Abstract:
A remote management method for mobile devices is provided to enable a user to manage a mobile device more conveniently and easily in a remote place by using an OMA(Open Mobile Alliance) DM(Data Management) technique and DM silo standards. A user transmits a connection request message, including the identifier of a mobile device to be managed, to a DM server through a web client, one among the first through third control terminals(S300). Receiving the connection request message, the DM server requests a push proxy gateway to transmit a trigger message for the start of a DM session to the DM client of the mobile device corresponding to the identifier(S310). In case the mobile device receives the trigger message, the DM client of the mobile device executes a DM session connection with the DM server(S320). Then the DM client and the DM server execute authentication for each other(S330). The user transmits a management command associated with the DM client to the DM server through the web client(S340). Based on the management command, the DM server executes an associated management operation(S350).
Abstract:
A method for managing a file system and a device using the same are provided to make the different file systems or OSs(Operating System) compatible with each other, and realize a dynamic partition capable of efficiently using a physical storage device. The device includes the physical storage device(14), a metadata database(15), and the first and second unit. The first unit stores content data(11) to the physical storage device, and records i-node metadata to the metadata database. The i-node data is the data recording information corresponding to an i-node of the content data by using a generation language independent on the OS or the file system. The second unit records multimedia metadata recording the information related to multimedia contents by using the generation language to the metadata database. The i-node metadata includes the information for a physical address in a physical storage device, and a file type, size, and generation time.
Abstract:
PURPOSE: An electricity trade service method and system thereof are provided to enable a user to purchase power even in a separate place from charging station by performing electricity transaction between vehicles. CONSTITUTION: An electric power dealing service server(300) performs authentication based on the authentication information if electric power transaction request information including authentication information of a second vehicle form accepting the electric power and authentication information of a first vehicle for electric power supply. The electric power transaction service server transmits information permitting electric transaction to a first and a second vehicle charging terminals to the first and the second vehicles.
Abstract:
PURPOSE: A real time system for a vehicle and a method for measuring a worst response time are provided to more accurately measure the worst response time by analyzing the worst response time as a runnable unit which is more subdivided than task. CONSTITUTION: A method for measuring a worst response time using a real time system for a vehicle comprises; an input step of inputting data for operating a specific work; and a measurement step of measuring the worst response time in a minimum unit(240) for processing the inputted data. The minimum unit is a runnable unit. In the measurement step, the worst response time is measured using an operation time, a delay time, or a blocking time.
Abstract:
PURPOSE: A priority re-defining for saving scheduling time, a delay queue management method, and a system performing the method are provided to save scheduling time of the operating system and reduce memory resources of a system. CONSTITUTION: An initial priority in a priority area supported in an operating system is stored in a task. A priority for redefinition in the task is calculated using the initial priority. Priority allocated on the task based on the initial priority which is pre-defined by the operation system is re-defined(S101). The number of ready queues for performing the task according to the number of the re-defined priorities is determined(S102).
Abstract:
A method for providing a virtual personal computer environment and a mobile memory device therefor are provided to execute an OS that a user wants in an OS of a real PC. A storage module(210) stores a file system about one or more selectable guest OSs. A virtual PC module(220) executes a usage object guest that the user selects in the guest OS on a host OS of a PC by operating a virtual PC application. If the user connects a mobile memory device(200) to the PC, a connection module(230) of the mobile memory device transceives data with the PC through a predetermined communication protocol.

Abstract:
PURPOSE: A system and a method for using a bus lane are provided to inform a user of an estimated time when using the bus lane based on traffic conditions. CONSTITUTION: In a system and a method for using a bus lane, a terminal(110) is loaded in vehicles. The terminal generates bus lane information and sends it. A repeater station(130) relays the bus lane information. A server(150) receives the bus lane information and charge for using the bus lane.
