Claims
- 1. A method of estimating uplink and downlink bit error rates (BER) in a radio telecommunications network, said method comprising the steps of:
- monitoring the uplink and downlink BER on a voice channel;
- determining that said uplink and downlink BER are lower than a first set of predetermined thresholds for a specified period of time;
- measuring residual BER on the voice channel uplink;
- measuring the frame erasure rate (FER) on the voice channel uplink;
- determining that the downlink BER, the uplink residual BER, and the uplink FER are lower than a second set of predetermined thresholds for a specified period of time;
- sending a Fast Associated Control Channel (FACCH) message on the FACCH channel downlink;
- estimating the number of bit errors on the FACCH channel downlink;
- converting the number of bit errors to a downlink BER;
- reporting the downlink BER in a message on the FACCH channel uplink; and
- estimating the uplink BER from the message received on the FACCH channel uplink.
