A.5 Management Data Analytics Service (MDAS)

28.5333GPPArchitecture frameworkManagement and orchestrationRelease 17TS

A management data analytics service (MDAS) provides data analytics of different network related parameters including for example load level and/or resource utilisation. For example, the MDAS for a network function (NF) can collect the NF’s load related performance data, e.g. resource usage status of the NF. The analysis of the collected data may provide forecast of resource usage information in a predefined future time. This analysis may also recommend appropriate actions e.g. scaling of resources, admission control, load balancing of traffic, etc.

A MDAS for a NetworkSliceSubnet provides network slice subnet related data analytics. The service may consume the corresponding MDAS of its constituent NFs’. The MDAS for a network slice subnet may further classify or shape the data in different useful categories and analyse them for different network slice subnet management needs (e.g. scaling, admission control of the constituent NFs etc.). If a network slice subnet is composed of multiple other network slice subnets, the MDAS for a network slice subnet acts as a consumer of MDAS of the constituent network slice subnets for further analysis e.g. resource usage prediction, failure prediction for a network slice subnet, etc.

A MDAS for a NetworkSlice instance provides network slice related data analytics. The service may consume the corresponding MDAS of its constituent network slice subnet(s). The network slice MDAS may further classify or shape the data in different useful categories according to different customer needs, e.g. slice load, constituent network slice subnet load, communication service loads. This data can be used for further analysis e.g. resource usage prediction, failure prediction for a network slice, etc.
