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 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, comprising the steps of:

transferring device identification information of an electronic information communication device of a connection request source to an electronic information communication device of a connection request destination using, as radio communication, radio communication with strong directivity; and

causing the electronic information communication device of the connection request destination to specify the electronic information communication device of the connection request source on the basis of the transferred device identification information and to establish the link.

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

3. A method according to claim 1, wherein the transfer step comprises the step of transferring the device identification information using infrared communication as the radio communication with strong directivity.

4. A method according to claim 3, wherein the transfer step comprises the step of transferring the device identification information using a connectionless service as the infrared communication.

5. A method according to claim 3, wherein the transfer step comprises the step of transferring the device identification information using a connection-oriented service as the infrared communication.

6. A method according to claim 1, wherein the transfer step comprises the step of transferring a short-distance radio data communication device address as the device identification information.

7. A method according to claim 1, wherein the transfer step comprises the step of transferring a short-distance radio data communication device name as the device identification information.

8. A method according to claim 1, further comprising the step of, before transfer of the device identification information, causing the device of the connection request source to face the device of the connection request destination.

9. A method according to claim 8, wherein

the method further comprises the steps of

upon receiving the device identification information, transmitting an inquiry request from the electronic information device of the connection request destination to all electronic information devices including the connection request source, and

upon receiving the inquiry request, returning an inquiry response from all the electronic information devices including the connection request source to the electronic information device of the connection request destination, and

the link establishment step comprises the step of establishing the link upon determining that the electronic information device for which the device identification information received for the first time matches that received for the second time is the connection request source.

10. A method according to claim 9, wherein

when no device identification information is received from the electronic information device of the connection request source within a predetermined time after a receiving state is set, the inquiry request is transmitted from the electronic information device of the connection request destination to all the electronic information devices including the connection request source,

a user is notified of pieces of device identification information contained in inquiry responses returned from all the electronic information devices including the connection request source upon receiving the inquiry request, and

the link is established upon determining the electronic information device selected by user'"'"'s operation as the connection request source.
