SVI-IWF DIAMETER INTERWORKING FUNCTION

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.

Comprehensive Interconnect

As mobile telecoms continues its evolution towards 5G 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, and 5G Nchf / HTTP2 protocols and more.

  •   

  • Enables roaming between 5G, 4G and 3G networks

  • Relieve network congestion with WiFi offload

  • Enhance and and extend the life of existing networks

  • Full interworking with MAP, CAMEL, RADIUS, DIAMETER, HTTP/2 signalling

  • Full interworking with OSS / BSS over SOAP, XML, SQL, JAIN, JSON, HTTP/2 and Nchf etc

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 insures 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.

Interworking and Extended Support

The SVI-IWF allows operators to integrate new leading edge OSS / BSS components to their next generation or legacy networks. The flexibility of the SVI-IWF insures operators can confidently extend and advance their operational and business layer services to insure they remain completive.
