1. A communication control apparatus comprising:
a first paging control unit that causes one base station of a terrestrial base station and a non-terrestrial base station to transmit a first paging signal to a communication device in a location registration area that includes at least one terrestrial communication cell provided on the ground by the terrestrial base station installed on the ground and at least one non-terrestrial communication cell provided on the ground by the flying non-terrestrial base station;
a second paging control unit that causes other base station of the terrestrial base station and the non-terrestrial base station to transmit a second paging signal to the communication device, when there is no response from the communication device to the first paging signal;
a base station estimation unit that estimates a base station to which the communication device is connected, wherein
the first paging control unit causes the base station estimated by the base station estimation unit to transmit the first paging signal; and
an overlapping area identification unit that identifies an overlapping area of the terrestrial communication cell and the non-terrestrial communication cell, wherein
the base station estimation unit estimates the base station to which the communication device at least in the overlapping area is connected.
