“…The 3rd Generation Partner Project (3GPP) defines three scenarios for 5G, namely Enhanced Mobile Broadband (EMBB), Massive Machine Type Communication (MMTC), and Ultra-Reliable Low-Latency Communication (URLLC) [2,3]. In order to meet the needs of user experience upgrading and digital-intelligence transformation,5G-Advanced network needs to evolve from the architecture level and technology level.…”

The 5G core network adopts Network Functions Virtualization technology, which forms a variety of virtual resources for general computing, storage, and network hardware to achieve dynamic and flexible deployment of network functions and resources based on needs. With large-scale commercial deployment of cloud-native 5G core network with network function virtualization technology, the operation and maintenance of 5G core network is facing new challenges. This paper describes the architecture and deployment characteristics of 5G core network, and analyses the challenges brought to operation and maintenance by new network characteristics such as SBA, NFV, MEC and separated UPF, as well as the difficulties of operation and maintenance of virtual deployed 5G core network. Combined with the architecture evolution and function enhancement of 5G-Advanced, the architecture and scheme of A Novel Intelligent 5G-Advanced Core Network Operation and Maintenance System are proposed. The architecture and scheme of 5G core network operation and maintenance system construction were proposed, and suggestions on the organizational structure of 5G core network cloud-network integration operation and maintenance were put forward, so as to provide reference for 5G core network cloud-network integration operation and maintenance. The proposed scheme improves the performance of operation and maintenance of 5G core network significantly.

“…In the context of enabling network slicing in 5G networks, there is a myriad of papers that propose architectures or test prototypes based on (i) NFV and/or SDN (see e.g, [35,36,85,86,113,119]), (ii) changes to the RAN protocol stack (see e.g., [48,116,124]), or (iii) using features of the new 5G radio ( [44]) etc. In particular, the work in [29] proposes an architecture to support network slicing in ultra-dense networks, the one in [74] presents an architecture that supports Internet Of Things (IoT) slices whereas the one in [129] dwells on combining 3GPP specifications for 5G with NFV.…”

Infrastructure sharing for mobile networks has been a prolific research topic for more than three decades now. The key driver for Mobile Network Operators to share their network infrastructure is cost reduction. Spectrum sharing is often studied alongside infrastructure sharing although on its own it is a vast research topic outside the scope of this survey. Instead, in this survey we aim to provide a complete picture of infrastructure sharing both over time and in terms of research branches that have stemmed from it such as performance evaluation, resource management etc. We also put an emphasis on the relation between infrastructure sharing and the decoupling of infrastructure from services, wireless network virtualization and multi-tenancy in 5G networks. Such a relation reflects the evolution of infrastructure sharing over time and how it has become a commercial reality in the context of 5G.

“…The NFV network management is different to traditional monolithic network architecture consisting of one Network Management System (NMS) supported by Operational Support System (OSS). On the other hand, NFV network requires several managers and NFV Management and Orchestration (MANO) realise the management part [2]. The three main functional blocks/ Managers of NFV-MANO are: Backhaul is the interface between CU and the 5G Core Network (5G CN).…”

Next generation networks or 5G will be "network of networks" that can support ultra-reliable and low latency communication, high data rate, huge connectivity and high security. Network transformation stirring towards virtualized Radio Access Network (v-RAN) and intelligent resource management are foreseen as key solutions to realise such varied 5G requirements. Effective Radio Resource Management (RRM) is crucial for Mission Critical (MC) services to underpin communication between smartphone, massive machines and tiny sensor devices. The paper explores pioneering research related to architecture and intelligent RRM that helps Service Providers (SPs) to design reference framework of an advanced Radio Link Manager (RLM) enabled by Machine Learning (ML). One example optimization for commercial network/Long Term Evolution (LTE) and some preliminary results are analysed to understand the reference framework. The paper addresses the general reference architecture framework of advanced Radio Link Manager to support Mission Critical services in 5G. The paper also discusses about the ongoing standardisation activities and open source initiatives in 5G RAN.
