Communication control device, communication system, computer-readable storage medium and communication control method

A non-transitory computer-readable storage medium having recorded thereon a program that causes a computer to function as:

• a communication control apparatus configured to control communication of a flying body configured to form a cell by irradiating a beam toward the ground to provide wireless communication service for a user terminal in the cell, and comprising:
• an activation unit configured to activate an offload function for causing a user terminal that exists in the cell of the flying body to be handed over to another cell in response to satisfaction of a predetermined condition;
• a determination unit configured to determine a user terminal of an offload target to be offloaded among a plurality of user terminals that exists in the cell of the flying body and a cell of an offload destination, based on a neighbor cell list of the cell of the flying body, a frequency priority list in which priorities are each associated with each of a plurality of frequencies, a radio resource usage rate of each of the plurality of user terminals, and an MCS of each of the plurality of user terminals, when the offload function is being activated;
• and
• a control unit configured to hand over the user terminal of the offload target to the cell of the offload destination.

A communication control method that is executed by a communication control apparatus configured to control communication of a flying body configured to form a cell by irradiating a beam toward the ground to provide wireless communication service for a user terminal in the cell, the communication control method comprising:

• activating an offload function for causing a user terminal that exists in the cell of the flying body to be handed over to another cell in response to satisfaction of a predetermined condition;
• determining a user terminal of an offload target to be offloaded among a plurality of user terminals that exists in the cell of the flying body and a cell of an offload destination, based on a neighbor cell list of the cell of the flying body, a frequency priority list in which priorities are each associated with each of a plurality of frequencies, a radio resource usage rate of each of the plurality of user terminals, and an MCS of each of the plurality of user terminals;
• and
• handing over the user terminal of the offload target to the cell of the offload destination.
