1. A method for training a mobile station location identification system for calculating the approximate location of the mobile station along a recurrent route that crosses a boundary between a first cell coverage area and a second cell coverage area located between a startpoint of the recurrent route and an endpoint of the recurrent route, the method comprising:

  • detecting a start of a trip at the startpoint of the recurrent route at a first time;

    storing in the mobile station the first time and a value representing the startpoint;

    detecting the mobile station crossing the boundary between the first cell coverage area and the second cell coverage area at a second time;

    storing in the mobile station the second time and a value associated with the location along the recurrent route of the mobile station crossing the boundary;

    detecting an end of the trip at the endpoint of the recurrent route at a third time; and

    storing in the mobile station the third time and a value representing the endpoint.
