ATG Cell Access Indication for ATG and NTN Terminal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to effectively indicate whether an air to ground (ATG) terminal is allowed to access a cell, particularly when the cell is an ATG or non-terrestrial network (NTN) cell, due to identical access indications for multiple terminals.
Innovation Solution
The method involves receiving first information from a cell that indicates its type, allowing the ATG terminal to determine if access is permitted based on parameters such as cellBarredNTN and indication information, thereby personalizing access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same access indication is used for all terminals, then the system structure is simple, but the ATG terminal cannot be effectively indicated whether access is allowed
Solution Approach 1:
The patent applies local quality by providing different access indication information for different terminal types. Specifically, the network device sends first indication information to ATG terminals and second indication information to other terminals, allowing each terminal type to receive tailored access control instructions based on their specific characteristics and requirements.
Solution Approach 2:
The access indication mechanism is segmented into separate information streams: first indication information for ATG terminals and second indication information for other terminals. This segmentation allows independent control and optimization of access policies for different terminal types without affecting the entire system.
2Reliability
If access control is personalized for ATG terminals, then access control accuracy is improved, but the information transmission overhead increases
Solution Approach 1:
The patent extracts the access control information specifically for ATG terminals from the general system information. By separating the first indication information dedicated to ATG terminals from other terminal information, the system provides precise access control while minimizing unnecessary information transmission to ATG terminals.
Solution Approach 2:
ATG terminals autonomously determine whether to access the cell based on the first indication information received from the network device. The terminal independently processes the access control instructions and makes access decisions without requiring continuous network intervention, reducing information overhead.
