Performance of queuing priority schemes based on push-out mechanism in mobile cellular systems
Roberto Beraldi, S. Marano, N. Ungaro · 2002
This paper presents three new push-out based queueing priority schemes, suitable for mobile cellular networks. In such schemes, named originating calls (OC) push out (POC), OC threshold push out (T-POC) and partitioned OC push out (P-POC), handoff calls (HC) and originating calls are both queued and a service selection policy based on the measurement of the received signal measurement based prioritization scheme, in addition to the simpler FIFO policy has been used. The proposed strategies are studied by means of simulations for different percentages of HC, selected according to the radius of the cells. The performance achieved is superior with respect to classic schemes based on only HC queueing and to the nonprioritized scheme.
