Study on 5G timing resiliency system
The present document identifies additional potential requirements on the 5G system to support time-synchronization services in public and vertical domains, including both the ability to improve resiliency of timing services involving technologies supported by 5G and the ability to the ability to act as a backup for GNSS timing services.
The use cases address:
• the use of 5G system in concert with other timing technologies as a resilient timing source for end-users in complement/back-up/alternate to GNSS, and
• enhancement to the 5G system to enable time synchronization resiliency if GNSS or other timing services are compromised.
