Title (EN) ENHANCING OTDOA BSA ACCURACY USING UNSOLICITED RSTD MEASUREMENTS
(FR) AMÉLIORATION DE LA PRÉCISION D'UNE OTDOA BSA À L'AIDE DE MESURES RSTD NON SOLLICITÉES
Abstract: front page image
(EN)Techniques disclosed herein help a location server identify inaccuracies in a list of neighboring cells provided by the location server by enabling mobile devices during an OTDOA session to opportunistically take Reference Signal Time Difference (RSTD) measurements of additional cells not on the neighboring cell list (345, 350). The mobile device can then provide these RSTD measurements back to the server (365), which can optimize its algorithm for determining neighboring cells based on these measurements.
(FR)Les techniques décrites dans la présente invention aident un serveur de localisation à identifier des imprécisions dans une liste de cellules voisines fournies par le serveur de localisation en permettant à des dispositifs mobiles pendant une session OTDOA de prendre de manière opportuniste une différence de temps de signal de référence (RSTD) des mesures de cellules supplémentaires ne figurant pas sur la liste de cellules voisines (345, 350). Le dispositif mobile peut ensuite fournir ces mesures RSTD en retour au serveur (365), ce qui peut optimiser son algorithme de détermination des cellules voisines sur la base de ces mesures.
