Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in sliced networks face challenges in efficiently selecting and managing resources across different network slices, particularly in determining the validity of mapping configurations and area scope information for wireless terminals.
Innovation Solution
The implementation involves wireless terminals, access nodes, and management entities within a public land mobile network (PLMN) that utilize receiver and processor circuitry to receive and generate area identities and mapping configurations, associated with area scope information, to determine the validity of network slice groups and perform resource selection based on network slice band association information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If network slice groups are configured with area scope information to determine validity in specific cells, then resource selection accuracy is improved, but device complexity increases due to additional validity determination logic
Solution Approach 1:
The network pre-configures area scope information and validity conditions for mapping configurations before the wireless terminal operates. The terminal receives and stores these pre-defined area identities and scope parameters, then simply compares its current location against these pre-established criteria to determine validity, avoiding complex real-time calculations.
Solution Approach 2:
Different mapping configurations are assigned different area scope information tailored to their specific deployment requirements. Each configuration has localized validity parameters (area identities, scope types) that apply only to its designated geographic region, allowing optimized resource selection for each local network slice without affecting other areas.
2Reliability
If area scope information is included in mapping configuration to restrict validity areas, then service reliability is improved, but information processing overhead increases
Solution Approach 1:
The area scope information is extracted as a separate, standardized parameter set from the overall mapping configuration. By defining area identities, scope types, and validity conditions as distinct elements that can be independently processed and stored, the system reduces the cognitive load on the terminal and enables more efficient information management.
3Adaptability or versatility
If multiple area identities are transmitted to wireless terminal for validity determination, then network coverage flexibility is improved, but communication overhead increases
Solution Approach 1:
The area scope information structure is designed to be universal and multi-functional. The same data structure (area identity, scope type, validity condition) can represent various geographic configurations (single cell, multiple cells, tracking areas) and serves multiple purposes including validity determination, resource selection, and mobility management, reducing the need for separate signaling mechanisms.

AI summary
A wireless terminal served by a public land mobile network wireless terminal comprises receiver circuitry and processor circuitry. The receiver circuitry is configured to (1) receive, from a first cell, a mapping configuration configuring one or more network slice groups, each of the one or more network slice groups indicating grouping of one or more corresponding network slices, the mapping configuration being associated with area scope information, and (2) receive, from a second cell, at least one area identity. The processor circuitry is configured to determine, based on the area scope information and the at least one area identity, whether or not the mapping configuration is valid in the second cell. The area scope information indicates one or more areas in which the mapping configuration is valid.
