Abstract
In a wireless communication system, unauthorized access may be prevented upon detecting the particular type of identification code. When the identification code is of a default enabled type, the central controller (101) transmits a default enabled message to the system manager (110). The system manager interprets this message and provides a response to the central controller (101). The response may indicate that this particular identification code should be activated or deactivated.
