Effect of number of channels on service parameters for third generation mobile communication systems
N. Padovan, L.C. Godara, Michael J. Ryan · 2002
Satellite and terrestrial cellular communication systems currently exist as two independent environments. In third generation systems these will complement each other and cooperation between the two will allow for flexible and optimal radio resource allocation resulting in reduced cost. However, the success of third generation systems over existing first and second generation systems will largely depend on their ability to provide improved quality of service, global coverage and an increased subscriber population. This paper describes a teletraffic model suitable for such a multilayer system. It determines the benefits associated with a multi-layer topology by changing the number of layers and the number of channels that can be supported by each layer to determine their effects on the performance parameters (probability of blocking, probability of handoff and probability of forced termination) and quality of service.
