As operators deploy LTE, they have to manage integration and interoperability between multiple network elements of different vendors, across different access technologies. Signalling interworking is becoming a key function to help enable service scenarios faster and more cost efficient.
What The Interworking Function (IWF) does
The Interworking Function (IWF) bridges 2G, 3G, 4G/LTE, Fixed and Wi-Fi network technologies, as well as integration with IT and Billing environments. By means of this Interworking Function, operators can centrally resolve interoperability issues and enable use cases across Network and IT systems from different vendors.
The Interworking Function provides:
- Protocol conversion and mediation
- Service logic
- Support for a wide range of protocols, such as Diameter, RADIUS, HTTP, LDAP and SS7.
Typical use cases for IWF are:
- Diameter interface mediation (dealing with proprietary extensions/variants of the protocol)
- Fixed/Wi-Fi - Mobile convergence (RADIUS – Diameter interworking)
- 3G - LTE interworking (Diameter – MAP/SS7 IWF as defined in 3GPP TS 29.305)
- Network - IT interworking (Diameter – SOAP, XML/HTTP, LDAP …)
- Database access and interaction, Big Data enablement
Infradata's IWF Gateway
Infradata delivers the world’s first productised IWF gateway, providing any-to-any interworking, routing and service orchestration. This carrier-grade, high performance solution is designed for enabling signalling use cases across Network and IT systems from any vendor, without the need for R&D. With better control over complex integration projects, the IWF gateway is the smartest choice to get new services deployed faster and cheaper than any one-off IT project could ever achieve.
We power the most innovative platforms for the telecom ecosystem. Infradata is committed to cloud-native applications and services across our end-to-end portfolio to deliver the networks of the future.
Equipment Identity Register
The Next Generation EIR solution. EIR provides a Next Generation EIR enabling a single, unified access point for Mobile Equipment authentication in the network.
Signaling Transfer Point (STP)
The STP runs on any off-the-shelf hardware or in a virtualized environment. It is a 100% software based solution, supporting virtualization and cloud deployment (VMWare, KVM, OpenStack etc.).
Diameter Signaling Controller (DSC-DRA-DEA-IWF)
Diameter routing, any-to-any interworking, mediation, protocol conversion, load balancing and advanced service logic for a wide range of protocols.
