Liang - Most important point is to get a location
information as accurate as possible. Even IS
Server can support POA location Information,
user can't judge the current
location without redundant services as GPS...I
am not sure how many user will bring GPS interface
on its mobile terminal.

heterogeneous HO
Hi Daniel,
I think there will be an improvement to the power management. For
example, different network interface has different energy consumption in data
transmission. Network A may cost less energy per byte but the bandwidth
is narrow. Network B has the board bandwidth but the power management is
inefficiency. Thus, when an 802.21 client enters into the intersection
area of Network A and Network B, the client may prefer network A for the
background download service, and prefer Network B for the video service.
Thanks!

HO
Hi all,
I am also interested to the topic of power management in heterogeneous
networks. I suppose there is an optimal trade-off among power
consumption, network delay and throughput, due to the selection of
network. Would anyone here show me your works/considerations on the
topic?
Thanks!
Sincerely yours,

Hi
all, just need to raise the interest of this issue on the mailing
list.
While looking at the 05 draft, one issue occurs in my mind.
As shown in the Subject line, I think we should consider how the
mobile station with multiple wireless interfaces can consume its power
consumption as efficient as possible. Very simple scenario is to enable
all wireless interfaces regardless of link connection. Whenever
detecting a new wireless link, the selected interface can be an
alternative interface of vertical handover. However it is toooo much
expensive and unexpected scenario to be adopted on the real networks
and even commercial model. To me, still existing document does not
take care of that deeply, so I'd need to make our efforts on this
issue...One suggestion is to take a wide-coverage tip for notifying the
overapped region such as GPS and even Cellular Positioning Service. I
am not sure these are in-scope of 802.21 though...
Any idea
?
