Abstract

A communication device to be used in an ad hoc network environment for enabling the user to utilize an application easily with a desired partner. After a communicable communication device was discovered, a service information provided by the communication device is acquired to display only the selected communication devices in accordance with the service information. The user selects the communication partner and causes the communication device to execute a predetermined application.

Claims

1-10. -10. (canceled)

11. A communication device having a radio interface, comprising:

a radio communication unit configured to exchange messages wirelessly with other devices existing around within a certain range;

a detection unit configured to detect other devices, by executing a station discovering procedure using the radio communication unit;

a designating unit configured to designate a service to execute;

an acquiring unit configured to acquire attribute information for each other device using the radio communication unit, the attribute information relating to whether the other device is capable to do the selected service;

a display unit configured to firstly display the other devices detected by the detection unit, and then secondly display such devices that are capable to do the selected service by eliminating other devices that are not capable to do the selected service; and

a selecting unit configured to select at least one of other devices that are capable to do the selected service.

12. The communication device according to claim 11, wherein the display unit displays each other device in an image or icon on a screen and the selecting unit selects the selected other device corresponding to the image or icon being appointed by a user.

13. The communication device according to claim 12, wherein each other device is displayed on the screen with the name of the other device.

14. The communication device according to claim 11, further comprising an application executing unit configured to execute an application when an instruction is received from the selected other device through the radio communication unit.
