Embodiment one
It is a kind of flow chart of an embodiment of multi-part calling method of the present invention referring to Fig. 2.In the present embodiment, the calling subscribe and/or called subscriber are CAMEL4 contracted users, that is calling subscribe signing CAMEL4 OCSI IN services, and/or called subscriber's signing CAMEL4 TCSI/VTSI IN services, and at least one Multi-Way Calling business is customized in SCP, and it is directed to the corresponding triggering coding of every kind of Multi-Way Calling service subscription justice, then multi-part calling method in the present embodiment, including step：
S201, MSCS are obtained and triggering coding are obtained in the call request sent from caller, and triggering coding is reported into SCP, perform step S203.
In the present embodiment, if calling subscribe will initiate Multi-Way Calling business, then only need to dial the triggering coding pre-defined for such Multi-Way Calling business, (information such as rear subscriber number and the triggering coding of calling user dials can be carried in the call request) to send call request to MSCSA.During specific implementation, triggering coding can be a meeting access code of called number or the MPTY for that will initiate, and can also be the form of meeting access code+called number, certainly, triggering coding can also be self-defined as needed.
In one embodiment, after MSCS receives the call request that calling subscribe sends, it can first verify that whether the calling subscribe is contracted user, if, then trigger intelligent business, will the calling subscribe dialed triggering coding be put into the Called Party BCD Number fields of IDP message, then report to SCP；The MSCS creates call leg CS1 simultaneously, and is respectively that the calling subscribe and triggering coding create the first call instance Leg1 and the second call instance Leg2 in call leg CS1.
S203, MSCS receive multiple operational orders that SCP is issued, and are operated accordingly according to the plurality of operational order, to realize MPTY.
Because contracted user customizes different types of service in SCP, and to trigger corresponding operation flow, (calling subscribe of such as signing can be directed to the MPTY to be initiated and predefine a meeting access code to be encoded as the triggering of triggering " multi-party short calling business ", and all conferenced parties numbers of meeting access code association for the corresponding triggering coding of every kind of service subscription justice；Or, the conference member number of predefined meeting access code+new, or, new meeting member number code book body, triggering coding as triggering " the new conference member business of addition ", wherein, the new conference member number can be defined conference member number when predefining the meeting access code, it may not be), therefore, in the present embodiment, when SCP receives the triggering coding that MSCS is reported, need first to encode the identification for carrying out Multi-Way Calling type of service according to the triggering, then corresponding business is triggered automatically, and multiple operational orders are issued to the MSCS, to indicate that MSCS is operated accordingly according to the plurality of operational order, to realize MPTY.
Specifically, in the present embodiment, step S203 specifically includes step：
1) if current Multi-Way Calling type of service is " multi-party short calling business ", multiple be called is connected by multiple operational orders that MSCS issues according to SCP with caller one by one.
In the present embodiment, when SCP is " multi-party short calling business " according to triggering code identification to go out current Multi-Way Calling type of service, the SCP can be encoded according to the triggering and be issued multiple operational orders to MSCS for each called number, after then MSCS receives the plurality of operational order that SCP is issued, new call instance is created in new call leg for each called number, and the calling established to each call instance, then according to default order, the call leg CS1 being moved to each called corresponding call instance where call instance corresponding to caller one by one, so that caller is connected with multiple be called, realize MPTY.
In one embodiment, the triggering is encoded to a predefined meeting access code, and it associates all conference member numbers, multiple ICA message that then MSCS issues according to SCP for multiple called numbers, it is each called number respectively in different call leg CS2, CS3, ..., CSn, corresponding call instance Leg3 is respectively created, Leg4, ..., Leg i (i=n+1), and the calling established to each call instance, each called conference member is connected, is then back to and acknowledges message to SCP；Issue multiple MoveLeg message further according to SCP, will one by one each call instance from respective call leg CS2, CS3, ..., CSn, the call leg CS1 being moved to where calling subscribe, so that calling subscribe, that is meeting initiator, with each called subscriber, i.e., each conference member, in same call leg CS1, mutually connect, so as to realize MPTY.
