Wireless Communication Identifier Validation for NTN Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in large cells like Non-Territorial Networks (NTN), broadcast transmissions often reach unintended users, leading to resource wastage and unnecessary power consumption, as the system cannot accurately determine the validity of received messages, especially when the transmission area exceeds the deployment area.
Innovation Solution
A method where a first node determines a target identifier associated with access stratum information, allowing it to validate whether received non-access stratum information is valid by comparing it with a first identifier set, ensuring only intended users receive and process valid messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If broadcast transmission is used to reach multiple users in large cells, then coverage area is improved, but resource wastage increases due to unintended users receiving messages
Solution Approach 1:
The patent introduces an identifier validation mechanism as an intermediary between broadcast transmission and message processing. The first node uses a target identifier to validate whether received broadcast messages are intended for it, filtering out unintended messages before processing. This resolves the contradiction by maintaining wide broadcast coverage while preventing resource wastage through identifier-based filtering.
2Adaptability or versatility
If broadcast messages are transmitted to large coverage areas, then service flexibility is improved, but false alarms increase due to unrelated users receiving messages
Solution Approach 1:
The patent implements a feedback mechanism where the first node continuously validates received broadcast messages against its target identifier. This feedback loop allows the system to maintain flexible broadcast transmission while automatically detecting and discarding unintended messages, thereby preventing false alarms while preserving service flexibility.
3Stability of the object's composition
If all users in large cells receive broadcast messages, then system stability is maintained, but power consumption increases due to processing invalid messages
Solution Approach 1:
The patent applies preliminary action by performing identifier validation before full message processing. The first node checks whether the target identifier matches the broadcast message identifier upfront, discarding invalid messages before they consume significant processing power. This maintains system stability through consistent message handling while dramatically reducing power consumption by avoiding processing of invalid messages.

AI summary
The disclosure provides a method and a device for wireless communication. The method includes: determining a target identifier, and receiving a first signal, the first signal carrying first information; wherein the first information comprises information of an access stratum, the first information is used for indicating a first identifier set, and the first identifier set comprises a positive integer number of identifiers; the first identifier set is associated to second information; a second signal carries the second information, and the second information comprises information of a non-access stratum; whether the first identifier set comprises the target identifier is used for determining whether the second information is valid. The disclosure determines the validity of the second information through reasonably determining the target identifier and the first identifier set, thus increasing the reliability of the system and saving system resources.
