Wireless Access System Backhaul Content Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face challenges in delivering high-quality services due to bandwidth bottlenecks, particularly in backhaul links, which become overwhelmed when multiple users request the same high-bandwidth content simultaneously, leading to issues like jitter, lost packets, and delayed content delivery.
Innovation Solution
Implementing a method where a wireless access system buffers the first instance of content and transmits it to multiple users requesting the same content, rather than transferring multiple instances over the backhaul link, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple instances of the same content are transferred over the backhaul link to satisfy multiple users, then each user can receive the content, but the backhaul bandwidth is wasted and becomes a bottleneck
Solution Approach 1:
The patent merges multiple content requests for the same content by buffering the first instance at the access system and reusing it for multiple users, thereby combining what would otherwise be separate content transfers into a single efficient operation
Solution Approach 2:
The access system creates a buffer copy of the content after receiving it from the backhaul link, allowing multiple users to access the same content without requiring separate content transfers over the backhaul, thus eliminating redundant copies
2Productivity
If backhaul bandwidth is increased to accommodate more users, then more users can access content simultaneously, but the cost and complexity of the network increases
Solution Approach 1:
The access system performs preliminary buffering of content after the first user requests it, so that when subsequent users request the same content, the buffered copy can be immediately served without requiring additional backhaul bandwidth or network infrastructure
3Productivity
If content is transferred to multiple users simultaneously over the backhaul link, then content availability is improved, but jitter and packet loss increase
Solution Approach 1:
The patent segments the content delivery process into two distinct paths: the backhaul link carries only a single content instance to the access system, while the access system's buffer handles multiple user requests locally, separating the content acquisition function from the content distribution function
Data Source
AI summary
A method disclosed herein comprises receiving first content into a wireless access system from a backhaul link between the wireless access system and a service system, transmitting the first content from the wireless access system to a first device served by the wireless access system, receiving a second packet communication from a second device served by the wireless access system wherein the second packet communication includes a second content request, processing the second packet communication to determine a second content identifier included in the second content request, processing the second content identifier to determine if the second content is the same as the first content, buffering the first content and transmitting the buffered first content to the second device, and transferring the second packet communication to a communication network to obtain the second content.
