Summary:
|
With the development of IMT-2020 network and beyond, more and more service scenarios and requirements are emerging, which increases the complexity of network slicing and puts forward higher demands on the quality of service. The existing network slicing mechanisms are difficult to accurately satisfy the demand of real-time resource changes and evaluate slice performance in advance.
Digital twin can be used construct a digital twin network(DTN) as a virtual representation of the physical network, and can integrate all existing data to create an accurate digital network simulation in real time. DTN has the advantages of strong visualization, high real-time performance, and high simulation accuracy, which makes it a potential solution for addressing high efficient resource utilization issues. User environments and network slicing can be simulated by digital twin network, so as to optimally perform network resources allocation for various network slicing. The digital twin function designs a network resource allocation plan and simulates the network of slice allocation, which couldsatisfy the customer's requirements Therefore, it is necessary to enhance network slicing capabilities with digital twin in IMT-2020 networks and beyond.
This Recommendation specifies the overview, requirements, framework, network function enhancements, procedures and security considerations of digital twin for network slicing in IMT-2020 networks and beyond.
