Abstract
Method and apparatus are provided for localizing wireless devices. In one such arrangement, a method of fingerprinting includes receiving, by a first network element, a plurality of records from a second network element and determining a first segment. A first drive test record of the plurality of records can be assigned to the first segment, and a second segment can be determined, where a first area of the first segment is not equal to a second area of the second segment. A second drive test record of the plurality of records can be assigned to the second segment.
Claims28
A method of localizing wireless devices, the method comprising:
- receiving, by a first network element, a plurality of records from a second network element;
- determining a first segment;
- assigning a first drive test record of the plurality of records to the first segment;
- determining a second segment, wherein a first area of the first segment is not equal to a second area of the second segment;
- and
- assigning a second drive test record of the plurality of records to the second segment.
A method for constructing a density map of wireless device density, the method comprising:
- receiving, by a network element, a plurality of measurement reports;
- obtaining a plurality of fingerprints;
- calculating a plurality of distances between a first measurement report of the plurality of measurement reports and the plurality of fingerprints, wherein a minimum distance of the plurality of distances is a first distance between the first measurement report and a first fingerprint of the plurality of fingerprints, and wherein a second smallest distance of the plurality of distances is a second distance between the first measurement report and a second fingerprint of the plurality of fingerprints;
- allocating a first fraction of the first measurement report to a first segment corresponding to the first fingerprint;
- and
- allocating a second fraction of the first measurement report to a second segment corresponding to the second fingerprint.
A method for selecting data for wireless device localization, the method comprising:
- receiving, by a network element, a plurality of records;
- determining if a first drive test record of the plurality of records is information rich;
- and
- adjusting the first drive test record of the plurality of records when the first drive test record is not information rich.
A system for localizing wireless devices, the system comprising:
- a processor;
- and
- a computer readable storage medium storing programming for execution by the processor, the programming including instructions to
- receive a plurality of records from a node,
- determine a first segment,
- assign a first drive test record of the plurality of records to the first segment,
- determine a second segment, wherein a first area of the first segment is not equal to a second area of the second segment, and
- assign a second drive test record of the plurality of records to the second segment.
