摘要
铁路GPRS(通用分组无线服务技术)与公网GPRS在通信环境和业务特征、传输质量等方面具有较大差异,铁路GPRS业务通常为小数据、高频率的车-地信息,对传输质量要求较高。通过分析发送不同长度数据时GPRS空口的传输性能,为铁路GPRS优化提供参考。
There are substantial differences between railway GPRS and public GPRS in term of communication environment and the characteristics of services, etc. Typical GPRS services for railway are small high frequency data of train-ground information but high quality of data trans- mission is required. We mainly analyze the transmission performance of the air interface of GPRS when data of different length is transmitted, providing reference for the optimization of railway GPRS.
