Abstract: A method and system for an emergency call service in an unlicensed mobile access (UMA) network are disclosed. The emergency call service method includes: receiving, by a mobile terminal on an unlicensed network, an emergency call; forwarding, by the unlicensed network, the emergency call and an AP (access point) list related to an AP associated with the mobile terminal to a core network; searching for, by the core network, location information of the mobile terminal corresponding to the AP list; and sending, by the core network, an emergency report containing the location information of the mobile terminal to a safety manager.

Abstract: Provided is an apparatus and method for idle state current saving in a mobile communication terminal. The method includes checking whether a BTS search event is generated when accessing a UMAN and being in an idle state, searching neighbor BTS information, checking whether a rove-out event is generated, identifying an AP list and checking whether there is previous rove-out BTS information, checking whether it is possible to rove out to a BTS associated with the stored BTS information, and roving out to the BTS.

Abstract: Provided are a method and apparatus for avoiding interference during a call in a portable terminal that supports Unlicensed Mobile Access (UMA). The method includes measuring a Carrier to Interference and Noise Ratio (CINR) of a channel in which a call is established, and comparing the CINR with a predetermined first threshold; if the CINR of the channel is greater than the first threshold, searching for a peripheral channel and measuring a CINR of the peripheral channel; comparing the CINR of the peripheral channel with a predetermined second threshold; and if the CINR of the peripheral channel is less than the second threshold, determining that is a handover to be performed to the peripheral channel.

Abstract: A portable terminal having a tuner for changing an antenna radiation pattern is disclosed. In the portable terminal, a main body has a main body PCB and a main body ground defined in the main body PCB. A folder is rotatably connected to the main body by a hinge device. An antenna device is provided at an upper end of the main body. The tuner is formed at a predetermined position of the main body in the vicinity of the antenna device, for changing a current distribution of the main body and thus changing an antenna radiation pattern of the portable terminal.

Abstract: A sliding/swing-type portable digital communication apparatus including a main housing having a speaker unit positioned on its rear surface; key housings, each of which is positioned on a side of the main housing, the key housings being adapted to slide a predetermined distance toward or away from the main housing along a longitudinal direction for exposing or hiding the speaker unit according to whether or not the key housings have slid; and a swing housing adapted to rotate about a hinge axis, which is oriented perpendicular to the sliding direction of the key housings, within a predetermined range of angle while continuously facing an upper surface of the main housing and upper surfaces of the key housings for exposing and hiding predetermined areas of the key housings.

Abstract: The present invention relates to a device and method for improving a radiation pattern of a built-in antenna in a folder-typed mobile wireless terminal that has a main body having the RF board installed with a built-in antenna, a sub-body to be opened and closed at an angle from the main body, and a hinge module configured to open and close the sub-body. The device includes a conductive ground means installed in the sub-body at a portion adjacent to the built-in antenna, for minimizing a radiation pattern difference of the built-in antenna between the opening and closing of the sub-body, thereby increasing reliability of the terminal.

Abstract: Disclosed is a sliding-type portable wireless terminal capable of easily opening and closing a sub-body in a lengthwise manner and a method for controlling a sliding movement thereof. The sliding type portable wireless terminal includes a main body and a sub-body movable from an open position to a closed position with respect to the main body by slidably moving in a lengthwise direction with respect to the main body. The sliding type portable wireless terminal has a first gear installed on an upper portion of the main body, a second gear provided at a rear portion of the sub-body in such a manner that the second gear is engaged with the first gear, with a motor connected to the first gear so as to provide rotational force to rotate the first gear, and a control unit for controlling an operation of the motor in response to a predetermined key input signal by a user for controlling a sliding movement of the sub-body.
