摘要： This application discloses a parameter update method in a BeiDou communication system, a system, and a related apparatus. The method includes: After a parameter in a BeiDou network device is updated, an updated parameter in the BeiDou network device may be sent to a cloud server. A terminal in a cellular network may obtain the updated parameter through the cloud server. Alternatively, when the terminal is in an environment without a cellular network, the terminal may obtain the updated parameter through a nearby BeiDou terminal. In this way, the terminal may update, in time, a related parameter that is of a BeiDou communication system and that is configured in the terminal.

摘要： This application relates to the field of satellite communication, and discloses an inbound transmission control method in a BeiDou communication system, a system, and a related apparatus. A terminal may send N SLC PDUs in a first SLC PDU to a BeiDou network device. If the BeiDou network device determines, based on frame header information of a received SLC PDU, that an SLC PDU in the first SLC SDU is missing, the BeiDou network device returns a first ACK to the terminal. The first ACK indicates a frame sequence number of an SLC PDU that is in the first SLC SDU and that is not received by the BeiDou network device. After receiving the first ACK from the BeiDou network device, the terminal retransmits, to the BeiDou network device, the SLC PDU that is in the first SLC SDU and that is not received by the BeiDou network device. In this way, when data sent by the terminal is lost, a normal data transmission process is ensured.

摘要： This application discloses a transmission control method in a satellite communication system and a related apparatus. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one geosynchronous orbit satellite. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite. The terminal may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data, attitude data, and the like of the terminal. Then, 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. In this way, without relying on an external component, a user can align the radiation direction of the satellite antenna in the terminal with the target satellite, to enhance communication performance between the terminal and the target satellite, and simplify satellite selection and satellite alignment operations performed by the user.

摘要： This application discloses a letter download query method in a BeiDou communication system, a system, and a related apparatus. The method may include: A terminal may send a letter download query request packet to a BeiDou 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 sent by the BeiDou 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 sent by one or more target terminals to the terminal. In this way, a user may receive, in a BeiDou network, a letter sent by a user in another cellular network.

摘要： Embodiments of this application are applicable to the field of communication technologies, and provide a Wi-Fi hotspot switching method, a terminal device, and a storage medium, and are applied to a system including a first terminal device and at least one second terminal device. The first terminal device enables a first Wi-Fi hotspot, and each second terminal device is connected to the first Wi-Fi hotspot. The first terminal device obtains mobile channel quality information and sharing capability information of each terminal device. When determining, based on the foregoing information, that the Wi-Fi hotspot needs to jump, the first terminal device sends first jump information to a target terminal device in the second terminal device, to indicate the target terminal device to enable a second Wi-Fi hotspot. After the first terminal device disables the first Wi-Fi hotspot and the target terminal device enables the second Wi-Fi hotspot, a device other than the target terminal device in the system may connect to the second Wi-Fi hotspot. Communication quality of the entire system is improved through automatic hotspot switching.
