L'invention concerne le domaine des communications et décrit un procédé et un dispositif pour localiser un HeNB afin de maîtriser précisément les informations de localisation au sujet du HeNB. Le procédé comprend les étapes suivantes : un HeNB envoie un message de demande de localisation à un E-SMLC par l'intermédiaire d'une interface S1, l'E-SMLC charge l'HeNB de réaliser une mesure de localisation et localise l'HeNB selon le résultat de mesure de localisation renvoyé par l'HeNB afin d'obtenir les informations de localisation au sujet du HeNB, et l'HeNB reçoit un message de réponse de localisation de l'E-SMLC par l'intermédiaire de l'interface S1 et détermine la localisation physique du HeNB selon les informations de localisation portées dans le message de réponse de localisation ; de cette manière, le flux d'interaction entre l'HeNB et l'E-SMLC est redéfini en fonction du protocole d'interface S1 et du LPP, de sorte que l'HeNB peut être localisé précisément, et une gestion efficace peut être réalisée dans l'hypothèse de maîtrise de la situation de distribution spécifique du HeNB de manière opportune, garantissant ainsi les performances du système.
