Idle-State QoE Measurement Reporting for Wireless UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems are unable to effectively measure and report the quality of user experience (QoE) for services received by user equipment (UE) devices in idle or inactive states, limiting network optimization and service quality improvement.
Innovation Solution
The UE devices and base stations are equipped with processors and radios to receive, perform, and transmit QoE measurement configurations and reports, even in idle or inactive states, using systems like SIBs and MCCH for configuration and RRC connections for reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoE measurement is performed for services in idle/inactive states, then service quality monitoring capability is improved, but device complexity and power consumption increase
Solution Approach 1:
The QoE measurement function is segmented into independent measurement objects (different services, different QoE parameters) that can be selectively activated. The system divides the measurement capability into manageable units that can be configured independently for different service types and states, reducing overall system complexity while enabling comprehensive monitoring.
Solution Approach 2:
The QoE measurement system is designed with multi-functionality to handle various service types (broadcast, multicast, unicast) and different UE states (idle, inactive, connected) through a unified measurement framework. This universal approach allows the same measurement infrastructure to serve multiple purposes, reducing device complexity compared to having separate measurement systems for each service type and state.
2Measurement precision
If QoE measurement is performed in idle/inactive states, then network optimization capability is improved, but power consumption increases
Solution Approach 1:
The system implements periodic QoE measurement and reporting mechanisms where measurements are performed at configured intervals rather than continuously. This periodic action allows the UE to enter low-power states between measurements while still providing timely QoE feedback to the network, significantly reducing power consumption compared to continuous monitoring.
Solution Approach 2:
The network pre-configures QoE measurement parameters, thresholds, and reporting conditions before the UE enters idle/inactive states. This preliminary configuration allows the UE to perform measurements efficiently with pre-defined criteria, avoiding the need for complex real-time decision-making and reducing processing power consumption during idle/inactive states.
3Measurement precision
If QoE measurement configuration is provided for idle/inactive states, then service quality monitoring is improved, but signaling overhead increases
Solution Approach 1:
The system merges QoE measurement configuration with existing system information blocks (SIBs) and dedicated signaling messages that are already transmitted to UEs. By combining QoE configuration with existing signaling structures rather than creating separate dedicated signaling, the overhead is minimized while still providing comprehensive measurement coverage for idle and inactive states.
Solution Approach 2:
The network provides QoE measurement configuration selectively to UEs based on their service subscriptions, capabilities, and current state, rather than broadcasting comprehensive configuration to all UEs. This partial action approach ensures that only necessary UEs receive and process QoE configuration information, reducing overall signaling overhead in the network.
