This 5G Americas white paper discusses PWS and other alert systems in the Americas. Many countries in the Americas have deployed and are in the process of enhancing PWS.

Paging configuration in 5G is defined within SIB1, providing details about how UEs monitor paging messages to maintain energy efficiency while ensuring responsiveness to network events. The paging process is designed around the Paging Control Channel (PCCH), which serves as the communication medium for delivering paging messages.

Dec 17, 2021 · 3GPP has introduced CMAS and ETWS as Public Warning System (PWS) services using cell broadcast capabilities to effectively provide text based alerts and warnings to the public via a broadcast message sent to an alerting area defined by cell site coverage.

In this work, we conduct the first comprehensive investigation of PWS security in 5G networks. We demonstrate five practical atacks that may impact the security of 5G-based Commercial Mobile Alert System (CMAS) as well as Earthquake and Tsunami Warning System (ETWS) alerts.

The introduction of 5G technology provides enormous benefits to mobile applications including significantly higher capacity by tenfold from 4G’s and up to 100 times 4G’s speed. 5G provides low delivery latency, with much higher density of devices serviceable per geographical area.

In 5G, Public Warning System (PWS) is a critical component designed to disseminate emergency alerts and public safety notifications efficiently. PWS plays a crucial role in providing timely and widespread information to the public during emergencies, natural disasters, or …

This 5G Americas white paper discusses PWS and other alert systems in the Americas. Many countries in the Americas have deployed and are in the process of enhancing PWS. Industry participants in the U.S. and Canada have developed standards and have collaborated with 3GPP in developing standardized functionality for PWS.

Jul 24, 2018 · The paper by 5G Americas confirms that it is more beneficial for the general public to use cell broadcast-based PWS as opposed to point-to-point alerting methods such as Short Message Service (SMS) and Over-the-Top (OTT) applications to …

Jul 6, 2022 · In this work, we conduct the first comprehensive investigation of PWS security in 5G networks. We demonstrate five practical attacks that may impact the security of 5G-based Commercial Mobile Alert System (CMAS) as well as Earthquake and …

Dec 5, 2022 · PWS attacks disseminating fake warnings or concealing precarious events can have a serious impact, causing fraud, panic, physical harm, or unrest to users within an affected area. In this work, we conduct the first comprehensive investigation …
