Study on vehicle-mounted relays
The present document is the outcome of the study on use cases and potential new requirements for 5GS support of mobile base station relays mounted on vehicles, using 5G NR over the radio links toward UEs and macro RAN (connected to 5GC). This study covers aspects related to:
• Vehicle base station relays providing service to UEs inside the vehicle or in the vicinity of the vehicle;
• End-to-end service continuity during mobility scenarios (including mobility of the relays);
• Provisioning, policies and control, e.g. for
◦ Provisioning of spectrum used by the relays, geographic area restrictions;
◦ Control of relay operation, UEs access and connectivity via relays.
• Aspects related to roaming of relays, security, regulatory requirements (e.g. for emergency services), charging, spectrum interference.
• Gap analysis between the identified requirements and existing 5GS requirements or functionalities.