Further, because MSCS for each called number before new call instance is created, the called number dialed by calling subscribe, that is triggering coding (i.e. pre-defined meeting access code, rather than a specific user) create a call instance, therefore, the dismantling call operational order that MSCS can be issued first according to SCP is released to the triggering and encodes created call instance Leg2.
2) if current Multi-Way Calling type of service is " the new conference member business of addition ", corresponding new conference member is added in current talking by MSCS according to multiple operational orders that SCP is issued.
In the present embodiment,As the calling subscribe (i.e. meeting initiator) being in call,Or any called subscriber's (i.e. conference member),When the new conference member of desired invitation is added in current talking,Meeting initiator or any conference member, which can pass through, dials triggering coding,And by sending dtmf signal to MSCS to initiate new call request,The triggering coding corresponding to " addition new meeting member business " is then carried in the dtmf signal,And after MSCS receives the call request,ERB message will be reported (to include o-MidCall events in the ERB message,And the second triggering coding is included in the o-MidCall events) to SCP,SCP is then after the Multi-Way Calling type of service corresponding to of the triggering code identification in the ERB message,Corresponding operational order is issued to indicate that MSCS is operated accordingly.
In one embodiment,Triggering coding is the called number (i.e. new conference member number) of a predefined meeting access code+new,Then MSCS acquires the meeting access code and new conference member number from the dtmf signal,And pass through ERB message and the meeting access code and new called number are reported into SCP,Then MSCS will receive ICA message of the SCP for the new conference member number,And a call instance Leg j is created for the new conference member according to the ICA message,And the calling established to Leg j,Connect Leg j,And feeding back response information after connecting,The newly-built Leg j are moved to calling subscribe further according to the MoveLeg message that SCP is issued,That is Leg1,The call leg CS1 at place,So as to realize MPTY.
Certainly, the second triggering coding can also be exactly the number of new meeting member itself.
3) if current Multi-Way Calling type of service is " deleting conference member business ", multiple operational orders that MSCS issues according to SCP delete corresponding conference member from current talking.
In the present embodiment,As the calling subscribe (i.e. meeting initiator) being in MPTY,Or any called subscriber's (i.e. conference member),When wanting to delete any conference member in current talking,Meeting initiator or any conference member can send dtmf signal to initiate new call request by MSCS,And the triggering coding corresponding to " deleting view member business " is carried in the dtmf signal,Then after MSCS receives the call request,The triggering will be reported to encode to SCP,SCP then according to triggering code identification Multi-Way Calling type of service corresponding to after,Corresponding operational order is issued to indicate that MSCS is operated accordingly,That is MSCS is according to the multiple operational orders received,It is released to the call instance that the conference member to be deleted is created,And return to corresponding response message.
In one embodiment, triggering coding is a conference member number being directed in the predefined meeting access code+call of current talking, then MSCS acquires the meeting access code and the conference member number to be deleted from the dtmf signal, and report to SCP, then MSCS will receive the DisconnectLeg message that SCP is directed to the conference member number to be deleted, and be released to the call instance that the conference member to be deleted created according to the DisconnectLeg message.
4) if current Multi-Way Calling type of service is " calling and called normal talking business ", corresponding caller and current be called are connected by MSCS according to multiple operational orders that SCP is issued.
In the present embodiment, the whole process that Multi-Way Calling is established is by interacting to realize between SCP and MSCS, it is only necessary to which calling subscribe initiates call request, calling subscribe is not needed to carry out other troublesome operations, so as to simplify operating process, Consumer's Experience is improved, while also save resource；On the other hand, because called subscriber and calling subscribe converse in call leg CS1, therefore, in addition to meeting initiator, the quantity of conference member can at most increase to 127 each, take full advantage of resource.
