Cell Reselection Using Tracking-Area Slice Priorities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slicing technologies lack flexibility in deploying different network slices within a registration area, as cells in the same registration area uniformly support the same slice, limiting the deployment of differentiated services for different users and scenarios.
Innovation Solution
A cell reselection method that utilizes tracking areas as units, determining priorities based on supported network slices and performing cell reselection according to these priorities, allowing different slices to be deployed within a registration area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cells in the same registration area uniformly support the same network slice, then the network deployment is simplified, but the flexibility of deploying different network slices for different users and scenarios is limited
Solution Approach 1:
The patent segments the registration area into multiple tracking areas, where each tracking area can independently configure and support different network slices. This segmentation allows different network slices to be deployed within the same registration area, enabling differentiated services for different users and scenarios while maintaining manageable network configuration through hierarchical area division.
2Adaptability or versatility
If network slices are deployed at the registration area level, then the configuration is simplified, but the ability to provide differentiated services for different users and scenarios is reduced
Solution Approach 1:
The patent applies local quality by allowing different tracking areas within a registration area to have different network slice configurations. Each tracking area can be independently configured to support specific network slices based on local requirements, enabling differentiated services for different users and scenarios while maintaining a hierarchical configuration structure that balances simplicity and flexibility.
3Productivity
If cell reselection does not consider network slice information, then the reselection process is simple, but the ability to select optimal cells for different network slices is lost
Solution Approach 1:
The patent introduces dynamics into cell reselection by making the reselection criteria adaptive based on network slice information. The terminal dynamically adjusts its cell reselection behavior according to the network slice configuration and requirements, enabling optimal cell selection for different network slices while maintaining efficient reselection through automated priority-based decision making.
