Abstract: A method for enhanced data throughput on a windowed revert repeater channel in a radio communication system includes requesting, by a subscriber unit and via a control channel of the radio communication system, a window in which to transmit data updates on the windowed revert repeater channel of the radio communication system; receiving, by the subscriber unit and via the control channel, an assigned window on the windowed revert repeater channel for the data updates; monitoring, by the subscriber unit, the control channel repeater and determining a timing of the windowed revert repeater channel based on the monitoring; and reverting to the windowed revert repeater channel based on the timing and the assigned window, and transmitting the data updates during the assigned window. A subscriber unit and radio communication system are also disclosed.

Abstract: A communication system is provided that alerts a public safety officer to missed Push-to-Talk (PTT) group calls. The communication system allows a public safety officer's radio to record a last stop working time. A public safety network then can search a missed call list associated with the public safety officer and automatically push a notification of missed PTT group calls to the public safety officer's radio when the radio re-joins the public safety network. Based on the notification, the public safety officer can choose to review or replay any missed calls to avoid missing important information.
