Special Committee (SC) Emergency Telecommunications (EMTEL) Activity Report 2020

Chair: Cristina Lumbreras, EENA

Responsible for identifying the operational and technical requirements of those involved in the provision of emergency communications, for conveying these requirements to other ETSI committees and for liaison with other organisations involved in this field

Our Emergency Communications Special Committee (SC EMTEL) is focused on the access to emergency services through different media, data transmission to public safety answering points, networks and IoT (Internet of Things) devices in the provision of emergency situations and in the context of the European Public Warning System.

Much of our work is centred on Next Generation 112 (NG 112) services, involving communications between IoT devices in emergency situations. The scope of this work includes the architecture, core elements and technical interfaces for network-independent access to emergency services.

In 2020 we published our new Technical Specification [TS 103 698] on the Lightweight Messaging Protocol for Emergency Service Accessibility (LMPE). This defines a SIP SIMPLE based Instant Messaging protocol for Emergency Service accessibility using NG112 core services.

Also in relation to NG112, our work considers test cases and scenarios for interoperability testing of the architecture and core elements for independent access networks. Examples of scenarios include location based and policy-based emergency call routing, network or handset derived caller location (e.g. AML) as well as legacy, IP, enterprise/campus, and IMS based access networks. We accordingly published two parts of our NG112 conformance test specifications. The first part [TS 103 650-1] covering Protocol Implementation Conformance Statement (PICS), Test Suite Structure and Test Purposes (TSS & TP); the second [TS 103 650-2] covers Abstract Test Suite (ATS) and Protocol Implementation eXtra Information for Testing (PIXIT).

As part of the committee’s ongoing activities we revised our specification [TS 103 478] on the Pan-European Mobile Emergency Application (PEMEA).

Reflecting recent technology developments in the IoT, we updated two existing specifications  [TS 102 181, TS 102 182] on requirements for communications from and between authorities/organizations to individuals, groups or the general public during emergencies. These revisions reference work in 3GPP SA6 on MCX communication, and in TC SES / SatEC on reference scenarios for the deployment of emergency communications. They also consider results from STF 555.

SC EMTEL liaises with organizations outside ETSI such the Electronic Communications Committee of the European Conference of Postal and Telecommunications Administrations (CEPT ECC) and the Global Standards Collaboration (GSC). It also follows the activities of organizations including the US National Emergency Number Association (NENA), the Telecommunications Standardisation sector of the International Telecommunication Union (ITU-T), and various fora and consortia, including the Internet Engineering Task Force working group on Emergency Context Resolution with Internet Technologies (IETF-ECRIT).

In cooperation with the European Emergency Number Association (EENA) and NENA: The 9-1-1 Association, we planned the fourth NG112 Emergency Communications Plugtests™ event, taking place from 22 February to 5 March 2021. Based on use cases developed by ETSI, EENA and NENA, the test programme offers a unique opportunity for vendors of emergency communication equipment to test their product against different implementations and scenarios.
