Abstract
A packet data communication system ( ) that includes a plurality of communication units and a fixed infrastructure comprising a packet data routing system ( ) and a plurality of base sites ( ), emloys a method and apparatus for paging a communication unit ( ). The fixed infrastructure ( ) transmits a paging message to a communication unit ( ) of the plurality of communication units. In response to receiving the paging message, the communication unit ( ) transmits an acknowledgment. If the fixed infrastructure ( ) fails to receive the acknowledgment within a certain waiting period, the fixed infrastructure ( ) waits at least until the expiration of a backoff period before again transmitting a paging message, wherein the length of time of the backoff period is based on a metric of known system behavioral patterns.
