Engineering Contradiction Analysis
1Productivity
If the terminal uses EN-DC dual connection mode for data transmission, then data transmission rate is improved, but power consumption increases and transmission stability deteriorates when signal quality is poor
Solution Approach 1:
The patent implements dynamic switching between EN-DC dual connection mode and 4G single connection mode based on real-time monitoring of signal quality and data transmission rates. When signal quality is good, the system uses EN-DC mode for high-speed transmission; when signal quality deteriorates or transmission rate becomes unstable, it switches to 4G mode to save power and maintain stable transmission.
Solution Approach 2:
The system monitors key parameters including signal quality metrics (RSRP, SINR) and data transmission rates in real-time. Based on these parameter changes, it dynamically adjusts the connection mode, transitioning between EN-DC and 4G modes to optimize the balance between transmission performance and power consumption.
2Productivity
If the terminal uses EN-DC dual connection mode, then data transmission rate is improved, but transmission stability deteriorates when signal quality is poor
Solution Approach 1:
The system continuously monitors signal quality (RSRP, SINR) and data transmission rates, using this feedback to determine when to switch between connection modes. When feedback indicates poor signal quality or unstable transmission, the system switches from EN-DC to 4G mode to maintain transmission stability.
Solution Approach 2:
The patent implements dynamic switching between connection modes based on real-time network conditions. The system adapts its connection strategy by transitioning from EN-DC mode (high speed but less stable in poor conditions) to 4G single connection mode (more stable in poor signal conditions), optimizing the balance between transmission rate and stability.
3Use of energy by moving object
If the terminal dynamically switches between EN-DC and 4G modes, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The terminal autonomously monitors its own signal quality and transmission performance, and automatically switches between connection modes without requiring manual intervention or complex external control systems. This self-service approach reduces power consumption while managing the complexity of mode switching through automated decision-making based on predefined criteria.
4Productivity
If the terminal monitors real-time data transmission rate, then transmission efficiency is optimized, but device complexity increases
Solution Approach 1:
The system implements monitoring of real-time data transmission rates and uses this feedback to optimize transmission efficiency. By continuously measuring transmission performance and comparing it against thresholds, the system can trigger mode switches when efficiency degrades, creating a closed-loop control mechanism that optimizes throughput while managing complexity through rule-based decision-making.

AI summary
A data transmission method, applied to a terminal that uses a dual connection mode of non-standalone networking for data transmission, includes: monitoring a network signal quality in the dual connection mode of non-standalone networking, and monitoring a real-time data packet transmission rate of a data packet transmitted and received by the terminal; and adjusting, based on the network signal quality and the real-time data packet transmission rate, the dual connection mode of non-standalone networking, which includes turning off the dual connection mode of non-standalone networking or maintaining the dual connection mode of non-standalone networking. Automatic and dynamic switching between EN-DC dual connection and single 4G network connection can be realized, without manually switching networks by users, such that effective transmission and reception of terminal data packets is ensured, and increase in power consumption caused by always relying on the EN-DC dual connection is avoid.
