Abstract

La présente invention se rapporte au domaine technique des communications, et porte sur un procédé et un appareil de mise à jour d'informations de cellule de desserte, destinés à être utilisés pour simplifier le processus de mise à jour d'informations de cellule de desserte. Le procédé comprend les étapes suivantes : un plan de commande d'unité centralisée (CU-CP) reçoit N éléments d'informations de cellule de desserte envoyés par une unité distribuée (DU), N étant un entier positif ; le CU-CP envoie ensuite les N éléments d'informations de cellule de desserte à un plan utilisateur d'unité centralisée (CU-UP) ; le CU-CP reçoit des informations d'indication envoyées par le CU-UP, les informations d'indication étant utilisées pour indiquer si un ou plusieurs éléments parmi les N éléments d'informations de cellule de desserte sont mis à jour avec succès. La présente invention est applicable au processus de déploiement d'une DU.
