1 IWF Installation Overview
This sections provides overview information of IWF.
The Oracle Communications 5G InterWorking and Mediation Function (IWF) enables 5G Core NFs to communicate with Evolved Packet Core (EPC) network elements. IWF is a Cloud Native solution based on microservices architecture that is deployed as an independent network function in the 5G network or as an independent microservice within the 5GC NF, as a part of Oracle 5GC NFs like NRF, SEPP, SCP, and so on.
IWF includes the following features:
- Protocol Translation:
- IWF allows 5GC NF to interwork with the EPC network elements or vice versa.
- IWF supports protocol conversion capabilities from Diameter to HTTP/2 and vice versa.
- Message Mediation:
- This feature allows API transformation to resolve inter-NF inter operational issues.
- Allows users to create policy rules to execute mediation transformation.
