Abstract

When a cellular phone 11 is placed in an area near a fixed terminal 12, a peculiar device address sent from the fixed terminal 12 is received, and a link of a bluetooth system with the fixed terminal 12 is established by using the peculiar device address.

Claims

1. A personal digital assistant, comprising:

address receiving means for receiving a device address peculiar to a connecting device in an area near the connecting device; and

link establishing means for establishing a link of a bluetooth system with the connecting device by using the device address received by the address receiving means.

2. A personal digital assistant according to claim 1, wherein the address receiving means receives an electric power from the connecting device and performs a receiving operation of the device address.

3. A personal digital assistant according to claim 1, wherein the link establishing means performs a page sequence prescribed in a specification of the bluetooth system and establishes the link of the bluetooth system with the connecting device.

4. A personal digital assistant according to claim 1, further comprising:

displaying means for displaying the device address received by the address receiving means.

5. A radio communication system, comprising:

a connecting device for sending a particular device address; and

a personal digital assistant for receiving the peculiar device address sent from the connecting device in an area near the connecting device and establishing a link of a bluetooth system with the connecting device by using the device address.

6. A radio communication system according to claim 5, wherein the connecting device is formed of a fixed terminal.

7. A radio communication system according to claim 5, wherein the connecting device is formed of another personal digital assistant.

8. A link establishing method, comprising the steps of:

receiving a peculiar device address sent from a connecting device in an area near the connecting device; and

establishing a link of a bluetooth system with the connecting device by using the device address.
