Dual SIM Link Quality Evaluation and Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in mobile networks using dual SIM dual active (DSDA) configuration often experience degraded transmission quality due to the reliance on a primary SIM card link, especially during the initial deployment stages of new network technologies like 5G.
Innovation Solution
A data transmission method that evaluates the transmission quality of the primary card link and compensates for lower quality by utilizing the secondary card link, thereby ensuring load fault tolerance and maintaining data transmission quality through link balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is performed using the primary card link, then the transmission speed is improved, but the transmission quality deteriorates
Solution Approach 1:
The patent changes the parameter of transmission path selection by introducing link quality evaluation as a dynamic parameter. The system monitors transmission quality parameters (such as signal strength, packet loss, latency) and adjusts the data transmission path based on real-time quality assessment, transitioning from static primary card link usage to dynamic path selection based on quality parameters
Solution Approach 2:
The patent introduces a link quality evaluation mechanism as an intermediary between the data transmission process and the selection decision. This intermediary component continuously assesses the quality of the primary card link and triggers compensation actions when quality deteriorates, acting as a mediator that coordinates between transmission and quality monitoring functions
2Area of stationary object
If the primary card link is used for data transmission, then the network coverage is improved, but the transmission stability deteriorates
Solution Approach 1:
The patent implements beforehand cushioning by establishing a secondary card link as a backup transmission path before the primary link fails. The system pre-configures the secondary link and maintains its readiness, so when the primary link experiences instability or quality deterioration, the secondary link can immediately compensate without interruption, providing a cushion against transmission failures
Solution Approach 2:
The patent introduces feedback mechanisms where the link quality evaluation continuously monitors the stability of the primary card link and provides feedback to the transmission control system. When instability is detected through quality parameter degradation, the feedback triggers a switch to the secondary link, creating a closed-loop control system that maintains transmission stability
3Adaptability or versatility
If dual SIM dual active configuration is implemented, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a unified link quality evaluation and compensation mechanism that works across different SIM card configurations. The same quality evaluation framework and compensation logic can be applied whether using primary/secondary card links or other dual-SIM modes, making the system adaptable to various network configurations without requiring separate handling for each scenario
Solution Approach 2:
The patent implements self-service by enabling the system to automatically monitor link quality, detect deteriorations, and switch to backup links without external intervention. The dual SIM configuration automatically manages its own reliability through built-in quality evaluation and compensation mechanisms, reducing the need for manual configuration or external control

AI summary
The disclosure relates to a data transmission method and device based on a mobile network, and a storage medium. The data transmission method based on the mobile network is applied to a terminal. The terminal is configured with a primary card link and a secondary card link based on DSDS/DSDA. The method includes: transmission quality evaluation is performed on the primary card link when the primary card link is applied to perform data transmission of the mobile network to obtain a first transmission quality evaluation value (S11); and the data transmission of the mobile network performed by the primary card link is compensated through the secondary card link in response to that the first transmission quality evaluation value is lower than a transmission quality evaluation threshold (S12).
