摘要
为了在突发情况下,将需要统一通话的终端切换到一个通话组,提出一种基于DMR控制组切换的调度方法。研究DMR系统组成、切换流程,以及切换格式命令等;详细给出DMR统一调度方法在铁路客站的应用方案。
A DMR scheduling method based on control group switching is proposed,which can switch all the terminals requiring unified talk to the same talk group in the case of emergency.The composition,switching process and format change command of the DMR system are described.In the end,an application scheme of the unified DMR scheduling method in railway passenger station is expounded in detail.
