5G Standalone Seamless Roaming for Cross-Border Automotive Use Cases
—5G and beyond 5G networks are designed to enable a set of novel applications and industry verticals with very different requirements, such as agriculture, transport, or healthcare. For example, to support automotive and teleoperated transport, 5G systems are expected to guarantee URLLC (Ultra Reliable Low Latency Communications) requirements with minimal interruption times. The 5G-Blueprint project aims to provide technical solutions for 5G-enabled uninterrupted (i.e., seamless) communications in cross-border teleoperated automotive use cases. To support these services, this poster presents, to the best of our knowledge, the first practical implementation of seamless 5G Standalone Roaming using off-the-shelf UEs and gNBs. Preliminary results of our experiments show an interruption time in the range of 100-150 milliseconds, thereby meeting the requirements of teleoperated automotive services.
