[srslte-users] is there any document about how to config srsepc with COTS UE

[john wu]

Hi Pedro,
thanks for your reply. i did not see you have replied me.
i have another question.
I use srsenb run with oai epc it run well. but after i switch to srsepc it shows MAC code failure in the log and authentication is failure.
my user_db configure is like this
ue3,mil,(imsi),(ki),opc,(opc code),8000,000000001255,7,dynamic
imsi and ki and opc code is read from sim card reader.

Hi John,

No specific document, but it's pretty straight forward.
To configure the EPC, you will need to know the following parameters
of the SIM card: IMSI, K, OPc and authentication algorithm.

The IMSI is the unique identifier of the SIM card, the K the secret
key that the EPC and the UE use to authenticate each other, and the
OPc is an operator code (ciphered with K).
The usual authentication algorithm is MILENAGE, but there are some
test SIMs that use XOR as the authentication algorithm.

There is a CSV file where the these are configured in srsEPC, the
user_db.csv. Checkout the user_db.csv.example and change the
parameters accordingly so that they match the ones on your SIM card.

Also, make sure to change the MMC and the MNC in the EPC and the eNB
so that it matches your SIM's PLMN. These parameters can be changed in
the enb.conf and the epc.conf.

If you are still having issues you can run the eNB and the EPC with an
option to collect pcaps, by doing "sudo srsenb --pcap.enable=true" or
"sudo srsepc --pcap.enable=true"
You can examine these to troubleshoot your issues and if you still
don't understand what is wrong you can send your questions to the
mailing list.

Hope this helps,
Pedro
