Communication apparatus, image capturing apparatus, control method, and storage medium

An image capturing apparatus comprising:

• an image capturing unit configured to capture an image;
• a communication unit capable of executing, with an apparatus connecting to a network, communication related to transmission of a packet for discovery and communication for transmitting the image to a communication partner apparatus;
• a control unit configured to, after the communication apparatus is connected to an external apparatus via the network, control the communication unit to limit the communication with another external apparatus connecting to the network;
• and
• a determination unit configured to determine, in a case where the connection with the external apparatus is disconnected, whether the disconnection is performed by the external apparatus,
• wherein, in a case where reconnection to the network is performed after the connection to the external apparatus is disconnected and where it is determined that the disconnection is not performed by the external apparatus, the communication unit is controlled by the control unit to maintain the limitation for the communication with the other external apparatus and to transmit a reconnection notification to the external apparatus by unicast, and
• wherein, in a case where reconnection to the network is performed after connection to the external apparatus is disconnected and it is determined that the disconnection is performed by the external apparatus, the communication unit is controlled by the control unit to communicate with the other external apparatus without the limitation.

A control method for a communication apparatus that is capable of executing, with an apparatus connecting to a network, communication related to transmission of a packet for discovery and can control, after the communication apparatus is connected to an external apparatus via the network, the communication apparatus to limit the communication with another external apparatus connecting to the network, the method comprising:

• determining, in a case where the connection with the external apparatus is disconnected, whether the disconnection is performed by the external apparatus;
• in a case where reconnection to the network is performed after the connection to the external apparatus is disconnected and where it is determined that the disconnection is not performed by the external apparatus,
• controlling the communication apparatus to maintain the limitation for the communication with the other external apparatus, and
• controlling the communication apparatus to transmit a reconnection notification to the external apparatus by unicast, and
• in a case where reconnection to the network is performed after connection to the external apparatus is disconnected and it is determined that the disconnection is performed by the external apparatus, controlling the communication apparatus to communicate with the other external apparatus without the limitation.

A non-transitory computer-readable storage medium that stores a program for causing a computer, provided in a communication apparatus that is capable of executing, with an apparatus connecting to a network, communication related to transmission of a packet for discovery and can control, after the communication apparatus is connected to an external apparatus via the network, the communication apparatus to limit the communication with another external apparatus connecting to the network, to:

• determine, in a case where the connection with the external apparatus is disconnected, whether the disconnection is performed by the external apparatus;
• in a case where reconnection to the network is performed after the connection to the external apparatus is disconnected and where it is determined that the disconnection is not performed by the external apparatus,
• control the communication apparatus to maintain the limitation for the communication with the other external apparatus, and
• control the communication apparatus to transmit a reconnection notification to the external apparatus by unicast, and
• in a case where reconnection to the network is performed after connection to the external apparatus is disconnected and it is determined that the disconnection is performed by the external apparatus, control the communication apparatus to communicate with the other external apparatus without the limitation.
