Abstract
This invention provides a method for realizing strengthened CW services, in this way, users can transmit operation codes to carry out three-party session or call transfer directly when triggering the CW service and do not exit from the CW service first.
Description
Invention field
The realization of the CW business that the present invention relates to strengthen.
Background technology
Call Waiting (CW, Call Waiting) business is heard CW prompt tone notice when being meant and allowing main controlling user (signatory and activate the user of CW business) to receive third party's incoming call in two square tube words processes.At this moment main controlling user can be selected to answer or ignore from third-party calling.If main controlling user has been replied this calling, main controlling user can be by clicking so
Key carries out handoff calls back and forth between two callings.Schematic flow sheet is seen Fig. 1.
User A is signatory and activate the CW business, and user A and user B are in conversation, and at this moment the state of main controlling user A is 2-way; Third party user C calling party A, (the MSC of mobile switching centre, MobileSwitching Center) can send CW prompt tone notice for user A by issuing Flash With Information message, at this moment the state of main controlling user A be 2-way CW notification; Main controlling user A can be by sending
Key, promptly Kong Flash With Information message is replied, and then user B is held, and main controlling user A and user C can converse, and at this moment the state of main controlling user A is 2-way CW; After this main controlling user A can be by clicking
Key carries out handoff calls back and forth between two callings, with it the other user of conversation keep, recover to converse with maintained user before, the state of main controlling user A still is 2-way CW.In case main controlling user A clicks
The key on-hook then can discharge all-calls branch and user.
After the triggering CW business (2-way CW notification attitude or 2-way CW attitude), even main controlling user A dials TA (Termination Address, destination Mobile Station International ISDN Number)
Key, MSC when handling, will ignore with number, by receiving that empty Flash With Information acknowledgement messaging handles, detailed process is described above, repeats no more here.
Three-Way Calling (3WC, Three-Way Calling) business is meant and allows third party user to add ongoing two square tubes words, carries out Three Party Communication between three members.
For example, the user A 3WC business of having contracted, user A and user B conversation (user A can do caller and also can do called).User A is by dialing " the number of user C
Key " calling party C, after the conversation, A clicks
Key can realize that user A, B, C have carried out the conversation between the three parts.
If any one non-master control side takes out stitches, other two can proceed conversation; If take out stitches in master control side, then other two side all takes out stitches, and discharges this calling.
Schematic flow sheet such as Fig. 2.The user A 3WC business of contracting, user A is by dialing " the number of user B
Key " calling party B, MSC carries out call setup, and in fact this is exactly the process of an ordinary call; User A clicks
Key, MSC are received the Flash With Informat ion message of a sky, and first calling branch is that user B is held; Main controlling user A can dial " the number of user C again
Key " call out third party user C, MSC sets up second calling branch after receiving this Flash WithInformation message; Main controlling user A can click
Key sends Flash With Information message to MSC, and user A, the tripartite user of B, C can converse mutually at this moment, enter the 3WC attitude; When third-party call finished, main controlling user A clicked
Key sends ending request, and MSC discharges all participant members.
Calling transfer (CT, Call Transfer) business is meant that the user of a signatory CT business can transfer to an ongoing calling third party and oneself withdraw from calling, and the calling of incoming call and exhalation can be transferred.
Schematic flow sheet such as Fig. 3.The user A CT business of contracting, front main controlling user are set up the process of first and second calling branch and carry out 3WC similar when professional; Trigger the CT business this moment if desired, and main controlling user A can click
Key sends ending request, and then MSC can discharge main controlling user A, and process user B and user C continue, and user B and user C enter talking state then.
According to top description, about existing ANSI-664 agreement and realization, can obtain following some:
1, CT and CW are separate, when the user who has CT and CW ability does not simultaneously initiate the flash request as yet carrying out two square tubes words, receive third party call, and the user can reply this calling.If this moment, main controlling user was thought diverting call, oneself withdraw from and make other two users set up conversation, must remove Call Waiting branch earlier, recover two square tubes words after, call out third party user again, undertaken by the flow process of setting up of CT;
2,3WC and CW are separate, as the user who has 3WC and CW ability simultaneously, under the situation of receiving third party call, if at this moment send a flash request, will be considered to respond third party call.If in the case, the user desires to carry out 3WC, and then the user also must remove Call Waiting branch earlier, recover two square tubes words after, call out third party user again, undertaken by the flow process of setting up of 3WC;
If 3 users are only signatory and activate the CW business, then can only carry out the CW business, can't carry out calling transfer and Three-Way Calling.
In sum, can have 2 calling branch when carrying out the CW business equally, but no matter be which kind of signatory mode, in case main controlling user triggers the CW business, then can only between two users, select conversation, the user can't carry out calling transfer or Three-Way Calling neatly according to the conversation needs, and obviously this non-user is willing to.
