Body
During the ITU-T Q5/13 NGN GSI meeting held in Geneva from May 11-22, the
group noted that the IETF-74 meeting held a BOF session on Authority to
Citizen Alerts (ATOCA). Q5/13 has developed two Recommendations, Y.1271 and
Y.2205 addressing Emergency telecommunications related definitions and
considerations. In particular, Y.2205 clause 9 “Mechanisms and Capabilities
supporting some aspects of early warning in NGN” discusses alert systems, and
the common alert protocol. In developing a charter for your proposed working
group on ATOCA, we would like to bring to your attention the emergency
telecommunications related definitions in Y.1271 and clause 9 in Y. 2205 that
may be useful in the drafting of the charter for ATOCA. 
We are currently working on a revision to Y.2205 and we would be interested in
expanding this clause in the future to reflect relevant aspects developed in
this IETF proposed working group. We wish to be informed of the progress of
the working group deliverables i.e. RFCs so that we can incorporate
appropriately in our future versions of Y.2205. 
In addition to these two attached Recommendations, please note that other
ITU-T study groups have developed Recommendations related to Emergency
Telecommunications. As such, members from different administrations and
service providers have discussed/resolved terminology and other issues related
to differences and similarities in different countries on this topic. We would
be happy to provide you our decisions and understanding to facilitate your
further efforts in IETF. Please let us know if we can be of further assistance
so that you can benefit from our experiences.
