2. ETSI – SES – SatEC ETSI European Telecommunications Standards Institute 2 STF 473 Broadband Radio Technical Committees: …. Emergency Communic . (EMTEL) Satellite Earth Stations & Systems (SES) …. Working Groups: …. Satellite Emergency Communic . ( SatEC ) Satellite Communic . & Navigation (SCN) Airbus Group, Ministère Economie , Siemens AG, CNIT, …; techn . experts. Delegates:

3. 3 SES SatEC Objectives SES SatEC activities are currently focused on three topics: Definition of reference concepts for the use of satellite in disaster situations Use of satellite communications for restoring/establishing communication capabilities in a disaster area  STF 472 Use of satellite communications for public warning systems  STF 473 (M. Berioli , S. Jayousi , J. Rammer) STF 473

4. STF473 Objectives Define a powerful encapsulation scheme whose main purpose is to: Embed other alerting standards (e.g. CAP, POCSAG) to support transmission over satellite; Provide a multi-semantic representation of the alert, allowing the interpretation by automated devices with limited capabilities. Fit in the main SatCom and SatNav systems Provide enhanced capabilities such as: selective activation (based on space-time coordinates); an increased reliability by adapting to the traversed network; the possibility to work over unidirectional & bidirectional links ; integrity verification and sender authentication; … 4 STF 473

5. STF473 Deliverables MAMES = Multiple Alert Message Encapsulation over Satellite Outputs: an ETSI Technical Specification ( TS): “MAMES” an ETSI Technical report (TR ): “ MAMES Deployment Guidelines” 5 STF 473

6. Alerting Hierarchy and Notation STF 473 6

7. STF473 – Terminology Alert Message: any message containing alert information Alert Issuer: entity responsible for creating the Alert Message Alerting Device: receives the Alert Message MAMES Provider: creates the MAMES Frame MAMES Receiver: receives the MAMES Frame MAMES Frame = MAMES Header + MAMES Payload MAMES Payload: the encapsulated Alert Message(s) MAMES Agent: inside the MAMES Receiver; does MAMES encapsulation /decapsulation 7 STF 473

9. Overview of Current Alerting Techniques Basic Traditional Alerting Techniques Sirens , loudspeakers , public displays , any visual / audio signals Alerting Techniques Based on Broadcast Paging (e.g. POCSAG), radio broadcast, TV broadcast Alerting Techniques Relying on Interactive Personal Devices Terrestrial networks, mobile networks, mobile satellite networks, Internet, Social Media 9 STF 473

ETSI/3GPP/IETF Standards 11 STF 473 Standards Organization Specification Scope of the Specification ETSI EMTEL (Emergency Telecommunic-ations ) TS 102 182 - Communications Requirements Operational and organizational requirements for alarm communication TS 102 900 - EU-Alert System requirements for EU-Alert using the Cell Broadcast Service (CBS) 3GPP Release 12 TS 22 268 - Public Warning System (PWS) requirements From the users’ and service providers’ points of view IETF ATOCA (Authority-to-Citizen Alert) (several Internet Drafts, all expired by now) Authorized transmission of alerts over the Internet

12. Candidate SatCom Systems STF 473 12   Key Characteristics Broadcast Fixed Alert broadcasting to fixed satellite receivers. Broadcast Mobile Alert broadcasting to mobile satellite receivers. Bidirectional Fixed Alert transmission (with return link) to fixed satellite terminals/gateways (e.g . VSAT). Possibility of acknowledgment. Bidirectional Mobile Alert transmission (with return link) to mobile satellite terminals (e.g. Inmarsat , Thuraya , Globalstar , Iridium ). Possibility of acknowledgment. Integration, see below

13. Candidate SatNav Systems Galileo Main Features: Global Coverage (30 MEO satellites) Developed for civilian use Independent European system, compatible/interoperable with GPS and Glonass New positioning and data broadcasting capabilities (new potential applications) Wide range of services EGNOS Main Features: Overlay system based on a network of ground stations and GEO satellites Enhances GPS/GLONASS Coverage over Europe, the Mediterranean Sea and Africa (3 GEO satellites) Already operational STF 473 13 Integration, see below
