2. Advanced Mobile Location in Norway
• The story behind AML in Norway
• The deployment
• Challenges we met
• How AML is working in Norway
• How does it affect the emergency services today
• Recommendations for other authorities deploying AML
• Success stories

3. Emergency services in Norway
• Three emergency numbers
– 112 (Police), 110 (Fire and Rescue) and 113 (Ambulance)
• Emergency medical services
– 16 Emergency medical communication centers in Norway (113)
– The call takers are usually nurses. The dispatchers are usually EMTs
• Community emergency medical communication centers (116117)
• Police and fire to be co-located all over Norway
• In Bodø all three are co-located

4. The story behind caller location in Norway
• Used by Emergency Services since 1995
• Central hub from 2007 (NRDB)
– Number portability, caller information (name, address) and caller location
– Based on base station information from the mobile networks (Cell ID).
– Available for call takers on
every emergency call
with no delay
– Owned and financed by
the mobile network
operators.
– Regulated by the
Norwegian Communications
Authority

6. Why did we decide to deploy AML?
• Having an accurate position of the caller is important.
• Not all citizens will download an app, and not all will use the one they downloaded
• Reduce the time spent to pinpoint the exact street address or position

7. Deployment
• Existing central HUB.
– XML-based API already in place, with field for GNSS-position
• We had support by national authorities
• Technical discussions
– With Google and Apple
– How to receive the AML-information
– From mobile to hub (data SMS), and from hub to control room (XML)

9. Deployment
• Dialog with the mobile network operators
• Legal challenges
– Google, Apple, mobile network operators
– The Norwegian Data Protection Authority
• Make changes in the telecom regulations related to emergency calls
• Implement necessary basic support in the GIS systems for a pilot project
• Enhancements in GIS systems, show base station and GNSS-position
10

10. Deployment
11
• Current configuration for Google Android

11. GIS implementation
12
• Always display AML-position
together with the base station
area (cell ID)
• To verify that the AML-
position is correct
• Inside positioning can be
difficult, especially if the
mobile user is inside a building
with no GNSS-coverage or on
a moving object with WIFI, for
instance a train or a boat.

12. Challenges
• End to end responsibility and support for the AML solution
• Mobile network operators believed current legislation prevented them
from passing on such accurate positions.
• Legislation and regulations had to be changed by the government
• Implementation in all the map systems in use
• Support for all three emergency numbers in Norway
– 112 (Police), 110 (Fire/Rescue) and 113 (Ambulance)
– Google supported all
– Apple none during rollout, but testing in progress
for emergency number 112.
– We hope they will implement support for all three numbers
13

13. Challenges
• Some AML-positions shown are
several hundred meters off
– Currently the map shows only first
position received from the phone
• There was a low number of
emergency calls with AML, only
20%. We expected around 40%
• Suddenly rose to 40% a week ago.
To be investigated.
• AML for emergency SMS is
activated, but currently not
supported by the receiving system

14. Recommendations for other authorities deploying AML
• Small project group
– With representatives from emergency services, IT and authorities.
– We had representatives with IT and operational knowledge from the
directorates together with technical and legal resources from the Norwegian
Communications Authority and the hub (National reference database).
• Use or create a shared hub for handling caller location for all the
emergency control rooms
• Look at the regulations, change them if needed
• Cooperate with the mobile network operators and map vendors
– Tuning of the map user interface for the call takers
– Show AML-position together with base station for verification

16. Success stories
17
• Accident in the mountains with
tourist
• AML position immediately
available with 10 meters
accuracy
• Call taker could focus on life
saving first aid and not the
location
• Other stories with cars, people in
their cabin, with no address
• Callers in distress, can’t
remember even the color on
their house
