Abstract

There are provided a method of a device-to-device (D2D) discovery and an apparatus thereof. The method of the device-to-device discovery performed in a terminal may includes registering a discovery service of the terminal using service information on a service provided from an user; transmitting a discovery transmission activation request to a network in which the terminal is located; receiving a response in response to the discovery transmission activation request from the network; and transmitting a discovery message when the response is an approval message.

Claims

1. A method of device-to-device discovery performed in a terminal, comprising:

registering a discovery service of the terminal using service information on a service provided by an user;

transmitting a discovery transmission activation request to a network in which the terminal is located;

receiving a response in response to the discovery transmission activation request from the network; and

transmitting a discovery message when the response is an approval message.

2. The method of claim 1, wherein the service information includes information on an URL of a server which provides information on service category and detail information on the service provided.

3. The method of claim 2, wherein the information on a service category is registered using a service code which corresponds to the service category based on a predetermined code mapping scheme.

4. The method of claim 1, wherein the discovery transmission activation request includes a discovery type, a discovery state, and a discovery range class.

5. The method of claim 1, wherein the response includes information on radio resources allocated for transmission of the discovery message.

6. The method of claim 5, wherein the discovery message is transmitted using the radio resources indicated by the response.

7. The method of claim 1, wherein the discovery message includes the service code corresponding to the service category, a discovery identifier corresponding to the terminal.

8. A method of device-to-device discovery performed in a terminal, comprising:

being inputted service information on a service desired to be provided through the terminal;

transmitting a discovery reception activation request to a network in which the terminal is located;

receiving a response in response to the discovery reception activation request from the network; and

searching a discovery message from a counterpart terminal when the response is an approval message.

9. The method of claim 8, wherein the service information includes information on a service category of the service and information on keywords of the service.

10. The method of claim 9, wherein the information on a service category is registered using a service code which corresponds to the service category based on a predetermined code mapping scheme.

11. The method of claim 8, wherein the discovery reception activation request includes a discovery type and a discovery state.

12. The method of claim 8, wherein the response includes information on radio resources allocated for reception of the discovery message.

13. The method of claim 12, wherein the discovery message is searched and received on the radio resources indicated by the response.

14. The method of claim 8, wherein the discovery message includes a service code of a service provided by the counterpart terminal and a discovery identifier corresponding to the terminal which transmitted the discovery message.

15. The method of claim 14, further includes

determining whether the service code included in the discovery message is the same with the service code indicated by the service information or not;

and

requesting additional information related to the service provided by the counterpart terminal when the service code included in the discovery message is the same with the service code indicated by the information on a service.

16. The method of claim 15, wherein the additional information includes an identifier of the counterpart terminal transmitting the discovery message and an address of a server providing detail information related to the service provided by the counterpart terminal.
