Portable terminal device with built-in GPS
First Claim
1. A portable terminal device with built-in GPS, comprising:
- a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information;
a GPS radio part for receiving data from a GPS (global positioning system) satellite;
a storage unit for storing the data received in the telephone radio part;
a map information part for storing map information; and
a control unit for performing processing such that a designated movement range of another portable terminal device with built-in GPS is set on the map stored in the map information part, data on the designated movement range are sent to said another portable terminal device with built-in GPS, and data on the current position of said another portable terminal device with built-in GPS, in which the designated movement range has been set, computed by said another portable terminal device with built-in GPS are received.

Abstract
A portable terminal device with built-in GPS (global positioning system) has: a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information; a GPS radio part for receiving data from a GPS satellite; a storage unit for storing the data received in the telephone radio part; a map information part for storing map information; and a control unit for setting the designated movement range of another portable terminal device with built-in GPS on the map stored in the map information part then sending it to the another portable terminal device, and receiving data on the current position of the another portable terminal device to be computed by itself.

5. A portable terminal device with built-in GPS, comprising:
-
a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information; a GPS radio part for receiving data from a GPS (global positioning system) satellite; a storage unit for storing the data received in the telephone radio part; a map information part for storing map information; and a control unit which computes a current position based on data obtained through the GPS radio part and, when the computed current position is deviated from a designated movement range set by another portable terminal device with built-in GPS, sends notification of the deviation from the designated movement range to said another portable terminal device with built-in GPS, and further sends said computed data on the current position to said another portable terminal device with built-in GPS. - View Dependent Claims (6, 7, 8, 9)

10. A portable terminal device with built-in GPS, comprising:
-
a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information; a GPS radio part for receiving data from a GPS (global positioning system) satellite; a storage unit for storing the data received in the telephone radio part; a map information part for storing map information; and a control unit comprising setting means for setting the designated movement range of another portable terminal device with built-in GPS on the map stored in the map information part and for sending the set designated movement range to said another portable terminal device with built-in GPS, means for acquiring data on the current position of said another portable terminal device with built-in GPS with the designated movement range set, said current position having been computed by said another portable terminal device with built-in GPS based on data received from the GPS satellite, means for computing its own current position based on data received from the GPS satellite through the GPS radio part, and means which, when the designated movement range has been set by another portable terminal device with built-in GPS, makes a judgment on whether or not the current position has deviated from the designated movement range.

11. A portable terminal device with built-in GPS, comprising:
-
a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information; a GPS radio part for receiving data from a GPS (global positioning system) satellite; a storage unit for storing the data received in the telephone radio part; and a control unit comprising setting means for setting the designated movement range of another portable terminal device with built-in GPS on a map downloaded, through the portable telephone radio part, from a position information server for providing map information and for sending the set designated movement range to said another portable terminal device with built-in GPS, means for undergoing setting of the designated movement range by another portable terminal device with built-in GPS, means for acquiring data on the current position of said another portable terminal device with built-in GPS with the designated movement range set, said current position having been computed by said another portable terminal device with built-in GPS based on data received from the GPS satellite, means for computing its own current position based on data received from the GPS satellite through the GPS radio part, and judgment means which, when the designated movement range has been set by another portable terminal device with built-in GPS, makes a judgment on whether or not the current position has deviated from the designated movement range. - View Dependent Claims (12, 13, 14)

15. A portable terminal device with built-in GPS, comprising:
-
a telephone radio part for wirelessly transmitting and receiving latitude information and longitude information; a GPS radio part for receiving data from a GPS (global positioning system) satellite; a storage unit for storing the data received in the telephone radio part and past current position data; and a control unit comprising means for acquiring data on the current position of another portable terminal device with built-in GPS computed by said another portable terminal device with built-in GPS based on data received from the GPS satellite, means for computing its own current position based on data received from the GPS satellite through the GPS radio part, speed computation means for determining movement speed based on movement distance for each past positioning stored in the storage unit, judgment means for making a judgment on whether or not the movement speed determined by the speed computation means has exceeded a set upper movement speed limit, and means for, when the result of the judgment by the judgment means is that the movement speed has exceeded the upper movement speed limit, informing another portable terminal device with built-in GPS of the fact that the movement speed has exceeded the upper movement speed limit. - View Dependent Claims (16)
