摘要
The present invention relates to a method and apparatus for the efficient estimation of the movement state of a terminal in a mobile communication system. The method for the estimation of the movement state of a terminal in a mobile communication system according to one embodiment of the present invention comprises the following steps: receiving, from a base station, cell counting information to be used in counting for cell change; determining whether or not counting is restricted using the cell counting information during the cell change; if the counting is not restricted, counting the number of cell changes; and estimating the movement state of a terminal using the counted number of cell changes. According to the present invention, the movement state of a terminal can be efficiently estimated in a mobile communication system in which a plurality of cells having different sizes are arranged.
