Radio telephone system supporting busy and out-of-range function
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;
providing an indication representing a base station busy status when one of;
requesting a communication link fails and bidirectional time division duplex communication exists on the at least one radio frequency channel; and
requesting a communication link fails and unidirectional time division duplex communication exists on the radio frequency channel and the unidirectional time division duplex communication originates from the base station.

Abstract
A radio telephone communication system (200) comprising a base station with at least one frequency agile transceiver (207) capable of time division duplex operation on at least one radio frequency channel. The base station operates to facilitate communication with at least one radio telephone (100) on the at least one radio frequency channel. The radio telephone communication system further comprises a radio telephone (100) capable of determining an acquisition status of the at least one frequency agile transceiver in the base station, the radio telephone (100) generating an indication representing a base station busy status (402) when one of: requesting a time division duplex communication link fails and bidirectional time division duplex communication is exists on the radio frequency channel; and requesting a time division duplex communication link fails and unidirectional time division duplex communication exists on the radio frequency channel and the unidirectional time division duplex communication originates from the base station.
