Description

ABSTRACT:
A telecommunications system and method is disclosed for analyzing the speech quality, e.g., the Bit Error Rate (BER), on the forward and reverse links to determine whether the links are balanced. For a target cell, the BER on the forward and reverse links can first be measured. The determination of whether the links in the target cell are balanced depends upon whether the BER percentage is known or only the BER class information is available. If the BER percentage is known, the relative difference of the mean BER on the reverse and forward links can be compared to determine the degree of the balance. However, if only the BER class is available, the relative distribution of occurrences of the BER classes on the reverse and forward links can be analyzed to determine whether the links are balanced. The analysis of the path balance can also be used to benchmark speech quality balance in cellular systems.
