Research on IMS Packet Service Triggering Algorithm Based on Double Filtering Criterion

The Service trigger algorithm is the core of the entire IMS system platform, which can affect the work efficiency and service quality of the entire system. In the early days, the service trigger algorithm officially defined by 3GPP can no longer meet the overall requirements of current big data and big user information services. In order to meet the Service needs of the multimedia network platform and the huge user group in the future, this paper conducts an in-depth study on the official Service trigger algorithm, and proposes an IMS packet Service trigger algorithm based on the double filter criteria. This algorithm achieves the goal of quickly processing multiple services by combining the packet Service trigger mechanism with the iFC+sFC dual service filter criteria. The simulation results show that the new service triggering algorithm can effectively reduce the overall session setup delay, improve the system throughput, and greatly improve the IMS system service triggering efficiency.
