It is understood that the VMSC data volumes of the whole network are huge.And, during ICS deployment, the upgrading of VMSC is progressively carried out, therefore
Need often to update the data in HLR, be unfavorable for safeguarding data.Therefore, the ICS systems are being safeguarded and are using HLR completion triggerings
When EMSC proxy users carry out IMS registration, can cause to safeguard complicated.
Secondly, ICS systems CS domains complete location updating after, EMSC proxy users carry out IMS registration before just by CS
Domain attachment response message issues UE.Think that the attachment of CS domains is completed after receiving CS domains attachment response message due to user, if vertical
I.e. initiate calling, now IMS registration do not complete, although the calling still can be continued in CS domains, but be desirable with ICS
Technology, CS user is linked into the original intention being controlled in IMS and is not inconsistent, it is impossible to make full use of IMS network.
In order to solve the above mentioned problem of prior art, this patent proposes a kind of improved novel I C/S system and its use
Family register method.

Specific embodiment
With reference to the accompanying drawings, presently filed embodiment is described in detail.
Fig. 2 shows the structure chart of the ICS systems 100 according to presently filed embodiment.ICS systems according to the application
100 include VMSC 101, EMSC 102, HLR 103 and STP (Signaling Transfer Point, Signalling Transfer Point)
104.In addition to HLR 103 and STP 104, the function of the miscellaneous equipment in ICS systems 100 with No. 201010614929.5
The function phase of relevant device is same in Chinese patent application, repeats no more here.
In presently filed embodiment, the function of HLR 103 is same with the original HLR function phases in CS networks, i.e., do not have
Having triggering EMSC proxy users carries out the function of IMS registration.Conversely, STP 104 with its original function such as signaling except passing
Send, signal switching, GT translation, outside the function such as GT numbers match, signaling network routing management, route backup, load sharing, also have
Having suspended position to update response and the triggering proxy users of EMSC 102 carries out the function of IMS registration.
Fig. 3 shows the functional block diagram of the STP 104 in the ICS systems 100 shown in Fig. 2.
As shown in figure 3, STP 104 includes signaling detection module 1041 and triggering IMS registration module 1042.
In ICS systems 100, when user sends CS domain attach requests to VMSC 101, VMSC 101 passes through STP 104
User authentication and location updating are carried out with HLR 103.In this case, when STP 104 is receiving the location updating in CS domains
During response, the response of the 1041 pairs of location updatings of signaling detection module is detected, if detect user contracted ICS business,
The VMSC addresses in location updating response are then detected, EMSC addresses are then derived according to VMSC addresses.
Then, according to the detection of signaling detection module 1041, triggering the agencies of EMSC 102 use triggering IMS registration module 1042
Family carries out IMS registration.
Because STP 104 is being triggered before the proxy users of EMSC 102 carry out IMS registration, it is necessary to be derived according to VMSC addresses
EMSC addresses, therefore STP 104 is also configured with the data of the corresponding relation of VMSC and EMSC in managed VMSC packets.
However, with No. 201010614929.5 Chinese patent application in have Trigger Function HLR in configuration data
Amount is compared, and STP 104 only needs to configure the VMSC data corresponding with EMSC of a certain region (such as one province) so that its configuration
Amount greatly reduces.Further, since the quantity of STP will also be considerably less than the quantity of HLR, therefore cost can be greatly reduced.
In alternative embodiments, because in existing network, VMSC and HLR is direct-connected and VMSC is by STP and HLR
Two kinds of networkings of connection are simultaneously deposited；Therefore, under this networking, selectively HLR and STP can be upgraded with above-mentioned triggering
Function.In one embodiment, HLR only configures the corresponding relation of the VMSC direct-connected with it and EMSC；And STP configurations and its phase
The corresponding relation of VMSC even and EMSC.
In presently filed embodiment, the STP 104 of ICS systems 100 may also include timer module 1043 and suspension
Module 1044.
Timer module 1043 is when the triggering proxy users of EMSC 102 of triggering IMS registration module 1043 carry out IMS registration
Start timer to wait IMS registration to complete confirmation message；And when STP 104 receives IMS registration completion confirmation message
Stop timer.
Suspending module 1044 detects user and has contracted after ICS business in signaling detection module 1041, and suspended position is more
New response；And after EMSC 102 carries out IMS registration completion, the location updating response that will be suspended is sent to VMSC 101.
Wherein, after the proxy users of EMSC 102 carry out IMS registration completion, IMS registration can be sent to STP 104 and completes confirmation message.
According to STP as described above 104, after EMSC proxy users complete IMS registration, then inform that user completes
CS domains are registered, and user initiates calling immediately after the registration of CS domains is completed in can avoiding No. 201010614929.5 patent application
Caused calling can still be carried out in CS domains, it is impossible in the problem that IMS continues.
And, even if after the timer expiry that timer module 1043 is started, STP 104 does not receive IMS yet
Registration completes confirmation message, and suspending module 1044 will return to the response of the location updating of suspension and the CS message that succeeds in registration
User, such user still can initiate to call in CS domains.
Fig. 4 shows the flow chart of the user registering method 200 realized by above-mentioned ICS systems 100.
In the user registering method 200 of ICS systems 100, when the CS domains attachment that VMSC 101 receives user's transmission please
When asking, VMSC 101 and HLR 103 carries out user authentication and location updating (step S202) by STP 104.
In step S204, HLR 103 sends to STP 104 the location updating response in CS domains.In step S206,
STP 104 detects whether user has contracted ICS business in location updating response.If detecting user in step S206
Contract ICS business, then STP 104 detects VMSC addresses in location updating response, and according to the VMSC addresses for detecting
Derive EMSC addresses (step S208)；Otherwise, method 200 terminates.
Then, in step S210, STP 104 triggers the proxy users of EMSC 102 and carries out IMS registration according to EMSC addresses.
In step S212, EMSC 102 derives IMS home domain and ID and proxy user and carries out IMS registration, is then noted in IMS
After volume is completed, send IMS registration to STP 104 and complete confirmation message.
In alternative embodiments, STP 104 suspends location updating response after location updating response is received
(step S205).Additionally, while STP 104 carries out IMS registration according to the EMSC addresses triggering proxy users of EMSC 102,
STP 104 starts timer to wait IMS registration to complete confirmation message (step S211).Then, STP104 is come from receiving
The IMS registration of EMSC 102 is completed after confirmation message, and the location updating response that stop the timer and will suspend sends extremely
VMSC 101, the attachment response of CS domains is sent with to user, informs that the attachment of user CS domains completes (step S213).
