Abstract

L'invention concerne un procédé, un dispositif et un système de diffusion et d'acquisition d'informations d'identification de zone de localisation (LAI), ledit procédé inclut les opérations suivantes : si une entité de plan de commande (CPE) détermine que les informations LAI diffusées sont les premières informations LAI, alors envoyer un message avec des informations d'identification spéciales à un UE en fonction des premières informations LAI ; l'UE acquiert les premières informations LAI correspondantes en fonction des informations d'identification spéciales après avoir reçu le message contenant les informations d'identification spéciales. La CPE ci-dessus envoie les informations d'identification spéciales à l'UE au lieu d'envoyer les informations LAI de manière répétée si elle détermine que les informations LAI diffusées à l'UE sont les mêmes que celles diffusées antérieurement. Elle n'impose évite ainsi d'imposer une charge inutile au réseau, en particulier si la CPE diffuse les informations LAI en excès, et elle économise des ressources d'interface radioélectrique.
