Abstract
Timers in push-to-talk (PTT) enabled client devices are used to regulate packet traffic to and from the client device. In one embodiment, timers are used to maximize the user experience that occurs when the presence service is enabled in the PoC System. A first timer controls the flow of presence requests coming uplink from the UE to the presence server, and a second timer controls the flow of presence messages coming downlink from the presence server to the UE and associated presentation on the Man-Machine-Interface (MMI).
