摘要
TDMA星状网是为了适应中心站与大量低速站点之间的通信需求而开发的一种通信体制。本文介绍了一种方法,可以通过中心站转发和双向业务分配,实现星状网全网业务互通,并可以根据实时或非实时类业务灵活分配信道资源,实现区别化的传输服务。本方法的关键步骤为:业务流划分与标记、双向时隙申请分配、以及业务流中心转发。由于本方法实现简单、应用灵活、并且具有一定服务保障能力,所以非常适合TDMA卫星通信系统综合业务的传输过程。
TDMA star network is a satellite communication system developed to meet the communication needs of the central station and low-speed stations.This paper introduces a method to realize the interconnection of the entire star network through the forwarding of central station and the bidirectional service assignment.This method can allocate channel resource according to real-time or non-real-time service to realize discriminating transmission service.The key steps are:service flow division and marking,bi-directional slot request allocation,and traffic center service flow forwarding.This method is simple to implement,flexible to apply,and has certain service assurance capabilities.It is suitable for TDMA satellite communication transmission process.
