Claim:
1. A method for traffic density estimation and user localization, the method comprising: sending, from a network component, a request to a plurality of user equipment (UEs) to participate in reporting training data, the training data including location and/or fingerprint data; receiving, from at least a portion of the plurality of UEs, a plurality of reports for training data including no-satellite-lock reports and the training data from the at least the portion of the plurality of UEs, wherein the no-satellite-lock reports indicate indoor UEs among the at least the portion of the plurality of UEs; discarding at least some of the training data that includes a noise level higher than a pre-determined threshold; associating, by the network component, the indoor UEs with corresponding buildings in a service area of the network component in accordance with the training data and the no-satellite-lock report to produce building associations; building a radio map in accordance with the training data and the no-satellite-lock report to produce a non-uniform bin grid; and using a soft decision approach for performing traffic density estimation, without performing hard localization, in accordance with the radio map, the non-uniform bin grid, and the building associations.
