2 years ago In order to test 5G SA all you need to do is the following
docker-compose -f sa-deploy.yaml up
brings up only the 5G components of 5GC
For the gNB
docker-compose -f srsgnb.yaml up -d && docker attach srsgnb
the differentiating factor between eNB and gNB in srsRAN is the cells configuration in rr.conf. Refer rr_gnb.conf and rr.conf files under srslte folder in this repo.
please comment out the following in your enb.conf
dl_earfcn = 6300
tm = 4
nof_ports = 2

Problem
Hello. I want to launch a 5G network. But I get an error all the time.
Failed to initiate S1 connection. Attempting reconnection in 10 secondsI read a lot of documentation, I understand and assume that there is an error in the config. But I have already tried to specify different ip addresses (mme, amf).
Logs
I can provide the log of the following containers:

I run srsENB like this.
docker-compose -f srsgnb.yaml up -d && docker attach srsgnbenb.conf
