Step 6, described SCP instruction are carried out call business in the CS territory and are continued, and finish and call out the back end.
Because in the call business that initiate in the CS territory, voice class professional with information series business respectively by different gateway processes, so be further divided into two kinds of situations:
A kind of situation is: when call business described in the step 1 was audio call, described SCP received the call request that MSC sends.For example, the terminal initiating speech conversation in CS territory, SCP inquires under the situation that terminal called all registers in CS territory and IMS territory simultaneously, default network selection policy information among the inquiry HSS, because voice call effect in the CS territory is better, therefore the strategy of operator's setting is that handle in the CS territory, and then SCP directly returns route instruction and gives MSC, is established to the calling of terminal called in the CS territory by MSC.
But when called initiation be visual voice call the time because the effect of visualization that the IMS territory provides is better, therefore may the user sets strategy especially and be the processing of IMS territory, then described step 5 is specially:
Step 51a, described SCP generate special IMS territory number, carry the E.164 number of described different field general terminal in the number of described special IMS territory;
The route instruction that step 52a, described SCP will point to described special IMS territory number sends to MSC;
Step 53a, described MSC are routed to MGCF/MGW according to described route instruction with call business;
Step 54a, described MGCF/MGW extract the E.164 number of described different field general terminal from described special IMS territory number, and send to S-CSCF;
Step 55a, described S-CSCF E.164 number resolve to SIP URI number, and are established to the calling of described different field general terminal;
After step 56a, calling are finished, finish.
Another situation is that when the call business in the described step 1 was information series business, described SCP received the call request that SMS/MMS sends.For example, the terminal when the CS territory sends note to terminal called, is to report SCP by SMS.
SCP inquires under the situation that terminal called all registers in CS territory and IMS territory simultaneously, default network selection policy information among the inquiry HSS, because short message service just can access good support in the CS territory, therefore static policies is handled for the CS territory, then SCP directly returns route instruction and gives SMS, in the CS territory short message is sent to different field general terminal by SMS.
But when called initiation be multi-media SMS when professional because the multimedia support that the IMS territory provides is abundanter, so operator sets strategy and is the processing of IMS territory, then described step 5 is specially:
Step 51b, described SCP generate special IMS territory number, carry the E.164 number of described different field general terminal in the number of described special IMS territory;
The route instruction that step 52b, described SCP will point to described special IMS territory number sends to SMS/MMS;
Step 53b, described SMS/MMS are routed to the IM/POC server according to described route instruction with call business;
Step 54b, described IM/POC server extract the E.164 number of described different field general terminal, and send to S-CSCF from described special IMS territory number;
Step 55b, described S-CSCF E.164 number resolve to SIP URI number, and are established to the calling of described different field general terminal;
After step 56b, calling are finished, finish.
Referring to Fig. 6, for when the method for calling of IMS territory terminal when different field general terminal makes a call business, may further comprise the steps:
Step 1 ', the S-CSCF of described IMS territory terminal sends to the network selection application server with call request;
Step 2 ', described network selection application server inquires about described different field general terminal whether in the registration of IMS territory, be then execution in step 3 ', otherwise execution in step 5 ';
Step 3 ', described network selection application server inquires about described different field general terminal whether in the registration of CS territory, be then execution in step 4 ', otherwise execution in step 7 ';
Step 4 ', default network selection policy information among the described network selection application server inquiry HSS, and determine the network selection mode of described call business, during for CS territory network selection mode, execution in step 5 ', otherwise execution in step 7 ';
Step 5 ', described network selection application server generates special CS territory number, sends to described S-CSCF, carries the E.164 number of described different field general terminal in the number of described special CS territory;
Step 6 ', described S-CSCF is according to described special CS territory number, and call business is routed to the CS territory, finish to call out the back and finish;
Step 7 ', the described S-CSCF of described network selection application server instructions carries out call business in the IMS territory and continues, finish to call out the back and finish.
Because in the call business that initiate in the IMS territory, voice class professional with information series business also respectively by different gateway processes, so be divided into two kinds of situations equally:
When described call business is the voice class business, described step 6 ' be specially:
The route instruction that step 61a ', described S-CSCF will point to described special CS territory number sends to MGCF/MGW;
Step 62a ', described MGCF/MGW extract the E.164 number of described different field general terminal from described special CS territory number, call business is routed to MSC;
Step 63a ', MSC are established to the calling of described different field general terminal according to described E.164 number;
After step 64a ', calling are finished, finish.
When described call business is information series business, described step 6 ' be specially:
The route instruction that step 61b ', described S-CSCF will point to described special CS territory number sends to the IM/POC server;
Step 62b ', described IM/POC server extract the E.164 number of described different field general terminal from described special CS territory number, call business is routed to SMS/MMS;
Step 63b ', SMS/MMS are established to the calling of described different field general terminal according to described E.164 number;
After step 64b ', calling are finished, finish.
Because when the user inserts the use of IMS territory, the regular traffic function that possesses common IMS territory terminal, when the user inserts the use of CS territory, the regular traffic function that possesses common CS territory terminal, therefore, if different field general terminal is only registered in a territory, then communication mode is in the conventional territory or inter-domain communication, repeats no more here.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
