Thanx Kalyan for your comments.
Cost:
Yes it needs to be more than a binary
value.
But still it’s never easy to compare
cost of accessing different networks, since it’s not always expressed in
same units for different networks.
Higher Layer Services:
That’s also a good idea. Do we need
get to get more specific here about different services or just let network
providers list these services in the form they want.
Providing this information before
authentication/authorization may help.
But if you are connected to one network,
you could get this information before connecting to other networks thus automatically
avoiding that.
The only other case where you may need
this explicitly before authorization/authentication is when you are not
connected to any network, but you could always start with some default
preferences in such cases.
Best Regards,
-Vivek

Betreff: [802.21] 802.21
Information Elements
When it comes to 802.21 Information Service, we have had
quite a bit of discussion on different encoding schemes, access/query
mechanisms, L2 vs L3, etc. However one aspect where we have had relatively less
of a discussion is the Information Elements themselves.
Please find the attached document which lists the different
IEs currently under consideration in 802.21. The doc makes no attempt to
organize/encode these IEs in any particular way (schema etc.). The intent is to
just focus on INFORMATION itself ...
Please send in your comments and any other suggested IEs
that may help from handover perspective.
We shall compile all received feedback and submit this as
updated/consolidated list of IEs for next meeting.
Best Regards,
-Vivek
