Circuit, base station, method, and recording medium

A circuit, comprising:

• circuitry in a base station, the circuitry configured to:
• receive action-allowable information from a moving object, wherein
• the action-allowable information includes residual battery information associated with the moving object, and
• the residual battery information indicates a residual battery amount;
• determine one of a continuous flight mode or an emergency landing mode based on the residual battery amount, wherein
• the determination of the continuous flight mode is based on the residual battery amount that is greater than or equal to a first threshold, and
• the determination of the emergency landing mode is based on the residual battery amount that is less than the first threshold;
• transmit an action instruction to the moving object based on the received action-allowable information, wherein the transmitted action instruction is associated with the one of the determined continuous flight mode or the determined emergency landing mode;
• generate a map based on the determined emergency landing mode;
• determine a danger level for a first area in the generated map;
• determine a danger level for a second area in the generated map, wherein
• the danger level of the first area is lower than the danger level of the second area, and
• the first area indicates a landing place at which the moving object is recoverable;
• notify the generated map to the moving object;
• collect first information from a plurality of nearby moving objects, wherein the moving object lands based on the collected first information;
• update the map based on the collected first information to land the moving object, wherein the first area is updated in the updated map;
• and
• transmit the updated map to the moving object.
