About macrocell S1 attach problem about open5gs HOT 8 CLOSED

Please check PLMN_ID in NextEPC configuration file

Your eNodeB is set to MCC(001), MNC(01).
But, your NextEPC PLMN_ID is set to MCC(001), MNC(09).

Thanks!

Oh!!
The configuration file is indeed incorrect.
I'll modify it soon.
Could you tell me how you find the problem?

Thanks a lot!

See the packet capture file with wireshark.

Your eNodeB sends S1SetupRequest with MCC(001), MNC(01).
However, your MME sends S1SetupResponse with MCC(001), MNC(09).

Thanks!

Hi

Could you also tell me what do "mme_gid" and "mme_code" in nextepc.conf mean?
I don't know how to fill the value of my configuration file.

Thanks a lot!

from open5gs.

It is just used for GUMMEI or GUTI.
You can use any value at this point.

Please see LTE identifier link

Thanks!

Hi

I've modified the configuration file nextepc.conf.
But the macrocell seems unable to work normally.
Could you help me find where the problem is?

Here are the files:
s1ap debug level is set to 5
nextepc.conf.zip
nextepc.log
0427_macrocell_failed.pcapng.zip

Some information about macrocell:
eNB id=227
TAC=0x7B=123
CellID=0xE301

Thanks a lot!

There is no log for UE access. I don't know the root cause from your attached files.

You will be able to remove the MCC (001), MNC (09) related parts from nextepc.conf.
However, I have no idea whether this will be resolved or not.

Sorry not to help you!

Hi
I solved the problem by myself.
The reason why macrocell doesn't work normally is setting the wrong value for mme_gid and mme_code.
After givinig the correct value, it works!!
