Förfarande, nät, nätelement och mobiltelefon för att slå läger inom en cell i ett mobilkommunikationsystem

摘要

In a mobile communications system exclusive location areas comprising exclusive cells are defined in order to separate cells from the mobile stations not belonging to the user group allowed to camp in the cell and still to allow emergency calls for all mobile stations in these cells. During location update it is checked whether the cell belongs to an exclusive location area (202) and if it does, it is determined whether or not the subscriber is allowed to camp in the cell.
