A method and apparatus for tracking a position of a mobile radio unit within a communication system. The mobile unit uses information from earth orbiting satellites and/or information received from infrastructure of the system to dynamically select alternative operating parameters. The method includes providing a controller and storing a look-up table in memory coupled to the controller. The method further includes a calculating a position of the mobile unit using measurements from the earth orbiting satellite system and/or the system infrastructure. Position values from the look-up table are compared with that of the position of the mobile radio unit in order to determine the geographical location of the mobile unit from the look-up table. At least one operating parameter is then dynamically selected based upon the determined geographical loacation. In preferred embodiments, the mobile radio unit dynamically selects either a specific language in which to display menu options or an encryption scheme based on the determined geographical location. |
