Abstract
A method for performing discovery at a terminal in a communication system is provided. The method includes generating a discovery request message including discovery target information, transmitting the discovery request message to a Proximity Service (ProSe) server that is located in a core network of the communication system and that manages communication of the terminal, and receiving a result of a discovery operation from another entity that performs the discovery operation of the terminal using discovery identification information about the terminal. The other entity is selected based on the discovery target information by the ProSe server.
Claims29
A method for extending proximity service at a terminal in a communication system, the method comprising:
- generating a discovery request message including discovery target information;
- transmitting the discovery request message to a server that supports a proximity service for the terminal and another terminal;
- and
- receiving information obtained by a discovery operation from an agent entity that performs the discovery operation with the other terminal on behalf of the terminal using identification information of the terminal,
- wherein the agent entity is determined to be in proximity of the other terminal based on the discovery target information.
A method for extending proximity service of a terminal at a server supporting the proximity service for the terminal and another terminal in a communication system, the method comprising:
- receiving a discovery request message including discovery target information from the terminal;
- determining an agent entity for performing a discovery operation with the other terminal on behalf of the terminal using identification information of the terminal;
- and
- transmitting, to the determined agent entity, a discovery indication message to request performing the discovery operation of the terminal,
- wherein the agent entity is determined to be in proximity of the other terminal based on the discovery target information.
A method for extending proximity service of a terminal at an agent entity in a communication system, the method comprising:
- receiving a discovery indication message requesting a discovery operation from a server that supports a proximity service for a terminal and another terminal;
- transmitting a first discovery signal to the other terminal on behalf of the terminal using identification information of the terminal included in the discovery indication message;
- receiving a second discovery signal from the other terminal on behalf of the terminal;
- and
- transmitting, to the terminal, information obtained from the second discovery signal,
- wherein the agent entity is determined by the server to be in proximity of the other terminal based on discovery target information generated by the terminal.
A terminal for extending proximity service in a communication system, the terminal comprising:
- a controller configured to:
- generate a discovery request message including discovery target information,
- control transmission of the discovery request message to a server that supports a proximity service for the terminal and another terminal, and
- control reception of information obtained by a discovery operation from an agent entity that performs the discovery operation with the other terminal on behalf of the terminal using identification information of the terminal;
- and
- a transceiver configured to transmit and receive wireless signals under control of the controller,
- wherein the agent entity is determined to be in proximity of the terminal based on the discovery target information.
A server for extending proximity service of a terminal, the server supporting the proximity service for the terminal and another terminal in a communication system, the server comprising:
- a controller configured to:
- control reception of a discovery request message including discovery target information from the terminal,
- determine an agent entity for performing a discovery operation with the other terminal on behalf of the terminal using identification information of the terminal, and
- control transmission to the determined agent entity of a discovery indication message to request performing the discovery operation of the terminal;
- and
- a transceiver configured to transmit and receive wireless signals under control of the controller,
- wherein the agent entity is determined to be in proximity of the other terminal based on the discovery target information.
An agent entity for extending proximity service of a terminal in a communication system, the agent entity comprising:
- a controller configured to:
- control reception of a discovery indication message requesting a discovery operation from a server that supports a proximity service for a terminal and another terminal,
- control transmission of a first discovery signal to the other terminal on behalf of the terminal using identification information of the terminal included in the discovery indication message,
- control reception of a second discovery signal from the other terminal on behalf of the terminal, and
- control transmission of information obtained from the second discovery signal to the terminal;
- and
- a transceiver for transmitting and receiving wireless signals under control of the controller,
- wherein the agent entity is determined by the server to be in proximity of the other terminal based on discovery target information generated by the terminal.
