Abstract
A communication method in a wireless communication system supporting device-to-device (D2D) communication is provided. The communication method includes transmitting a first message including information for identifying a relay to discover a relay user equipment (UE) that performs a relay function in the D2D communication, and receiving a second message including information about the relay UE that performs the relay function, from the relay UE that has received the first message, the second message being transmitted in response to the first message.
Claims24
A communication method in a wireless communication system supporting device-to-device (D2D) communication, the communication method comprising:
- transmitting, by a remote user equipment (UE), a discovery message including information about the remote UE that transmits the discovery message and information for identifying a relay service to discover a relay UE that supports a relay function in the D2D communication, the information for identifying the relay service including a service code configured in the remote UE for indicating the relay service for public safety in the D2D communication;
- in response to the discovery message, receiving, by the remote UE, a discovery response message generated by a prose manager included in the relay UE thereby completing a direct discovery process;
- and
- establishing, by the remote UE, a connection with the relay UE receiving the discovery message based on information obtained during the direct discovery process.
A user equipment (UE) in a wireless communication system supporting device-to-device (D2D) communication, the UE comprising:
- a transceiver configured to transmit and receive data using the D2D communication;
- and
- a controller configured to:
- transmit a discovery message including information about the UE that transmits the discovery message and information for identifying a relay service to discover a relay UE that supports a relay function in the D2D communication, the information for identifying the relay service including a service code configured in the UE for indicating the relay service for public safety in the D2D communication,
- in response to the discovery message, receive a discovery response message generated by a prose manager included in the relay UE thereby completing a direct discovery process, and
- establish a connection with the relay UE receiving the discovery message based on information obtained during the direct discovery process.
A communication method in a wireless communication system supporting device-to-device (D2D) communication, the communication method comprising:
- receiving, by a relay user equipment (UE), a discovery message including information about a remote UE that transmits the discovery message and information for identifying a relay service, the discovery message for discovering the relay UE that supports a relay function in the D2D communication, the information for identifying the relay service including a service code configured in the remote UE for indicating the relay service for public safety in the D2D communication;
- in response to receiving the discovery message generated by a prose manager included in the relay UE, transmitting, by the relay UE, a discovery response message to the remote UE thereby completing a direct discovery process;
- and
- establishing, by the relay UE, a connection with the remote UE transmitting the discovery message based on information obtained during the direct discovery process.
A user equipment (UE) in a wireless communication system supporting device-to-device (D2D) communication, the UE comprising:
- a transceiver configured to transmit and receive data using the D2D communication;
- and
- a controller configured to:
- receive a discovery message including information about a remote UE that transmits the discovery message and information for identifying a relay service, the discovery message for discovering the UE as a relay UE that supports a relay function in the D2D communication, the information for identifying the relay service including a service code configured in the remote UE for indicating the relay service for public safety in the D2D communication,
- in response to receiving the discovery message generated by a prose manager included in the UE, transmit a discovery response message to the remote UE thereby completing a direct discovery process, and
- establish a connection with a remote UE transmitting the discovery message based on information obtained during the direct discovery process.
