Public Warning System

Public Warning System (PWS) in cellular networks is a cell broadcast-based system specified in Third Generation Partnership Project (3GPP) and standardized by multiple Standards Development Organizations (SDOs) throughout Europe, Asia, and the Americas. Cell broadcast-based PWS provides wireless emergency alerts to the public in an affected area without the need for subscription or determining the device’s location. In addition, it provides alerts to the public with a given country as well as support the receipt of alerts for users who are roaming internationally.

MARCOM (Maritime Communication Services over 5G systems)

The first 3GPP Technical Specification covering service requirements (Stage 1) for the support of maritime communication (MARCOM) over 3GPP systems (TS 22.119). The document aims to support the maritime communication services between users ashore and at sea or between vessels at sea over 3GPP system that are targeted to improve maritime safety, protect the maritime environment and promote the efficiency of shipping by reducing maritime casualty caused by human error, in particular, involving small ships and fishing vessels. In addition, the outcome of the technical report is expected to narrow the information gap between mobile users on land and shipboard users on vessels at sea by making it possible to provide the mobile broadband services.
