Abstract
When a communication device detects another communication device operating as a providing device that provides a communication parameter and when a communication parameter has already been set between the communication device and a different communication device or when the communication device is participating in the same network as that in which the different communication device is present, the communication device transmits a session overlap notice to the detected communication device.
Claims19
A communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the communication device comprising:
- a search unit configured to search for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- a determination unit configured to determine whether or not a communication parameter for communicating between the communication device and a first communication device has already been set;
- and
- a transmission unit configured to transmit, when the search unit detects a second communication device, which is different from the first communication device, operating as a providing device and when the determination unit determines that the communication parameter for communicating between the communication device and the first communication device has already been set, a message to the second communication device for limiting an operation of the second communication device as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
A communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the communication device comprising:
- a search unit configured to search for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- a determination unit configured to determine whether or not a first communication device and the communication device are present in a same network;
- and
- a transmission unit configured to transmit, when the search unit detects a second communication device, which is different from the first communication device, operating as providing device and when the determination unit determines that the first communication device and the communication device are present in a same network, a message to the second communication device for limiting an operation of the second communication device as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
A communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the communication device comprising:
- a search unit configured to search for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- a setting unit configured to set the communication device to operate as a providing device in accordance with a search result obtained by the search unit;
- and
- a limiting unit configured to limit an operation of the communication device as a providing device when a message indicating that a plurality of providing devices are present is received after the setting unit sets the communication device to operate as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
A control method for a communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the control method comprising:
- searching for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- determining whether or not a communication parameter for communicating between the communication device and a first communication device has already been set;
- and
- transmitting, when a second communication device, which is different from the first communication device, operating as a providing device is detected and when it is determined that the communication parameter for communicating between the communication device and the first communication device has already been set, a message for limiting an operation of the second communication device as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
A control method for a communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the control method comprising:
- searching for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- determining whether or not a first communication device and the communication device are present in a same network;
- and
- transmitting, when a second communication device, which is different from the first communication device, operating as a providing device is detected and when it is determined that the first communication device and the communication device are present in a same network, a message for limiting an operation of the second communication device as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
A control method for a communication device for acting as a providing device or a receiving device and performing a communication parameter setting process, the providing device being configured to provide a communication parameter, the receiving device being configured to receive the communication parameter provided by the providing device, the control method comprising:
- searching for another communication device operating as a providing device, while the communication device is not set to operate as either the providing device or the receiving device;
- setting the communication device to operate as a providing device in accordance with the search result;
- and
- limiting operation of the communication device as a providing device when a message indicating that a plurality of providing devices are present is received after the communication device is set to operate as a providing device,
- wherein the message indicates that a plurality of providing devices are present.
