Research On The Application Of GSM Network In High-speed Railway Coverage

As in China economic of high speed development, people living constantly improve, traffic transport cause constantly rapid development, high speed railway design speed 300km/hours, through plain, and tunnel and road embedded, multiple terrain, while, as wireless network cover of constantly perfect and quality of upgrade, user on network cover, and quality made has increasingly high of requirements, about high speed railway cover of problem increasingly more to appears in actual GSM network construction.Traditional GSM system its by support of limit speed defined for 250 km, but due to lack application scene, causes, makes existing GSM system even 200 km of high speed are cannot effective support, therefore railway speed increase appears off words rate high, and playing does not phone, and switch failed rate high, and voice quality poor problem, system performance fell very large, in in China railway speed increase, in railway along appears many problem.In recent years, a large number of high-speed railway put into operation and the people's increasing demand for mobile communication services, GSM networks so that mobile operators are faced with greater challenges.1) which GSM network enhanced or improved application support in fast-moving scenes of normal communication is mobile operators there is an urgent need to address the problem.2) high speed railway principles, programs, covering the planning model is very important for carriers.3) high speed railway covering needs some specific strategies, rules, there is an urgent need to study.In conclusion, high speed rail cover planning study is to improve the network coverage, enhance network not only provides communication services, quality, protecting the needs of business income, also is the embodiment of the social responsibility of operators, with high social benefit.This paper is based on such of demand expand on high speed railway cover of in-depth analysis research, first research analysis high speed railway cover of status, and effect high speed railway cover of factors, then on high speed railway cover application scene more analysis, describes has high speed railway cover in the of various technology characteristics, through research analysis, full mining GSM technology potential, made a based on RRU total community of high speed railway group network planning program, contains general scene and the special scene of group network program, developed high speed railway cover of planning principles, and Methods, processes, combined with specific scenes explain the characteristic parameters in high speed railway covering planning, policy implementation, which has a role in guiding the construction of high-speed rail plan in the future.
