The trunking communication system is a shared resource, cost-sharing, sharing of equipment and services channel multi-purpose, high performance wireless dispatch communication system.So it is not adapt to assemble communication now.Using Trunking system has been put forward more and more pressing needs for domestic communications industry. This paper research application of trunk communication system based on smartrunk protocol,introduces the capability,installation setup,programming, operation.and trends of SmarTrunk communication system and so on. Using ST-853 controller, repeater, wireless terminals, antenna systems and system software components SmarTrunk communication system, and then ST-853 controller and the system parameters may be used can be programmed . The system can provide to users and managers a great convenience, capacity can be easily extended,Especially the secondary generation protocol-SmarTrunk Ⅱis more capable,more quick and safe,It provides an advanced method and means for integration of channel,and that put forword an effective resolvent for consummate the communications function in middling and small city. Turn the regular communication channel into a trunking management system, not only can significantly increase system capacity and flexibility and system can provide security, system security, and other advanced functions such as selected calling, emergency calls, etc. Key words: channel; utility ratio; trunk; communication system 目录 摘要 I Abstract II 第1章 绪论 1 1.1课题的研究意义及背景 1 1.2集群通信系统发展概况 2 1.3论文内容及结构
