Wireless communication system and mobile information terminal

摘要

Disclosed is a wireless communication system capable of easily reconnecting a mobile information terminal and a base unit when a user returns home and letting the user know missed incoming call information or the like. To this end, when being unable to receive a signal from the base unit, the mobile information terminal enters into a sleep state, and when a predetermined operation is performed, the mobile information terminal searches for the base unit, and when reconnecting to the base unit, the terminal displays information on an item transmitted from the base unit on an operation display section. Thus, even when the user returns home but forgets switching an operation mode, the mobile information terminal searches for the base unit as soon as the predetermined operation is performed, and can obtain necessary information from the base unit at home by a simple operation when the user desires the information.

主权项

1. A wireless communication system comprising:
a base station connectable to a wired network; and a mobile information terminal connectable to a public radio network and to the base station, the mobile information terminal including:
a short range communicator which, in operation, communicates with the base station;a public radio communicator which, in operation, performs radio communication via the public radio network;a functional operator which, upon user selection, initiates a connection process or a disconnection process of a short range communication linkwith the base station;an incoming data retrieval operator, which is different from the functional operator;a screen; anda controller which, in operation,
when the functional operator is selected in a state in which the short range communication link is connected, executes the disconnection process of the short range communication link;when the functional operated operator is selected in a state in which the short range communication link is disconnected, executes the connection process of the short range communication link; andwhen the incoming data retrieval operator is selected in a state in which the short range communication link is disconnected, executes the connection process of the short range communication linkand displays incoming data, which was recorded in the base station while the short range communication link was disconnected, on the screen of the mobile information terminal.
