5G-ROUTES: D3.1 Report on 5G infrastructure setup for CAM

The objective of 5G-ROUTES project is to conduct 5th generation connected and automated mobility cross-border trials in designated 5G cross-border corridor (“Via Baltica North”). These advanced large scale field trials will take place across 3 EU member state borders (Latvia, Estonia and Finland) in order to validate the latest 5G features and 3GPP specifications under realistic conditions. The aim of these tests is to accelerate the widespread deployment of 5G end-to-end (E2E) interoperable CAM ecosystems and related services in digitized motorways, railways and shipways throughout Europe. The scope of deliverable 3.1 is to describe and summarize the 5G infrastructure setup for CAM in 5G-ROUTES project. This is an intermediate report that will describe the available information at the time of writing this deliverable. Described solution and information could change or can be supplemented over time and the final implemented solution will be described in the version 3.2 of this deliverable. The objective of D3.1 is to describe the 5G trial networks that will be set up by MNO’s for large scale trials in Latvia, Estonia and Finland. It was assumed in the beginning of 5G-ROUTES project that 5G technology has been advanced further and by this time MNO’s have already commercial 5G SA core with commercial 5G SA services available in the region. By the time of writing this deliverable there is no 5G SA core available for commercial services in Latvia, Estonia or Finland. The availability of 5G SA core is essential for carrying out the large scale cross-border trials that are the objectives of 5G-ROUTES project. Situation with currently available 5G services and available frequency resources varies in Latvia, Estonia and Finland. In this task the relevant 5G infrastructure will be installed, configured, and gradually upgraded to the latest 3GPP release. During the trials, in total 11 new 5G base stations are planned to be installed followingly:

• 2 x 5G base stations in Riga (Bikernieki racetrack) for small scale trials with virtual border crossing
• 4 x 5G base stations in Valga/Valka to cover the border crossing for trains and cars and in order to validate the use cases related to autonomous driving, infotainment services and multimodal services involving vehicles and railways
• 4 x 5G base stations in the ports of Muuga and Vuosaari + a small cell 5G base station on the ferry to cover the port areas and the ferry route in between to validate the use-cases related to multimodality, goods tracking and providing uninterrupted connectivity from Tallinn to Helsinki.

The 5G base stations for Telia network mostly on Estonia and Finland sides (except one in Riga) will be supplied, configured and upgraded by EEE and installed by TELIA, and the 5G base stations in Latvia by LMT with the support of their 5G vendor. CTTC will provide an open source 5G platform based on OpenAirInteface to be used in railways as a private 5G network. All 5G base stations will be equipped with MEC functionality, which will be managed and orchestrated by the respective MEAO from EEE. Moreover, a cloud solution and MANO stack will be deployed. The MEC nodes will be connected to each MNOs’ core network and cloud solution. The initial plan is to use also a satellite 5G connectivity via Ku-band geosynchronous and LEO satellites (OneWeb) that will be provided by ADS and which will be integrated with the MNO’s 5G CNs to support handover of PDU sessions without service disruption. This functionality is dependent on 3GPP releases and vendorsupport readiness in the timeframe of 5G-ROUTES project. In addition, E2E eMBB, URLLC and mMTC slices will be deployed across MNO and across satellite – terrestrial 5G domains. The 5G infrastructure will be stand-alone and supporting 3GPP R.16. Initially there was a plan it to support also 3GPP R.17 however it is now clear that REL17 supporting network and end user devices will not be available during the project timeframe.
