Emergency Multimedia Distribution Bearer for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency alert systems, such as cell broadcast, are limited by short text message restrictions, network congestion, and require manual activation on mobile devices, leading to incomplete and delayed information dissemination during emergency events.
Innovation Solution
A method utilizing an emergency multimedia capable distribution bearer with a priority indicator to deliver multimedia emergency services directly to multiple mobile terminals, ensuring prioritization and automatic activation, thereby overcoming limitations of traditional systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cell broadcast system is used to alert citizens via SMS, then mobile users can be informed of emergency events, but the information content is limited to short text messages with max 160 characters causing time delays and misinterpretation
Solution Approach 1:
The patent changes the parameter of message format from short text (SMS) to multimedia format, allowing comprehensive emergency information to be transmitted without character limitations. This enables detailed instructions, maps, and safety information to be delivered completely and accurately, resolving the contradiction between information completeness and delivery time.
2Reliability
If cell broadcast messages are sent via mobile network, then emergency information can be delivered to mobile phones, but the system is susceptible to network congestion causing delayed or undelivered messages
Solution Approach 1:
The patent introduces a dedicated emergency information transmission mechanism that acts as an intermediary between the emergency alert system and mobile users. This specialized channel bypasses the congested general mobile network, ensuring reliable and speedy delivery of emergency information even when the network is under heavy load.
3Ease of operation
If cell broadcast reception setting is required on each mobile phone, then messages can be received via cell broadcast service, but users are often not aware of this feature and do not manually activate it reducing system security
Solution Approach 1:
The patent implements a system where the mobile phone automatically receives and processes emergency information without requiring user activation or configuration. The emergency information transmission mechanism enables the device to self-activate the reception function, eliminating the need for manual user action while ensuring reliable delivery of emergency alerts.

AI summary
A method, devices, a system, and computer programs for informing multiple mobile terminals (UE10-90) of an emergency event are disclosed. The method comprises the steps of receiving (S300) emergency information associated with the emergency event, establishing (S400) an emergency multimedia capable distribution bearer for a delivery of an emergency service associated with the received emergency information, the emergency multimedia capable distribution bearer being associated with an emergency priority indicator indicating a higher priority for the emergency multimedia capable distribution bearer compared to further communication being not associated with the emergency priority indicator, and delivering (S600) the emergency service via the emergency multimedia capable distribution bearer to the multiple mobile terminals (UE10-90).
