Specialist Task Force 473: 
Alert Message Encapsulation

Who we are:

Team Leader: Matteo Berioli, Berioli Services,

Team Members:        Sara Jayousi, CNIT,
Josef Rammer, Dr. Rammer RM e.U.,

What we do:

We are defining how alert messages can be efficiently transported over satellite links. This is a challenging task, given the particular requirements of alert messages that have to reach many citizens, or a wide set of professional receivers in a reliable manner, and the characteristics of the traversed channels, that may be very narrow-band or subject to fading. The approach is to design a novel encapsulation protocol that could work well with widely established alerting solutions (e.g. based on the Common Alerting Protocol) and over existing networks, for instance over satellite navigation broadcast links.

For more details, see our Terms of Reference

Why we do it:

Current mass alerting systems rely on trustable but inefficient technologies (sirens, road displays, radio and TV broadcasts). The required technological upgrade will benefit from the proposed standardization activity, guiding towards interoperable solutions from different manufacturers and for various alerting platforms. Emergency warning will also become more efficient and effective.
The transmission of alert messages over satellite navigation systems, like EGNOS, or GALILEO, will be considered. The upcoming navigation services offered by GALILEO will enable new potential applications which take advantage from the new positioning and data broadcasting capabilities offered by the new system. The proposed standard is conceived to be fully integrated with the data-bearing navigation services (PRS and CS) available with the GALILEO system. PRS applications will be used by emergency services, for critical transportation, in the energy sector, and for telecommunication purposes. This will ease and promote the development of a large variety of location-aware applications and devices, using commercial GALILEO receivers. The mass production of navigation chipsets will allow the integration of alert data messages reception into different devices (road panels, vehicular information systems, smartphones), also creating valid opportunities for the related European industry.
Stakeholders from the industry will benefit from this standard for the rapid prototyping of new products related to the emergency context. The National and European Authorities will find a way to harmonize alert systems in Europe reducing equipment costs, increasing efficiency, and the timeliness of mass alerting at European and National levels.

How we do it:

We work in cooperation with the SES SatEC WG, as well as in liaison with the EMTEL Special Committee and the Human Factors Technical Committee in ETSI, whose activities are also related to alerting systems. Alert messages may have to be transported over different links, over classical satellite communication systems, but also over satellite navigation systems; for this reason different groups/organizations will be considered: e.g. Euroalarm, the Forum for Public Safety Communication Europe (PSCE), Galileo Joint Undertaking, ESA EGNOS.
