Control function (Call Session Control Function, CSCF) module, AS.Figure 1B is in the prior art using as schemed
ICS frameworks realization shown in 1A is registered in the process that the calling terminal of circuit domain calls the called end for being registered in LTE network,
Specifically include following steps：
S101：The MSC of calling terminal initiates SRI inquiries to the HLR of called end.
S102：When the HLR discovery called ends of called end have contracted ICS business, indicate that the MSC of calling terminal accesses called end
SCP.
S103：The MSC of calling terminal accesses the SCP of called end.
S104：The SCP instruction MSC of called end will call the MGCF modules/GMSC for being redirected to IMS domain.
S105：The MSC of calling terminal is redirected to MGCF modules/GMSC of IMS domain by calling.
S106：MGCF modules/GMSC routes the call to the CSCF modules of the called end in IMS domain.
S107：The CSCF modules of the called end inquire the location information of the called end in AS.
S108：The location information inquired is returned to MGCF modules/GMSC by the CSCF modules of called end.
S109：MGCF modules/GMSC searches the HLR of called end again.
S110：The HLR of called end determines that called end has been contracted ICS business, and instruction MGCF modules/GMSC accesses called end
SCP。
S111：MGCF modules/GMSC accesses the corresponding SCP of called end, inhibits the redirection function of SCP.
S112：MGCF modules/GMSC completes, subsequently with the connection of called end, to realize that the voice of calling terminal and called end leads to
Letter.
Wherein, if called end be registered in LTE network singly treat LTE terminal, MGCF modules/GMSC passes through called end
CSCF calls called ends, if double standby LTE terminal of the called end to be registered in 2G/3G networks and LTE network simultaneously,
MGCF modules/GMSC can be as needed, passes through the MSC of called end or the CSCF calls called ends of called end.
As it can be seen that the system of above-mentioned business processing, although can solve to be registered in LTE network singly treats LTE terminal as quilt
