Federated MEC Resource Discovery for Low-Latency Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network systems experience high latency due to remote cloud service providers being located far from end-users, leading to unpredictable and increased data transmission delays.
Innovation Solution
Implementing Multi-Access Edge Computing (MEC) resources at the edge of the wireless network to offload cloud-based services closer to end-users, utilizing identity federation for authentication and coordinating access through network controllers and edge orchestrators to manage resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cloud-based services are hosted remotely, then service provider infrastructure is simplified, but application latency increases and data transmission delays become unpredictable
Solution Approach 1:
The patent segments the cloud service infrastructure by deploying MEC resources at multiple edge locations distributed across the network. This divides the centralized cloud into decentralized edge nodes, allowing services to be processed closer to users while maintaining infrastructure simplicity through standardized edge deployments
Solution Approach 2:
The patent introduces a spatial dimension to service delivery by placing MEC resources at the network edge rather than in a centralized cloud. This dimensional shift from centralized to distributed architecture reduces transmission distance and latency while maintaining service provider control
2Loss of time
If MEC resources are deployed at the network edge, then application latency is reduced, but device complexity and resource allocation management increase
Solution Approach 1:
The patent introduces network controllers and edge orchestrators as intermediary components that manage MEC resource allocation. These intermediaries handle the complexity of coordinating distributed edge resources, allowing individual MEC nodes to remain simple while achieving sophisticated resource management across the network
Solution Approach 2:
The patent implements service offloading mechanisms that preliminarily prepare resource allocation by identifying suitable MEC resources before user requests arrive. This advance preparation reduces the real-time complexity of resource management while maintaining low latency performance
3Adaptability or versatility
If identity federation is used for authentication, then access coordination between services is improved, but authentication complexity increases
Solution Approach 1:
The patent implements a universal identity federation framework that enables a single authentication mechanism to work across multiple services and network operators. This universal approach allows the same authentication infrastructure to serve diverse access coordination needs, reducing overall complexity while maintaining versatility
Data Source
AI summary
Federated multi-access edge computing availability notifications may be provided by: transmitting, from a User Equipment (UE) to a node of a wireless network of a federated service, an attach request for the wireless network that includes authentication credentials for an independent identity provider in an identity federation, wherein the independent identity provider is external and independent from the wireless network and used to authenticate the UE to the wireless network; forwarding, from the node to the independent identity provider, the authentication credentials; transmitting, from the independent identity provider to the node, an authentication success message; receiving, at the UE via the node, the authentication success message; transmitting, from the UE to the node, a Multi-access Edge Computing (MEC) query; and receiving, at the UE from the node, a MEC response that identifies MEC resources that are available to the UE.
