What does Android Emergency Location Service mean to you?

ELS (Android Emergency Location Service) allows governments, emergency infrastructure services, mobile network operators, give correct location details to 1st responders in case of emergencies

What exactly is ELS?

Android Emergency Location Service or ELS can be defined as an additional service sending out location straight from the from Android devices to different emergency services in case an emergency call is made.

How ELS works?

ELS makes use of similar location technologies as given to apps on any Android phone which includes GPS, cell, WiFi signal, and various Smartphone sensors so that it can gauge the correct emergency location outdoors as well as indoors.

Advantages of ELS

• ELS is enabled only when a user calls Emergency Services.
• ELS doesn’t need any specific updates, downloads or hardware
• The location data is transferred through Data SMS/HTTPS, and they both are open & OS-agnostic protocols.
• The location is calculated over the handset and then sent out to the emergency services
• ELS location tends to be correct and trustworthy as compared to cell tower IDs.

An EL is installed by Google partners in collaboration with various carries, mobile network operators, governments, and emergency infrastructure providers in a particular region or country.

The partner holds the responsibility to set up and maintain ELS Endpoint to obtain ELS location messages as and when a user gets in touch with an official, publicly known emergency number. The ELS is enabled when a partner builds the required ELS Endpoint.

How location is calculated by ELS? – Data flow & quality

Gauging location

ELS location details are sent once the user calls emergency services.
The location is gauged locally over the handset and sends out straight to the endpoint that the ELS partner maintains at his end. Well, Google will not attain any emergency location.

Location quality

Today, in many countries across the world only emergency call centers get a cell-based location along with the location radius based on the sequence of kilometers.

Endpoints- How the location is reported by ELS

To work fine ELS needs a minimum of 1 “endpoint” to get location details, nowadays it is SMSC /HTTPS server.

Well, the endpoint or endpoints get messages through ELS location data via an Android device that contacts an emergency number and sends out the details to the emergency call receivers in PSAP (Public Safety Answering Point. The partner is responsible to build and take care of the endpoint.

ELS support 2 different reporting ways to endpoint:

• Data SMS
• HTTPS Post

In emergency send your location

If you want the 1st responders to trace you faster, then simply call an emergency number.

If ELS (Android Emergency Location Service) is available in your region and on the mobile network you are using but you have not switched ON ELS, still, your phone would send out its location automatically using ELS.

In case ELS is turned off, still, the mobile carrier might send the location of your device while making an emergency call/text.
