Network Event Prediction for Wireless Application Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in predicting and managing network events such as handovers, which can impact the Quality of Service (QoS) for applications like V2X, leading to potential misbehavior of applications and reduced accuracy in key performance indicator (KPI) estimation.
Innovation Solution
The system predicts upcoming network events affecting user equipment (UEs) and notifies application servers, providing detailed information about expected events to enhance application awareness and adaptation, thereby improving the predictability of application performance.

Engineering Contradiction Analysis
1Reliability
If the application is not aware of upcoming network events, then the application can operate without additional complexity, but the application may misbehave during network events and KPI estimation accuracy deteriorates
Solution Approach 1:
The network predicts upcoming network events (handovers, connectivity loss) in advance and notifies the application before they occur. This allows the application to prepare adaptive responses beforehand, ensuring reliable behavior during network events without requiring complex real-time detection mechanisms in the application itself.
Solution Approach 2:
The network acts as an intermediary by predicting events and notifying the application server. This mediator approach provides the application with network event information without requiring the application to implement complex prediction algorithms, thus improving reliability while keeping application complexity low.
2Measurement precision
If ad hoc algorithms are designed to estimate specific network events, then prediction accuracy improves, but system complexity increases
Solution Approach 1:
The network performs self-service by implementing its own event prediction and notification mechanisms. Rather than requiring multiple ad hoc algorithms in different components, the network centrally predicts events and provides information to applications, achieving high accuracy while avoiding the complexity of distributed prediction algorithms.
3Speed
If the application reacts to connectivity interruption without awareness of expected events, then the application can respond quickly, but the application may incorrectly switch to safe mode and reduce productivity
Solution Approach 1:
The application receives advance notification of expected connectivity interruptions and prepares appropriate responses beforehand. When the interruption occurs, the application recognizes it as an expected event and maintains service continuity rather than incorrectly switching to safe mode, thus preserving productivity while responding quickly.

AI summary
In one aspect, network nodes may be configured for improving predictability of application performance in a wireless communication system. A mobile network domain predicts an upcoming network event affecting a UE operating in the wireless communication system and notifies an application server (AS) providing an application service to the UE of the predicted network event. The AS may be notified through an Application Function (AF). The AS receives the notification and adjusts operation of the application service and/or a configuration of the UE, in response to the notification.
