After this function is enabled, the BTS estimates the long-term voice quality (indicated by the long-term FER(frame erase ratio)) and compares the estimated result with the specified target voice quality. If the estimated result does not conform to the target voice quality, it indicates that the current AMR handover threshold may not be the best for the current radio conditions.

Number PredictedBSC6900SET GCELLPWR2(Optional)Number of downlink AMR measurement reports that the BSC predicts. The BSC takes a while to confirm the power control effect of a power control command. Thus, the BSC makes a power control decision based on a measurement report that lags behind the changes in the receive level and quality instead of reflecting the real-time radio environment. As a result, the power control is late.To prevent late power control to a certain degree, the power control algorithm involves a measurement report prediction filter.
