The transmission of a warning message to a mobile terminal in a mobile communication network is triggered by an emergency event. The mo-bile terminal is first made aware of the need to receive a warning message by reception of an emergency event notification. The warning message is divided into a plurality of message segments. Each segment is transmitted in a separate paging message over a paging channel to mobile terminals in an idle mode. In-formation is added to each message segment to enable the mobile terminal to discriminate between segments belonging to different warning messages.
La transmission d'un message d'avertissement à un terminal mobile d'un réseau mobile de communication est déclenchée par un événement d'urgence. Le terminal mobile est d'abord averti de la nécessité de recevoir un message d'avertissement lors de la réception de la notification d'un événement d'urgence. Le message d'avertissement est divisé en plusieurs segments transmis dans un message de radiomessagerie séparé sur un canal correspondant à des terminaux mobiles en mode repos. Des informations sont ajoutées à chaque segment de message pour permettre au terminal mobile de distinguer les segments appartenant aux différents messages d'avertissement.
