RE: [802.21] 802.21: Scope

Vivek,

 

I think 802.21 should address any inter subnet handoff. 802.16 / cellular inter-subnet handover should not be any different from 802.11 inter-subnet handoff.

In both cases higher layer protocol such as Mobile/IP will be required to perform L3 handoff. Also, please note that triggers are much more useful in case of

Inter subnet intra-technology handoff as you have only one interface so doing make before break handoffs without link layer trigger is difficult.

 

Regards,

Ajoy

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
