%X To determine the potential signaling traffic reductions, the session establishment procedures in IMS (IP Multimedia Subsystem) are investigated. The investigation showes that, the S-CSCF (Serving Call Session Control Function) is the major bottleneck in IMS network. To reduce the session setup delay and improve the system performance, a new Group based Service Triggering Algorithm (GSTA) is proposed. And then the modeling of 3GPP (3rd Generation Partnership Project) Service Triggering Algorithm (3GPP STA) and GSTA are presented. Theoretical analysis and simulation results show that, GSTA efficiently reduces the signaling traffic load at the S-CSCF, increases the throughput of the system and significantly reduces the session setup delay, improves IMS network quality of service.
