摘　　要：介绍一种既支持GSM-R又支持LTE-R通信的双模车载电台的技术方法。分析双模车载电台的基本原理、拨号机制,并重点分析其中关键的PPP协议和实际应用。按照该方法构造的双模车载电台实现了同一设备支持GSM-R与LTE-R通信,可以替代目前单一制式的高铁列车车载电台。无论是在单一的GSM-R通信网络或LTE-R通信网络或这两种通信网络混合构成的高铁线路上,本双模车载电台都能满足车载设备的通信需求。This paper introduces a technical research method of dual-mode onboard radio which supports both GSM-R and LTE-R communication.This paper analyzes basic principle and dialing mechanism of dual-mode onboard radio,and focuses on key PPP protocol and practical application,dual-mode on-board radio which constructed according to the method introduced in this paper realizes the same equipment supporting GSM-R and lte-r communication,which can replace current single system of high-speed railway on-board radio.No matter in a single GSM-R communication network or LTE-R communication network or a high-speed railway line composed of two communication networks,the dual-mode onboard radio can meet communication requirements of onboard equipment.
