摘要
在LTE系统中引入了群组预建立和邻区群组信息广播机制,使得集群终端在小区之间切换/移动无需和基站之间的信令交互而成为一种无缝切换过程,避免了切换过程中的信令交互和延迟;提出一种基于随机过程的群组呼叫建立过程的方法,使得话权申请的过程不依赖于信令链接,有效地提高了系统的性能。
The group pre-establishment mechanism and neighbor group information broadcast mechanism have been added to LTE systems. In new LTE systems, handover of trunk terminals between cells does not require any signaling between base stations. Handover is seamless and without delay. In this paper, we propose group call establishment based on a random procedure. This ensures that the process of granting a call request is not based on signal connection. This solution improves system performance.
