Wireless Distribution System Proxy Caches for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bandwidth limitations in delivering live television and video content in real-time over telco and mobile operator networks, and the challenge of providing location-specific advertisements to portable devices that traverse different geographic areas.
Innovation Solution
Implementing wireless distribution system proxy caches at mobile network operator points to cache television content and advertisements, and using device location services to update content and ads based on the current location of client devices, enabling targeted advertising and efficient content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If television content is delivered in real-time over wireless networks, then live television and video content can be distributed to client devices, but bandwidth limitations prevent efficient delivery
Solution Approach 1:
The system performs preliminary actions by caching television content data in proxy caches before it is requested by client devices. The proxy caches store content data from content services, so when clients request content, it can be delivered immediately from the cached copy rather than streaming in real-time from the source, thus resolving the bandwidth limitation while maintaining real-time delivery capability.
2Adaptability or versatility
If local advertisements are distributed within a fixed geographic area, then targeted advertising can reach consumers in that area, but portable devices moved through different geographic areas cannot receive updated location-specific advertisements
Solution Approach 1:
The system implements dynamics by making the advertisement distribution adaptive to the client's current location. The device location service continuously monitors the client device's geographic position and dynamically updates the advertising locale. When the device moves to a new geographic area, the system automatically retrieves and distributes location-specific advertisements from the proxy cache, enabling seamless transition between different advertising regions without increasing system complexity.
3Loss of energy
If proxy caches are implemented at wireless distribution points, then bandwidth usage is optimized by caching content data, but the system complexity increases
Solution Approach 1:
The system introduces proxy caches as intermediary components between content services and client devices. These proxy caches act as mediators that store content data locally at wireless distribution points, reducing the need for continuous bandwidth consumption from the content service to multiple clients. The intermediary proxy cache system manages content storage and retrieval, optimizing bandwidth usage while the modular design keeps system complexity manageable through clear separation of functions.

AI summary
In embodiments of wireless distribution system proxy caches, a mobile network operator receives requests for television content from client devices, and communicates one of the requests to a content service that provides the television content for distribution to the client devices. Proxy caches are implemented to cache content data of the television content prior to the cached content data of the television content being wirelessly communicated to the client devices. The proxy caches are located at wireless distribution points of the mobile network operator, and the wireless distribution points communicate the cached content data of the television content from the proxy caches to the client devices.
