Method of device-to-device discovery and apparatus thereof
First Claim
1. A method of performing device-to-device (D2D) communication in a discovery terminal, the method comprising:
- receiving a discovery identifier of the discovery terminal from a D2D server;
performing an authentication procedure for restricted discovery of an application located in the discovery terminal with the D2D server, wherein the authentication procedure determines whether the application is authenticated for use of a feature of restricted discovery;
performing an authorization for a restricted discovery operation of the application located in the discovery terminal with the D2D server; and
obtaining terminal information of a discoverable terminal from the D2D server when the authorization is completed,wherein the discoverable terminal performs the restricted discovery operation with the discovery terminal,wherein the discovery identifier is mapped to a terminal identifier of the discovery terminal, andwherein the discovery identifier is used for identifying the discovery terminal in the D2D communication.

Abstract
Disclosed are a method of device-to-device discovery and an apparatus for the same. A method of device-to-device discovery performed in a discovery terminal may include receiving a discovery identifier of the discovery terminal from a device-to-device server; performing an authorization procedure on performing the restricted discovery of an application located in the discovery terminal with the device-to-device server; and obtaining terminal information of a discoverable terminal as a counterpart terminal with which performs the restricted discovery from the device-to-device server, when the authorization is completed. Thus, the device-to-device discovery may be performed efficiently.

10. A method of performing a device-to-device (D2D) communication in a discovery terminal, the method comprising:
-
transmitting a restricted discovery activation request message to request activation of a restricted discovery operation of a discoverable terminal to a D2D server; performing an authentication procedure for restricted discovery of an application located in the discovery terminal with the D2D server, wherein the authentication procedure determines whether the application is authenticated for use of a feature of restricted discovery; receiving radio resource information for the restricted discovery operation via a base station interworking with the D2D server, when the restricted discovery operation of the discoverable terminal is activated; receiving a restricted discovery activation response message in response to the restricted discovery activation request message from the D2D server; and performing the restricted discovery operation with the discoverable terminal using radio resources indicated by the radio resource information. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of performing a device-to-device (D2D) communication in a discovery terminal, the method comprising:
-
transmitting a restricted discovery deactivation request message to request deactivation of a restricted discovery operation of a discoverable terminal to a D2D server; receiving information on releasing radio resources allocated for the restricted discovery operation via a base station interworking with the D2D server, when the restricted discovery operation of the discoverable terminal is deactivated; receiving a restricted discovery deactivation response message in response to the restricted discovery deactivation request message from the D2D server; and transitioning to an idle state. - View Dependent Claims (18, 19, 20)
