Patent application number | Description | Published |
20120219008 | NETWORK SYSTEM AND CONTROL METHOD THEREOF - Disclosed is a network system and a control method thereof, the network system including a gateway connected to a plurality of home appliances through a home area network, an outdoor apparatus connected to the gateway through a network, and a dynamic domain name system (DDNS) server to manage dynamic internet protocol (IP) address information about an apparatus using a dynamic IP address. A communication connection is achieved through a dynamic IP between a gateway inside the home and an apparatus outside the home in a smart grid network environment, so a user can easily access in-home services based on a dynamic IP. In addition, unauthorized traffic, which may be introduced into the home, is automatically blocked, so that the quality of the home network service is improved. | 08-30-2012 |
20120233468 | AUTHENTICATING METHOD OF COMMUNICATING CONNECTION, GATEWAY APPARATUS USING AUTHENTICATING METHOD, AND COMMUNICATION SYSTEM USING AUTHENTICATING METHOD - An authenticating method of communicating connection between a terminal and a gateway apparatus, the method including transmitting authentication information and first intrinsic identification information that is intrinsic identification information of the terminal from the terminal to the gateway apparatus and requesting the authentication; authenticating the communicating connection by using at least one of the first intrinsic identification information and the authentication information; and when the authenticating is successful, generating at least one authentication key by using at least one of the first intrinsic identification information and second intrinsic identification information that is intrinsic identification information of the gateway apparatus, thereby increasing communication security between the terminal and the gateway apparatus. | 09-13-2012 |
20130149966 | COMMUNICATION METHOD, APPARATUS, AND SYSTEM - Provided are a communication method, apparatus, and system. The communication method comprises registering addresses of opponent devices to communicate with in advance between a ZigBee coordinator and an end device, thus preventing an unauthorized device from joining a network or avoiding unnecessary joining due to a user's mistake. | 06-13-2013 |
20130177029 | PROTOCOL CONVERSION APPARATUS AND PROTOCOL CONVERSION METHOD - A protocol conversion apparatus and a protocol conversion method. The protocol conversion apparatus includes a first control to analyze first protocol data received through a first channel, a protocol mapper to determine whether protocol conversion is required for the first protocol data, and a second control to create second protocol data associated with the first protocol data based on a result of the determination, and to transfer the second protocol to a second channel. | 07-11-2013 |
20130265061 | METHOD AND APPARATUS FOR MANAGING ELECTRONIC APPLIANCE - A method and apparatus for managing an electronic appliance, which determines an abnormality of the electronic appliance, such as a malfunction or worn out of the electronic appliance, based on power consumption information measured in the electronic appliance while an operation requested by a user of the electronic appliance is performed by the electronic appliance, and past power consumption information about the same operation performed by the same electronic appliance, and a non-transitory computer-readable recording medium having recorded thereon a program to execute the method. | 10-10-2013 |
20140204867 | METHOD AND TERMINAL OF TRANSMITTING AN UPLINK SIGNAL WITH FEWER TRANSMISSION RESOURCE BLOCKS TO PREVENT A LOWERING IN REFERENCE SENSITIVITY IN INTRA-BAND NON-CONTIGUOUS UPLINK CARRIER AGGREGATION - There is provided a method of transmitting an uplink for reference sensitivity test for intra-band non-contiguous CA in LTE-A system. The method may comprise: if a carrier aggregation (CA) is configured, if the configured CA corresponds to an intra-band CA, and if the configured CA corresponds to non-contiguous CA, transmitting an uplink on a primary component carrier using allocated resource blocks (RBs). if a channel bandwidth by an aggregation of the primary component carrier and a secondary component carrier is at least one of 25 RBs, 50 RBs, 75 RBs and 100 RBs and if a gap between two sub-blocks corresponds to a predetermined range, the number of the allocated resource block (RB) in the primary component carrier may be limited to 10 to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier. | 07-24-2014 |
