Abstract: A method for controlling push-to-talk over cellular (PoC) media burst time includes receiving a burst request time from a PoC client, identifying a burst allocation time corresponding to the PoC client in a database, selecting a burst time for the PoC client based on the burst allocation time and the burst request time, and allowing a data burst from the PoC client at the burst time. A system to control PoC media burst time includes an information receiver to receive the burst request time, an information identifier to identify the burst allocation time for a database, a time selector to select the burst time, and a burst allowing unit to allow the data burst from the PoC client at the selected burst time.
