RE: Context Transfer Extension to Cellular-IP v01

Hi John,

Thanks for your comments about the draft. I will make this corrections
on the
next update.

By submitting this draft we are not by any means undermining the work of
the 
Context Transfer Team. In this draft we are demonstrating how the
handover 
protocol could be modified to transfer the state information which is
especially 
suitable in cases where the mobility protocol makes use of a central
entity 
(Using cellular-IP as an example).

We believe that when such a mobility protocol is used it may be more
appropriate
to utilise the existing message exchange rather than to have a
specialised 
Context Transfer protocol. 

Cheers,

Mike

        Hi all, 

        The Internet draft below, proposes a Context Transfer Extension
to 
        Cellular-IP. 

                Title           : Context Transfer Extension to
Cellular-IP 
                Author(s)       : M. Georgiades et al. 
                Filename        : draft-georgiades-seamoby-ctecip-01.txt 
                Pages           : 13 
                Date            : 2003-7-1 
          
        This Internet draft enhances cellular-IP mobility protocol with
a 
        Context Transfer mechanism aiming to further optimise the
handoff 
        operation in mobile networks. Within a cellular-IP domain,
during the 
        handoff from one cellular-IP base station to another,
cellular-IP 
        packets could be  used to initiate and transfer authorised
context 
        from the previous cellular-IP base station via the cellular-IP 
        gateway to the new cellular-IP base station. This draft presents
how 
        the context transfer extension introduced could facilitate in 
        reducing latency and packet loss by avoiding the signalling
required 
        between the mobile node and the new base station  in 
re-establishing 
        the desired state information.
