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.

determining, by the MME, one of the D2D features requested by the UE, which belongs to the set is the acceptable D2D feature.

8. The method according to claim 7, wherein transmitting, by the MME, the accepted D2D feature to the eNB comprises:

transmitting, by the MME, the accepted D2D feature to the eNB by carrying it in an Initial Context Create message;

or

transmitting, by the MME, the accepted D2D feature to the eNB by carrying it in an S1 interface application protocol layer (S1-AP) message.

9. The method according to claim 1, wherein judging, by the eNB, whether to accept the D2D request of the UE comprises:

judging, by the eNB, according to a current use condition of radio resources and interference strength whether to accept the D2D request of the UE.

10. The method according to claim 9, wherein configuring, by the eNB, the resource comprises:

allocating, by the eNB, resource to be occupied for performing the D2D feature accepted by the MME or releasing resource occupied by the D2D feature accepted by the MME.

12. A method for controlling a User Equipment (UE), the method comprising:

receiving, by an evolved Node B (eNB), a Device to Device (D2D) request from a UE; and

judging, by the eNB whether to accept the D2D request of the UE, and if so, then transmitting the D2D request message to a Mobility Management Entity (MME), and configuring resource and instructing the UE to perform configuration of an accepted D2D feature returned by the MME upon reception of the accepted D2D feature;

otherwise, rejecting the D2D request of the UE,

wherein the accepted D2D feature returned by the MME is acceptable one of the D2D features requested by the D2D request message, which is determined by the MME according to the D2D request message.

13. The method according to claim 12, wherein judging, by the eNB, whether to accept the D2D request of the UE comprises:

judging, by the eNB according to a current use of radio resources and interference strength whether to accept the D2D request of the UE.
