Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices experience increased power consumption when performing data transmission with multiple access network devices, particularly in 5G non-standalone networking, which affects user experience.
Innovation Solution
A terminal device in dual-connectivity mode switches between LTE and NR links based on power saving mode, battery level, and temperature conditions, releasing the NR link when power or temperature thresholds are met, and restoring it when conditions improve, thereby reducing power consumption while maintaining user requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal device uses both NR link and LTE link for communication to meet user requirements, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic link selection based on real-time detection of power saving mode status, battery power levels, and temperature conditions. The terminal device dynamically switches between using NR link only, LTE link only, or both links based on current operational conditions, resolving the contradiction between communication performance and power consumption through adaptive behavior
Solution Approach 2:
The patent changes operational parameters (link selection) based on detected conditions such as power saving mode status, battery power thresholds, and temperature thresholds. By adjusting the communication link configuration according to these parameter changes, the system optimizes the balance between performance and energy consumption
2Use of energy by moving object
If the terminal device releases the NR link to reduce power consumption, then power saving is improved, but communication performance deteriorates
Solution Approach 1:
The patent employs feedback mechanisms where the terminal device continuously monitors power saving mode status, battery power levels, and temperature conditions. Based on this feedback, the system makes informed decisions about when to release the NR link and when to restore it, ensuring that power saving actions do not permanently compromise communication performance
Solution Approach 2:
The system dynamically adjusts link configuration based on real-time conditions. When power saving conditions are detected, the NR link is released; when conditions improve, the link is restored. This dynamic adjustment allows the system to optimize power saving while maintaining communication performance availability
3Productivity
If the terminal device maintains both NR link and LTE link for high performance communication, then communication performance is improved, but device temperature increases
Solution Approach 1:
The patent implements dynamic link management based on real-time temperature monitoring. When temperature exceeds the second preset value, the system dynamically releases the NR link to reduce thermal load. When temperature returns to acceptable levels, the link is restored, thereby managing temperature while maintaining communication performance availability
Solution Approach 2:
The system uses temperature feedback to make informed decisions about link configuration. The continuous monitoring of temperature conditions provides feedback that triggers appropriate responses (releasing or restoring NR link), creating a closed-loop system that manages thermal conditions while preserving communication performance

AI summary
This application provides a terminal device and a communication method. The terminal device is in a dual-connectivity network including an LTE link and an NR link, and when the terminal device detects that the terminal device is in a power saving mode, and/or when the terminal device detects that battery power of the terminal device is less than or equal to a first preset value, and/or when the terminal device detects that temperature of a rear cover of the terminal device is greater than or equal to a second preset value, the terminal device releases the NR link, and uses the LTE link for communication; or when the terminal device detects that the terminal device is in a non-power saving mode, and/or when the terminal device detects that the battery power of the terminal device is greater than the first preset value, and/or when the terminal device detects that the temperature of the rear cover of the terminal device is less than the second preset value, the terminal device restores the NR link and uses both the NR link and the LTE link for communication. In the foregoing technical solution, power consumption of the terminal device is reduced while a user requirement is met.
