Abstract

L'invention concerne une station de base, un serveur, un dispositif et un procédé de détermination de localisation de cellule. Le procédé de détermination comprend les étapes suivantes : acquérir des informations d'historique d'un équipement utilisateur (UE), les informations d'historique comprenant : de l'UE, au moins des premières informations de localisation au niveau d'une première cellule et des deuxièmes informations de localisation au niveau d'une deuxième cellule, les premières et deuxièmes informations de localisation étant des éléments consécutifs d'informations de localisation ou comprenant au moins, de la manière rapportée par l'UE, des premières informations de mesure de puissance reçue de signal de référence (RSRP) de la première cellule et des deuxièmes informations de mesure de RSRP de la deuxième cellule, parmi lesquelles les premières et les deuxièmes informations de mesure de RSRP sont des éléments consécutifs des informations de mesure de RSRP et la première et la deuxième cellule étant des cellules adjacentes ; et déterminer, sur la base des informations d'historique de l'UE, que des troisièmes informations de localisation d'une troisième cellule doivent être ajoutées. La présente invention met en place une réduction des basculements fréquents entre deux cellules pour un utilisateur, ce qui améliore son expérience.
