摘要
针对铁路综合移动通信网的组网存在的很多难题,根据以往的GSM组网技术难以解决铁路通信网组网存在的特有问题,概述铁路综合移动通信网的发展和组网技术,分析铁路通信网组网独特的特点和存在的特有难题,结合这些特点提出了解决办法;然后,重点阐述这些组网技术对现有铁路业务的适应性,以及其对未来发展铁路业务发展的支持性;着重分析和研究铁路通信网组网的关键技术问题与策略。
Nowadays, there exist a number of problems to be solved on railway integrated mobile communication networks, yet no satisfying solutions have been rendered by far. The previous GSM mobile communication network technologies could not find a way to solve the specific problem of railway integrated mobile communication network. This paper firstly introduces the development and technology of railway integrated mobile communication network, analyses its typical features and existing specific problems. Solutions are presented in accordance with these features; then the adaptability of the networks to the railway service at present and its supportability to the development of railway service are focused. This paper mainly emphasizes and studies the key technology problems and strategies to the solutions.
