u.warn CBC

Real-time and location-based alerts without the need for cell service or internet network during natural disasters or national emergencies.

Communicate to millions in seconds!

Our u.warn Cell Broadcast Center system (u.warn CBC) is the fastest and most cost-effective way to deliver mass messaging to mobile phone users. Celltick by Utimaco the global leader of mass mobile communication developed u.warn CBC according to 3GPP/ATIS standards. The system has been used successfully for two decades and deployed in four continents. u.warn CBC allows simultaneous delivery of text messages in real time, to millions of mobile users within a specified geographical area. u.warn CBC mass messaging reach achieves this without requiring extra network bandwidth.

Key Benefits


Real-time and location-based alerts

With CBC’s “Write once, publish to all” technology, real-time location-based alerts are broadcast and delivered within seconds, whilst providing the highest caliber of cell site resolution.


Compatible with all ran vendors

u.warn CBC connects to all RAN (Radio Access Networks) vendors including Ericsson, Nokia, Huawei, ZTE, Siemens, Motorola and other established vendors. It is our obligation to keep up with any changes in the protocols made by the RAN vendors assuring continuous operation of the system, verifying every message reaches its destination.


Complies with all emergency standards

Our CBC is fully compliant with international emergency related standards and protocols including CMAS, EU-Alert and CAP. On offer as well national implementations of an emergency protocol and support its implementation with mobile phone vendors.


Operates when networks are jammed

In emergency situations, it’s human nature to try contact everyone by calling or texting. These actions may heavily congest networks during these crucial times and cause systems to crash. u.warn CBC connects directly to the RAN, so it’s not at all affected. Furthermore, the CBC does not require a data connection and works on both smartphones and feature phones, ensuring that EVERYONE IS REACHED.


Compatible with all types of networks

u.warn CBC is congruent with all types of networks – 5G, 4G, 3G, 2G. The system can be used on top of other existing CBC to support newer types of networks.


All levels of redundancy

u.warn CBC also supports all kinds of redundancy levels including LHA (Local High Availability) and geo redundancy. It can be deployed over bare metal or on a cloud/VM. u.warn CBC can be implemented either in centralized or distributed topologies.



Distributed and centralized topology

For governments that are looking for an integrated public warning system, we offer a national central system with a single CBC that connects to all the mobile operators in the country. The system aggregates alerts from a variety of authorities and sensors that are spread across the country and manages the dissemination of these alerts, over a single CBC that allows also SMS delivery, to the required geographical areas. To protect the various mobile operators information, the central CBC is equipped with a virtual CBC feature (vCBC) that allows separate and private environments for each of the mobile operators.

Decentralized situations are fully supported by the u.warn CBC, also. In such deployment scenarios the CBC can be integrated at each mobile operator separately. If required, the u.warn CBC can coexist with other CBCs at the same network operator, for example, just to support new mobile network technologies, like a 5G core.

Robust and field proven

u.warn CBC, developed according to GSM/UMTS/LTE standards, has been in use for almost two decades, and has been deployed by more than 70 mobile operators across five continents, for both emergency alerting and commercial purposes. Integration with 5G core networks took place recently. Our customers include some of the world’s largest mobile operators with thousands of RAN controllers that are spread across multiple time zones.
