IT House found that on August 26, the patent for "Method and Device for Satellite Communication" applied by Huawei Technologies Co., Ltd. was authorized. The patent abstract shows that the method can reduce the energy consumption and communication complexity of terminal equipment on the premise of improving communication performance. The present application provides a method and apparatus for satellite communication, the method includes: a terminal device receives first indication information, where the first indication information is used to indicate a valid period of first parameter information, and the first parameter information includes the following At least one kind of information: first timing advance, parameter information of the first timing advance, first frequency offset pre-compensation, or parameter information of the first frequency offset pre-compensation; The first parameter information performs uplink communication with the satellite, and the terminal device can obtain the first timing advance, the parameter information of the first timing advance, the first frequency offset pre-compensation or the first frequency offset by receiving the first indication information. The valid period of parameter information such as partial pre-compensated parameter information, so that there is no need to monitor whether the parameter information is updated within the valid period, so that the energy consumption and communication complexity of the terminal device can be reduced on the premise of improving communication performance. In addition, Huawei has previously applied for a number of patents related to satellite communications, such as "satellite network routing methods, devices, equipment, systems, and readable storage media" patents, which can reduce the distance of inter-satellite link information transmission, save communication overhead, and improve The inter-satellite routing capability in the space-earth integrated network communication scenario; the patent for "a method and device for wireless communication" can reduce the indication overhead of parameters and improve the accuracy by expressing satellite parameters as reference values ​​and floating values. IT House has learned that Tianfeng International analyst Ming-Chi Kuo previously broke the news that Huawei's new Mate 50 / Pro series, which will be released on September 6, may provide emergency SMS services through satellite communications supported by the Beidou system.
