Abstract: A security context update method and a communication apparatus are provided. The method is performed by a terminal, and includes: storing a security context of first access and a security context of second access when the first access of the terminal and the second access of the terminal enter a deregistered state. The first access is one of 3GPP access and non-3GPP access, the second access is the other of the 3GPP access and the non-3GPP access, and the first access and the second access are different. According to the method, when the terminal supports multiple records for multiple registration, storage occasions of NAS security contexts corresponding to the 3GPP access and the non-3GPP access are provided.

Abstract: Embodiments of the present invention provide a mode switching method and apparatus, which relate to the communications field and are used to improve user experience. The method includes: when a user equipment UE is in a state of accessing a first network in a first network mode of a first communications mode, determining, by the UE, whether the first network supports a first subsystem; enabling, by the UE, if the UE determines that the first network does not support the first subsystem and when the UE does not access a second network in the first communications mode, a second communications mode and accessing the second network in the second communications mode; and sending, by the UE, a first registration request message to the second network. The embodiments of the present invention are applicable to a service transmission scenario.

Abstract: This application discloses a method for configuring an EPS NAS security algorithm, and a related apparatus in the field of communication technologies. In the technical solution provided in this application, an access and mobility management function entity needs to determine whether a selected EPS NAS security algorithm has been successfully provided to a terminal device, and after determining that the selected EPS NAS security algorithm has not been successfully provided to the terminal device, the access and mobility management function entity provides the selected EPS NAS security algorithm to the terminal device again. According to the technical solution provided in this application, it is ensured that the access and mobility management function entity can successfully configure the EPS NAS security algorithm for the terminal device.
