Network centric localization for determining the location of mobile devices
First Claim
1. A system comprising:
- a location server comprising a network interface for receiving a plurality of measurement reports submitted from a plurality of reference nodes of a location network, each of the plurality of measurement reports reporting a measurement of a signal received by a respective one of the plurality of reference nodes from a respective one of one or more mobile devices;
a localization module configured to determine a location of the one or more of the mobile devices based on at least some of said plurality of measurement reports; and
a node manager configured to control whether and/or when one or more of said plurality of measurement reports are submitted from one or more of the plurality of reference nodes, in dependence on a measure of relevance to said determination of the location of the one or more of the mobile devices;
wherein said control by the node manager comprises;
controlling a time at which one or more of the measurement reports are submitted to the location server, the time depending on the measure of relevance so as to be staggered in time relative to the submission of one or more others of the measurement reports, andwherein controlling said time comprises;
delaying the time at which one or more of the measurement reports are submitted, the delay being inversely related to the measure of relevance.

Abstract
A system comprising location server, a localization module and a node manager. The location server comprises a network interface operable to receive measurement reports submitted from a plurality of reference nodes of a location network, each measurement report reporting a measurement of a signal received by a respective one of the reference nodes from a respective one of one or more mobile devices. The localization module is configured to determine a location of one or more of the mobile devices based on at least some of the plurality of measurement reports. The node manager is configured to control whether and/or when one or more of the plurality of measurement reports are submitted from one or more of the reference nodes, in dependence on a measure of relevance to the determination of the location of one or more of the mobile devices.

12. A computer program product for use in relation to a location network where a plurality of measurement reports can be submitted from a plurality of reference nodes to a location server, each of the plurality of measurement reports reporting a measurement of a signal received by one of the plurality of reference nodes from one of one or more mobile devices, and where the location server determines a location of the one or more of the mobile devices based on at least some of said plurality of measurement reports;
-
wherein the computer program product comprises code embodied on a non-transitory computer readable storage medium and configured so as when executed on the location server or one or more of the reference nodes to perform operations of;
controlling whether and/or when one or more of said plurality of measurement reports are submitted from one or more of the plurality of reference nodes, in dependence on a measure of relevance to said determination of the location of one or more of the mobile devices,wherein said control comprises;
controlling a time at which one or more of the measurement reports are submitted to the location server, the time depending on the measure of relevance so as to be staggered in time relative to the submission of one or more others of the measurement reports, andwherein controlling said time comprises;
delaying the time at which one or more of the measurement reports are submitted, the delay being inversely related to the measure of relevance.

13. One of a plurality of reference nodes for use in a location network where a plurality of measurement reports can be submitted from the plurality of reference nodes to a location server, each of the plurality of measurement reports reporting a measurement of a signal received by one of the plurality of reference nodes from one of one or more mobile devices, and where the location server determines a location of one or more of the mobile devices based on at least some of said plurality of measurement reports;
-
wherein said one of the reference nodes comprises a node manager configured to control whether and/or when one or more of the plurality of measurement reports are submitted from said one of the reference nodes, in dependence on a measure of relevance to said determination of the location of one or more of the mobile devices, wherein said control by the node manager comprises;
controlling a time at which one or more of the measurement reports are submitted to the location server, the time depending on the measure of relevance so as to be staggered in time relative to the submission of one or more others of the measurement reports, andwherein controlling said time comprises;
delaying the time at which one or more of the measurement reports are submitted, the delay being inversely related to the measure of relevance.
