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

数字集群通信从模拟对讲发展而来，逐渐演化出DMR、TETRA、PDT等窄带通信体制和B-TrunC宽带集群体制等，在警用、应急、铁路和轨道交通等行业用户中有着广泛的应用。（剩余3340字）
