Base Station Selection by Connection Time in Non-Terrestrial Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-ground networks, the short connection time of non-transparent satellite base stations moving relative to the ground causes frequent cell switching during multi-connection processes, affecting transmission quality.
Innovation Solution
Selecting a primary and secondary base station based on estimated connection times to minimize cell switching and improve transmission quality by choosing base stations with longer connection times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple connections are established in non-ground networks, then data transmission rate is improved, but cell switching frequency increases due to short connection times
Solution Approach 1:
The patent applies preliminary action by predicting the connection time between the user device and candidate base stations before establishing multi-connection. The network device obtains location information and predicts connection durations, then selects base stations with sufficiently long connection times to avoid frequent switching during the data transmission process
Solution Approach 2:
The patent implements dynamics by continuously updating the connection time predictions as the user device and base stations move relative to each other. The system dynamically adjusts the selection of primary and secondary base stations based on real-time location information and predicted connection durations, ensuring stable connections throughout the transmission process
2Reliability
If base stations with longer connection times are selected, then cell switching frequency is reduced, but the selection criteria and complexity increase
Solution Approach 1:
The patent applies self-service by enabling the network device to autonomously perform base station selection based on automated prediction algorithms. The system automatically obtains location information, predicts connection times, and selects appropriate base stations without requiring manual intervention or complex external coordination
Solution Approach 2:
The patent replaces mechanical selection processes with computational methods. Instead of manual or heuristic base station selection, the system uses algorithmic prediction of connection times based on location data, substituting complex mechanical decision-making with automated computational analysis

AI summary
Provided are an electronic device, a method for wireless communication, and a computer-readable storage medium. The electronic device may comprise a processing circuit, and the processing circuit is configured to: select, on the basis of estimated connection times with respect to candidate primary base stations and candidate secondary base stations, a primary base station and a secondary base station that are suitable for serving a user equipment, wherein the candidate primary base stations and the candidate secondary base stations comprise at least one non-transparent satellite base station which moves relative to the ground. According to at least one aspect of the embodiments of the present disclosure, a primary base station and a secondary base station that are suitable for serving a user equipment in a non-terrestrial network are selected on the basis of estimated connection times with respect to candidate primary base stations and candidate secondary base stations, so as to avoid, to the greatest possible extent, the transmission quality from being affected by a connection time of a non-terrestrial satellite base station, which moves relative to the ground, being too short.
