20090025565 | AIR FILTERING DEVICE AND CLEANING SYSTEM OF SEMICONDUCTOR MANUFACTURING APPARATUS WITH THE SAME - An air filtering device and an air cleaning system of a semiconductor manufacturing apparatus to reduce cost and increase manufacturing productivity. The air filtering device may include a frame having an open aperture coupled to an air supply line. A buffer frame configured to be inserted into the frame may include a plurality of slot parts, each slot part having a plurality of air in/out apertures through which air may flow in or out from the buffer frame. A plurality of filters may be releasably fastened to the plurality of slot parts to filter pollution material contained in air flowing through the air in/out apertures. An air interrupter for interrupting air flowing through the air in/out apertures may be used when replacing the plurality of filters, thereby providing purified air to the semiconductor manufacturing apparatus during the replacement. | 01-29-2009 |
20130340040 | METHOD AND APPARATUS OF CONSTRUCTING SECURE INFRA-STRUCTURE FOR USING EMBEDDED UNIVERSAL INTEGRATED CIRCUIT CARD - Provided are a method and device for building a security-based environment that uses an eUICC. A method of building a trust relationship in an eUICC environment includes transmitting, by a trust requesting object, a trust relationship requesting message including identification information and signature information of the trust requesting object to a trust verifying object, delivering, by the trust verifying object, the trust relationship requesting message to a trust relationship relay object and receiving trust information of the trust requesting object corresponding to the trust relationship requesting message from the trust relationship relay object, and verifying, by the trust verifying object, the signature information of the trust requesting object using the trust information of the trust requesting object. | 12-19-2013 |
20130344864 | METHOD FOR PROVIDING SUBSCRIBER PROFILE OF eUICC - There is provided a method of providing a subscriber profile of an embedded universal circuit card (eUICC) that is performed in a terminal equipped with the eUICC. The method includes determining whether the terminal having a first subscriber profile stored therein has left a first mobile network operator (MNO) area corresponding the first subscriber profile, and when it is determined that the terminal has left the first mobile network operator area and moved into a second mobile network operator area, receiving a second subscriber profile corresponding to a second mobile network operator from a predetermined subscriber management server. In this way, it is possible to support mobile communication service by changing the mobile network operator even in the eUICC environment. | 12-26-2013 |
20140016547 | METHOD FOR CONNECTING WIRELESS CHANNEL AND APPARATUS FOR PERFORMING THE METHOD - The method performed in the terminal includes generating a random value for wireless channel access, receiving a competitive index indicating a channel competition state from an access point, and determining whether to attempt a wireless channel access based on a comparison result between the random value and the competitive index. | 01-16-2014 |
20140031012 | METHOD FOR PROVIDING SIM PROFILE IN EUICC ENVIRONMENT AND DEVICES THEREFOR - There are provided a method of providing a SIM profile, and an eUICC device. The method of providing the SIM profile includes downloading a SIM profile application selected by a user who uses the eUICC device from an app store, executing and installing the SIM profile application in the eUICC device, accessing of the eUICC device having the SIM profile application installed therein to an operator server, and authenticating the eUICC device based on SIM profile information corresponding to the SIM profile application. The eUICC device includes a network connection unit configured to access the app store via a local network, a SIM profile storage configured to store the SIM profile application, and an authentication requesting unit configured to access the operator server based on the SIM profile information. | 01-30-2014 |
20140045460 | METHOD AND APPARATUS OF PROVIDING SIM PROFILE FOR EMBEDDED UNIVERSAL INTEGRATED CIRCUIT CARD - There are provided a method of providing a SIM profile to an eUICC device online and a device using the same. The method of providing the SIM profile includes purchasing the SIM profile provided in an app store using a user device capable of accessing the app store, downloading the purchased SIM profile in the eUICC device using the eUICC device capable of accessing the app store, and installing the SIM profile, that is downloaded in the eUICC device, in the eUICC device therein. Therefore, it is possible to purchase the SIM profile using the online app store that is operated in a variety of forms and easily install the purchased SIM profile in the eUICC device. | 02-13-2014 |
20150087269 | METHOD FOR PROVIDING MOBILE COMMUNICATION PROVIDER INFORMATION AND DEVICE FOR PERFORMING SAME - A method of providing mobile communication provider information and a device for performing the same are disclosed. A terminal having an embedded universal integrated circuit card (eUICC) receives data in which the mobile communication provider information is encapsulated and stores the received data in the eUICC. Therefore, the mobile communication provider information may be transferred using the highest security scheme, and duplication of the eUICC due to the exposure of an authentication key by an external hacking attack may be prevented. | 03-26-2015 |
20150117424 | METHOD OF SCANNING ACCESS POINT - A method of scanning an access point is disclosed. The method of scanning the access point includes creating a probe request frame including information created based on an identifier of an access point to be searched, and transmitting the probe request frame. Thus, it is possible to decrease the time and power consumed by a terminal when searching an access point. | 04-30-2015 |
