Network Resource Abstraction for 5G Mobility Orchestration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G wireless communications networks face challenges in managing mobility and heterogeneity across radio, transport, and computing domains, particularly in providing services that require seamless connectivity across geographical areas as users move, with existing solutions failing to adequately account for end-user mobility and resource allocation.
Innovation Solution
A method and apparatus that abstract network resources by introducing a coverage area parameter in service descriptions, allowing for the identification and management of abstracted resources from radio, transport, and computing domains, enabling efficient orchestration and decoupling of domains to support mobility and service isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network resources are managed without abstraction across radio, transport, and computing domains, then resource allocation can be directly controlled, but the system complexity increases and mobility support becomes difficult
Solution Approach 1:
The patent segments network resources into three distinct abstracted domains: radio domain resources (cell coverage areas), transport domain resources (network connectivity), and computing domain resources (processing capabilities). This segmentation allows independent management of each domain while supporting mobility through the coverage area parameter that tracks user equipment across domain boundaries.
Solution Approach 2:
The patent introduces an intermediary orchestration layer that manages abstracted resources from multiple domains. This intermediary translates high-level service requirements into domain-specific resource allocations, reducing orchestration complexity by hiding the intricate details of cross-domain resource management while maintaining mobility support through coverage area tracking.
2Productivity
If services are provided without considering geographical coverage areas, then service deployment is simplified, but end-user mobility cannot be supported
Solution Approach 1:
The patent adds a geographical coverage area dimension to service deployment by introducing the coverage area parameter that defines spatial boundaries for service delivery. This dimensional addition enables the system to track and support mobile users across different locations while maintaining efficient service delivery within defined coverage areas through the abstracted resource model.
3Adaptability or versatility
If network resources are tightly coupled across domains, then resource allocation is straightforward, but flexibility and scalability are reduced
Solution Approach 1:
The patent segments tightly coupled network resources into independent abstracted domains (radio, transport, computing), each with its own resource characteristics and management rules. This segmentation provides service flexibility by allowing independent optimization of each domain while the orchestration layer coordinates them, maintaining resource allocation simplicity through standardized abstracted interfaces.
Solution Approach 2:
The patent creates a universal abstracted resource model that can represent diverse resources from different domains through common parameters and structures. This universal model enables flexible service deployment across multiple domains while maintaining allocation simplicity through a standardized interface that handles domain-specific complexities internally.
4Extent of automation
If service creation and activation are manual processes, then control is precise, but automation level and cost efficiency decrease
Solution Approach 1:
The patent enables self-service automation by allowing the orchestration system to automatically discover, allocate, and manage abstracted resources from multiple domains based on service requirements. The system autonomously handles resource provisioning and updates without manual intervention, achieving high automation levels while managing complexity through the simplified abstracted resource model that presents a uniform interface for resource management.

AI summary
A method of orchestrating a plurality of network resources for providing a requested network service in a mobile communications network. The method comprises monitoring service requests (202) and obtaining information comprising abstracted resources of radio domain, transport domain and computing domain (206). The method also comprises obtaining and processing a service description comprising a set of parameters defining the service to be provided (208) and identifying in the abstracted resources from the radio domain, transport domain and computing domain resources for delivering the service defined in the service description in a coverage area determined based on the service description (212).
