METHOD AND APPARATUS FOR PROVIDING A LOW-LATENCY, HIGH-ACCURACY INDICATION-TO-SPEAK

The method described herein is useful in a push-to-talk over cellular (PoC) system to provide an accurate but low-latency indication-to-speak. Generally, the method may be referred to as a page-event confirmed indication-to-speak. The page-event confirmed indication-to-speak accurately confirms a targeted but dormant mobile station is within radio reach by first sending a paging message to the dormant mobile station. When the dormant mobile station responds to the page message, an indication-to-speak is delivered to an initiating mobile station to indicate to the user that he/she may now speak.
