The “best-effort” service provided by traditional mobile networks can no longer keep up with the diversified requirements of vertical industry applications. These requirements include ultra-low and deterministic latency, mobility, reliability and tenant security isolation. An example is the power system differential protection under the ultra high-reliability and low-latency communication (URLLC) scenario. When a switch command is delivered, the communication between the master and slave differential protection terminals involves electrical vector contrasting and verification of transmission path parameters. The network needs to provide a deterministic delay of 20 ms and a jitter of 600 us or less.
