communication device which has a predetermined function, and is present on a network identified by network identification information contained in the beacon detected by said detection means, in accordance with the network identification information; and
display means for selectably displaying
information associated with the wireless communication device detected by said search means so as to determine a wireless communication partner,
said second wireless communication device
comprises :
transmission means for, when search request information is detected in a wireless reception waiting state at a predetermined frequency, transmitting
information including self identification information as response information, and
when information of said second wireless
communication device displayed by said display means is selected, a process for establishing a communication between said first and second wireless communication devices is executed.
2. A wireless communication device comprising:
detection means for detecting a beacon at each frequency;
search means for searching for a wireless
communication device which has a predetermined function, and is present on a network identified by network identification information contained in the beacon detected by said detection means, in accordance with the network identification information; and
display means for selectably displaying
information associated with the wireless communication device detected by said search means so as to determine a wireless communication partner.
3. The device according to claim 2 , wherein said search means transmits search request information in accordance with the network identification information included in the beacon detected by said detection means so as to search for the wireless communication device having the predetermined function, and stores in a memory identification information of a wireless
communication device on a partner side included in a response to the search request information upon
reception of the response, and
said display means selectably displays the
identification information stored in the memory.

4. The device according to claim 2, wherein each of the wireless communication device and the partner wireless communication device comprises one of an image sensing device, a device for executing a print process of a sensed image, and a storage device for executing a storage process of a sensed image.
5. The device according to claim 2 , wherein when one of information displayed by said display means is selected before beacons for all frequencies are
detected, subsequent detection processes are aborted, and a connection process with a wireless communication device specified by the selected information is
executed.
6. The device according to claim 2 , wherein when no partner wireless communication device is found within a predetermined period of time, an error display is made.
7. The device according to claim 2 , further comprising:
determination means for determining if the beacon detected by said detection means is a beacon in an adhoc communication mode or a beacon in an
infrastructure communication mode, and
in that when said determination means determines that the detected beacon is the beacon in the adhoc communication mode, said search means transmits search request information toward a wireless communication processing device as a generation source of that beacon, and
when said determination means determines that the detected beacon is the beacon in the infrastructure mode, said search means transmits search request
information of a wireless communication processing device toward an access point.
8. The device according to claim 2 , further comprising registration means for registering, in a memory, information associated with connection to the partner wireless communication device, to which the wireless communication has been established.
9. The device according to claim 8 , further comprising a mode for executing a process for
establishing a wireless communication on the basis of the information registered by said registration means.
10. A wireless communication device comprising:
storage means for storing device identification information and network identification information of a partner to which the self wireless communication device has been connected previously;
instruction means for instructing one of a
history search mode that communicates with a desired partner wireless communication device stored in said storage means, and a new search mode that searches for a partner wireless communication device via a wireless communication, and communicates with the found partner wireless communication device;
beacon detection means for, when said instruction means instructs the new search mode, detecting a beacon;
search means for comparing network identification information included in the detected beacon with the network identification information stored in said storage means, making said detection means detect another beacon if the two pieces of network
identification information match, and searching for a partner wireless communication device to communicate with based on new network identification information if the new network identification information is detected; first display means for selectably displaying one device identification information found by said search means;
second display means for, when said instruction means instructs the history search mode, selectably displaying the device identification information stored in said storage means; and
wireless communication establishment process means for, when one device identification information displayed by one of said first and second display means is selected, executing a wireless communication
establishment process on the basis of the selected device identification information.

11. A wireless communication system having first and second wireless communication devices, wherein
said first wireless communication device
comprises :
determination means for determining a designated process type; and
display means for displaying information
associated with a device having a function of the process type determined by said determination means on the basis of signals informed by another devices,
said second wireless communication device
comprises :
informing means for informing of device
identification information indicating a self function, and
when information of said second wireless
communication device displayed by said display means is selected, a process for establishing a communication between said first and second wireless communication devices is executed.
12. A wireless communication device comprising:
determination means for determining a designated process type; and
display means for displaying information
associated with a device having a function of the process type determined by said determination means on the basis of signals informed by another devices.

13. A method of controlling a wireless
communication device, comprising:
a detection step of detecting beacons at a
plurality of frequencies;
a search step of searching for a wireless
communication device which has a predetermined function, and is present on a network identified by network identification information contained in the beacon detected in the detection step, in accordance with the network identification information; and
a display step of selectably displaying
information associated with the wireless communication device detected in the search step so as to determine a wireless communication partner.
14. A method of controlling a wireless
communication device, comprising:
a storage step of storing, in a memory, device identification information and network identification information of a partner wireless communication device which has been connected previously;
a determination step of determining an operator's instruction that instructs one of a history search mode that communicates with a desired partner wireless communication device stored in the memory, and a new search mode that searches for a partner wireless
communication device via a wireless communication, and communicates with the found partner wireless
communication device;
a search step of executing, when the operator instructs the new search mode, a beacon detection process, comparing network identification information included in the detected beacon with the network identification information stored in the memory, continuing a detection process of another beacon if the two pieces of network identification information match, and searching for a partner wireless communication device to communicate with based on new network
identification information if the new network
identification information is detected;
