5G Core

Build a cloud-native 5G Core that connects everyone and everything

Nokia is leading the journey to the 5G Core with cloud-native products and solutions that that support rapid and cost-effective service deployment across a range of access technologies.

Our 5G Core portfolio enables you to address increasing demand for services that connect everyone and everything. It can help you build an agile, cognitive, sensing, self-learning and programmable network that pushes the boundaries of technology to revolutionize and transform the way people live, work and interact.

Defining a new 5G Core

5G has demanding service and network requirements that will require a fundamental change to the core architecture. The 5G Core will be the heart of the network and acts as an anchor point for multi-access technologies. It needs to deliver a seamless service experience across fixed and wireless access technologies.

3GPP has defined a new 5G Core architecture that supports service delivery over wireless, fixed or converged networks. This new 5G Core uses a cloud-aligned Service-Based Architecture (SBA) that supports control plane function interaction, reusability, flexible connections and service discovery that spans all functions.
