True Corporation provided full support until the system became operational. CBS is now one of the core channels within the T-Alert framework.<br \/>\nTo strengthen multi-channel communication, True is preparing to test alerts through True ID for online TV audiences, expanding access and coverage for the public.<\/p>\n<p><strong>How the Cell Broadcast System Works<\/strong><\/p>\n<p>The CBS system requires two main components:<\/p>\n<ul>\n<li><strong>CBE (Cell Broadcast Entity)<\/strong> \u2013 operated by government agencies, with DDPM authorized to send messages in the event of disasters or emergencies.<\/li>\n<li><strong>CBC (Cell Broadcast Center)<\/strong> \u2013 operated by mobile service providers. True Corporation has fully installed CBC nationwide, achieving 100% readiness and active operation.<\/li>\n<\/ul>\n<p><strong>Mr. Narupon Rattanasamaharn, Head of Regulatory &amp; Government Relations Division at True Corporation Plc., <\/strong>said, \u201cCell Broadcast alerts, implemented in partnership with DDPM and the NBTC, are sent only during severe emergencies, such as natural disasters, violent incidents, and other threats that put lives and property at risk. This fast and precise communication enables people to prepare and follow safety instructions without delay.\u201d<\/p>\n<p>The Cell Broadcast System (CBS) can define alert areas ranging from very localized zones to provincial, regional, or even nationwide coverage, without requiring users to install additional applications. This makes CBS more effective than traditional SMS, allowing warnings to reach people in at-risk areas with greater speed and accuracy.<\/p>\n<p>At present, the Department of Disaster Prevention and Mitigation (DDPM) and related agencies have established Standard Operating Procedures (SOP) for transmitting emergency alerts through CBS, as well as Common Alerting Protocol (CAP) message standards. These currently cover eight types of hazards: earthquakes, tsunamis, storms, floods, landslides, cold spells, PM 2.5 air pollution, and violent incidents in public areas. Work is also underway to expand coverage to six additional hazard types, including pandemics, fires and hazardous chemical incidents, threats from external armed forces, traffic and transport emergencies, cyber threats, and other hazards, which are expected to be completed by the end of 2026.<\/p>\n<p><strong> <img decoding=\"async\" class=\"alignnone size-full wp-image-27356\" src=\"https:\/\/trueblog.info\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001.jpg\" alt=\"\" width=\"2500\" height=\"1667\" srcset=\"https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001.jpg 2500w, https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001-300x200.jpg 300w, https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001-1024x683.jpg 1024w, https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001-768x512.jpg 768w, https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001-1536x1024.jpg 1536w, https:\/\/www.true.th\/blog\/wp-content\/uploads\/2025\/09\/TRUE_CBS001-2048x1366.jpg 2048w\" sizes=\"(max-width: 2500px) 100vw, 2500px\" \/><\/strong><\/p>\n<p><strong>Photo Caption<\/strong> <strong>:<\/strong> <strong>Mr. Ansit Sampantarat <\/strong>(sixth from left), Permanent Secretary of the Ministry of Interior, and <strong>Mr. Chettha Mosikarat <\/strong>(fifth from left), Director-General of the Department of Disaster Prevention and Mitigation (DDPM), visited the True Corporation booth at the \u201cT-Alert\u201d seminar and public communication event.
