1. A mobile relay station mounted in a vehicle, comprising:
an antenna system configured to transmit and receive a radio wave inside and outside the vehicle; and
a wireless control station configured to control directivity of the antenna system, and switch between a first relay mode and a second relay mode,
the first relay mode being a relay mode for wireless communication between a wireless communication apparatus outside the vehicle and a different wireless communication apparatus inside the vehicle,
the second relay mode being a relay mode for wireless communication between a wireless communication apparatus outside the vehicle and another wireless communication apparatus outside the vehicle,
wherein the wireless control station is configured to (i) turn on the first relay mode and turn off the second relay mode or (ii) turn off the first relay mode and turn on the second relay mode on the basis of predetermined control information,
wherein the control information includes a switch instruction generated in response to charging of the vehicle, and
wherein the wireless control station is configured to turn off the first relay mode and turn on the second relay mode in a case where the switch instruction is input.
