Congestion is a disturbing phenomenon in Global System for Mobile Communication (GSM) Network as it leads to loss of call and/or degradation in quality of service. Several measures for controlling this such as discarding policy, acknowledgement, etc. have not been able to handle congestion based on resource allocation. In this book, a scheme that adapts user"s traffic to network prevailing conditions by dynamically allocating channels using one-level buffering technique with ticket scheduling algorithm was developed. The new scheme improves the network performance and increase resource utilization.
