Abstract
The invention discloses a kind of sip user break-in service implementation method based on soft switch, talking state is in by user B and user C, CS receives the INVITE session requests of the user A calling parties B with intrusion authority, INVITE session requests are initiated to user B, set up the steps such as the Media Stream of MS and user A, end user A and user B enters talking state, realizes the break-in service of user A.The beneficial effects of the invention are as follows：It is taken through being realized based on Session Initiation Protocol signaling the forced interposing and forced releasing business of sip user, realizing the user with intrusion rank can be in the case where other side be busy, can select to carry out calling intrusion, whether so as to the other side that continues in time, and in business procedure, being provided to calling subscribe carries out the selection of intrusion, after calling business user selects intrusion, system can also give calling subscribe and called subscriber's play cuing voice, make Consumer's Experience friendly, and the experience sense that increased user is received.
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 neck
Domain.
Background technology
At present, the calling intrusion implementation of Session Initiation Protocol is not based in soft switchcall server, similar business is calling
Access and wait, but this business is called side business, it is not fixed in the related service specification of soft switch and in Session Initiation Protocol specification
Break-in service implementation method of the justice based on Session Initiation Protocol standard, and in routine work and life, user has been frequently encountered urgent thing
, it is necessary to notify to arrive called in time during feelings, and being called may now be in prolonged insignificant call, and influence calling party is heavy
The reception and registration of thing, such as party A-subscriber calling party B are wanted, user B is in talking state with user C, and system is carried to user A
For a voice message, show that user B is in talking state, system continues, and continues to continue if desired just by certain
Individual key, can otherwise select on-hook, the state that party B-subscriber still hurries after a while, and system can always repeat this prompting process.
In addition for the break-in service in conventional digital exchange system, system directly carries out forced interposing and forced releasing, does not allow user
Carry out whether intrusion is selected, also without friendly voice prompt, it appears relatively more rough, Consumer's Experience is bad, there is similar
The scheme that break-in service is realized, business procedure is as follows:Party A-subscriber calling party B, user B are in talking state with user C
In, system detectio to user B is in talking state, and user C is tolled breakdown in side release, while succeeding user A and B, it appears less friendly
It is good.
In the call waiting of existing soft switch service, during Called Busy, the authority of the new calling that continues in callee side, if
Callee side does not select to continue new calling, and calling subscribe has the urgent material particular to need to notify called subscriber, also cannot in time with quilt
Cry and conversed..
The content of the invention
It is an object of the invention to provide a kind of sip user break-in service implementation method based on soft switch, tool can be realized
The user for having intrusion rank can carry out calling intrusion in the case where other side is busy, when continue other side, increase Consumer's Experience.
The purpose of the present invention is achieved through the following technical solutions：A kind of sip user intrusion industry based on soft switch
Business implementation method, it is comprised the steps of：
（1）, user B and user C by call server CS set up calling, in talking state；
（2）, CS receive the INVITE session requests of the user A calling parties B with intrusion authority, initiated to user B
INVITE session requests；
（2）, CS wait user's B response processes in, receive user B 486 response when, to user B send ACK message, together
When, CS detects user A has break-in service authority, then triggering calling broadcasts business by force；
（3）, CS send request message to media server MS, MS is to user's A playing alert tones for request, and collects user's
Dialing；
（4）, after MS receives playback number-accepting request, distribute IVR resources, send corresponding response message to CS, and according to please
The SDP information in message is sought, starts to send voice medium to user A, startup collects the digits and collects the dialing information of reception user；
（5）, after CS receives the response message of MS, according to the SDP information that MS is provided, send the meeting of 200 OK response users A
Words request；
（6）, user A send ACK message to CS, user A and MS media channels are set up, and set up the Media Stream of MS and user A；
（7）, after user A hears voice message, carry out intrusion button operation, MS detects the button operation number of user A
After information, the information that will be collected into passes through message report CS；
（8）, after CS receives the information report that collects the digits of MS, send response message to MS, and analyze the user that MS is collected into and dial
Number information；
（9）, CS analyze the dialing information of user to perform during break-in service, CS sends BYE to C user, removes C user
Call, user C respond 200 message；
（10）, CS to MS send request message, request MS give user A play break-in service perform warning tone；
（11）, after MS received to the playback of user A request, IVR resources are put in distribution, and corresponding response message is sent to CS,
Start to send voice medium to user A；
（12）, CS send request message to MS, the SDP information of user B is carried in message, request MS plays strong to user B
Insert service informing sound；
（13）, after MS received to the playback of user B request, IVR resources are put in distribution, and response message is sent to CS, start to
User B sends voice medium；
（14）, after CS receives the response breath that MS asked user B playbacks, the SDP message in response message, Xiang Yong
Family B sends re-INVITE message, carries the SDP information that MS is provided, and request user B carries out media modification operation；
（15）, after user B receives re-INVITE requests, send 200 OK to CS and respond, the media channel of user B and MS
Set up, set up the Media Stream of MS and user B；
（16）, after CS receives the response that user B is asked re-INVITE, ACK message is sent to user B；
（17）, prompt tone play after terminating, CS stops broadcasting the media of user A, B to sending message request to MS respectively
Put；
（18）, MS receive after stopping request to the media play of user A, B, stop the media play to user A, B, release
IVR resources, and give CS response messages；
（19）, CS receive after IVR stops response, send re-INVITE to user B and ask, carry the SDP information of user A；
（20）, user B to CS send 200 OK message；
（21）, CS be to send INVITE to user A to ask, then CS just sends ACK message to user B, carries user B's
SDP information, after user A responds 200 OK, CS sends ACK message to user A, and so far, user A sets up with user B media channels,
User A and user B enters talking state, realizes the break-in service of user A.
The beneficial effects of the present invention are：It is taken through being realized based on Session Initiation Protocol signaling the forced interposing and forced releasing industry of sip user
Business, realizing the user with intrusion rank be able to can select to carry out calling intrusion, to connect in time in the case where other side is busy
Continuous other side, and whether in business procedure, being provided to calling subscribe carries out the selection of intrusion, when calling business user selection is strong
After inserting, system can also give calling subscribe and called subscriber's play cuing voice, make Consumer's Experience friendly, increased the experience of user
Impression.
