Abstract

A method for establishing a wireless connection between a first wireless device provided in a computer and a second wireless device, wherein group information that identifies the first wireless device is created and set for the first wireless device. The group information is transmitted to the second wireless device and is set for it. The first wireless device creates identification information that identifies the second wireless device with the group information to set it for the second wireless device. The first wireless device uses both of the group information and identification information to specify the second wireless device.

Claims

1. A method for establishing a wireless connection between a first wireless device provided in a computer and a second wireless device, said method comprising the steps of:

creating group information that identifies said first wireless device in the first wireless device and setting the group information for said first wireless device;

transmitting the group information from said first wireless device to said second wireless device;

setting the group information for said second wireless device;

creating identification information that identifies said second wireless device with the group information set in the first wireless device;

transmitting the identification information from said first wireless device to said second wireless device;

setting the identification information for said second wireless device; and

using the group information and the identification information to specify said second wireless device to establish the wireless connection between said first and second wireless devices.

2. The method in accordance with claim 1, wherein the group information is set at a startup of said first wireless device.

3. The method in accordance with claim 1, wherein said first wireless device transmits the group information to said second wireless device during idle time.

4. The method in accordance with claim 1, wherein, said first wireless device transmits information to be hidden as well as the group information.

5. The method in accordance with claim 1, wherein said first wireless device transmits the identification information to said second wireless device during idle time.

6. The method in accordance with claim 1, wherein the identification information is a USB address.

7. The method in accordance with claim 1, further comprising the step of creating a random number for identifying said second wireless device temporally in the second wireless device.

8. The method in accordance with claim 7, further comprising the step of transmitting the group information and the random number from the second wireless device to the first wireless device.

9. The method in accordance with claim 8, wherein said first wireless device transmits the random number to said second wireless device as well as the identification information.

10. A method for establishing a wireless connection between a first wireless device provided in a computer and a second wireless device, said method comprising the steps of:

receiving group information that identifies said first wireless device in the first wireless device and setting the group information for said first wireless device;

setting the group information for said second wireless device;

receiving identification information that identifies said second wireless device with the group information set in the first wireless device;

setting the identification information for said second wireless device; and

using the group information and the identification information to specify said second wireless device to establish the wireless connection between said first and second wireless devices.

11. A system for establishing a wireless connection between a first wireless device provided in a computer and a second wireless device, said system comprising:

a group information creating circuit for creating group information that identifies said first wireless device;

a first storage for storing the group information;

an identification information creating circuit for creating identification information that identifies said second wireless device; and

a second storage for storing the group information and identification information,

the group information and the identification information being used to specify said second wireless device to be wirelessly connected to said first wireless device to establish the wireless connection between said first and second devices.

12. The system in accordance with claim 11, wherein the group information is set at a startup of said first wireless device.

13. The system in accordance with claim 11, further comprising a transmitter for transmitting the group information and the identification information to said second wireless device to have said second wireless device set the group information.

14. The system in accordance with claim 13, wherein said transmitter transmits the group information and the identification information during idle time.

15. The system in accordance with claim 13, wherein said transmitter transmits information to be hidden as well as the group information.

16. A wireless device provided in a computer, comprising:

a group information creating circuit for creating group information that identifies said wireless device;

a storage for storing the group information;

an identification information creating circuit for creating identification information that identifies another wireless device to be connected wirelessly to said wireless device; and

a transmitter/receiver for transmitting the group information and the identification information to the other wireless device.

17. A wireless device provided in a device other than a computer, comprising:

a transmitter/receiver for receiving group information and identification information transmitted from another wireless device which is provided in the computer, the group information identifying the other wireless device, the identification information identifying said wireless device; and

a storage for storing the group information and the identification information.
