1. A location method for a mobile station, the method comprising: identifying a current probable location of the mobile station responsive to a communication of the mobile station through a mobile communication network, the current probable location defined by a position of the mobile station and an uncertainty of the position; identifying, by a processor, a predetermined area which at least partially overlaps the identified current probable location of the mobile station; determining a probability distribution of the mobile station proximate to the predetermined area from the position of the mobile station and the uncertainty of the position, wherein the probability distribution includes: a first probability distribution associated with a radius of the predetermined area, and a second probability distribution associated with the radius of the predetermined area and a distance between the mobile station and a position of the predetermined area; estimating, by the processor, a probability that the mobile station is proximate to the predetermined area from the determined probability distribution, wherein the estimating includes: determining a first plurality of values for the first probability distribution over a range of radius values associated with the predetermined area, determining a second plurality of values for the second probability distribution over the predetermined range of radius values, combining the first plurality of values and the second plurality of values to form a combined plurality of values, determining a mean value of the combined plurality of values, and determining the estimated probability from the mean value; and associating an event for the mobile station based on the estimated probability.
