IETF RFC3344 and MIDP2

[serge masse]

I am researching the relationships, if any, between MIDP2 and RFC3344 specs and I am having difficulties in finding specific info. Can someone please point to a good URL on the subject of *MIDP2-and-RFC3344* (Mobile IP)?
rfc3344 Mobile IP is at http://www.ietf.org/rfc/rfc3344.txt
also, does Michael's book Enterprise J2ME mention it?
thanks,

No, the books sits on top of the protocol layer. Actually, it is even above the API level and focuses on overall application designs using real examples.

I am still searching and I found this page: http://www.computer.org/internet/v2n1/perkins/figa.htm (a Sun employe).
which shows that Mobile IP is at the same networking layer as IP, thus lower than TCP. Therefore, a possible protocole could be TCP/MobileIP instead of TCP/IP.
if no Java API are currently compliant with Mobile IP, then are there any plans to make some Java API to be compliant with TCP/MobileIP?
thanks,

Thanks for the clarification Michael.
Btw, I find the issue of Mobile IP (rfc 3344) important because MIDP 2 now supports TCP/IP sockets on mobile devices, so what is the relationship with the IETF standard on this kind of communication?
Did JSR-118 (MIDP2) just left it to the JRE implementers to decide what to do about RFC3344?
Did they ignore it?
Is JTWI (JSR 185) considering it?
btw, it looks like the US military has been considering RFC 3344.
I found very little info younger than 1 or 2 years old so far.

RFC 3344 is about having mobile devices keeping a permanent address even when they move.
So the question is, what kind of mobile TCP address permanence is offered by current carriers that offer MIDP 2 devices with a JRE that supports TCP server sockets?
I'm starting a new thread on this question because it needs a better label.
