摘 要 PAGE PAGE I 城市轨道交通通信系统的设计（LTE—M） PAGE II PAGE II 摘 要 在社会高速发展的今天，经济迅猛进步，轨道交通已经变成了现代城市中极其重要的交通工具。而城市轨道交通的运营必定离不开大量的信息处理和交互，为城市轨道交通设计一个高效，可靠的通信系统，是对社会和城市发展的迫切要求，是城市轨道交通中至关重要的一部分。 为了让城市轨道交通系统更好安全、稳定的运行，为城市的广大市民提供方便和便利，设计一套智能化，能够充分发挥城市高效能的优势。对于轨道交通系统中，智能的网络工程建设起着非常重要的作用。其中通信系统是在当中完成着各种信息的传输，在整个的轨道系统中发挥着中枢神经的系统作用。 本文主要介绍LTE-M技术的基础上，重点研究和论述基于LTE-M的B-TrunC即宽带多媒体数字集群网络的规划和设计。是要从高速数字传输网以及此方面业务的未来发展方向出发，从新一代的LTE-M宽带多媒体数字集群技术来打破传统的SDH、WDM在分组业务传输上的局限性。 是根据LTE-M宽带多媒体集群技术中的关键技术原理结合实际的需求设计接入网的方案。而一套可靠智能的交通通信系统，可以使轨道交通在现代城市中发挥巨大的作用。 关键词：城市轨道交通，通信系统，LTE-M ABSTRACT ABSTRACT In the rapid development of society today, the rapid economic progress, rail transit has become a modern city is extremely important means of transport. And the operation of urban rail transit is inseparable from a lot of information processing and interaction, for the urban rail transit design of an efficient and reliable communication system is an urgent requirement for social and urban development, urban rail transit is a vital part. In order to make the urban rail transit system better safe and stable operation, for the general public to provide convenience and convenience, the design of a set of intelligent, can give full play to the advantages of high-performance cities. For the rail transit system, intelligent network construction plays a very important role. Where the communication system is in which the completion of a variety of information transmission, in the entire orbit system to play the role of the central nervous system. Based on LTE-M technology, this paper focuses on the planning and design of B-TrunC, a broadband-based multimedia digital trunking network based on LTE-M. Is from the high-speed digital transmission network and the future direction of business in this direction, from a new generation of LTE-M broadband multimedia digit
