Abstract：The static service triggering mode of shipped IMS system made S-CSCF match triggering criteria blindly and mechanically ,and made signaling be forwarded frequently between S-CSCF and AS .As the core of IMS ,S-CSCF was not only in charge of processing the registration ,maintaining session state ,storing service configuration ,but also had to judge the routing path .Thus too much unnecessary signaling heavily strengthened the burden of S-CSCF as frequently routing back and forth ,prolonging the time of creating session .In this paper ,a better promotion named NSTA was put forward combi-ning the shipped realities .Morever ,an simulation analysis was made for comparing the old and the new triggering mechanism with queuing theory ,which demonstrated that NSTA can share the pressure of S-CSCF effectively ,reduce the signaling re-dundancy ,and well optimize service triggering performance .
