Abstract:
A method of estimating available call capacity at a Code Division Multiple Access (CDMA) base station transceiver subsystem, the method comprising the steps of:a) determining available power to support additional calls by said base station transceiver subsystem;b) determining the average power used per channel;c) dividing a value representing the available power to support additional calls by a value representing the average power used per channel to determine the call capacity available;d) measuring the power consumed by each channel in use;e) cumulatively adding values representing the power consumed by each channel in use to obtain a total forward transmit power usage value;f) determining the number of channels in use;g) dividing a value representing the total power usage by the number of channels in use to obtain the average power used per channel; andh) subtracting a value representing the total forward transmit power usage, a value representing a LoCall Blocking Threshold power and a value representing a pilot power of said base station transceiver subsystem from a value representing a maximum allowable total transmit power, to obtain a value representing the available power to support additional calls.
