A mobile station ( ) contains a local personality database ( ) in a memory ( ) of the mobile station. The local personality database contains information records ( ), at least one of which has a variable personality parameter, such as a directory number ( ). The directory number may change with either the time of day, geographic location, or both. At the appropriate time, the mobile station transmits a request to a central office ( ) to receive an update of the directory number. The central office searches a parameter database ( ) to find the most recent directory number, and returns it to the mobile station, which stores it for use at a later time. The system can also update scan and channel lists in the same manner.

Method and apparatus for updating a mobile station parameter set

Communication resources are allocated within a radio communication system in anticipation of expected resource requirements using predictions based on information supplied by a subscriber unit. In one embodiment, the system uses the subscriber unit's location history to predict a future location (510, 520, 530). In another embodiment, the system uses radio capability information, along with environment information for the subscriber unit, to predict loading conditions for potential hand-over sites (610, 620, 630), and assigns the subscriber unit to one of the potential hand-over sites based on the predicted loading conditions (640).

Method for optimizing resource allocation based on subscriber

A method of remotely changing an original voice encryption key in a secure radio (10) is provided which includes a central controller (20) transmitting to the secure radio a digital word (42) representing a selective operation to be performed on the original voice encryption key stored in the radio (10). In response to the digital word (42), the radio (10) performs the operation on the original voice encryption key to generate a current voice encryption key.
