Abstract

La présente invention se rapporte à un procédé de traitement de données de position. Le procédé selon l'invention comprend l'étape suivante : quand un terminal enregistre une position, un serveur de positions établit une relation de mappage entre les données d'identification et de connexion d'un terminal et des données de position du terminal. La présente invention se rapporte d'autre part à un serveur de positions. Le serveur de positions selon l'invention est configuré de façon à, quand un terminal enregistre une position, établir une relation de mappage entre les données d'identification et de connexion d'un terminal et des données de position du terminal. La présente invention se rapporte par ailleurs à un système de traitement de données de position. La solution technique de la présente invention permet de résoudre le problème lié au fait qu'une extrémité opposée ne peut pas acquérir de données de position précises d'un terminal dans un scénario comprenant une pluralité d'éléments de données de position. En conséquence, l'expérience d'utilisation d'un utilisateur se trouve significativement améliorée.
