Evolution of text telephony

Text telephony is currently the basic means of
communication for many people with disabilities,
such as deaf people. The technology supporting
mobile telephony does not allow the extension
of traditional text telephony. For this reason, many
users substitute mobile text telephony by the use
of SMS messages, but they do not allow full
interactive communication, hence the need to
develop novel mobile text telephony services.

Since the next generation of text telephony in
Europe is under development, it is necessary
to establish basic design guidelines that guarantee
the quality of the service. "The recommendations
of the Nordic countries regarding functionality for
text telephony" section compiles criteria that
include mobility, interoperability, continuity,
accessibility from the internet, and availability of
relay services.

Diverse experiences have been developed to
provide mobile text telephony through the
access to internet servers. The section entitled
"Mobile & IP-based text telephony" shows
the deployment of such a service in Sweden,
while "Mobile text telephony based on GPRS
communications" explains the results obtained
by a Spanish project.
