Abstract

Provided are a method and user equipment for performing device-to-device communication by a user equipment in a wireless communication system, the method, performed by a user equipment, of performing device-to-device communication in a wireless communication system may include: receiving information about a data path, from a network entity; determining, based on the information about the data path, a data path for the device-to-device communication as a path through a Uu interface or a path through a PC5 interface; and performing the device-to-device communication via the determined data path.

Claims (18)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

receiving information about a communication path from a network entity, wherein the information about the communication path indicates a path through a Uu interface or a path through a PC5 interface;

selecting, based on the information about the communication path, a communication path for a proximity-based service (ProSe) service as the path through the Uu interface or the path through the PC5 interface; and

performing a communication with another UE via the selected communication path,

wherein in case that the information about the communication path indicates the path through the PC5 interface and the UE and the another UE are not close to each other, the communication path for the ProSe service is selected as the path through the Uu interface.

2. The method of claim 1 , wherein the information about the communication path is determined by the network entity based on service information provided by a ProSe application server, the service information including information about a path selected by the ProSe application server.

3. The method of claim 1 , wherein the network entity is a policy control function (PCF).

4. The method of claim 1 , further comprising performing a registration procedure with a network.

5. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

a processor coupled with the transceiver and configured to:

receive information about a communication path from a network entity, wherein the information about the communication path indicates a path through a Uu interface or a path through a PC5 interface;

select, based on the information about the communication path, a communication path for a proximity-based service (ProSe) service as the path through the Uu interface or the path through the PC5 interface; and

perform a communication with another UE via the selected communication path,

wherein in case that the information about the communication path indicates the path through the PC5 interface and the UE and the another UE are not close to each other, the communication path for the ProSe service is selected as the path through the Uu interface.

6. The UE of claim 5 , wherein the information about the communication path is determined by the network entity based on service information provided by a ProSe application server, the service information including information about a path selected by the ProSe application server.

7. The UE of claim 5 , wherein the network entity is a policy control function (PCF).

8. The UE of claim 5 , wherein the processor is further configured to perform a registration procedure with a network.
