Enhancement of 3GPP management system for multiple tenant environment support
Zhu, Lei, Huawei
Summary based on the input provided by Huawei Tech in SP-200526.
The work item on enhancement of 3GPP management system for multiple tenant environment support has concluded conceptual descriptions, specific information for tenant and other potential changes to management services. This release 16 work item is a feature to enhance management and orchestration to 5G network and network slicing. This is also a follow up work item to study on tenancy concept in 5G networks and network slicing management, which concluded to enhance management system as following:
– Conception description
– Performance measurement in multiple tenant environment
– Network slice fault supervision in multiple tenant environment
In 3GPP management system, tenant is type of communication service consumer and tenant represents a group of MnS consumers associated with the management capabilities they are allowed to access and consume. The 3GPP management system provides multi-tenancy support, by associating different tenants with different sets of management capabilities. Every tenant may be authorized to access and consume those MnSs that the operator makes available to this tenant based on SLA.
The MnS consumer, acting on behalf of a tenant, may get the performance measurements of a network slice. Performance measurements specified in TS 28.552 can be split into sub-counters per S-NSSAI. 3GPP management system can use these sub-counters to distinguish performance measurements for different tenants, which might be required when performance measurements are exposed as part of Network Slice as a Service (NSaaS) specified in TS 28.530.
