The use of mobile technologies in Public Alerting

This paper aims at describing the state of the art regarding the use of mobile technologies in Public Warning Systems (PWS) and introducing Intersec Alerting Solution.

Context: two dominant technologies for alerting coexist on the market

The huge adoption of mobile phones all over the world is providing a great opportunity for governments to better inform population during emergency situations, by sending a message to all handsets that are in the hazardous zone. In order to do so, several technologies can be used.

In 2006 the European Telecommunication Standards Institute (ETSI) produced a report on mobile-based technologies that became the basis for an emergency messaging service. The report suggested several mobile technologies (Paging, CBS, SMS, TV, MBMS, MMS, USSD, Email, IM Service) and concluded that Cell Broadcast Service (CBS) and Short Message Service (SMS) were among the most suitable technologies for delivering a mobile-driven PWS.

How CBS became the standard

Further 3GPP & ETSI reports define more precisely the requirements for a PWS. Although they do not specify which technology has to be used, some CBS characteristics make it particularly interesting:

It uses a dedicated channel, allowing the delivery to millions of people in seconds, without being affected by network congestion (and without causing it). On the contrary, SMS use shared signaling channels and network congestion may lead to delays in delivery.

It can be displayed automatically with no user interaction and with a special ringtone, making the CBS message instantly recognizable as an alert (unlike the SMS).

When Japan decided to implement its Earthquake and Tsunami Warning System (ETWS) in 2007 it chose CBS for its delivery speed. This aspect is indeed very important for earthquake warning, where the alert message has to be sent in the short time lapse (a few tens of seconds) between the first non-destructive waves and the real earthquake. The Japanese system was then formalized in 3GPP standards, setting the rule for future implementations.

Several countries have since followed Japan’s example and chosen CBS for their PWS, including Israel, Chile, the USA, Romania, Lithuania, Philippines, New Zealand, South Korea, Peru, Thailand,  United Arab Emirates and the Netherlands.

CBS limitations

However, CBS has one main limitation: it is not supported by all handsets and even when it is supported it requires a manual configuration from the user.

This means that it does not reach everybody. During a test conducted in the Netherlands in November 2013 many people complained on Twitter that they did not receive the message .

This was supposed to be a temporary issue but cell broadcast penetration among handsets proved to be slower than expected. As of today it is still unclear how many years will be needed before all handsets can receive CBS messages. Based on Homeland Security study on WEA mobile penetration , we can assume that from the time a country decides to implement CBS alerts, 5 to 10 years will be needed before a large percentage of the population (more than 90%) have a compatible device.

Moreover, the need for a manual configuration remains an issue, as a lot of people are still not familiar with the procedure, which can further postpone the date at which 90% of the population will actually receive the alerts.

SMS, historically second-best choice, has recently been chosen by several countries

For that reason and following recent technology improvements more and more countries are considering geo-targeted SMS as a viable option for mass-alerting. And that is how SMS, despite its limitations, is coming back on stage, maximizing the reach of the alerting campaign as all handsets natively support SMS, without requiring any configuration.

Australia was the first country to make this choice, in 2009, and today claims a rate of 93% of successful SMS delivery . SMS systems have also been deployed in Norway and Belgium, and a trial in the UK in 2013 concluded that location-based SMS was the preferred solution over CBS.

SMS overcame CBS

In addition to solving the reach issue, SMS offers several advantages, such as:

  • It is less expensive and quicker to implement, as much of the infrastructure is already in place,
  • It gives a proof of delivery, insuring governments and MNOs against all liability in case of accidents,
  • It unlocks the possibility to personalize the message (e.g. the language) on a per-user basis.

However, SMS keeps the aforementioned limitations:

  • Network congestion may lead to delays in delivery,
  • A standard SMS may not be identified immediately as urgent

CBS-SMS comparative analysis: what to keep in mind

The following table summarizes the main advantages and drawbacks of the two technologies:

CBS and SMS are often considered as rival technologies for PWS. However, a closer look at their ad-vantages and drawbacks reveals some complementarities, meaning that using them together will solve most issues that each technology faces when used alone.

Intersec approach: combine CBS and SMS to maximize both reach and delivery speed of PWS

Intersec approach can be summarized in two key points:

  • Combine CBS and SMS channels to maximize both reach and delivery speed with advanced network congestion prevention mechanisms
  • Take advantage of our unique geofencing technology, which is both real-time and mass-scale, for advanced population movement monitoring and increased efficiency in crisis management.
    Intersec has a proven track of records for Cell Broadcast and Igloo technologies in about 15 countries covering several hundred million people. Major deployments include various affiliates in Orange Group, Weve (joint venture of EE, O2 and Vodafone in the UK) and Telefonica Group in Europe and Latin America.

Maximizing reach & time to inform everybody effectively

Intersec multi-channel approach allows to maximize both reach and delivery speed by:

  • Using CBS to inform CB activated handsets rapidly. Intersec CBS is particularly relevant in a context of PWS: it is network agnostic (2G/3G/4G), PWS standards compliant (CAP/ATIS), and includes smart network congestion mechanisms.
  • Sending SMS as a complement: first to people with a non CB compatible device and then to CB compatible devices in case CB was not configured or activated.

Moreover, Intersec solution uses real-time monitoring of subscribers density and statistics of successful delivery reports to optimize delivery timeline and which areas get alerted first. This way the delivery can benefit from the additional word of mouth effect, accelerating efficiently the spread of the alerting.

Maximizing successfulness of SMS delivery

Network congestion may cause delay in SMS delivery during emergency situations. Intersec solution implements several features designed to minimize this effect, such as:

sms delivery

  • Using our Plateforme as a cache to offload network elements such as HLR,
  • Leveraging on subscriber connection state to maximize First Delivery Attempt success,
  • Prioritizing the SMS alerting traffic over the user P2P traffic,
  • Using real-time monitoring of RAN / core network nodes load information to ensure SMS delivery across congested networks.

Increasing campaign effectiveness

GeoSafe offers two unique capabilities that allow increasing the effectiveness of an alerting campaign:
The ability to manage lists of people, to know who has been alerted,
A mass-scale real-time view over the location of all subscribers on the network.

These features increase crisis management efficiency by:

  • Sending personalized messages in the language of the subscriber,
  • Optimizing the evacuation plan by sending appropriate directions to different groups of population in the same area,
  • Monitoring the effects of the campaign in real-time (using heat maps and statistics about population movements) to adapt quickly to changing circumstances.

It also allows to communicate with the alerted population after the crisis even if they have left the area, which was identified as a key issue by Francis Markus – East Asia spokesperson for the International Federation of Red Cross and Red Crescent Societies (IFRC) – who commented after the Fukushima event in Japan that “the conditions faced by those displaced were made worse by them not knowing when they can return.”
Intersec provides a consolidated future proof solution, which:

  • Is 100% telco grade, highly performant and supports virtualization,
  • Maximizes the reach towards the population,
  • Integrates unique and compelling functionalities for PWS for increased crisis management and population safety.
