REPEATER FOR A TRUNKED RADIO NETWORK
First Claim
1. A repeater for a trunked radio network, including:
- a first transceiver for wireless communication with the trunked network, and a second transceiver coupled to the first transceiver for wireless communication with a radio terminal,wherein the first transceiver transmits and receives control signals on a full duplex or half duplex link with the trunked network, and the second transceiver transmits and receives corresponding control signals on a half duplex or simplex link with the radio terminal.

Abstract
A repeater which enables portable radio terminals to operate outside the normal coverage area of a trunked radio network. The repeater combines two wireless transceivers which may simply be radio terminals coupled together in a vehicle, for example. One transceiver communicates control messages to and from the trunked network using a full or half duplex channel. The other transceiver communicates with the portable terminals using a half duplex or simplex channel. The link from the repeater to the network includes a generally continuous control channel while the link to the portable terminals is generally non continuous with intervals for messages from the terminals back to the repeater.

9. A method of operating a repeater to provide a composite control channel on a half duplex or simplex link, including:
-
receiving control messages broadcast as a generally continuous signal by a trunked radio network, broadcasting corresponding control messages over the link to a radio terminal as a generally non continuous signal, and receiving control messages from the radio terminal over the link as a generally non continuous signal. - View Dependent Claims (10, 11, 12, 13)

14. A method of operating a radio terminal on a simplex or half duplex link with a repeater in a trunked radio network, including:
-
receiving one or more repeater radio bursts on the link, containing control messages broadcast by the repeater, waiting for an interval between the repeater radio bursts, and transmitting a radio terminal burst on the link during the interval, containing control messages for the repeater. - View Dependent Claims (15, 16)

17. A radio terminal for a trunked radio network, including a transceiver which is programmed to carry out the following steps:
-
hunt for messages on a generally continuous control channel provided by the network, and in the absence of a continuous control channel, hunt for messages on a generally non continuous control channel provided by a repeater. - View Dependent Claims (18, 19, 20)
