提出了一个在基于TD-SCDMA的数字集群通信中实现短消息业务的网络体系结构设计方案,介绍了该结构各实体的功能。针对在该结构下短消息业务的实现,设计了对应的信令流程,并按照集群的特性提出了一些特殊的业务实现方案。
Proposed a network architecture design scheme for implementing short message service in digital trunking communication based on TD-SCDMA, and introduced the functions of each entity of the structure. Aimed at the realization of short message service in this structure, the corresponding signaling flow is designed and some special business solutions are proposed according to the characteristics of the cluster.
