RE: [802.21] MIH commands for handover

Hi Sanjib,
 
There is no MIH protocol defined for reactive modes e.g. MN_HO_Candidate_Query* is only predictive/proactive.
 
In FMIP, PrRtSol/PrRtrAdv are exchanged (not in critical path) on old link regardless of predictive or reactive but MN was not able to complete the FBU/FBA on the old link. The reactive mode is then to exchange FBU/FBA on the new link. But the NCoA info is already available before you arrive at the new link. OTH, if you want to discuss an adverse situation where MN has no information of new link, then a router discovery must happen with RtrSol and RTrAdv before sending FBU.

Hi Srini

Well I agree with u that NCoA can be sent over serving link, this is wat the
predictive mode as far as my knowledge is concerned...
how will you send NCoA information in case of reactive mode of
handover.....
In that scenario either the L2 messages should carry IP information or
MIHF should do the same. ofcource this in turn needs changes to MIH
message parameters...


thanks & regards
Sanjib
