RE: [802.21] 802.21: Scope

Hi Peretz/Phillip/Michael/All,   

 

Thanks for clarification. Let me summarize. I see following pieces of the puzzle:

 

a.    802.21 would define abstract triggers and send request for media specific changes to 802.16g.

b.   802.16g would make appropriate MAC / PHY changes required to support such triggers.

c.    WIMAX forum inter-ASN MM would use MIH triggers along with other information to make

inter-ASN mobility decision.  

 

Basically I see the main work is being done by 802.16g upon request from .21 because it is the one who is making necessary changes to support various triggers required for L3 mobility management.  Please comment if I missed anything here.

 

Regards,

Ajoy

Parkash:

The answer is mixed. Yes R3MM (inter ASN) is within NWG scope indeed. However, triggers and information from MIH could be part of the MM decision process. It will not heart to have the MM receive MIH info if such available. Could MM execute R3 mobility w/o MIH info or triggers, yes. Could MIH help MM, also yes.

Ajoy: Having said the above, WiMAX NWG will address inter technology HO in release 2. It may be more practical to deal with MIH during that period (mid 2006).

Hi Prakash,

 

 

Which working group of 802.16 is working to define triggers for inter-subnet L3 handoff? I am not sure

if 802.21 is defining inter-technology handoff itself. Rather it is defining triggers, information elements

etc for higher layer mobility management protocol.

Ajoy

Intra 802.16 handovers are being addressed in various 802.16TGs and the WiMAX Forum. So I do not see a need for .21 to work on .16 handovers.

If .21 identifies specific deficiencies, then perhaps we can figure out where to add/fix them.

802.21 mostly applies to handovers across heterogeneous technologies such as 802.11, 802.16, etc. and Cellular systems.

However intra 802.11 handovers i.e. handovers between 802.11 ESSs are also within scope of 802.21.

 

Along similar lines I was wandering if 802.21 also needs to address intra 802.16 handovers (in any form).

Did not see anything specific to that effect in the PAR or 5 Criteria documents, so my initial understanding is “no”.

 

Any clarifications from Chairs or even other folks welcome.

 

Best Regards
