Abstract: Embodiments of the present invention provide a method for improving voice call quality. The method is applied to a terminal, and the terminal includes a buffer module. When the buffer module includes voice data, the method includes: determining that the voice data buffered by the buffer module is in an accumulated state; and cutting off an SID frame in the voice data. To be specific, when the SID frame is detected and the voice data buffered by the buffer module is in the accumulated state, the SID frame in the voice data is cut off. The SID frame does not include semantic data. In this way, an amount of to-be-sent voice data is reduced, a packet loss and a sending delay are reduced, voice call quality is improved, and user experience is improved.

Abstract: A transmission control method in a satellite communication system and a related apparatus are provided. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one satellite in geosynchronous orbit. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite and may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data and attitude data of the terminal. The terminal may enable, by using the satellite transmission link direction and the radiation direction of the satellite antenna, the radiation direction of the satellite antenna in the terminal to be aligned with the target satellite. After aligning with the target satellite, the terminal may send a first data packet to the target satellite along the radiation direction of the satellite antenna.

Abstract: A letter download query method may include a terminal sending a letter download query request packet to a satellite network device, where the letter download query request packet includes a service type field and a message ID field, the service type field indicates a service type of the letter download query request packet, and the message ID field indicates an ID of a letter successfully received by the terminal last time. The terminal receives a letter download query result packet from the satellite network device, where the letter download query result packet includes an original letter sending time field and a letter content field, the original letter sending time field indicates original sending time of letter content in the letter content field, and the letter content field indicates letter content from one or more target terminals to the terminal.
