Base Station Content Caching for Mobile Network Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks experience long transmission delays due to content sources needing to pass through third-party servers, mobile core networks, and mobile access networks, resulting in poor user experiences for mobile users accessing content.
Innovation Solution
A data storage method where a base station receives content source requests from a service capability exposure function, allowing direct storage and retrieval of content sources from the base station, bypassing the mobile core network and mobile access network, thereby shortening the transmission path and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If content source is moved to edge of mobile network, then transmission path length is reduced, but transmission delay remains long due to passing through mobile core network and air interface
Solution Approach 1:
The patent extracts the content source from the traditional third-party server location and places it directly at the base station (edge network node), removing it from the standard transmission path through core network and air interface. This extraction principle allows content to be delivered via a shortened path through the content delivery network, reducing both path length and transmission delay simultaneously.
2Device complexity
If content source is stored at third-party server, then network infrastructure complexity is reduced, but transmission delay increases due to long path through mobile core network
Solution Approach 1:
The patent implements preliminary action by pre-storing content sources at base stations before user requests arrive. The service capability exposure function receives content sources from third-party servers in advance and stores them at edge network nodes (base stations), so that when users request content, it can be immediately delivered through the shortened CDN path without waiting for retrieval from remote servers, thus reducing transmission delay without significantly increasing infrastructure complexity.
3Loss of time
If content is cached at base station, then transmission delay is reduced, but base station storage requirements increase
Solution Approach 1:
The patent applies universality by designing the base station to serve multiple functions: traditional cellular service provision and content source storage/delivery. The service capability exposure function enables base stations to act as both communication infrastructure and content delivery nodes, allowing them to store and deliver content sources for multiple applications and users simultaneously. This multi-functionality justifies the storage volume requirement by maximizing the utilization of existing base station resources.
