METHOD FOR MAINTAINING DATA CONSISTENCY BETWEEN MULTIPLE OPERATOR TERMINALS IN SATELLITE COMMUNICATION SYSTEM

摘要

The present invention manages a satellite communication system having a plurality of operator terminals, the satellite communication system that can maintain the data consistency between the operator terminal with respect to the update (update) made through each operator terminal The present invention relates to a method for maintaining data consistency among multiple operator terminals in a satellite communication system in which a plurality of operator terminals are connected and operated, by comparing a command inputted through an arbitrary operator terminal with a previously registered system change command. UPD instruction screening step for determining whether it is a system change command based on the identity or not, and if it is determined to be the same command as the UPD command registered in the UPD command screening step, the current time counted by the timer is recorded in the memory. Update time recording stage, the earth to execute the input command An operator terminal index for indexing an operator terminal that has been updated at an earlier time point by comparing the time data recorded in the command execution step of executing the command and executing the command and the update time recording step after the command execution with the update time of another operator terminal. And an update step of updating and storing the system information and the update time information of the indexed operator terminal as its own data.
