Blocking probaffity analysis of new and handover calls in cellular mobile networks with repeated attempts
Г. П. Башарин, V.E. Merkulov · 2003
It is known that ellieient call handling mechanisms can greatly improve cellular network performance. Bowerer, nuidern cellular mobile network dimensioning is often based an rough estimates than on realistic analytical models for the applied protocols and expected traffic behavior. The application of more detailed traffic models shows, that actual load and probabilktic traftic properties considerably differ from those used for ertima- tion. This can lead to inaccurate calculation of QaS pnrameters and network operator costs. In this paper we consider call han- dling schemes in cellular mobile networks based nn complete shar- ing and guard channels for lhe case of blocked call retries. We present a simple analytical method for approximate calculation of blocking probabilities for this case. As a part of the method we derive the average number of failed repeated attempts per one blocked call which we consider to he an important parameter in cost calculation.
