Abstract: This application discloses an indoor-outdoor determining-based uplink transmission method and apparatus. A terminal device or a positioning device determines whether the terminal device is located indoors or outdoors. The terminal device or the positioning device sends a first message to an access network device, where the first message includes a first information element, and the first information element indicates whether the terminal device is located indoors or outdoors. The access network device determines an access parameter of the terminal device based on the first information element, where the access parameter includes an access frequency. According to the method disclosed in embodiments of this application, uplink transmission of the terminal device in a proper frequency band is implemented, and communication interference is reduced.
