A MSK refreshing method MSK includes when receiving a first Media Access Control (MAC) message including MSK refresh indication information from a Base Station (BS), generating, at a Mobile Station (MS), an Extended Master Session Key (EMSK)_Hash by applying a hash function to an EMSK and sending a second MAC message including the EMSK_Hash, sending, at the BS, a context request message including the EMSK_Hash to an Access Service Network GateWay (ASN-GW), sending, at the ASN-GW, an authentication request message including the EMSK_Hash to an authentication server, when receiving the authentication request message including the EMSK_Hash, confirming, at the authentication server, the same EMSK as the MS based on the EMSK_Hash, determining an MSK | 05-05-2011 |
20110128936 | METHOD AND APPARATUS FOR SUPPORTING IDLE MODE HANDOVER IN HETEROGENEOUS WIRELESS COMMUNICATION - A method for supporting an idle mode handover of an Single Radio Mobile Station (SR MS) by a target Access Service Network GateWay (ASN_GW) in a heterogeneous wireless communication system is disclosed. The method includes, upon detecting that an operation mode of the SR MS is to be changed from an idle mode to an active mode, acquiring an address of a Home Agent (HA) of the SR MS from a preregistered ASN_GW with which the SR MS has performed a preregistration operation, upon detecting that a Base Station (BS) is to set up a path with the preregistered ASN_GW, transmitting a message, including the address of the HA and requesting to set the target ASN_GW as a new Foreign Agent (FA) of the SR MS, to the preregistered ASN_GW, and upon receiving a message, requesting to register the target ASN_GW as the new FA of the SR MS, from the preregistered ASN_GW, setting up a data path with the HA, and then registering the target ASN_GW as the new FA of the SR MS. | 06-02-2011 |
20120208571 | METHOD AND APPARATUS FOR PEER-TO-PEER SERVICE IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for providing a Peer-to-Peer (P2P) service in a wireless communication system. A method of a server for providing the P2P service includes receiving a P2P service request signal comprising information of contents desired by a particular Mobile Station (MS); selecting at least one MS from MSs having the contents; establishing a traffic path between the particular and the selected MS; and transmitting information of the selected MS to the particular MS. | 08-16-2012 |
20120221677 | SERVER FOR PROVIDING TRAFFIC IMAGE TO USER DEVICE, AND THE USER DEVICE - A server for providing a traffic image to a user device includes a location information receiving unit which receives information relating to a respective location of each of a plurality of vehicles, a location management unit which receives information relating to a particular area from a user device, and which detects at least one vehicle located within the particular area based on the location information, an information sending unit which sends information relating to the at least one detected vehicle to the user device, an image requesting unit which receives information relating to a vehicle selected from among the at least one detected vehicle from the user device, and which requests, from a device installed in the selected vehicle, transmission of a traffic image of the selected vehicle, and an image providing unit which receives the image and which provides the traffic image to the user device. | 08-30-2012 |
20130284969 | R-FE-B SINTERED MAGNET WITH ENHANCED MECHANICAL PROPERTIES AND METHOD FOR PRODUCING THE SAME - Disclosed are an R—Fe—B sintered magnet and a method for producing the same. More specifically, provided is an R—Fe—B (R=Nd, Dy, Pr, Tb, Ho, La, Ce, Sm, Gd, Er, Tm, Yb, Lu or Th) sintered magnet having a structure in which R | 10-31-2013 |
20140165160 | METHOD AND APPARATUS FOR CONTROLLING ACCESS BETWEEN HOME DEVICE AND EXTERNAL SERVER IN HOME NETWORK SYSTEM - A method for controlling access between home devices and servers in a home network system is provided. The method includes determining whether first access of the home devices to each of the servers and second access of the servers to each of the home devices is restricted, and controlling the first access and second access based on respective access rights established according to the determination. | 06-12-2014 |
20140255307 | CONTRAST MEDIUM COMPOSITION AND METHOD OF BIO IMAGINATION USING THE SAME - The present invention relates to contrast medium composition and a method of bio imagination using the same. The contrast medium composition of the present invention includes a biomolecule, DNA nanostructure, as an active ingredient, is fundamentally non-cytotoxic and non-immunogenic and is not likely to induce safety problems that may be observed in other organic or inorganic contrast medium composition. In addition, the contrast medium composition of the present invention not only facilitates diagnosis of disease through sufficient contrast enhancement effect by showing excellent cellular uptake and intracellular stability and can visualize even SLNs which is difficult to be visualized traditionally, so can judge metastasis of cancer easily and apply lower invasive treatment. | 09-11-2014 |
20140362771 | APPARATUS AND METHOD FOR CONTROLLING LOCAL AREA COMMUNICATION CONNECTION BY MEANS OF WIRELESS TERMINAL DEVICE - An apparatus and a method for controlling a connection to a local area wireless communication network on the basis of a communication environment by means of a wireless terminal device are provided. To this end, the wireless terminal device collects information regarding a neighboring base station that constitutes a public communication network by means of a cell search, and determines whether it is possible to connect to a local area communication network on the basis of the collected information regarding the neighboring base station. If it is determined to be possible to connect to a local area communication network, the wireless terminal device makes an attempt to connect to a pre-registered wireless connection device on the basis of the collected information regarding the neighboring base station. | 12-11-2014 |
20150087278 | METHOD AND APPARATUS FOR CONTROLLING DEVICES FOR SMART HOME SERVICE - A method and apparatus for controlling devices for a smart home service are provided. The method includes grouping devices to receive at least one command simultaneously from among devices registered to the smart home service into a group for one mode, generating mode configuration information for each mode including grouped devices for the mode and at least one command for the mode, transmitting the mode configuration information for each mode to the registered devices, selecting one of each mode for which the mode configuration information has been generated, and transmitting a mode activation request for activating the selected mode to the registered devices. | 03-26-2015 |
20150089624 | SECURITY MANAGEMENT METHOD AND APPARATUS IN A HOME NETWORK SYSTEM - To solve the problems that may occur due to the leakage of user account information, the present disclosure may manage the security using the device token that is used independently of that of the server, that is generated by a home device, and that can be used for device authentication when a smart phone controls home appliances. With the use of the device token, the present disclosure may solve the problems that the status information of home appliances is exposed by another person or the home appliances are controlled by another person, even though the user account information is leaked. | 03-26-2015 |
