Abstract: A method for security handling in a mobility of a terminal device, where the method includes: a target access and mobility management function (AMF) entity receiving a first message for registering a terminal device; the target AMF entity sending a second message to a source AMF entity after receiving the first message; the source AMF entity deriving a first key based on a key between the source AMF entity and the terminal device; the source AMF entity sending the first key to the target AMF entity; the target AMF entity determining to use the first key based on security related information after receiving the first key; and the target AMF entity determining a communication key between the target AMF entity and the terminal device based on the first key after determining to use the first key.

Abstract: A method includes receiving, by a mobility management entity (MME), a redirection request message from an access and mobility management function (AMF) node, where the redirection request message includes key-related information. The method also includes generating, by the MME, an encryption key and an integrity protection key based on the key-related information. The redirection request message is used to request to hand over a voice service from a packet switched (PS) domain to a circuit switched (CS) domain.

Abstract: Embodiments of the present invention provide a communication method. The communication method includes: performing, by a terminal, a handover from a source base station to a target base station via an interface between the source base station and the target base station, obtaining, by the target base station, a first security capability, and sending, by the target base station, the first security capability to another base station, to establish dual connections. The source base station does not support the first security capability, and the target base station, the another base station, and a core-network network element support the first security capability. The target base station obtains the first security capability, so that the terminal can establish the dual connections to the target base station and the another base station.

Abstract: A communication method and a communications apparatus in which the method includes: a terminal device receiving a first authentication request from a security function network element, and obtaining authentication reference information based on the first authentication request, where the authentication reference information is a response value, a resynchronization token, or a cause indication value. The terminal device sends an authentication response message to the security function network element, where the authentication response message includes a first information element used to carry the response value, a second information element used to carry the resynchronization token, and a third information element used to carry the cause indication value, and the authentication reference information is carried in an information element corresponding to the authentication reference information.

Abstract: A service application programming interface (API) invoking method where a security method applied to an API exposing function entity is updated from an original security method to a new security method, and where the security method of the API exposing function entity is used for communication between the API exposing function entity and an invoker. The method includes: obtaining, by the invoker, a new security method of the API exposing function entity; and sending, by the invoker, a first invoking request to the API exposing function entity using the new security method, where the first invoking request includes a name of a service API, and where the first invoking request is used to invoke the service API.
