Abstract
A method for protecting a truncated parameter includes that a mobility management network element determines whether a terminal that accesses a network meets a preset condition, where the preset condition includes that the terminal uses a control plane cellular Internet of things (CIoT) 5th generation system (5GS) optimization function. The mobility management network element sends, to the terminal when the terminal meets the preset condition, a downlink non-access stratum (NAS) message on which NAS security protection is performed using a NAS security context, where the downlink NAS message includes a truncated parameter.
