Modern 5G networks have introduced technologies such as Ultra Reliable Low Latency Communication (URLLC) and Time Sensitive Networking (TSN) support to address a host of time critical networking needs. Time-critical services require the services’ clients and servers across the network to be strictly synchronized, and its underlying communication network to be ultra-reliable and strictly latency-bounded. URLLC and TSN features in 5G will help support an array of use cases spanning across automotive, transportation, healthcare, education, media production, forestry, public safety, banking, utilities and much more.
Support for Time Critical Services over 5G networks have been incorporated in various enhancements in Release 16 and Release 17. The white paper describes how these technologies are impacting legacy networks based on Global Navigation Satellite Systems (GNSS) that have traditionally provided required timing accuracy, as well as the Institute of Electrical and Electronics Engineers IEEE 802.1 TSN standard that is becoming the converged networking technology for factories to enable deterministic and low-latency communication.
“Understanding 5G and Time Critical Services” explores the following key topics:
- Key use cases and requirements
- Technology enablers in 5G Release 16 and 17
- 5G architecture supporting time synchronization, IEEE TSN, and application function (AF) Requested Time Sensitive Communication
- Timing Service resiliency
- Ultra-Reliable Low-Latency Communication
- Time synchronization accuracy and services
- Security of Timing as a Service (TaaS) over 5G
