One of the main goals of 5G networks is to support the technological and business needs of
various industries (the so-called verticals), which wish to offer to their customers a wide …

Thanks to its computational and forwarding capabilities, the mobile network infrastructure
can support several third-party (“vertical”) services, each composed of a graph of virtual …

To efficiently serve heterogeneous demands in terms of data rate, reliability, latency and
mobility, network operators must optimize the utilization of their infrastructure resources. In …

In this paper we investigate the allocation of resources to slices on the radio interface of one
cell. In particular, we develop a detailed stochastic model of the behaviour of the sliced cell …

Through their computational and forwarding capabilities, 5G networks can support multiple
vertical services. Such services may include several common virtual (network) functions …

In this article, we develop a modeling framework to describe the uplink behavior of radio
access in a sliced cell, including most features of the standard 3GPP multiple access …

The limited capacity of the random access channel (RACH) represents a challenge for
adequate resource allocation in 5G radio access networks with network slicing. Furthermore …

Network function virtualization is one of the most relevant enabling technologies for 5G:
conceiving a vertical service as a set of virtual network functions (VNFs) makes it possible to …
