Abstract
A communication apparatus functioning as a master device denies participation by new communication apparatuses in a network in communication parameter configuration mode based on participation statuses of communication apparatuses functioning as slave devices in the network. The communication apparatus functioning as a master device establishes the network in communication parameter configuration mode between the communication apparatuses participating in the network, and configures communication parameters.
Claims9
A method executed by a communication apparatus for sharing a communication parameter for communication in a wireless network, the method comprising steps of:
- transmitting, by a communication apparatus, an inquiry message for inquiring about a management apparatus, which determines a providing apparatus for providing the communication parameter;
- determining, by the communication apparatus, whether the communication apparatus itself becomes the management apparatus according to a response message to the inquiry message;
- managing, by the management apparatus, a number of other communication apparatuses, which send request signal for sharing of the communication parameter;
- limiting, by the management apparatus, other communication apparatuses with which the communication parameter is to be shared, based on the managed number;
- acquiring, by the management apparatus, capability information of other communication apparatuses, which request sharing of the communication parameter;
- determining, by the management apparatus, the providing apparatus from among the management apparatus itself and said other communication apparatuses based on the capability information;
- and
- providing, by the providing apparatus, the communication parameter to other communication apparatuses, which are not determined as the providing apparatus.
A communication apparatus having a function of sharing a communication parameter in a wireless network, the apparatus comprising:
- a transmission unit configured to transmit an inquiry message for inquiring about a management apparatus, which determines a providing apparatus for providing the communication parameter;
- a first determination unit configured to determine whether the communication apparatus itself becomes the management apparatus according to a response message to the inquiry message;
- a management unit configured to manage, in a case where the communication apparatus itself is determined as the management apparatus, a number of other communication apparatuses, which send request signal for sharing of the communication parameter;
- a limiting unit configured to limit, in a case where the communication apparatus itself is determined as the management apparatus, other communication apparatuses with which the communication parameter is to be shared, based on the managed number;
- an acquisition unit configured to acquire, in a case where the communication apparatus itself is determined as the management apparatus, capability information of other communication apparatuses, which request sharing of the communication parameter;
- a second determination unit configured to determine, in a case where the communication apparatus itself is determined as the management apparatus, the providing apparatus from among the communication apparatus itself and said other communication apparatuses based on the acquired capability information;
- and
- a providing unit configured to provide, in a case where the communication apparatus itself is determined as the providing apparatus, the communication parameter to other communication apparatuses, which are not determined as the providing apparatus.
A non-transitory computer-readable storage medium storing a computer program for causing a computer included in a communication apparatus having a function for sharing a communication parameter in a wireless network to:
- transmit an inquiry message for inquiring about a management apparatus, which determines a providing apparatus for providing the communication parameter;
- determine whether the communication apparatus itself becomes the management apparatus according to a response message to the inquiry message;
- manage, in a case where the communication apparatus itself is determined as the management apparatus, a number of other communication apparatuses, which send request signal for sharing of the communication parameter;
- limit, in a case where the communication apparatus itself is determined as the management apparatus, other communication apparatuses with which the communication parameter is to be shared, based on the managed number;
- acquire, in a case where the communication apparatus itself is determined as the management apparatus, capability information of other communication apparatuses, which request sharing of the communication parameter;
- determine, in a case where the communication apparatus itself is determined as the management apparatus, the providing apparatus from among the communication apparatus itself and said other communication apparatuses based on the acquired capability information;
- and
- provide, in a case where the communication apparatus itself is determined as the providing apparatus, the communication parameter to other communication apparatuses, which are not determined as the providing apparatus.
