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).
