ABSTRACT
In this demo we show the current implementation status of the OpenAirInterface (OAI) 5G non-standalone (NSA) system operating with a common-of-the-shelf (COTS) phone in the sub-6 GHz band. The radio access network (RAN) comprises an OAI eNB and a gNB, both running on general purpose x86 servers and USRP N310 software defined radios. Further we use the OAI evolved packet core (EPC) comprising home subscriber server (HSS), mobility management entity (MME), serving and packet data network gateway (S-PGW), which are all deployed in Docker containers. In the demo we will show the initial connection and user registration on the 4G cell, the secondary cell addition, the initial connection on the 5G cell and some initial traffic on the 5G cell.
