Step 303, the location update request message received is converted to SIP registration message by ICS MSC Server, user attaching domain name is obtained according to identify label IMSI, registration message is sent to UE home domain IMS network entrance network element I-CSCF, the private user identity (PVI, Private User Identity) derived according to the IMSI of UE by ICS MSC Server is carried in registration message.
Step 304, I-CSCF receives registration message, inquires about login state, carry the PVI of UE in message to HSS.HSS searches present terminal login state according to the PVI of UE, if re-injection volume, then return UE with the S-CSCF address of registration, if register first, HSS selects a S-CSCF address or returns a S-CSCF capabilities list;
Step 305, if HSS returns is S-CSCF address information, then I-CSCF forwards login request message to this S-CSCF, if the S-CSCF capabilities list that HSS returns, then I-CSCF selects the S-CSCF that an ability meets, and forwards login request message to it;
Step 306, S-CSCF receives login request message, may trigger authorizing procedure, for simplicity's sake, wouldn't too much describe here;
Step 307, S-CSCF obtains customer service subscription data to HSS;
Step 308, S-CSCF returns to mAGCF the message that succeeds in registration, and carries available public subscriber identification (PUI, the Public User Identity) list of UE and default PUI in message;
Step 309, mAGCF preserves S-CFCF address and user ID list and default PUI, and is updated successfully message to UE home position;
In ICS enhancing technology, MSC function is weakened, no longer there is service processing function, only be responsible for protocol conversion and Resource Management, business triggers and controls all to focus on ownership IMS core network, and for conventional CS network roaming mechanism, Service control and triggering are by visited place MSC process, technology is strengthened like this according to existing ICS, time in the network causing legacy user to roam into describing in background technology, cannot trigger business.
