Evolve your core network for 5G

5G Core (5GC)

Get to the core of 5G – a cloud native dual-mode 5G Core that combines EPC and 5GC network functions into a common cloud native platform for efficient TCO and smooth migration to 5G.

You’ve probably heard about advanced 5G use cases which, thanks to ultra-low network latency and very high throughputs, will revolutionize businesses and the day-to-day lives of consumers. But none of those will be possible without 5G Core (5GC). Alongside 5G new radio (NR), 5G Core is a fundamental cornerstone of 5G networks. 

The core is the heart of the mobile network where ultra-connectivity translates into service differentiation and business flexibility. It establishes reliable and secure connectivity to the network and access to its services, determines the quality of service and enforces it through policy allowing services differentiation and handles wide area mobility throughout the network. It is the ‘business end’ of mobile broadband and IoT networks. 

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.

Read our blog post ‘Why do you need a 5G Core network and 5G NR Standalone?

5G Core​ non-standalone or standalone?

It’s not either or. Both are part of a journey towards the network of the future. 

Currently, the vast majority of commercial 5G deployments are based on NR non-standalone (NSA) technology which uses existing LTE radio access for signaling between devices and the network, and Evolved Packet Core (EPC) networks which are enhanced to support 5G NSA. This approach allows new 5G services to be introduced quickly while maximizing the reuse of existing 4G networks. However, to unlock 5G’s full potential NR standalone (SA) and 5G Core (5GC) is needed. 

The new 5GC architecture addresses the needs of not just today, but the future – raising mobile communications to unprecedented levels and making it possible to digitalize entire societies.

In a glimpse, this new architecture called as Service-Based Architecture (SBA), is built using IT network principles and cloud native technology. In this new architecture each Network Function (NF) offers one or more services to other NFs via Application Programming Interfaces (API). Each Network Function (NF) is formed by a combination of small pieces of software code called as microservices. Some microservices can even be re-used for different NFs, making implementation more effective and facilitating independent life-cycle management – which allows upgrades and new functionalities to be deployed with zero impact on running services.

One core with endless possibilities

5G is happening and leading service providers around the globe have already launched commercial 5G services or are about to do so. However, these new 5G networks will co-exist side by side with 4G ones for many years, while at the same time efficiencies need to be improved in order to capture new business opportunities.

With service providers needs in mind, we have developed the Ericsson’s dual-mode 5G Core which combines Evolved Packet Core (EPC) and 5G Core (5GC) network functions into a common cloud native platform that supports 5G NR Stand-Alone (SA) and Non-Standalone (NSA), 4G, 3G and 2G accesses technologies. The solution also includes services exposure capabilities to explore new business opportunities in the industry and in-build software probes to increase 5G network security.

By implementing the dual-mode 5G Core solution service providers will have more control to migrate to 5G on their own pace and in alignment to their business needs.

It enables to:

  • Introduce 5G quickly and effectively while protecting existing services
  • Address new segments with flexibility and agility
  • Reduce cost and increase performance with automation cloud native design
  • Quickly introduce new functionality and do maintenance updates

The network evolution from EPC to 5G core plays a central role in creating a powerful network platform, capable of being exposed and automated, for service providers to extract more value and become contributors in existing and emerging ecosystems.

However, the journey to a full 5G Core is not simple and will imply a technology shift with the adoption of the new 3GPP defined service-based architecture and network functions built on cloud native technology.

The Ericsson’s dual-mode 5G Core is an evolution of our powerful virtualized portfolio, designed for cloud deployment, consisting of our Cloud Packet Core, Cloud UDM and Policy and Signaling Controller products. It can help service providers get the most out of cloud native, microservices, user plane performance and more, enabling new ways of achieving challenging business and operational goals, while migrating to a 5G Core.

Watch to the interview with Folke Anger, Head of Solution Line Packet Core at Ericsson, there he explains what service providers need to have in place to introduce new 5G Core architecture for NR standalone and key learnings from early 5G Core deployments.

Manage TCO with efficiency during your migration to 5G

Total cost of ownership (TCO) is always a hot topic. However, during technology shifts and business transformations it becomes crucial. 

5G Core enables new ways of achieving challenging business and operational goals. Our solution helps you:

  • Manage traffic growth with CAPEX efficiency
  • Reduce OPEX and operational inefficiencies
  • Grow revenue with agility and speed
  • Deployment flexibility and a smooth evolution to 5G
  • Manage TCO during the migration to 5G

New business opportunities with network exposure

The network evolution from EPC to 5G Core plays a central role in creating a powerful programmable network platform for 5G, capable of being exposed and automated, for service providers to extract more value and become contributors in existing and emerging ecosystems. 

With the network exposure capabilities from the dual-mode 5G Core, service providers can now begin to use a common suite of pre-integrated, standard Application Programming Interfaces (APIs) to program and control connectivity services between IoT devices and application functions. This can be done by simply setting API parameters as opposed to running complex network integration projects, allowing for multiple network operations towards IoT devices previously considered impossible or too expensive.

Thanks to our dual-mode core solution - and its embedded API management module - both 4G and 5G core network APIs can be combined into customized service APIs to be exposed to partners and application functions in a controlled and secure way.

Programmability in 5G Core networks has the potential to disrupt today's mobile network business models allowing service providers to expand then offerings to industry 4.0 beyond connectivity.​
