Abstract: A control device is connected to a facility appliance regulating the environment of an area and to an activity measuring instrument for each activity kind measuring the status of an activity of a person in the area. The control device has: an activity kind determination part determining an activity kind corresponding to a work performed in the area; an activity information acquisition part using the activity measuring instrument corresponding to the determined activity kind to acquire the status of the activity of the person in the area; and an environment control part causing the facility appliance to control the environment of the area on the basis of the acquired status of the activity.

Abstract: In a communication system which can be connected to two different radio communication networks, wireless link quality information on a base station around both of terminals performing communication by using one radio communication network and according to the wireless link quality information, it is judged whether a radio terminal is to be connected to the radio communication network.

Abstract: In order to settle a problem of suppressing degradation of a throughput of a communication system, a communication device is provided with a reception means which receives and accumulates a first datum which a first device transmits addressing a second device and a second datum which the second device transmits, a transmission means which transmits the first datum to the second device, a quality index acquisition means which acquires a first index which is a quality of communication between the first device and the second device and a second index which is a quality of communication between the communication device and the second device, and a judgment means which forces to transmit the accumulated first datum to the second device using the transmission means in the case of judging that the second index is better than the first index and a reception condition of the second datum shows that the second device does not receive normally the first datum.

Abstract: A great delay in communication and deterioration in quality are avoided from occurring.

Abstract: Wireless LAN base station devices (107 to 109) monitored by a wireless LAN base station monitoring server device (105) send wireless LAN base station information on themselves to the wireless LAN base station monitoring server device (105). A combined wireless terminal (110) which is to start communication requests the wireless LAN base station information on connectable wireless LAN base station devices. The wireless LAN base station monitoring server device (105) sends information on whether or not there is any connectable base station device and, if any, the connectable wireless LAN base station information according to information acquired from the combined wireless terminal (110) having requested the wireless LAN base station information via a 3G network (102). The combined wireless terminal (110) having received the wireless LAN base station information determines whether or not to set up a connection to a wireless LAN network (103) from the wireless LAN base station information.
