1. A method of detecting when a mobile communication device exits a defined geographical area wherein said defined geographical area includes one or more cells, said method comprising:
- identifying a cell that said mobile communication device is in communication with;
determining if said identified cell is a boundary cell, wherein a boundary cell is a cell in which a boundary of said defined geographical area is within said cell;
determining a location of said mobile communication device if said identified cell is said boundary cell; and
comparing said location of said mobile communication device with said boundary of said defined geographical area to detect if said mobile communication device has exited said defined geographical area.

Abstract
The present invention relates to methods and apparatus for detecting when a mobile communication device exits a defined geographical area wherein the defined geographical area includes one or more cells. A cell that the mobile communication device is in communication with is identified and it is determined if the identified cell is a boundary cell, wherein a boundary cell is a cell in which a boundary of the defined geographical area is within the cell. The location of the mobile communication device is determined if the identified cell is a boundary cell and the location of the mobile communication device is compared with the boundary of the defined geographical area to detect if the mobile communication device has exited the defined geographical area.

15. A computer program product embodied on a computer-readable medium, for detecting when a mobile communication device exits a defined geographical area wherein said defined geographical area includes one or more cells, said computer program product comprising computer readable executable code which, when run on a processor, controls said processor to perform a method comprising:
-
identifying a cell that said mobile communication device is in communication with; determining if said identified cell is a boundary cell, wherein a boundary cell is a cell in which a boundary of said defined geographical area is within said cell; determining a location of said mobile communication device if said identified cell is said boundary cell; and comparing said location of said mobile communication device with said boundary of said defined geographical area to detect if said mobile communication device has exited said defined geographical area.
