Activity Code1D.023
This activity
-
aims at a continued support of the standardisation effort on NTN within the 3GPP.
-
will seek to capitalise on the investments made to date and secure the native integration of satcom within the next generation of mobile networks.
-
encompasses the support to the NTN-related work items recently agreed for Release 18 as well as the preparation of NTN-related items for Release 19 and beyond.
In line with these general objectives, the consortium plans to steer the “3GPP defined NTN standard” towards the most relevant use cases, deployment scenarios and solutions for the European satellite communication eco system while meeting the requirements of user groups (e.g., mobile network operators and verticals) through selected technical contributions and networking activities.
The proposed activity is to support standardisation actions, help develop contributions and advocate positions favourable to the SatCom sector within the 3GPP standardisation process such that they result in tangible industrial opportunities.
Once 3GPP 5G compatible satellite solutions/products are available, the satellite communication industry is expected to benefit from a global eco system and a multi-vendor supply chain.
This project started mid February 2023 and will end mid February 2025, to cover the completion of Rel-18 and the Rel-19. Project detailed objectives are refined after each 3GPP plenaries on a quarterly basis.
