The management server stores state data received from the devices in a management table. The state data contains proximity information for judging the length of time until a user checks a screen and availability information associated with the availability of the battery operation. The management server selects a target device requiring a predetermined action and a notification device notifying a message associated with the predetermined action based on the state data from the plurality of devices. The management server notifies the notification device of a message associated with the predetermined action. The message can be a charging prompt or an approval for shutdown.

Abstract: A mobile terminal device is connected to a network using a packet routing function of another mobile terminal device. Communication between respective mobile terminal devices can be performed in each of a plurality of tethering connection systems. When performing tethering communication, a mobile terminal device having tethering function becomes a master device and a mobile terminal device having no tethering function becomes a slave device. When both mobile terminal devices have tethering function, one mobile terminal devices becomes the master device and the other becomes the slave device. Before starting the tethering communication, state information for calculating an expected battery operating time of each mobile terminal device is acquired. A tethering connection system and a master-slave relationship are selected to maximize the expected operating time based on the remaining battery level and the expected power consumption of each mobile terminal device when starting the tethering communication.

In a power-off state, a PWC receives electricity from the battery unit or an AC/DC adapter. In the power-off state, a system of the EC stops.

When a logic circuit detects the operation of the cover switch, the PWC controls a DC/DC converter group to activate the system. The EC receiving electricity turns the FET OFF. Then the PWC turns the FET OFF.
