Dear Harald,

thank you for explanation, I really appreciate it.

So, osmo-hlr now need authentication for connect to the network? so we cannot attach IMSI without the ki?

if Im not wrong I need to set disable it on the configuration?
 location updating reject cause 13
 encryption a5 1
 authentication optional

on this authentication line need to change? I try do change to authentication disable, but not work. I believe I have wrong understanding here.

Im using for 2g network. as far I know only for 3g network you need ki right?

Hope some feedback. Thank you.

regards,

DUO

the error is quite clear: You have only an IMSI in your HLR, but no authentication
tokens (key material) for cryptographic authentication.

If at the same time you have configured your network to perform authentication (i.e.
not explicitly disabled it), then this will of course result in an error.

Either you enter key data in the HLR for your SIM cards, or you disable authentication.

The BSC has nothing to do with it.  Your error is in OsmoMSC or OsmoHLR configuration.
