Network Functions Virtualization technology allows for easier creation and expansion of separate logical nodes and functions for a specified group of traffic and signaling, often referred to as a network slice. In turn, network slicing opens up a new way of achieving in-service software management at the network level.

With network slicing, a parallel network can be set up with a new software version of network functionality, followed by step-by-step migration of sessions – lowering the risk for the operator and ensuring minimal disruption to subscribers. As a result, it enables more efficient business models for operators while simplifying software architecture requirements, including software upgrades, on network elements such as MME, SGW and PGW.
