also further send to call subscriber terminal after the information of deletion MRS self and be used to indicate the successful information of deleting.And in order to finish speech play, service server can at first be set up the RTP session between call subscriber terminal and the MRS, be used to indicate the successful information of deleting to the call subscriber terminal transmission after successfully deleting the information that is write down again by this MRS then, such as: the voice of playing " successfully deleting ".Above-mentioned steps 125 has been set up the RTP session between service server and the MRS to step 128, this service server also can be set up the RTP session with call subscriber terminal simultaneously, thereby sets up the RTP session between call subscriber terminal and the MRS.
In addition, before playing voice, call subscriber terminal also will obtain the SDP information of MRS, to finish SDP negotiation, for speech play is got ready.So, the SDP information that can further carry MRS in the described 200 OK message of step 127, service server can pass to call subscriber terminal with the SDP information of MRS then, and call subscriber terminal also can be set up signaling by session self SDP information is passed to MRS by service server.
MRS to call subscriber terminal issued be used to indicate the successful information of deletion after, service server also needs further to discharge the RTP session between MRS and the call subscriber terminal, as described in step 129.
Step 129: service server and MRS discharge the RTP session, and processing comprises: send BYE message to MRS, this MRS returns 200 OK message and gives this service server.This service server also discharges RTP session between self and the call subscriber terminal by same mode.
The present invention also can utilize other relevant supplementary service server to assist to realize multi-party communication of the present invention, can be further and the supplementary service server such as: described service server, presence server (Presence Server) links to each other, so that the presence service relevant with multi-party communication of the present invention to be provided, can utilize presence service to send the notice that is used to indicate information extraction to a plurality of called user terminals of having logined presence server, listen to the information that call subscriber terminal is kept at MRS to point out each called user terminal, this is used for indicating the notice of information extraction can carry the address of the information that MRS writes down, called user terminal is after obtaining this notice, can extract corresponding information to the MRS request by this message address, thereby MRS can send information to called user terminal.So-called presence service is in the particular communication mode, according to certain access criterion, obtain user's presence information in real time, such as: information such as User Status, communication capacity, individual's reference, and a kind of method of presence information being presented to other user of current participation communication.Here, for the called subscriber as fixing/mobile phone user, the calling subscriber can directly initiate a call to the called subscriber, is answered by the called subscriber; And,, then can use instant message (IM) to notify this called subscriber by the supplementary service server if it also is the supplementary service user simultaneously for for the called subscriber of instant communication user or email business.
As shown in Figure 1, service server can be when setting up the RTP session with the part called user terminal, at other simultaneously for called subscriber's execution in step 122 ' of Presence user: described service server is determined the listed presence server of called user terminal, send information (MESSAGE) message of carrying the IM content to presence server, this presence server is given IM down sending content in this MESSAGE message to have logined in each called user terminal of self and to this service server and is returned 200OK message as replying, each called user terminal is asked information extraction according to the IM content that receives to MRS again, and MRS sends information again to called user terminal.
Here, entrained IM content is exactly a kind of notice that is used to indicate information extraction, and it can comprise: keyword of the address of the information that extract, indication information extraction or the like.The address of described information can comprise: access code, can be for the chained address etc. of visit, called user terminal use described access code can directly connect MRS to come information extraction, but and click this can for chained address of visit just download message to local.The present invention is used to indicate the specific implementation of the notice of information extraction not limit for described.
In addition, above-mentioned supplementary service server is not limited only to presence server, also can adopt MSN, the courier of Yahoo instant messaging (IM) servers such as (Yahoo Messenger) or location server or the like.When adopting other supplementary service server, specific implementation is identical with the mode that combines with presence server noted earlier, and this paper describes in detail no longer one by one.
Here of particular note: if current each called subscriber is the supplementary service user, then service server can come transmission information by the media session of setting up MRS and each called user terminal, can come the advise called subscriber terminal to come information extraction by the supplementary service server at each called subscriber; If it is the supplementary service user that the part called user terminal is arranged in current each called user terminal, then service server can come transmission information by the media session of setting up MRS and called user terminal at the called subscriber of non-add service-user; Be supplementary service user's called subscriber at each simultaneously, come the advise called subscriber terminal to come information extraction by the supplementary service server.
Among the above-mentioned various embodiment, MRS is before called user terminal transmission information, can at first carry out the media capability that media capability negotiation obtains called user terminal with called user terminal, then when called user terminal sends information, information is carried out sending to called user terminal again after the media format conversion by the media capability of called user terminal.Wherein, MRS can carry out media capability negotiation when setting up media session with called user terminal, and MRS also can obtain the media capability of called user terminal by the supplementary service server; When the media capability of called user terminal is not supported the media formats of the information that present MRS writes down (such as: what MRS write down is voice messaging, and called user terminal is only supported text message), MRS just can by the media capability of its resulting called user terminal to information carry out media format conversion (such as: convert voice messaging to text message).
Multi-party communications method of the present invention can be implemented in various communication network frameworks, comprising: next generation network (NGN), 3G, Public Switched Telephone Network, IP Multimedia System (IMS) or the like, the present invention does not limit this.
