Mobile communication terminal enable to re-select of cell and its operating method

Abstract

A mobile communication capable of re-selecting a cell in accordance with a residual amount of a battery so that the number of times of re-selecting a cell is reduced in accordance with the residual amount of the battery is provided. Information on a plurality of cells having different priorities in a hierarchical cell structure (HCS) is received and a cell measuring reference is re-set in accordance with the received cell information or the residual amount of the battery so that the mobile communication terminal is connected to a cell selected among the cells measured in accordance with the re-set measuring reference. A cell is re-selected in accordance with information received from the connected cell or cells adjacent to the connected cell and a cell measuring reference is re-set so that cells of low priorities are measured in accordance with the residual amount of the battery. Therefore, it is possible to reduce the number of times of re-selecting a cell and to thus reduce the residual amount of the battery.

Description

technical field [0001] The present invention relates to a mobile communication terminal capable of reselecting a cell according to the remaining battery level and an operation method thereof, in particular to a mobile communication terminal capable of reselecting a cell according to the remaining battery level, thereby reselecting a cell measurement reference reference according to the remaining battery level, so as to reduce the A mobile communication terminal and an operating method thereof for reselecting the number of times a cell is changed. Background technique [0002] Generally speaking, during the change of location in a cell, the mobile communication terminal generates an internal trigger according to the received signal strength and data transmission rate of the connected cell, and whether the location changes in the cell. Select a new cell between the cells. [0003] At this time, as shown in FIG. 1, during the change of the position of the current connected cel...
