摘要
A method for matching initial request messages in the IP multimedia subsystem service triggering process comprises: before the S-CSCF forwards an initial request message to the AS, generating a trigger request identifier uniquely and inserting the identifier into the initial request message; then forwarding the initial request message to the AS; and then the AS copies the trigger request identifier in the received message into the initial request message to be sent back; finally, the S-CSCF determines whether a received initial request message is the response to the initial request message sent to the AS by the S-CSCF previously based on the trigger request identifier, determines the corresponding relationship, and then performs the subsequent service control process. With the present invention, the requirement that the S-CSCF must correctly match the initial request message with the one sent back can be satisfied, thus guarantee the normal performance of service triggering.
