NFV Orchestration with Terminal Location Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network functions virtualization management and orchestration (NFV-MANO) systems lack the ability to perform optimal resource allocation based on terminal location, leading to suboptimal service delivery, particularly in scenarios like mobile edge computing where terminal movement affects service quality and compliance with service level agreements.
Innovation Solution
A network functions virtualization management and orchestration apparatus that includes multiple virtualized infrastructure managers (VIMs) to control virtual network functions on servers connected to base stations, a visiting information manager to track terminal location, and a VNF arrangement controller to dynamically rearrange services based on terminal location data, ensuring optimal resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal location tracking is implemented in NFV-MANO system, then service delivery quality is improved, but system complexity increases
Solution Approach 1:
The patent introduces a visiting information manager as an intermediary component that specifically handles terminal location tracking and management. This mediator separates the location tracking function from the core NFV-MANO system, allowing the main system to benefit from location-aware service delivery without directly承担 the complexity of location management. The visiting information manager acts as a buffer layer between the terminal mobility and the VNF arrangement controller.
Solution Approach 2:
The patent divides the NFV-MANO system into distinct functional modules: visiting information manager for location tracking, VNF manager for service management, and VNF arrangement controller for resource allocation. This segmentation allows each component to specialize in specific tasks, improving overall service delivery quality while distributing system complexity across multiple manageable components rather than concentrating it in one system.
2Speed
If dynamic VNF rearrangement is performed based on terminal location, then real-time performance is improved, but resource allocation overhead increases
Solution Approach 1:
The patent pre-establishes the visiting information manager and its location tracking capabilities before terminal movement occurs. By having the location tracking infrastructure ready in advance, the system can immediately respond to terminal location changes without incurring setup delays. The VNF arrangement controller is also pre-configured with the ability to perform rapid rearrangement based on location data, reducing the time overhead when actual movement detection occurs.
Solution Approach 2:
The patent implements a feedback mechanism where the visiting information manager continuously monitors terminal location and provides real-time location information to the VNF arrangement controller. This feedback loop enables the system to dynamically adjust VNF placement based on current terminal positions, improving real-time performance. The automated feedback-driven rearrangement process reduces manual intervention time and optimizes resource allocation efficiency.

AI summary
A network functions virtualization management and orchestration apparatus includes a plurality of VIMs, a visiting information manager, and a VNF arrangement controller. Each of the plurality of VIMs controls start and stop of a VNF in a virtual machine on each of servers connected to a plurality of respective base stations. The visiting information manager manages visiting information of each terminal wirelessly connecting to any of the base stations. The VNF arrangement controller controls arrangement of the VNF to provide services to the terminals, based on VIM management information and terminal visiting information, the VIM management information defining, for each VNF, a VIM capable of starting the VNF on each of the servers connected to the base stations.
