Friends;
Mark Wood, DRCF.

I will not be participaing in the IETF with my ITU 'hat' on, rather as Pro
Bono advisor to the Disaster Relief Communications Foundation, (DRCF). The
ITU are not attempting in any way to infuence the final outcome of the
IETF deliberations on the matter of Authority to Citizen communications.

The ITU-T SG2 [Naming and Numbering]  work is focused solely on the matter
of "Multicast Address Harmonisation for Civiv Purposes", at the request of
its member states, and does not seek to change any of the standards that
the 3GPP maintains.

IP technologies are fundamentaly different to those used in 2G, 3G and 4G
mobile networks, many of the challenges and solutions do not directly
translate to IP, so detailed comparison of the access layer bearers is not
my intention.

But I am aware of their detail down to bit level, so I can contribute some
of my knowlege and experience of that if anyone asks me to, or you can ask
a 3GPP expert to explain it to you.

However during my 12 years of experience with public warning, and
especialy with my experience as convener of the ITU liason on the matter,
I have learned that the whole subject has many Techncal, Regulatory,
Political, Social, Commercial and Diplomatic overtones, which we at ITU
had to understand over the course of many years.

If you would like me to talk about some of them, as a matter of informaton
for your kind consideration, then I would be gladly willing to share with
you some of the lessons that we have leared so far. Doing so may stimulate
your own discussion and save years of time in understanding which factors
may or may not have any baring on your own deliberations.

Understanding some of the  issues handled by others may help you avoid
repeting mistakes, or not, at your discretion.

However I repeat; the ITU are not seeking to infuence the IETF in areas of
IETF's obvious competence.

Warm regards,  Mark Wood DRCF
