Cell Configuration Determination for NTN Regulatory Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Non-Territorial Network (NTN) systems, determining the appropriate cell configuration for a terminal's location is challenging due to varying frequency regulations across regions, which can lead to compliance issues and inefficient cell access.
Innovation Solution
A method and apparatus for determining cell configuration, where a terminal receives area information and corresponding cell configuration information based on its position, allowing it to identify the target area and applicable cell configuration, and a base station broadcasts area and cell configuration information to enable terminals to determine the correct configuration for compliance and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a terminal uses a single cell configuration for all areas, then the device complexity is reduced, but the reliability of compliance with local regulations deteriorates
Solution Approach 1:
The patent divides the service area into multiple geographic regions, each with its own cell configuration information. The terminal receives and stores multiple cell configuration sets corresponding to different areas, and selects the appropriate configuration based on the current location. This segmentation allows different regions to have different frequency and access control settings, ensuring regulatory compliance without requiring a single complex universal configuration system.
Solution Approach 2:
The patent implements location-specific cell configuration information that adapts to local regulatory requirements. Each geographic area has customized configuration parameters including frequency bands and access control settings that match local regulations. The terminal determines its location and applies the corresponding local configuration, ensuring that each region receives appropriate local-quality service settings rather than a uniform global configuration.
2Reliability
If the base station broadcasts detailed area and cell configuration information to all terminals, then the reliability of cell access compliance is improved, but the loss of information increases due to redundant data transmission
Solution Approach 1:
The base station pre-configures and broadcasts cell configuration information for multiple areas before the terminal needs to access any specific cell. The area information and corresponding cell configuration information are prepared in advance and made available to terminals. This preliminary action ensures that when a terminal needs to access a cell, the required configuration information is already available, improving compliance reliability without requiring real-time information transmission for each access decision.
Solution Approach 2:
The patent uses area information as a reference copy that describes geographic regions, and cell configuration information as corresponding data copies that provide specific settings for each area. Instead of transmitting complete configuration data for every possible scenario in real-time, the system broadcasts structured area and configuration information that terminals can reference and copy as needed, reducing redundant information transmission while maintaining compliance reliability.
3Productivity
If the terminal determines cell configuration based on precise location information, then the productivity of cell access is improved, but the measurement precision requirements increase
Solution Approach 1:
The patent implements cell configuration determination using partial location information rather than requiring complete precise location data. The terminal determines its location to a sufficient degree to identify the relevant geographic area and select the appropriate cell configuration. This partial action approach achieves adequate cell access efficiency without demanding excessive measurement precision, allowing terminals to operate effectively with reasonable location accuracy rather than requiring high-precision positioning systems.
