Emergency mobile alerting systems gain momentum


European mobile operators are doing their bit to mitigate the effects of natural disasters or emergencies by making it easier to alert people of possible danger and find them if they are in trouble.

In something of a ‘big brother’ solution, European governments are asking mobile operators to deploy the infrastructure and technical solutions able to broadcast simple mobile messages to all their subscribers thereby improving emergency responses and public warning systems.

In conversation with Mobile Europe, Intersec CEO Yann Chevalier said: “European governments are increasingly mandating public alerting systems and paying mobile operators to support them. People need and want reassurance and to understand what is happening around them – it’s natural to receive mobile messages.

“Among the major challenges is not only determining which channel to use – SMS is familiar but could be slower in reaching the entire subscriber population than less well known mobile broadcast channels – but transmitting volumes of messages to large numbers of people.”

Governments want sustainable, interoperable systems that reach everyone, according to the CEO.

“France, Germany and Holland are running such systems already. The big question is who pays for it – mobile operators will only run alerting systems if governments mandate and pay for them,” he added.

Working with Brussels based NGO the European Emergency Number Association (EENA), Intersec is developing the necessary and efficient alerting systems.

It has combined real time location intelligence systems with geo-location capabilities thereby allowing governments and emergency services to collect network location data from the entire subscriber base.

As a result they can identify where people are going and learn something of how and where they are moving. Advanced geo-fencing capabilities identify and track people in real time as they move through or enter a danger zone.

EENA executive director Gary Machado said: “With the development of new technologies, mobile alerting solutions are one of the logical next steps in communicating effectively with a large number of people expeditiously.”

Using mobile broadcast technology or ubiquitous SMS, appropriate messages can be sent to large numbers of people in seconds regardless of the network to which they are connected.

Wireless Emergency Alerts FAQs


General Information

    1. What are Wireless Emergency Alerts?

       

      Wireless Emergency Alerts (WEAs) are free wireless notifications that are delivered to your mobile device as part of a new public safety system provided by Authorized Senders. They are designed to inform you of imminent threats to safety or missing persons alerts in your area.

      In order to receive WEAs, you must have a capable device and be located in an area (e.g., county) targeted by Authorized Senders to receive the alert.

    1. What information is typically included in a Wireless Emergency Alert?

       

      Wireless Emergency Alerts and updates will provide the following information:

      • Alert Category
      • Event Type
      • Response
      • Severity
      • Urgency
      • Certainty

      Note: Since these alerts are initiated by Authorized Senders, we will not possess any information beyond what is provided in the actual message.

      Back to top

    1. Why did I receive a Wireless Emergency Alert?

      Wireless Emergency Alerts (WEAs) are broadcast in a geographical area to  inform WEA capable subscribers  of imminent threats to safety or missing persons reports in your area. Authorized Senders issues these alerts only within strict guidelines and when they feel it is necessary to do so.

      If you received a WEA, you are within the geographical location being targeted by the Authorized Sender. You should review the information in the alert carefully and proceed as directed.

      Back to top

    1. Why did I receive a test Wireless Emergency Alert?

      Participating carriers are required to support monthly test alerts of the Integrated Public Alert and Warning System (IPAWS) system. Only specific persons within the carrier’s network employees, or within specific emergency response agencies should receive these alerts.

      If you are receiving test alerts, we thank you for your patience. The manufacturer of your device will soon release a silent, over the air fix to prevent further receipt of test alerts.

      Back to top

    1. Why did I receive multiple or duplicate Wireless Emergency Alerts?

      Devices compatible with Wireless Emergency Alerts (WEAs) are designed to reject duplicate alerts. Occasionally, Authorized Senders will issue updates to WEAs with new information and a new alert ID. These updates may be very similar to the original alert but will contain supplementary information.

      Back to top

    1. Will I receive local Wireless Emergency Alerts while roaming? Will I receive “home” alerts while roaming?

      No, only devices compatible with Wireless Emergency Alerts (WEAs) and operating within the targeted geographical areas should receive these alerts. Alerts are not delivered to any device outside of that area.

      Back to top

    1. How do I know if my device is capable of receiving government Wireless Emergency Alerts?

       

      Devices capable of receiving Wireless Emergency Alerts (WEAs) are marked on the retail callout card and at the Verizon Wireless equipment descriptions on line with the Wireless Emergency Alert Capable logo:

      They will also be specifically listed as WEA capable at all Verizon Wireless retail stores.

      View a list of Wireless Emergency Alert Compatible Devices. 

