Cloud-native Core

Entering a new era
with 5G core

Enhancing performance for better and stronger Core network

With the continued worldwide commercialization of 5G, users are enjoying enhanced performance that prior technologies could not provide. As new devices and services enter the market, faster speeds and ultra-low latency is required which is only capable with 5G advancements. This shift is also creating a new paradigm for the 5G core network. 5G standalone combined with the core is tapping into new and evolved technologies like cloud-native architecture. Samsung’s cloud-native 5G core is made up of containers, and by adopting a micro-service architecture, each service can be operated independently while also expediting updates and allowing the network to scale faster than before. In addition, operational efficiency is greatly enhanced by dynamically allocating each service as needed through a service-based architecture (SBA).

Riding the new wave of change

Riding the new
wave of change

A new major trend in 5G is building a 5G core on a hyperscalers’ solution. This enables a completely cloud-native network architecture to maximize performance, efficiency and flexibility of the 5G network. In addition, a 5G core through the public cloud reduces operating costs and provides agility as it can respond immediately to service changes.

Flexible resource allocation

Through hyperscalers, operators are able to take advantage of automation and flexible resource allocation benefits. By utilizing AI-based automation technologies of the hyperscalers, which are designed to smoothly predict and process traffic surges, operators can predict the optimal time for core infrastructure expansion and automatically scale-out their core solution onto the public cloud to provide stable and smooth communication services.

Roaming edge service

Another benefit that the 5G public cloud core offers is the deployment of virtualized roaming gateways. By installing core functions at data centers around the world, traffic from subscribers who are abroad can be routed directly to the nearest data center instead of having to pass through the local operator’s core to greatly improve the speed, latency and reliability of mobile services.

Evolving to
5G standalone
at your own pace

Although 5G is growing rapidly, coexistence with existing network technologies is expected to continue for some time. Samsung's core solution supports multi-generation technologies as a single, common core, enabling rapid construction of the latest 5G Standalone core network and smooth upgrade from legacy technologies. It allows operators to naturally transform their core network into a cloud-native based system. The common core also contributes to significantly increased operational efficiency as only one integrated system needs to be managed compared to building, operating, and managing multiple core systems separately. Operators who intend to migrate their network to 5G Standalone run different networks under various environments and conditions. For example, whether a cloud-native infrastructure has already been introduced and which technologies are currently under operation differ from operator to operator. Samsung’s common core solution is ready for any scenario and supports operators evolving to the next chapter of 5G at their own unique pace.

Automating network management from beginning to end

to end

Samsung’s cloud-native core solution lays the foundation for automating many parts of network operation that were previously manually performed, thereby reducing the complexity of network operation and enabling cost-effective operation.

01. Continuous Integration/
Continuous Deployment (CI/CD)

  • Samsung’s cloud-native core enables Continuous Integration/Continuous Deployment (CI/CD), which automates the entire Life Cycle Management (LCM) of network functions. This shortens the time-to-market for software delivery and ensures the system is running on the latest software release version.

02. AI/ML based automation
  • Another important aspect of automating core operation is AI/ML based closed-loop automation. 3GPP is standardizing a new network function, NWDAF, which streamlines how core network data is produced and consumed. Collecting and analyzing data, it generates insights and takes proper action to maintain the best condition of core network operation. This will eventually enable zero-touch automation, excluding human intervention in the operational process and optimize the network to deliver a superior network experience.
