摘　　要：目前基于专网的语音集群通信越来越受到覆盖范围、终端供给和网络速度等因素的制约,如何在现有的公众移动网络中,快速部署PTT(Push To Talk)集群通信服务成为通信领域的一个重要课题。并对如何在CDMA EV-DO网络中,部署基于Qchat的PTT集群通信业务进行了初步的探讨。Nowadays the private trunking communication is greatly restricted by wireless coverage, cellphone supply and network speed. How to deploy a PTT trunking communication system in the public mobile network based on the Qchat technology is the main question. This paper discussed how to deploy PTT trunking communication sevice based on Qchat in CDMA EV-DO network.
