Abstract: A first Mobile Repeater System (MRS), configured to serve as an access point associated with a Basic Service Set (BSS), broadcasts a Basic Service Set Identifier (BSSID). Other Mobile Repeater Systems (MRSs) join the BSS to create a local ad hoc trunked site in which each of the MRSs are communicatively coupled via at least one WLAN communication link. These MRSs include the first MRS and a second MRS. The first MRS can be configured to provide a control channel for communication with a first subscriber unit, and the second MRSs can be configured to provide a first trunked traffic channel for communication with the first subscriber unit.

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.
