The Research and Simulation Realization of PoC Service Based on TD-SCDMA Network

In view of the development of the Push to talk over Cellular (PoC), this paper proposes two different network schemes, and every network unit function is introduced. Then the communication performance is simulated about the two schemes. Lastly, the communications of the PoC service based on TD-SCDMA network is simulated by computer. By simulation we know it is able to realize the PoC service based on TD-SCDMA network and the correlative communications parameters are analyzed. So, the existing problem of PoC service based on TD network is discussed, and the idea of the development in the next step is proposed.