      Back to top

    1. Is there anything Verizon Wireless can do to make my device capable of receiving Wireless Emergency Alerts?

      Special software and hardware changes are necessary to support Wireless Emergency Alert capabilities. Unfortunately, these changes cannot be retrofitted to older model devices.

      Back to top

    1. I believe I was in a targeted geographic alert zone. Why didn’t I receive a Wireless Emergency Alert?

      Wireless Emergency Alerts are sent to cell sites providing wireless service to very specific areas. Your device may have been receiving service in a different area, or even from an adjacent area cell site, which was not targeted by the alert.

      Most WEA alerts will be re-broadcast several times to reach the maximum number of devices in the targeted area. Once a device has received an alert, it will not accept duplicate or identical alerts.

      Note: Alerts will only be received by capable devices. Without a capable device, you will not receive an alert even if you are within the targeted geographic location. Please see the “What are Wireless Emergency Alerts?” FAQ for a link to capable devices.”

      Back to top

    1. I have a device compatible with Wireless Emergency Alert. I am traveling today, but I did not receive an alert. Why?

      Wireless Emergency Alerts (WEAs) are geographically targeted. Only subscribers with WEA capable devices operating within the targeted alert zone will receive alerts.

      WEA capable devices operating outside of the targeted geographical areas will not receive those alerts.

      Back to top

    1. I have an SMS Block, why did I receive a Wireless Emergency Alert?

      Yes you will.  These WEA alerts do not travel over our Short Message System (SMS) and are not blocked by an SMS Block feature.

      Back to top

    1. Will I be charged for receiving a Wireless Emergency Alert?

      No, we provide Wireless Emergency Alerts FREE, at no charge to you.

      Back to top

    1. Can I opt out of receiving Wireless Emergency Alerts?

       

      There are three types of Wireless Emergency Alerts (WEA):

      • Presidential Alerts: about news of national authority concern
      • Imminent Danger Alerts: Severe and Extreme alerts about weather events and threat levels
      • Amber Alerts: about the disappearance of persons (minor or otherwise)

      You may change settings within your device to opt out of Imminent Danger and Amber Alerts, but you may not opt out of Presidential Alerts.  You may find instructions for your specific device at the Verizon Wireless equipment site

      To manage your preferences for specific alerts, go to the WEA application in your device and select and save your preferences. See your device manual for instructions.

    1. I’ve received a Wireless Emergency Alert. What should I do to ensure my safety or obtain additional information?

      Review the information included in the Wireless Emergency Alert (WEA) that you received, and follow any instructions that may be listed. Authorized Senders may also release updates to WEAs with further information as needed. Please watch for subsequent updates, and review them carefully for new details.

      Note: Because these alerts are initiated by Authorized Senders, Verizon Wireless does not have any information beyond what is provided in the actual message.

      Back to top

    1. Is Verizon Wireless or the government tracking my location as part of the Wireless Emergency Alert system?

      No, your location information is not requested, provided or maintained in the delivery of a Wireless Emergency Alert (WEA). WEAs are broadcasted within counties or zones determined by Authorized Senders. All devices compatible with WEA that are located within a targeted zone will receive these alerts.

      Back to top

    1. I have the same, or similar, device as someone I know who received a Wireless Emergency Alert. Why didn’t I receive this alert?

      Devices are released containing differing revisions of software and firmware. Earlier devices of the same or similar model may not be capable of receiving the Wireless Emergency Alerts (WEAs). If your device is compatible with WEA, you will receive the alert. If not, your device will not receive them.

      Back to top

    1. What geographic locations will receive Wireless Emergency Alerts?

       

      Authorized Senders determine which locations will receive a specific alert based on the area defined by the geographical latitude and longitude of the emergency. As circumstances dictate, Authorized Senders will identify  targeted areas for each specific alert. Devices compatible with Wireless Emergency Alerts (WEAs) that are operating within the area targeted will receive the WEA. Those devices operating in areas not targeted by Authorized Senders will not receive the alert.

      Back to top

  1. If I’m on a call or in a data session when a Wireless Emergency Alert is released, will I receive the alert?

    No, if you are engaged in a voice or data session when alerts are released, you will not receive the alert.  Alerts may be re-broadcast at specific intervals in the targeted geographic locations, in order to reach as many devices as possible. However, after that interval has concluded, or the alerts have been superceded, the original alert will no longer be released..

one2many introduces LTE Cell Broadcast emergency alerts


one2many, the world’s leading Cell Broadcast company, has today announced that it has successfully completed IOT for its LTE interface. The addition of SBc to its library of network interfaces enables mobile operators to extend Cell Broadcast services, like Emergency Alerts, to their next generation LTE networks.

