1. A method for enabling fast and efficient Push-to-Talk (PTT) service in a network comprising:
- selectively identifying a call where a packet discard policy should be applied based upon a received property associated with the call; and
applying the packet discard policy to the selected call in order to selectively discard packets associated with the call when a triggering event occurs.

Abstract
A call where a packet discard policy (132) should be applied is selectively identified based upon a received property associated with the call. The packet discard policy (132) is applied to the selected call in order to selectively discard packets (134) associated with the call when a triggering event (136) occurs.

14. A method for discarding packets comprising:
within a cellular infrastructure;
receiving a plurality of packets associated with an ongoing call;
selectively identifying whether the ongoing call should have a packet discard policy applied based upon a property associated with the ongoing call;
detecting a triggering event; and
applying the packet discard policy to the ongoing call to selectively discard some of the plurality of packets associated with the ongoing call whenever the triggering event occurs. - View Dependent Claims (15, 16, 17)

18. A device for discarding packets within a cellular infrastructure comprising:
-
a receiver having an input;
a memory for storing a predetermined packet discard policy; and
a controller coupled to the receiver and the memory, the controller being programmed to receive a plurality of packets associated with a call at the input of the receiver, to identify whether the call is in need of application of the packet discard policy, to receive a trigger event at the input of the receiver and, responsively, to apply the packet discard policy to the call in order to selectively discard at least some of the plurality of packets associated with the call. - View Dependent Claims (19, 20)
