Abstract
A communication system base site (300) receives a signal (400) representing a request from a communication unit (200) to access the communication system (100). The signal includes an identification code (402) and another code which represents when the communication unit was authorized to access the communication system (410). The base site (300) operates to process the identification code (402) to initially determine that the communication unit (200) should not be permitted access to the communication system (100). Additionally, the other code (410) is processed to determine whether the communication unit (200) was authorized to access the communication system (100) within a time interval. If so, the communication unit (200) is permitted to access the communication system.
