A Network Slice is a complete logical network including Radio Access Network (RAN) and Core Network (CN). It provides telecommunication services and network capabilities which can vary from slice to slice. A device can access multiple Network Slices simultaneously through a single RAN.
Network Slicing is defined as the method of creating multiple unique logical and virtualized networks over a common multi domain infrastructure. In 5G Core, service providers offer multiple types of communications services as follows:
- Business-to-consumer (B2C) services. For example, mobile web browsing, 5G voice, Rich Communication Services, and so on.
- Business-to-business (B2B) services. For example, internet access and LAN interconnection.
- Business-to-household (B2H) services. For example, Internet access, MBMS, VOIP, and VPN.
- Business-to-business (B2B2X) services. For example, services offered to other CSPs such as international roaming and RAN sharing communication services to their own customers.
