Article 110 of the European Electronic Communications Code (EECC) mandated all EU countries to operate a public warning system that can send geo-targeted emergency alerts to all mobile users located in the affected area in case of an emergency. 

Telefonica O₂ Germany was looking for a partner able to deploy Cell Broadcast technology in a collaborative manner, in full compliance with data privacy regulations, and in alignment with the EECC requirements.


  • As the European Union's leading public warning system provider and with 19 years of experience in the telco industry, Intersec had demonstrated its ability to deploy nationwide public warning systems at Tier-1 operators

  • Intersec partnered with Telefónica Ingeniería de Seguridad (TIS) to ensure seamless and smooth integration in record time

  • On 2022 Nationwide Alert Day – Warntag – Telefonica successfully broadcasted two alert messages - in German and in English – from the Federal Office for Civil Protection and Disaster Relief in just a matter of seconds, confirming the high-end performance of the solution

The high level of expertise and experience of the Intersec professional services team enabled a smooth integration in record time. This success is a testament to the relevance of this partnership, where Intersec's expertise and ours work together in the best possible way.

In the heat of August, with temperatures over 40°C, and following a breakdown in the ventilation system, a fire broke out in a factory. The industrial site produces various chemical products for the fine perfumery, detergent and lubrication markets. Rapidly, the fire became uncontrollable. Toxic chemicals began to escape. A regional crisis unit was set up and the Prefect launched a crisis management operation. 


On a national level, a location-based SMS was immediately triggered by the Prefecture in surrounding regions to all citizens exposed to the risk using FR-Alert.On a local level, the mayors of the affected cities decided to refine the instructions for the inhabitants closer to the plant and sent 3 messages using Trela: 

  1. The 1st one targeting the people living less than 5 km away instructing strict confinement, 
  2. The 2nd one to a buffer zone to ask them not to go near the plant, 
  3. The 3rd one to a predefined group of parents to ask them not to approach the schools until the end of the alert

Trela then replicated the messages on the cities’ social networks and transmitted through voice calls the messages to people who did not have a cell phone, mostly elderly people.

Cell broadcast is not enough

Why Cell Broadcast?


Cell Broadcast is an instrumental technology when dealing with Early Warning and Emergency Warning in critical or degraded situations, or when time is of the essence.

The alert text message is issued by a Cell Broadcast Entity (CBE) and broadcasted by the Cell Broadcast Center (CBC) to all mobile devices in a defined area. Such short messages (SMS-CB) benefits from a specific display and possibly a notification accompanied by a particular ringtone, to be recognized instantly as an alert.

The Cell Broadcast Service (CBS) is a powerful technology: one may reach millions of devices in a few seconds even if the operators’ networks are congested and in full privacy data protection compliance as the phone numbers of the subscribers are not used in the broadcasting operations.

Why Location-Based SMS?


First of all, SMS channel offers the perfect compatibility level, being supported by 100% of mobile network and phone generations all over the world for 30+ years.

Leveraging on a genuine real-time cellular geolocation technology, public warning via LB-SMS unlocks dynamic and adaptative public warning strategies, to cope with any situation and throughout the crisis management timeline.

This great flexibility is typically expressed in the wide variety of targeting scenarios:

  • address the SMS alert to all subscribers inside or entering the impacted area, optionally add devices that were recently in the zone
  • send distinct SMS content to inbound roamers with specific information in their language
  • alert subscribers roaming abroad of a particular situation there, or in home country
  • recontact people afterwards, even if there are not anymore inside the impacted area, to provide follow-up instructions and situation updates, and return-to-normal or post-event information.

Moreover, thanks again to the SMS technology standard, managing authorities can monitor in real-time the effectiveness of the alert dissemination within the population through aggregated and anonymized delivery statistics.

Toward a multichannel approach


Intersec strongly believes that governments and mobile network operators should adopt a multichannel approach in order to maximize the chances of disseminating information to as many people as possible in case of an emergency. Possible channels include using people’s phones, but also sirens, social media, TVs & radios, emails, variable message signs…

Combining these technologies dramatically increases the efficiency of the system, and accelerates nationwide messaging broadcast, while ensuring full interoperability with existing services.

The choice to combine certain technologies depends on various factors, including:

  • the nature of the event
  • the number of people to be reached
  • the required speed to communicate
  • the state of the mobile networks
  • etc.

So, which technologies to use when facing a tsunami, flash floods or a dirty bomb for example?  Let's look at some concrete examples in this infographic.

Enriched by fast data and AI-enriched features

  • Mass-scale real-time geolocation stack to manage 10B+ of points per day
  • Fast multi-criteria targeting engine to generate any type of alert campaigns, from the simplest to the most complex
  • Extensive PII data protection, with strong anonymization process, non reversible
  • Real-time population heatmaps computed from aggregated statistics, derived of anonymized location data
