Description
Technical field
The present invention relates to the communications field, more specifically, relate to for example implementation method and the device of the middle blind transferring operation of next generation network (NGN).
Background technology
Calling switching (Call Transfer) is a kind of supplementary service in the communication system: when two users (user A and user B) set up conversation in communication system after, one of them user (is example with user B) can ask current talking is given to third party (user C), promptly between user A and user C, set up conversation, and the conversation speech channel between disconnect user A and the user B.A kind of common application scenarios of this business is: general manager's secretary (user B) answers all incoming calls (user A) earlier, asks the other side's one's purpose in coming clearly, for the phone that needs the general manager to answer in person, utilizes call switching business to be given to general manager (user C).
Call switching business has two types: a kind of is inquiry transferring, be that user B sets up conversation (whether inquiry user C agrees the conversation with user A) with user C earlier before switching, and then initiation transfer-request, make user A and user C set up conversation, simultaneously the conversation of two between disconnect user B and user A, user B and user C speech channel respectively.Another kind is blind commentaries on classics, and promptly user B does not set up conversation with user C earlier, but directly initiates transfer-request, makes user A and user C set up conversation.
Be that call switching business can be finished voluntarily by user's intelligent terminal in the next generation network (NGN) of core with IP Multimedia System (IMS), perhaps cooperating with application server (AS) in the network and finish by intelligent terminal.
Fig. 1 is that a kind of typical services in the next generation network realizes framework, wherein, application server (AS) (may exist a plurality of, be respectively applied for different business) link to each other with the service-call session control function (S-CSCF) of user attaching network by interface, service message between user terminal A and the user terminal B (with dashed lines sign) can be flowed through separately application server (according to the kind of customer service, may pass through different application servers), application server can be by the business of various processing to realize enriching to service message.User terminal A and user terminal B utilize the service message exchange and consult the media parameter that both sides supported, between is set up Media Stream and connected (using solid line), and Media Stream is used for transmitting data such as conversation voice packets.
Fig. 2 is calling switching (blind commentaries on classics) flow process in existing third generation partner plan (3GPP) technical specification.In this flow process, user terminal #1 (user A) and user terminal #2 (user B) have set up conversation (step 1) earlier; User terminal # 2 sends a transfer-request to user terminal #1 then, passes to user terminal #1 (step 2～8) through network equipment (Proxy-Call Session Control Function, service-call session control function etc.); User terminal #1 sends to user terminal #3 (user C) earlier and invites request after receiving transfer-request, sets up conversation and connect (step 9～21) between user terminal #1 and user terminal # 3; User terminal #1 sends switching affirmation response then, and the result notification that switching is successful is given user terminal #2 (step 22～26); The terminal # 2 of end user sends on-hook request, the conversation speech channel between disconnect user terminal # 2 and the user terminal #1 (step 27～36) to user terminal #1.
Fig. 3 is the blind turn of tidal stream journey in existing high-level network telecommunications internet fused business and agreement organizations (TISPAN) technical specification.For simplicity, the network equipments such as Proxy-Call Session Control Function, service-call session control function have been omitted among this figure.At this flow process section start, user terminal-A (user A) and user terminal-B (user B) are in the communication process, ((application server-B) all participates in this communication process to the application server of user terminal-A, for separately service object provides supplementary service for application server-A) and the application server of user terminal-B; By user terminal-B user terminal-A is changed to then and calls out hold mode (be that service message can intercommunication, but Media Stream temporarily interrupting); User terminal-B sends a transfer-request (step 1～3) to user terminal-A then, after user terminal-A represents to accept this request (step 4～6), user terminal-B sends the on-hook request to user terminal-A, disconnects conversation speech channel (step 7～12) between the two; User terminal-A sends to user terminal-C (user C) and invites request then, sets up conversation (step 19～30) between user terminal-A and user terminal-C; In said process, user terminal-A prepare to user terminal-C send invite request before and during speech channel at connecting subscribers participating terminal-C, all can utilize notification message that correlation circumstance is notified to user terminal-B (difference corresponding step 13～18, step 31～36).
