Abstract

La présente divulgation concerne un procédé et un appareil pour transmettre un message de radiomessagerie, et un support de stockage lisible. Le procédé consiste à : envoyer une indication de radiomessagerie à un équipement utilisateur (UE) à distance, l'indication de radiomessagerie étant utilisée pour indiquer un message de radiomessagerie envoyé par un dispositif de réseau à l'UE distant ; et envoyer une indication de rétroaction au dispositif de réseau sur la base du fait que l'indication de radiomessagerie est envoyée ou non à un UE distant correspondant, l'indication de rétroaction étant utilisée pour indiquer si le message de radiomessagerie est envoyé avec succès. Dans des modes de réalisation de la présente divulgation, après qu'un UE de relais envoie l'indication de radiomessagerie à l'UE distant, l'indication de rétroaction peut être envoyée au dispositif de réseau selon la condition de transfert, de sorte que le dispositif de réseau puisse savoir si le message de radiomessagerie est envoyé avec succès ou non à temps. Lorsque le message de radiomessagerie ne parvient pas à être envoyé, le dispositif de réseau peut retransmettre le message de radiomessagerie à temps, garantissant ainsi que le message de radiomessagerie est envoyé avec succès à l'UE distant sans être perdu.
