The present document describes new use cases and potential requirements applicable to Public Warning Services for
UEs with diverse form-factors whose user interface is different from the conventional mobile phones; and
UEs that are defined by applying 3GPP system to non-ICT industry businesses (e.g. vehicles or machines such as
IoT devices or robots) and have the different UE role from what 3GPP has traditionally assumed.
In addition, it considers the improvement of the understandability of the PWS message e.g. displaying language
independent or graphical content to users, especially foreigners who might not understand the language used in the text
or people with physical disability who may be sight impaired and unable to read the text. So it deals with user interface
related potential requirements to address the presentation of the warning message considering circumstances such as
language being used (e.g. international roaming scenario where the user does not understand the local language) or
users with disability (e.g. people with vision impairment).
The present document does not cover use cases or potential requirements for US WEA and Japan ETWS so the results
of this document are not applicable for US and Japan. This document considers national variants of EU-Alert and KPAS
related service scenarios and potential requirements.
