High-Speed Railway Private Network Solutions Research And Application Of GSM

From 2006 to 2010, China plans a total investment of 1.25 trillion yuan rail, nearly 80% for high-speed railway construction, the construction of a new line of 19,800 km, of which 300 km per hour on more than 5457 km high-speed rail. New high-speed railway and speed railway, light rail, will facilitate passenger travel, and promote economic development along the railway,alleviate the traffic pressure road network. But the train speed, mobile phone users within the train move the process Due to high-speed mobile Doppler effect in the course of the train material on the wireless signal attenuation and no main coverage area, such as the impact of various factors, often prone to handover confusion, unable to connect, abnormal dropped calls and other abnormal phenomena,seriously affect the mobile communication network of quality indicators and the user's talk sense.Therefore it is necessary careful study for upgrading mobile communication network quality of high-rail environment,and propose the corresponding solutionsIn this paper, to improve high-speed trains network quality of mobile communications for the purpose, against the high-speed trains good sealing, high speed, etc., completed the high-speed railway influence of the current network quality, GSM communications features of high-speed scenarios and high-speed rail scenarios GSM upgrade the quality of the analysis and discussion strategies and form related conclusions. On this basis, high-speed rail network scenarios GSM private network design principles and solutions were studied, including the private network coverage, capacity, frequency, location area, cell parameters, private network and external network Convergence and other content, foemed a the whole set of GSM private network solution system expertise, and expertise Application for the implementation in the Guangzhou-Shenzhen railway private network covers construction, the effect is clear. from the coverage, frequency, handover diversified Fully enhance the high-speed rail users voice quality, improving the user's talk senseWith private network coverage, dual-network security as the main idea of the high-speed rail GSM private network solution, will have the conditions cell of Current network to private network, realize the promotion-by-cell form private network coverage structure, and ultimately expertise a full range private network, provided useful ideas for improve the quality of high-speed rail, high-speed rail in the future an increasing number of cases, high-speed railway private network scheme will undoubtedly become the development trend of network. Application and promotion of the industry have a good reference value, with guidance, practical and effective.
