Dual-Connectivity Packet Policy for Sensitive Data Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual connectivity technologies in the transition from 4G to 5G networks rely heavily on server feedback for TCP/IP split control, leading to long delays and inefficiencies, especially in scenarios where a unified network split for modems is lacking.
Innovation Solution
A method and device that enable a terminal device to connect to both a 4G and 5G network, allowing for data packets to be sent through both links based on application type, with sensitive data being duplicated to ensure accuracy and delay-insensitive data being sent without duplication to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data packets are duplicated and sent through both LTE and NR links for sensitive data, then transmission accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating transmission policies based on data packet types. Sensitive data packets (e.g., DNS, voice, game data) are duplicated through both LTE and NR links to ensure transmission accuracy, while non-sensitive data packets are sent only through the NR link to reduce power consumption. This selective approach optimizes the balance between reliability and energy usage.
2Reliability
If data is sent through both LTE and NR links, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments data packets into different categories (sensitive and non-sensitive) based on packet types such as DNS, voice, game data, and video data. This segmentation allows the system to apply different transmission policies to different data segments, simplifying the overall control logic while maintaining high reliability for critical data through dual-link transmission.
3Use of energy by moving object
If all data packets are sent through the NR link only, then power consumption is reduced, but transmission accuracy for sensitive data deteriorates
Solution Approach 1:
The patent implements dynamic transmission policy adjustment based on the current application scenario and data packet type. The system dynamically switches between single-link (NR only) and dual-link (LTE + NR) transmission modes, optimizing the balance between power consumption and transmission accuracy in real-time according to the sensitivity requirements of the data being transmitted.

AI summary
The present invention provides an electronic device, a method, and a chip for sending data. The method includes: When a terminal device is in a dual-connectivity state, the terminal device determines a foreground application that is currently being run. When the application that is being run in a foreground is a present application, the terminal device further determines whether that is being of to-be-sent data is a data packet of a present type or a hardware resource occupation status of the terminal device; and sends the data packet of the present type, respectively sends the two data packets through two links, to implement transmission accuracy of sensitive data.
