摘要：

We will present an algorithm for enhanced AMR mode switching for VoIP over GERAN that takes into account abstract criteria like frame delay and packet loss rate at the application layer, as well as segmentation overhead at the data link layer. With the proposed algorithm in a wireless terminal, dynamic cross-layer optimization between the VoIP application and the radio network control can be achieved even if the peer codec is situated far away from the air interface. The performance improvements of the algorithm will be demonstrated for a typical GERAN scenario in terms of achieved speech quality, as well as resource consumption and utilization efficiency at the air interface.