 

Over 300 operators have committed to LTE, and the GSA (Global mobile Suppliers Association) expects to have 150 commercial LTE networks operating in 64 countries by end-2012. As LTE handsets become available in the market place, one2many’s customers have requested LTE support on their multi RAN technology CBC platforms. Cell Broadcast, a one-to-many textual broadcast technology, is standardized and available on 2G, 3G and now LTE. In addition, CB is the only standardized wireless technology for Emergency Alerts.

 

Cell Broadcast is being introduced worldwide as a next generation wireless Emergency Alert service and will continue to play a crucial role in public safety, allowing governments to make vital public announcements to millions of citizens, within seconds, on a location-aware basis, without violating subscriber privacy or being affected by network congestion. Some of the Public Warning initiatives around the world are: EU-Alert, ETWS and Wireless Emergency Alerts (WEA – a part of CMAS) which was recently launched in the United States by the FCC and FEMA.

 

Maarten Mes, Managing Director of one2many, commented: “There is no better use of mobile technology than for Emergency Alerts. Our customers have requested and even demanded LTE support on our Cell Broadcast systems which are already in use on CDMA, GSM, 3G and Wifi networks. We are delighted to enable our customers to create a safer world for their subscribers.”

 

one2many provides Cell Broadcast technology to telecoms operators across the world.  Cell Broadcast technology delivers a non-intrusive, real-time service for the distribution of text-based messages to mobile handsets, specific to their current location. Cell Broadcast is capable of broadcasting one single message to reach all mobile handsets in an area as small as one radio cell and as big as an entire country. Sending a message to millions of handsets takes a matter of seconds, making the service ideal for applications such as public warning, location-based services and mobile social media.

Peace of mind for a tourist paradise


Peace of mind for a tourist paradise

The Maldives comprises around 300,000 people living in 200 islands among a total of around 1,200 small islands located in the Indian Ocean south of India.  The densely populated capital Malé is home to one-third of the population.  The atoll nation is the wealthiest in the region with a Gross Domestic Product (GDP) per capita of USD 2,992 and more mobile connections than people (Aug 2008).[1]

Ninety two of the uninhabited islands have been converted to resorts that attract high-end tourists, amounting to more than one-fifth of the country’s population during the winter peak.  Tourism is the most important industry, contributing around 27 per cent of the GDP.  According to the Asian Development Bank, the Maldives was among the worst affected by the 2004 Indian Ocean tsunami.  Loss of life was small, but around one-third of the population was affected and property damage was estimated to have been around 60 per cent of the GDP.[2]  Ensuring public safety and giving visitors a sense of security are thus high priorities for the Government.

The highly dispersed population (it takes 48 hours to go from one end of the Maldives to the other by boat) is one of the reasons why radio and television would be less than ideal for public warning.   Tourists are unlikely to listen to national channels.  In any case, radio and TV sets have to be switched on for warnings to be communicated.   Complete coverage of inhabited and resort islands, the near ubiquity of handsets among both citizens and guests and their ability to sound alerts pointed to mobiles as an attractive option.

Short message service (SMS) and cell broadcasts (CB) are two options for public warning via mobile.   The former is better known but is unsuited for public warning.

Short Message Service (SMS)

Cell Broadcast (CB)

Messages sent point-to-point (messages directed to handsets) Messages sent point-to-area (messages directed to radio cells)
Requires input of recipient phone numbers Does not require input or knowledge of numbers
Only pre-registered numbers notified All numbers within a cell notified
Messages cannot be differentiated by location of recipients Messages can be differentiated by cells or sets of cells
Subject to congestion and thereby, delay Being broadcasts, not subject to congestion
140-160 characters in length.  Can concatenate up to five messages 93 characters.  Can concatenate up to 15 ‘pages’ to produce a single message of up to 1200 bytes of data
No indication that message is generated by a legitimate authority Not possible for outsider to generate a cell broadcast so greater authenticity

A recent US Federal Communications Commission (FCC) Order on public warning via mobiles found SMS to be unsuitable and indicated that operators should instead use the point-to-multipoint capabilities of networks.   CB is the only viable method at the present time.  Since handsets incapable of delivering public warnings will have to carry notifications, this has turned the tide among manufacturers and operators in favour of CB.

