Abstract

This application discloses a method and related device for configuring an EPS NAS security algorithm in the field of communication technology. In the technical solution provided in this application, the access and mobility management functional entity needs to determine whether the selected EPS NAS security algorithm has been successfully provided to the 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 functional 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 functional entity can successfully configure the EPS NAS security algorithm for the terminal device.
