[earlywarning] What problem is ATOCA trying to address?

["SENNETT, DEWAYNE A (ATTCINW)" <[e-mail]>]

It is not clear exactly what problem ATOCA is trying to solve.

The first item needed for alerting is a common alerting message. This has been defined as the CAP protocol which has been adopted by ITU. The current version is CAP 1.1 and version 1.2 is expected soon.

The second item needed is transport of CAP messages. Various techniques already exist and Brian Rosen has already introduced a draft into ECRIT to define how to deliver CAP via SIP.

The third item is distribution of the alert information. Various techniques already exist such as multicast, cell broadcast, MBMS, EAS, CMAS etc..

The fourth item is authentication and authorization of the alert origination. The functionality is country specific and these countries also have defined methods and procedures to address this.

So what item remains to be addressed by ATOCA?
