Abstract
To address the need for a communication unit, a communication infrastructure, and method that shorten call-setup time while still providing the benefit of the QPCH, the present invention provides a communication unit (e.g., 103) that sends a page response before receiving a page message from the communication infrastructure, based on the values of the QPCH indicators. This 'preemptive' page response shortens call-setup time. Because several communication units may send page responses before verifying whether they specifically are being paged, the infrastructure (e.g., 108-110) determines which page responses are valid (and processes them further) and which are false (and discards them).
