Federated Edge Application Service Discovery Through ECS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network systems lack effective methods for discovering and sharing application services across federated operators, limiting the ability of operators to provide seamless services to their subscribers due to the absence of edge node sharing support in conventional Edge Enabler Layer (EEL) functionalities.
Innovation Solution
The proposed method and system enhance the EEL by enabling Edge Node Sharing service support through an Edge Configuration Server (ECS) that facilitates subscription, notification, and information exchange between ECS repositories of different operators, allowing for efficient discovery and management of Edge Application Servers (EAS) across federated networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Edge Enabler Layer (EEL) functionalities are used, then basic edge service provisioning is supported, but edge node sharing and service discovery across federated operators are not enabled
Solution Approach 1:
The patent segments the service discovery functionality into separate network functions: ECS (Edge Configuration Server) for managing EAS (Edge Application Server) information, EES (Edge Enabler Server) for service discovery requests, and EEC (Edge Enabler Client) for client applications. This segmentation allows each component to have specialized responsibilities, enabling federated operator service sharing without overwhelming the base EEL functionality.
Solution Approach 2:
The patent introduces ECS as an intermediary component that mediates between multiple operators' EAS repositories. The ECS repository stores and manages EAS information from different operators, allowing EES of one operator to discover and access EAS of another operator through standardized interfaces, thus enabling federated service sharing.
2Reliability
If operators deploy edge services independently, then service security and control are maintained, but service sharing and continuity across networks are limited
Solution Approach 1:
The patent creates universal interfaces and data structures that work across different operators' networks. The EAS information model, subscription mechanisms, and notification protocols are designed to be operator-agnostic, allowing the same architecture to serve multiple operators while maintaining their individual service controls and security policies.
Solution Approach 2:
The patent implements feedback mechanisms through subscription and notification systems. When EAS information changes (addition, modification, removal), the ECS automatically notifies subscribed EES instances. This real-time feedback ensures service continuity by allowing clients to be promptly informed of service availability changes across federated networks.

AI summary
Embodiments herein disclose a method and system for discovering application services in federation of operators in a wireless network. The method performed by a first edge configuration server (ECS) repository of a first ECS, includes a registered edge application server (EAS) publish request or a registered EAS unpublish request from a first edge enabler server (EES), authorizing the registered EAS publish request or the registered EAS unpublish request upon receiving the registered EAS publish request or the registered EAS unpublish request from the first EES, sending a registered EAS publish response or a registered EAS unpublish response to the first EES when the registered EAS publish request or the registered EAS unpublish request is authorized.
