Dynamic Network Slice Release for Background Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks with network slicing, users are charged higher fees due to time-based charging policies even when applications are in background or unused, leading to adverse user experience and unnecessary power consumption.
Innovation Solution
A terminal device acquires operation information to determine and release unnecessary network slices, switching applications to a default network to avoid time-based charges and conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If applications maintain connection to network slices in background mode, then network service availability is preserved, but charging costs and power consumption increase
Solution Approach 1:
The patent implements dynamic network slice management by monitoring application states and adjusting network slice connections in real-time. When applications enter background mode, the system dynamically releases their network slice connections, while maintaining connections for foreground applications. This dynamic adaptation resolves the contradiction by making the connection state flexible rather than static, reducing power consumption while preserving service availability when needed.
2Reliability
If applications maintain connection to network slices in background mode, then network service availability is preserved, but charging costs increase
Solution Approach 1:
The system dynamically manages network slice connections based on application states. By monitoring whether applications are in foreground or background modes, the system selectively maintains or releases connections. This dynamic approach ensures network service availability for active applications while avoiding charging costs for inactive background applications, resolving the contradiction between reliability and cost.
3Use of energy by moving object
If network slices are released for background applications, then charging costs and power consumption are reduced, but network service availability may be compromised
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors application states (foreground/background modes) and uses this information to control network slice connections. When an application enters background mode, the system receives feedback and releases the network slice connection. When the application returns to foreground, the connection is restored. This feedback-based control ensures that network service availability is preserved when needed while reducing power consumption when applications are inactive.
4Duration of action of stationary object
If network slice connections are maintained for all applications, then service continuity is ensured, but system resources are wasted
Solution Approach 1:
The patent extracts and removes network slice connections from applications that no longer need them (background mode applications). By selectively taking out unnecessary connections while maintaining essential ones for foreground applications, the system ensures service continuity for active applications while eliminating waste of system resources on inactive applications. This extraction principle resolves the contradiction between service continuity and resource efficiency.
