Emergency Message Delivery via Network Side Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face delays in transmitting emergency messages, which is critical for timely emergency services like accident warnings in intelligent transport systems, as they require seconds for message transmission whereas emergency services demand sub-millisecond response.
Innovation Solution
A method where a network side device receives an emergency message from a UE within a preset group, identifies it using a message identifier, and directly delivers it to other UEs in the group, bypassing the need for upload to a Core Network and management center, utilizing channels like RACH, FACH, and RRC layers for efficient transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the current transmission process (uploading to CN and management center) is used, then the system can handle normal message transmission, but the transmission delay exceeds the emergency service requirement
Solution Approach 1:
The patent extracts the emergency message transmission path from the conventional CN and management center routing. By identifying emergency messages through message identifiers and establishing a direct delivery mechanism from network side device to UE, the system removes unnecessary intermediate steps (CN upload, management center processing) that cause delay, while maintaining security and reliability through direct network-controlled delivery
Solution Approach 2:
The system performs preliminary identification of emergency messages at the network side device using message identifiers before transmission. This preliminary classification allows the network to prepare and prioritize emergency message delivery paths in advance, ensuring that when emergency messages occur, they can be routed directly without waiting for conventional processing cycles
2Speed
If UMTS is used for emergency message reporting, then seamless coverage and convenient layout are achieved, but the transmission speed is too slow for emergency services
Solution Approach 1:
The patent implements dynamic message routing based on message type. The network side device dynamically determines the transmission path based on whether a message is identified as emergency-related through its identifier. This dynamic adjustment allows the system to switch from conventional slow UMTS processing to accelerated direct delivery paths specifically for emergency messages, while maintaining normal UMTS operation for other traffic

AI summary
A method for transmitting a message, a UE and a network side device are disclosed. The method includes: receiving, by a network side device, a message reported by a first user equipment UE, where the first UE is a UE in a preset UE group; identifying the message, reported by the first UE, as an emergency message when the message carries a message identifier of the emergency message; and delivering the emergency message to another UE except the first UE in the preset UE group. After identifying a reported emergency message, a network side may immediately deliver the emergency message to each UE. Because the emergency message does not need to be uploaded to a CN and a server of a management center through the network side for delivering, a transmission delay of the emergency message is reduced, which improves a speed that the UE obtains the emergency message.
