Previous network generations’ main aim was to provide customers with reliable and fast mobile data services. 5G has widened this scope to provide a broad range of services offered to users across various platforms and multi-layer networks. 

As far as the 5G network design is concerned, it is highly advanced and a little complicated. The 5G network architecture network elements are characteristically raised to pay for a new condition. Similarly, service providers can execute advanced technology to acquire value-added benefits easily. 

Additionally, 5G develops a coherent, dynamic, and flexible network of various advanced technologies to support several applications. 5G uses the most intelligent architecture, with RANs (Radio Access Networks) no longer constrained by ground station proximity or complicated infrastructure. This 5G leads towards flexible, disaggregated, and virtual RAN with modern interface developing more data access points.

5G Core Architecture

The 5G network architecture is at the centre of the current 5G specification and facilitates the enhanced demands that should be supported by 5G. The recent 5G core, as described by 3GPP, uses cloud-aligned SBA (Service based Architecture) that stretches across the functions and interaction of 5G, including security, authentication, session administration, and traffic aggregation from all end devices. The 5G foundation accentuates NFV with virtualised software processes deployed utilising the MEC infrastructure prominent to 5G architectural principles. 

Differences from 4G Architecture

Changes and modifications at the more stage are among the numerous architectural changes and improvements that support a shift from 4G to 5G, encompassing a migration to massive MIMO, millimetre wave, network slicing,  and, critically, each element of this diverse ecosystem of 5G. The 4G EPC (Evolved Packet Core) is considerably distinct from the core of 5G, with the 5G core leveraging virtualisation and a design of cloud-native software at remarkable stages.

Among other modifications and changes that differ the core of 5G from its predecessor, 4G are the UPF (User Plan Function) to decouple the control of packet gateway and functions of the user plane, and AMF (access and mobility management function ) to separate session management processes from various connection and mobility supervision tasks.   

5G Architecture Options

Various well-orchestrated plans and incremental steps are needed to fill the gap between 5G and 5G. Emblematic of such change is the continuous and slow transition from non-standalone mode to an option of a standalone method of 5G architecture. During the late 1970s, the 5G non-standalone was confirmed and uses prevailing LTE RAN and various heart networks as an anchor, with an addition of a carrier of  5G elements. Despite dependency on 4G architecture, the non -standalone mode enhances its bandwidth by tapping into millimetre wave frequencies. 

The standalone 5G mode is critical for 5G deployment from the surface up to the recent core architecture and full deployment of all features, hardware, and functionality of 5G. As non-standalone mode slowly provides a way to a modern 5G mobile network architecture deployments, good, careful execution and planning should make this change seamless for the customer base.
