8 Data definitions for MDA capabilities

28.1043GPPManagement and orchestrationManagement Data Analytics (MDA)Release 17TS

8.1 Introduction

8.1.1 MDA Types

The output of MDA can be related to a particular capability as described in clause 7, where an MDA type can indicate a specific MDA capability corresponding to a predefined use case(s).

The MDA capabilities may also support analytics of a set of data or analytics for certain PMs, KPIs, trace data, QoE or other type of data. Analytics related to the set of data relies on multiple raw, or already processed input data enabling an MDA MnS producer to provide more complex MDA output. Analytics related to certain set of data including PMs, KPIs, trace or QoE data may rely on these specific categories of data.

MDA MnS consumers may request and obtain output for MDA types related to analytics of a set of data or analytics for certain PMs, KPIs, trace or QoE data.

8.2 About analytics

8.2.1 About enabling data

Analytics are capability-specific, and the present document provides the enabling data for each MDA capability in the respective tables. It is not restrictive or mandatory to use the analytics inputs exactly the same as the provided enabling data for implementation, and other (additional or different) data are also allowed in order to facilitate the production of analytics outputs.

8.2.2 About analytics outputs

For analytics outputs, there are:

1) common information elements that can be generated by MDA and be applicable for all MDA capabilities;

2) capability-specific information elements; and

3) optionally, vendor specific extensions.

The common information elements are provided in clause 8.3, and the capability-specific information elements are provided per MDA capability in clause 8.4 of the present document.

8.3 Common information elements of analytics outputs

8.3.0 General

There are some information elements that are common for all analytics outputs and MDA capabilities, i.e. these common information elements form a subset of all analytics outputs of all MDA capabilities.

8.3.1 Common information element definitions

The common information elements of the analytics outputs are defined in Table 8.3.1-1.