In the present embodiment, the step 1) can also carry out independent assortment as needed to being coordination between 4)：Such as, when calling subscribe first initiates MPTY, when i.e. it dials the triggering coding corresponding to multi-party short calling business, MSCS will perform step 1), to realize MPTY, and when the calling subscribe in call or called subscriber continue to initiate call request to invite new conference member to be added in current talking, then MSCS will also perform step 2), similarly, when the calling subscribe in call or called subscriber initiate new call request to delete conference member to MSCS, MSCS will also perform step 3)；Certainly, if first trigger calling and called normal talking business, then caller or the called triggering coding for corresponding to the new conference member of addition by dialing again add new conference member operation flow to trigger, during so as to initiate Multi-Party Conference temporarily, then the MSCS will also perform step 2) after step 1).
Embodiment two
Referring to Fig. 3, for a kind of flow chart of the another embodiment of multi-part calling method of the present invention.Specifically, the multi-part calling method of the present embodiment includes step：
S301, SCP receive the triggering coding that MSCS is reported, and are encoded according to the triggering and carry out Multi-Way Calling type of service identification.
In the present embodiment, triggering coding is obtained in the call request that MSCS initiates from calling subscribe, also include the information such as rear subscriber number and called number in the call request, and after MSCS receives the call request that calling subscribe sends, it can first verify that whether the calling subscribe is contracted user, if so, then trigger intelligent business, coding will be triggered to be put into the Called Party BCD Number fields of IDP message, then report to SCP.
Because contracted user can customize a variety of different types of Multi-Way Calling business simultaneously, and pre-define corresponding triggering for every kind of business to encode, therefore, after the SCP receives the called number, the identification of type of service is first carried out according to the called number, such as：If the triggering is encoded to a predefined meeting access code, understand that corresponding type of service is " multi-party short calling business "；Or if the triggering is encoded to predefined meeting access code+called number, understand corresponding type of service for " addition new meeting member business "；Or if the triggering is encoded to predefined deletion identification code+called number, understand corresponding type of service for " deleting conference member business "；If or the triggering is encoded to specific a certain called number, understand that corresponding type of service is " calling and called normal talking business ".
S303, SCP trigger corresponding operation flow according to recognition result, and issue multiple operational orders to the MSCS, to indicate that it realizes MPTY.
In the present embodiment, if SCP identifies that current Multi-Way Calling business is " multi-party short calling business ", (meeting access code such as associated with multiple called numbers) is encoded according to corresponding triggering and triggers multi-party short calling operation flow；If SCP identifies that for " addition new meeting member business ", (such as meeting access code+called number) triggering addition new meeting member's operation flow is encoded according to corresponding triggering for current Multi-Way Calling business；If SCP identifies current Multi-Way Calling business as " deleting conference member business ", (as deleted identification code+called number) triggering is encoded according to corresponding triggering and deletes conference member operation flow；If or identify that current Multi-Way Calling business is " calling and called normal talking business ", SCP triggering coding triggering calling and called normal talking operation flows corresponding to.Specifically, step S303 includes：
1) when it is " multi-party short calling business " that SCP, which identifies current Multi-Way Calling type of service, then SCP triggerings corresponding to encode, automatically multi-party short calling operation flow is triggered, and it is lower send out operational order multiple respectively to MSCS for each called number, to indicate that MSCS realizes MPTY.
In one embodiment,The triggering is encoded to predefined specific meeting access code,And it associates all conference member numbers,Therefore,After SCP receives the IDP message that MSCS is reported,The number of multiple conference members according to associated by the meeting access code in the IDP message,Multiple ICA message are issued to MSCS,To indicate that the MSCS is each called conference member respectively in different call leg CS2,CS3,…,CSn,Corresponding call instance Leg3 is respectively created,Leg4,…,Leg i (i=n+1),And the calling established to each call instance,Connect each called conference member,Then issue again multiple MoveLeg message indicate the MSCS will one by one each call instance from respective call leg CS2,CS3,…,CSn,The call leg CS1 being moved to where calling subscribe,So that calling subscribe (i.e. meeting initiator) is in same call leg with each called conference member,Mutually connect,So as to realize MPTY.
