NTN Device Selection Mechanism for Satellite Communication Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of non-terrestrial networks (NTN), existing technologies face challenges in efficiently selecting the most appropriate NTN device for data transmission, particularly in scenarios where satellites have discontinuous connections with terminal devices and core networks, leading to potential delays and inefficiencies.
Innovation Solution
The proposed solution involves an apparatus and method that receive information from a non-terrestrial network device regarding a set of candidate NTN devices, including expected connection times with core network devices and memory usage information. This information is used to select the most suitable NTN device for data transmission, thereby minimizing latency and optimizing network performance.

Engineering Contradiction Analysis
1Reliability
If a satellite provides service to terminal devices during periods without simultaneous connection to core network, then service availability is improved, but transmission delay increases
Solution Approach 1:
The patent applies preliminary action by having the terminal device obtain information about multiple candidate NTN devices and their expected connection times to the core network in advance. This allows the device to proactively select the optimal NTN device that will connect to the core network soonest, thereby minimizing transmission delay while maintaining service availability during discontinuous connections
2Reliability
If multiple candidate NTN devices are monitored, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies the taking out principle by extracting only the essential information needed for selection from multiple candidate NTN devices - specifically, the expected connection time to core network and memory usage information. The terminal device uses this extracted information to identify and select the single optimal NTN device, achieving reliable transmission without the complexity of continuously monitoring and managing all candidate devices in detail

AI summary
The present disclosure relates to selecting a NTN device. In particular, a NTN device transmits information related to a set of NTN devices to a terminal device. The terminal device selects a NTN device from the set of NTN devices based on the information. The terminal device transmits data to the selected NTN device. In this way, it can avoid long latency.
