Abstract
In this paper model of integrated voice/data cellular wireless networks (CWN) are investigated. The unified approximate approach to calculate the desired Quality of Service (QoS) metrics in an isolated cell of such networks under two multi-parametric call admission control (CAC) strategies is developed. One of them is based on the guard channels scheme while the second is based on a threshold scheme. Results of the numerical experiments are given and a comparison of QoS metrics under different CAC strategies is carried out.
Highlights
A cellular wireless network (CWN) consists of radio access points, called base stations (BS), each covering a certain geographic area
In this paper we introduce a unified approach to approximate performance analysis of two multi-parametric call admission control (CAC) in a single cell of un-buffered integrated voice/data cellular wireless networks (CWN) which differs from known works in this area
First briefly consider some results for the CAC based on the guard channels strategy in the integrated voice/data model with four classes of calls
Summary
A cellular wireless network (CWN) consists of radio access points, called base stations (BS), each covering a certain geographic area. In the overwhelming majority of available work, one-dimensional queuing models of call handling processes in an isolated cell of mono-service CWN are proposed These models cannot describe the studying processes in multi-service CWN since in such net-works calls of heterogeneous traffic differ significantly with respect to their bandwidth requirement and arrival rate and channel occupancy time. The proposed approach allows overcoming an assumption made in almost all of the known papers about equality of handling intensities of heterogeneous calls Due to this assumption the functioning of the CWN is described with one-dimensional Markov chain (1-D MC) and authors managed simple formulas for calculating the QoS metrics of the system.
