System and method for improving location estimates of co-located sectored cell sites for location services

摘要

Improved location estimates for transceivers is described. The location estimate of transceivers can be improved for sector transceivers that are co-located at a sectored cell site. The location estimate for each individual co-located sector transceiver can be updated as a centroid of all of the co-located sector transceivers. The location information of the transceivers can be used to provide network location estimation to mobile devices which do not have accurate positioning estimates.

1. A method of improving a location estimate of transceivers co-located at a sectored cell site, the method comprising:
identifying a plurality of transceivers that are co-located at the sectored cell site comprising:
accessing location information of a plurality of transceivers from a data store of a plurality of unique transceiver identifiers (IDs) and associated respective location estimates;grouping the plurality of transceiverlDs together into possible co-location groups based on the location estimates so that transceiverlDs associated with respective location estimates within a distance threshold of each other are grouped together; andfor each possible co-located group:
determining if the plurality of transceiverlDs of the plurality of transceivers in the possible co-located group are consistent with a co-location labelling format; andidentifying each of the plurality of transceiverlDs with consistent transceiver IDs as co-located transceivers; determining a location of a virtual transceiver as an average of respective location estimates of the plurality of identified transceivers; and assigning the determined location of the virtual transceiver to each of the transceivers determined to be co-located.
