Claim Text:
1. A method comprising: receiving, by a wireless terminal, a command for initiation of a new media transmission via a push-to-talk (PTT) session over a mobile communications network, wherein the PTT session comprises a previously established session; generating, by the wireless terminal, a media access control layer (MAC layer) PTT request message, and transmitting the MAC layer PTT request message, via a wireless channel of the mobile communications network without requesting an uplink resource allocation for the MAC layer PTT request message, to a wireless gateway of the mobile communications network, wherein the MAC layer PTT request message is configured based on a MAC layer control messaging protocol that is applied for reduced resource requirements and reduced latency over the wireless channel; generating, by the wireless gateway, a Talk Burst (TB) request message based on the MAC layer PTT request message and transmitting the TB request message to a remote PTT server; and receiving, in response to the MAC layer PTT request message, a TB grant message from the wireless gateway indicating that floor control for the PTT session has been granted to the wireless terminal, wherein the TB grant message is received via a Talk Burst Control Protocol (TBCP) bearer and is based on a TB grant message from the remote PTT server.
