Method and apparatus for the efficient estimation of the movement state of a terminal in a mobile communication system
First Claim
1. A method by a terminal in a wireless communication system, the method comprising:
- receiving cell counting information for use in counting cell switchings from a base station;
determining, in response to a cell switching occurring, whether to count the cell switching based on the cell counting information;
counting, when determined to count the cell switchings, in the cell switching for a number of the cell switchings; and
estimating a mobility state of the terminal based on the number of the counted cell switchings,wherein the cell counting information includes information indicating a cell switching type to be counted out, andwherein the cell switching type to be counted out comprises at least one of a cell switching to a frequency different from a serving frequency or a frequency having a priority different from the serving frequency, a cell switching related to a hybrid cell, or a cell switching for a multimedia broadcast multicast service (MBMS).

Abstract
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.
