Abstract

This invention has as its object to set a one-to-one relationship upon establishing a wireless communication channel between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information even in an environment including a plurality of wireless communication devices, and to assure simple user'"'"'s operations at least until the communication channel is established. To this end, when the user inputs a wireless communication channel establishment instruction to both a digital camera and printer having wireless communication functions, these devices execute wireless communication establishment processes within an allowable time period which is specified by a time set in a timer and a retry count. When the devices can seize each other within that time period, the communication channel is established. After that, the digital camera sends a sensed image to the printer, which prints the sensed image.

Claims

1. A wireless communication device, comprising:

a detector adapted to detect an operation for setting a communication parameter used for entering into a wireless network created by a base station;

a connection unit adapted to wirelessly connect with another wireless communication device different from the base station;

a timer adapted to count an elapsed time; and

a reception unit adapted to receive, from said another wireless communication device without intervention of the base station, the communication parameter used for entering into the wireless network created by the base station while the wireless communication device does not enter the wireless network created by the base station, in a case that said connection unit connects with said another wireless communication device before the elapsed time period counted by said timer becomes a predetermined time period, wherein

the communication parameter includes information related to at least one of a frequency channel, a service set ID, or information related to an encryption, and

at least one of the detector, the connection unit, the timer and the reception unit is achieved by that a processor executes a program stored in a memory.

2. The wireless communication device according to claim 1, wherein the reception unit receives, from said another wireless communication device, the communication parameter in a case that said connection unit connects with said another wireless communication device before the elapsed time period counted by said timer becomes a predetermined time period from when the detector detects the operation.

3. The wireless communication device according to claim 2, wherein, in a case that multiple other wireless communication devices are detected within the predetermined time period, the process for setting the communication parameter is aborted as a failure.

4. The wireless communication device according to claim 1, wherein, in a case that multiple other wireless communication devices are detected within the predetermined time period, the process for setting the communication parameter is aborted as a failure.

5. The wireless communication device according to claim 1, wherein, the wireless communication device communicates with said another wireless communication device via the base station.

6. The wireless communication device according to claim 1, further comprising a disconnection unit adapted to disconnect the communication with said another wireless communication device in a case that the communication parameter is received by the reception unit.

7. The wireless communication device according to claim 1, wherein the wireless communication device communicates wirelessly in a first communication method and a second communication method,

wherein the reception unit receives, using the first communication method, the communication parameter to be used in the second communication method.

8. The device according to claim 1, wherein said reception unit does not receive the communication parameter used for entering into the wireless network created by the base station in a case that said correction unit connects with said another wireless communication device after the elapsed time period counted by said timer becomes a predetermined time period.

9. A wireless communication device, comprising

a detector adapted to detect an operation for setting a communication parameter used for entering into a wireless network created by a base station;
