Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de réception de service de diffusion/multidiffusion (MBS), un procédé et un dispositif d'envoi de MBS, un terminal et une station de base. Ledit procédé de réception comprend les étapes consistant à : acquérir des informations de préconfiguration, un procédé de réception permettant de recevoir un MBS lorsqu'un terminal est dans un état de veille ou dans un état inactif étant défini dans les informations de préconfiguration ; et, lorsque le terminal est dans l'état de veille ou dans l'état inactif, recevoir le MBS selon le procédé de réception défini dans les informations de préconfiguration. Au moyen du procédé, des informations de préconfiguration sont délivrées à un terminal. Les informations de préconfiguration définissent un procédé de réception permettant de recevoir un MBS lorsque le terminal est dans un état de veille ou dans un état inactif, ce qui permet de résoudre le problème de l'art antérieur selon lequel un terminal dans un état de veille/inactif utilise un mécanisme de réception unifié pour la même cellule de desserte lorsqu'il reçoit un MBS et ne peut donc pas s'adapter à des conditions de service de cellule et à différentes exigences de retour de différents MBS.
