Radio communication system and mobile information terminal
First Claim
1. A radio communication system comprising:
- a base unit in compliance with a near filed communication protocol operable to connect with a public wired network; and
a mobile information terminal that includes a near field radio communicator operable to wirelessly connect with the base unit using the near field communication protocol, and that includes a public radio communicator operable to wirelessly connect with a public radio network comprising a cellular phone network, wherein;
the mobile information terminal is configured to, after a first time period of receiving no signal from the base unit or in response to a defined user operation performed on the mobile information terminal, enter into a first search mode of searching for the base unit at a first cycle for a second time period and, after the second time period of receiving no signal from the base unit, enter into a second search mode of searching for the base unit at a second cycle that is longer than the first cycle; and
the base unit, in operation,records one or more events that occur while the mobile information terminal is disconnected, andwhen the mobile information terminal is reconnected, transmits information relating to the one or more events to the mobile information terminal for display.

Abstract
An operation for reconnecting a mobile information terminal and a base unit, which is performed when a user returns home, is made easier, and a matter that has occurred in the base unit during his absence is displayed on the mobile information terminal. The mobile information terminal enters a sleep state when receiving no signal from the base unit. When the user performs a predetermined operation, the mobile information terminal returns from the sleep state, then searches for the base unit, and displays, on a display section, information relating to the matter that has occurred during his absence, the information being transmitted from the base unit when the terminal is reconnected to the base unit. Accordingly, the user can know, through a simple operation, the record of an incoming call received through a wired network, or an answering machine message that has occurred during his absence from the base unit.

8. A mobile information terminal comprising:
-
a near field radio communicator operable to wirelessly connect with a base unit of a radio communication system using a near field communication protocol, wherein the base unit is in compliance with the near field communication protocol; and a public radio communicator operable to wirelessly connect with a public radio network comprising a cellular phone network, wherein the mobile information terminal is configured to, after a first time period of receiving no signal from the base unit or in response to a defined user operation performed on the mobile information terminal, enter into a first search mode of searching for the base unit at a first cycle for a second time period, after the second time period of receiving no signal from the base unit, enter into a second search mode of searching for the base unit at a second cycle that is longer than the first cycle, and when reconnected with the base unit, receive from the base unit information relating to one or more events that have occurred while the mobile information terminal was disconnected from the base unit and display the received information. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
