ABSTRACT:
A method for processing SIP requests in an IMS network includes: an AS in the IMS network receiving a first SIP request forwarded by a S-CSCF entity, generating a second SIP request and deciding whether it is needed to associate the second SIP request with the first SIP request in terms of service logic at the S-CSCF entity, if it is needed to associate two requests, removing the URI of the AS from the Route header of the first SIP request; otherwise, regenerating the Route header of the second SIP request in the originating UA behavior mode and sending the second SIP request to the S-CSCF entity. Also disclosed is a system for processing SIP requests in an IMS network, including an AS and a S-CSCF entity. Also disclosed is an AS for processing SIP requests in an IMS network and a network entity for service control.
