Abstract: Disclosed herein is an integrated connection apparatus for the receivers of a car. The integrated connection apparatus for the receivers of a car, in which two or more receivers are installed in the car, a number of antennas equal to the number of the receivers are installed, and the receivers and the antennas are electrically connected to each other, includes an antenna filtering unit connected to the plurality of antennas and configured to filter radio wave signals, received through the respective antennas, for respective frequency bands, an integrated cable connected to the filtering unit, and configured to provide a path for collecting signals obtained through filtering and transmitting the signals to a receiver side, and a receiver filtering unit connected to the integrated cable, and configured to classify the signals, transmitted through the integrated cable, into signals suitable for the respective receivers and transmit them.

Abstract: Disclosed herein is a hands-free cellular phone device for vehicles. The device consists of a casing provided with a speaker, a mike, several control buttons including a call button, and jacks. In addition, the device has a structure capable of transceiving sound through the speaker and the mike in a call mode without holding a cellular phone with a user's hand when a power source and the cellular phone are connected to the associated jacks. In this case, a mounting hole is formed on the casing such that the casing is locked to a hand grip fitting hole by a bolt. The bolt passes through the mounting hole and is tightened into the hand grip fitting hole. The hand grip fitting hole is formed on the inside wall of a vehicle body above a side window adjacent to a driver's seat.

Abstract: A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
