It offers distributed cloud, NFV (Network functions virtualization) and SDN (Software Defined Networking). It offers many functions including network slicing to serve vivid customer requirements. A gNB-CU and a gNB-DU is connected via F1 interface.ĥGC (5G Core) Network architecture is highly flexible, modular and scalable. gNBs can be interconnected through the Xn interface.Ī gNB may consist of a gNB-CU and one or more gNB-DU(s). The NG-RAN consists of a set of gNBs connected to the 5GC through the NG interface.Īn gNB can support FDD mode, TDD mode or dual mode operation. The mechanism for transparent transfer of NAS messages is also included. Various aspects which includes requesting the service, controlling different transmission resources, handover etc. User plane protocols implement actual PDU Session service which carries user data through the access stratum.Ĭontrol plane protocols control PDU Sessions and connection between UE and the network from The protocols over Uu and NG interfaces are categorized into user plane protocols and 5G smartphones interact with 5G-RAN over Uu radio interface.ĥG RAN interacts with 5GC (5G Core Network).

The same have been depicted in the following figure-3 and figure-4. Here AMF stands for Access and Mobility Management Function and UPF stands for User Plane Function.ģGPP TS 38.401 describes 5G NR user plane and control plane as well as 5G NR RAN architecture with various interfaces (NG, Xn and F1) and their interaction with the radio interface (Uu). LTE) user plane and control plane protocol terminations towards the UE,Īnd connected via the NG interface to the 5GC. Smartphone, tablet, laptop etc.) and it is connected via the NG interface to the 5GC. This is as defined in the 3GPP TS 38.300 specification.Īs shown in the figure, gNB node provides NR user plane and control plane protocol terminations towards the UE (i.e. ĥG NR overall architecture is shown in the following figure-2.Global content service providers support following applications: Their files from any computer across the globe with the use of internet. It allows consumers to use applications without any installation and access It consists of nanotechnology, cloud computing, All IP architecture.Ĭloud computing utilizes internet as well as central remote servers to maintain data and applications It also minimizes latency.ĥG aggregator aggregates all the RAN traffics and route it to gateway.ĥG aggregator is located at BSC/RNC place.ĥG mobile terminal houses different radio interfaces for each RAT in order to provide support forĪll the spectrum access and wireless technologies.Īnother component in the 5G network architecture is 5G nanocore. This architecture reduces number of network elements in data pathĪnd hence reduces cost to greater extent.

WiMAX, WiFi, CDMA2000, EV-DO, CDMA One, IS-95 etc.įlat IP architecture identify devices using symbolic names unlike hierarchical architecture where in RANs supported by 5G architecture are GSM, GPRS/EDGE, UMTS, LTE, LTE-advanced, As shown 5G network uses flat IP concept so thatĭifferent RANs (Radio Access Networks) can use the same single Nanocore for communication.

2017 is also described.įigure-1 depicts 5G network architecture.

network elements.ĥG NR (New Radio) architecture as per 3GPP document published in dec. The 5G architecture consists of all RANs, aggregator, IP network, nanocore etc. This page describes 5G network architecture with its elements. 5G network architecture | 5G Architecture
