UA-ISC

UA-ISC

(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.

System
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.
Key features
  • Complying with the 3GPP/GSMA/ETSI/IETF standard.
  • Supporting the HSS, PCRF address resolution function.
  • Providing multi protocol (Diameter, SIGTRAN, Radius, HTTP, etc) routing and protocol conversion function.
  • Providing policy-based routing and load balancing function.
  • Providing the policy-based overload control function.
  • Providing the easy message conversion function based on the DQLTM(Diameter Query Language).
  • Providing a convenient operating environment using the GUI-based routing policy management function.
  • Providing the service/session control function by mounting SLEE.
  • Ensuring strong network interface compatibility by adopting the internally-developed protocol stack.
Major references
  • Established the integrated Diameter network in a WCDMA/LTE/EPC mixed environment.
  • Created an interface environment with non-Diameter network nodes.
  • Secured stability by forming an alternate routing environment within the area/among areas.
