MassAlert - public warning and informing system 

Emergency communication takes an important role in time of disaster. Effective risk management is not possible without an efficient way to warn and inform population about the dangerous situation and actions that should be taken to avoid or minimize the consequences.

It is especially important nowadays, when industrial and natural hazards make huge damage. National economies lose millions dollars every year – only in Europe disasters made more than 12 billion dollars damage in period 2001-2010 (

The sirens, TV, radio and other means of communication cannot guarantee tolerable results, as it is either not enough informative either hardly accessible in time of crisis. Also important that such means cannot inform about minor accidents, such as increased solar activity or wind chill factor. There were a lot of projects and activities in order to find effective way to inform population, such as European Union projects “Chorist” and "EU-Alert". The main goal was to find a conventional technology that could meet majority of the requirements for emergency communications. CellBroadcast technology was selected as one of the solutions that could effectively supplement existing warning systems:

  • uses existing technology;

  • mobile technologies have highest penetration;

  • enables to send informative warning messages to all population in few seconds;

  • does not create overload and isn’t affected by network congestions.

NTService® presents MassAlert™ system which utilizes newest technologies and enables government efficiently communicate with population in time of crisis. Solution is based on messaging via cellular networks using CellBroadcast technology. MassAlert™  also includes additional warning technologies:
  • IP alert solution, which enables to transfer emergency messages to personal computers, handheld devices and smart phones using WEB services;

  • digital TV alert solution, which enables to insert emergency messages to DVB-T/C stream;

  • siren control over CellBroadcast, IP and TETRA networks.

MassAlert™ key features:

Geografiškai orientuotų žinučių siuntimas – žinutės priklausomai nuo poreikio, gali būti siunčiamos visai šaliai, atskiriems rajonams, atskiroms savivaldybėms ar specialiai pasirinktoms poveikio zonoms;

  • Territory based broadcasting - ability to send alert messages to all country, regions, municipalities or selected zone.

  • Integrated Geographical Information Subsystem (Esri® ArcGis™);

  • Predefined messages for possible emergency situations and dangerous objects;

  • Secure access solutions for interconnection between system users and operators;

  • Hierarchical user right management and distributed architecture allowing multiple authorities to utilize system features depending on administrative division and responsibilities;

  • Distributed system control option allowing operations from multiple authorities;

  • Proven interoperability with many mobile network vendors (Nokia, Siemens, NSN, Huawei, Motorola, Ericsson, etc..);

  • High availability redundant architecture.

  • Complies to EU-ALERT and CMAS requirements for emergency communications.

System Architecture

System supports distributed architecture. It enables to utilize systems functionality in different authorities (fire and rescue department, police, military). User rights are assigned basing on territorial division and responsibilities.
