Network Node Non-Radio Degradation Event Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks inefficiently handle notifications for non-radio degradation events, as all user equipment (UE) in a cell are notified, wasting resources and disturbing users not affected by the event, with no efficient solution for idle mode UEs.
Innovation Solution
A network node detects non-radio degradation events, stores information about the event, and transmits an indication, allowing only UEs within a pre-determined distance to retrieve and notify users, thereby reducing unnecessary notifications and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all user equipment (UE) in a cell are notified of non-radio degradation events, then complete information coverage is achieved, but system resources are wasted and users not affected are disturbed
Solution Approach 1:
The patent applies local quality by differentiating notification delivery based on UE location relative to the event. Instead of uniform notification to all UEs, the system provides targeted notifications only to UEs within a pre-determined distance from the event location, making the notification quality local rather than universal.
Solution Approach 2:
The patent segments the cell area into zones based on distance from the event location. UEs are divided into two groups: those within the pre-determined distance who receive notifications, and those outside who do not. This segmentation allows selective information delivery that reduces resource consumption while maintaining necessary coverage.
2Loss of information
If all user equipment (UE) in a cell are notified of non-radio degradation events, then complete information coverage is achieved, but users not affected are disturbed
Solution Approach 1:
The system implements local quality by tailoring the notification delivery to the specific location of each UE. Only UEs located within the pre-determined distance from the event receive notifications, ensuring that information is provided locally where it is relevant while avoiding disturbance to users in other areas.
Solution Approach 2:
The cell is segmented into an affected zone (within pre-determined distance) and an unaffected zone. This segmentation allows the system to deliver notifications selectively to the affected segment while leaving the unaffected segment undisturbed, thereby reducing harmful factors.
3Loss of information
If notifications are transmitted to all UEs, then no information is lost, but communication efficiency decreases due to unnecessary alerts
Solution Approach 1:
The notification process is segmented into targeted delivery to specific UEs based on their location. By dividing UEs into those who need notifications and those who don't, the system eliminates unnecessary communication overhead and improves overall communication efficiency while maintaining complete information delivery to the relevant subset.
Solution Approach 2:
The system applies partial action by transmitting notifications only to the extent necessary - specifically to UEs within the pre-determined distance. This partial notification approach avoids the excessive action of notifying all UEs, thereby improving communication efficiency without compromising necessary information delivery.
4Loss of information
If UEs continuously check for event information, then information availability is ensured, but power consumption increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing the list of UEs within the pre-determined distance from the event location. When an event occurs, notifications are immediately delivered to the pre-identified relevant UEs without requiring them to continuously check or calculate their relevance, thus ensuring information availability while minimizing power consumption.
Solution Approach 2:
The network performs self-service by automatically identifying and notifying the appropriate UEs based on their stored location information and the event location. UEs do not need to actively query or determine their relevance to events, as the system autonomously manages the notification process, reducing the energy burden on mobile devices.

AI summary
A method performed by a network node for enabling notifications to User Equipment users. The network node detects that an event associated with a non-radio degradation has occurred in a radio coverage area served by the network node. The network node then stores information about the detected event in a server, wherein the information comprises at least a location of the event. The network node then transmits an indication of the event, wherein the indication indicates that said information is available in the server.