The Telecommunications Authority of the Maldives (TAM) requested LIRNEasia, a regional telecom policy and regulation think tank with expertise in disaster early warning, to identify the preconditions necessary for the use of CB for early warning and to evaluate its potential for commercial applications.   The biggest barrier was found to be lack of knowledge.  In the tiny but intensely rivalrous Maldives industry, the operators, each with a customer base less than that of a small city elsewhere, focus almost exclusively on marketing.  However, upon being educated on the existence of over 66,000 logical CB channels, they have quickly realized CB’s potential not only for public warning but for myriad commercial and other applications.

Obviously, the efficacy of a public warning technology rests on the speed and accuracy of warnings and orders issued by Government on one side and the readiness to take appropriate action by the warned populace.  Tourist resorts are organized communities with structures for decision making and executing.   With periodic training and refreshing, they can be prepared to respond appropriately.  Ensuring general community preparedness poses a more difficult challenge.

CB is an intrinsic feature of GSM, UMTS and IS 95 CDMA networks, and is thus available in the two Maldivian networks.  But it must be activated.   Most handsets are capable of receiving CB messages but the feature must be turned on.  However, in the early stages, getting customers to turn on the feature could be an effective way of educating them of mobile-based public warning.

Following stakeholder meetings that included sharing of information on the ongoing CB channel-standardization work of Study Group 2 of the Telecommunication Bureau of the International Telecommunication Union (ITU-T) and experience in attempting to use CB for public warning in Sri Lanka, the recommendations to TAM are being finalized.   They include the constitution of a “trust protocol board” to develop the terms of access to the CB broker server to ensure security and the conduct of live demonstrations on a test channel that will not be seen by the public.  The latter is likely to bring up technical issues that require resolution before full-scale implementation.

Once technical implementation is complete, a public awareness campaign will be required to get citizens to switch on the CB function in their handsets.   It will take time and success in ITU-T standardization efforts for all tourists to automatically receive warning messages on their roaming mobiles.  A discreet campaign telling tourists how to turn on the Maldivian warning channel can not only enhance their security but also communicate the image of a caring Maldives.  For sustained adoption, it will be necessary for the regulator to continue discussions with the operators to develop a framework for commercial CB applications and to encourage such uses.

EU mobe warning system for imminent disasters won’t work on iPhone


Europe is shuffling towards an international agreement on emergency alerts delivered to our mobile phones, but if current plans continue you might not ever know you received one.

 

The idea is being discussed today at the European Emergency Number Association (EENA) with various industry and government reps in attendance, but once they agree they’ll likely be mandating an alert mechanism which won’t audibly alert half the population, and could leave iPhone users to the mercy of the encroaching zombie horde as their handsets don’t seem to get the message at all.

iOS 6 has some support for the Cell Broadcast mechanism the EU wants to make available to national emergency services, though it’s better at responding to the US WEA system messages which alerted residents of the impending arrival of Hurricane Sandy earlier this month. The US system only went live in May and only works on the more-recent handsets, but is already proving valuable.

 

Cell Broadcast should be a better mechanism – it’s part of the GSM standard though not implemented by every operator and not supported by every handset. The idea is that a GSM (or 3G) base station can send out a message to every handset attached to it, with the handsets deciding if they want to receive or ignore the message based on user preferences, but few handsets sound an audible alert even when a message is received, and support for the standard is far from universal.

 

Cell Broadcast was once envisioned as a mechanism for delivering cricket scores and other time-critical information which customers might be convinced to pay for, but these days it’s hardly used at all, as Vodafone explained to one customer who’d stumbled across the Cell Broadcast settings on a smartphone:

 

“The option of cell broadcasting is mainly used by network teams when investigating issues and will sometimes be used by emergency services” it said – though hopefully not in an emergency, given the lack of reach.

 

That’s not stopped the Netherlands adopting an emergency alert system based on Cell Broadcast, following trials in 2007 which showed messages reaching around 90 per cent of handsets (and in part motivated by the proliferation of “citizen journalism” which spreads scares and rumour faster than the government can address them, unless the government has access to such a mechanism).

 

The geographic nature of Cell Broadcast, and the fact that it is not susceptible to overloading, make it an attractive and elegant solution. But some, such as Intersec’s Gary Buchwald, argue that SMS can be equally robust, guarantees delivery and sounds an audible alert on every handset.

 

Intersec makes servers which add geographic targeting to SMS delivery, integrating with the operator’s Home Location Register (HLR), which knows the location of every customer all the time. With that data the company can deliver an SMS message to everyone within a specific region, without having to rely on partially supported standards. Cell Broadcast messages are less discerning, so will (for example) arrive on a handset of someone roaming in the area, but neither can it be adjusted to match the language of the recipient.

