Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If XR data is processed through conventional user equipment, then device complexity is reduced, but latency increases and immersion quality deteriorates
Solution Approach 1:
The patent transitions processing from the device dimension to the network dimension by introducing edge computing nodes distributed across the telecommunication network. This dimensional shift allows processing to occur closer to users without concentrating all complexity in centralized data centers, thereby reducing latency while distributing system complexity across multiple network nodes.
Solution Approach 2:
Edge computing devices serve as intermediaries between centralized data centers and end-user XR devices. These intermediaries perform real-time data processing and caching functions, reducing the distance data must travel and minimizing latency while distributing processing complexity across the network infrastructure rather than concentrating it in single locations.
2Area of stationary object
If wireless connectivity is extended to remote locations, then coverage area increases, but connection stability deteriorates causing disruptions
Solution Approach 1:
The patent implements local quality by deploying edge computing resources and caching mechanisms at distributed locations throughout the network, including remote areas. This ensures that even when users are in remote locations with potentially weaker connections, processed XR content and data are available locally at edge nodes, maintaining connection stability and reducing dependency on continuous high-speed wireless links.
3Power
If real-time processing is performed at centralized data centers, then processing power is sufficient, but transmission latency increases
Solution Approach 1:
The patent segments the centralized data center processing function into distributed edge computing nodes across the telecommunication network. Each edge node handles local XR data processing requests, eliminating the need for all data to travel to centralized data centers. This segmentation maintains sufficient processing power across the system while dramatically reducing transmission latency by processing data closer to its source and destination.
4Speed
If XR content is cached locally, then access speed increases, but cache management complexity increases
Solution Approach 1:
The patent implements self-service through automated cache management systems at edge computing nodes that autonomously pre-fetch and store XR content based on predicted user needs, event schedules, and historical access patterns. This eliminates the need for manual cache management while maintaining high access speeds, as the system automatically determines what content to cache and when to update it based on real-time and historical data.
Data Source
AI summary
Systems and methods are provided for providing real-time virtual viewing content of a live event to a user equipment on a wireless communications network. Source information of the live event, which is processed on an edge computing device located within a threshold distance of the live event, is provided to a first user equipment. A second user equipment requesting to view the live event is identified, and the same source information that was provided to the first user equipment is provided to the second user equipment. Based on the same source information, the first user equipment is presented with a first virtual view at a first time that is different from a second virtual view presented to the second user equipment at the first time.
