Abstract: Provided is a method of a multi-node cooperation considering a delay in a wireless communication system. A frame format may perform scheduling so that uplink cooperation terminals having a similar delay attribute may be classified into an uplink cooperation zone, to thereby prevent interference between the uplink cooperation zone and a non-cooperation zone. An extended cyclic prefix may be applied according to a delay attribute occurring due to an application of the multi-node cooperation. A cooperation base station of an uplink and a downlink may be determined based on the extended cyclic prefix.

Abstract: A method and apparatus establish a connection in a mobile terminal with a device compatible with BLUETOOTH, a short range wireless communications technology at the 2.4 GHz band. If connectable BLUETOOTH devices are detected in the vicinity of the mobile terminal and there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, the mobile terminal connects with a highest-priority BLUETOOTH device among the detected BLUETOOTH devices. If other connectable BLUETOOTH devices are detected in the vicinity of the mobile terminal while the mobile terminal is connected to a BLUETOOTH device, and there is at least one priority-registered BLUETOOTH device higher in priority than the currently connected BLUETOOTH device, among the detected BLUETOOTH devices, the mobile terminal switches the connection to a highest-priority BLUETOOTH device among the detected BLUETOOTH devices.

Abstract: A privacy protection policy is present in a content sharing system. A method for managing contents in a content sharing system includes receiving a content download request from a first account through a first device; and determining whether to carry out the download by considering at least one of a sharing range of a download-requested content, a content access right of the first account, a content access right of an owner account of the first device, a sharing range of a download folder, and sharing acceptance or rejection of an owner of the content.

Abstract: A method for determining a source and a transmission path to provide content includes receiving a message comprising at least one of channel information of a link between a request device which requests content download and a central management device, available resource amount information of a candidate device, channel information of a link between the candidate device and the central management device, and channel information of a link between the request device and one candidate device. The method also includes determining a source device and the transmission path for providing the content to the request device using an available resource amount of the candidate device, a data rate of the link between the request device and the central management device, a data rate of the link between the request device and the candidate device, and a data rate of the link between the candidate device and the central management device.

Abstract: A cloud service system includes at least one user device, a plurality of clouds for providing different cloud services, and a gateway connected between the user device and the clouds. The gateway selects at least one of the clouds according to predefined Service Level Agreement (SLA) information, and stores content provided from the user device to the selected cloud.

Abstract: A communication system and method for single-point transmission and reception and coordinated multi-point transmission and reception are provided. The system and method include determining information associated with a channel status of a target terminal. The system and method also include selecting, with respect to the target terminal, one of single-point transmission and reception and coordinated multi-point transmission and reception based on the information associated with the channel status of the target terminal.

Abstract: Provided are a method and system for handing over a mobile terminal between a macro base station and a vehicular base station to secure a communication service of a movable mobile terminal in a wireless communication system supporting a vehicular base station such as a vehicular relay station. The mobile terminal may be handed over by selecting a network or a vehicular base station suitable to a mobility and type of communication.

Abstract: Disclosed is a mobile terminal and method for managing a log during Bluetooth communication with a Bluetooth module in which information about a counterpart terminal connected via Bluetooth module is analyzed, the analyzed information about the counterpart terminal is stored, a task performed by the counterpart terminal is analyzed, the analyzed task is stored, and the stored information about the counterpart terminal and the task are displayed. The mobile terminal and method for managing a log enables a user of the mobile terminal to know what tasks were performed on a file of its mobile terminal by the counterpart terminal connected for Bluetooth communication. Since the mobile terminal can save original files using a backup function of log management, it is possible to prevent a serious problem caused by the counterpart terminal's arbitrary change or deletion of an important file in the slave unit.
