Fundamental 5G Core Network Functionality

Open5GCore Rel. 6 implements the essential features necessary for the end-to-end 5G system deployment and aligned with 3GPP Release 15 and 16. Open5GCore Rel. 6 includes a set of new components addressing 5G Standalone Core Network which were developed separately from the previous EPC components. Through this, a genuine 5G core network can be used as parts of the testbeds.
