5G NR (New Radio) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. Nupf: Service Based Interface for N4 PCE: Path Computation Entity SMP: Service Messaging Platform SR: Service Router UPS: User Plane Services . In this new architecture each Network Function (NF) offers one or more services to other NFs via Application Programming Interfaces (API). New antennas will incorporate technology known as massive MIMO (multiple input, multiple output), which enables multiple transmitters and receivers to transfer more data at the same time. 5G Core Architecture models. 5G E-UTRAN New Radio Dual Connectivity (EN-DC) architecture is the leading 5G architecture for the support of the initial 5G Enhanced Mobile Broadband (eMBB) services. Laut 3GPP nutzt das 5G-Core-Netz eine cloudorientierte, servicebasierte Architektur (SBA), die alle Funktionen und Interaktionen von 5G, einschließlich Authentifikation, Sicherheit, Sitzungsmanagement und Aggregation des Verkehrs von den Endgeräten, … The logical 4G/5G RAN architecture. Reply. 5G by its nature spans many domains beyond mobility and requires a transformation unseen so far. This architecture of 5G satellite segment is … The transport network layer is built on IP transport and GTP-U is used on top of UDP/IP to carry the user plane PDUs between the NG-RAN node and the UPF. 5G services will once again be IMS based, but using a new Quality of Service Architecture. 5G could be a totally a new thing at the radio resource access layer or it could be again evolution from LTE advanced 4G. The N1, N2 and N3 5G reference interfaces are mandatory requirements on an AGF implementation, along with the V (or Va) interface to the wireline access network (wAN), defined within BBF’s TR-178 - Multi-service Broadband Network Architecture and Nodal Requirements. Appearing in the second specification iteration of 5G, or release 16 in 3GPP parlance, the Service Communication Proxy (SCP) was defined within TS23.501 - System architecture for the 5G System. The 5G network functional application platform interface (5G nFAPI) is an initiative that extends for 5G the functional split between the MAC and PHY functions that enables virtualization of the MAC function, as identified by the study undertaken by the Small Cell Forum; this virtualization is already enabled for 4G via 4G-nFAPI. The NG user plane interface (NG-U) is defined between the NG-RAN node and the UPF. 5G network FAPI specifications . And it can be hard at the best of times to navigate this new and complex reality. Research paper. It’s the sort of function that is born of necessity. Carriers around the globe are now pushing forward with 5G deployments. In principle, there are no significant differences regarding protocols and interfaces to the standard LTE architecture, since S1 and X2 interfaces are used. This article provides a comprehensive overview of the 5G RAN design guidelines, key design considerations, and functional innovations as identified and developed by key players in the field. In this whitepaper, we will take a closer look at the new virtualized 5G RAN, the O-RAN Alliance architecture and open fronthaul interfaces as well as an overview of the O-RAN O-RU whitebox solution. Mar, 2019 by Pankaj in 5G, NG Interface, NG-C, NG-U. This CU/DU split will help to adopt a flexible architecture with various deployment scenarios, meet 5G latency demands, and reduce the overall fronthaul capacity needs. Prabhatkumar Durgesh says: February 9, 2020 at 5:14 am nice article. 10 British Telecommunications plc 2017 Latency requirements DUAAU IPSec CU F2 interface … 5G services will increasingly depend on Precision Time Protocol (PTP) for resiliency and deterministic timing throughout the network. 5G radio access network architecture – design guidelines and key considerations. We will also cover 5G deployment scenarios from the specs as well as some of the informative web resources. Now one of the popular interfaces in 5G RAN is between RU and DU in 5G fronthaul architecture. Reply. 5G Virtual RAN overview. Architecture 5G base station gNB with F1-satellite interface. The interface towards billing systems is still based on the legacy ASN.1 syntax and has not been updated to the new Service Based Architecture, only the new information needed to support 5G charging. on N3/N9 interface) are delivered to the application stack over the same RX queue and processed by the same application thread bound to the CPU core ensuring packet buffers and flow-related control structures are not shared between cores. - Identify high-level requirements or guidelines on Service-based architecture design in 5G including network function, interface/protocol, API design principle; - Investigate how operators can leverage Service-based architecture in 5G in the best way, e.g., customized network slicing, updating and managing network feature dynamically. 3GPP specified and presents both versions of 5G system architectures: Reference Point System Architecture; Service Based System Architecture ; A reference point representation, shows the interaction exist between network elements by point-to-point reference point. Keywords: 5G, REST, application programming interfaces, 3GPP, service based architecture, SBA, northboundAPIs, NAPS, HTTP. prasanna says: February 12, 2020 at 12:41 pm Thanks. Chapter 6 Radio-Interface Architecture Abstract This chapter described the overall NR architecture. Die 5G-Core-Netzwerkarchitektur ist das Herzstück der neuen 5G-Spezifikation und ermöglicht den von 5G geforderten höheren Durchsatz. Reply. The 5G Architecture Working Group as part of the 5GPPP Initiative is looking at capturing novel trends and key technological enablers for the realization of the 5G architecture. It is like a point-point interface between two network elements e.g. RU and DU functions are described as below. According to 3GPP TR38.801, the typical baseband (BBU) unit of LTE, in 5G NR is now split into the Central Unit (CU), and the Distributed Unit (DU). 5G Fronthaul Architecture | Time Sensitive Networking. Compared to previous generations the 3GPP 5G system architecture is service based. 5G PPP Architecture Working Group View on 5G Architecture Version for public consultation, updated version available on July 1st 2016 Page 5 / 60 MEF Metro Ethernet Forum MSMP Multi-Service Management Plane NGFI Next Generation Radio Interface NG-PON2 Next Generation PON Technology based on WDM and TDMA It was designed to be the global standard for the air interface of 5G networks. The external interfaces of the RAN domain (except to the OSS) are standardized under 3GPP, as is the functional behavior of the RAN domain as a whole. The new 5GC architecture called as Service-Based Architecture (SBA), is built using IT network principles and cloud native technology. As Open RAN architectures gain momentum and are adopted for 5G deployments, the PTP timing flows will be terminated in the 5G radios and the DU is no longer required to be part of the timing chain form the Grandmaster Clock to the 5G radio. 5G Radio Research #NAP #RAN #5gradioaccess #5gnetworks. 5G New Radio (5G NR) is a completely new air interface being developed for 5G.
