1  Scopep. 8

The scope of the present document is:
  • to identify the main key issues associated with business roles, service and network management and orchestration of a 5G network with integrated satellite component(s) (whether as NG-RAN or non-3GPP access, or for transport), and
  • to study the associated solutions.
The present document aims at minimising the impacts and complexity of satellite integration in the existing business models and in management and orchestration aspects of the current 5G networks.

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.

3.1  Termsp. 8

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Geostationary (GEO) satellites:
located precisely in the plane of the Equator at an altitude of 35,786 km, these satellites rotate at the same rate as the Earth's rotation.
Highly-Eccentric Orbiting (HEO) satellites:
satellites with a range of operational altitudes between 7,000 km and more than 45,000 km.
Low-Earth Orbiting (LEO) satellites:
satellites typically deployed in constellations with altitude ranging from 500 km to 2,000 km.
Medium-Earth Orbiting (MEO) satellites:
with altitude ranging from 8,000 to 20,000 km.
Non-Geostationary Orbiting (NGSO) satellites:
These satellites do not stand still with respect to Earth.
