UE Mobility Parameter Reporting for Reliable Handover Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handover procedures in wireless communication networks suffer from mobility failures due to suboptimal tuning of mobility parameters, as UEs adjust these parameters without reporting to the network, leading to resource consumption and service interruptions.
Innovation Solution
Implement a reporting mechanism for UE-adjusted mobility parameters, allowing UEs to adjust mobility parameters within specified ranges and conditions, and transmit information about these adjustments to the network node, facilitating optimized parameter tuning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UEs adjust mobility parameters autonomously without reporting, then parameter adaptation speed is improved, but mobility reliability deteriorates due to suboptimal tuning
Solution Approach 1:
The patent implements a feedback mechanism where UEs report adjusted mobility parameters to the network node. The network node receives these reports and uses the information to further optimize parameter tuning. This feedback loop resolves the contradiction by maintaining fast local adaptation while ensuring overall reliability through network supervision and coordinated optimization.
2Adaptability or versatility
If UEs adjust mobility parameters without network coordination, then device autonomy is improved, but resource consumption increases due to mobility failures
Solution Approach 1:
The patent enables UEs to autonomously adjust mobility parameters based on local conditions and report only the adjusted values to the network. This self-service approach maintains device autonomy while reducing resource consumption by avoiding unnecessary network interventions and preventing mobility failures through intelligent local decision-making combined with selective reporting.
3Device complexity
If UEs adjust mobility parameters without reporting, then signaling overhead is reduced, but handover performance deteriorates
Solution Approach 1:
The patent extracts only the essential information (adjusted mobility parameter values) from the UE's local adjustments and reports only this critical data to the network node. This selective reporting approach minimizes signaling overhead while providing the network with sufficient information to maintain or improve handover performance through coordinated optimization.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a configuration allowing an adjustment within a range to a configured value associated with a mobility parameter and indicating one or more conditions associated with the adjustment to the configured value. The UE may adjust the configured value associated with the mobility parameter in accordance with the one or more conditions being satisfied. The UE may transmit, to the network node, information related to adjusting the configured value associated with the mobility parameter. In some aspects, the transmitted information indicates one or more of an adjusted value associated with the mobility parameter or a reason for adjusting the configured value associated with the mobility parameter. Numerous other aspects are described.