 

There’s also a question as to whether the SMS infrastructure could support such loading, though Intersec is adamant it could. China Mobile recently boasted it could deliver 25 million text messages, enough to cover the population of Beijing, in less than 10 seconds, which would seem to make Cell Broadcast entirely redundant.

 

Which is why the Americans have come up with something entirely new for their Wireless Emergency Alerts. Handset support for that system might be lacking now, but US replacement cycles mean messages reaching just about everyone by the end of 2014, and every handset comes with an interface allowing the user to ignore Amber Alerts (missing children) and Imminent Threat Alerts (most likely weather, but could be other disasters) though there’s no option to ignore Presidential Alerts should Obama decide to say “hi” to the whole country.

 

The EU will, most likely, go with Cell Broadcast and try to bully the handset manufacturers into better supporting the standard, though Buchwald reckons they’ll have to switch to SMS eventually. That’s unless they decide to embrace the US alternative, though EU citizens might not be keen to see their presidential decrees being unstoppable.

Cell broadcasting used to warn public about Sandy


With slow-moving Sandy leaving New York State, they are counting the dead. It appears that 22 people died. Each death is a tragedy that the disaster managers would have loved to avoid. But can you imagine what the toll would have been if not for extensive planning and early warning?

 

The word “cell broadcasting” is not used in the piece from the Atlantic that I am quoting below, but it is quite clear that she is talking about cell broadcasting, a topic we have researched and written about extensively. Now that its efficacy has been established, I hope the standardization work necessary to make it even more effective will gain some momentum.

 

See here for a short summary of the cell broadcasting work we did for the Communication Authority of the Maldives. This piece was included as a box entitled “Peace of mind for a tourist paradise” in World Disasters Report 2009: Focus on early warning, early action, pp. 29-30. Geneva: International Federation of Red Cross and Red Crescent Societies.

The importance of mobile phone access was on display last night in New York City, as cell phones became essential public safety communications devices. Some cell phone subscribers got emergency messages pushed directly to their phones. “Imminent Threat Alert,” read one that came in just after 9:30 p.m. “Go indoors immediately and remain inside. DO NOT DRIVE. Call 9-1-1 for emergencies only.” (Here’s a fuzzy photo of a friend’s phone.)

 

In those cases, New York City officials were making use of a federal program called PLAN, or the Personal Localized Alerting Network. PLAN grew out of the Warning, Alert and Response Network (WARN) Act that Congress passed in 2006, and it was — somewhat fortuitously, in retrospect — tested in New York City beginning last spring, six months ahead of the rest of the country

 

WARN was a bid to update the old Emergency Alert System of “This is a test…” fame. Americans are getting their information from a far more diverse array of sources than in years gone by, so WARN’s purpose was to upgrade the emergency alert system to reach them through a wider variety of channels. It was also an experiment in figuring out how to take the best stuff we know about technology and apply it to emergency response. The “L” in “PLAN,” “Localized,” referred to the fact that your cell phone will know if you happen to be in the five boroughs. At launch, Mayor Michael Bloomberg explained that “given the kinds of threats made against New York City at the World Trade Center, Times Square, and other places popular with visitors and tourists, we’ll be even safer when authorities can broadcast warnings to everyone in a geographic area, regardless of where they came from or bought their phone.”

Cell Broadcast Settings Menu Came With Jelly Bean for Verizon’s Galaxy Nexus


Screenshot_2012-08-30-13-09-40

After digging into settings menus in the Jelly Bean update that was released this week for Verizon’s Galaxy Nexus, a handful of readers noticed that a new “Cell Broadcast settings” area was now included. This new area appears to give you control over emergency alerts that could push through to your handset. For example, a child abduction notification could appear on your phone should one happen near you. I’m assuming that a notification of some sort would also pop up if say a hurricane were blowing through, if an earthquake just went down, or if some sort of terrorist activity that threaten lives was happening. You can even set your phone up to speak them out loud as they appear on your device.

 

We hadn’t noticed these on any other phone before, even a GSM Galaxy Nexus running Jelly Bean, and wanted to share. We aren’t sure if this is something that is only showing because this is a test build or if this is indeed going to be a new standard in Android going forward. Pretty neat, though, right?

 

To access the menu, head into Settings>Wireless & networks>Cell broadcasts.

 

Cheers Steven and 4n1m4l!
