摘要： The present invention defines an efficient method for (re)selecting a cell according to a speed of a terminal in a HetNet where cells having various regions such as macro cells, pico cells and femto cells are arranged in the same frequency band in a mobile communication system. A cell selection control method of a terminal in a mobile communication system, according to an embodiment of the present invention, comprises a step of receiving, from a base station, cell list information for not allowing a terminal moving at a high speed to select a cell and a step of setting the terminal so that cells included in the cell list information are considered or not considered to be targets of selection or reselection when the terminal moves at the high speed. According to the present invention, in a network consisting of various types of cells using the same frequency band, the terminal can determine whether to select or reselect a cell according to the speed of the terminal. That is, the terminal moving at the high speed does not select or reselect a frequent service cell, thereby efficiently performing the cell selection or reselection. Further, power consumption of the terminal can be reduced.

摘要： A method and apparatus is configured to control a discontinuous reception (DRX) in a mobile communication system. The method includes: interrupting the DRX operation when a radio resource control (RRC) connection reestablishment procedure is initiated; transmitting an RRC connection reestablishment request message from the user equipment to an evolved node B (ENB); receiving an RRC connection reestablishment message from the ENB to the user equipment; and resuming, if the received RRC connection reestablishment message contains new DRX setting information, the interrupted DRX operation according to the new DRX setting information. The DRX operation can be interrupted or resumed at a proper time point when an RRC connection is reestablished or reconfigured or a handover is performed, thereby reducing power consumption in the user equipment.

摘要： An Automatic Repeat reQuest (ARQ) method in a communication system having a protocol layer structure, in which a Layer 2 (L2) transmitter for generating an upper layer packet in a size suitable for transmission over a radio channel and transmitting the upper layer packet to a lower layer, transmits, to a receiver, polling information representative of an indicator for ordering the generation of a status report, and performs packet ARQ according to whether the status report is received within a predetermined time. The method includes determining whether there is a possibility that upper layer data contained in a packet data unit to be transmitted along with the polling information will cause an upper layer message in the opposite direction; and when there is a possibility that the upper layer data will cause an upper layer message, generating polling information ordering a receiver to wait for a predetermined time after receipt of a packet and to transmit an upper layer packet generated for the waiting time along with a status report, including the polling information in the packet data unit, and delivering the packet data unit to the lower layer.

摘要： A call setup method and apparatus for minimizing call setup delay by a UE in a mobile telecommunications system are provided. The method includes the steps of: if call setup for a packet call service is requested, determining by the UE if the requested service is a predetermined service sensitive to call setup delay; if the requested packet call service is the predetermined service sensitive to the call setup delay, establishing control information representing that the packet call service is sensitive to the call setup delay; and transmitting a request message requesting the call setup to a network, the request message including the control information. In the method, a network causes a UE using a packet call service sensitive to call setup delay to maintain a connected state, so that restart delay of the packet call service can be minimized.
