Abstract: A general mapping method between service requirements and network capabilities is proposed, which can flexibly adapt to service developing requirements through network capability self-organization and service requirement self-mapping. By abstracting and decomposing the capabilities of each layer of the network, a full-dimensional definable network capability model is constructed to realize the opening definition and dynamic evolutionary development of network capabilities from four dimensions, including communication subjects, network functions, network resources, and network security, with more than 30 specific elements. The proposed mapping method "dynamically" selects and combines network capabilities for complex and comprehensive service requirements. Based on the matching degree calculated between service requirements and network capabilities, the optimal combination of network capabilities is selected to reconstruct composite network functions. An intuitive 0-1 mapping matrix form is designed to support mapping realization.
