Abstract

The present invention provides a method and an apparatus for controlling mobile access to a wireless communication system. A base station (145) in a communication cell (165) monitors a plurality of mobile access parameters. The base station (145) generates control information based on the plurality of mobile access parameters. The base station (145) provides mobile stations (185, 190) within the communication cell (165) with the control information to control access to the communication system by mobile stations (185, 190) based on the mobile access overload class of the mobile stations (185, 190) and the type of mobile access attempted by the mobile stations (185, 190).
