• Description:
• Tenders are invited for 5g New Radio (Nr) Non-Terrestrial Networks Control Plane Demonstrator for Ngso Constellations - Expro plus (Artes 4.0 Spl 5g/6g 3a.181) The objective of this activity is to analyse the control plane procedures and signalling in 5G New Radio (NR) standard and adapt itto the peculiarities of Non-Terrestrial Networks (NTN) based on Non-Geo Stationary Satellite Systems and test it via a demonstrator.Targeted Improvements: New capability related to the design of 5G NTN control plane not existing today in ESA member states.Description:In recent years, several players from both satellite and terrestrial mobile networking industry are looking with interest at the Non-Terrestrial Technology for providing 5G services in sparsely populated areas. For the first time in 3GPP history, satellite technology falling under the Non-Terrestrial Technology classification - is formally part of the specification. New Radio services are the big enhancement introduced by 5G, and they are aimed to providing very high data connections.In such service, User Equipment is provided with an antenna which is directive and even more directive if the NR service has to be provided via satellite. Adaptations to the control plane of the 5G NR standard are required for its development on satellite networks, where a User Equipment needs to point to a given satellite which is not necessarily known a priori. A long list of procedures registration, handover, etc. - become therefore nontrivial if based on the terrestrial networks' procedures. This adaptation requires a review of both the satellite architecture and the signalling mechanisms of the New Radio specification. As an example, one could foresee a small channel transmitted on a global beam by each satellite including the information about which satellite is to be used by the UE to register depending on its location and at the same time the NR standard to be updated introducing a new System Information table definingsuch information.The activity shall therefore define the control plane of 5G New Radio standard for NTN networks and demonstrate its performance in a software demonstrator. The main engineering tasks required in this activity are:1) review of the 5G NR control plane procedures and signalling 2;2) Definition of a reference NTN architecture based on Non-Geo Stationary Orbits;3) identifying possible strategies for satellite networks to implement a control plane as close as possible to the current specification;4) identifying required modification to the current specification for having a control plane fit to be deployed on Non-Terrestrial Networks;5) demonstrate such architectures and control plane design in a software demonstrator
