A method, apparatus, and computer instructions for managing push-to-talk
communications. Different types of PTT calls with a variety of protocol
configurations are supported with the use of PTT Type and Protocol Type
fields in a call set up control message. When a push-to-media indicator
in a call set up request message is detected in a radio access network in
a communications system, the packet is directed to a push-to-media
gateway in a packet data network in the communications system. The
push-to-media packet is processed using the push-to-media gateway to
manage the push-to-media call. This directing of the packet reduces the
latency in managing a push-to-media call.
