Control method, control device, and communication system

A control device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• acquire information indicating a predicted position of a mobile terminal that requests data that is able to be received from a first communication device,
• identify, based on the acquired information, a second communication device that is able to communicate with the mobile terminal located at the predicted position,
• cause the second communication device to start receiving the data from the first communication device before the identified second communication device becomes able to communicate with the mobile terminal, and
• cause the second communication device to transmit the received data to the mobile terminal after the second communication device becomes able to communicate with the mobile terminal.

A communication system comprising:

• a mobile terminal configured to request data that is able to be received from a first communication device;
• a second communication device configured to communicate with the mobile terminal located at a predicted position;
• and
• a control device configured to:
• identify the second communication device based on information indicating the predicted position of the mobile terminal,
• cause the second communication device to start receiving the data from the first communication device before the identified second communication device becomes able to communicate with the mobile terminal, and
• cause the second communication device to transmit the received data to the mobile terminal after the second communication device becomes able to communicate with the mobile terminal.
