Title (EN) METHOD FOR DESIGNATING A DUAL REGION
(FR) PROCÉDÉ PERMETTANT DE DÉSIGNER UNE RÉGION DOUBLE
(KO) 듀얼 영역 지정 방법
Abstract:
(EN) A method for designating a dual region according to one embodiment of the present invention comprises the steps of: enabling a terminal which is in communication with a first network to calculate a channel state threshold value corresponding to data; comparing the channel state value of the first network and the channel state value of the second network, acquired using a pilot signal of a second network, with the channel state threshold value; calculating a network evaluation score of the first network; comparing the network evaluation score of the first network with a network evaluation threshold value for designating a dual region, if the channel state value of the first network and the channel state value of the second network are larger than the channel state threshold value; and determining whether to designate a dual region in accordance with the result of the comparison using the network evaluation threshold value. The method of the present invention can reduce service cutoff or delay time during inter-radio access.
(FR) La présente invention concerne un procédé permettant de désigner une région double, lequel procédé comprend les étapes qui consistent à permettre à un terminal qui est en communication avec un premier réseau de calculer une valeur seuil d'état de voie correspondant à des données; à comparer la valeur d'état de voie du premier réseau et la valeur d'état de voie du second réseau acquise au moyen d'une onde pilote d'un second réseau, avec la valeur seuil d'état de voie; à calculer un résultat d'évaluation de réseau du premier réseau; à comparer le résultat d'évaluation de réseau du premier réseau avec une valeur seuil d'évaluation de réseau afin de désigner une région double, si la valeur d'état de voie du premier réseau et la valeur d'état de voie du second réseau sont supérieures à la valeur seuil d'état de voie; puis à déterminer s'il convient de désigner une région double en fonction du résultat de la comparaison au moyen de la valeur seuil d'évaluation de réseau. Le procédé décrit dans la présente invention permet de réduire la coupure des services ou le retard pendant l'accès inter-radio.
(KO) 본 발명의 실시예에 따른 듀얼 영역 지정 방법은 제1 네트워크와 통신중인 단말이 데이터에 상응하는 채널 상태 임계값을 산출하는 단계, 상기 제1 네트워크의 채널 상태값 및 제2 네트워크의 파일럿 신호를 이용하여 획득한 상기 제2 네트워크의 채널 상태값을 상기 채널 상태 임계값과 각각 비교하는 단계, 상기 제1 네트워크의 네트워크 평가 점수를 산출하는 단계, 상기 제1 네트워크의 채널 상태값 및 제2 네트워크의 채널 상태값이 상기 채널 상태 임계값보다 큰 경우, 상기 제1 네트워크의 상기 네트워크 평가 점수를 듀얼 영역 지정을 위한 네트워크 평가 임계치와 비교하는 단계, 상기 네트워크 평가 임계치를 이용한 비교 결과에 따라 듀얼 영역 지정 여부를 결정하는 단계를 포함한다. 이기종망 연결 시 서비스의 끊김이나 지연 시간을 감소시킬 수 있다.
