Design and Simulation of Trunking Communication System in TD-SCDMA Network Based on SIP Protocol

In view of the fact that trunking communication system needs urgently to be developed toward digital system in China, a design scheme of trunking communication system based on TD-SCDMA network is given. The system is realized by adding the trunking server and improving the trunking terminal. At the same time, SIP is used as the control signaling in the system. The delay performance of this system is analyzed in detail and verified by using OPNET to establish simulation model. Finally, the result shows the scheme is reasonable and feasible.
