Solution Overview
Problem
Intelligent terminal devices face challenges in maintaining satellite alignment during satellite communication, leading to potential call interruptions due to limited antenna space and high path loss, which affects user experience.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite communication is implemented in intelligent terminal devices, then communication range and reliability are improved, but antenna space is limited and path loss is large, resulting in a tight link budget
Solution Approach 1:
The patent applies dynamics by making the call interface dynamically adjustable based on terminal orientation. The interface can switch between a first interface (when the terminal is in satellite-alignment attitude) and a second interface (when the terminal is not in satellite-alignment attitude), allowing the system to adapt to changing spatial conditions while maintaining reliable communication.
Solution Approach 2:
The patent changes interface parameters (display content, layout, or characteristics) based on the terminal's alignment status with the satellite. When alignment deviates from the preset range, the system modifies the call interface parameters to prompt users to adjust the terminal orientation, thereby optimizing the link budget under constrained antenna space.
2Duration of action of stationary object
If the terminal device maintains satellite-alignment attitude, then service continuity is maintained, but the user experience is degraded due to restricted device orientation
Solution Approach 1:
The patent implements feedback by monitoring the terminal's orientation relative to the satellite and providing real-time visual feedback through the call interface. When the terminal deviates from the satellite-alignment attitude, the interface changes to display prompts or warnings, guiding users to adjust the orientation while maintaining service continuity.
Solution Approach 2:
The call interface is designed to be dynamic, automatically adapting its display characteristics based on the terminal's alignment status. This dynamic adjustment provides users with clear guidance on maintaining proper orientation without requiring them to understand complex technical parameters, thus preserving ease of operation.
3Reliability
If the call interface displays prompt information about alignment deviation, then call interruption is prevented, but the interface complexity increases
Solution Approach 1:
The patent applies local quality by adding prompt information only in the specific local condition when alignment deviation occurs. The call interface maintains its standard simple design under normal conditions, and only introduces additional prompt elements locally when the terminal deviates from the satellite-alignment attitude, thus preventing call interruption without permanently increasing interface complexity.
Solution Approach 2:
The interface complexity is dynamically adjusted based on alignment status. When properly aligned, the interface remains simple and clean. When deviation occurs, prompt information is dynamically added to guide users, and then removed when alignment is restored, maintaining overall interface simplicity while ensuring call continuity.

AI summary
Embodiments of this application provide a satellite call method and a terminal device. The method includes: making a satellite call and displaying a call interface based on communication with a first satellite; determining an azimuth angle deviation and a pitch angle deviation, and the satellite transmission link direction is a direction from a position of the terminal device to a position of the first satellite; and displaying prompt information on the call interface if the azimuth angle deviation and the pitch angle deviation satisfy a preset condition, where the prompt information prompts a user that there is a possibility that a call on the terminal device is interrupted. The method helps the user to adjust the position of the terminal device in a timely manner, to avoid call interruption, and improve user experience.
