Abstract

Disclosed are a terminal control method and device, used for implementing control on a user equipment (UE) with a proximity perception capability when a D2D communication mechanism for mutual discovery even direct communication between mobile devices is introduced to a network. The method is: an MME receiving a D2D request message of a UE that is sent by a base station, determining requested D2D characteristics according to the D2D request message, determining an acceptable D2D characteristic in the requested D2D characteristics, and sending the accepted D2D characteristic to the base station; and after receiving the accepted D2D characteristic returned by the MME, the base station determining whether to accept the D2D request of the UE, and if yes, the base station performing resource configuration and instructing the UE to perform the accepted D2D characteristic; otherwise, the base station rejecting the D2D request of the UE. Also disclosed are another terminal control method and device, and further disclosed is a terminal control system.
