Selective EN-DC Switching for UE Battery and Throughput Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) consumes more energy to maintain an EN-DC connection compared to an LTE connection alone, leading to faster battery drain, which may not be justified in situations where users do not perceive the benefits of the EN-DC connection.
Innovation Solution
The UE incorporates an EN-DC switcher to dynamically determine whether to use an EN-DC connection or an LTE connection based on factors such as display status, sensor data, application type, data type, charging status, and battery level, prioritizing LTE connection in scenarios where users are unlikely to perceive throughput benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If EN-DC connection is used to achieve higher throughput, then data transmission speed is improved, but battery drain rate increases
Solution Approach 1:
The system dynamically switches between EN-DC and LTE connections based on real-time conditions. The EN-DC switcher continuously monitors factors such as display status, sensor data, application type, data type, charging status, and battery level to determine the optimal connection mode, making the connection selection adaptive and dynamic rather than static
Solution Approach 2:
The system changes operational parameters by switching between different connection modes (EN-DC vs. LTE) based on multiple monitoring parameters. The EN-DC switcher evaluates various parameters including battery level, charging status, display status, and data characteristics to determine when to transition between connection types, optimizing the balance between throughput and energy consumption
2Productivity
If EN-DC connection is used to maintain high throughput, then data transmission performance is improved, but battery life decreases
Solution Approach 1:
The EN-DC switcher implements a feedback mechanism by continuously monitoring multiple factors including display status, sensor data, application type, data type, charging status, and battery level. This feedback loop enables the system to adjust connection modes based on real-time conditions, switching to LTE when battery life is low or EN-DC when throughput is needed
Solution Approach 2:
The system dynamically adjusts the connection mode based on real-time conditions. The EN-DC switcher continuously evaluates multiple parameters and switches between EN-DC and LTE connections as needed, making the system adaptive to changing user needs and battery status rather than maintaining a fixed connection type
3Speed
If EN-DC connection is enabled to provide superior data transmission, then throughput is improved, but energy consumption increases
Solution Approach 1:
The system changes the operational state by switching between EN-DC and LTE connections based on evaluated parameters. The EN-DC switcher monitors factors such as display status, sensor data, application type, data type, charging status, and battery level to determine when to transition between connection types, optimizing the balance between throughput and energy consumption
Solution Approach 2:
The system applies partial action by using EN-DC connection only when necessary and beneficial. Instead of continuously using the more energy-intensive EN-DC connection, the system selectively activates it based on specific conditions (high throughput needs, sufficient battery level, appropriate data type), thereby reducing overall energy consumption while maintaining performance when needed

AI summary
A user equipment (UE) may support establishing an E-UTRAN New Radio-Dual Connectivity (EN-DC) connection with a telecommunication network that involves both a Long-Term Evolution (LTE) connection and a fifth generation (5G) connection. However, the EN-DC connection may drain a battery of the UE more quickly than the LTE connection would alone. Accordingly, an EN-DC switcher executing on the UE can determine when the UE should use the LTE connection alone or use the EN-DC connection, for example based on factors that may indicate when a user of the UE is less likely to perceive improved throughput or other benefits of the EN-DC connection.
