Hello authors,
+1 on the problem statement. I think a uniform approach to mapping system
framework is very much needed.
But  if it is ID specific there are many more functionalities related to
Identity in the networks than just the mapping systems. Is the scope only
limited to mapping function aspects?

I also have some questions in the mobility section.
- In 7.1.1, "we  assume that ID functionality is handled within the network
and is transparent to the UEs or hosts."
What kind of ID functionality is being assumed here?
- Figure in 7.1.1 assumes that MGW is only required for mobile networks.
Are you saying that Host1 and Host2 are not ID enabled and IDs are only
mappable in mobile networks. So, if UE does not need mobility, it need not
go through MGW?
- Can I assume that functional block "Mapping System" is missing from
figure? OR is it not same as the MGW?

1.  The new carrier provides the full locator (mapping to
       Base_station2) and the MGW sends directly to that locator

- Not sure what you said in this part and the lines that followed in 7.1.2.
Could you explain what is full locator (vs just locator) and only
significant in inter-provider case? a UE can move from one base station to
other in single provider network too. Why wont you need 'full locator'
there?

Thanks
Kiran
