Towards a better Public Warning System (ePWS)

April 11, 2018

By Hyounhee Koo (SyncTechno), ePWS rapporteur

Additional requirements for an enhanced Public Warning System (ePWS) have been agreed at the recent 3GPP TSG SA#79 meeting, as an update to Technical Specification (TS) 22.268.

3GPP Public Warning Systems were first specified in Release 8, allowing for direct warnings to be sent to mobile users on conventional User Equipment (PWS-UE), capable of displaying a text-based and language-dependent Warning Notification.

Since that time, there has been a growth in the number of mobile devices with little or no user interface - including wrist bands, sensors and cameras – many of which are not able to display Warning Notifications. The recent growth in the number of IoT devices - not used by human users – also highlights the need for an alternative to text based Warning Notifications. If those devices can be made aware of the type of incident (e.g. a fire or flood) in some other way than with a text message, then they may take preventive actions (e.g. lift go to ground floor automatically).

Launch of the 3GPP CVD process

April 18, 2018

Under the guidance of our security group (SA3) and partner organization’s experts, we are able to announce that the 3GPP Coordinated Vulnerability Disclosure (CVD) process is now up-and-running.

The CVD will allow suspected or proven vulnerability caused by errors, omissions or ambiguities in our Technical Specifications to be reported and quickly forwarded to the appropriate 3GPP Group, to analyse and resolve the problem.

This is the first time that we have put a process in place for this activity, formalizing how individuals or organizations can provide information on vulnerabilities related to our deliverables.
