Accelerator Module Stack for Radio Access Network Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for data services in cellular wireless communications networks leads to bandwidth bottlenecks, causing high latency and increased costs for providers, as advanced mobile devices consume significant bandwidth with applications like streaming video.
Innovation Solution
Implementing an accelerator module with a stack that reduces traffic through the radio access network by compressing data using techniques like Lempel-Ziv/deflate compression and de-duplication, and reconstructing content on the other side of the network to minimize latency and bandwidth usage, while also optimizing TCP sessions and HTTP protocol handshaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bandwidth capabilities are increased to satisfy user demands, then user service quality is improved, but operational costs increase
Solution Approach 1:
The accelerator module performs preliminary actions by caching content and pre-establishing TCP connections before they are needed. When a user requests content, the accelerator module can serve it directly from cache or reuse existing connections, avoiding the need to provision additional bandwidth capacity for predictable traffic patterns.
Solution Approach 2:
The accelerator module creates copies of frequently accessed content and stores them in local cache. Instead of transmitting the same content multiple times over the wireless network, the system serves local copies to users, significantly reducing bandwidth consumption while maintaining service quality.
2Productivity
If more bandwidth is allocated to data services, then user experience is improved, but network capacity requirements increase
Solution Approach 1:
The accelerator module merges multiple TCP connections into a single connection to the content provider. By aggregating traffic from multiple users and combining it into fewer connections, the system reduces overhead and maximizes the utilization of available bandwidth, effectively increasing data service capacity without proportionally increasing bandwidth requirements.
Solution Approach 2:
The accelerator module acts as an intermediary between users and the content provider network. It intercepts requests, serves content from local cache when possible, and manages TCP connections efficiently, thereby reducing the bandwidth burden on the wireless network while maintaining or improving user experience.
3Quantity of substance
If data transmission is optimized through compression, then bandwidth usage is reduced, but processing complexity increases
Solution Approach 1:
The accelerator module applies compression selectively rather than universally. It compresses content that benefits from compression while leaving already-compressed or text-based content unchanged. This partial application of compression reduces bandwidth usage for appropriate content types while minimizing unnecessary processing complexity.

AI summary
Various methods and communications devices to improve bandwidth utilization in a wireless communication network are provided. By way of example, efficient content delivery in a radio access network is achieved by using an accelerator module configured to implement a stack having, among others, a hypertext transfer protocol (HTTP) layer, a transmission control protocol (TCP) layer, and a de-duplication, Lempel-Ziv (LZ) compression/decompression, and caching layer.
