Multi-Access Edge Compute

Fusion Core is a cloud native implementation of the 3GPP standards-defined 5G Next Generation Core (5G NGC or 5GC) that allows 5G network operators to aggregate data traffic from all end devices over multiple wireless and fixed access technologies.

Network slicing

Fusion Core deployments can be configured to provide multiple network slices to multiplex independent logical networks. All network functions within a single Fusion Core deployment serve all of the configured slices.

UE MTU configuration

usion Core’s SMF signals the MTU for a Data Network to UEs on request as part of PDU Session Establishment procedures to avoid fragmentation.

Policy control

Fusion Core applies end to end policy control decisions and enforcement on a per PDU session and per flow basis. This provides the flexibility you need to apply different QoS levels to particular flows or UEs, and allowing you to selectively expose services or data networks to groups of UEs and controlling the types of traffic flowing over the network.

UPF Access Control Lists (ACLs)

ACLs can be used to either allow or block traffic addressed from or to specific IPv4 address ranges. You can configure ACLs in Fusion Core’s access (N3) and core (N6) interfaces.

5G Network Functions

Deployment in private networks

Fusion Core uses the capabilities of the Azure private multi-access edge compute to provide a 5G solution for enterprises that combines the performance and low latency from Edge compute resources required to support Industry 4.0 use cases, with consistent, centralized management through Azure.

Edge deployed

Deploying Fusion Core at the enterprise edge ensures that it is as close as possible to the devices it serves, allowing it to deliver low latency levels and reduced backhaul through local data processing when combined with application logic in the same location. This provides a number of valuable benefits to enterprises, including the following.

UE Security Context Management

Fusion Core’s AMF performs ciphering and integrity protection of 5G NAS. During UE registration, the UE includes its security capabilities for 5G NAS with 128-bit keys.

The algorithms supported by Fusion Core for ciphering and integrity protection include the following.

  • 5GS null encryption algorithm
  • 128-bit Snow3G
  • 128-bit AES
  • 128-bit ZUC

Pure 5G and 4G Interworking support

Fusion Core can be deployed in purely 5G scenarios. In this case, Fusion Core runs in 5G Standalone mode.

Fusion Core also supports 4G Interworking, providing service to 4G UEs over a cloud-native core. This is known as 4G mode. For greenfield and incumbent network operators, 4G mode provides an immediate path to 5G without continuing investments in maintaining a 4G core.

Fusion Core is delivered on a Virtual Machine (VM) known as the Fusion Core Base VM. The Fusion Core Base VM is designed to be deployed as an Azure-managed application on an Azure Stack Edge (ASE). The Network Functions and infrastructure components required to deliver Fusion Core function are deployed as containers on the Fusion Core Base VM and orchestrated by Kubernetes.
