Dynamic Edge-Based MBS for Threshold-Driven Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for delivering content to multiple users interested in the same content simultaneously in a particular location are inefficient, consuming excessive computing and networking resources and providing a poor user experience by independently utilizing 5G MBS and edge content caching.
Innovation Solution
A network edge system that provides dynamic edge-based MBS, intelligently deploying 5G MBS and edge content caching in a codependent manner, monitoring consumption patterns to trigger multicast based on thresholds, reducing network congestion and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unicast transport is used to deliver content to multiple users, then content can be delivered to individual users, but computing and networking resources are consumed inefficiently
Solution Approach 1:
The system dynamically switches between unicast and multicast delivery modes based on real-time monitoring of user demand thresholds. When the number of users requesting the same content exceeds a threshold, the system transitions from unicast to multicast delivery, and vice versa. This dynamic adaptation resolves the contradiction by optimizing resource efficiency while maintaining individualized content delivery capability.
2Productivity
If 5G MBS and edge content caching are utilized independently, then content delivery can be provided, but user experience is poor and resource usage is inefficient
Solution Approach 1:
The system merges 5G MBS and edge content caching into a unified hybrid delivery framework. The edge content caching system caches content locally, and when demand thresholds are met, seamlessly transitions to 5G MBS for efficient multicast delivery. This integration resolves the contradiction by improving delivery performance through coordinated operation while managing complexity through automated threshold-based switching logic.
3Loss of energy
If multicast delivery is used for content, then network efficiency is improved for multiple users, but implementation complexity increases
Solution Approach 1:
The system implements continuous monitoring of user demand with threshold-based feedback control. When the number of users requesting the same content exceeds a predefined threshold, the system automatically activates multicast delivery. When demand falls below the threshold, it switches back to unicast or edge caching. This feedback mechanism resolves the contradiction by enabling efficient multicast operation only when beneficial, thereby improving networking resource efficiency while keeping implementation complexity manageable through automated decision-making.
Data Source
AI summary
A device may receive content from an application server based on a user equipment (UE) generating a request to view the content over a unicast bearer, and may store the content in a temporary data structure. The device may receive a redirected request to view the content from the UE, and may provide the content over the unicast bearer to the UE based on the redirected request. The device may receive, from the UE, a unicast consumption of the content by the UE and a location of the UE, and may determine whether interest in the content for the location satisfies a threshold based on the unicast consumption. The device may initiate multicast and broadcast service (MBS) core functions with computing resources to utilize for an MBS for the content at the location based on the interest in the content for the location satisfying the threshold.
