Summary: A Network Digital Twin (NDT) is a high-fidelity digital replica of a real network, particularly the Radio Access Network (RAN). It is used for testing configurations and algorithms, as well as predicting their performance. This paper proposes an NDT architecture for the RAN, introduces a framework aligned with O-RAN specifications, and demonstrates the successful training of an RL-based capacity-sharing solution.

Summary: Packet-optical xHaul transport networks offer a promising solution for low-cost connectivity in dense 5G radio access networks. By using optical add-drop multiplexers (OADMs), the demand for fiber connections can be reduced. This study focuses on planning a survivable 5G packet-optical xHaul access network, where remote sites are connected to a central hub through disjoint primary-backup paths. The proposed solution achieves network survivability using a dedicated path protection with wavelength aggregation (DPPWA) mechanism.

Summary: The Internet of Things (IoTs) has become a crucial part of the 5th Generation (5G) network, accelerating the transition to a digital society. However, the increasing signaling traffic generated by billions of IoT devices has strained the 5G Core network (5GC) control plane. To address this issue, the 3rd Generation Partnership Project (3GPP) proposed a Service-Based Architecture (SBA) for a flexible and scalable cloud-native 5GC. This paper introduces a Message-Level StateLess Design (ML-SLD) to provide a cloud-native 5GC from an architectural standpoint, including innovative mechanisms for servitization and on-demand message forwarding.

Summary: Virtual Radio Access Network (vRAN) is crucial in today's mobile edge system, but the existing data arrangement processes cannot efficiently utilize modern processor ports, resulting in performance bottlenecks and inadequate memory bandwidth utilization. To tackle this issue, we propose an Arithmetic Ports Consciousness Mechanism (APCM) that eliminates bottlenecks and improves memory bandwidth utilization by utilizing idle ports.

Summary: This paper investigates the planning process for a 5G radio access network with the aim of determining the minimum number and locations of MRRUs and mRRUs in a given geographical area to meet user demand and coverage constraints. The proposed two-step approach involves optimizing RRU locations with a low complexity meta-heuristic algorithm and then removing redundant cells through an iterative elimination method to achieve over 98% coverage and less than 2% cell capacity outage rate.
