Probabilistic Location Prediction for a Mobile Station
First Claim
1. A server configured to collect data of when, where and at what received signal strength indication mobile stations roam in a wireless local area network, and to dynamically calculate from said data a coverage area of an access point in said wireless local area network.

Abstract
A probabilistic prediction is made of the location of a wireless-enabled mobile station in a wireless local area network. The prediction includes calculating a vector representing movement of the mobile station through a space in which two or more access points of the network are located, and determining a region surrounding the vector in which the mobile station has at least a given probability to be located within a certain period of time.

- 1. A server configured to collect data of when, where and at what received signal strength indication mobile stations roam in a wireless local area network, and to dynamically calculate from said data a coverage area of an access point in said wireless local area network.
- 6. A server configured to calculate a vector representing movement of a wireless-enabled mobile station through a space in which two or more access points of a wireless local area network are location and to determine a region surrounding said vector in which said wireless-enabled mobile station has at least a given probability to be located within a certain period of time, wherein said vector is calculated based, at least in part, on information that is specific to a group or class of users to which the user of said mobile station belongs.

15. A method for probabilistic prediction of a location of a mobile station in a wireless local area network, the method comprising:
-
calculating a vector representing movement of said mobile station through a space in which two or more access points of said wireless local area network are located; and determining a region surrounding said vector in which said mobile station has at least a given probability to be located within a certain period of time, wherein as said mobile station moves from a stationary state, said region is a deformed circle that is deformed in a direction of motion of said mobile station. - View Dependent Claims (16, 17, 18, 19, 20)
