0  Introductionp. 7

With the recent introduction of a service based management architecture for management of mobile networks [2], a service provider or network operator can manage 5G networks including network slicing, using management services. The next level of management is to manage the communication services provided by the network. The present document studies the use of a service based management architecture for management of communication services.

1  Scopep. 8

The present document specifies potential use cases, requirements and solutions (from the perspective of services based management architecture) for the management of communication services. The document provides conclusions and recommendations on the next steps in the standardization.

2  Referencesp. 8

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.