In the present embodiment, the order that the MSCS moves each call instance can be with self-defined, can also be according to the number order of each call leg.
Due to that can make 128 Leg in call leg CS1 simultaneously while converse, therefore, in the present embodiment, the called conference member can be at most 127, and in other words, above-mentioned Integer n needs to meet condition：128>n>0.
Further, due to while MSCS reports triggering to encode, it is that calling number and triggering coding establish call instance Leg1 and Leg2 respectively in call leg CS1, therefore, in the present embodiment, before the SCP issues ICA message, DisconnectLeg operational orders are first issued to MSCS to indicate that it is released to triggering coding, that is meeting access code, the call instance Leg2 created.
2) when it is " adding new conference member business " that SCP, which identifies current Multi-Way Calling type of service, SCP triggerings corresponding to encode, automatic triggering addition conference member operation flow, and multiple operational orders are issued for the new conference member number, to indicate that new conference member is added in current talking by MSCS.
In the present embodiment, as the meeting initiator to converse, or any conference member is when wanting to invite the new conference member be added in current talking, meeting initiator or any conference member can send dtmf signal to initiate new call request by MSCS, and the triggering coding corresponding to " addition new meeting member business " is carried in the dtmf signal
In one embodiment, triggering coding is predefined meeting access code+called number (i.e. new conference member number), then MSCS acquires the meeting access code and new called number from the dtmf signal, and the meeting access code and new called number are reported to by SCP by ERB message (o-MidCall events are included in the ERB message, and the meeting access code and new called number are included in the o-MidCall events).Then SCP is directed to the new conference member number, issues operational order and indicates that the new called subscriber is added in current talking by the MSCS, so as to realize MPTY, terminates.
3) when it is " deleting conference member business " that SCP, which identifies current Multi-Way Calling type of service, SCP triggerings corresponding to encode, conference member operation flow is deleted in automatic triggering, and multiple operational orders are issued for the conference member to be deleted, delete corresponding conference member to indicate MSCS from current talking.
S311, when it is " calling and called normal talking business " that SCP, which identifies current Multi-Way Calling type of service, then SCP triggerings corresponding to encode, automatically the calling and called normal talking operation flow is triggered, and multiple operational orders are issued to indicate that corresponding caller and current be called are connected by MSCS for the current called subscriber.
In the present embodiment, due to the number that called number is a specific called subscriber (i.e. a conference member), therefore, after SCP receives the IDP message that MSCS is reported, issue Continue message instruction MSCS to continue as the called subscriber, i.e. called number, the second call instance Leg2 created, and connect Leg1 and Leg2 so that calling subscribe (meeting initiator) and called subscriber (conference member) normal talking.
In the present embodiment,The triggering that the calling subscribe is predefined by dialing is encoded to trigger corresponding IN service,Such as pass through and dial meeting access code triggering " multi-party short calling flow ",So that all conference member numbers of the SCP according to associated by meeting access code,Multiple operational order instruction MSCS are issued to connect the related conference member of institute with calling subscribe one by one,So as to realize MPTY,Or,Pass through and constantly dial the called number of meeting access code+new to trigger " addition conference member business ",So that SCP issues corresponding operational order according to the new called number dialed every time,New called subscriber is added in current talking by instruction MSCS one by one,Or,Corresponding operational order is issued to indicate that MSCS deletes the called subscriber from current talking for the called number to trigger " deleting conference member business " SCP by dialing deletion identification code+called number,I.e. whole process is by interacting to realize between SCP and MSCS,Calling subscribe only needs to initiate call request,Calling subscribe is not needed to carry out other troublesome operations,So as to simplify operating process,Improve Consumer's Experience,Also save resource simultaneously；On the other hand, because called subscriber and calling subscribe converse in call leg CS1, therefore, in addition to meeting initiator, the quantity of conference member can at most increase to 127 each, take full advantage of resource.
Certainly, in the present embodiment, other specific codings can also be predefined as needed to trigger corresponding business.
