Abstract: front page image
(EN)The embodiments of the present invention disclose a method and user terminal for receiving multicast control channel (MCCH) change notifications, which include: obtaining the transmission time of an MCCH change notification; and when the MCCH change notification is not received during one MCCH modification period, receiving, according to the transmission time of the MCCH change notification, the MCCH change notification at least N times, wherein N is the preset reception times of the MCCH change notification. In the present invention, the efficiency of receiving MCCH change notifications by user terminals is improved, and the probability of processing MCCH change notifications falsely due to too many network identifiers in a physical downlink control channel (PDCCH) is reduced.
(FR)La présente invention se rapporte, dans des modes de réalisation, à un procédé et à un terminal utilisateur permettant de recevoir des notifications de changement de canal de commande de multidiffusion (MCCH). Ledit procédé consiste à : obtenir le moment de transmission d'une notification de changement de canal MCCH ; et lorsque la notification de changement de canal MCCH n'est pas reçue pendant une période de modification de canal MCCH, recevoir, selon le moment de transmission de la notification de changement de canal MCCH, au moins N fois la notification de changement de canal MCCH, N étant les moments de réception prédéterminés de la notification de changement de canal MCCH. La présente invention permet d'améliorer l'efficacité de réception des notifications de changement de canal MCCH par des terminaux utilisateurs et de réduire la probabilité de traitement des notifications de changement de canal MCCH de manière erronée à cause d'identifiants de réseau trop nombreux dans un canal physique de commande de liaison descendante (PDCCH).
