0  Introductionp. 8

A 5G network is more complex than previous generations of mobile networks, which means that the need for automation is higher for 5G.
This study is evaluating SON functions in previous generations of mobile networks and is studying new SON functions, both for RAN and the core network.

1  Scopep. 9

The present document comprises management use cases, potential requirements and potential solutions of SON for 5G mobile networks.

2  Referencesp. 9

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
  • References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
  • For a specific reference, subsequent revisions do not apply.
  • For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
