Dynamic Network Function Execution for Seamless Service Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network systems fail to provide consistent network-wide service experiences for users as network functions are fixed and not adaptable, leading to service disruptions when users move between nodes with differing capabilities.
Innovation Solution
A method and apparatus that allow network functions to be dynamically updated by receiving and running required network functions on target nodes, including downloading necessary modules and uninstalling them when the user service switches to another node, ensuring consistent service quality across different nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network functions are fixed and not updated after device sale, then device complexity is reduced and ease of manufacture is improved, but adaptability deteriorates and consistent network-wide service experience cannot be provided
Solution Approach 1:
The patent implements dynamic network functions by allowing target nodes to download and execute network function modules from a server based on real-time service requirements. This transforms static, fixed network functions into dynamic, adaptable ones that can change according to user service needs while maintaining manageable system complexity through centralized control.
Solution Approach 2:
The patent segments network functions into independent downloadable modules that can be selectively deployed on target nodes. This modular approach allows the system to provide adaptability by combining different function modules as needed, while keeping individual node complexity low since not all functions are permanently installed on each node.
2Reliability
If network functions are dynamically updated and downloaded on target nodes, then adaptability is improved and consistent service experience is achieved, but device complexity increases and loss of time occurs during module downloading
Solution Approach 1:
The patent applies preliminary action by pre-storing network function modules on a centralized server before they are needed. When a user service requires specific network functions, the target node can quickly download pre-prepared modules rather than generating them on-demand, significantly reducing the time loss associated with dynamic function deployment.
Solution Approach 2:
The patent introduces a server as an intermediary between the control node and target nodes. This intermediary pre-hosts network function modules and manages their distribution, allowing rapid deployment to multiple target nodes simultaneously and reducing the overall time required to achieve consistent service quality across the network.
3Adaptability or versatility
If network functions are dynamically deployed on target nodes, then adaptability is improved, but device complexity increases due to module management
Solution Approach 1:
The patent uses a centralized server as an intermediary to manage network function modules, handling storage, version control, and distribution. This externalizes the complexity of module management from individual target nodes to a dedicated server, allowing target nodes to maintain simplicity while the system as a whole achieves high adaptability through centralized coordination.
Solution Approach 2:
The patent creates a universal module management system where a single server handles multiple functions: storing modules, responding to download requests, managing versions, and coordinating deployments across numerous target nodes. This universal approach consolidates complexity into one multi-functional component rather than distributing it across many nodes.
