Public Warning System

Geo-targeted, real-time and context aware alerts
to a population at risk


Large-scale natural and human-made disasters frequently put the lives and property of citizens at risk. However, many existing public warning systems (PWS) are not equipped to provide at-risk populations with the targeted, real-time alerts they need to ensure their safety. These systems are also not sufficient to meet current PWS regulatory requirements in many countries.

The Nokia Public Warning System solution provides the full end-to-end set of capabilities that governments and mobile network operators (MNOs) need to implement PWS services and meet PWS regulatory requirements. The solution includes:

  • An alert management portal and an alert gateway which enable governments to rapidly create, manage and geo-target alert messages.
  • A cell broadcast service-based (CBS) solution that enables MNOs to broadcast context-aware alert messages and warnings to mobile devices in a specific geographic area.
  • A location-based SMS (LB-SMS) solution that augments CBS technology with SMS communications and improved situational awareness for emergency authorities.
  • A package of integration services that enable governments and MNOs to define, design, deploy and test the solution across their networks with all stakeholders involved.

Use cases

The Public Warning System solution supports a range of use cases that give public safety agencies and MNOs the communications speed, reliability, and control they need to provide timely and accurate alerts when an emergency occurs.
