COMMUNICATION APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

This invention relates to a communication apparatus capable of facilitating a connection with a device in a network by using a discovery protocol for discovering a device in a network. By using a plurality of types of discovery protocols, the communication apparatus transmits search commands to search devices in the network. A device is selected based on pieces of device information which are transmitted from devices in the network in response to the search commands and each of which contains the type of discovery protocol supported by the device. Based on a discovery protocol supported by the selected device, the communication apparatus transmits a notification signal to notify the device in the network of the presence of the communication apparatus.

主权项

1. A communication apparatus which establishes a connection with a device in a network by using a discovery protocol for discovering the device, comprising:
a first transmission unit configured to transmit a plurality of search commands using a plurality of types of discovery protocols to search devices in the network; a first reception unit configured to receive pieces of device information transmitted from devices in the network in response to the search commands, the device information containing a type of discovery protocol supported by the corresponding device; a first selection unit configured to select a device based on the pieces of device information received by said first reception unit; and a second transmission unit configured to transmit a notification signal to notify devices in the network of presence of the communication apparatus after the selection by said first selection unit, the notification signal being based on the discovery protocol supported by the device selected by said first selection unit.
