Embodiment

The control association relation of setting up of mentioning in the embodiment of the present invention is the address information that refers to an access adaptation unit and CS territory access control function entity and mutually know the other side.The registration in CS territory comprises that the position after the Attach that user starts shooting from shutting down to is upgraded and the position renewal of carrying out across MSC/VLR occurs user.

In following embodiment, be all that hypothesis user does not adhere to (Attach) in CS territory at the beginning, then carry out attaching process and the position updating process in normal CS territory.When user in the time carrying out position renewal can by expansion MAP message (as, MAP_UPDATE_LOCATION message) identifying user place visited place support L-CAAF-n, so that L-CAAF-n is supported in HLR identification visited place, then in issuing data, identifying user is ICS user.

In the embodiment of the present invention one, illustrate how L-CAAF-n knows whether user is ICS user, and idiographic flow as shown in Figure 2, comprises the following steps:

Step s201-step s203, user does not adhere to (Attach) in CS territory at the beginning, then carries out attaching process and the position updating process in normal CS territory.

Step s204, it is ICS user's information that HSS sends user by MAP-Insert-Subscribe-Data message to L-CAAF-n.The method that is specially in MAP-Insert-Subscribe-Data identifying user and is ICS user includes but not limited to following method: a kind of is SS-Code or other applicable fields in MAP_Insert-Subscribe-Data, increase new value, be used for showing that user is ICS user, namely ICS is processed as supplementary service, if L-CAAF-n finds that user has ICS business just to replace user to be registered to IMS, otherwise do not replace user to be registered to IMS; Another kind is to increase new field at MAP_Insert-Subscribe-Data to be used for identifying user be ICS user.

In the present embodiment, if when L-CAAF-n arranges separately, L-CAAF-n need to arrive VLR or HLR(Home Location Register, attaching position register) whether inquiring user be ICS user.If increased new interface between L-CAAF-n and HSS, L-CAAF-n also can obtain by newly-increased interface user's information.L-CAAF-n can simulate existing functional entity, obtains user's CAMEL-Subscription-Information by Cx or SH interface to HSS, and L-CAAF-n can be by the CAMEL-Subscription-Information of SH interface or the subscription of CX interface or inquiring user.In addition, if access adaptation unit has been received the sip message that CS territory control functional entity sends, so just mean that user exists " functional entity is controlled in CS territory ", also just mean that user is ICS user, and then determine to notify CS territory to control the relevant information in functional entity user's CS territory.

In following example, be all take user be ICS user's situation as example, if user is not ICS user, L-CAAF-n only need to, user's message transparent transmission, be processed user's request message by MSC.

In the embodiment of the present invention two, utilize USSD obtain ICCF address method flow as shown in Figure 3 a, comprise the following steps:

Step s301a-s303a, user carries out the position in normal CS territory and upgrades.

Step s305a, L-CAAF-n initiates USSD message, the address that obtains user's ICCF to HSS/HLR.

Step s306a, HSS returns to the address of ICCF to L-CAAF-n by USSD message.Wherein, the ICCF address that HSS returns, can be the address of the user's that configures in HSS ICCF, or HSS be to the address that obtains ICCF after the inquiry of certain fixing place (preserving the database of all users' ICCF address as), is then returning to L-CAAF-n by HSS.

Step s307a, L-CAAF-n sends Info message to ICCF, and notice ICCF user registers in CS territory.In the present embodiment just take send be Info message as example, what L-CAAF-can send may be also Register message etc., and in this Info message, also may carry the address information of L-CAAF-n.

Step s308a, ICCF replaces user to be registered to IMS territory.

Except step s305a to the L-CAAF-n described in step s307a by sending USSD message to HSS obtains inquiry, L-CAAF-n can also directly send USSD message and inquire about its PSI address to ICCF.One of method for routing that it is concrete can be: first the USSD message that L-CAAF-n sends be routed to one has on the entity of distributing USSD message function, owing to being equipped with the address of user ICCF on this entity, therefore can USSD message be specifically routed to by this entity to user's ICCF.Specific implementation process as shown in Figure 3 b, comprises the following steps:

Step s301b-s303b, user carries out the position in normal CS territory and upgrades.

Step s304b, the information that L-CAAF-n discovery user need to adhere to user CS territory is notified ICCF.

Step s305b, L-CAAF-n initiates USSD message, gets its PSI to ICCF, and USSD message is routed to USSD gateway.

Step s306b, USSD gateway is forwarded to USSD message user's ICCF.

Step s307b and step s308b, ICCF returns to the PSI of himself by USSD message.

Step s309b, L-CAAF-n utilizes info message informing ICCF user to register in CS territory.

Step s310b, ICCF replaces user to be registered to IMS.

The query messages just sending take user in the present embodiment as unstructured supplementary data traffic USSD be example, the inquiry such as L-CAAF-N can also use short text SMS in addition, Diameter message.

In the embodiment of the present invention three, can utilize CAMEL to report No. VLR, idiographic flow as shown in Figure 4, comprises the following steps:
