Railway private network communication guarantee method and system

Abstract

The embodiment of the invention provides a railway private network communication guarantee method and system. The method comprises the steps of sending a network state query instruction to a GSM-R module at each preset time interval, obtaining query response information of the GSM-R module, and if it is judged that the response information meets a preset condition, modifying registration flag bitinformation into a logout state and executing a logout process; after the logout process is finished, modifying the registration flag bit information to be in a reset state, executing an initialization processing process after reset operation is executed, and initiating network registration again, wherein the preset condition is specifically that the number of times of not receiving the response of the GSM-R module reaches the preset number of times. According to the railway private network communication guarantee method and system provided by the embodiment of the invention, when the communication state between the train tail locomotive station and the train tail host is lost, the communication equipment is reset and network registration is carried out, so that the smoothness of the traintail locomotive station and the train tail host is guaranteed, and the GSM-R data communication success rate in the railway private network is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication guarantee method and system for a railway private network. Background technique [0002] GSM-R (Global System for Mobile Communications–Railway) is an international wireless communication standard for railway communication and applications. Subsystems of the European Railway Traffic Management System use GSM-R to complete the communication between trains and dispatch centers. The system is based on GSM and EIRENE–MORANE (European Railway Enhanced Integrated Network for Radio Communications) without any loss of communication at speeds up to 500 km / h. [0003] With the development of information technology, digital mobile communication system has become the mainstream of mobile communication, and GSM-R communication mode has been widely used in railway train end equipment. If the communication efficiency of the GSM-R module is not high, the communica...

Problems solved by technology

[0005] In order to solve the problem in the prior art, it is relatively passive to realize GSM-R network communication and obtain communication data only by judging the status of the module. Once there is a problem in the GSM-R module network, when the communication between the locomotive station and the train end host fails, the problem cannot be detected in time , the embodiment of the present invention provides a railway private network communication guarantee method and system
