Re: [STDS-802-16-MOBILE] Harmonization of



Itzik and all,

I strongly disagree with this approach.  As far as impacting state machines,
I think you are dramatically overstating the effect.  Indeed, I think it far
easier to implement RNG-RSP HO transaction optimization flags, specific for
each step of network re-entry, than to use some type of defined arbitrary
logical coding scheme where HO optimized profile 'a' looks like this, and
'b' looks like this.  HO optimized profile sets require a different set of
procedures for each optimized profile, divergent and independent SDL models,
and you account for each different profile separately.  Thus, if you add a
new profile, you have to add a new process.  Messy and unecessary.  HO
transaction optimization flags represent a simple modification to existing
HO SDL (i.e. If can skip SBC-REQ/RSP, skip it, Else process SBC-REQ/RSP).
And support of the HO optimization flags would by inference support ALL
optimized HO mechanisms that achieve optimization through minimizing network
re-entry handshaking, whether those optimized HO mechanisms are currently
defined or are to yet to be envisaged.  Also, there is nothing in HO
transaction optimization flags that keeps you from padding multiple
unsolicited RSP messages into a single frame, just as you suggest for HO
optimized profiles, all other considerations being equal.

Sorry about not being more available over the last two weeks, but have been
traveling and completely buried.  My time will improve after returning to
the States tomorrow.

Thanks,
Phil
