Abstract: front page image
(EN)The present invention relates to a method and device for receiving a multimedia broadcast multicast service (MBMS) in a mobile communication system. The method for receiving the MBMS of a terminal in the mobile communication system according to an embodiment of the present invention is characterized in that it includes: determining whether service area ID (SAI) information on a serving cell is broadcast during the MBMS; receiving the SAI information on the serving cell when it is determined that the SAI information is broadcast; determining, by using the received SAI information of the serving cell, whether an SAI of the MBMS matches the SAI of the serving cell; and changing the cell reselection priority of the frequency of the serving cell to the highest priority if it is determined that the SAI of the MBMS matches the SAI of the serving cell. According to the present invention, it is possible to efficiently receive MBMS services by enabling a terminal to select a proper frequency or cell when an MBMS service of interest starts.
(FR)La présente invention concerne un procédé et un dispositif permettant de recevoir un service de diffusion/multidiffusion (MBMS) dans un système de communication mobile. Selon un mode de réalisation de la présente invention, le procédé permettant de recevoir le service MBMS d'un terminal dans le système de communication mobile consiste à déterminer si les informations ID de la zone de service (SAI) concernant une cellule de desserte sont diffusées pendant le MBMS, à recevoir les informations SAI concernant la cellule de desserte s'il est déterminé que les informations SAI sont diffusées, à déterminer, en utilisant les informations SAI concernant la cellule de desserte, si une SAI du MBMS correspond à la SAI de la cellule de desserte, et à modifier la priorité de nouvelle sélection de la fréquence de la cellule de desserte pour lui conférer la priorité la plus haute s'il est déterminé que la SAI du MBMS correspond à la SAI de la cellule de desserte. Selon la présente invention, il est possible de recevoir efficacement des services MBMS en permettant à un terminal de sélectionner une bonne fréquence ou une bonne cellule au démarrage du service MBMS concerné.
(KO)본 발명은 이동통신 시스템에서 멀티 미디어 방송 서비스(Multimedia Broadcast Multicast Service, MBMS)를 수신하는 방법 및 장치에 관한 것으로, 본 발명의 실시예에 따른 이동통신 시스템에서 단말의 멀티 미디어 방송 서비스(Multimedia Broadcast Multicast Service, MBMS) 수신 방법은, 상기 MBMS 진행 중, 서빙 셀의 SAI(Service Area ID) 정보가 방송되는지 여부를 판단하는 단계, 서빙 셀의 SAI(Service Area ID) 정보가 방송된다고 판단하는 경우, 상기 서빙 셀의 SAI(Service Area ID) 정보를 수신하는 단계, 상기 수신한 서빙 셀의 SAI(Service Area ID) 정보를 이용하여 상기 MBMS의 SAI와 상기 서빙 셀의 SAI가 매칭되는지 여부를 판단하는 단계 및 상기 MBMS의 SAI와 상기 서빙 셀의 SAI가 매칭된다고 판단하는 경우, 상기 서빙 셀의 주파수의 셀 재선택 우선 순위를 최우선(highest) 순위로 변경하는 단계를 포함하는 것을 특징으로 한다. 본 발명에 따르면, 관심을 가지고 있는 MBMS(Multimedia Broadcast Mulitcast Service) 서비스가 시작되는 시점에 맞춰 단말이 적절한 주파수 혹은 셀을 선택함으로써 MBMS 서비스를 효율적으로 수신할 수 있다.
