ABSTRACT:
To communicate in a press-to-talk (PTT) session, a message for requesting a right to talk in the PTT session is sent over a wireless link between a mobile station and a base station system. The message for requesting the right to talk in the PTT session is sent in wireless signaling over the wireless link. An acknowledgment of the wireless signaling carrying the message is received, with the acknowledgment sent by the base station system in response to the control signaling. An indication is provided at the mobile station of the right to talk in response to the acknowledgment.
