CA 2386681

A method and apparatus for assigning location estimates from a first transceiver of a plurality of wireless transceivers to a second transceiver is disclosed. The present invention makes use of a low power short-range auxiliary communication link incorporated within networked devices to interact with nearby devices for obtaining location estimates of the current location of a device. Confidence levels are then assigned to the information obtained from the interactions with the nearby devices, and a determination of whether to update the location estimate is made.

L'invention concerne un procédé et un appareil de transfert d'estimations de localisation d'un premier émetteur-récepteur (122) d'une pluralité d'émetteurs-récepteurs (122) sans fil vers un second émetteur-récepteur (132). La présente invention utilise une liaison de communication auxiliaire à faible portée et basse puissance incorporée à des dispositifs en réseau pour interagir avec les dispositifs proches afin d'obtenir des estimations de localisation de l'emplacement courant d'un dispositif. Les estimations (504) de confiance sont alors affectées aux informations obtenues à partir des interactions avec les dispositifs proches, et une détermination (508) d'actualisation ou de non actualisation de l'estimation de localisation est effectuée.
