Local Cache Server for Wireless Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when multiple users simultaneously download the same content, it leads to inefficient resource utilization due to repeated transmission of the same data through the PGW, SGW, and eNB, causing resource occupation and reduced network efficiency.
Innovation Solution
Implementing a local cache server near the base station to store frequently requested content, allowing the system to transmit data only once to the cache server and then deliver it to multiple terminals, thereby reducing network load and improving service efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted from the content server to multiple terminals through the PGW and SGW in a wireless communication system, then each terminal can receive the requested content, but the same data is transmitted multiple times causing inefficient resource utilization and increased network load
Solution Approach 1:
The patent implements a cache server that pre-stores content data in the network infrastructure before actual user requests. When multiple terminals request the same content, the data is already cached and can be served directly without repeated transmissions from the original content server, thus performing the data preparation action in advance to avoid redundant transmissions
Solution Approach 2:
The patent introduces a cache server as an intermediary component between the content server and the terminals. This mediator stores copies of content data and intercepts requests from multiple terminals, serving them from the cache without requiring repeated communications with the original content server, thereby reducing network load and improving efficiency
2Reliability
If the same content is transmitted through the PGW, SGW, and eNB for each terminal request, then each terminal receives its requested data, but the network resources are occupied repeatedly reducing overall network efficiency
Solution Approach 1:
The patent creates copies of content data and stores them in a cache server within the network infrastructure. Instead of transmitting the same original data multiple times through the network for each terminal request, the system serves replicated copies from the cache, ensuring reliable content delivery while significantly reducing network throughput consumption
3Productivity
If a local cache server is introduced to store content data, then network resource utilization is reduced and service efficiency is improved, but the system complexity increases due to additional components
Solution Approach 1:
The patent introduces a cache server as an intermediary component that sits between the content server and the wireless network infrastructure. This mediator handles content storage and request interception, improving service efficiency by serving cached content locally while managing the additional system complexity through standardized integration with existing network elements

AI summary
The present invention relates to a wireless communication system and a method for managing a cache server in the wireless communication system, the invention includes a step for checking a regional cache server to transmit contents when a DNS (Domain Name System) request a message for receiving contents acquired from a terminal, and a step for transmitting the contents by the cache server according to a contents request message received from the terminal. These steps can prevent the same data from being transmitted several times through a wireless communication network. Therefore, network usage associated with the service is reduced, and the network can be used more efficiently.
