基于TD网络实现PoC业务中CPC的研究

PoC是基于蜂窝网络的一键通业务,具有严格的时延要求.TD网络中CPC技术的引入使得处于分组域通信的用户能以更短的时延、更小的控制信道开销迅速建立连接.主要针对CPC采用的半持续性调度技术进行研究和方案设计,仿真结果表明采用CPC技术,可以提高VoIP系统容量,对PoC业务的开展提供了可靠的技术支持.

Research of CPC for the Implementation of PoC Based on TD Network

PoC is the PTT service based on the cellular network with the strict delay requirements. The users of packet switched can communicate with a shorter delay and a smaller overhead of the control channel to establish a connection quickly by introducing CPC technonogy in TD network. In this paper, the semi-persistent scheduling technology adopted by CPC is studied and a program is designed, the simulation results show that the CPC technology can improve the capacity of VoIP system, and provide a reliable technical support for the PoC service carried out.
