Network slicing, the ability of a 5G core network to create virtual private networks, also is related to edge computing, since network slicing moves user plane functions (apps and use cases) towards the edge of the core network.
That applies to the core 5G network itself, as much as any retail slices sold to customers, since the virtualized network itself uses user plane control at the network edge. So one important use case for network slicing is the core operation of the 5G network itself.
As many hope, the ability to create such virtual networks, optimized for different use cases, also will allow greater opportunities for customized use cases with revenue implications for mobile operators using 5G virtualized core networks.
Network slicing therefore has both an internal use case--supporting the operation of the core 5G network itself--as well as third party customer use cases. And many of the expected new use cases are intended for use in business-to-business settings, not consumer use cases, especially where ultra-low latency performance is essential or quite important.
For example, a mobile operator will use a slice of its own to provision core voice services, messaging, consumer and business internet access. Other slices could be ordered up by private network users as well.
