The 5G Core Stack platform is designed by HPE as a pre-integrated software and hardware solution in an as-a-service model. This means that network operators only have to pay for what they actually use. In other words, they will have to invest less in setting up the 5G core network and will be able to tap into new sources of revenue with 5G more quickly.

Some network operators have already started to provide 5G access networks (radio access networks). However, the full benefits of 5G will only be realized when these are combined with 5G core networks. This enables holistic management, shared data usage and so-called "slicing", i.e. the division into virtual 5G networks for specific purposes. However, it is still largely unclear exactly what the performance profiles for the individual use cases need to be. By providing the 5G core stack via the Greenlake as-a-Service portfolio, the scope of the core network can be adapted according to requirements, according to HPE.

"Investing in a new 5G network before revenue returns is a financial challengefor many network operators," said Phil Mottram, Vice President and General Manager of HPE's Communications and Media Solutions business. "With the 5G Core Stack, they can start deployment today and pay for the infrastructure as their revenues grow."

Independent of network suppliers

With the expandable 5G core network, companies can also avoid dependence on network equipment suppliers. Traditionally, the telco industry has relied on proprietary, vertically integrated systems. With the HPE 5G Core Stack, however, network functions can be exchanged as required.

"Openness is essential to the evolutionary nature of 5G," says Mottram. "In the future, services will be delivered over 3G, 4G, 5G, Wi-Fi and edge networks. Service providers therefore need to reduce their operating costs and be open to multiple technologies without being locked into one network supplier."

The 5G Core Stack is expected to be available globally in the second half of 2020 as an as-a-service offering via HPE GreenLake. It is a fully featured, turnkey solution for the 5G core network, built from the ground up as a cloud-native solution and includes containerized network functions (CNF) from HPE and partners, a shared data environment (SDE), a common platform as a service (PaaS) architecture, end-to-end management and orchestration (MANO) and an automation framework.

HPE has also announced the new Aruba Air Pass service, which enables a seamless transition between mobile and Wi-Fi networks. In combination with Aruba Air Slice technology, network operators can extend their 5G reach to Wi-Fi users and IoT devices in the enterprise.
