摘要： An outbound transmission control method in a BeiDou communication system, a system, and a related apparatus are provided. In the method, a BeiDou network device segments an application layer packet into a plurality of MDCP PDUs at an MDCP layer. The BeiDou network device sequentially delivers the MDCP PDUs to an SLC layer as SLC SDUs at the SLC layer, and segments the SLC SDU into N SLC PDUs at the SLC layer. SLC PDUs of one or more users are obtained at a PHY layer from the SLC layer. The SLC PDUs of the one or more users are spliced together at the PHY layer to form outbound data of a physical slot with a fixed length. Finally, the BeiDou network device sends the outbound data to one or more terminals. According to the technical solutions provided in this application, the BeiDou network device can implement multiframe transmission, so that requirements of outbound data of different service types can be met, outbound resource configuration can be optimized, and outbound resource utilization can be improved.

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.

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.
