Abstract:
|
Network slicing is a fundamental feature of 5G
systems that facilitates the provision of particular system
behaviours adapted to specific service/application domains on top
of a common network infrastructure. A network slice is in general
composed by a core network slice and a Radio Access Network
(RAN) slice. The realization of RAN slices is particularly
challenging because it requires configuring and operating traffic
differentiation and protection mechanisms to simultaneously
deliver multiple and diverse RAN behaviors over a given pool of
radio resources. In this context, this paper proposes to
characterize the behavior of a RAN slice through the specification
of a set of control parameters that are used to dictate the operation
of the packet scheduling function at Layer 2 and the radio
admission control function at Layer 3. An evaluation of the
suitability of these parameters for achieving efficient radio
resource sharing and isolation between RAN slices is presented
when configuring a network for supporting a slice with multiple
enhanced Mobile BroadBand services and another slice for
providing Mission Critical services. The analysis reveals the
different impact of the Layer 3 and Layer 2 parameters for
isolating services of different slices depending on whether they
require guaranteed or non-guaranteed bit rates. |
