Emergency call location

Accurate positioning and routing

Our emergency caller location intelligence combines multidimensional cellular device locating capabilities to provide emergency services with critical, certified, up-to-date information. It leverages on network-based plus handset-based location techniques and Advanced Mobile Location (AML) available data, to make the most of it in all circumstances, allowing first responders them to save more lives and protect better assets.

Fully compliant

As member of standardization bodies, Intersec implements norms and guidelines related to emergency call handling and caller location management: 3GPP, ETSI, EMTEL, ATIS, IETF, GSMA, GDPR, Etc.

99.999% uptime

When it comes to emergency calls, every second counts and failure is not an option. Carrier-grade “five nines” is of essence to mission-critical communications with public in distress.


18+ years telco expertise

Since its inception, the company is an ICT specialist. Intersec has built an extensive catalog of location technologies, allowing PSAPs and EROs to access certified and most accurate locations for the dispatch.

Robust and dependable

Fast, reliable and accurate caller location


When an emergency call is initiated, the Communication Service Provider (CSP) must identify the caller's location quickly and accurately. Identified location is instrumental for proper call routing and call setup with the relevant Public Safety Answering Point (PSAP) in charge of the situation in the concerned area.

Intersec emergency call handling solutions cover any type of networks and calls:

  • Mobile carriers, Fixed broadband carriers, Emergency service networks, ESInet/NGCS, NG112/911/xxx networks, …
  • Circuit-switched calls, Packet-switched and IMS calls, 2G, 3G, 4G, VoLTE, 5G, VoNR, WiFi calling / VoWiFi, VoIP, ...

Route the emergency call to the most relevant PSAP


Intersec passive location technology automatically retrieves access point identification of all handsets connecting to VoWLAN and looks-up for their corresponding location on a Wi-Fi access point location database. On the fly, the solution ensures their consistency, leveraging on the mobile network cell cartography. The operator therefore benefits from an emergency call solution fully compliant with local regulation, that provides trusted and reliable location for all emergency calls in any situation.

Reduce response time


To appropriately handle the situation, PSAPs also require access to the caller's location information. Another critical function of the original telecommunications operator is to report certified and most accurate locations with human-reading addresses to be used in dispatching and guiding emergency units to the exact site of the incident and minimizing vertical response time.

100% safe and sound

Emergency call initiation

Dialing an emergency number triggers call establishment and location acquisition procedures from telecom operator infrastructures, and AML from smartphones when available. Location estimates are derived by positioning algorithms from series of measurements and reference databases (Cellular topology, WiFi access points, A-GNSS/Galileo/GPS, Etc.).

Complement AML technology

AML (Advanced Mobile Location) is a significant step forward in ensuring people's safety in the event of an emergency but it has its limitations. In fact, tests provide confirmation that locations from handsets are provided in an average of 60-80% of cases. 

Always rely on best caller location

Supporting and complementing AML is key to leaving no one behind, whatever the phone, the network, and the situation. The best location accuracy comes from the combination and consolidation of multiple location sources, networks, and handset-based techniques.
