Web Page Content Pre-Download for Unstable Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile users face difficulties in browsing web page content due to unstable network signals, which often result in slow loading or inability to access web pages, especially in environments without reliable WIFI or GPRS connections.
Innovation Solution
A method and apparatus for downloading web page content involves obtaining a list of web page link addresses and sub-level links, and downloading the content when a predetermined condition is met, such as in a stable network environment, allowing for offline access and seamless browsing even in unstable network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If web page content is accessed in real-time over mobile networks, then network connectivity is required, but network signals are unstable causing slow loading or inability to access content
Solution Approach 1:
The patent applies preliminary action by downloading web page content in advance when network conditions are good (WIFI environment). The system pre-fetches and caches web page content, images, and other resources before the user actually needs to access them, so that when network conditions deteriorate (subway, moving vehicle), the content is already available locally for immediate access without requiring real-time network connectivity.
2Adaptability or versatility
If web page content is downloaded in advance, then offline access is enabled, but device storage space is consumed
Solution Approach 1:
The patent applies local quality by selectively caching only the web page content that the user is most likely to access again, rather than storing entire websites. The system analyzes user browsing behavior patterns and prioritizes caching frequently visited pages, while using smaller cache sizes for less frequently accessed content. This allows offline access capability while optimizing storage space utilization based on actual user needs.
Solution Approach 2:
The patent implements a hierarchical caching structure where web page content is stored in multiple layers: frequently accessed content is cached in larger capacity, while less frequently accessed content is stored in smaller capacity or compressed formats. The caching system nests multiple levels of storage optimization, with intelligent eviction policies that remove or compress less important content when storage space is limited, allowing offline access while managing device storage constraints.
3Loss of information
If continuous downloading is performed to ensure content availability, then content freshness is improved, but network energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing scheduled content updates instead of continuous downloading. The system checks for content updates at predetermined intervals (e.g., daily, weekly) based on the type of web page and user behavior patterns. For news content, updates may occur more frequently (daily), while for reference materials, less frequent updates (weekly or monthly) are sufficient. This periodic update mechanism ensures content remains relatively fresh while significantly reducing network energy consumption compared to continuous synchronization.
Solution Approach 2:
The patent implements a feedback mechanism where the system monitors user access patterns, content age, and storage availability to dynamically adjust update frequency. When users frequently access certain content, the system increases update frequency for that content. When storage space is low or user activity is minimal, update frequency is reduced. This feedback-driven approach optimizes the balance between content freshness and energy consumption based on actual usage conditions rather than following a fixed schedule.

AI summary
A method and apparatus for downloading web page content. The method comprises obtaining a downloading list containing the following content according to target downloading content that a user needs to download: web page link addresses corresponding to the target downloading content and sub-level web page link addresses of the web page link addresses; and when a condition of a downloading mode corresponding to the target downloading content is met, downloading the web page content according to the web page link addresses in the downloading list.
