SVI-IWF INTERWORKING FUNCTION

Enhance multi-generation 5G, 4G, 3G Network Functions

The SVI-IWF HTTP-2 Interworking Function enables HTTP/2, Diameter, LTE and SS7 network interconnections to implement new revenue streams and extend network functionality and lifespan.

HTTP-2 Interworking Function IWF

Mobile core networks are becoming more complex as operators seek to deploy 5G. Operators are faced with difficult trade-offs, weighing the replacement of existing network components against the revenue potential of 5G.

The 5G SVI-IWF Interworking Function provides networks with comprehensive forward and backward compatibility. Operators can reduce 5G deployment costs by extending the life of existing infrastructure.

The agile 5G-IWF supports 5G HTTP/2, legacy 4G LTE Diameter, and 3G MAP/CAMEL protocols, and more, as network slicing, private networks, MIMO, and other 5G functions create ever more diverse networks for signalling data to traverse.

Commercial Off The Shelf

Supplied on standard Dell servers.

Virtual or Cloud Deployment

Virtual Machine deployed on industry-standard servers in a data centre environment using a hypervisor, i.e. VMware, or Virtual Network Function (VNF) in AWS, Azure, OpenStack, Nokia, Oracle Cloud and Google Cloud infrastructure.

Enhanced Network Functions

Network functions are faster with network function virtualisation architectures and containerisation.

4G – 5G Roaming

The Interworking Function enables mobile operators’ 5G HTTP/2 networks to seamlessly inter-op with legacy networks enabling 4G <—> 5G Roaming capabilities.

WiFi Offload

Use unlicensed WiFi spectrum capacity for network decongestion using the 5G SVI-IWF for 4G and 5G WiFi or Mobile Data Offloading.

Hybrid and Multi-Environment Deployments

Fully on-premises, fully cloud or combination network function deployments are possible with Physical-, Containerised- or Virtualised Network Functions (PNF, CNF, VNF).

The 5G SVI-IWF is part of Squire Technologies’ 5G Signalling Controller, the 5G SVI-HSC, but can also be deployed as a standalone item.

Legacy Interconnect

Extract additional value from legacy network components, using the 5G SVI-IWF to integrate mobile operators’ existing network infrastructures with HTTP/2-based components like 5G Charging Functions (CHF).

Interworking and Extended Support

The flexibility of the 5G SVI-IWF helps operators to stay competitive. Use it to extend and enhance operational and business layer services by integrating leading-edge CHF components in next-generation or legacy networks.
