Method and device to support site activation using a hailing channel
First Claim
1. A subscriber unit configured to communicate via a trunked radio system, the subscriber unit comprising:
- a memory;
a transceiver comprising a transmitter and a receiver; and
a processor configured to;
scan, via the receiver, a first set of one or more preconfigured control channels for a control signal transmitted by a trunked base station in the trunked radio system;
responsive to failing to locate a control signal on any one of the first set of one or more preconfigured control channels;
tune the transmitter to a preconfigured hailing channel and transmit, via the transmitter, a hailing signal on the hailing channel; and
subsequently scan, via the receiver, a second set of one or more preconfigured control channels for a control signal transmitted by a trunked base station in the trunked radio system.

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.

12. A trunked base station comprising:
-
a memory; a transceiver comprising a transmitter and a receiver; and a processor configured to; tune the receiver to a pre-configured hailing channel and monitor the hailing channel for a hailing signal indicating a presence of a subscriber unit within the base station'"'"'s coverage area; and responsive to receiving a particular hailing signal from a particular subscriber unit, tune the transmitter to a transmit portion of a pre-configured trunked control channel and transmit, via the transmitter, a control signal, and tune the receiver to a receive portion of the pre-configured trunked control channel and monitor, via the receiver, for a registration response to the control signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
