A.1 Analysis of the existing specification capabilities

28.5303GPPConcepts, use cases and requirementsManagement and orchestrationRelease 17TS

Service based management architecture (SBMA) and corresponding MnS are introduced in 5G management architecture in TS 28.533[7], and a different management reference model (i.e. IRP) had been used to manage the network before 5G era in 3GPP TS 32.101[8].

The analysis is based on the following understanding of the existing specification capabilities:

– The management mechanism of LTE supports interface IRP and NRM IRP models.

– The management mechanism of 5G supports MnS which includes MnS component A (Operation/Notification), MnS component B (NRM models) and MnS component C (Alarm/Performance information).

– LTE NRM (with enhancement of YAML or YANG solution set) can be used as MnS component type B and work together with MnS component type A.
