5g Core Network Architecture

One of the main improvement and innovation that will happen in 5g is the cloud native architecture of core network.

5g core network architecture.

5g standalone means everything is from 5g. Authentication server function ausf core access and mobility management function amf data network dn e g. As shown in the figure 5 the 5g mastercore is convergence point for the other technologies which have their own impact on existing wireless network. The 5g core will be the heart of the network and acts as an anchor point for multi access technologies.

Certainly 5g looks very promising in terms of parameters like high bandwidth high capacity high speed low ultra low latency high density coverage high availability low device energy. With software defined networking sdn and network functions virtualization nfv supporting the underlying physical infrastructure 5g comprehensively cloudifies access transport and core networks. 3gpp has defined a new 5g core architecture that supports service delivery over wireless fixed or converged networks. 5g is providing connectivity and services to consumers enterprises and things devices machines sensors etc.

The 5g system architecture consists of the following network functions nf majority of which constitute the 5gc. 5g architecture 5g architecture 3gpp. Services are provided via a common framework to network functions that are permitted to make use. We are witnessing floods of information on potential 5g services use cases implementations and its impact across different verticals.

This will take time. The ng ran for sa architecture connects to the 5gc network using the ng interface. 5g core network architecture a beginners guide. 5g is also a technology transformation for operators striving for more flexibility and speed in network deployment and with an expectation of being able to address new business opportunities with use cases beyond mobile broadband mbb.

For a successful 5g launch the operator needs to secure a network that includes end to end e2e capabilities aligned across devices ran core and management systems. The 5g core network architecture is at the heart of the new 5g specification and enables the. In the sa architecture the nr base station logical node gnb connects each other via the xn interface. It needs to deliver a seamless service experience across fixed and wireless access technologies.

Interestingly its design facilitates mastercore to get operated into parallel multimode including all ip network mode and 5g network mode. In short 5g core is a fundamental piece of the 5g network to enhance end user experience simplify operations add service agility and improve network capabilities all thanks to its future proof network architecture. The service driven 5g network architecture aims to flexibly and efficiently meet diversified mobile service requirements. Services and functions will work as microservices containers and vms.

Operator services internet access or 3rd party services.
