In the IMS calling procedure, S-CSCF is the Invite message that carries ICP information to the AS forwarding.
Step 208:AS returns register response to S-CSCF, such as sending " 200OK " message.
Step 209:AS will carry ICP notification of information message and send to SGSN, such as when SGSN does not support the IMS signaling, send Insert Subscriber Data (insertion user data) message that carries ICP information; Or when SGSN supports the IMS signaling, send Publish (issue) message or Options (option) message that carry ICP information.
Step 210:SGSN notifies the ICP information that obtains to base station sub-system, carries Common ID (public identifier) message of ICP information such as transmission.
Step 211:UE sends call request in the CS territory to MSC, such as sending Setup (foundation) message.
Step 212: after receiving call request, base station sub-system is transmitted another call request to MSC, carries ICP information in this another call request.
So far, MSC has obtained ICP information.
Step 213:MSC sends call request according to ICP information to ICP, such as when MSC does not support the IMS signaling, sends IAM (Initial Address Message, initial address message); Or when MSC supports the IMS signaling, send Invite message.
Step 214:ICP continues follow-up IMS calling procedure.
After step 215:ICP receives called replying, send call,, send ANM (Answer Message, response message) such as when MSC does not support the IMS signaling to MSC; Or when MSC supports the IMS signaling, send " 200OK " message.
Can find out by step 213-215, when MSC does not support the IMS signaling, can carry out interacting message with common signaling message and ICP; When MSC supports the IMS signaling, can carry out interacting message with IMS signaling and ICP.
Step 216-217:MSC sends call via base station sub-system to UE, such as sending Connect (connection) message, this Connect message travels base station sub-system.
If ICP is on AS, the ICP information that then AS sends to SGSN in the step 209 is generated by AS, rather than is transmitted by S-CSCF, and step 202-208 becomes:
Register requirement is by way of P-CSCF, and P-CSCF is transmitted to S-CSCF with register requirement;
S-CSCF allows UE to insert the IMS network, then return register response, such as sending " 200OK " message;
After P-CSCF receives register response, register response is transmitted to UE;
S-CSCF transmits register requirement according to the CAMEL-Subscription-Information of UE to AS;
AS returns register response to S-CSCF, such as sending " 200OK " message.
Distortion by above step 202-208 can know when ICP is on AS, do not have ICP information in the register requirement of forwarding or the Invite message.
Embodiment two
