摘要
集群调度通信是GSM-R系统的重要业务,因相关协议规范存在空白点,业务实现可能存在不确定因素.本文对集群调度通信所涉及的呼叫建立、保持、释放和资源动态管理过程进行研究,综合考虑通信参与者、对象、角色,随网络位置、网络环境变化的特性,深入分析了影响集群调度通信性能的各种潜在因素,明确了动态和静态因素对互联互通的影响程度和范围,并提出了解决建议.
Although digital trunking dispatch service is very important for GSM-R; it still has some problems in specification which spare description may not be ignored. This paper deeply analyses the mechanism of trunking dispatch service about call setup, constrain, release and resource dynamic management. The research shown that the performance was influenced by different factors： communication users, objects, roles, network location or environment in the network. Some potential influences on interoperability testing were deeply discussed. Finally, service flow control scheme and optimization solution have been proposed for trunking mobile communication network.
