Abstract

La présente invention appartient au domaine des télécommunications et concerne un procédé, un appareil, et un système d'acquisition d'informations système (SI). Le procédé consiste à : recevoir des informations d'indication envoyées par une station de base, les informations d'indication comprenant l'identificateur de premières autres SI, et les premières autres SI étant d'autres SI dans la station de base ; envoyer une demande de réception à la station de base lorsqu'il est déterminé que les informations d'indication indiquent que les premières autres SI sont mises à jour, la demande de réception contenant l'identificateur des premières autres SI ; et recevoir des informations de mise à jour envoyées par la station de base, les informations de mise à jour comprenant les premières autres SI mises à jour. La présente invention résout les problèmes liés, dans l'état de la technique, au manque d'efficacité d'un UE à recevoir des SI mises à jour, à la lourdeur d'une charge de signalisation, et à une augmentation du surdébit de signalisation du système occasionnée par le fait que l'UE doit relire toutes les SI. L'invention réduit ainsi la charge de signalisation et le surdébit de signalisation du système. La présente invention est utilisée pour acquérir des SI.
