Abstract
If a master device in device-to-device direct communication designates an object type of a target to be communicated with, transmits a target discovery request message including the object type of the target to be communicated with to a plurality of neighboring target devices, and receives a target discovery response message from one or more target devices corresponding to the object type of the target to be communicated with among the plurality of target devices, the master device determines one target device among one or more target devices as the target to be communicated with.
Claims14
A method for discovering a target to communicate with a master device in device-to-device direct communication, the method comprising:
- designating an object type of the target to be communicated with;
- transmitting a target discovery request message including the object type of the target to be communicated with to a plurality of neighboring target devices;
- receiving target discovery response messages from one or more target devices corresponding to the object type of the target to be communicated with among the plurality of target devices;
- and
- determining one target device among one or more target devices as the target to be communicated with.
A method for responding to a master device discovering a target to be communicated with from one or more target devices in device-to-device direct communication, the method comprising:
- receiving a target discovery request message including an object type of the target to be communicated with from the master device;
- determining whether or not an object type of the target device corresponds to an object type of the target to be communicated with;
- and
- if the object type of the target device corresponds to the object type of the target to be communicated with, transmitting a target discovery response message to the master device.
An apparatus for discovering a target to be communicated with in device-to-device direct communication, the apparatus comprising:
- an object filtering unit determining an object type of the target to be communicated with;
- transmitting and receiving unit transmitting a target discovery request message including the object type of the target to be communicated with and receiving a target discovery response message from one or more target devices corresponding to the object type of the target to be communicated with among a plurality of target devices;
- and
- a controlling unit determining a target to be communicated with among one or more target devices.
