Solution Overview

Problem

Existing edge computing systems face challenges in efficiently discovering and routing services due to decentralized deployment, leading to inconsistent latency and performance across different service instances, which conventional DNS mechanisms struggle to address.

Innovation Solution

Implementing a novel DNS architecture for edge computing that optimizes service discovery by utilizing edge network management (ENM) servers, which include client discovery, address assignment, and filtering mechanisms to ensure low latency and efficient service routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional DNS mechanisms are used for service discovery in edge computing, then service deployment flexibility is improved, but service discovery latency and performance consistency deteriorate

Engineering Contradiction:
Improveservice deployment flexibilityVSAvoidservice discovery latency
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces a specialized edge DNS server as an intermediary component that mediates between clients and edge services. This intermediary optimizes the service discovery process by maintaining local service registry information and providing direct resolution for edge services, thereby reducing discovery latency while preserving the flexibility of decentralized service deployment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the DNS resolution process into multiple stages: local edge DNS resolution for edge services, and conventional DNS resolution for non-edge services. This segmentation allows edge services to be resolved through optimized local pathways while maintaining overall system flexibility and adaptability.

Inventive Principle:
Principle #1Segmentation

2Speed

If services are deployed in a decentralized way at edge networks, then network latency is reduced, but service discovery complexity increases

Engineering Contradiction:
Improvenetwork latencyVSAvoidservice discovery complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent implements a universal edge DNS server that handles multiple functions: conventional DNS resolution, edge service discovery, and service registry management. This multi-functional approach simplifies the overall service discovery mechanism while maintaining low latency benefits of decentralized deployment.

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

Solution Approach 2:

The edge DNS server automatically discovers and registers edge services without requiring complex manual configuration. Services self-register with the edge DNS server upon deployment, and the server autonomously maintains the service registry, reducing discovery complexity while preserving decentralized deployment advantages.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If conventional DNS architecture is used, then implementation simplicity is maintained, but service routing efficiency to proximal servers deteriorates

Engineering Contradiction:
Improveimplementation simplicityVSAvoidservice routing efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent implements local quality optimization by deploying edge DNS servers at network edges close to service consumers. These local servers provide optimized routing to proximal edge services, improving service routing efficiency while maintaining implementation simplicity through standardized DNS protocols and familiar architecture patterns.

Inventive Principle:
Principle #3Local quality

AI summary

Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing discovery of edge computing servers are provided. A WTRU may send a request message, such as a protocol data unit (PDU) session establishment request, to the core network. The request may include (e.g., in a protocol configuration option (PCO)) information related to receiving edge data network configuration server (ECS) addresses. The WTRU may receive an acknowledgement or accept message (e.g., a PDU session establishment accept message) including (e.g., in another PCO) server information (e.g., ECS information) indicating addresses, identifiers, and/or tracking area identities (TAIs) that can be served by an associated ECS. The WTRU may perform communications with one or more ECSs.
