Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quality of experience (QoE) measurement and reporting for multimedia broadcast services (MBMS) in wireless communication systems lack specific configuration and reporting capabilities tailored to the capabilities of user equipment (UE) and service types, leading to inefficient QoE assessment and optimization.
Innovation Solution
A method and apparatus for configuring and reporting QoE measurements in wireless communication systems, where a terminal receives configuration information from a base station to perform QoE measurements based on specific RRC states, allowing for tailored measurement and reporting for MBMS services, enabling appropriate configuration according to UE capabilities and service types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If QoE measurement configuration is provided for MBMS services without considering UE capabilities and service types, then the measurement process is simplified, but the accuracy and relevance of QoE assessment deteriorates
Solution Approach 1:
The patent applies local quality by providing different QoE measurement configurations tailored to specific UE capabilities and service types. The base station determines appropriate measurement parameters, reporting formats, and configurations based on the particular characteristics of each UE and MBMS service, rather than using a uniform configuration for all cases. This ensures optimal measurement accuracy for each specific scenario.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting QoE measurement parameters such as measurement intervals, reporting thresholds, and configuration details based on UE capabilities, service types, and network conditions. This allows the system to optimize measurement precision for different scenarios while maintaining operational simplicity through automated parameter selection.
2Measurement precision
If QoE measurement configuration is tailored to each UE capability and service type, then QoE assessment accuracy is improved, but the device complexity and configuration overhead increases
Solution Approach 1:
The patent implements self-service by enabling the base station to automatically determine and configure appropriate QoE measurement parameters based on UE capabilities and service types. The system autonomously selects measurement configurations without requiring manual intervention or complex user setup, thereby reducing configuration complexity while maintaining high measurement accuracy through capability-aware parameter selection.
Solution Approach 2:
The patent applies dynamics by making QoE measurement configurations adaptive and flexible rather than static. The base station can dynamically adjust measurement parameters, reporting formats, and configuration details based on changing UE capabilities, service types, and network conditions. This dynamic approach allows the system to maintain optimal measurement accuracy while managing configuration complexity through automated adaptation.
3Ease of manufacture
If generic QoE measurement configuration is used for all MBMS services, then the system is easier to implement, but the ability to optimize for specific service types deteriorates
Solution Approach 1:
The patent applies universality by designing a QoE measurement configuration system that can serve multiple MBMS service types and UE capabilities through a unified framework. The base station implements a multi-functional configuration mechanism that automatically adapts to different service types (e.g., streaming, downloading, browsing) and UE capabilities, providing both ease of implementation through a single system and service-specific optimization through adaptive parameter selection.
Data Source
AI summary
The disclosure relates to a fifth-generation (5G) or a sixth-generation (6G) communication system for supporting higher data rates, especially, for performing quality of experience (QoE) measurement and reporting for multimedia broadcast service (MBS) services are provided. A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a base station, a message including information to configure an application layer measurement while the terminal is in a radio resource control (RRC) connected state, the information including a configuration of QoE measurements for multimedia broadcast service (MBS) broadcast, identifying whether the information further includes an indicator for identifying at least one RRC state for which the configuration is applied, and in case that the information further includes the indicator, performing the QoE measurements using the configuration, based on the indicator.
