Hello, Peretz. I hope your new year is happy and
prosperous. I apologize for being cryptic, especially since I wasn’t
making a deep or a constructive point. To be clear now, my assumption is that
even a single radio mobile node will need to choose between multiple handoff candidates
based on some “link quality”. I don’t know what the SG will
determine a good measure of link quality is, or even how many dimensions it will
have, but I would expect there to be one. I make no claim about the handoff utility of 802.11k. All I
meant to point out was that the stated design philosophy of 802.11k was to use information
that “was already there” but not uniformly accessible. As work in
the SG progresses, they may need link information that is not in the current LINK
SAP. By that philosophy, a mechanism that satisfied those needs but required,
say, new timers in an existing protocol would be a “bad idea”, no
matter how valuable it might be to an application. Adding new accessors would presumably
be OK. --Dennis From: Feder, Peretz
(Peretz) [mailto:pfeder@xxxxxxxxxxxxxxxxxx] Hello Dennis: Sorry but I am afraid I lost w.r.t your line of thinking. Are you saying 802.11k is a good model for a single-radio HO? What are the single radio aspects of 802.11k? Appreciate some more background pls, Happy new year, Peretz Feder From: Dennis Edwards
[mailto:dedwards@xxxxxxxxxxxx] Junghoon, Congratulations on your chair appointment. I wish you the
best of luck in your new endeavor. Just a thought, and I apologize if I am out of touch, but should
link quality information be needed, perhaps the 802.11k model would prove
useful. Recognizing the enduring achievements of Mr. Paine, it may be more
palatable to the EC than other approaches have been. Best regards, --Dennis From: Gupta, Vivek G
