Abstract
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.
Claims20
A method of improving a location estimate of transceivers, the method comprising:
- identifying a plurality of transceivers co-located at a sectored cell site each having respective location estimates as a co-located group;
- determining a location of a virtual transceiver for the co-located group by using an average of the respective location estimates of each of the plurality of identified transceivers;
- and
- assigning the determined location of the virtual transceiver to each of the transceivers of the co-located group at the sectored cell site.
An apparatus for estimating a transceiver's location comprising:
- at least one processing unit for executing instructions;
- and
- at least one memory unit for storing instructions, the instructions when executed by the at least one processing unit configuring the apparatus to:
- identify a plurality of transceivers co-located at a sectored cell site each having respective location estimates as a co-located group;
- determine a location of a virtual transceiver for the co-located group by using an average of the respective location estimates of each of the plurality of identified transceivers;
- and
- assign the determined location of the virtual transceiver to each of the transceivers of the co-located group at the sectored cell site.
A non-transitory computer readable memory storing computer executable instructions thereon that when executed by a processor perform:
- identifying a plurality of transceivers co-located at a sectored cell site each having respective location estimates as a co-located group;
- determining a location of a virtual transceiver for the co-located group by using an average of the respective location estimates of each of the plurality of identified transceivers;
- and
- assigning the determined location of the virtual transceiver to each of the transceivers of the co-located group at the sectored cell site.
