UE Throughput Evaluation for WLAN Offloading Resource Pre-configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, the target serving cell cannot accurately determine the WLAN-side data flow offloading state and transmission experience of UE during handover processes, leading to inefficient resource allocation and potential service disruptions.
Innovation Solution
User Equipment (UE) evaluates the throughput ratio and change trend of data transmission between WLAN Access Points and source serving cells, reporting these results to the source control entity, which then determines resource pre-configuration policies for the target control entity, enabling more accurate resource allocation and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the target serving cell performs resource allocation without knowing the WLAN-side data flow offloading state, then the handover process can proceed quickly, but resource allocation efficiency deteriorates and service disruptions may occur
Solution Approach 1:
The source serving cell performs preliminary actions by evaluating the WLAN-side data flow offloading state and transmission experience before handover, then reports this information to the target serving cell. This allows the target cell to pre-configure resources appropriately before the UE actually handovers, resolving the contradiction between fast handover and efficient resource allocation.
2Reliability
If the target serving cell allocates additional resources by default assuming WLAN offloading, then resource pre-configuration can be performed, but resource waste increases when offloading is not actually occurring
Solution Approach 1:
The source serving cell provides feedback information about the actual WLAN-side data flow offloading state and transmission experience to the target serving cell. This feedback mechanism allows the target cell to accurately determine whether resource pre-configuration is necessary, avoiding both resource waste and insufficient allocation.
3Measurement precision
If the UE reports detailed throughput evaluation information, then the target serving cell can make accurate resource allocation decisions, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential evaluation results (throughput ratio and change trend) from the detailed throughput measurements, reporting only the necessary information to the source serving cell. This extraction principle reduces signaling overhead while maintaining sufficient accuracy for resource allocation decisions.

AI summary
The present invention disclosed an evaluation result reporting method and an evaluation result acquisition method, device and system. Herein, the evaluation result reporting method includes: UE performing an evaluation on a relation between throughputs of data transmission at a WLAN AP and a source serving cell (S402); and the UE reporting an evaluation result (S404). The present invention solves the problem that a WLAN-side data flow offloading state and a situation of transmission experience of the UE cannot be obtained in a moving process of the UE in the related art. Thereby, the reasonable resource pre-configuration can be performed for the moving process of the UE, the resource allocation and utilization efficiency are improved, and the user experience is enhanced.
