Negotiating Human Language in Real-Time Communications
draft-ietf-slim-negotiating-human-language-20
Abstract
Users have various human (natural) language needs, abilities, and
preferences regarding spoken, written, and signed languages. This
document adds new SDP media-level attributes so that when
establishing interactive communication sessions ("calls"), it is
possible to negotiate (communicate and match) the caller's language
and media needs with the capabilities of the called party. This is
especially important with emergency calls, where a call can be
handled by a call taker capable of communicating with the user, or a
translator or relay operator can be bridged into the call during
setup, but this applies to non-emergency calls as well (as an
example, when calling a company call center).
This document describes the need and a solution using new Session
Description Protocol (SDP) media attributes.
