Abstract
Presented are methods and apparatus for generating an inaccuracy characteristic for a fingerprinting positioning algorithm calculation associated with a user equipment location. Fingerprinting positioning measurements are compared to high-accuracy positioning measurements and an error value is determined. The error values are accumulated and the inaccuracy characteristic is generated based on an inaccuracy calculation. For areas where insufficient data is available, an inaccuracy characteristic value can be interpolated or extrapolated from adjacent areas containing sufficient data.
