UE Throughput-Based Handover Triggering in Cellular Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication networks, particularly those following the LTE architecture, fail to consider actual data throughput when triggering handovers, leading to inadequate user experience during high-demand events due to limited data bandwidth and resource distribution among base stations.
Innovation Solution
A system where user equipment (UE) processor circuitry monitors data throughput, identifies low throughput levels, and triggers a handover by sending a manipulated handover request message to transfer from one base station to another with better data throughput, ensuring improved data bandwidth and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If handover decision is based on measured RSRP quantities, then UE battery consumption is reduced and signal strength broadcasting is lowered, but actual data throughput is not improved during high-demand events
Solution Approach 1:
The patent changes the handover triggering parameter from RSRP (signal strength) to data throughput. The UE monitors actual data throughput and triggers handover when throughput falls below a threshold, directly addressing the limitation that RSRP-based handover does not guarantee actual data performance during high-demand events.
2Productivity
If handover is triggered based on RSRP thresholds, then handover decisions are simple and fast, but data bandwidth distribution is not optimized during local events
Solution Approach 1:
The patent implements a feedback mechanism where the UE continuously monitors data throughput and uses this feedback to trigger handover decisions. The system establishes a throughput threshold and compares actual throughput against this threshold, creating a closed-loop control system that optimizes data bandwidth distribution based on actual performance rather than just signal strength.
3Reliability
If the system monitors actual data throughput, then handover decisions improve user experience, but the complexity of monitoring and decision-making increases
Solution Approach 1:
The patent enables the UE to autonomously monitor its own data throughput and make handover decisions based on predefined thresholds. The system uses self-service by having the UE independently assess its data performance and trigger handover without requiring complex network-side intervention or additional infrastructure, thereby improving reliability while keeping implementation practical.

AI summary
A system and method for triggering a handover in cellular networks based on throughput of data in a User Equipment (UE). The UE manipulates at least one measured quantity that affects a decision of a base station to trigger the Handover of the UE to a neighboring Base Station, and send a handover request message that include the manipulated measured quantity.
