| Abstract: | To reduce the potential signaling traffic in IP multimedia subsystem(IMS),the session establish- ment procedures were investigated.The serving call session control function(S-CSCF)is the major bot- tleneck in IMS and the existing 3GPP service triggering algorithm(STA)based on initial filter criteria (iFC)increases the end-to-end session setup delay remarkably.To reduce the session setup delay and improve the system performance,a SIP response message based filter criteria(rFC)was proposed.Based on the rFC,a ... |
