Paging messages are processed at the lower layer of the radio module level, not the application level. That is, the UE 60 that does not need to receive the CBS message does not receive the CBS message at the radio module level.

However, when determining whether or not to display the CBS message at the application level, the UE 60 needs to receive all the CBS messages even if they are unnecessary CBS messages. On the other hand, by determining whether or not a CBS message can be received at the radio module level, the UE 60 does not need to perform unnecessary CBS message reception processing.

Abstract

La présente invention a pour objet de réaliser un terminal de communications à l'aide duquel il est possible de limiter la consommation énergétique superflue associée à un processus de réception de messages de CBS qui se passe de réception. Un terminal (10) de communications selon la présente invention est muni d'une unité (11) de communications servant à recevoir un message de radiorecherche indiquant qu'un message de CBS a été distribué. En outre, le terminal (10) de communications est muni d'une unité (12) de commande de réception servant à décider s'il y a lieu ou non de recevoir le message de CBS distribué en utilisant des informations se rapportant au type du message de CBS, les informations étant spécifiées dans le message de radiorecherche.
