A.7 Utilization of management data analytics services

28.5333GPPArchitecture frameworkManagement and orchestrationRelease 17TS

A management data analytics service (MDAS) provides data analytics for the network. MDAS can be deployed at different levels, for example, at domain level (e.g. RAN, CN, network slice subnet) or in a centralized manner (e.g. in a PLMN level). A domain-level MDAS provides domain specific analytics, e.g. resource usage prediction in a CN or failure prediction in a network slice subnet, etc. A centralized MDAS can provide end-to-end or cross-domain analytics service, e.g. resource usage or failure prediction in an network slice, optimal CN node placement for ensuring lowest latency in the connected RAN, etc. Figure A.7.1 illustrates an example of deployment model of the MDAS:

– Domain MDAF produces Domain MDAS

– Domain MDAS is consumed by the Centralized MDAF and the other authorized MDAS Consumers (for example, infrastructure manager, network manager, network slice manager, network slice subnet manager, other 3rd party OSS, etc.)

– Centralized MDAF produces Centralized MDAS

– Centralized MDAS is consumed by different authorized MDAS Consumers
