    Abstract: A trunked base station (BS) in a trunked radio system tunes its receiver to the hailing channel and monitors for a hailing signal. A subscriber unit (SU) scans a first set of control channels for a control signal transmitted by the trunked BS. In response to failing to locate a control signal on any one of the first set of control channels, the SU tunes its transmitter to a hailing channel and transmits a hailing signal. In response to receiving a hailing signal from a SU, the BS tunes to a transmit portion of a trunked control channel and transmits a control signal. And the BS subsequently tunes to a receive portion of the trunked control channel and monitors for a registration response. Subsequently, the SU scans a second set of control channels for a control signal transmitted by a BS in the system.

    Abstract: Geo-fence based alerts are provided in a wireless communications network. A first subscriber device (SD) in the wireless communications network determines its current location. The first SD detects a geo-fence trigger by determining, as a function of the determined current location and a stored geo-fence database, that it has either (i) crossed a geo-fence boundary into a first active geo-fence in the stored geo-fence database or (ii) is within the first active geo-fence and has not yet begun playing back an alert associated with the first active geo-fence. Responsively, the first SD identifies an alert associated with the first active geo-fence and begins playback of the alert associated with the first active geo-fence.

    Abstract: A radio site controller is configured to dynamically activate adjacent radio sites by first identifying, based at least on a current location of a subscriber unit in a currently activated first radio site, a currently de-activated second radio site located adjacent to the first radio site, and subsequent activating the identified second radio site. The identified second radio site may be a single de-activated adjacent second radio site, all de-activated adjacent second radio sites, or a subset of de-activated adjacent second radio sites based on a subscriber unit travel direction determination.
