1st presentation Title: “5G-GOVSATCOM Project for the Integration of Terrestrial and Satellite 5G Systems” Presenters: Miguel Ángel Vázquez (CTTC, Spain), Marc Carrascosa Zamacois (CTTC, Spain), Giovanni Giambene (UNISI, Italy) Abstract: The EU EUSPA agency has financed the GOVSATCOM program, whose aim is to support the development of a 5G NTN key infrastructure in Europe for crisis management and surveillance tasks. In the long term, the EU-GOVSATCOM system will be able to use the new IRIS2 satellite constellation, whose consortium has been set in December 2024. The standardization of NTN as an integral part of 5G systems is progressing, with important progress made in the last Releases 17 and 18, especially at the PHY layer. The 3GPP work towards the TN-NTN integration is still needed to achieve a complete protocol integration. Within the GOVSATCOM framework, the EU 5G-GOVSATCOM project deals with TN-NTN integration for the support of seamless mission-critical (MCX) services. The first part of this presentation deals with the envisaged system architecture; then the second part addresses the design issue of the novel UE terminal; finally, the last part of this presentation addresses the issue of the seamless Vertical Handover (VHO) between TN and NTN, proposing the adoption of a smart gateway server to manage a seamless switch from the two networks when some critical conditions are met or according to defined policies. The use of VPNs between smart gateway entities through the TN and NTN enables VHO execution at the network layer transparently to the MCX end-to-end service.
