5G isn't simply an evolutionary change – a new ‘G’ or a new radio interface. The core network has been rearchitected in the 3GPP specifications to be more open, dynamic and intelligent through the use of cloud native concepts and a DevOps approach. In the cloud native model, the network functions that make up the core are stateless, storing data in a centralized data environment. This allows operators to update or change the network functions faster without impact to service.
5G also introduces the concept of network slicing, allowing operators to create virtual 5G networks for different services with vastly different characteristics. For example, a highly reliable low latency service for autonomous driving, or a low bit rate and long-range service for smart meters.
Rather than evolving from an existing code-base, HPE took the decision to design its solution from the ground up to be cloud native and open, allowing telcos to use NFs from different vendors. In order to balance the complexity, it is introducing a complete 5G core stack with pre-integration of NFs from itself and its partners, all on HPE's carrier-grade infrastructure.
