PURPOSE: A present invention relates to wireless communication systems, and more particularly, to a method and apparatus for the management of authentication keys (A-keys) which are used to authenticate mobile stations in a cellular radio system. CONSTITUTION: A present invention allows a mobile station to receive a command entered by a user for selecting among a plurality of possible values for an authentication key (A-key) stored in its memory, including a default value, a random value and a custom (user-defined) value for the A-key. In response to the command, the mobile station can set the A-key in its memory to the default value or to an internally generated or previously stored random value, or to the custom value entered by the user. The command, whether for selecting the default, random or custom A-key value, may be entered during number assignment module (NAM) programming of the mobile station. |
