Abstract: A key generation method includes determining, by an access and mobility management function node, key-related information. The method also includes sending, by the access and mobility management function node, a redirection request message to a mobility management entity. The redirection request message includes the key-related information, and 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. The method further includes receiving, by the mobility management entity, the redirection request message. The method additionally includes generating, by the mobility management entity, an encryption key and an integrity protection key for the voice service based on the key-related information.

Abstract: This application provides a method for controlling a connection between a terminal and a network, and an apparatus. The method includes: receiving, by a terminal, a packet filter; and discarding, by the terminal, an uplink data packet matching the packet filter. Based on this solution, a connection can be blocked near a source (that is, the connection is blocked from the terminal), to reduce traffic exchanged between the terminal and a user plane network element. Compared with an existing technical solution, the terminal implements traffic control to reduce a quantity of uplink data packets sent to the user plane network element, thereby reducing load of the user plane network element.

Abstract: The present disclosure discloses a link re-establishment method, an apparatus, and a system. The method includes: obtaining, by user equipment UE, a MAC of the UE based on a NAS integrity key and a first MAC generation parameter, where the first MAC generation parameter includes an identifier of the UE; sending, by the UE, a re-establishment request message to a target RAN, where the re-establishment request message includes the MAC and the first MAC generation parameter; and receiving, by the UE, a re-establishment response message of the target RAN. The UE triggers, by sending the re-establishment request message, a CP functional entity to perform authentication on the UE. This resolves a prior-art problem that an excessively long time is consumed to re-establish a connection to a target RAN by using an RAU procedure, increases a speed of re-establishing a connection between UE and a network, and improves user experience.
