“…The connection is characterized by a transmission rate, hereafter denoted by R bh b , a transmission delay T bh b and a scheduling policy. Since the BH can be implemented with a wide range of technologies, such as wireless or x Digital Subscriber Line (xDSL) [29], [30], none of the technologies is precluded. However, BH capacity is assumed to be constrained.…”

In this paper, we propose the Base Station (BS) Agnostic Framework for Network SliCing, NetSliC, that creates network slices for the Radio Access Network (RAN) based on the service requirements. Current cellular RAN is a heterogeneous complex architecture, comprising legacy distributed Small Cells (SCs), Radio Remote Radio Heads (RRHs) connected to a centralized Base Band Unit (BBU), and future 5G NodeBs (gNBs) leveraging virtualization with different functional splits, serving distinct traffic profiles. Thus, NetSliC is a common language that manages and controls this heterogeneous infrastructure. We consider several criteria for creating network slices in this particularly interesting future scenario, which are applicable to all different types of access and transport interfaces of the distinct BSs. The goal of our work is to propose NetSliC, a framework that creates wireless slices in a cellular RAN independently of the type of BS (i.e., BS agnostic) and on the same time achieves desirable service capability across the various traffic profiles.

“…Such approach is not entirely correct, since in modern cellular networks a User Equipment (UE) can operate with only one Base Station (BS) at a time, and not with all network at once: a UE will transmit the data with the delays of a particular cell, and not with the average delays of the entire cellular mobile network (see Figure 1 for more details). At the same time, the cell performance largely depends on the implementation of the terrestrial backhaul link (which also is called a "first mile link") connecting BS with the core network, and the implementations of the terrestrial backhaul interface can be various: from fibre optic cables (usually used in densely populated areas) to multi-hop radio links (usually used in rural areas) [16]. Further, the modulation and coding scheme of a UE is dynamically selected according to the quality of a radio signal.…”

The ability to describe experimentally obtained delay values in a cell of a mobile cellular network allows not only describing the properties of cell delays using only a few parameters, but also to simulate delay values. Unfortunately, occasionally occurring temporary unstable operation of a cellular network, caused by various negative factors, leads to a noticeable increase in delays and, as a result, to a significant distortion of the obtained delay parameters estimates. For this reason, estimates of the delay parameters in a cell should be obtained from experimental data obtained at the time of stable operation of the network. Due to the large amount of experimentally obtained data, the process of checking experimentally obtained delay values for the presence of anomalies should be performed on the application of simple criteria. The aim of this paper is to show an approach to obtaining stable parameter estimates of delay in a cell of a mobile cellular network. The article describes the factors that affect delays stability, assesses the degree of their influence, and also highlights properties that can be used to recognize phenomena that adversely affect the value and stability of delays in order to exclude such experimentally obtained data from the evaluation.
