关于GSM-R移动通信系统检测评价标准的思考

Thoughts of Check and Appraisal Standard of GSM-R

目前铁路GSM-R已经建成多条线路,GSM-R系统的检测工作应该成为保证网络运营质量的重要手段。根据以往的测试经验和对相关技术指标的理解,对铁道部正在制定的测试规范草案,现提出了一些看法。针对目前的一些GSM-R系统的检测标准和检测方法,比如:检测天线高度、检波方式、特殊呼叫检测的限制等,提出了应该完善和可实施性的建议。

GSM-R systems have been built up on quite a few railway lines. The testing of the GSM-R system should become an important mean of ensuring the quality of network operation. This paper put forward some viewpoints on the testing specification draft based on testing experience and understanding of related technical parameters. In terms of some existing testing criterion and approaches for GSM-R system, such as the height of testing antenna, way of test wave, testing limitation of special call, this paper puts forward the suggest that the draft should be perfected and carried out , for example the demodulation and the individual call confinement.
