<p>This coordinated floor and packet scheduling for Push-to-X over Cellular (PoC) services delays a packet data slot assignment until after a PoC floor has been granted (272) by a PoC server (251). By reducing the time period between slot assignment and floor grant, this method reduces the wasting of packet data network resources while the communication device (211) is waiting for a PoC floor grant. Setting up a Push-to-X over Cellular (PoC) call session includes an originating communication device (211) transmitting a PoC floor request message (270) to a PoC server (251), the PoC server (251) sending a PoC floor grant message (272) with treatment type "floor grant" to a packet control function, (232), the packet control function (232) assigning packet data slots to the originating communication device and setting up an active packet data session (280), and communicating a PoC floor grant and packet data slot assignment message (285) to the originating communication device (211).</p> |
