Abstract
Methods for device-to-device communication based on wireless local area network are disclosed. A method for device-to-device communications performed in a first terminal may comprise configuring a default bearer by interworking with a core network supporting cellular communication, configuring a session by interworking with the core network, discovering a counterpart terminal performing device-to-device communications with the first terminal based on a request of configuring a dedicated bearer, and configuring a communication path according to a communication mode determined based on a result of the discovering. Therefore, according to the present invention, D2D communications using a Wi-Fi P2P may be supported efficiently.

A method for device-to-device communications performed in a first terminal, the method comprising:
- configuring a default bearer by interworking with a core network supporting a cellular communication;
- configuring a session by interworking with the core network;
- discovering a counterpart terminal performing device-to-device communications with the first terminal based on a request of configuring a dedicated bearer;
- and
- configuring a communication path according to a communication mode determined based on a result of the discovering.
A method for device-to-device communication performed in a first terminal, the method comprising:
- configuring a default bearer by interworking with a core network supporting cellular communication;
- configuring a session and a dedicated bearer by interworking with the core network;
- discovering a counterpart terminal performing device-to-device communications with the first terminal based on a request of discovery;
- and
- configuring a link for wireless local area network peer-to-peer communications with the counterpart terminal when a communication mode determined according to a result of the discovering is a wireless local area network peer-to-peer communication mode.
A method for device-to-device communication performed in a first terminal, the method comprising:
- configuring a default bearer by interworking with a core network supporting cellular communication;

- configuring a second session by interworking with the core network;
- discovering a counterpart terminal performing device-to-device communications with the first terminal based on a request of configuring a second dedicated bearer;
- and
- configuring a communication path according to a communication mode determined based on a result of the discovering.
A method for device-to-device communication performed in a first terminal, the method comprising:
- configuring a default bearer by interworking with a core network supporting cellular communication;
- configuring a session and a dedicated bearer by interworking with the core network;
- discovering a counterpart terminal performing device-to-device communications with the first terminal when a traffic load of the cellular communication is equal to or above a predetermined threshold;
- and
- configuring a link for wireless local area network peer-to-peer communications with the counterpart terminal when a communication mode determined according to a result of the discovering is a wireless local area network peer-to-peer communication mode.
