Abstract
Systems and methods for estimating the minimum geographic coverage of a wireless base station. In an embodiment, the present invention estimates coverage by (1) receiving real-time wireless base station information from the mobile device; (2) extracting a set of location points and system specific information based on the real-time wireless base station information; (3) determining a coverage area based on the set of location points and the system specific information; (4) adjusting for errors based on various factors (5) storing the determined coverage area.
Claims16
An apparatus for determining a minimum coverage area of a wireless base station, the apparatus comprising:
- a coverage area metrics determiner configured to determine at least two coverage area metrics based on received data samples and a determined centroid, such centroid corresponding to an estimate of the location of the wireless base station;
- a metrics weight determiner configured to:
- determine a respective weight for each determined coverage area metric, and
- adjust one or more determined respective weights based on a ratio of a characteristic of the received data samples and a characteristic of a plurality of wireless base stations in a geographical area from which the received data samples were received;
- a weighted coverage estimator configured to estimate a minimum geographic coverage area for the wireless base station based on the coverage area metrics and the respective weight associated with each determined coverage area metric;
- and
- a storage device configured to store the estimated minimum coverage area.
A method of determining, with a processor, the minimum geographic coverage area for a wireless base station, the method comprising:
- receiving at least one data sample from a mobile device;
- receiving a derived centroid from a centroid determiner, such centroid corresponding to an estimate of the location of the wireless base station;
- determining, using the processor, at least two coverage area metrics based on the received at least one data sample;
- determining a respective weight for each determined coverage area metric;
- adjusting one or more determined respective weights based on a ratio of a characteristic of the received at least one data sample and a characteristic of a plurality of wireless base stations in a geographical area from which the received at least one data sample was received;
- estimating, using the processor, a minimum geographic coverage area for the wireless base station based on the coverage area metrics and the respective weight associated with each determined coverage area metric;
- and
- storing the estimated minimum geographic coverage area to a storage device.
A non-transitory computer-readable medium having computer-readable instructions encoded thereon that, when executed by a processor cause the processor to perform a method of determining the minimum geographic coverage area for a wireless base station, the method comprising:
- receiving at least one data sample from at least one mobile device;
- receiving a derived centroid from a centroid determiner, such centroid corresponding to an estimate of the location of the wireless base station;
- determining, using the processor, at least two coverage area metrics based on the received at least one data sample;
- determining a respective weight for each determined coverage area metric;
- adjusting one or more determined respective weights based on a ratio of a characteristic of the received at least one data sample and a characteristic of a plurality of wireless base stations in a geographical area from which the received at least one data sample was received;
- estimating, using the processor, a minimum geographic coverage area for the wireless base station based on the coverage area metrics and the respective weight associated with each determined coverage area metric;
- and
- storing the estimated minimum geographic coverage area to a storage device.
