A communication method and a communications apparatus are provided. The method includes: when receiving a first PDU session establishment request sent by a UE, encrypting, by an access and management network element (AMF), user information in the request, to obtain encrypted user information; and sending, by the AMF, a second PDU session establishment request to an SMF in response to the first PDU session establishment request, where the second PDU session establishment request carries the encrypted user information. In this manner, after the UE accesses a core network, an AMF entity may encrypt user information of the UE. The interaction information between NF entities, for example, the AMF entity and an SMF entity, carries the encrypted user information, which helps prevent user privacy leakage.
