Abstract
Description
Technical field
The present invention relates to the communications field, more specifically, relate to and be used for for example the enquiry switching service implementation method and the device 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 shows the schematic diagram of realizing framework according to a kind of typical services in the next generation network of prior art.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 shows the signaling process figure of the inquiry transferring flow process 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 the calling hold mode then, then user terminal-B initiate to have set up and user terminal-C between the conversation speech channel, (application server-C) has all participated in this communication process to the application server of application server-B and user terminal-C; By user terminal-B user terminal-C is changed to the calling hold mode then, sends a transfer-request (step 1～3) to user terminal-A again; After user terminal-A represents to accept this request (step 4～6), send the request of inviting to user terminal-C (user C) and (carry correlated identities in this request, the conversation of having set up between indicating user terminal-C alternate user terminal-B and the user terminal-C), between user terminal-A and user terminal-C, set up conversation (step 13～24); User terminal-C sends the on-hook request to disconnect the speech channel (step 25～30) between original users terminal-C and the user terminal-B according to the identification information of inviting in the request to user terminal-B; 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 7～12, step 31～36); At last, user terminal-B sends the on-hook request to user terminal-A, disconnects the speech channel (step 37～42) between original users terminal-A and the user terminal-B.
A distinguishing feature of above flow process is, 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 is inconsistent, 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 limitation and hidden danger.Therefore, operator wishes to strengthen the control to call switching business.

Fig. 4 shows the flow chart according to the enquiry switching service implementation method of first embodiment of the invention, may further comprise the steps:
Step S10, user A and user B at first set up conversation;
Step S20, user B and user C set up conversation;
Step S30, the user B transfer-request that makes a call requires the conversation of itself and user A is forwarded to user C, and replaces the conversation between itself and the user C; The call forwarding request that user B initiates has identical dialogue identifier with the original conversation between user A, the B, call forwarding request will arrive the application server of user B along the service message path of original conversation, the number information of user C is as the switching destination parameter in the call forwarding request, and the dialogue identifier of user B, the original conversation of C is as the alternative parameter in the call forwarding request;
Step S40, the application server of user B is received this request, returns acceptance response to user B;
Step S50, the application server of user B at first initiate to call out again to invite to user C, obtain the media parameter information of user C;
Step S60, the application server of user B initiates to call out again to invite to user A, and the media parameter information of user C is provided, and indication user A carries out medium and switches, and obtains the media parameter information of user A;
Step S70, 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 S80, the application server of user B sends the on-hook request to user B, stops the original conversation of setting up of user B and user C;
Step S90, the application server of user B sends the on-hook request to user B, stops the original conversation of setting up of user A and user B.
Further, said method also can may further comprise the steps: user B calls out maintenance to the conversation between user A and the user B earlier before setting up conversation with user C, temporarily interrupt the Media Stream between user A and the user B;
Further, said method also can may further comprise the steps: user B calls out maintenance to the conversation between user B and the user C earlier before the transfer-request that makes a call, temporarily interrupt the Media Stream between user B and the user C.
Further, said method also can may further comprise the steps: the application server of user B can successfully be set up conversation to user B circular user A and user C before indication user B on-hook.
Further, said method also can may further comprise the steps: the application server of user B can be to user B report call switching well afoot behind the call forwarding request of accepting user B.
Further, said method also can have following characteristics: the application server of user B can judge whether user B has the authority of the switching of making a call according to the service log-on information of user B among the step S40, if user B does not have authority, then application server returns the refusal response to user B.
There is following defective in first embodiment: call out diversion message if user B has multiple business (as enquiry switching service, 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 enquiry switching service implementation method of second embodiment is identical with Fig. 4, and the difference part of two embodiment is only in following two steps:
Step S30, the user B transfer-request that makes a call requires to be forwarded to user C, and replaces the conversation between itself and the 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 application server of user B, the number information of user C is as the switching destination parameter of call forwarding request, the dialogue identifier of user B, the original conversation of C is as the alternative parameter in the call forwarding request, and the dialogue identifier of user A, the original conversation of B is as a parameter of call forwarding request;
Step S40, 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 specific application servers that is used for enquiry switching service of user B among the step S30, therefore can not exist the interception of application server mistake to call out the problem of diversion message.
The defective that second embodiment exists is: among the step S30 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. 5 is according to the flow chart of the enquiry switching service implementation method of third embodiment of the invention, compares with Fig. 4, changes part and may further comprise the steps:
Step P30, 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 application 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 B, the original conversation of C is as the alternative parameter in the call forwarding request;
Step P33, the application server of user B is received this request, returns acceptance response to user B;
Step P36, 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 application 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 P40, the application server of user B is received this request, returns acceptance response to user B.
Above step is replaced the step S30～step S40 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 C; 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 B, the C, the application server of user B could initiate to call out again to invite to user C.Therefore, if the application server that is used for enquiry switching service of user B is not passed through in the original conversation of user B, C when setting up, then step S50 or P50 can't implement.
Similarly, among the step S60 or P60 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 enquiry switching service of user B is not passed through in the original conversation of user A, B when setting up, then step S60 or P60 can't implement.
For addressing the aforementioned drawbacks, the present invention proposes the 4th embodiment.Fig. 6 is that (step before the S50/P50 of first three embodiment is all applicable to the 4th embodiment according to the local flow chart of the call switching business implementation method of fourth embodiment of the invention, for the sake of brevity, here no longer be repeated in this description), step S50～S70 among employing following steps replacement Fig. 5 or the step P50～P70 among Fig. 6:
Step Q50, 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; This call out to invite the dialogue identifier of carrying original conversation between user B, the C simultaneously, and indication user C replaces the conversation between itself and the user B; Should be noted that it is that new calling is invited that this 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 B, the C;
Step Q60, 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; Should be noted that it is that new calling is invited that this 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 B, the C;
Step Q70, 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 Q75, user C 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 B and user C;
Step Q80, user A sends the on-hook request according to calling out the alternative parameter information of inviting request among the step Q60 to user B, stops the original conversation of setting up of user A and user B.
Annotate: step Q75 and step Q80 do not have inevitable sequencing relation.
Application server is initiated new calling invitation to user C among the 4th embodiment in step Q50, rather than call out again and invite, this does not need the application server that is used for call switching business of user B to be positioned at the service message path of user B, the original conversation of user C.
Application server is initiated new calling invitation to user A among the 4th embodiment in step Q60, rather than call out again and invite, this does not need the application server that is used for call switching business of user B to be positioned at the service message path of user A, the original conversation of user B.
The defective of the 4th embodiment is that the termination of user B, the original conversation of user C need be initiated by user C, and the termination of user A, the original conversation of user B need be initiated by user A, and the opportunity that promptly discharges original conversation can not be by application server controls.
The first/two/three embodiment can be combined with the 4th embodiment during concrete enforcement, that is: at step S50/P50/Q50 place, by application server judge self whether to be positioned at user B, on the service message path of the original conversation of user C, if then application server sends the request (follow procedures S50/P50) that re-invites to user C; If not then application server sends the new invitation request (follow procedures Q50) of carrying alternative parameter to user C.Similarly, at step S60/P60/Q60 place, judge that by application server self is whether on the service message path of original conversation between user A, the user B, if then application server sends the request (follow procedures S60/P60) that re-invites to user A; If not then application server sends the new invitation request (follow procedures Q60) of carrying alternative parameter to user A.
