  • Patent number: 9952994
    Abstract: An integrated multimedia system and a control method are provided, in which, when a USB port is reset during a misrecognition and malfunction of a USB connected to a port of an integrated multimedia terminal integrally provided with an SD slot, an SD slot is prevented from being reset to improve the stability and quality of an AVN system. The system includes an integrated multimedia terminal including a USB port for electrical connection of a USB and an SD slot for electrical connection of an SD card. An audio video navigation (AVN) controller detects the SD card and the USB, obtains data of the SD card and the USB and is connected to the integrated multimedia terminal. A hub electrically connects the SD slot and the USB port to the AVN controller and an auxiliary controller operates the USB port in response to a control signal transmitted via the hub.

  • Patent number: 9930701
    Abstract: A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

  • Publication number: 20180084530
    Abstract: In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.

  • Publication number: 20180049124
    Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is received.
