摘要
针对未来6G网络场景多样化、网络要素多元化等带来的网络架构设计和部署复杂度升高的难题,提出了一种基于数字孪生的6G网络架构建模、评估及优化方法.首先,对网络架构中的复杂要素进行系统分类,据此在数字孪生空间内建立包含业务域、逻辑域和物理域的三域模型;其次,利用超图理论对模型中的各域及其之间的复杂关系进行详细建模;再次,提出了网络架构熵的概念,并将其用于量化评估6G网络架构设计和部署方案的合理性;最后,提出了一种6G网络架构熵的构建方法,推导并形成了6G网络架构熵减的设计思路.仿真结果表明,所提架构熵减理论能够在不同场景下针对6G网络架构的设计和部署方案优劣进行量化评估,并给出优化设计的方向.
Abstract
Facing the challenges of increased complexity in 6G network architecture design and deployment due to di-verse network scenarios and the pluralization of network elements,a digital twin-based method for modeling,evaluating,and optimizing the 6G network architecture was proposed.Initially,the intricate elements in the network architecture were systematically categorized,leading to the establishment of a three-domain model comprising service,logical,and physical domains in the digital twin space.Subsequently,the three domains and their intricate relationships were mod-eled in detail using hypergraph theory.Furthermore,the concept of network architectural entropy was introduced to quan-titatively assess the rationality of the design and deployment scheme of the 6G network architecture.Finally,a method for constructing 6G network architectural entropy was proposed,and the design idea of 6G network architecture entropy reduction was developed and formulated.Simulation results demonstrate that the proposed architecture entropy reduction theory can quantitatively evaluate the pros and cons of 6G network architecture design and deployment schemes in vari-ous scenarios and offer optimal design guidance.
