20120272082 | COMMUNICATION APPARATUS COMMUNICATING WITH IPSEC, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR - A communication apparatus that is capable of enabling communication even when IPsec life time information is taken over. The communication apparatus is connected to a network via a network interface device and operates in a first power mode or a second power mode with less power consumption. A notification unit notifies the network interface device of IPsec life time information when shifting to the second power mode from the first power mode. A storage unit stores first time information showing time of shifting to the second power mode from the first power mode. An acquisition unit acquires the life time information from the network interface device when shifting to the first power mode from the second power mode. A correction unit corrects the life time information based on second time information showing time of shifting to the first power mode from the second power mode and the first time information. | 10-25-2012 |
20130308642 | DATA COMMUNICATION APPARATUS FOR COMMUNICATING WITH EXTERNAL APPARATUS VIA NETWORK, CONTROL METHOD OF THE DATA COMMUNICATION APPARATUS, AND STORAGE MEDIUM - A communication apparatus communicating with an external apparatus via a relaying device is provided. The communication apparatus includes a communication unit configured to perform communication with the relaying device, and a control unit configured to reduce a communication speed of the communication unit to a lower speed if the communication apparatus is to be shifted from a first power mode to a second power mode in which power consumption is lower than that in the first power mode. The communication unit, if the communication apparatus shifts to the second power mode, transmits identification information of the communication apparatus to the relaying device using a first method, and after a predetermined time has passed, transmits the identification information to the relaying device using a second method. | 11-21-2013 |
20140013139 | IMAGE PROCESSING APPARATUS, METHOD FOR CONTROLLING THE SAME AND STORAGE MEDIUM - An image processing apparatus of one aspect of the present invention determines, upon receipt of a packet in a power saving state at a second communication rate slower than a first communication rate, whether or not to change the communication rate, on the basis of a communication protocol type and a port number, and an attribute of the packet represented by a data section of the packet. If the communication protocol type, the port number, and the attribute of the received packet indicate a request for a service predetermined as a network service that corresponds to the first communication rate, the image processing apparatus changes the communication rate from the second communication rate to the first communication rate at the time of shifting from the power saving state to the normal power state so as to provide the service. | 01-09-2014 |
20140164807 | INFORMATION PROCESSING APPARATUS, CONTROL METHOD OF INFORMATION PROCESSING APPARATUS, AND STORAGE MEDIUM - Whether to enable a packet discarding mode is designated and, if an information processing apparatus operates in a power saving mode and the packet discarding mode is enabled, the information processing apparatus determines processing for a received packet based on a proxy response pattern, a WOL pattern, and a discard pattern, and, if the information processing apparatus operates in the power saving mode and the packet discarding mode is disabled, the information processing apparatus determines processing for the received packet based on the proxy response pattern and the WOL pattern without using the discard pattern. | 06-12-2014 |
20140240768 | COMMUNICATION APPARATUS, CONTROL METHOD OF COMMUNICATION APPARATUS, AND STORAGE MEDIUM - When a service of interest is specified, a communication apparatus searches other communication apparatuses capable of providing the specified service and establishes a wireless communication with the specified communication apparatus. | 08-28-2014 |
20140268223 | COMMUNICATION APPARATUS, METHOD FOR CONTROLLING THE SAME, STORAGE MEDIUM, AND PRINTING APPARATUS - A communication apparatus includes a first communication unit for executing direct wireless communication between an external apparatus and the communication apparatus in which one of the external apparatus and the communication apparatus serves as an access point, and a second communication unit for executing communication between the external apparatus and the communication apparatus in a different way from the communication by the first communication unit. If it is determined that the communication which the communication apparatus is executing is the communication by the second communication unit, a selection screen is displayed so as to enable a user to select a desired service, and if it is determined that the communication which the communication apparatus is executing is the communication by the first communication unit, the selection screen is displayed so as to prevent the user from selecting the specific service. | 09-18-2014 |
20140380074 | INFORMATION PROCESSING APPARATUS, CONTROL METHOD FOR INFORMATION PROCESSING APPARATUS, AND STORAGE MEDIUM - When a printing apparatus operates in a normal power mode, a control unit specifies a time of receipt of a packet and a reception interval between packets by using an RTC. On the other hand, when the printing apparatus operates in a power-saving mode, a communication unit specifies a time of receipt of a packet and a reception interval between packets on the basis of time-of-day information acquired from an SNTP server. | 12-25-2014 |
20150055163 | COMMUNICATION APPARATUS, METHOD FOR CONTROLLING THE SAME, STORAGE MEDIUM, AND PRINTING APPARATUS - A communication apparatus includes a first communication unit for executing direct wireless communication between an external apparatus and the communication apparatus in which one of the external apparatus and the communication apparatus serves as an access point, and a second communication unit for executing communication between the external apparatus and the communication apparatus in a different way from the communication by the first communication unit. If it is determined that the communication which the communication apparatus is executing is the communication by the second communication unit, a selection screen is displayed so as to enable a user to select a desired service, and if it is determined that the communication which the communication apparatus is executing is the communication by the first communication unit, the selection screen is displayed so as to prevent the user from selecting the specific service. | 02-26-2015 |
