Abstract

La présente invention se rapporte à un procédé, à un équipement d'utilisateur et à un dispositif de réseau adaptés pour rechercher un micro site. Le procédé selon l'invention consiste : à acquérir des premières données de position d'un micro site par rapport à trois sites de référence ou plus, et à acquérir d'autre part des données de site de référence des trois sites de référence ou plus (S110) ; sur la base des données de site de référence, à déterminer des secondes données de position d'un équipement d'utilisateur par rapport aux trois sites de référence ou plus (S120) ; et, sur la base des premières données de position et des secondes données de position, à déterminer la relation de position de l'équipement d'utilisateur par rapport au micro site (S130). La présente invention est apte à déterminer la relation de position d'un équipement d'utilisateur par rapport à un micro site sur la base des données de position respectives du micro site et de l'équipement d'utilisateur par rapport à des sites de référence. Cela permet à l'équipement d'utilisateur de rechercher le micro site uniquement quand il est proche du micro site. Par voie de conséquence, cela permet de réduire la consommation d'électricité de l'équipement d'utilisateur et d'améliorer l'expérience de l'utilisateur.
