RRC State Initiation for Threshold-Triggered QoE Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively report Quality of Experience (QoE) measurements from User Equipment (UE) in Radio Resource Control (RRC) idle or inactive states, leading to suboptimal Quality of Service (QoS) without the ability to adjust configurations for Multicast Broadcast Services (MBS) transmission.
Innovation Solution
UEs are configured with threshold values for application layer measurements during RRC idle/inactive states, initiating a transition to RRC connected state when measurement values meet these thresholds, allowing for optimized MBS transmission adjustments by the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If UEs remain in RRC idle or inactive state to save energy, then energy consumption is reduced, but the ability to report QoE measurements and receive optimized MBS transmission configurations is lost
Solution Approach 1:
The UE autonomously performs application layer measurements and compares them against configured thresholds without needing network intervention. When the threshold is met, the UE self-initiates the RRC connection transition, eliminating the need for continuous network monitoring while maintaining measurement reporting capability.
Solution Approach 2:
The network pre-configures the UE with application layer measurement parameters and thresholds before the UE enters idle/inactive state. This preliminary configuration enables the UE to perform measurements and make autonomous decisions about when to transition back to connected state, ensuring measurement reporting capability is maintained without continuous network engagement.
2Loss of information
If UEs transition to RRC connected state to report QoE measurements, then measurement reporting capability is improved, but energy consumption increases
Solution Approach 1:
The system changes the operational parameters by introducing threshold-based triggering mechanisms. Instead of continuous connected state or completely passive idle state, the UE monitors application layer parameters (throughput, delay, buffer status) and only transitions to connected state when specific parameter thresholds are met, optimizing the balance between reporting capability and energy consumption.
3Adaptability or versatility
If the network continuously monitors UEs in idle state to optimize MBS transmission, then service optimization is improved, but network complexity and signaling overhead increase
Solution Approach 1:
The system implements a feedback mechanism where UEs autonomously measure application layer parameters and provide implicit feedback by transitioning to connected state when thresholds are met. The network receives this feedback through the connection transition request, which includes measurement information, enabling optimized MBS transmission configuration without requiring continuous active monitoring or complex signaling infrastructure.

AI summary
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the initiation for an RRC connected state. The method comprises receiving, from a second device, information related to a threshold value associated with a configuration of an application layer measurement performed by the first device: performing, during an RRC idle or inactive state, the application layer measurement based on the configuration; and in accordance with a determination that a measured value satisfies the threshold value, initiating a process for entering an RRC connected state. In this way, the UE may report the measurement by switching to the RRC connected state and meanwhile the transmission may be adjusted/optimized by the gNB without guiding the UE to the RRC connected state.
