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

摘要

In the present invention, in managing a satellite communication system having a plurality of operator terminals, the plurality of operators in the satellite communication system that can maintain the data correspondence between the operator terminal with respect to the update (update) made through each operator terminal. The present invention relates to a method of maintaining data consistency between terminals, and in a satellite communication system in which a plurality of operator terminals are connected and operated, command information registered in a memory as a system change command using a command input through an arbitrary operator terminal. And a flag level of the state storage unit if it is determined to be the same command as the UPD command registered in the UPD command selection step. Status flag setting step to set as level, input command is executed. In the command execution step of executing the corresponding command by transmitting to the earth station that is the target of the row, the status flag level checking step of confirming whether the level of the status flag set in the status flag setting step after the command execution is the first level, and in this status flag level checking step The system information update step of downloading the changed system information to all the operator terminal when the level check result is determined as the first level, and resets the flag level set in the status flag setting step after the system information update execution. And a flag reset step.
