0  IntroductionWord‑p. 6

Non-voice communication such as text messages and instant messaging via wireless devices has been very successful and continues to expand. Many consumers assume that they can utilize these types of non-voice communications as mechanisms to communicate with emergency services whenever emergency assistance is required. Such mechanisms currently do not exist. The Emergency Services community has a desire to have multimedia emergency services supported with the same general characteristics as emergency voice calls.
Currently, TS 22.101 service requirements for emergency calls (with or without the IP Multimedia Core Network) are limited to voice media. The Non-Voice Emergency Services is intended to be an end-to-end citizen to authority communications. The Non-Voice Emergency Services could support the following examples of non-voice communications to an emergency services network:
  1. Session based text messages (which does not include SMS) from citizen to emergency services
  2. Session based and session-less instant messaging type sessions with emergency services
  3. Multi-media (e.g., pictures, video clips) transfer to emergency services either during or after other communications with emergency services.
  4. Real-time video session with emergency services
In addition to support the general public, this capability would facilitate emergency communications to emergency services by individuals with special needs (e.g., hearing impaired citizens).
NOVES does not preclude the support of specialized emergency services and devices designed for the special needs communities. The requirements defined for the support of specialized emergency services and devices for the special needs communities may differ from the NOVES requirements.
NOVES as defined in this document focuses on Next Generation Network (NGN) technology and does not include legacy messaging services, such as Short Messaging Service (SMS). In addition, NOVES only supports human initiated devices.

3.1  Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Next Generation Emergency Service:
An IP-based emergency service.
Non-Voice Emergency Services (NOVES):
NOVES are next generation emergency services with media other than, or in addition to, voice that utilize trusted applications in support of non-voice communications between citizens and emergency authorities. NOVES provides secure transport of messaging and media content, and location information of the reporting device to emergency authorities, in addition to providing two-way voice emergency communications between citizens and emergency authorities (e.g. - PSAPs). NOVES does not preclude the support of specialized emergency services designed for the special needs communities including non-support of two-way emergency voice communications.
Session based NOVES:
Session based NOVES are next generation emergency services using real-time session-based text and multi-media.
Non Session based NOVES:
Non-session based NOVES are next generation emergency services using a combination of media types such as text messaging, graphics, animation, audio and video etc.
NOVES Device:
A NOVES device is a next generation end user device (e.g.- wireless LTE device) that utilizes trusted applications to provide secure transport of messaging and media content, and location information of the reporting device to the emergency authorities, in addition to two-way voice communications between citizens and emergency authorities (e.g.- PSAPs). A NOVES device does not preclude the support of specialized emergency devices designed for the special needs communities including non-support of two-way emergency voice communications.
