Step 2, P-CSCF processes this REGISTER request, and the REGISTER request is sent to the I-CSCF of selection.
Step 3, I-CSCF then can contact HSS, sends Cx inquiry (Cx-Query) message to HSS, with the address of inquiry S-CSCF.Wherein, Cx is the call conversation control entity (Call ServerControl Function, CSCF) of agreement regulation and the interface between the ownership place subscription data server (Home Subscriber Server, HSS).
Step 4, HSS selects S-CSCF, and I-CSCF is issued by Cx inquiry response (Cx-Query Response) message in the S-CSCF address.
Step 5, after finishing the S-CSCF selection, I-CSCF is transmitted to the REGISTER request S-CSCF of selection.
Step 6, S-CSCF can find that this UE is not authorized to, and can send Cx authentication (Cx-Authentication) message to HSS, to obtain authorization data.
Step 7, HSS crosses Cx Authentication Response (Cx-AuthenticationResponse) message with the authentication data communication device and returns to S-CSCF.
Step 8, S-CSCF replys to query the user with " 401 unauthorizeds (Unauthorized) ".And message passed to I-CSCF.
Step 9, I-CSCF replys " 401 unauthorizeds (Unauthorized) " and sends to P-CSCF.
Step 10, P-CSCF replys " 401 unauthorizeds (Unauthorized) " and sends to UE.
Step 11, UE can calculate replying of this query and send one to P-CSCF and new comprise the REGISTER that this is replied.
Step 12, P-CSCF can find I-CSCF again, and new REGISTER message is sent to I-CSCF.
Step 13, I-CSCF then can contact HSS, sends Cx inquiry (Cx-Query) message to HSS, with the address of inquiry S-CSCF.
Step 14, HSS issues I-CSCF to the S-CSCF address of choosing by Cx inquiry response (Cx-QueryResponse) message.
Step 15, I-CSCF is transmitted to new REGISTER request the S-CSCF of selection.
S-CSCF can check that this replys, if incorrect, failed authentication then, register flow path stops.If correct, then authentication success.
Step 16, message that if S-CSCF checks the authentication success, then S-CSCF will Cx pushes on or Cx pops to sending from HSS (Cx-Put Cx-Pull).
Step 17, HSS preserves S-CSCF name that should the user, and returns push on response or Cx of Cx and pop response (Cx-Put Response Cx-Pull Response) message to S-CSCF.S-CSCF preserves corresponding user profile.
Step 18, S-CSCF sends " 200OK " message to I-CSCF, and this registration is accepted in expression.
Step 19, I-CSCF transmits to P-CSCF should " 200OK " message.
Step 20, P-CSCF sends " 200OK " message to UE.
Step 21, S-CSCF sends registration request (REGISTER) message to application server AS.
Step 22, application server (Application Server, AS) returns " 200OK " message to S-CSCF, and this registration is accepted in expression.
