Server Data Compression for Mobile Network Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems face inefficiencies in bandwidth usage, particularly in mobile networks where high-quality content with significant data volume is transferred over limited bandwidth, leading to increased latency and reduced performance.
Innovation Solution
A communication system that dynamically compresses data objects based on available bandwidth, using a server to calculate the time required for uncompressing and transferring files, optimizing the compression level to minimize overall transfer time, and utilizing a mapping table to account for varying decompressing abilities of user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data objects are transferred uncompressed over mobile networks, then transfer speed is faster, but bandwidth efficiency deteriorates due to limited network capacity
Solution Approach 1:
The patent applies dynamics by making the compression level adjustable and adaptive rather than fixed. The server dynamically selects compression parameters based on real-time conditions including available bandwidth, object size, and user equipment decompression capabilities, allowing the system to optimize between transfer speed and bandwidth efficiency for each specific scenario
Solution Approach 2:
The patent changes the parameter of data representation by applying different compression levels to data objects. The server can transform the same object into multiple compressed versions with varying compression ratios, selecting the appropriate parameter (compression level) based on current network conditions and device capabilities to resolve the contradiction between transfer speed and bandwidth usage
2Quantity of substance
If data objects are compressed before transfer, then bandwidth efficiency is improved, but uncompressing time increases at the user equipment
Solution Approach 1:
The patent applies partial action by using selective compression rather than compressing all data objects uniformly. The server evaluates each object's characteristics (size, type, compressibility) and applies compression only when beneficial, using partial compression levels rather than maximum compression, thereby reducing uncompressing time while still achieving bandwidth efficiency for suitable objects
Solution Approach 2:
The patent applies preliminary action by pre-calculating and storing multiple compressed versions of data objects at the server before transfer. The server prepares compressed versions in advance with different compression levels, so when a request arrives, the appropriate pre-compressed version can be selected and transferred immediately, reducing both transfer time and uncompressing time at the user equipment
3Quantity of substance
If compression is applied to all data objects, then bandwidth utilization is maximized, but processing overhead increases at the server
Solution Approach 1:
The patent applies local quality by treating different data objects differently based on their specific characteristics. Rather than applying uniform compression to all objects, the server evaluates each object's compressibility, size, and type locally, applying compression only where it provides net benefit. This selective approach maximizes bandwidth utilization for suitable objects while avoiding unnecessary processing overhead for objects where compression would not help
