4 Concepts and overview
4.1 Overview
The 5G networks and network slicing are designed to support eMBB, URLLC and mIoT services. Some services have
ultra-low latency, high data capacity, and strict reliability requirements, as any faults or performance issues in the
networks can cause service failure which may result in property damage and body injury. Therefore, it is necessary to
collect real-time performance data that can be used by analytic applications (e.g., network optimization, SON, etc.) to
detect the potential issues in advance, and take appropriate actions to prevent or mitigate the issues. Also, the
performance data shall be able to be consumed by multiple analytic applications with specific purposes.
4.2 Management data analytics
The raw performance data of NFs of the mobile network can be analysed, together with other management data (e.g.,
alarm information, configuration data),and formed into one or more management analytical data for NFs, sub-networks,
NSSIs or NSIs. The management analytical data can be used to diagnose ongoing issues impacting the performance of
the mobile network and predict any potential issues (e.g., potential failure and/or performance degradation). For
example, the analysis of NSI/NSSI resource usage can form a management analytical data indicating whether a certain
resource is deteriorating. The analysis and correlation of the overall performance data of mobile network may indicate
overload situation and potential failure(s).
SON Capacity and Coverage Optimization (CCO) is one typical case that may consume the management analytical
data. CCO provides optimal coverage and capacity for the E-UTRAN, see clause 4.5 of TS 28.628 [13], which may also
be applicable for 5G radio networks. The management analytical data related to coverage and capacity help the SON
CCO to realise the situation of coverage and capacity or interference, and to trigger corresponding optimization if
needed.
NOTE: Details of the management analytical data including e.g. format, categorisation and method/algorithm of
calculations are to be defined.
