摘　　要：基于公众蜂窝移动通信网络的PTT业务称为PoC业务。由于PoC业务呼叫建立时间短,能够发起半双工方式的群组呼叫,并且基于3G网络的IMS架构,从而成为未来3G网络中备受瞩目的移动通信业务。本文主要介绍了PoC业务标准发展情况,并结合IMS网络结构对PoC业务发展趋势进行了分析。PoC is based on cellular mobile network. Because of immediate communication with one or more users, half-duplex group session and based on 3G IMS platform, PoC becomes a much more popular service in the future 3G network. This paper mainly introduces the state of PoC standards, and analyses the direction of PoC service development with the IMS framework.
