GSM-R网络服务质量监测系统设计

GSM-R移动通信网的高速发展,特别是铁路运营中的列车调度通信、列车控制系统、高速列车通信网络的改进,对GSM-R移动通信网的测试监测提出了新的要求,因此,开发一套对整个通信网络进行网元级和系统级的综合评估监测系统势在必行。主要介绍网络服务质量监测系统的功能、结构、特性及涉及的部分关键技术,并对其发展前景作出了展望。

With the rapid development of GSM-R mobile communication networks, the quality of service （QoS） for GSM-R mobile communication network has to be improved to meet with the requirement of train dispatching communication, train controlling system and high-speed train communication network for railway operation. It is necessary to set up a monitoring system so that the comprehensive evaluation for cell and system can be realized for the communication net- work. This paper focuses on the function, structure, characteristic and key problem of network QoS monitoring system and puts forward its prospects.
