On behalf of Bart (https://www.facebook.com/groups/LTE.Professionals )

The 24.301 talks about in in details.

If I recall correctly.. If the APN UE is requesting is in the subscriber's profile but it's not set as default then everything is fine and UE will attach.

Because in HSS profile more than 1APN can be set.

If the APN is not in the list then I don't think session will be established.

For example it can be used in the HSS mnc.ncc.3gppnetwork.org and in the MME mnc.ncc.3gpp.org. Or must be same mnc.ncc.3gppnetwork.org?

It's just a general question, popped up when i was reading a document. For instance Suppose an APN configuration of an message say Update Location Request (ULR) is not present in HSS and MME has sent the message which has reached there in HSS. What will be the reaction of HSS?

eg: if apn is abc.ap1, length of apn IE of create session request should be 7 or 8.?
If it is 8, what will be data type ?
I got little confused after reading specs (3gpp 29.274 clause 8.6 & 23.003 cl. 9.1, RFC 1035 3.3), the APN IE is encoded as one or more labels.
