Claim:
1. A method for dynamically altering a signal-space-to-physical-space mapping database of a set of access points for use in localizing of an object, comprising: obtaining a location profile for the object, the location profile comprising an object's location pattern and an object's location behaviour, and corresponding with a set of probabilities where an object to be tracked is positioned at a certain position during a given time interval, wherein the location behaviour of the object to be tracked is based on different behaviours during a given day or during a given week, obtaining an estimated location of the object by measuring a signal parameter induced by at least one access point and using the signal-space-to-physical-space mapping database to derive an estimated location from the measured signal parameter, determining whether the obtained estimated location complies with the obtained location profile including the location behaviour for the object by determining whether or not the object is, within a predetermined time interval, located at a location different from a location based on the location profile including the location behaviour, and if the obtained estimated location does not comply with the location profile including the location behaviour, dynamically adjusting the mapping database to obtain an adjusted signal-space-to-physical-space mapping database.
