Adaptive Packet Compression for Low-Cost IoT Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT data transmission methods require complex hardware support and high costs to optimize power consumption and transmission efficiency, particularly in uplink data transmission, which is a significant challenge due to the need for cooperation between terminal and network elements.
Innovation Solution
A data transmission method that deletes duplicated information in data packets using compression strategies, allowing for reduced data transmission without additional hardware support, by querying and synchronizing compression capabilities and strategies between the terminal and server, thereby reducing the amount of data transmitted and saving costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard TCP/IP and 3GPP protocol transmission solutions are used, then transmission reliability is ensured, but device complexity and cost increase due to required hardware support and functional module implementation
Solution Approach 1:
The patent applies compression copying by storing previously transmitted data packets and reusing their content when identical data needs to be transmitted again. Instead of retransmitting the entire packet, the system references the stored copy, significantly reducing redundant transmission while maintaining data integrity and reliability.
Solution Approach 2:
The patent extracts and removes redundant information from data packets by comparing current packets with previously transmitted ones. The compression unit identifies and eliminates duplicate content, keeping only the essential unique information for transmission, thereby reducing complexity without sacrificing reliability.
2Quantity of substance
If compression transmission is implemented without standard protocol support, then data transmission volume is reduced, but compatibility and reliability may be compromised
Solution Approach 1:
The patent implements a universal compression mechanism that works across different protocol types (HTTP, TCP, UDP, etc.). The compression unit is designed to handle multiple protocol formats simultaneously, applying compression strategies that are compatible with various standard protocols while maintaining their inherent reliability features.
Solution Approach 2:
The patent dynamically adjusts compression parameters based on the specific protocol being used. Different compression strategies are applied depending on the protocol type, data characteristics, and network conditions, allowing the system to optimize data volume reduction while preserving protocol-specific reliability mechanisms.
3Quantity of substance
If local proxy server compression is used, then data compression is achieved, but additional network infrastructure and cost are required
Solution Approach 1:
The patent implements self-service compression where the terminal device itself performs the compression function. The terminal includes a compression unit that autonomously compresses data before transmission and a decompression unit that reconstructs data upon receipt, eliminating the need for external proxy servers or specialized network infrastructure while achieving significant compression ratios.

AI summary
Provided are a data transmission method and device. The method includes: processing a first data packet to be sent by using a compression strategy obtained in advance from a receiving end, deleting specified duplicated data comprised in the compression strategy in the first data packet; generating a second data packet to be sent from the processed first data packet, where the second data packet includes a modification record field for indicating the deleted duplicated data; and sending the second data packet to the receiving end.
