Hello,

ISSUE:

3GPP SA1 decided that eCall over IMS is required to solely tranfer MSD - see http://www.3gpp.org/ftp/tsg_ct/WG1_mm-cc-sm_ex-CN1/TSGC1_98_Osaka/docs/C1-162764.zip stating:

--------------

SA1 service requirements for eCall over IMS only consider emergency call and transfer of the MSD (which shall not exceed 140 bytes) as defined by CEN as the services to support.

--------------

According to section 2 of the draft, the scope of the draft is supposed to be limited to 3GPP and CEN scope:

--------------

2.  Document Scope

   This document is limited to the signaling, data exchange, and

   protocol needs of next-generation eCall (NG-eCall, also referred to

   as packet-switched eCall (PS-eCall) and all-IP eCall) within the SIP

   framework for emergency calls, as described in [RFC6443] and

   [RFC6881].  >>eCall itself is specified by 3GPP and CEN<< and these

   specifications include far greater scope than is covered here.

--------------

However, the draft content goes beyond it own scope since it e.g. defines the following actions:

-------------

   o  Play and/or display static (pre-defined) message

   o  Speak/display dynamic text (text supplied in action)

   o  Flash or turn on or off a lamp (light)

   o  Honk horn

   o  Enable a camera

-------------

PROPOSAL:

                Move text going beyond 3GPP and CEN requirements into another document.

Kind regards
