Abstract

La présente invention concerne un procédé et un système de configuration d'informations publiques de cellule, le procédé comportant les étapes suivantes : un élément de réseau d'accès radio envoie des informations publiques de cellule à une partie ou à la totalité des terminaux mobiles résidant dans la cellule par l'intermédiaire de messages de radiorecherche et indique des informations de paramètres d'efficacité des informations publiques de cellule à ladite partie ou totalité des terminaux mobiles ; ladite partie ou totalité des terminaux mobiles reçoit les informations publiques de cellule et utilise les informations publiques de cellule en fonction desdites informations de paramètres d'efficacité. La présente invention permet à l'élément de réseau d'accès de configurer dynamiquement des informations publiques de commande de la cellule ou une configuration publique de canaux selon les exigences de service, ce qui a pour effet de satisfaire les exigences de service en temps utile et d'améliorer le rendement d'utilisation des ressources radio.
