Abstract

A mobile communication system, which supports D2D communication that is direct device-to-device communication that is performed by using a radio resource assigned from a network, comprises: a user terminal that transmits a D2D start request for starting the D2D communication to the network, wherein the D2D start request includes an application identifier indicating an application used by the user terminal in the D2D communication, and a terminal identifier indicating another user terminal that is a communication partner of the user terminal in the D2D communication.

Claims

1. A mobile communication system, which supports D2D communication that is direct device-to-device communication that is performed by using a radio resource assigned from a network, comprising:

a user terminal that transmits a D2D start request for starting the D2D communication to the network, wherein

the D2D start request includes an application identifier indicating an application used by the user terminal in the D2D communication, and a terminal identifier indicating another user terminal that is a communication partner of the user terminal in the D2D communication.

2. The mobile communication system according to claim 1, wherein, after the D2D start request is received, on the basis of the application identifier and the terminal identifier, the network determines whether data, which is transmitted and received to and from the user terminal, is data of the D2D communication.

3. A user terminal in a mobile communication system, which supports D2D communication that is direct device-to-device communication that is performed by using a radio resource assigned from a network, comprising:

a transmission unit that transmits a D2D start request for starting the D2D communication to the network, wherein

the D2D start request includes an application identifier indicating an application used by the user terminal in the D2D communication, and a terminal identifier indicating another user terminal that is a communication partner of the user terminal in the D2D communication.

4. A processor provided in a user terminal in a mobile communication system that supports D2D communication that is direct device-to-device communication that is performed by using a radio resource assigned from a network, wherein

the processor executes a process of transmitting a D2D start request for starting the D2D communication to the network, and

the D2D start request includes an application identifier indicating an application used by the user terminal in the D2D communication, and a terminal identifier indicating another user terminal that is a communication partner of the user terminal in the D2D communication.

5. A storage medium provided in a user terminal in a mobile communication system that supports D2D communication that is direct device-to-device communication that is performed by using a radio resource assigned from a network, wherein

the storage medium stores a program for performing a process of transmitting a D2D start request for starting the D2D communication to the network, and

the D2D start request includes an application identifier indicating an application used by the user terminal in the D2D communication, and a terminal identifier indicating another user terminal that is a communication partner of the user terminal in the D2D communication.
