Network Architecture in the 6G/IOWN Era: Inclusive Core

In the era of the 6th-generation mobile communication system (6G) and Innovative Optical and Wireless Network (IOWN), it is assumed that four facets of convergence and coordination, namely, cyber space and physical space, computing and network, analog and digital, and mobile communication and fixed communication, will advance as communication services or the environment changes.This multifaceted convergence and coordination increases the need for end-to-end and seamless coordination of information processing and distribution across terminals, devices, networks, and applications.In this article, we introduce our research and development efforts in a network architecture for the 6G/IOWN era called the Inclusive Core, which is the foundation platform for achieving this multifaceted convergence and coordination.
