GSM channel management using cell load dependent algorithm on air-interface

Abstract

In a congestion situation, some mobile subscribers are disconnected from the network due to network handling capability being limited from the cellular networks. This is despite resource expansion to satisfy the demand for supply for more mobile subscribers. Cell load dependent algorithm is a channel efficient method to increase network handling capability for the cell site having high traffic peaks. By this feature, half rate channels are only assigned during traffic peak hours automatically, and a flexible assignment is provided. Before assigning a channel, the BSC checks the percentage of busy channels and then BSC handles the threshold comparison, evaluation and assignment of the half and full channels to their networks. During off peak time, we can offer higher speech quality via only full rate channels. When cell load dependent mechanism is activated, adaptive multirate for half rate channels will be activated automatically.
