Le procédé comprend les étapes suivantes : lorsqu'une unité de gestion de mobilité connaît l'arrivée des données de liaison descendante, la source des données de liaison descendante est évaluée ; et lorsque les données de liaison descendante sont des données d'accès local, une recherche de personnes dans la zone d'accès local est réalisée. L'invention concerne également un appareil d'optimisation pour la recherche locale de personnes. L'appareil comprend une unité de réception de notification, une unité d'évaluation et une unité de commande de recherche de personnes. À l'aide du procédé et de l'appareil de l'invention, un réseau d'infrastructure peut déterminer les stations de base dans la zone de desserte d'une passerelle locale, et ainsi lorsque des données de liaison descendante d'accès local d'un utilisateur arrivent, la recherche de l'utilisateur dans la zone prenant en charge l'accès local de l'utilisateur est permise et la ressource de l'interface radio est sauvegardée.
