数字集群通信系统快速呼叫接续方法研究

Research on Connection Method of Voice Call Service in Digital Trunking Communication System

按键即讲(PTT)是数字集群通信系统有别于公网移动通信系统的显著特点,需要快速呼叫接续。本文提出一种应用于数字集群通信系统的局内局间快速呼叫处理方法,通过该方法,可以降低系统的呼叫延迟,提高集群通信系统呼叫接续速度。

The key difference between digital trunking system and the traditional public telecommunications system is PTT（Push To Talk） service. And the time of connection is the most important technical parameter to the performance of PTT. This document presents a connection method of voice call service. Through this method, the MSC system can reduce the call delay and the two part of the call service can be connected rapidly.
