Simulate 4G/5G base stations and terminals based on open source software platforms

1. Program background

Using THE USRP and SRSRAN, OpenAirInterface5g open source software platform, you can realize the construction of 4G/5G analog base stations and terminals, and realize the following functions: deploy a dedicated network; for teaching and scientific research, research base stations, terminal operation structures and protocols Develop test products, such as some test features that replace the CMW500.

Solution Introduction:

srsRAN

srsRAN is a 4G/5G open source software-defined radio suite. SrsRAN supports UE and eNodeB/gNodeB applications and can be used with third-party core network solutions to build a complete end-to-end mobile wireless network

OpenAirInterface(OAI)

OpenAirInterface5g is an open source SDR LTE project initiated and maintained by the European EURECOM organization, which has been implemented as an excellent open source software according to the 3GPP protocol LTE/NR full end-to-end functionality

According to the standard of 3GPP, OAI fully implements the core network, base station and user three parts of the LTE/NR protocol.

The LTR/NR network architecture is as follows:
