4) when the mobile IMS user of fixing IMS user couple and the shared Mobile Subscriber International ISDN Number of mobile subscriber calls out, professional ability according to portable terminal, audio call should be routed to walking circuit exchange (CS) network, and multimedia calls such as the POC that in the IMS network, continues.But at present, the S-CSCF in the IMS network of prior art can not determine route according to type of service, and it can all be routed to the IMS network with audio call and multimedia call.Yet this moment, called subscriber's ability of support voice business not in the IMS network, therefore, this will cause call failure.At this situation, the present invention can adopt following two kinds of methods to solve.
Scheme one: domain name mapping mode
With reference to Fig. 4 first kind of scheme is described below.
In first step, caller IMS user initiates audio call by called subscriber's E.164 number (MSISDN) to the called subscriber, wherein, and the contracted single number service of IMS network and the shared Mobile Subscriber International ISDN Number of mobile CS network of called subscriber.Indicate this user single number service of having contracted in called subscriber's CAMEL-Subscription-Information, described CAMEL-Subscription-Information is stored among the HSS (home subscriber server).On HSS, disposed simultaneously the iFC (initial filter criteria) of single number service, wherein, pass through iFC, can discern audio call (Circuit Service) and multimedia service (Packet Service), and routing policy is set correspondingly, so that audio call is established in the CS territory, and multimedia service is established in the IMD territory.When the called subscriber registered, iFC was downloaded on its S-CSCF.
In second step, the S-CSCF of calling subscriber's ownership obtains the corresponding SIP URL with the called subscriber by inquiry ENUM dns server, and at this moment, the network supposition thinks that the called subscriber is IMS user.
At third step, the S-CSCF of calling subscriber's ownership routes the call to the S-CSCF of called subscriber's ownership according to called subscriber's SIP URL.
In the 4th step, according to called subscriber's iFC, the S-CSCF of called subscriber's ownership routes the call on the application server (AS) of shared code service.Then, trigger the iFC single number service, and judge that calling out is should to set up or should set up in the CS territory in the IMS territory.For example, the single number service trigger condition in the iFC is set to (Method=" INVITE ") AND (Line=" m " Content=" .*audio.* ").
If, judge and should in the IMS territory, connect, then according to process well known in the prior art, in the IMS territory, connect.Otherwise, should in the CS territory, set up calling if judge, then shared number application server carries out the called number conversion to calling.For example, called number originally is " 12345678@bj.ctcims.cn ", and wherein " " shows to call out and formerly transmitted in the IMS territory before this; Through behind the FH-number transform, described called number can be transformed into " 12345678@bj.umts.cn ", wherein, “ @bj.umts.cn " show that calling will set up in the CS territory.Then, the shared number application server message route that will comprise above-mentioned information is returned the S-CSCF of called subscriber's ownership.
In the 5th step, the S-CSCF of called subscriber's ownership obtains the address of BGCF (Breakout Gateway Control Function) by inquiry DNS, described BGCF address is IP address corresponding with the CS territory in the IMS territory, wherein, in DNS, disposed the address of BGCF corresponding with CS territory (bj.umts.cn territory) in the IMS territory.
In the 6th step, the S-CSCF of called subscriber's ownership routes the call to determined BGCF.
In the 7th step, described BGCF removes domain name among the called subscriber SIP URL (“ @bj.umts.cn "), thereby obtains called subscriber's E.164 number.Then, described BGCF routes the call to MGCF (MGCF), and then is routed to mobile CS network, thereby is addressed to the called subscriber.
Scheme two: coding mode is gone in preceding grafting
With reference to Fig. 5 second kind of scheme is described below.

In second step, the S-CSCF of calling subscriber's ownership obtains the corresponding SIP URL with the called subscriber by inquiry ENUM dns server, and at this moment, the network supposition thinks that the called subscriber is IMS user.
At third step, the S-CSCF of calling subscriber's ownership routes the call to the S-CSCF of called subscriber's ownership according to called subscriber's SIP URL.
In the 4th step, according to called subscriber's iFC, the S-CSCF of called subscriber's ownership routes the call on the application server (AS) of shared code service.Then, trigger the iFC single number service, and judge that calling out is should to set up or should set up in the CS territory in the IMS territory.For example, the single number service trigger condition in the iFC is set to (Method=" INVITE ") AND (Line=" m " Content=" .*audio.* ").
If, judge and should in the IMS territory, connect, then according to process well known in the prior art, in the IMS territory, connect.Otherwise, should in the CS territory, set up calling if judge, then shared number application server carries out the called number conversion to calling.For example, called number originally is " 12345678@bj.ctcims.cn ", and wherein " " shows to call out and formerly transmitted in the IMS territory before this; Through behind the FH-number transform, described called number can be transformed into the Tel URL form of " single number service access code+12345678 ".Then, the shared number application server message route that will comprise above-mentioned information is returned the S-CSCF of called subscriber's ownership.
In the 5th step, the S-CSCF of called subscriber's ownership finds that " single number service access code+12345678 " do not have corresponding SIP URL to exist after inquiring about by ENUM DNS, and then, it routes the call to BGCF.
In the 6th step, BGCF removes described access code from the called number of calling out, route the call to MGCF then.Then, MGCF routes the call to the CS territory again, thereby is addressed to the called subscriber.
