Abstract

A new dynamic channel assignment (DCA) scheme specifically adapted for the GSM system is introduced and evaluated. This functionality is fully compatible with the existing GSM standards and therefore it can be implemented in existing GSM networks with legacy handsets. The channel assignment decisions are based on the downlink measurement and radio resource usage data that are already available in the base station controller. The performance is evaluated by simulations benchmarking the performance against a state of the art fractionally loaded synthesised hopping network. The simulations are made in a dynamic network level simulation tool considering all the normal system limitations and radio channel impairments. The results show a significant increase in obtainable network capacity
