Network Slicing – the concept

Smartphone Slice 1 (e.g. for the network operator’s subscribers)

Smartphone Slice 2 (e.g. for a virtual operator’s subscribers)

Vehicle Services Slice 1 (e.g. for a truck manufacturer’s fleet assistance)

M2M Service Slice 1 (e.g. for a goods or container tracking system)

Overall Operator Network (PLMN)

UE (Radio) Access Network Core Network applications

Network Slicing enables the network operator to deploy multiple separate end-to-end logical networks sharing the same or using separate infrastructure.Each network slice can be customized independently for different application and/or business scenarios/usages (SLAs).

Features are not always independent from each other. E.g. (very) UE low battery power consumption competes with obtaining

services via multiple network slices. As an example, network slices #1 and #2 are for different IoT usages with on the same UEs

sharing common NFs. While network slice #3 could be for smartphones.
