Solution Overview
Problem
Current cloud gaming technologies face challenges with bandwidth and latency issues, particularly in multisession remote gaming scenarios, which affect the quality of service and user experience, especially in augmented and virtual reality applications.
Innovation Solution
A distributed network architecture is implemented with a trusted operator network and a cloud-based remote gaming back office, utilizing a remote render system manager to instantiate and manage gaming sessions, edge routing for optimal network location, and a bandwidth manager to dynamically allocate resources, ensuring low latency and high-quality rendering across multiple sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cloud gaming services are deployed using conventional centralized datacenter architecture, then game rendering capability is improved, but network bandwidth consumption increases and latency worsens
Solution Approach 1:
The patent segments the centralized datacenter architecture into distributed edge computing nodes deployed at network edges (content delivery networks, mobile network edges). Each edge node handles local game rendering sessions, segmenting the monolithic datacenter into geographically distributed units that reduce network transmission distance and bandwidth consumption.
Solution Approach 2:
The patent introduces a new spatial dimension by deploying rendering infrastructure across the network edge rather than concentrating it in centralized datacenters. This dimensional shift from centralized to distributed edge locations reduces the average network distance between users and rendering services, thereby reducing bandwidth consumption and latency.
2Adaptability or versatility
If multiple gaming sessions are supported simultaneously in cloud gaming, then service coverage is improved, but network bandwidth requirements increase and quality of service deteriorates
Solution Approach 1:
The patent segments the network architecture into multiple edge computing nodes that can independently handle different gaming sessions. Each edge node serves local users, allowing simultaneous support for multiple sessions across different geographic locations without requiring all sessions to consume bandwidth from a single centralized source.
Solution Approach 2:
The patent implements local quality by deploying rendering services at network edges close to users. Each edge node provides localized game rendering with optimized bandwidth usage for its specific region, allowing multiple sessions to be supported simultaneously with each session using only the bandwidth necessary for its local user base.
3Ease of operation
If game rendering is performed remotely in cloud gaming, then hardware requirements at client devices are reduced, but network latency increases and affects gameplay quality
Solution Approach 1:
The patent introduces edge computing nodes at network perimeters and mobile network edges, creating intermediate rendering locations between centralized datacenters and end users. This spatial repositioning reduces the network distance dimension, thereby reducing latency while still allowing lightweight client devices to be used.
Solution Approach 2:
The patent introduces edge computing nodes as intermediary elements between centralized game servers and end user devices. These intermediaries perform local game rendering and streaming, reducing the direct network distance between users and rendering services, thereby reducing latency while maintaining the cloud gaming model that allows lightweight client devices.
4Reliability
If cloud gaming infrastructure is deployed to improve service quality, then rendering performance is improved, but device complexity and infrastructure cost increase
Solution Approach 1:
The patent makes existing network infrastructure elements (content delivery networks, mobile network edges) serve dual purposes: their original functions plus game rendering services. This multi-functionality allows cloud gaming infrastructure to be built upon existing deployed networks rather than requiring entirely new specialized infrastructure, reducing overall system complexity.
Solution Approach 2:
The patent enables existing network edge infrastructure to self-serve by providing game rendering capabilities without requiring completely new dedicated gaming infrastructure. The same network edges that deliver content also deliver game rendering services, allowing the infrastructure to serve multiple purposes and reducing the complexity of deploying separate gaming-specific infrastructure.
