ABSTRACT:
Apparatus and method for reducing latency in push-to-talk communications in a wireless communication network. Time sensitive push-to-talk (PTT) related messages are identified in a specially designated header, so they can be handled differently by radio mobile devices. These messages with the special designated header are transmitted through signaling channels from a radio transmission unit to a mobile device, as opposed to being transmitted as dedicated channel traffic.
