为实现集群通信系统广域间漫游联网的目的,该文提出了适用于集群通信系统漫游联网的网络拓扑结构,并讨论了两种漫游数据管理的方式,即分布式管理方式和集中式管理方式。在漫游数据分布式管理的方式下,分析了用户漫游和用户漫游返回的数据传输策略。
In order to achieve the purpose of inter-area roaming networking in trunking communication system, this paper proposes a network topology suitable for roaming networking in trunking communication systems and discusses two ways of managing roaming data, that is, distributed management and centralized management . In the way of distributed management of roaming data, the strategy of data transmission for user roaming and user roaming is analyzed.
