(UANGEL-Integrated Signaling Controller)
As LTE becomes popular and the amount of data use increases explosively, Diameter traffic also increases quickly, which is a required protocol for authentication and charging. In addition, networks become more complex, as demand on the interface between existing networks and new networks increases for policy management, authentication, and charging. The UA-ISC system provides more efficient traffic management environment by offering various routing functions and protocol conversion setting functions in a GUI environment, while supporting the Diameter routing function (DRA/DEA/IWF) as defined by the 3GPP/GSMA by default.
|DRA (Diameter Routing Agent)||A system that routes the Diameter message inside the network.|
|DEA (Diameter Edge Agent)||A system that relays Diameter messages between internal network and other networks during roaming.|
|IWF (InterWorking Function)||A system that supports the Diameter message interface function between existing networks and new networks.|
