Title : Using DHCPv6 for Prefix Delegation in IEEE 802.16 Networks

In the 802.16 Per-MS interface prefix model, one prefix can only be
assigned to one interface of a mobile station by an access router and
different mobile stations can't share a prefix. Managing Per-MS
interface prefixes is likely to increase the processing load at the
access router. Based on the idea that DHCPv6 servers can manage
prefixes as well as addresses, we propose a new technique in which
the access router offloads delegation and release tasks of the
prefixes to an DHCPv6 server. The access router first requests a
prefix for an incoming mobile station to the DHCPv6 server. The
access router next advertises the prefix information to the mobile
station with a Router Advertisement message. When the mobile station
hands off, the prefix is returned to the DHCPv6 server. We also
describe how AAA servers can help in prefix delegation.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
