A method and system for determining a position of a UE includes a first network node receiving a request for positioning information about the UE. The first network node requests a first positioning procedure at a first location node. The first location node determines using the first positioning procedure that involvement by a second location node is needed. The first location node initiates a trigger for positioning information about the UE to be sent to the second location node. The second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter, determines the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sends a position calculation response with the positioning information.

Method and apparatus for mobile positioning

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.

Wireless communication network for estimating the accuracy of fingerprinting positioning algorithms

A method for fingerprinting positioning decision support includes obtaining a geographic distribution probability of positions of measurement. A first collection of simulated measurements according to a signal model is generated, wherein each simulated measurement is associated with a respective pixel. The signal model is based on base stations located in the area. Fingerprinting positioning reference data is computed from the first collection and positions of the selected pixels. A second collection of simulated measurements is generated, which is statistically independent to the first collection. These simulated measurements are associated with a respective intended position within the area. Fingerprinting positioning is performed by the second collection utilizing the computed fingerprinting positioning reference data. An estimated accuracy of the fingerprinting positioning is calculated using a comparison between the intended position and the estimated position. This is made to evaluate positioning capabilities of fingerprinting positioning based on the measurement strategy.
