一种集成用户识别模块的GSM-R通信模块
摘要：
本发明公开了属于铁路通信设备领域的一种集成用户识别模块的GSM-R通信模块。该模块将现有的GSM-R通信模块和集成用户识别模块进行硬件集成，并引入OTA技术对集成用户识别模块中的信息进行修改。本发明从根本上避免了由于振动、气温变化等原因导致现有SIM卡与GSM-R通信模块接触不良，以致通信中断或数据传输错误的事件发生，同时也方便了维护人员的管理和维护。
摘要（英）：

The invention discloses a GSM-R communication module for an integrated user identity module, which belongs to the field of railway communication devices. The module integrates hardware of an existing GSM-R communication module and the integrated user identity module and introduces an OTA technique to modify the information in the integrated user identity module. By adopting the GSM-R communication module, bad contact between an existing SIM card and the GAM-R communication module which results in the occurrence of communication interruption or a data transmission error due to vibration, temperature change and the like can be fundamentally avoided, and simultaneously, the management and maintenance are convenient for maintainers.
