Abstract: Embodiments of the present application provide a communication method and apparatus. The method comprises: a terminal device in a registered state determines whether a temporary identity assigned by a network side to the terminal device has expired; when determining that the temporary identity has expired, the terminal device sends a first message to a mobility management network element by means of an access device, the first message comprising a routing identifier and an encrypted identity, wherein the routing identifier is used for determining, by the access terminal, a mobility management network element serving the terminal device. On this basis, in order to prevent being tracked, the terminal device uses an encrypted permanent identity instead of the original 5G-TMSI, so that the terminal device can be prevented from being tracked. Compared with the prior art, in this solution, the 5G-TMSI used by the terminal device remains unchanged, but the 5G-TMSI is not used directly, instead, the encrypted permanent identity is used, so that an attacker cannot obtain identity information of the terminal device, and accordingly cannot track the location of the terminal device.
