Abstract
The present invention allows for communication devices (106 and 108) operating in a communication system (100) to be guaranteed of not missing any important system message sent by the communication system controller (104). By transmitting a system time code to the communication devices (106 and 108) the system controller (104) can inform the communication devices when they need to be ready to receive information from the system controller (104). Once the time to receive a message is determined, the communication devices (106 and 108) turn on even if they were presently turned off or in a battery saving (low power) condition.
