Solution Overview

Problem

Existing network architectures face high latency due to remote cloud services, as cloud service providers are often located far from user equipment, leading to unpredictable and undesirable 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 to authenticate users and manage access to MEC resources, and establishing offload orchestration sessions between cloud service providers and MEC resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cloud services are hosted remotely, then service accessibility is improved, but transmission latency increases

Engineering Contradiction:
Improveservice accessibilityVSAvoidtransmission latency
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments cloud services into two parts: centralized cloud-based services for general functionality and distributed edge-based services for location-sensitive operations. By segmenting services and deploying them at edge locations closer to users, the system reduces transmission latency while maintaining broad accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by deploying MEC resources at edge locations near users to provide localized service execution. This allows services to be executed closer to the user's premises, reducing the distance data must travel and thereby reducing latency for location-sensitive services while maintaining cloud connectivity for other functions.

Inventive Principle:
Principle #3Local quality

2Loss of time

If MEC resources are deployed at network edge, then transmission latency is reduced, but network architecture complexity increases

Engineering Contradiction:
Improvetransmission latencyVSAvoidnetwork architecture complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary authentication and authorization framework that mediates between users, cloud service providers, and MEC resources. This intermediary layer handles identity federation, access control, and resource allocation, simplifying the overall architecture by centralizing management functions while enabling distributed MEC deployment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements universality through a multi-functional authentication and authorization framework that serves multiple purposes: user identification, service selection, access control, and resource allocation. This universal framework reduces architectural complexity by consolidating multiple functions into a single system rather than requiring separate mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If identity federation is used for authentication, then user access flexibility is improved, but authentication system complexity increases

Engineering Contradiction:
Improveuser access flexibilityVSAvoidauthentication system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple authentication functions into a unified identity federation framework that combines user identification, service authorization, and resource access control in a single system. This merging approach provides flexible user access across multiple services while reducing overall system complexity compared to having separate authentication mechanisms for each service.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses copying by creating virtual representations of user identities and authentication contexts that can be shared across different services and networks. Instead of requiring direct trust between all systems, the framework creates copyable authentication tokens that convey user identity and authorization information, enabling flexible access while simplifying the trust management architecture.

Inventive Principle:
Principle #26Copying

AI summary

Federated multi-access edge computing availability notifications may be provided by: transmitting, from a User Equipment (UE) to an Access Point (AP) of a wireless network, an attach request for the wireless network that includes authentication credentials for an identity provider independent from the wireless network to authenticate the UE to the wireless network; receiving, at the UE via the AP, an authentication success message for the wireless network from the independent identity provider; transmitting, from the UE to the AP, a Multi-access Edge Computing (MEC) query; and receiving, at the UE from the AP, a MEC response that identifies MEC resources that are available to the UE based on an identity for the UE confirmed by the identity provider to the wireless network.
