As per GSMA report, 5G networks in combination with network slicing help business customers to enjoy connectivity to the specific business requirements that stick to a Service Level Agreement (SLA) agreed with the mobile operator.
From a MNO’s point of view, a NS is an independent E2E logical network that runs on shared physical infrastructure to provide a negotiated service quality. However, the technology enabling network slicing is transparent to business customers.
For Example, Operators might make a partnership with a 3rd party to provide a network dedicated to the given part which is called Network as a Service “NaaS”.
Why Network Slicing is Essential for 5G?
1- Mobile Network Operators (MNOs) could deploy a single infrastructure network slice type that satisfies the needs of multiple verticals, as well as multiple network slices of different types that are delivered as a single product targeted towards business customers who have multiple and different requirements.
Example: a vehicle may need a high bandwidth slice for infotainment and an ultra-reliable slice for assisted driving).
2- Network Slicing enables Isolation which is essential to guarantee Service Level Agreement (SLA) with a 3rd Party by dedicating network resources for a given service.
Example: MNO can assign dedicated network logical nodes like AMF,SMF, UPF, .. etc for the 3rd party to support resource provisioning.
3- Security can be provisioned per slice, as each slice will have different security requirements. So security strength will be according to slice requirements.
