Abstract
A method and an apparatus for determining a security protection mode. In the method, a terminal device may determine a security protection mode of a second communications mode based on security protection information in a first communications mode. In this way, when switching from the first communications mode to the second communications mode, the terminal device may directly use the security protection mode corresponding to the second communications mode to protect transmitted data, so as to ensure data security of the terminal device after communications mode switching is performed.
