CA 2666802

A position storage device includes: a storage unit (214) containing position information on a base station (30) performing radio communication with a radio terminal (40) which information is correlated to base station identifiers uniquely attached to the respective base stations; a reception unit which receives signal intensity information in which a signal intensity of a signal received from each base station by the radio terminal or information obtained from the signal intensity is correlated with the base station identifier of the base station which has transmitted the signal; a registration judging unit (222) which references the base station identifier registered in a storage unit and judges whether the base station identifier contained in the signal intensity information received by the reception unit is correlated with the position information in the storage unit; and a registration unit (226) which registers the base station identifier judged to be unregistered in the storage unit by the registration judging unit correlated with predetermined position information corresponding to the position of the radio terminal.

L'invention concerne un dispositif de stockage de position qui comprend : une unité de stockage (214) contenant des informations de position sur une station de base (30) effectuant une communication radio avec un terminal radio (40), lesquelles informations sont corrélées à des identifiants de station de base uniquement attachés aux stations de base respectives ; une unité de réception qui reçoit des informations d'intensité de signal, une intensité de signal d'un signal reçu à partir de chaque station de base par le terminal radio ou des informations obtenues à partir de l'intensité de signal, corrélées avec l'identifiant de station de base de la station de base qui a transmis le signal ; une unité (222) de détermination d'enregistrement qui référence l'identifiant de station de base enregistré dans une unité de stockage et qui détermine si non l'identifiant de station de base contenu dans les informations d'intensité de signal reçues par l'unité de réception sont corrélées ou non avec les informations de position dans l'unité de stockage ; et une unité d'enregistrement (226) qui enregistre l'identifiant de station de base déterminé comme n'étant pas enregistré dans l'unité de stockage par l'unité de détermination d'enregistrement, corrélé aux informations de position prédéterminées correspondant à la position du terminal radio.
