1Productivity
If wireless terminals use traditional network slicing without area scope-based mapping configurations, then the network structure remains simple, but resource selection efficiency and service quality optimization are insufficient
Solution Approach 1:
The patent segments network slice configurations by introducing area scope-based mapping configurations. Each mapping configuration is associated with a specific area scope (registration area, tracking area, or cell level), allowing the network to divide and manage slice resources according to spatial distribution. This segmentation enables efficient resource selection by matching terminal location with appropriate network slice configurations.
Solution Approach 2:
The patent implements dynamic configuration where mapping configurations can be activated or deactivated based on terminal location and network conditions. The area scope parameter allows the system to dynamically adapt which mapping configuration applies to a terminal based on its current registration area, tracking area, or cell, optimizing resource selection in real-time.
2Reliability
If multiple mapping configurations with different area scopes are deployed, then service quality optimization improves, but terminal processing complexity increases
Solution Approach 1:
The patent applies local quality by associating different mapping configurations with specific area scopes. Each configuration is optimized for its target area (registration area, tracking area, or cell level), allowing terminals to select the most appropriate configuration based on their local location. This ensures service quality optimization without requiring terminals to process all configurations uniformly.
Solution Approach 2:
The terminal autonomously determines which mapping configuration to apply by evaluating its current location against the area scope parameters. The terminal self-selects the appropriate configuration without requiring complex network-controlled decision-making, reducing terminal processing complexity while maintaining service quality optimization.
3Productivity
If network operators configure multiple area scopes for mapping configurations, then resource allocation optimization improves, but configuration management difficulty increases
Solution Approach 1:
The patent segments configuration management by introducing area scope as a hierarchical parameter. Operators can configure mapping configurations at different levels (registration area, tracking area, cell) independently, making it easier to manage and deploy configurations across the network. This segmentation allows targeted optimization without requiring complete network reconfiguration.
Solution Approach 2:
The area scope parameter serves multiple functions: it defines spatial validity, enables hierarchical configuration management, and facilitates resource allocation optimization. This multi-functionality reduces the need for separate configuration mechanisms, simplifying overall configuration management while maintaining resource allocation optimization capabilities.
