Control device, control method, and communication system
First Claim
1. A control device comprising:
- a memory; and
a processor coupled to the memory and configured to;
acquire congestion information indicating a congestion state of communication of wireless local area networks (LANs) which are connection destination candidates of a mobile terminal configured to switch a state thereof between a first state and a second state, in the first state the mobile terminal being wirelessly connected to a radio base station of a mobile communication network and not performing a detection operation of a wireless LAN among the wireless LANs, and in the second state the mobile terminal performing the detection operation and being wirelessly connected to a detected wireless LAN,determine when the acquired congestion information satisfies a given condition;
acquire movement speed information indicating a movement speed of the mobile terminal; and
perform switching control for switching a state of the mobile terminal from the first state to the second state when both the congestion information is determined to satisfy the given condition and the movement speed of the mobile terminal is less than a given movement speed, by transmitting a control signal, to trigger the switching, via the base station to the mobile terminal.

10. A control method comprising:
-
acquiring congestion information indicating a congestion state of communication of wireless local area networks (LANs) which are connection destination candidates of a mobile terminal configured to switch a state thereof between a first state and a second state, in the first state the mobile terminal being wirelessly connected to a radio base station of a mobile communication network and not performing a detection operation of a wireless LAN among the wireless LANs, and in the second state the mobile terminal performing the detection operation and being wirelessly connected to a detected wireless LAN; determining when the acquired congestion information satisfies a given condition; acquiring movement speed information indicating a movement speed of the mobile terminal; and performing, by a processor, switching control for switching a state of the mobile terminal from the first state to the second state when both the congestion information is determined to satisfy the given condition and the movement speed of the mobile terminal is less than a given movement speed, by transmitting a control signal, to trigger the switching, via the base station to the mobile terminal.

11. A communication system comprising:
-
a mobile terminal configured to switch a state thereof between a first state and a second state, in the first state the mobile terminal being wirelessly connected to a radio base station of a mobile communication network and not performing a detection operation of a wireless local area network (LAN) among wireless LANs, and in the second state the mobile terminal performing the detection operation and being wirelessly connected to a detected wireless LAN; and a control device configured to; acquire congestion information indicating a congestion state of communication of the wireless LANs which are connection destination candidates of the mobile terminal, determine when the acquired congestion information satisfies a given condition, acquire movement speed information indicating a movement speed of the mobile terminal; and perform switching control for switching a state of the mobile terminal from the first state to the second state when both the congestion information is determined to satisfy the given condition and the movement speed of the mobile terminal is less than a given movement speed, by transmitting a control signal, to trigger the switching, via the base station to the mobile terminal.
