An equipment control system includes a disaster notification apparatus configured to transmit a disaster notification, and a wireless communication apparatus provided in a building. The wireless communication apparatus receives the disaster notification, and determines whether a user of a portable terminal is present in the building, based on a communication situation between the wireless communication apparatus and one or more portable terminals. Upon receiving the disaster notification, the wireless communication apparatus controls one or more pieces of equipment installed within the building, differently depending on whether the user of the portable terminal is present in the building.

System and method for controlling equipment installed within a building upon receiving disaster notification

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.
