Control apparatus, communication system, control method and program

A control apparatus in a wireless communication system including the control apparatus and a plurality of base stations including a movable first base station and a movable second base station, the control apparatus comprising:

• a processor;
• and
• a memory that includes instructions, which when executed, cause the processor to execute a method, the method including:
• acquiring position information of one or more specific priority terminals and shield sensing information;
• generating a shield map based on the shield sensing information;
• determining whether or not there is a line-of-sight state based on the position information and the shield map;
• and
• controlling a position of the first base station and a position of the second base station such that a number of the one or more specific priority terminals in the line-of-sight state from both the first base station and the second base station becomes a maximum wherein the number is at least 1,
• wherein the line-of-sight state is a state in which the one or more specific priority terminals are connectable to at least one of the base stations.
