Modelling of the access part of a multi-service mobile network with service priorities

Abstract: This paper presents a methodology for the modelling and optimization of multi-service radio access for universal mobile telecommunications system (UMTS) networks. The paper provides a description of the basis for modelling of a tandem pair: a wideband code division multiple access (WCDMA) interface and a Iub interface. The models involved in the study take into consideration a possibility of setting priorities to a number of selected traffic classes. Particular attention is given to the development of simple c… Show more

“…Just as in the case of the limited-availability group with reservation, Formulas (15), (21), (22) and (23) form a system of confounded equations. To solve them, the iterative process proposed in [57] has to be applied.…”

“…These mechanisms are executed by reservation algorithms and threshold algorithms and make it possible to shape the quality policy (e.g., differentiation of access to limited resources [22]), improve the effectiveness of resource usage (e.g., spectrum efficiency and energy efficiency [23]) and increase the stability of operation of network devices (e.g., load balancing [24]). At the same time, the mechanisms allow streaming, elastic and adaptive services to be performed [1].…”
