Network data analytics for OAM
A method performed by an operations administration and management (OAM) apparatus includes acting as a Management Data Analytics Function (MDAF) in a network. The network includes a plurality of network functions (NFs). Acting as the MDAF includes: collecting management data and network data from the network, analysing the management data and the network data, and providing a receiving entity with management data analytics service information based on the analysis of the management data and the network data.
1. A method performed by a Management Data Analytics Function (MDAF) node in an operations administration and management (OAM) network, the method comprising:
collecting network management data to be analyzed by the MDAF node, from a first network node connected via a service-based architecture in a 3rd Generation Partnership Project (3GPP) network;
analyzing the network management data; and
providing a second network node connected via the service-based architecture in the 3GPP network, with management data analytics service information based on the analyzing the network management data,
wherein at least one of the first network node and the second network node is a Network Data Analytics Function (NWDAF) node for analyzing network data in the 3GPP network.
2. A Management Data Analytics Function (MDAF) node in an operations administration and management (OAM) network, the MDAF node comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
collect network management data to be analyzed by the MDAF node, from a first network node connected via a service-based architecture in a 3rd Generation Partnership Project (3GPP) network,
analyze the network management data, and
provide a second network node connected via the service-based architecture in a 3GPP network, with management data analytics service information based on the analysis of the network management data,
wherein at least one of the first network node and the second network node is a Network Data Analytics Function (NWDAF) node for analyzing network data in the 3GPP network.
3. The method according to claim 1 , wherein the management data analytics service information is provided to a self-organizing network (SON) function, a network management system (NMS), a network slice management function (NSMF), a network slice subnet management function (NSSMF), network performance and service assurance management and orchestration entities, an operation support system (OSS), and a business support system (BSS).
4. The method according to claim 1 , wherein the network management data includes network slice-specific information.
5. The method according to claim 1 , wherein the at least one of the first network node or the second network node includes the NWDAF.
6. The method according to claim 1 , further comprising:
interacting with the NWDAF node leveraging the management data analytics service information for controlling another network node in the 3GPP network.
