摘要
为了评估EDGE技术在铁路场景及高速移动场景的业务承载能力及系统服务质量,采取实验室半实物仿真测试和铁路现场测试相结合的方式,对铁路EDGE系统性能进行测试分析.测试结果表明EDGE具有良好的高速适应性,在高速场景下能够满足铁路业务的服务质量需求;相比于GPRS,EDGE上行吞吐量增加了70%以上,下行吞吐量增加了90%以上,时延性能相当.
In order to evaluate the service bearing capacity and system QoS of EDGE technology in railway scenarios as well as under high-speed mobile scenarios,the performance metrics of the EDGE system for railway are measured and analyzed by combining hardware-in-the-loop simulation test and railway on-site test.The test results show that the EDGE has good adaptability to high-speed and can meet the QoS requirements of railway communication services in actual railway scenarios?Compared with GPRS,EDGE can improve the capacity substantially with the uplink throughput increased by more than 70%and the downlink throughput increased by more than 90%.
