It consists of data-driven network intelligence that helps in optimizing the usage of networkresources.It uses a C/U plane architecture with the help of a radio network (RN)[ CITATION Ish12 \l1033 ].For the coverage and capacity, it has altered frequency bands.It has the concept of nesting and relaying for Nomadic hotspots that also support multipledevices.It creates Asynchronous access to MTC devices with the help of new waveforms thatinclude contention-based access.Helps in the scaling of the functions of cloud networks with dynamic deployment.
Scaling of network functions and network deploymentNetwork deployment and scaling of network function are done with SDN and NFV networking. Inthe network cloud, CPE and UPE functions are quickly deployed and it is scaled and orchestratedon demand. By simply with the additional instances of prerequisite software, all the resources basedon data centers can be quickly shifted to familiar apps. Flexibility in the network can be achievedwith a cloud infrastructure considering its raw processing capacity. Infrastructure-as-a-service alsois known as IaaS helps in renting the additional resources of Spare cloud when the demand is low.In short, with the SDN and NFV networking technologies helps in achieving faster, easier andcheaper networks for the management and deployment.[ CITATION Kis13 \l 1033 ]Network LayersThe architecture of network layers has two logical layers known as a radio network layers and acloud network layer. The radio network consists of a minimum set for L1/L2 functions performedby different base stations. Whereas a cloud network layer consists of a U-plane and C-plane entities(UPE & CPE). These planes help in performing more consistently with higher layerfunctions[ CITATION Lar13 \l 1033 \m Kis13].This kind of architecture of the network layers makes things easier for the network itself and moreflexible deployment. It can reduce different functionalities as it benefits base stations to consumeless energy and perform more sufficiently[ CITATION Gol09 \l 1033 ].C/U-plane split architectureThe main function of a C/U plane split architecture enables capacity and network coverageindependently with the help of the radio network[ CITATION Ish12 \l 1033 ]. By using thespectrum through low-frequency bands, Metro and Macro base stations deliver coverage in cellsites. To boost its capacity, advanced schemes are also implemented.Since the traffic and high flexible users are distributed in small cells, advance schemes can beswitched off or they are put to sleep to save energy that results in high network performance. TheC/U plane separates the coverage portion that helps in areas overlapping macro coverage into thebase stations of small cells. It also helps in connecting multiple base stations at the same time.Identification and Analysis of 5G attacksThe 5G wireless network is all about its high data rates, large coverage with the help of dense basestations, extremely low latency and providing a better quality of service (QoS). With all thesebenefits, it requires more security to not only ensure the safety of its critical infrastructure but alsothe safety of the fifth generation society[ CITATION Fet12 \l 1033 ].
