Terminal Interruption Delay Reporting for QoS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack the ability for base stations to accurately control Quality of Service (QoS) due to unpredictable interruption delays caused by varying timing relationships between measurement reports and T310 timers, making it difficult to determine if current configuration parameters and policies satisfy QoS requirements.
Innovation Solution
A terminal information reporting method that allows terminals to send interruption delays or specific identifiers representing timing relationships to base stations, enabling the base stations to determine if current configurations meet QoS standards and adjust parameters accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different behavior modes are configured for timing relationship between measurement report and T310, then terminal communication flexibility is improved, but interruption delay becomes random and unpredictable
Solution Approach 1:
The terminal feeds back the actual interruption delay (or its identifier) to the base station after experiencing the timing relationship between measurement report and T310. This feedback mechanism allows the base station to learn the actual interruption delay characteristics and adjust configurations accordingly, transforming the previously random delay into a controllable parameter through closed-loop optimization.
Solution Approach 2:
The base station adjusts configuration parameters (such as T310 duration, measurement report triggering conditions, or behavior mode selections) based on the feedbacked interruption delay information. By dynamically changing these parameters, the system optimizes the balance between communication flexibility and interruption delay predictability, ensuring QoS requirements are met.
2Ease of operation
If base station cannot control interruption delay, then terminal behavior freedom is maintained, but quality of service control capability is lost
Solution Approach 1:
The terminal measures and feeds back the interruption delay (or its identifier representing timing relationship) to the base station. This feedback enables the base station to understand the actual impact of different configurations on interruption delay while terminals maintain their operational freedom. The base station uses this information to adjust configurations for QoS optimization.
Solution Approach 2:
The terminal autonomously measures its own interruption delay and provides this self-assessed information to the base station. This self-service approach allows the terminal to contribute to system optimization without requiring complex base station-controlled measurement mechanisms, preserving terminal independence while enabling QoS control.
3Reliability
If base station adjusts configuration parameters to improve QoS, then service quality is improved, but system complexity increases
Solution Approach 1:
The complex task of measuring and determining interruption delay is extracted from the base station and assigned to the terminal. The terminal autonomously measures the timing relationship between measurement report and T310, then feeds back the result (or its identifier). This extraction simplifies base station functionality while maintaining QoS control capability through the feedback mechanism.
Solution Approach 2:
The interruption delay identifier serves as an intermediary between the terminal's operational freedom and the base station's QoS control needs. Instead of directly controlling complex timing relationships, the base station uses the feedbacked identifier to select appropriate configurations from predefined options, simplifying the control process while achieving QoS optimization.

AI summary
Embodiments of the present invention provide a terminal information reporting method and a related device, which enables a base station to learn an interruption delay, and therefore can control quality of service according to the interruption delay. The method includes: obtaining, by a first terminal, first information, where the first information includes an interruption delay or a first identifier or a second identifier, where the first identifier represents a timing relationship between a moment at which the first terminal triggers or sends a measurement report and a first timer, and the second identifier represents a timing relationship between a moment at which the first terminal initiates connection reestablishment and the first timer; and sending the first information to a base station. The present invention is applicable to the field of communications.
