ETSI Releases NG 1-1-2 Architecture, Location Specifications

21st Jan 2020

The European Telecommunications Standards Institute (ETSI) Emergency Communication Special Committee released two emergency calling specifications. 

ETSI TS 103 479 for next-generation 1-1-2 (NG 1-1-2), the next generation of European emergency services, specifies the core elements of the architecture for network independent access to emergency services, enabling interoperability of implementation for NG 1-1-2 access to emergency services.

The specified core elements support centralized mapping and routing functions for current and future emergency communications and operational requirements. The functional elements of the network comprise security measures and the routing capability to forward a call/communication received from any concentration point based on the caller's location to the relevant emergency services call center.

"I am very pleased to see that NG 1-1-2 standardization helps citizens communicate with the emergency responder organizations with a 21st century technology,” said Wolfgang Kampichler, ETSI’s emergency communications (EMTEL) rapporteur.

ETSI TS 103 625 covers the specific Advanced Mobile Location (AML) function, which is essential to provide the most accurate location of the caller. AML is already implemented in 22 countries worldwide following the publication of the first ETSI technical report TR 103 393.

More than 70% of emergency calls come from a mobile phone in Europe, and with AML, the phone's location capabilities are activated when an emergency number is dialed. The location obtained is then sent to a location endpoint managed by, or on behalf of, a national emergency service. These technologies can provide a location precision as close as 5 meters outdoors and averaging to within circular areas of about 25 meters radius for indoor locations, a significant improvement on existing cell coverage provided by mobile networks, which average circular areas of about 1.75 kilometers radius.

“If AML was deployed everywhere in Europe, it would save up to 7,500 lives and €95 billion (US$105.4 billion) in 10 years,” said Cristina Lumbreras, ETSI’s EMTEL chair. “AML is already implemented in all Android and IOS cellphones.” For an effective global implementation, the ETSI technical specifications for AML and NG 1-1-2 are paramount for the continued interoperability and location conveyance to the most appropriate emergency service, the organization said. The requirements to use handset-derived locations were included in the European Electronic Communications Code.
