Re: [STDS-802-11-TGBH] Duplicate IRM



Hi, Jay,

 

Actually, I think you have identified an error in REVme, and thanks for that!  The case in bullet (c) is (at least in my opinion), _not_ mobility within a network.  I’ll suggest that TGme look at this, and clarify the intention.

Hi Graham,

 

Thanks for set-up the mail thread.

 

There is no clear definition about the term of "network" in 802.11 draft, but it's also widely used in many place. If we read the following citied paragraph, it indicates a network may contain multiple ESSs , while our original agreement is that the 11bh identifier can be recognized by any AP in the same ESS . And thus I think we can't use "network" if we don't plan to use the 11bh identifier across different ESSs .

 

 

4.5.3.2 Mobility types

The three transition types of significance to this standard that describe the mobility of (M12)non-GLK STAs within a network are as follows:

a) No-transition: In this type, two subclasses that are usually indistinguishable are identified:

1) Static—no motion.

2) Local movement—movement within the PHY range of the communicating STAs , i.e.,

movement within a basic service area (BSA).

b) BSS -transition: This type is defined as a STA movement from one BSS in one ESS to another BSS

within the same ESS . A fast BSS transition is a BSS transition that establishes the state necessary for

data connectivity before the reassociation rather than after the reassociation .

c) ESS -transition: This type is defined as STA movement from a BSS in one ESS to a BSS in a

different ESS . This case is supported only in the sense that the STA might move. Maintenance of

Subject: [STDS-802-11-TGBH] Duplicate IRM

Following today’s meeting I have amended and uploaded 23/1392r4 with the changes discussed, adding robust action frames and PASN Class 1a.

Please see the updated version here:

https://mentor.ieee.org/802.11/dcn/23/11-23-1392-04-00bh-cid-7-21-114-resolutions-for-duplicate-irm.docx

 

Hopefully the remaining work is only to decide on an alternative term for “network” in the sentence.

“If the new IRM is already in use within the network, or identical to a most recently received IRM for another non-AP STA, then, after association or authentication using PASN , the AP may send an IRM Duplicate Action frame (see 9.6.aa.2) to the non-AP STA indicating to the STA that the provided IRM is a duplicate.

 

Comments and suggestions please.

 

To kick it off, how about “WLAN ”?    (term defined in clause 4.2?)

 

Graham
