Dual-Channel Data Transmission with Proxy Deduplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in terminal devices face challenges with high latency and packet loss due to unstable network environments, particularly in Wi-Fi and cellular networks, which affect applications requiring low latency and high stability, such as online gaming.
Innovation Solution
The method involves using two different data channels for transmitting application packets: a non-short-range wireless data channel (such as Wi-Fi or cellular) and a short-range wireless data channel (such as Bluetooth or near field communication). This dual-channel approach improves data transmission stability and reduces power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single data channel (Wi-Fi or cellular) is used for data transmission, then the device complexity is low, but the data transmission stability and reliability are poor due to high latency and packet loss in unstable network environments
Solution Approach 1:
The patent divides the data transmission path into multiple independent channels: a first data channel (Wi-Fi or cellular network) and a second data channel (short-range wireless communication). By segmenting the transmission path, the system can select alternative routes when one channel experiences packet loss or high latency, thereby improving data transmission reliability without requiring a complete redesign of the communication architecture.
Solution Approach 2:
The patent introduces a proxy server as an intermediary component that receives data packets from multiple channels, performs deduplication processing, and forwards packets to the target server. This intermediary resolves the complexity of multi-channel management by centralizing the packet consolidation logic, allowing the terminal device to maintain multiple transmission channels while the proxy server handles the coordination and deduplication.
2Loss of time
If dual-channel data transmission is implemented, then the air interface packet loss rate and data latency are reduced, but the device complexity increases due to multiple routing devices and channels
Solution Approach 1:
The patent establishes a proxy server in advance that is configured to receive packets from multiple channels and perform deduplication. This preliminary setup allows the system to quickly switch between channels during data transmission without requiring complex real-time decision-making at the terminal device, thereby reducing data latency while managing complexity through pre-configuration.
Solution Approach 2:
The terminal device autonomously transmits data packets through multiple channels simultaneously without requiring complex coordination or control mechanisms. Each channel operates independently, and the proxy server automatically handles packet deduplication and selection, allowing the system to achieve low latency through parallel transmission while keeping the terminal device relatively simple.
3Use of energy by moving object
If traditional single-channel transmission is used, then the device structure is simple, but the power consumption is high due to reliance on high-power Wi-Fi or cellular networks
Solution Approach 1:
The patent applies different transmission modes to different spatial scales: for short-distance communication, it uses low-power short-range wireless channels (Bluetooth, NFC), while for long-distance communication, it uses high-power wide-area networks (Wi-Fi, cellular). This local quality approach optimizes power consumption by selecting the most energy-efficient channel for each specific transmission scenario while maintaining data transmission reliability through the proxy server's deduplication mechanism.

AI summary
Embodiments of the present invention disclose a data transmission method and apparatus, a device, and a computer storage medium. The method comprises: obtaining, from a target application, an application data packet to be transmitted; transmitting the application data packet to a first routing device over a network data channel, and then transmitting the application data packet to a proxy server by means of the first routing device, while simultaneously transmitting the application data packet to a second routing device over a short-range wireless data channel different from the network data channel, and then transmitting the application data packet to the proxy server by means of the second routing device; and transmitting, by means of the proxy server, the application data packet to an application server on the basis of a deduplication mechanism.
