摘要： A method, an apparatus, and a system for dual-connectivity communication, where the method may include: sending, by a master Node, a first message to a secondary Node, where the first message includes a user plane security policy, and the user plane security policy is used by the secondary Node to determine a user plane security protection method between the secondary Node and a user terminal; receiving, by the master Node, a second message from the secondary Node, where the second message includes user plane security enabling type indication information, and the user plane security enabling type indication information is used to indicate a user plane security protection method between the secondary Node and the user terminal; and sending, by the master Node, a third message to the user terminal, where the third message includes the user plane security enabling type indication information.

摘要： A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message. This application is applicable to a process of performing security protection on a NAS message.

摘要： This application discloses a method and an apparatus for obtaining an identifier of a terminal device. The method is performed by a gateway node and includes: receiving a first message sent by a terminal device, and sending a second message to a control plane node, where both the first message and the second message carry a temporary identifier of the terminal device; receiving a third message sent by the control plane node, where the third message is sent by the control plane node when the control plane node cannot obtain a permanent identifier of the terminal device; sending a fourth message to the terminal device based on the third message; receiving a fifth message sent by the terminal device, where the fifth message carries the permanent identifier of the terminal device; and sending the permanent identifier to the control plane node based on the fifth message.

摘要： A data transmission method includes calculating, by a user equipment (UE), a first message authentication code of first location privacy setting data, sending, by the UE, the first message authentication code and the first location privacy setting data to a data management network element, receiving, by the UE, a second message authentication code from the data management network element, calculating, by the UE, a third message authentication code of the first location privacy setting data, determining, by the UE, that the first location privacy setting data is not tampered with when the second message authentication code is the same as the third message authentication code.

摘要： A method, a related apparatus, and a system for recovering a called service of a terminal are provided. The method includes: when a called request of a user terminal is received, querying an initial proxy-call session control function (P-CSCF) entity with which the user terminal currently registers; if it is detected that the initial P-CSCF is faulty, selecting an available P-CSCF and sending, to the available P-CSCF, a notification message that carries a redundancy identifier, where the redundancy identifier is used to instruct the available P-CSCF to trigger the user terminal to re-register with the P-CSCF; and when a registration complete message sent by the P-CSCF with which the user terminal re-registers is received, delivering the called request to the re-registered P-CSCF to bear a called service of the user terminal.

摘要： A communication method and a related apparatus, where a base station obtains a security policy, where the security policy includes integrity protection indication information, and where the integrity protection indication information is used to instruct the base station whether to enable integrity protection for a terminal device. When the integrity protection indication information instructs the base station to enable integrity protection for the terminal device, the base station sends a target user plane integrity protection indication information to the terminal device.