More than a common feature of two flow processs be, the call forwarding request that user B initiates is given user A by network delivery, be responsible for being initiated to the conversation of third party user C by user A, and in this process, will call out the switching progress and circulate a notice of user B to the switching that makes a call by user A.There is following problem in this:
1) user terminal A must be supported the processing to call forwarding request, and request (comprise every relevant parameter correctly is set) is invited in the conversation that needs correctly to be initiated to third party user C, and needing can be correctly to user B report call switching progress.Calling out switching is the business of user B, to user terminal A to require too high be not too rational.
2) in existing procedure, user A invite the opportunity, user A of user C to opportunity of user B report call switching progress, all grasp voluntarily by user terminal fully the opportunity that user B discharges original conversation, this makes call switching business too rely on terminal.If the standard that each terminal is followed inconsistent (for example, user B on-hook opportunity is different in Fig. 2 flow process and Fig. 3 flow process), can cause in consolidated network user is inconsistent to the user experience of same business, influences the satisfaction of user to Virtual network operator.Even more serious is, if do not work good between each user terminal, can cause this service fail, and for example, user terminal A transfer successfully to user terminal B circular, and user terminal B does not just discharge original conversation.
In a word, the realization of call switching business too relies on user terminal in the prior art, has great limitation and hidden danger.Therefore, operator wishes to strengthen the control to call switching business.

1) user B uses user terminal-B to send call forwarding request to application server-B, and requirement will be called out switching and be given user C.
2) application server-B judges that the user has the authority of using call switching business, sends to user B and calls out the switching acceptance response, and the expression request is accepted.
3) application server-B sends the switching notification message to user B, and expression prepares to be initiated to the calling of user C.
4) user B returns to application server-B and confirms response.
5-6) application server-B initiates to invite request to user C.
7-8) user terminal-C returns success response, carries the media parameter information that it is supported.
9-10) application server-B sends the request that re-invites to user terminal-A, and the media parameter information of user terminal-C is offered user terminal-A, carries out the switching of Media Stream for user terminal-A.
11-12) user terminal-A returns success response, carries the media parameter information that it is supported.
13-14) application server-B confirms replying of user terminal-A.
15-16) application server-B confirms replying of user terminal-C, and the media parameter information of user terminal-A is offered user terminal-C, successfully sets up Media Stream for user terminal-C with user terminal-A and is connected, and user A and user C get final product normal talking.
17) application server-B sends switching notification message, the conversation that user A and user C have been set up in expression to user B.
18) user B returns to application server-B and confirms response.
19) application server-B sends the on-hook request to user B.
18) user B returns to application server-B and confirms response to discharge the conversation between original and the user A.
The present invention also provides a kind of blind transferring operation implement device, comprising: first module, be used for user A and user B at first sets up conversation, and the user B transfer-request that makes a call then requires the conversation of itself and user A is forwarded to user C; Second module, be used to make the application server of user B to receive this call forwarding request after, return acceptance response to user B; It also obtains the media parameter information of user C; It is also to the user A invitation that makes a call, and so that the media parameter information of user C to be provided, indication user A carries out medium and switches, and obtains the media parameter information of user A; With and also provide to user C the media parameter information of user A, indication user C set up with user A between Media Stream be connected; And three module, be used to stop the original conversation of setting up of user A and user B.
There is following defective in first embodiment: call out diversion message if user B has multiple business (as blind transferring operation, convention business etc.) needs to send, and these business are by different application server processes, then the calling diversion message may wrong interception user B sent of application server.
The advantage of second embodiment of the invention is not adopt hold-up interception method, can address the aforementioned drawbacks.The flow chart of the blind transferring operation implementation method of second embodiment is identical with Fig. 5, and the difference part of two embodiment is only in following two steps:
Step S20, the user B transfer-request that makes a call requires to be forwarded to user C; The call forwarding request that user B initiates has different dialogue identifier with the original conversation between user A, the B, the destination address of call forwarding request is the service server of user B, the number information of user C is as the switching destination parameter of call forwarding request, and the dialogue identifier of user A, the original conversation of B is as a parameter of call forwarding request;
Step S30, the application server of user B receives this request, returns acceptance response to user B.
