Abstract

In a radio communication connection destination specifying method of establishing a link between electronic information communication devices in a radio communication system which executes radio communication using a radio wave, device identification information of an electronic information communication device of a connection request source is transmitted to an electronic information communication device of a connection request destination using, as radio communication, radio communication with strong directivity. The electronic information communication device of the connection request destination specifies the electronic information communication device of the connection request source on the basis of the transferred device identification information and establishes the link.

Claims

1. A radio communication method of establishing a link between communication devices in a radio communication system, comprising:

transferring device identification information of a communication device of a connection request source to a communication device of a connection request destination using a radio communication with strong directivity;

transmitting an inquiry request from the communication device of the connection request destination;

receiving, at the communication device of the connection request destination, inquiry responses from a plurality of communication devices;

recalling the transferred device identification information of the communication device of the connection request source, and comparing the transferred device identification information to identification information contained within the received inquiry responses; and

establishing a link between the connection request source and the connection request destination on the basis of a match between the transferred device identification information of the communication device of the connection request source, and identification information contained within one of the received inquiry responses.

2. The method according to claim 1, wherein the radio communication system is a short-distance radio data communication system.

3. The method according to claim 1, wherein the radio communication with strong directivity is infrared communication.

4. The method according to claim 3, wherein the infrared communication uses a connectionless service.

5. The method according to claim 3, wherein the infrared communication uses a connection-oriented service.

6. The method according to claim 1, wherein the device identification information comprises a short-distance radio data communication device address.

7. The method according to claim 1, wherein the device identification information comprises a short-distance data communication device name.

8. The method according to claim 1, further comprising:

before transferring the device identification information, causing the communication device of the connection request source to face the communication device of the connection request destination.

9. The method according to claim 1, further comprising:

setting a receiving state in the communication device of the connection request destination;

if no device identification information is transferred during the transferring step, within a predetermined time after the receiving state is set, transmitting the inquiry request to all communication devices, receiving the inquiry responses, and notifying a user of pieces of device identification information contained in the received inquiry responses; and

establishing the link upon determining the electronic information device selected by a user operation as the connection request source.
