Research Of GSM-R Network In China Railway

GSM-R technology is a specified application of GSM in railway communication. With increasing length of China railway in operation and increasing train speed, the existing communication technology which is called wireless train dispatching system in 450MHz can not meet the need of train whose speed is more than 300Km/h, especially in train control, data transfer and coach state monitoring, etc. GSM-R technology will meet the need of the above perfectly. So we can draw a conclusion that GSM-R will be main communication application in China high speed railway.As a specified application of GSM system in railway, GSM-R network is completely compatible with GSM standard. GSM-R expands some special function based on GSM network. In China, GSM-R network has developed for more than 6 years. With rapidly increasing investment in China railway recently, GSM-R network expends fast too. It has been main communication system in China high speed railway, even exclusive system. GSM-R’s development now is significant focus in China railway communication market.This article will tell about GSM-R history in China first. Then it will tell about China GSM-R network and network frame planning. As most important content in mobile communication network, the article will research in number planning of GSM-R deeply. Because of GSM-R’s special construction way which is being built and being operated, as the first operation employee, the author will bring out main problem in GSM-R’s structure and management. Then the author gives suggestion of such problems in particular sense.
