METHOD AND DEVICE TO SUPPORT SITE ACTIVATION USING A HAILING CHANNEL

摘要

A BS 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 a trunked base station (BS) in a trunked radio system. 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.

主权项

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; andsubsequently 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.
