Title (EN) HANDOVER METHOD
(FR) PROCÉDÉ DE TRANSFERT
(KO) 핸드오버 방법
Abstract:
(EN) A handover method according to one embodiment of the present invention comprises the steps of receiving the result of a cell measurement for a neighbor cell from a terminal, judging whether the neighbor cell is a near neighbor cell in accordance with the result of the cell measurement, calculating the ratio of the near neighbor cell to the total neighbor cells, and transmitting a command for a handover to a target cell to the terminal if the ratio exceeds the handover threshold value. The handover method of the present invention reduces interference between cells, and efficiently uses radio resources.
(FR) Selon un mode de réalisation de la présente invention, un procédé de transfert comprend les étapes suivantes : réception du résultat d'une mesure de valeur de cellule concernant une cellule voisine d'un terminal; évaluation de si la cellule voisine est une cellule voisine proche en fonction du résultat de la mesure de valeur de cellule; calcul du rapport de la valeur de cellule voisine proche sur les valeurs de toutes les cellules voisines; et transmission au terminal d'une commande visant à effectuer un transfert vers une cellule cible, si le rapport dépasse une valeur seuil de transfert. Le procédé de transfert de l'invention permet la réduction des interférences entre les cellules et un emploi efficace des ressources radio.
(KO) 본 발명의 실시예에 따른 핸드오버 방법은 단말로부터 이웃셀에 대한 셀 측정 결과를 수신하는 단계, 상기 셀 측정 결과에 따라 상기 이웃셀이 가까운 이웃셀인지 판단하는 단계, 전체 이웃셀 중에서 가까운 이웃셀의 비율을 산출하는 단계, 상기 비율이 핸드오버 임계치를 초과하는 경우, 상기 단말에게 타겟셀로의 핸드오버 명령을 전송하는 단계를 포함한다. 셀 간 간섭 현상을 줄이고, 무선자원을 효율적으로 사용할 수 있다.
