System and method for device to device (D2D) communication
First Claim
1. A method for controlling a User Equipment (UE), the method comprising:
- receiving, by a Mobility Management Entity (MME), a Device to Device (D2D) request message of a UE transmitted by an evolved Node B (eNB), determining, according to the D2D request message, requested D2D features, determining acceptable one of the requested D2D features and transmitting an accepted D2D feature to the eNB; and
upon reception of the accepted D2D feature transmitted by the MME, judging, by the eNB, whether to accept the D2D request of the UE, and if the eNB determines to accept the D2D request, then configuring by the eNB, resource and instructing the UE to perform configuration of the accepted D2D feature;
if the eNB determines not to accept the D2D request, rejecting, by the eNB, the D2D request of the UE.

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.

9. A network-side device, comprising:
-
a receiver configured to receive a Device to Device (D2D) request message of a User Equipment (UE) transmitted by an evolved Node B (eNB); a processor configured to determine, according to the D2D request message, requested D2D features and to determine acceptable one of the requested D2D features; and a transmitter configured to transmit an accepted D2D feature to the eNB; wherein the processor is configured to determine, according to subscription data of the UE and a network policy, a set of D2D features capable of serving the UE; and
to determine one of the D2D features requested by the UE, which belongs to the set is the acceptable one of the requested D2D features. - View Dependent Claims (10)

11. A network-side device, comprising:
-
a transceiver configured to receive a Device to Device (D2D) request message of a User Equipment (UE), to transmit the D2D request message to a Mobility Management Entity (MME) and to receive an accepted D2D feature returned by the MME, wherein the MME determines, according to subscription data of the UE and a network policy, a set of D2D features capable of serving the UE, and determines one of D2D features requested by the UE, which belongs to the set is the accepted D2D feature; and a processor configured to judge, after the communicating component receives the accepted D2D feature, whether to accept the D2D request of the UE, and if the processor determines to accept the D2D request of the UE, to configure resource and instruct the UE to perform configuration of the accepted D2D feature;
if the processor determines not to accept the D2D request of the UE, to reject the D2D request of the UE. - View Dependent Claims (12, 13)
