Abstract

An apparatus and method of messaging service message control on a wireless communication device. The push-to-talk usage of a device is monitored. A push-to-talk metric is determined based on the push to talk usage of the device. A push-to-talk session unavailability mitigation is selected based on the push-to-talk metric. The session unavailability can be a delay of an activation of a push-to-talk session, an interruption of a push-to-talk session, or any other event that can adversely affect a push-to-talk session.
