Mobile Gateway Caching for Content Delivery Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content delivery architectures are not optimized for mobile devices, as they rely on caching mechanisms provided after internet routing, which does not effectively utilize caching benefits due to geographical spread and obscured information, leading to inefficiencies in content delivery to mobile devices.
Innovation Solution
A mobile gateway system is introduced with integrated caching mechanisms, allowing mobile gateways to directly communicate with caching gateways or content providers, enabling local content retrieval and caching within the mobile network domain, thereby optimizing content delivery by reducing the need for internet routing and enhancing performance, security, and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content delivery relies on traditional CDN architecture with caching after internet routing, then content can be delivered to mobile devices, but caching benefits are not effectively utilized due to geographical spread and obscured information
Solution Approach 1:
The patent deploys caching gateways within the mobile network domain before content reaches mobile devices, enabling preliminary caching actions. This allows content to be cached locally in the mobile network domain rather than relying on traditional CDN caching after internet routing, effectively utilizing caching benefits by placing caches closer to end users in advance.
Solution Approach 2:
The patent introduces a new dimension to content delivery by integrating caching mechanisms directly into the mobile network domain architecture. This creates a layered approach where content can be delivered through both traditional internet routing and optimized mobile network routing with local caching, effectively adding a spatial dimension closer to mobile devices.
2Productivity
If mobile gateways directly communicate with caching gateways within mobile network domain, then content delivery efficiency and latency are improved, but network architecture complexity increases
Solution Approach 1:
The patent merges the mobile gateway and caching gateway functions within the mobile network domain, creating an integrated architecture. This combining of functions allows direct communication between mobile gateways and local caching gateways, improving content delivery efficiency by eliminating the need for content to traverse the entire internet routing path while managing complexity through functional integration.
3Reliability
If traditional CDN architecture is used with internet routing, then content can be delivered broadly, but latency is increased due to geographical distance
Solution Approach 1:
The patent implements local caching gateways within the mobile network domain that are geographically distributed across different regions. This local quality approach allows content to be cached and delivered from locations closer to mobile devices, reducing geographical distance and latency while maintaining broad content delivery availability through the distributed nature of the caching gateways.

AI summary
In one embodiment, a method includes: receiving, from a mobile gateway associated with the computing system, a first request for first content provided by a content publisher, the first request being sent from a mobile device; determining, based on information associated with the first request and one or more policies, that the first content is to be provided to the mobile gateway through one or more caching gateways associated with the mobile gateway; identifying at least one of the one or more caching gateways to provide the requested first content; and sending, to the mobile gateway, first instructions configured to cause the mobile gateway to obtain the requested first content from the identified at least one caching gateway.
