Abstract: This application discloses a key obtaining method and a communication apparatus. A remote terminal device sends a first identifier and a relay service code to a relay terminal device. The first identifier is an identifier that is of the remote terminal device and that is corresponding to the relay service code, or the first identifier is an anonymous identifier of the remote terminal device. The remote terminal device generates, based on a first shared key, the relay service code, and at least one first freshness parameter, a root key for communication between the remote terminal device and the relay terminal device. A remote authentication service function network element is an authentication service function network element that serves the remote terminal device, and the first shared key is a key shared between the remote terminal device and the remote authentication service function network element.

Abstract: A user plane security enforcement information determining method and an apparatus are provided, to ensure a security requirement of transmitted data of a remote device. In this application, a session management network element may receive a first request for creating a relay-type session of a first terminal device. Then, the session management network element determines first user plane security enforcement information of the session based on first information, and sends the first user plane security enforcement information of the session to an access network device, where the first user plane security enforcement information of the session is for determining a first user plane security activation status of the session between the first terminal device and the access network device.

Abstract: This application provides a key management method, a device, and a system. The method includes: A terminal device sends a first application session establishment request message to a first application function network element, where the establishment request message carries identification information of a first key, and the first key is an authentication and key management for applications AKMA key. The terminal device receives a first authentication request message in a procedure of the re-authentication. The terminal device sends a response message for the first authentication request message in the procedure of the re-authentication. The terminal device receives a response message for the establishment request message. The terminal device derives a communication key between the terminal device and the first application function network element by using the first key.

Abstract: This application provides a QoS flow control method and an apparatus. An SMF network element receives first indication information sent by an access network apparatus, where the first indication information is used to indicate that a first QoS target of a QoS flow cannot be met; and the SMF network element does not process the QoS flow if the SMF network element receives second indication information in a first preset time; or the SMF network element deletes or modifies the QoS flow if the SMF network element does not receive second indication information in a first preset time, where the second indication information is used to indicate that the first QoS target can be met.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving first indication information by a first network element from a second network element, where the first indication information is used to indicate that a current condition supports establishment of a session of a first network for a terminal apparatus. The first network element obtains first quality of service (QoS) control information of a first session of the terminal apparatus after receiving the first indication information, where the first session is a session established by the terminal apparatus by using a second network. The first network element sends the first QoS control information to the second network element.

Abstract: The present disclosure relates to communication methods and apparatus. One example method includes receiving, by a target service entity, a first request message from a first participating service entity, and sending, by the target service entity, a first response message to the first participating service entity. The first request message comprises an identity of a target multicast bearer and a group identity of a terminal group. The first response message is used to instruct the first participating service entity to use the target multicast bearer to send service data of the terminal group.
