| 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. Daniel (Soohong Daniel Park)

  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!   -Liang

    I think "TYPE_IE_POA_LOCATION" Information 
    Element would be very reasonable in terms of power 
    management on the local stack. Given this informatio, user 
    will judge the right timing which to turn an interface 
    on.

    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,   Liang Chen

    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 
      ?
 
 Thanks,
