Abstract: Solution for security negotiation during handover of a user equipment (UE) between different radio access technologies are provided. In the solution, the UE receives NAS security information and AS security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a LTE system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a UTRAN, to the LTE system.

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.
