UE and eRAN verification with NG40-EPC
UE and eRAN test topology
NG40-EPC

The NG40-EPC test system provides fully 3GPP compliant S1 and S1-U interfaces. NG40-EPC works with eNBs (LTE Macro cells) and Home eNB's (LTE Femto cells). A build-in Home eNB Gateway for Home eNB aggregation and traffic tunneling is supported as well. Thus, user can choose between internal and external Home eNB Gateway or to omit it completely.

NG40-EPC has been designed for the following areas:

  • Functional Tests: eNB / UE protocol stack and message flow conformance
  • Load and Capacity: eRAN performance analysis and benchmarking
  • Packet Core Emulation: Practical demonstration of eNB's and UE's in show-rooms, during products trainings and exhibitions
  • Light-weight Network: Application development, IT-Security, Deep-packet inspection
value chain

NG40 is more than a 4G simulator:

Versatile testing tool due to the concurrent support of GPRS, UMTS and LTE procedures: Not only 4G Handovers, like Intra- and Inter-eNB handover, but also Fallback Scenarios can be verified. NG40 emulates up to 500 EPC with unique PLMN-ID; precondition for complex Roaming Tests.

IT-Security: Traffic generation including message distortion makes it possible to stimulate abnormal conditions like the presence of fraudulent subscribers or manipulated network nodes. NG40 supports virtually all cipher and integrity protection mechanisms as specified in 3GPP 33.401.

Application Development: With S1/Gi-Bridging any application server can be connected to the test system. This allows to verify what impact mobile conditions to the user application have.
