Base station feedback reporting system
First Claim
1. In a mobile telephone system, a system for reporting to a control terminal the operational status of a base station equipment being responsive to a control signal sent from the control terminal on an audio channel, the system comprising:
- means at the control terminal for sending on the audio channel an encoded control signal of uniform time interval from the control terminal to the base station;
means at the base station for receiving and decoding the encoded control signal to initiate a predetermined base station function;
means for sending to the control terminal from the base station on the audio channel an encoded report signal of uniform time interval indicative of a predetermined operational status of the equipment at the base station; and
means for receiving the encoded report signal at the control terminal.

Abstract
The operational status of equipment located at a base station is reported to a remote control terminal. The same audio channel that is used for sending audio signals and control signals to the base station is also used to carry the report signal. The control signals to the base station and the report signals from the base station are encoded tone burst signals. The report signal provides an indication of the proper receipt and execution of a control signal by the base station equipment. Equipment diagnostic signal and periodic checks of equipment performance are also reported by this system.

7. In a mobile telephone system, a system for reporting to a control terminal the operational status of a base station equipment, said base station equipment being responsive to a control signal sent from the control terminal on an audio channel, the system comprising:
-
means at the control terminal for sending on the audio channel an encoded control signal of uniform time interval from the control terminal to the base station; means at the base station for receiving and decoding the encoded control signal to initiate a predetermined base station function; means for sending to the control terminal from the base station on the audio channel an encoded report signal of uniform time interval indicative of a predetermined operational status of the equipment at the base station; means for receiving the encoded report signal at the control terminal; means for including in said encoded report signal, in sequence, a high level guard tone burst, a low level function tone burst, a no-signal time period, and a low level guard tone;
means for including in said encoded report signal a tone burst present during the no-signal time period;means for adding an idle-channel tone signal to the low-level guard tone, said idle-channel tone indicative of an available mobile telephone channel, signal sending means for sending a tone burst at predetermined intervals, said tone burst indicative of proper system operation; and means at the control terminal for detecting the tone bursts at predetermined intervals.
