Radio telephone system supporting automatic busy and out-of-range indications
First Claim
1. In a radio telephone communication system having:
- a base station with at least one frequency agile transceiver capable of time division duplex operation on at least one radio frequency channel for facilitating communication with at least one radio telephone on the at least one radio frequency channel, a method of determining acquisition status of the at least one frequency agile transceiver in the base station comprising the steps of;
at a radio telephone;
scanning a plurality of channels capable of being generated by the at least one frequency agile transceiver to find an available channel, the plurality of channels including the at least one radio frequency channel; and
providing an indication representing a base station busy status when all of the at least one frequency agile transceivers are in use indicating no available channels as determined when one of;
bidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver on the at least one radio frequency channel; and
unidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver on the at least one radio frequency channel.

Abstract
A radio telephone communication system (200) having a base station (203) including at least one frequency agile time division duplex transceiver (207) for facilitating communication with at lest one radio telephone (100) on the at least one radio frequency channel. The radio telephone (100) scans a plurality of channels capable of being generated by the at least one frequency agile transceiver (207) to find an available channel and provide an indication representing a base station busy status when all the at least one frequency agile transceivers are in use. A base station busy status is indicated when one of a bidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver or a unidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver (207).
