SVI-IWF DIAMETER INTERWORKING FUNCTION

Enabling Roaming Between 5G, 4G and 3G Networks

The SVI-IWF Interworking Function enables operators to interconnect between HTTP/2 based 5G networks, Diameter based 4G LTE and SS7 based 2G/3G networks.

Diameter Interworking Function IWF

The SVI-IWF Interworking Function provides networks with comprehensive forward and backward compatibility.

As signalling data traverses an ever-increasing mix of hybrid networks and segments the IWF provides highly flexible protocol support for legacy 3G CAMEL, 4G / LTE Diameter, 5G Nchf / HTTP2 protocols and more.

3G – 4G Roaming

The Interworking Function enables mobile operators’ 4G DIAMETER networks to seamlessly inter-op with legacy networks enabling 3G <—> 4G Roaming capabilities.

4G – 5G Roaming

Providing seamless integration to legacy networks the SVI-DSC’s Interworking Function (IWF) provides a flexible carrier-grade solution supporting 4G LTE to 5G interworking.

WiFi Offload

The SVI Interworking Function enables 4G WiFi or Mobile Data Offloading which allows for further relief of congested networks by way of utilising capacity from unlicensed WiFi spectrum.

Legacy Interconnect

The SVI-IWF ensures that mobile operators can integrate existing legacy infrastructure with new DIAMETER-based components like Online Charging Systems (OCS), allowing them to maximise value in their legacy networks.

The SVI Interworking Function can be deployed as a standalone item or as part of Squire Technologies Diameter Signalling Controller the SVI-DSC.
