Abstract
The invention discloses an SIP user forced insertion service achievement method based on soft exchange. A user B and a user C are under a calling state, a CS receives an INVITE conversation request that a user A with a forced insertion privilege calls the user B, the INVITE conversation request is launched to the user B, media streams of an MS and the user A are built, ultimately the user A and the user B are in a conversation state, and forced insertion service of the user A is achieved. The method has the advantages that forced insertion and forced releasing services of SIP users are achieved on the basis of SIP protocol signaling; under the condition that a called party is busy, the user with the forced insertion privilege can select forced insertion calling so that the user can communicate with the called party in time, in the service process, a calling user can select whether to carry out forced insertion calling, when the calling user selects the forced insertion calling, the system can play a voice prompt for the calling user and the called user, experience of the users is good and user experience is improved.
Description
Technical field
The present invention relates to a kind of sip user break-in service implementation method based on soft switch, belong to network communications technology field.
Background technology
At present, in soft switchcall server, do not have the calling intrusion implementation based on Session Initiation Protocol, similarly business is waited for for calling out access, but this business is callee side business, in the related service standard of soft switch and in Session Initiation Protocol standard, do not define the break-in service implementation method based on Session Initiation Protocol standard, and in routine work and life, user often can run into while having urgent thing, need notice in time to arrive called, and called may being now in non-important call for a long time, affect the reception and registration of calling party's important thing, such as party A-subscriber calling party B, user B with user C in talking state, system provides a voice message to user A, show that user B is in talking state, system continues, if need to continue to continue, just press certain key, otherwise can select on-hook, party B-subscriber or busy state after a while, system can repeat this prompting process always.
In addition for the break-in service in conventional digital switching system, system is directly carried out forced interposing and forced releasing, whether do not allow user carry out intrusion selects, there is no friendly voice prompt yet, seem more rough, user experiences bad, the scheme that has similar break-in service to realize, business procedure is as follows: party A-subscriber calling party B, user B with user C in talking state, system detects user B and is in talking state, side discharges tolls breakdown user C, succeed user A and B simultaneously, seem not too friendly.
In the call waiting of existing soft switch service, during Called Busy, the new authority of calling out that continues is at callee side, the new calling if callee side is not selected to continue, and calling subscriber has urgent material particular need to notify called subscriber, also cannot be in time and called call.
Summary of the invention
The object of the present invention is to provide a kind of sip user break-in service implementation method based on soft switch, can realize and there is other user of intrusion level and can in the situation that the other side is busy, call out intrusion, time the other side that continues, increase user and experience.
The object of the invention is to be achieved through the following technical solutions: a kind of sip user break-in service implementation method based on soft switch, it comprises following steps:
(1), user B and user C are by call server CS foundation calling, in talking state;
(2), the CS INVITE session request of receiving the user A calling party B with intrusion authority, to user B, initiate INVITE session request;
(2), CS waits in user B response process, while receiving 486 response of user B, to user B, send ACK message, meanwhile, CS detects user A and has break-in service authority, triggers the business of broadcasting by force of calling out;
(3), CS sends a request message to media server MS, MS is to user A playing alert tones in request, and collects user's dialing;
(4), MS receives after playback number-accepting request, minute configuration IVR resource, sends corresponding response message to CS, and according to the SDP information in request message, starts to send voice medium to user A, starts the dialing information that the collection that collects the digits receives user;
(5), CS receives after the response message of MS that the SDP information providing according to MS sends the session request of 200OK response user A;
(6), user A sends ACK message to CS, user A and the foundation of MS media channel, set up the Media Stream of MS and user A;
(7), user A hears after voice message, carry out intrusion button operation, MS detects after the button operation number information of user A, and the information exchange of collecting is crossed to message report CS;
(8), CS receives collecting the digits after information reporting of MS, to MS, send response message, and analyze the subscriber dialing information that MS collects;
(9), the CS dialing information that analyzes user when carrying out break-in service, CS sends BYE to C user, removes C user's call, user C responds 200 message;
(10), CS sends a request message to MS, request MS plays break-in service to user A and carries out warning tone;
(11), MS receives after the playback request of user A, minute configuration IVR resource, sends corresponding response message to CS, starts to send voice medium to user A;
(12), CS sends a request message to MS, carries the SDP information of user B in message, request MS plays break-in service prompt tone to user B;
(13), MS receives that to after the playback request of user B minute configuration IVR resource, to CS transmission response message, starts to user B transmission voice medium;
(14), after CS receives that MS is to the response breath of user B playback request, according to the SDP message in response message, to user B, send re-INVITE message, carry the SDP information that MS provides, request user B carries out media modification operation;
(15), user B receives after re-INVITE request, to CS, sends 200OK response, the media channel foundation of user B and MS, sets up the Media Stream of MS and user B;
(16), after CS receives that user B is to the response of re-INVITE request, to user B, send ACK message;
(17), after prompt tone plays and to finish, CS stops the media play to user A, B to sending message request to MS respectively;
(18), MS receives the media play of user A, B stopped, after request, stopping the media play to user A, B, discharge ivr resource, and give CS response message;
(19), CS receives that IVR stops after response, sends re-INVITE request, the SDP information of carrying user A to user B;
(20), after user B response 200OK, CS sends ACK message to user B;
(21), CS sends re-INVITE request to user A, the SDP information of carrying user B, after user A response 200OK, CS sends ACK message to user A, and so far, user A and user B media channel are set up, user A and user B enter talking state, have realized the break-in service of user A.
Beneficial effect of the present invention is: take by realize the forced interposing and forced releasing business of sip user based on Session Initiation Protocol signaling, realized there is other user of intrusion level can be in the situation that the other side be busy, can select to call out intrusion, to continue in time the other side, and in business procedure, the selection of whether carrying out intrusion is provided to calling subscriber, when calling business user is selected after intrusion, system also can be given calling subscriber and called subscriber's play cuing voice, make user experience close friend, increased user's experience impression.
