Hi Sukchan,

In the commercial EPC, the "ignore APN" option is global, then I can set 
a default APN per UE. I have another option to restrict each UE to a 
certain list of APNs. This way, I can have multiple APNs configured, but 
set each UE to its right APN, whatever is configured in the UE.
In my case, the "ignore APN" can be global, but maybe others can be 
interested to do it on a per-UE basis.

Thanks,

Mathieu

>>> I might be wrong here, but I don’t think there is a way allowed in the standards to ignore the UE’s APN. That’s why you can end up even in commercial networks without mobile data access - not knowing the correct APN will make it impossible for the network to route your traffic. Most networks when you connect using an incorrect APN tend to send a text message containing the correct one to fix the issue in the UE.
