PROCÉDÉ ET DISPOSITIF POUR LA PRÉSERVATION DE DONNÉES DE MOBILITÉ LORS D'UNE TRANSITION D'ÉTAT D'UN TERMINAL, ET POUR UN NOUVEL ACCÈS RÉUSSI DANS UN RÉSEAU CELLULAIRE HÉTÉROGÈNE DANS UN SYSTÈME DE COMMUNICATION MOBILE

摘要

The present invention pertains to a method and device for preserving mobility information in terminal state transition and effectively re-accessing in a heterogeneous cell network in a mobile communication system. A method for estimating a mobility state of a terminal in a mobile communication system according to one embodiment of the present invention may comprise the steps of: receiving, by the terminal, system information from a serving cell during an idle state; calculating mobility state information by using the received system information; storing the mobility state information; and transmitting the mobility state information to a base station when the terminal is connected to the base station. According to one embodiment of the present invention, when an idle state of a terminal is changed to a connection state in a mobile communication system, a mobility state of the terminal can be more effectively estimated.