Because the destination address of call forwarding request has been set to the service-specific server that is used for blind transferring operation of user B among the step S20, therefore can not exist the interception of application server mistake to call out the problem of diversion message.
There is another defective in second embodiment: among the step S20 with the dialogue identifier of user A, the original conversation of B a parameter as call forwarding request, but call forwarding request message does not have suitable parameters to can be used for carrying dialogue identifier in the prior art, need expand (as increasing new parameter, changing the implication of existing parameter etc.) to the parameter of call forwarding request message.
The advantage of third embodiment of the invention just is not need to expand the parameter in the call forwarding request message.Fig. 7 is according to the flow chart of the blind transferring operation implementation method of third embodiment of the invention, compares with Fig. 5, changes part and may further comprise the steps:
Step P20, the user B transfer-request that makes a call, this call forwarding request has different dialogue identifier with original conversation between user A, the B, and the destination address of call forwarding request is the service server of user B; The number information of user C is as the switching destination parameter of call forwarding request;
Step P23, the application server of user B is received this request, returns acceptance response to user B;
Step P26, user B initiates the second call forwarding request, and this call forwarding request has identical dialogue identifier with previous call forwarding request, and the destination address of call forwarding request is the service server of user B; The number information of user A is as the switching destination parameter of call forwarding request, and the dialogue identifier of user A, the original conversation of B is as the alternative parameter of call forwarding request;
Step P30, the application server of user B is received this request, returns acceptance response to user B.
Above step is replaced step S20 and the step S30 among Fig. 5, and all the other steps are identical.
The 3rd embodiment utilizes call forwarding request message in the prior art to transmit this professional required parameters fully, does not need to expand.
Among the step S50 or P50 of above-mentioned three embodiment, the application server of user B initiates to call out again to invite to user A; According to the prior art regulation, have only the application server of user B to be on the service message path of the original conversation between user A, the B, the application server of user B could initiate to call out again to invite to user A.Therefore, if the application server that is used for blind transferring operation of user B is not passed through in the original conversation of user A, B when setting up, then step S50 or P50 can't implement.
For addressing the aforementioned drawbacks, the present invention proposes the 4th embodiment.Fig. 8 is (because the step before the S40/P40 of first three embodiment is all applicable to the 4th embodiment according to the local flow chart of the blind transferring operation implementation method of fourth embodiment of the invention, so distinguishing part only is shown here), step S40～S70 among employing following steps replacement Fig. 5 or the step P40～P70 among Fig. 6:
Step Q40, the application server of user B obtain the media parameter information of user C at first to the user C invitation that makes a call;
Step Q50, the application server of user B provide the media parameter information of user C to the user A invitation that makes a call, and indication user A carries out medium and switches, and obtains the media parameter information of user A; During calling out and invite, this also carries the dialogue identifier of user A, the original conversation of B, as calling out the alternative parameter of inviting request, this calls out and invites is that new calling is invited, and does not need the application server of user B to be on the service message path of the original conversation between user A, the B;
Step Q60, the application server of user B provides the media parameter information of user A to user C, indication user C set up with user A between Media Stream be connected;
Step Q70, user A sends the on-hook request according to calling out the alternative parameter information of inviting request among the step Q50 to user B, stops the original conversation of setting up of user A and user B.
Application server is initiated new calling invitation to user A among the 4th embodiment in step Q50, rather than calls out again and invite, and this does not need the application server that is used for blind transferring operation of user B to be positioned at the service message path of user A, the original conversation of user B.
In sum, adopt the present invention program, utilize the application server realizing blind transferring operation, by application server controls invite third party user, to the user circulate a notice of to transfer progress, discharge opportunity (annotate: only the 4th embodiment is still by opportunity of the original conversation of user terminal control release) of original conversation, and need not by forwarded user terminal support call transfer-request, thereby significantly reduced of the dependence of this business, can fully satisfy the demand for control of operator call switching business to user terminal.
