AT Command Interface for 5G NR QoE Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack AT commands to support fifth generation (5G) new radio (NR) quality of experience (QoE) management, including mechanisms for configuration, activation, deactivation, mobility support, and reporting of QoE measurements.
Innovation Solution
Implementing AT commands to facilitate the configuration and reporting of QoE measurements by controlling the behavior of the mobile termination (MT) through a terminal adapter (TA), enabling the transmission of QoE application layer configuration and measurement reports to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If AT commands are implemented to support 5G NR QoE management, then QoE measurement capability and network management efficiency are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent segments QoE management into distinct AT commands for different functions: configuration management (+CQOEAMC), measurement reporting control (+CQOEAMR), and result code handling. This modular approach allows the system to implement comprehensive QoE management while maintaining manageable complexity through functional decomposition.
Solution Approach 2:
The AT command framework provides universal functionality for QoE management across multiple 5G NR scenarios including multimedia services, per-slice measurements, and RAN overload handling. A single standardized command structure serves multiple QoE management purposes, reducing overall system complexity through reuse.
2Manufacturing precision
If unsolicited result codes are implemented for QoE measurement reporting, then real-time QoE feedback capability is improved, but communication protocol complexity increases
Solution Approach 1:
The patent implements unsolicited result codes (+CQOEAMR) that automatically report QoE measurement results from the MT to the TE without requiring explicit request-response cycles. This feedback mechanism enables real-time QoE monitoring while simplifying the interaction model compared to traditional polling approaches.
Solution Approach 2:
The MT autonomously generates and transmits unsolicited result codes containing QoE measurement data when measurement events occur, without waiting for TE requests. This self-service approach improves measurement reporting timeliness and reduces protocol overhead by eliminating unnecessary request messages.
3Adaptability or versatility
If multiple simultaneous QoE measurements are supported, then QoE monitoring comprehensiveness is improved, but processing load and resource consumption increase
Solution Approach 1:
The patent enables dynamic configuration of QoE measurements through AT commands, allowing the TE to activate or deactivate specific measurement types based on current service requirements. The system can adaptively manage multiple simultaneous measurements for different multimedia services or slices while conserving resources by only performing measurements that are currently needed.

AI summary
A user equipment (UE) implements a terminal equipment (TE), a mobile termination (MT) and a terminal adapter (TA). The UE transmits, by the TE, an attention (AT) command for quality of experience (QoE) application layer configuration to the TA, wherein the AT command is configured to control a presentation of an unsolicited return code in response to a radio resource control (RRC) message received by the UE from a network comprising an application layer measurement configuration information element (IE) and receives, by the TE, the unsolicited result code comprising one or more parameters related to new radio (NR) QoE application layer measurements and associated with a measurement configuration application layer ID, wherein the one or more parameters in the unsolicited result code are received from the network in the application layer measurement configuration IE.
