SR 784.101.113/1.3 Emergency call requirement

These technical and administrative regulations apply to all telecommunication service providers who offer the publically available telephone service. They specify the routing of emergency calls from the calling fixed network or mobile telephone subscribers to the alarm centres of the police, the fire brigade, the Samaritans, ambulance services and helplines for children and young people. They regulate how an emergency call at the interconnection interface is forwarded from one telecommunication service provider to another and how identification of the caller's location is transferred to the emergency services. These regulations exclusively concern emergency calls, i.e. calls to numbers 112, 117, 118, 143, 144, 145 and 147.

Edition 17 : Routing and location identification

Better location identification for emergency calls

As of 1 July 2022, emergency calls made from mobile phones must transmit more specific caller location information than before. This applies to emergency calls, whether they were made from mobile phones or placed by vehicles in the event of a car accident. Thanks to the more accurate information, emergency services can organise their operations more quickly and efficiently.
