Abstract: Provided is an apparatus and method for transmitting/receiving time information in a mobile communication system. In a method for calculating a current time in the mobile communication system, time information is received from a base station. Date information and parameters for calculation of time are obtained on the basis of the received time information. A lapse time length from a reference time is calculated on the basis of the parameters. A current time is calculated using the calculated lapse time length and the date information. The time information is periodically transmitted and received using the idle frame of an idle state and the stealing flag of a normal burst contained in a BCCH.

Abstract: A stand for an image display device is provided. In the stand, a supporting member supports the image display device, a connecting member is rotatably coupled to the supporting member, and a base member supports the image display device with respect to a floor. The base member is rotatable in the same direction as the rotation direction of the connecting member for being folded to a back of the image display device. Therefore, a bottom surface of the stand can be folded to the back of the image display device, maximizing the number of image display devices that can be packed into the same containing space.

Abstract: A cell reselection function in a mobile station (MS) through an adjacent cell search is provided. The MS in an idle state obtains its own moving speed and current location using Global Positioning System (GPS) location information, calculates a predicted moving location, and stores the predicted moving location. Thereafter, when measurement values of adjacent cells are similar, or when the adjacent cells are located in different location areas (LAs), the MS can efficiently search for the best cell from among the adjacent cells based on the location information and select the best cell as a new serving cell.

Abstract: A logical channel establishment method for a mobile terminal is provided for improving network connection possibility and connection reliability. A logical channel establishment method of the present invention includes transmitting a resource request message for establishing a logical connection to an unlicensed wireless access network via a base station; retransmitting, when a resource request rejection message is received or no response message is received before a timer expires, the resource request message after a retry timer expires; and repeating retransmission of the resource request message a threshold number of retransmission times until a logical connection is established.

Abstract: An apparatus and method for performing a service registration through a cell reselection procedure in case of a service registration failure in a portable terminal are provided. The apparatus includes a service registration manager for acquiring cell reselection parameters of a cell to be reselected and a serving cell, and applying a cell reselection offset to the acquired cell reselection parameters of the serving cell to re-execute a cell reselection procedure; and a controller for directing the serving registration manager to change the cell reselection parameters of the serving cell to a cell reselectable condition to perform the cell reselection procedure when the service registration of the portable terminal fails.

Abstract: Provided are an apparatus and a method for scanning a Home Public Land Mobile Network (Home PLMN) in a mobile communication terminal that includes the operations of determining an operation mode of the mobile communication terminal, if a Home PLMN scanning timer expires, and setting a flag to indicate that the Home PLMN scanning timer expires, if the mobile communication terminal is determined to be in a non-idle mode. As a result, the Home PLMN can be searched as fast as possible.

Abstract: A method for controlling a transmission of Short Message Service (SMS) data during a handover of a mobile communication terminal and an apparatus thereof are provided. The method includes determining whether a handover is currently being conducted, if SMS transmission is requested in a communication mode; deferring the transmission of SMS data if it is determined that the handover is being conducted; and transmitting the SMS data if the handover is finished. Therefore, a call drop due to the transmission of SMS data during handover can be prevented, and the transmission of the SMS data is ensured.

Abstract: Disclosed is a cell selection method for providing better quality of service. For this purpose, when measurement values (for example, a receive level) from adjacent cells near a mobile station (MS) are similar to each other, the MS measures quality of a packet data traffic channel (PDTCH) through which data are transmitted. Then, based on the measured quality, the MS selects or reselects a new cell which can provide better QoS. Even when the receive levels of the adjacent cells near the MS are similar to each other, the MS can perform camping to the new cell which is capable of providing the best QoS so that the user of the MS may receive better QoS.
