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.
- 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.
Network Slice Discovery and Monitoring
Network Slice leverages 5G Core and vRAN Assurance to provide discovery and monitoring at the component level. Network Slice and its subnet instances are discovered in VMware Telco Cloud Service Assurance Domain Manager (ESM) using VMware Telco Cloud Automation REST APIs.
vRAN and CNFs can monitor and provide root cause analysis on a Network Slice. For Topology, Notification, and RCA information, see Virtualized Radio Access Network use case in the VMware Telco Cloud Service Assuarance User Guide.
For the Network Slice to be discovered, the VMware vROps and the VMware Telco Cloud Automation instance (where the Network Slices are configured) must be discovered in the VMware Telco Cloud Service Assurance.
Once the discovery is complete, the CellSite Group, CellSite, and its association with the Hypervisor will be created in the VMware Telco Cloud Service Assurance. The real time monitoring of the Cell Sites, Kubernetes nodes, and the node pools takes place every polling interval post the discovery.
Perform the following tasks to discover and monitor Network Slice.
