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.
