一种话权控制方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种话权控制方法及装置。
背景技术
PoC(Push-to-Talk over Cellular，基于公共蜂窝网的一键通功能)是公众蜂窝移动通信网络中的PTT(Push-to-Talk，即按即讲)业务。PTT业务实现了手提无线电话机Walkie-Talkie的移动语音业务，具有呼叫建立时间短，讲话才占用信道，接听只监听信道，接收方无需摘机即可随时接受呼叫信息。
PoC是一种双向、即时和多方通信的方式。允许两个或者两个以上用户设备进行通信。用户按键能够将语音发送给会话的所有参与者。
在现有PoC业务方案中，话权控制的方案是采用RTCP(Real-Time Transport Control Protocol，实时传输控制协议)协议通过用户设备的专有单播连接进行话权信息上报。而在PoC架构中，控制面的信令和媒体面的承载都是在POC服务器PoC Server中实现的，并没有将控制面和媒体面分离，为之后的技术演进造成了困难，不利于业务的灵活实现，也不利于***的扩展。现有技术中也没有控制面和媒体面分离后关于话权控制的详细流程。
