UE Data Stall Detection with Conditional Reselection Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to effectively detect and mitigate interference and congested networks, which are multiple-access networks capable of supporting multiple users by sharing the available network resources, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources.
Innovation Solution
A UE includes a processing system with an application processor configured to receive an indication of a data stall from a modem and initiate operations for data stall detection and mitigation, such as releasing a data interface, reestablishing it, performing a radio resource control reset, or initiating a subsystem restart, based on whether the stall is related to the modem or the application processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network reselection is performed to mitigate data stalls, then network performance may be improved, but unnecessary reselections occur when the stall is UE-related, wasting time and resources
Solution Approach 1:
The system implements feedback by monitoring data transmission status between the modem and application processor, detecting data stalls, and determining their origin (network-related or UE-related). This feedback mechanism enables conditional network reselection only when network issues are detected, avoiding unnecessary reselections for UE-related stalls and reducing latency while maintaining communication reliability.
2Reliability
If data stall detection and mitigation procedures are implemented, then communication reliability is improved, but system complexity increases due to additional processing operations
Solution Approach 1:
The application processor performs self-service by autonomously monitoring data transmission status, detecting data stalls, determining their origin through analysis of data availability and transmission patterns, and initiating appropriate mitigation procedures. This self-service approach improves communication reliability while minimizing additional system complexity by utilizing existing processor capabilities rather than adding dedicated detection hardware.

AI summary
In some aspects, an apparatus for wireless communication by a user equipment (UE) includes a processing system including one or more processors and one or more memories coupled to the one or more processors. The one or more processors include an application processor of the UE. The processing system is configured to receive, at the application processor from a modem of the UE, an indication of a data stall associated with the UE. The processing system is further configured to initiate, in accordance with the indication of the data stall, one or more operations associated with a data stall detection and mitigation procedure.
