Edge Service Relocation Using Resource Templates for 5G Multimedia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G multimedia edge services face challenges in relocating application servers seamlessly across different data networks due to user mobility, fault tolerance, and performance variations, necessitating methods for optimal service relocation with resource configuration and performance guarantees.
Innovation Solution
The implementation of a resource template structure for application service relocation, including network buffers for temporary media content storage, application service directories, and KPI guarantees, enables dynamic relocation of services to ensure uninterrupted performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If application services are deployed at edge data networks closer to end users, then service performance and responsiveness are improved, but service continuity and reliability deteriorate due to user mobility and network failures
Solution Approach 1:
The system performs preliminary actions by establishing service relocation capabilities in advance. When a UE moves between data networks or network failures occur, the application service can be proactively relocated to a target data network before service interruption occurs, ensuring continuous service delivery without affecting responsiveness
Solution Approach 2:
The system changes the deployment location parameter of application services dynamically. By relocating services from source data networks to target data networks based on UE mobility and network conditions, the system maintains both close proximity to users (for responsiveness) and service continuity (for reliability)
2Reliability
If application services are relocated to target data networks, then service continuity is improved, but resource configuration complexity increases
Solution Approach 1:
The system creates a copy of the application service from the source data network and deploys it to the target data network. This copying approach maintains service continuity while using standardized resource templates to manage configuration complexity, as the copied service inherits the resource requirements defined in the template
Solution Approach 2:
The system uses universal resource templates that can be applied across different data networks. These templates define standardized resource requirements (compute, storage, networking) that make the relocation process systematic and manageable, reducing the complexity of configuring services in different network environments
3Manufacturing precision
If resource templates with KPI guarantees are implemented, then service performance is improved, but system complexity increases
Solution Approach 1:
The system changes the resource allocation parameters dynamically based on KPI requirements. By defining specific performance metrics (latency, throughput, reliability) in resource templates and adjusting resource allocation to meet these parameters, the system ensures service performance quality while managing complexity through standardized template-based configuration

AI summary
An apparatus includes a includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives signaling that indicates edge application service relocation for transferring a user equipment (UE) session for a UE to a target edge data network. The processor identifies an edge application service in the source edge data network processing media content corresponding to the UE session; generates a resource template for the edge application service including requirements for running the edge application service; transmits a request for the edge application service relocation to the target edge data network, the request including the resource template; and enables the edge application service relocation for the user equipment from the edge application service at the source edge data network to an edge application service at the target edge data network.
