QoE Measurement Configuration for Inter-RAT Handover Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack support for QoE measurement collection continuity during intra-system inter-RAT mobility, specifically in scenarios where the source and target radio access technologies (RATs) have different capabilities for QoE measurements per service type.
Innovation Solution
A method and apparatus are provided to support QoE measurement collection continuity by configuring and managing QoE measurements across inter-RAT handovers, involving a RAN node that transmits specific QoE measurement configurations and continuity information to a UE, ensuring seamless transition and reporting of QoE measurements across different RATs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoE measurement configuration is maintained during inter-RAT handover, then measurement continuity is improved, but system complexity increases due to different RAT capabilities
Solution Approach 1:
The source RAN node performs preliminary actions by selecting and configuring the appropriate QoE measurement set (first or second) before handover occurs. The configuration includes pre-determining which QoE measurements to continue or release based on target RAT capabilities, thereby simplifying the handover execution phase while ensuring measurement continuity.
Solution Approach 2:
The patent applies parameter changes by switching between different QoE measurement configurations (first set with multiple measurements per service type, second set with single measurement per service type) based on RAT type. This allows the system to adapt measurement parameters to match target RAT capabilities while maintaining continuity where possible.
2Measurement precision
If multiple QoE measurements per service type are supported, then measurement precision is improved, but adaptability to different RATs deteriorates
Solution Approach 1:
The patent segments QoE measurements into two distinct sets: a first set supporting multiple measurements per service type for high-precision requirements, and a second set supporting single measurement per service type for broad RAT compatibility. The system selectively applies the appropriate segment based on target RAT capabilities and service requirements.
Solution Approach 2:
The system dynamically switches between the first and second QoE measurement sets based on real-time conditions including target RAT type, service type requirements, and handover context. This dynamic adaptation allows the system to optimize for either precision or compatibility as needed.

AI summary
Methods and apparatuses of supporting QoE measurement collection are provided. An exemplary method may include: transmitting, to a UE (102), first information indicating configuration of at least one set of QoE measurement, wherein, each set of QoE measurement includes one or more QoE measurements for a same service type and different sets of QoE measurement are for different service types; and transmitting, to the UE (102), second information indicating configuration of at least one QoE measurement in response to an inter-RAT handover to a target RAN node, wherein the at least one QoE measurement is selected from the at least one set of QoE measurement, and different QoE measurements of the at least one QoE measurement are for different service types.
