摘要
为了使不同地域相互独立的集群系统互通,应用TCP/IP网络技术,PCM交换技术,设计了基于宽带传输网络的集中控制方式的联网中心。应用此联网中心通过级联的方式实现集群系统的多级联网,使联网系统内用户能够自动漫游、跨系统单呼、组呼。同时设计了基于UDP协议的不同厂家集群系统接入的网关接口。
For communication between isolated trunking systems in different zones, we, based on E1 transmission network, designed the Interconnected Center System which belonged to centralized control using TCP/IP technology and PCM switch technology. The Mutilayer Roaming and Interconnected Trunking System was realized through the method of SPICE based on the Interconnected Center System. The mobiles in all the Trunking Systems could be automatic roaming, individual call and group call. To connect with the other different Trunking System, we also designed the netgate based on the UDP protocol.
