EDN Resource Reservation for Low-Latency EAS Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of edge application servers (EAS) in edge data networks (EDN) often fails due to insufficient remaining resources, leading to high deployment failure rates and increased latency when the 'first come, first served' mechanism is used.
Innovation Solution
A method is provided where an edge computing service provider reserves resources in advance based on the requirements of application service providers, ensuring a network connection with user plane functions, and deploys the EAS in these reserved resources to reduce deployment failures and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a 'first come, first served' mechanism is used for EAS deployment, then resource allocation is simple and fast, but deployment failure rate increases due to insufficient remaining resources
Solution Approach 1:
The patent implements resource reservation in advance before EAS deployment. The ECSP management system receives requirement information from ASPs, sends requests to MANO to reserve resources in EDN, and only then proceeds with deployment. This preliminary resource securing action ensures that deployment does not fail due to insufficient resources, directly resolving the contradiction between fast allocation and high success rate.
2Reliability
If resources are reserved in advance for EAS deployment, then deployment success rate improves, but resource utilization may decrease due to long-term occupation
Solution Approach 1:
The patent introduces dynamic resource management with expiration times for reservations. The ECSP management system sets expiration times for reserved resources and releases them automatically when expired or when no longer needed. This dynamic adjustment allows resources to be reserved in advance for reliable deployment while ensuring they are released back to the pool for reuse, preventing long-term occupation and maintaining high utilization.
3Reliability
If remaining resources in EDN are insufficient, then deployment failure occurs, but increasing resource allocation complexity
Solution Approach 1:
The patent introduces the ECSP management system as an intermediary between ASPs and the EDN infrastructure. This intermediary handles the complexity of resource reservation, expiration management, and release automatically. The ECSP management system receives requirements from ASPs, coordinates with MANO for resource reservation, and manages the entire lifecycle of reserved resources, thereby ensuring deployment availability without exposing complexity to users or requiring manual intervention.

AI summary
This application relates to the field of wireless communication technologies, and provides an edge application method and an apparatus. The method includes: An ECSP management system receives requirement information of a reserved resource from an ASP, and requests, based on the requirement information of the reserved resource, a MANO to reserve the resource in an EDN at a corresponding location. Then, the ASP may deploy an EAS or the like in the reserved resource. A resource for deploying the EAS is reserved in the EDN in advance, so that a probability that the EAS fails to be deployed due to reasons such as insufficient remaining resources in the EDN can be reduced.
