- Method for dual controlling using front and rear TRIU based on LTE-R

摘要

The present invention relates to an LTE-R based duplication control method and system. This duplication control method based on the LTE-R is a process of connecting a first and second mobile station apparatuses, which are installed in front of and behind a train respectively, in communication so as to perform communication using the first mobile station apparatus The control unit controls so that the performance of the call is maintained using the second-phase mobile station when a communication failure that can not be performed in the first mobile station is detected in the first mobile station. According to the present invention, It is possible to provide a continuous service by using another apparatus even if a failure occurs in one apparatus.
