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.
