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, during a real-time multimedia session, a suspend timer is activated during data communication channel suspension. The session is held until suspend timer times out. If the data communication channel is restored before the suspend timer times out, the session is not reset, and the user is still able to continue the session with little noticeable loss of service. If the suspend timer times out, and the data communication channel has not been restored, then the session is terminated.
