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; estimating, by the processor, a probability that the mobile station is proximate to the predetermined area from the determined probability distribution; and associating an event for the mobile station based on the estimated probability.
