Summary - Y.3168 (12/2025) - Digital twin for network slicing in IMT-2020 networks and beyond

With the development of IMT-2020 networks and beyond, there is the need of a more dynamic network capability to support diverse services. This increases the complexity of network slicing and puts forward higher requirements on the quality of service. Therefore, it is necessary to enhance network slicing mechanisms by digital twin to accurately implement the requirement of real-time resource changes and evaluate network slice performance in advance. Digital twin for network slicing provides a potential solution for addressing higher efficient slicing resource utilization issues.
Recommendation ITU-T Y.3168 specifies the overview, requirements, framework, network function enhancements, procedures and security considerations of the digital twin for network slicing in IMT2020 networks and beyond.
