Abstract: A method for determining a user plane security algorithm, a system, and an apparatus. The method may include: a second device selects a non-null user plane confidentiality protection algorithm based on a security capability of a first device and a security capability of the second device in a case in which user plane confidentiality protection between the second device and the first device is enabled and control plane confidentiality protection between the second device and the first device is not enabled. The second device sends a first message to the first device. The first message includes first algorithm indication information indicating the user plane confidentiality protection algorithm. Therefore, the first device can obtain the non-null user plane confidentiality protection algorithm. Embodiments can be adopted to determine an effective user plane confidentiality protection algorithm, for confidentiality protecting user plane data.

Abstract: A method for obtaining an identifier of a terminal device includes a key management network element receiving, from a first terminal device, a first key request including a first identifier, where the first identifier is an anonymous identifier or a temporary identifier of a second terminal device. The key management network element sends, to a unified data management network element, a first request including the first identifier. The unified data management network element determines a SUPI of the second terminal device based on the first identifier, and sends, to the key management network element, a first response including the SUPI. In response to an authorization check performed on the second terminal device based on the SUPI succeeds, the key management network element sends a first key response to the first terminal device, where the first key response includes a secure communication parameter.

Abstract: This application provides a communication method, apparatus, and system. The method includes: After a second node sends first indication information to a first node by using a message that is not security protected, the first node may request an IAB donor node to verify whether the first indication information is trustworthy, so that the first node performs a subsequent operation based on a verification result of the IAB donor node. This can eliminate a security risk in a communication process, and help improve communication quality.

Abstract: 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.

Abstract: Embodiments of this application relate to a method and a device for protecting privacy. The method includes: sending, by a remote terminal, a first message to a mobility management entity by using a relay terminal, where the first message includes first identity information of the remote terminal, and the first message is used by the mobility management entity to obtain an international mobile subscriber identity IMSI of the remote terminal based on the first identity information of the remote terminal, where the first identity information is a proximity service relay user key identity PRUK ID. Because the first identity information is used to replace the IMSI, interception of the IMSI by the relay terminal is avoided, and user privacy is protected.

Abstract: 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.

Abstract: This application provides security activation methods and communication apparatuses. In an example method, a first access network device in a first communication standard requests a second access network device in a second communication standard to allocate a resource for dual connectivity of a terminal device, and sends, to the second access network device, a user plane security policy. The first access network device further receives identification information of a bearer and a security activation status from the second access network device and sends the identification information of the bearer and the security activation status to the terminal device.

Abstract: Embodiments of this application provide a communication method and an apparatus to resolve a PC5 unicast establishment failure due to inconsistency between security parameters of terminal devices in a V2X scenario with security negotiation introduced into a PC5 unicast establishment procedure. The communication method includes: A first direct communication discovery name management function network element obtains a security parameter of a first terminal device. A security parameter is required for establishing a PC5 connection between the first terminal device and a second terminal device. The first direct communication discovery name management function network element receives a security parameter of the second terminal device from a second direct communication discovery name management function network element and determines, based on whether the security parameter of the first terminal device matches the security parameter of the second terminal device, whether the first terminal device and the second terminal device support mutual communication.
