Method for realizing railway special ratio dispatching on basis of public GSM (Global System for Mobile Communications) network

The invention relates to a method for realizing railway special ratio dispatching on the basis of a public GSM (Global System for Mobile Communications) network. According to the method, the GSM network and a hardware system comprising a locomotive station, train stations and a dispatching station are combined to realize ratio train dispatching communication, wherein the train stations and the dispatching station are respectively connected with a router; the data transmission between the train stations and the dispatching station as well as among the train stations is carried out through the internet; and the speech communication among the locomotive station, the train stations and the dispatching station is carried out through the GSM network. According to the method, the railway special ratio dispatching is realized through the public GSM network platform, and ratio train dispatching communication can be realized in places without a GSM-R (Global System for Mobile Communications for Railway) network, so tha
