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

A non-transitory computer-readable storage medium comprising a program stored thereon, the program causing a computer to function as:

• a relative-speed acquiring unit for acquiring relative speeds of a movable first mobile relaying apparatus and a movable second mobile relaying apparatus, which are camped on a cell of a wireless base station to relay communications between the wireless base station and a wireless communication terminal;
• and
• a determination unit for determining, based on the relative speeds, whether the second mobile relaying apparatus becomes a handover destination, from the first mobile relaying apparatus, of the wireless communication terminal camped on the first mobile relaying apparatus, or becomes a carrier-aggregation destination of the first mobile relaying apparatus for the wireless communication terminal camped on the first mobile relaying apparatus, wherein the determination unit determines the second mobile relaying apparatus as the handover destination or the carrier-aggregation destination, when the relative speeds are slower than a predetermined threshold.

A control method performed by a computer, the control method comprising:

• acquiring relative speeds of a movable first mobile relaying apparatus and a movable second mobile relaying apparatus, which are camped on a cell of a wireless base station to relay communications between the wireless base station and a wireless communication terminal;
• and
• determining, based on the relative speeds, whether the second mobile relaying apparatus becomes a handover destination, from the first mobile relaying apparatus, of the wireless communication terminal camped on the first mobile relaying apparatus, or becomes a carrier-aggregation destination of the first mobile relaying apparatus for the wireless communication terminal camped on the first mobile relaying apparatus, wherein the determining includes determining the second mobile relaying apparatus as the handover destination or the carrier-aggregation destination, when the relative speeds are slower than a predetermined threshold.
