Method and system to calculate an approximate location of a mobile station in a recurrent route
First Claim
1. A method of training a mobile station location identification system for a recurrent route, the method comprising:
- decoding a first unique identifier that uniquely identifies a first cell of a cellular system that is in communication with a mobile station when the mobile station is located at a first location with respect to the first cell at a first time; and
decoding a second unique identifier that uniquely identifies a second cell of the cellular system that is in communication with the mobile station when the mobile station is located at a second location with respect to the second cell at a second time;
wherein the first and second unique identifiers and the first and second times are configured to be used by the mobile station location identification system to automatically identify the location of the mobile station at a particular time along said recurrent route.

Abstract
A method and system for calculating the approximate location of a mobile station along a recurrent route is disclosed. In an embodiment for the method in accordance with the principles of the present invention, the method for storing reference data includes decoding a first unique identifier for a cell in communication with the mobile station at a first location and a first time, storing the first unique identifier and the first time, decoding, upon handoff to a next cell, at a second location and at a second time, a second unique identifier for the next cell, and storing the second cell identifier and the second time. In a method for calculating an estimated time of arrival at the endpoint of a segment for a mobile station traveling along a recurrent route of travel, the method includes detecting the startpoint of one of the plurality of segments at a first time, and calculating an estimated time of arrival at the endpoint of the segment. In an embodiment of a system in accordance with an embodiment of the invention, the system includes a mobile station, a first cellular base station, a second cellular base station, a database, and a processor.

15. A system for calculating an approximate location of a mobile station along a recurrent route of travel between a first location and a second location, the system comprising:
-
a first cellular base station configured to provide cellular coverage to the mobile station in a first cell including the first location; a second cellular base station configured to provide cellular coverage to the mobile station in a second cell including the second location; a database configured to store a previously measured time of travel of the mobile station from the first location to the second location, the previously measured time of travel having been calculated by a method including subtracting (1) a first time at which the mobile station was at the first location as determined by the mobile station receiving the first cellular base station identifier, from (2) a second time at which the mobile station was at the second location as determined by the mobile station receiving the second cellular base station identifier; and a processor configured to automatically calculate the approximate location of the mobile station at a particular time along the recurrent route of travel between the first location and the second location using the previously measured time of travel stored in the database. - View Dependent Claims (16)

17. A method of training a mobile station location identification system along a recurrent route, the method comprising:
-
decoding a first unique identifier that uniquely identifies a first cell of a cellular system that is in communication with a mobile station when the mobile station is located at a first location with respect to the first cell at a first time; decoding a second unique identifier that uniquely identifies a second cell of the cellular system that is in communication with the mobile station when the mobile station is located at a second location with respect to the second cell at a second time; calculating a travel time for travel between the first location and the second location by subtracting the second time and the first time; and storing the travel time in the mobile station, wherein the first and second unique identifiers and the travel time are configured to be used by the mobile station location identification system to automatically identify the location of the mobile station at a particular time along the recurrent route, and wherein at least one of the first unique identifier and the second unique identifier is one from a group including a Cell Tower Identification Number and a Base Station Identifier. - View Dependent Claims (18, 19, 20)
