Fraunhofer FOKUS releases Open5GCore Rel. 4

 In News

During the FUSECO Forum 2018, Fraunhofer FOKUS launched the 3GPP Release 15 based Open5GCore being the first 5G core network implementation that we will use as basis for the 5G-VINNI Patras and Berlin experimental facilities.


The new Open5GCore features a large number of new components which enable the establishment of true 5G testbeds, breaking from the LTE/EPC prototypes:

  • Integration with 5G NR standalone

o   N1 interface [with an implementation of a UE simulation and of the AMF and SMF]

o   N2 interface [NG-AP with a simulated gNB towards the core network]

o   N3 interface – we have ported the GTP modules from the Open5GCore Rel. 3

  • Data path diversity support:

o   N4 interface – a new implementation of PFCP supporting chaining of UPFs, data path selection and data path reselection.

  • A basic implementation of SBA – this includes HTTP/2, OpenAPI and REST as well as an exemplary NRF and very basic AUSF/UDM
