Robert,

Here is a relevant sentence in the MIPSHOP charter:

===================
Additionally, the IEEE 802.21 Media Independent Handoff (MIH) working
group aims at providing services to assist with handoffs between
heterogeneous link-layer technologies, and across IP subnet
boundaries. The information exchanges defined by IEEE 802.21 are
classified as MI (Media Independent) Event Service (MIES), MI Command
Service (MICS), and MI Information Service (MIIS). The MIIS provides
topological and location-related information of service networks. The
MIES provides timely communications of wireless environment
information via the delivery of events originating across the
link-layer or farther away. The MICS is an analogous service for
commands which can change the state of the wireless link or of a
host's point of attachment, potentially triggering further event
generation. MIH services can be delivered through link-layer specific
solutions and/or through a "layer 3 or above" protocol. MIPSHOP will
define the delivery of information for MIH services for this latter
case. Notice that this allows the network information to reside
anywhere (not necessarily across the link-layer hop), and enables MIH
services even in the absence of the corresponding link-layer
support. An L2 or L3 based mechanism to identify a valid information
server is also required; in particular for L3, we expect that any of
the several current L3 discovery mechanisms will be used. A liaison
with IEEE 802.21 has been established, and access to the IEEE 802.21
drafts is granted to mipshop members. Interested members need to send
a request to the WG chairs in order to obtain a copy of the current
IEEE 802.21 draft.
===================

"MIPSHOP will define the delivery of information for MIH services for
this latter case. Obviously, MIH means IEEE 802.21 not *mobility
service*. No doubt. Anything else ?
