Abstract
A method and apparatus used by a communication system (100) to optimize the re-registration of communication system users that use a variable speed multiple-user communication unit (VSMCU) (110). VSMCUs (110) can be located on mobile vehicles, these mobile vehicles can move at different speeds at different times. VSMCUs (110) can collect registration information, obtain velocity information, determine re-registration distances, and determine re-registration factors. VSMCUs (110) send re-registration factors to the system. The system uses the re-registration factors to determine a modified ring-alert area for the associated VSMCU.
