Connect more than one sdr #865

Closed faratell closed 1 month ago

faratell commented 1 month ago

Hello. Is it possible to connect two (or more) SDRs to srsRAN_4G (or srsRAN_project)?

pgawlowicz commented 1 month ago

With srsRAN_project, it is possible to run disaggregated gnb with multiple DUs each connected to own SDR.

Thanks. I do not have access to 5G SIM cards and handsets. I use oyeitime 4G& volte simes and usrp b210. Can 4G SIM cards and open5gs (4G or 5G) core integrated with srsRAN_Project?

pgawlowicz commented 1 month ago

It should be possible, please try and report back.

faratell commented 1 month ago

I tested my 4G SIMs in the srsRAN project with 5GC, but the SIMs cannot find the network. Additionally, the gNB cannot directly connect to the EPC Open5GS core. Should I follow the NSA architecture with eNB + gNB and the EPC Open5GS core?

please follow this tutorial https://docs.srsran.com/projects/project/en/latest/tutorials/source/cotsUE/source/index.html

Perhaps the problem is that my phone does not support 5G.

Hello. I use a phone that support 5g. My sim is Oyeitimes 4G simcard. I run this function in open5gs: nrf,scp,amf,smf,upf,ausf,udm,pcf,nssf,udr and bsf .

My sim can find open5gs 5G network but can not register on it. in amf show this error: [gmm] INFO: [suci-0-001-01-0-0-0-0000000018] SUCI (../src/amf/gmm-handler.c:157) 11/09 11:09:56.796: [gmm] ERROR: [suci-0-001-01-0-0-0-0000000018] HTTP response error [400] (../src/amf/gmm-sm.c:1555) 11/09 11:09:56.796: [amf] WARNING: [suci-0-001-01-0-0-0-0000000018] Registration reject [95] (../src/amf/nas-path.c:219) 11/09 11:09:56.933: [amf] INFO: UE Context Release [Action:3] (../src/amf/ngap-handler.c:1677) 11/09 11:09:56.933: [amf] INFO: RAN_UE_NGAP_ID[0] AMF_UE_NGAP_ID[1] (../src/amf/ngap-handler.c:1678) 11/09 11:09:56.933: [amf] INFO: SUCI[suci-0-001-01-0-0-0-0000000018] (../src/amf/ngap-handler.c:1681) 11/09 11:09:56.933: [amf] INFO: [Removed] Number of gNB-UEs is now 0 (../src/amf/context.c:2530) 11/09 11:09:56.933: [amf] INFO: [Removed] Number of AMF-UEs is now 0 (../src/amf/context.c:1663)

and in nrf show this error: 11/09 11:09:31.686: [nrf] INFO: [c2196076-9e6d-41ef-aa3b-db7872dff51e] NF registered [Heartbeat:10s] (../src/nrf/nf-sm.c:190) 11/09 11:09:56.796: [nrf] ERROR: Invalid API name [nausf-auth] (../src/nrf/nrf-sm.c:243).

Did you add the UE data to the subscriber database?

could you share ngap.pcap file?
