Hi All,

Does anyone tried enabling the A5/1 Encryption using osmo-bsc and osmo-msc?

We are using an UPBOARD with the following elements; osmo-bsc, osmo-bts-trx and 
osmo-trx in it; and a NUC with osmo-hlr, osmo-msc, osmo-mgcp, and osmo-stp.

Both servers are using Ubuntu 16.04 OS.

We enabled the a5/1 encryption in both osmo-bsc and osmo-msc. Then provisioned 
the programmable SIM to osmo-hlr with aud2g comp128v1 auth.

OsmoHLR# subscriber imsi 515941234567890 show
    ID: 9
    IMSI: 515941234567890
    MSISDN: 09271234567
    2G auth: COMP128v1
             KI=00112233445566778899aabbccddeeff

We are not really sure what causes the LOCUP Reject.

Can anyone help us with this issue?

Attached are the configuration used during the testing and a trace taken during 
the testing.

Best Regard,

Ron Menez
