Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Background Data Transfer (BDT) mechanisms in telecommunication networks lack efficient mechanisms for adapting to network performance changes, leading to suboptimal data transfer policies and increased costs for users and service providers.
Innovation Solution
A method for managing BDT that involves network elements like Policy Control Function (PCF), Network Exposure Function (NEF), and Network Data Analytics Function (NWDAF) to monitor and adapt BDT policies based on network performance recovery and degradation notifications, allowing for dynamic selection of BDT policies that optimize data transfer during different time windows and locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BDT policies are set statically without monitoring network performance changes, then the system complexity is reduced, but the adaptability to network conditions deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where network elements (PCF, NEF, NWDAF) continuously monitor network performance and send notifications about degradation or recovery events. This feedback loop enables the system to automatically detect network condition changes and trigger BDT policy adjustments, resolving the contradiction between adaptability and complexity by making the system responsive without requiring constant manual reconfiguration
Solution Approach 2:
The patent transitions from static BDT policies to dynamic policies that can change based on network performance conditions. The system dynamically selects and updates BDT policies in response to network degradation or recovery notifications, allowing the data transfer characteristics to adapt automatically to current network state while maintaining manageable complexity through automated decision-making
2Productivity
If BDT policies are not adapted to network performance changes, then the implementation simplicity is maintained, but the data transfer efficiency deteriorates
Solution Approach 1:
The patent enables the network system to self-adjust BDT policies based on automated monitoring and notification mechanisms. The PCF, NEF, and NWDAF work together to detect network conditions and autonomously update policies without requiring external intervention, thereby improving data transfer efficiency while keeping the implementation complexity manageable through standardized self-service procedures
Solution Approach 2:
The system performs preliminary actions by establishing monitoring mechanisms in advance and preparing BDT policy update procedures before network performance changes occur. When degradation or recovery is detected, the system can quickly execute pre-prepared policy adjustments, improving responsiveness and data transfer efficiency without requiring complex real-time decision-making processes
3Loss of energy
If network performance monitoring is not implemented, then the operational simplicity is maintained, but the ability to optimize data transfer costs deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where network elements monitor performance metrics and send notifications about degradation or recovery events. This enables the system to identify optimal times for data transfer based on actual network conditions, reducing data transfer costs by avoiding peak congestion periods while maintaining acceptable monitoring complexity through standardized notification protocols
Solution Approach 2:
The system optimizes data transfer costs by dynamically changing BDT policy parameters (such as allowed data types, transfer timing, and quality of service levels) based on monitored network performance parameters. When network conditions indicate lower costs or better availability, the system automatically adjusts transfer parameters to exploit these favorable conditions, reducing overall data transfer expenses
