A control device includes: 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, and perform switching control for switching a state of the mobile terminal from the first state to the second state when the congestion information satisfies a given condition.

Control device, control method, and communication system

A traffic measuring apparatus provided in an exchange measures traffic caused by call control for a plurality of terminals accommodated in the exchange. The traffic measuring apparatus includes a traffic measuring section for measuring traffic in accordance with a predetermined measuring method, a load measuring section for measuring a call control load, and a measuring method change control section for changing the measuring method used in the traffic measuring section to a different measuring method in accordance with the call control load measured by the load measuring section. Accordingly, it becomes possible to perform detailed traffic measurement, while minimizing the load acting on the call control.
