METHOD OF DEVICE-TO-DEVICE DISCOVERY AND APPARATUS THEREOF
First Claim
1. A method of restricted discovery performed in a discovery terminal, the method comprising:
- 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.

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 activating a restricted discovery performed in a discovery terminal, the method comprising:
-
transmitting a restricted discovery activation request message to a device-to-device server to activate the restricted discovery of the discoverable terminal; receiving information on radio resources used for the restricted discovery through a base station interworking with the device-to-device server, when the restricted discovery of the discoverable terminal is activated; receiving a restricted discovery activation response message in response to the restricted discovery activation request message from the device-to-device server; and performing the restricted discovery with the discoverable terminal through radio resources indicated by the information on radio resources. - View Dependent Claims (11, 12, 13, 14, 15, 16)

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