Abstract

A device capability attribute regarding a setting on communication parameters, and provision attribute information indicative of whether or not a communication terminal is in a state that it can provide communication parameters to another communication terminal are stored in advance. The communication terminal, where the device capability attribute has at least a provision capability of the communication parameters, is selected as a provision device. In a case where there are plural communication terminals where the device capability attribute has a communication parameter provision capability, a communication terminal where the device capability attribute has the communication parameter provision capability only is preferentially selected. In a case where the device capability attributes of respective communication terminals are equal, a communication terminal storing the provision attribute information indicative of the state that it can provide the communication parameters is selected as a provision device.

Claims23

Dependent claims

A communication apparatus comprising:

at least one processor;
and
at least one memory storing code to be executed by the at least one processor, wherein the at least one processor executes the code to function as:
a search unit to search a partner apparatus to communicate with a wireless communication being compliant with an IEEE 802.11 standard;
a transmission unit to transmit a first value stored in the communication apparatus to the partner apparatus searched by the search unit;
a reception unit to receive a second value stored in the partner apparatus from the partner apparatus;
and
a determination unit to compare the first value with the second value, determine (i) that the communication apparatus operates as an apparatus for providing a wireless parameter of the wireless communication being compliant with an IEEE 802.11 standard to the partner apparatus if the first value is greater than the second value, and determine (ii) that the communication apparatus operates an apparatus for receiving the wireless parameter of the wireless communication being compliant with an IEEE 802.11 standard from the partner apparatus if the first value is less than the second value,
wherein the search unit, the transmission unit and the reception unit communicate through a predetermined frequency channel,
wherein the communication apparatus communicates with the partner apparatus based on the wireless parameter through a frequency channel that is selected by the communication apparatus operates as the apparatus for providing the wireless parameter to the partner apparatus, and
wherein the communication apparatus notifies an error if the communication apparatus fails to connect with the partner apparatus.

8 more elements

A control method of a communication apparatus, the method comprising:

searching a partner apparatus to communicate with a wireless communication being compliant with an IEEE 802.11 standard;
transmitting a first value stored in the communication apparatus to the partner apparatus searched in the searching;
receiving a second value stored in the partner apparatus from the partner apparatus;
comparing the first value with the second value;
and
determining (i) that the communication apparatus operates as an apparatus for providing a wireless parameter of the wireless communication being compliant with an IEEE 802.11 standard to the partner apparatus if the first value is greater than the second value, and determining (ii) that the communication apparatus operates an apparatus for receiving the wireless parameter of the wireless communication being compliant with an IEEE 802.11 standard from the partner apparatus if the first value is less than the second value,
wherein, in the searching, the transmitting and the receiving, communication are performed through a predetermined frequency channel,
wherein the communication apparatus communicates with the partner apparatus based on the wireless parameter through a frequency channel that is selected by the communication apparatus operates as the apparatus for providing the wireless parameter to the partner apparatus, and
wherein the communication apparatus notifies an error if the communication apparatus fails to connect with the partner apparatus.
