gnbsim is a 5G SA gNB/UE simulator for testing 5GC system. The project is aimed to understand 5GC system more efficiently than just reading 3GPP standard documents.
- golang environment on localhost.
- 'Registration Request' doesn't complete for now.
- I will try to update my code step by step...
- running free5gc somewhere.
- subscriber has been registered by free5gc web console.
- change 'ngapIPList' to external ip address in 'amfcfg.conf'
- Downlod the related files.
$ git clone https://github.com/hhorai/gnbsim.git- Build example binary.
$ cd gnbsim/example
$ go build- Edit the configuration file. In case of free5gc with default configuration, it might not be needed to edit, excluding 'msin' parameter.
$ vi example.json- run 'example' with 'ip' option and specify the AMF ip address.
$ ./example -ip <AMF NGAP listen ip address set above>- Then you can find the following line in the debug message. In this case, your configuration for free5gc and gnbsim are both correct.
