Fig. 2 is the realization flow diagram of the simultaneous ringing service after optimization provided in an embodiment of the present invention, as shown in Fig. 2, should
Flow includes the following steps：
Step 201：Receive the call request of calling subscribe.
Here, the calling subscribe initiates calling to the called subscriber for having opened one number service simultaneous ringing service；Wherein, it is described to open
The called subscriber for having led to one number service simultaneous ringing service includes a major number, and the major number is bundled with multiple sub- numbers.
Step 202：Judge whether the sub- number of called major number and its binding is completely in busy state, if so,
Perform step 205；Otherwise, step 203 is performed.
Here, after the call request for receiving calling subscribe, the institute of called major number and its sub- number of binding is first inquired
Then place's state is judged to whether the sub- number for being called major number and its binding is completely in busy state, in order to
Calling decision is carried out according to condition adjudgement result：If the status of called major number and its sub- number of binding is all non-empty
Not busy state performs step 205, the calling for the called major number that only continues；If the institute of called major number and its sub- number of binding

Step 203：Whether the number for judging to be in idle condition is same type, if so, performing step 206；Otherwise,
Perform step 204.
Here, to same type of number, while replay call；To different types of number, timesharing replay call.
Step 204：Calling is issued immediately to the CS domains Subscriber Number being in idle condition, to being in the IMS domain of Idle state
Subscriber Number delay sending calls, and terminates currently processed flow later.
Here it is possible to the IMS domain user delay sending for being in Idle state is called using delayer, i.e.,：It is in all
The IMS domain Subscriber Number of Idle state starts the delayer of N seconds, again to the IMS domain Subscriber Number in Idle state after N seconds
Carry out call proceeding.
Here, N values can show that details are not described herein by specifically testing.
Step 205：Only continue the calling of called major number, terminates currently processed flow later.
Step 206：Continue the calling of number being in idle condition simultaneously.
In the present embodiment, the executive agent of step 201~step 206 all can be application server.
In the following, one number service simultaneous ringing service is opened with CS domains common subscriber number A callings and has been bundled with IMS domain C numbers
For the one number service major number of a subscriber B of CS domains, to illustrate the signaling process of the one number service simultaneous ringing service after optimization.In simple terms, A is
Rear subscriber number；B is called major number and B belongs to CS domains Subscriber Number；C is to belong to IMS domain user by whistle number and C
Number.
Fig. 3 is the signaling process schematic diagram of the simultaneous ringing service after optimization provided in an embodiment of the present invention, as shown in figure 3, should
Signaling process includes the following steps：
Step 301：Mobile switching centre（MSC, Mobile Switching Center）To call session control function
（CSCF, Call Session Control Function）The request that entity sends the called major number B of calling subscribe A callings disappears
Breath.
In practical application, when describing signaling, usually use "（A->B）" represent A callings B；With " INVITE（A->B）" represent
A request calls B；With " CANCEL（A->B）" represent to cancel callings of the A to B；With " SEQ INVITE（A->B）" represent to continue A pairs
The calling of B；It is responded successfully with " 200OK " expression；With " REQ Usrinf（A）" represent to inquire the state of A；With " RES Usrinf
（A）" represent to return to the status inquiry result of A.
Therefore, " INVITE is used in figure 3（A->B）" represent that calling subscribe's A request calls are called major number B.
Here, the MSC can also use Gateway Mobile Switching Center（GMSC, Gateway Mobile Switching
Center）Or Media Gateway Control Function（MGCF, Media Gateway Control Function）To replace.
Step 302：CSCF entities forward the request message of the called major number B of calling subscribe A callings to AS.
Here, the AS can also use service control point（SCP, Service Control Point）To substitute.
Step 303：State from AS to CSCF object query numbers C, to home location register（HLR, Home
Location Register）The state of enquiry number B.
Specifically, the flow of AS to the state of CSCF object query numbers C mainly includes the following steps that：
303a：AS sends the request for being presently in state of enquiry number C to CSCF entities, for example, using " REQ in figure 3
Usrinf（C）" represent.
303b：The request that CSCF entities return to the inquiry state about number C to AS responds, for example, using " RES in figure 3
Usrinf（C）" represent.
Specifically, the flow of AS to the state of HLR enquiry numbers B mainly includes the following steps that：
303c：AS sends the request for being presently in state of enquiry number B to HLR, for example, using " REQ in figure 3
Usrinf（B）" represent.
303d：The request that HLR returns to the inquiry state about number B to AS responds, for example, using " RES in figure 3
Usrinf（B）" represent.
Step 304：AS determines to issue the strategy of calling according to the state and type of number B and number C.
It is assumed that the state of number B and number C are idle state, then, AS determines to issue and exhale to number B and number C
It cries；Because number B belongs to CS domains Subscriber Number, number C belongs to IMS domain Subscriber Number, exhaled so AS determines first to issue to number B
It cries.Idiographic flow can be represented with 304a~304e.
304a：AS issues the number A that continues to CSCF entities to the request of the calling of number B, for example, using " SEQ in figure 3
INVITE（A->B）" represent.
304b：CSCF entities to MSC forward described in continue number A to the request of the calling of number B.
Here, after preset time, AS sends out the number A that continues to the request of the calling of number C to CSCF entities again, so as to
Terminal can ring simultaneously where terminal where number B and number C.
Wherein, the preset time can be set according to actual conditions.
304c：AS issues the number A that continues to CSCF entities to the request of the calling of number C, for example, using " SEQ in figure 3
INVITE（A->C）" represent.
The sequence of above-mentioned steps 304b and 304c can be interchanged.
304d~304e：CSCF returns to the success response that continues of number C to AS, and MSC returns to the success that continues of number B to AS
Response.
In figure 3, CSCF entities return to success response and MSC the connecing to AS return number B of continuing of number C to AS
Continuous success response, is represented with common form of presentation " 200OK ".
Here, CSCF entities return to continue success response and continue successes of the MSC to AS return numbers B of number C to AS
The time difference of response is less than given threshold, when the time difference being less than given threshold, is perceived for angle from user, number C
Place terminal and terminal ring simultaneously where number B.
The terminal where the number B checks numbers the calling of A when responding, and performs step 305.
Step 305：Discharge the calling for the C that checks numbers.
When that is, the terminal where the number B is checked numbers, the calling of A responds, AS releases are checked numbers the calling of C,
Terminal stops ring where number C.
Here, the check numbers flow of the calling of C of AS release mainly includes the following steps that：
305a：AS sends the request for the calling for discharging the C that checks numbers to CSCF entities, for example, using " CANCEL in figure 3（A-
>C）" represent.
305b：CSCF entities return to request success response to AS.
In above-mentioned signaling process, subsequent request is issued for different type user time-sharing, has been evaded because accessing side reason
Caused called terminal can not simultaneously ring the defects of, improve user experience.
