Adaptive Measurement Gap Configuration for Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measurement gap configurations in mobile communication networks can disrupt real-time applications such as virtual reality (VR) and augmented reality (AR), leading to poor user experience due to data interruptions during neighbor cell measurements.
Innovation Solution
A method where a network node determines the traffic type and configures adaptive measurement gaps by setting a measurement gap repetition period or length based on conditions such as video frame rate or discontinuous reception (DRX) cycle, and transmits this configuration to user equipment (UE).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measurement gap is configured for neighbor cell measurement, then the UE can perform cell measurements, but the real-time application service quality deteriorates due to data interruptions
Solution Approach 1:
The measurement gap configuration is made dynamic by adapting the measurement gap repetition period (MGRP) and measurement gap length (MGL) based on the detected traffic type. For real-time applications like VR/AR, the system dynamically adjusts or suspends measurement gaps to maintain service quality, while for non-real-time applications, standard measurement gaps are applied. This dynamic adaptation resolves the contradiction by making the measurement gap behavior flexible rather than fixed.
Solution Approach 2:
The system changes the parameters of the measurement gap configuration (specifically MGRP and MGL) based on the traffic type detected from uplink signals. By modifying these parameters adaptively, the system can prioritize real-time application data transmission over measurement activities when necessary, thereby maintaining service quality while still enabling measurements when appropriate.
2Measurement precision
If measurement gaps are used for neighbor cell measurement, then the UE can measure neighboring cells, but data transmission is interrupted causing poor user experience
Solution Approach 1:
The measurement gap configuration is dynamically adjusted based on traffic type detection. For real-time applications requiring continuous data transmission, the system dynamically reduces or suspends measurement gaps, thereby maintaining data transmission continuity. For non-real-time applications, standard measurement gaps are applied, allowing both measurement and acceptable data transmission.
Solution Approach 2:
The system changes the measurement gap parameters (MGRP and MGL) based on the detected traffic characteristics. By adjusting these parameters adaptively, the system optimizes the balance between measurement activities and data transmission, ensuring high productivity for real-time applications while still enabling necessary measurements.
3Measurement precision
If the network node configures measurement gaps, then the UE can perform measurements, but the service quality of real-time applications deteriorates
Solution Approach 1:
The network node detects the traffic type from uplink signals transmitted by the UE, creating a feedback mechanism. Based on this feedback about the current traffic characteristics, the network node adaptively adjusts the measurement gap configuration. This feedback loop enables the system to maintain high service quality for real-time applications by reducing measurements when necessary, while still performing measurements when the traffic allows.
Solution Approach 2:
The network node changes the measurement gap parameters (MGRP and MGL) based on the detected traffic type feedback. For real-time applications with strict quality requirements, the parameters are adjusted to minimize impact on service quality, while for other traffic types, standard measurement parameters are applied.
