摘要：數(shù)字集群通信具有按鍵即講、接續(xù)速度快等業(yè)務特點，其結合通信體制上高效靈活的無線信道共享方式，在專網(wǎng)領域得到廣泛應用。本文從數(shù)字集群通信應急應用場景出發(fā)，提出一種窄帶數(shù)字集群系統(tǒng)與天通一號衛(wèi)星移動通信系統(tǒng)的融合通信應用方法，通過衛(wèi)星的廣域覆蓋能力，解決大跨度下集群覆蓋不足的通信問題。

關鍵詞：數(shù)字集群系統(tǒng)；天通一號衛(wèi)星移動通信系統(tǒng)；應急通信；融合通信

Abstract： Digital cluster communication has business characteristics such as button to talk and fast connection speed. Combined with the efficient and flexible wireless channel sharing method in the communication system， it has been widely used in the field of private networks. Starting from the emergency application scenario of digital cluster communication， this article proposes a fusion communication application method of narrowband digital cluster system and Tiantong-1 satellite mobile communication system， which solves the communication problem of insufficient cluster coverage under large spans through the wide area coverage capability of satellites.

Keywords： digital cluster system; Tiantong-1 satellite mobile communication system; emergency communication; fusion communication

數(shù)字集群通信從模擬對講發(fā)展而來，逐漸演化出DMR、TETRA、PDT等窄帶通信體制和B-TrunC寬帶集群體制等，在警用、應急、鐵路和軌道交通等行業(yè)用戶中有著廣泛的應用。（剩余3340字）
