摘　　要：为满足城市轨道交通对数据业务、视频业务等高速率业务的需求,设计了基于Tetra和LTE相融合的车载终端,集成了Tetra和LTE通信所需的硬件模块,实现了指挥调度、高速数据传输、语音通话、高清视频回传、短信、彩信、多业务并发等功能,并搭建试验平台,验证达到预期效果。To meet the demand of high-speed services, e. g. data service and video service, in ur- ban rail transit, an on-board terminal is designed based on the combination of Tetra and LTE which integrates all required hardware modules of Tetra and LTE communication. This terminal can realize multiple functions, including command and dispatch, high-speed data transmission, voice call, high-definition video feed-back, SMS, MMS, Multi-service concurrency and so on. In addition, a test platform is set up to verify whether the desired results can he gained.
