1. A method for generating a profile representing a geographic region in a radio communications network comprising the steps of:
- obtaining a probability for each of a plurality of cells that the cell will be selected as a serving cell by a mobile radio terminal in the geographic region; and
processing at least one probability to generate a profile representing the geographic region.

Abstract
A method and system for determining whether a mobile radio terminal is in or out of a zone in a radio communications network by relying at least partially on a serving cell identity. The method provides for generating a profile representative of the zone using measurements taken by the mobile radio terminal, the network, and/or using predicted values. A comparison is then made to determine whether the mobile radio terminal is in or out of the zone.

10. A method for determining whether a mobile radio terminal is within a predefined geographic region comprising the steps of:
-
receiving a serving cell identity; comparing a profile representing the predefined geographic region with the serving cell identity; determining whether the mobile radio terminal is within the predefined geographic region based on the comparison; calculating a cost associated with the received serving cell identity; and comparing the cost with a zone detection probability threshold. - View Dependent Claims (11, 12, 13, 15, 16, 18)

19. A method of adjusting a profile representing a geographic region in a radio communications network, the method comprising the steps of:
-
obtaining a profile having a probability for each of a plurality of cells that the cell is selected as a serving cell by a mobile radio terminal in the geographic region; adjusting a parameter of the profile; and re-calculating a probability for each of the plurality of cells that each cell will be selected as a serving cell by a mobile radio terminal in the geographic region based on the adjusted parameter.
