Abstract: This application discloses a security parameter obtaining method, an apparatus, and a system, to ensure security of a private network service. In this application, security parameters used to derive an air interface control plane key and an air interface user plane key are separately generated, the security parameter used to derive the air interface user plane key is derived by using a root key of a private network, and derivation is completed in the private network, to prevent the root key of the private network and a process of deriving the security parameter from being exposed in a public network. In this way, when the air interface user plane key is used to securely transmit service data, security of service data transmission over an air interface can be improved.

Abstract: A communication method includes receiving, by an access network (AN) node, indication information from a mobility management device. The indication information is indicative of a security policy of a quality of service (QoS) flow. The method also includes obtaining, by the access network node based on the indication information, security information of a radio bearer corresponding to the QoS flow. The security information is indicative of a security policy of the radio bearer. The method further includes sending, by the access network node, an identifier of the radio bearer and the security information of the radio bearer to a terminal.

Abstract: Embodiments of this application provide a data transmission method, including: receiving, by user equipment, a first message, where the first message is used to instruct the user equipment to activate a reflective quality of service RQ mechanism; generating, by the user equipment, an implicit quality of service implicit QoS rule according to the RQ mechanism; receiving, by the user equipment, a second message, where the second message is used to instruct the user equipment to stop using the RQ mechanism; and stopping, by the user equipment, using the RQ mechanism, and deleting the implicit QoS rule. The user equipment receives the second message indicating that using of the RQ mechanism needs to be stopped, and deletes the implicit QoS rule, so as to implement switching between an explicit QoS rule and the implicit QoS rule, and flexibly configure a QoS rule for uplink data according to a policy of an operator.
