Abstract
Embodiments of this application relate to the field of communication technologies, and provide a data transmission method and an apparatus, to ensure security of radio capability information of a terminal in a transmission process. The method includes: A terminal performs NAS security protection on radio capability information based on a NAS security context before establishing an AS security context; then the terminal sends the NAS-security-protected radio capability information to a mobility management network element; and after receiving the NAS-security-protected radio capability information, the mobility management network element performs security deprotection on the NAS-security-protected radio capability information, to obtain and store the radio capability information of the terminal. In this way, in a scenario in which an access network device requires the radio capability information of the terminal, the mobility management network element may send the radio capability information to the access network device.
