Multimedia Streaming Base Station Edge Caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless broadband networks face limitations in bandwidth and content distribution, relying on centralized servers and content delivery networks (CDNs) which incur significant capital and operational expenses, and do not effectively cache and deliver multimedia content at the edge without central server involvement.
Innovation Solution
A multimedia streaming base station capable of capturing, encoding, and transmitting local multimedia content within a wireless communication network, utilizing a heterogeneous multi-RAT node with dynamic mesh capabilities, allowing for local caching and distribution without reliance on CDNs or central servers, and incorporating features like encryption, GPS, and computing cloud components for efficient content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multimedia content is stored in centralized data centers or server farms, then content distribution control and revenue maximization are improved, but network bandwidth requirements and operational expenses increase
Solution Approach 1:
The patent implements edge caching at base stations, allowing content to be stored locally rather than centrally. This enables local quality improvement by serving content from the nearest cache, reducing the bandwidth burden on centralized servers while maintaining distribution control through coordinated cache management across the network.
Solution Approach 2:
The patent segments the centralized content delivery system into distributed edge caches at multiple base stations. This segmentation allows content to be divided and stored across multiple local nodes, reducing the load on any single centralized server and decreasing overall network bandwidth requirements through localized content delivery.
2Speed
If content delivery networks with multiple replicated servers are deployed, then content delivery speed is improved, but capital and operational expenses increase significantly
Solution Approach 1:
The patent makes base stations universal by enabling them to perform both traditional wireless communication functions and multimedia content caching/delivery functions. This multi-functionality eliminates the need for separate CDN infrastructure, achieving fast content delivery using existing base station resources rather than requiring additional replicated servers.
Solution Approach 2:
The patent enables base stations to serve themselves as content caches, eliminating the need for external CDN infrastructure. Each base station independently caches and delivers content to its local users, providing self-service content delivery that reduces both capital expenses and operational complexity compared to traditional CDN deployments.
3Length of moving object
If small cells cache content from central servers, then content is brought closer to users, but dependence on CDN or central server remains
Solution Approach 1:
The patent implements preliminary content caching at edge base stations before user requests occur. Base stations proactively cache multimedia content locally, enabling immediate local delivery without needing to fetch content from central servers at request time. This preliminary action reduces both delivery distance and dependence on central servers.
Solution Approach 2:
The patent extracts the content caching function from the centralized server architecture and places it directly at the edge base stations. This extraction removes the mandatory dependence on central servers for content delivery, allowing base stations to independently serve cached content while maintaining the ability to fetch from central servers only when necessary.
