Dynamic Network Slice Activation via Context Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network slicing technologies cannot automatically and dynamically adapt to unpredictable changes in user situations, leading to inefficient resource allocation and service provision.
Innovation Solution
A method for activating or deactivating network slices based on acquired context data, such as geolocation or user activity, to optimize resource usage and adapt network services in real-time, allowing for dynamic and personalized network configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slices are allocated to services in advance (static 5G slicing), then service requirements are met, but network resources are reserved and unused when services are not being used
Solution Approach 1:
The patent implements dynamic network slicing where slices are activated and deactivated based on real-time service requirements. The network management device monitors service status and dynamically adjusts slice allocation, transitioning from static pre-allocation to dynamic on-demand allocation. This resolves the contradiction by making resource allocation adaptive - services receive guaranteed resources when needed (maintaining reliability) while resources are released when not in use (reducing waste).
Solution Approach 2:
The system changes the parameter of slice allocation from fixed/static to variable/dynamic. By introducing time-varying allocation parameters based on service activation status, the system optimizes resource utilization while maintaining service quality requirements. The allocation parameters are adjusted according to actual service demand rather than remaining constant.
2Productivity
If network slices are dynamically adapted to user situations, then resource allocation efficiency is improved, but system complexity increases due to real-time monitoring and decision-making requirements
Solution Approach 1:
The terminal device is empowered with autonomous capabilities to detect its own service requirements and trigger slice activation/deactivation. The terminal monitors its own operational state and communicates with the network management device to request slice operations. This self-service approach reduces the burden on the network side while maintaining dynamic adaptability, resolving the complexity issue by distributing intelligence to the edge.
Solution Approach 2:
The system implements feedback loops where terminal devices report their service status to the network management device, which then adjusts slice allocation accordingly. This closed-loop control enables automatic adaptation to changing conditions without requiring complex centralized decision-making for every scenario. The feedback mechanism allows the system to respond to user situations dynamically while keeping the control architecture manageable.

AI summary
A method for activation or deactivation, for a terminal, of a virtual subset of a telecommunications network referred to as a “network slice”, dedicated to a service. The telecommunications network includes a plurality of network slices. The method includes: acquiring at least one piece of context data of a user; and activating or deactivating at least one network slice among the plurality of network slices on the basis of the previously acquired piece of context data.
