UE is when EPS network insertion, basic speech business and the supplementary service based on speech business of user are by operator's IP network, such as IP Multimedia System (IMS, IPMultimediaCoreNetworkSubsystem) control, EPS itself can not provide and control voice call service, can only provide the carrying of IP data.Here, for IMS, IMS is the IP-based network architecture of the one proposed by 3GPP, and it constructs an opening and service environment flexibly, supports multimedia application, and provides the user abundant multimedia service.IMS is IP-based communication network framework, unrelated with access technology, except being EPS, GPRS (general packet radio service) (GPRS, GeneralPacketRadioService), outside the packet access network offer business such as WLAN, it can also be the CS networks offer services of the mobile cellular network such as GSM, UMTS (UMTS, UniversalMobileTelecommunicationsSystem).Wherein, Internet protocol represents with InternetProtocol, is abbreviated as IP.
It is illustrated in figure 2 single wireless channel under prior art and accesses the selection flow process of bimodulus UE end call network, GMSC receives far-end address initial message, obtains route to HSS, and at this time UE may register in IMS network and CS network, such as UE is first after IMS registration is complete, moving to CS network register, HSS begins to exhale according to carrier policy, one network of prioritizing selection, the most first select IMS network, when, after call attempt failure, selecting another one network to re-start call attempt, specifically comprise the following steps that
Step 201, GMSC receive the address initial message that remote equipment (Remote) is sent, and set up call request message, carry called number in call request message.
Step 202, receiving call request message, GMSC sends route request information according to the called number parsed from call request message, the HSS belonging to called, obtains the routing iinformation that called subscriber is current.
Step 203, HSS select service network after receiving route request information, it is judged that active user is when IMS network and CS network have succeeded in registration, and HSS services as service network according to migration efficiency prioritizing selection IMS network.
Step 204, HSS return the route requests response message comprising IMS routing number to GMSC.
Step 205, GMSC, according to IMS routing number, send session invitation message to IMS network, route calls to IMS network.
Step 206, IMS network send session invitation message to UE.
Step 207, UE be not the most in IMS network, and IMS waits UE response time-out.
Step 208, IMS network return session invitation failed message to GMSC, indicate called subscriber's nonreply.
If step 209 GMSC in 204 steps does not receive the routing iinformation of CS network, then need to carry out rerouting process, it may be assumed that GMSC needs again to send route request information to HSS, in order to obtain CS domain routing number.
Step 210, GMSC, according to CS domain routing number, send address initial message to target MSC.
Step 211, target MSC receive address initial message, carry out paging called, to called transmission call setup request message.
