METHOD, CONTROL NETWORK ELEMENT, AND SYSTEM FOR SECURITY ALGORITHM NEGOTIATION AND PROCESSING

摘要

Embodiments of the present invention provide a negotiation processing method for a security algorithm, a control network element, and a control system. The negotiation processing method for a security algorithm includes: selecting, by a control network element according to a security capability of first UE and a security capability of second UE, a security algorithm supported by both the first UE and the second UE; and notifying, by the control network element, the selected security algorithm to the first UE and the second UE. By means of the embodiments of the present invention, negotiation of a security algorithm between two UEs in proximity communication can be implemented under the control of a control network element.
