5G Broadcast Infrastructure for Public Warning Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public warning systems fail to effectively inform the public about the nature of impending dangers, leading to inadequate reactions, as they rely on sirens and lights without providing clear information, and are unreliable during catastrophic events when internet services are disrupted.
Innovation Solution
A 5G or LTE-based public warning system that broadcasts content to all users in a coverage area, using a content provider entity, broadcast core entity, and management entity to generate and adapt messages with links to additional information, ensuring that users can access critical details without relying on mobile networks, and includes a redundant infrastructure for reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sirens and warning lights are used to alert the public, then the public becomes aware of danger, but the public does not know what particular kind of danger is to be expected or how to react correctly
Solution Approach 1:
The patent combines traditional alarm signals (sirens and warning lights) with modern digital communication technologies (5G/LTE broadcast infrastructure) to create an integrated warning system. This merging allows the system to deliver both alert signals and detailed information about danger type and appropriate reactions through multiple channels simultaneously, resolving the contradiction between raising awareness and providing actionable information.
Solution Approach 2:
The patent introduces an intermediary information delivery mechanism that bridges the gap between simple alarm signals and complex information about danger types and reactions. This intermediary system processes and distributes targeted information through broadcast infrastructure to specific user groups based on their location and risk profile, ensuring people receive both the alert and the knowledge of how to respond appropriately.
2Loss of information
If regular internet services are used to provide additional information, then subscribers can obtain information via smartphone applications, but internet access cannot be guaranteed in case of catastrophic situations
Solution Approach 1:
The patent implements prior cushioning by establishing a redundant broadcast infrastructure (5G/LTE) that is specifically designed to remain operational during catastrophic events when regular internet services fail. This backup communication channel is prepared in advance and can deliver critical information about danger types and reactions even when mobile networks and internet services are disrupted, ensuring continuous information delivery capability.
3Reliability
If a 5G or LTE-based broadcast infrastructure is used to broadcast content to all users, then effective communication of danger information is achieved during network outages, but system complexity increases
Solution Approach 1:
The patent leverages the universality of existing 5G/LTE broadcast infrastructure, which is designed to serve multiple purposes including public warning, emergency communication, and general mobile connectivity. By utilizing this multi-functional infrastructure rather than building a dedicated simple system, the patent achieves reliable communication during outages while avoiding the complexity of designing and implementing a completely new specialized system from scratch.

AI summary
A public warning system for broadcasting content comprises a 5G-based or LTE-based broadcast infrastructure (18) configured to broadcast content to all users in a coverage area of the broadcast infrastructure (18). The public warning system (10) comprises a content provider entity (14) configured to provide content. The public warning system (10) comprises a broadcast core entity (16) that is configured to process the content provided by the content provider entity (14). The public warning system (10) comprises a management entity (22) configured to assign the content to at least one user service, thereby generating a message to be broadcasted. The public warning system (10) comprises an operator interface (24) via which access to the management entity (22) is enabled to adapt the message. Further, a method of broadcasting content is described.
