This application discloses methods and related apparatuses for configuring an EPS NAS security algorithm in the field of communication technologies. In an example technical solution provided in this application, an access and mobility management function entity determines 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.

Method for configuring evolved packet system non-access stratum security algorithm and related apparatus

A handover handling method and apparatus applied to a scenario in which user equipment (UE) is handed over from a first access and management function (AMF) to a second AMF, and where the method includes receiving, by the UE, a handover command message from a first access network device, wherein the handover command message carries a Non-Access Stratum container (NASC), performing, by the UE, integrity verification on the NASC, and continuing, by the UE, to use a first NAS security context when the integrity verification performed on the NASC fails, wherein the first NAS security context is a security context used between the UE and the first AMF.

Handover handling method and apparatus

A session processing method in wireless communications and a terminal device include sending, by the terminal device, a session establishment request to a core network device, where the session establishment request requests to establish a session, and the session is supported by a network slice corresponding to the session, determining, by the terminal device, that establishment of the session fails, determining, by the terminal device, a forbidden time period corresponding to the session, and forbidding, by the terminal device, the terminal device from sending the session establishment request within the forbidden time period.
