Abstract
A communication control method according to a present embodiment comprises: a step of transmitting, by a first base station, to a third base station that is a neighboring base station of the first base station, a first resource message relating to a first D2D resource used for the D2D proximity service in the first base station. The first resource message includes information on the first D2D resource and a second D2D resource used for the D2D proximity service in a second base station that is a neighboring base station of the first base station.
Claims12
A communication control method used in a mobile communication system that supports a D2D proximity service including D2D communication that is direct device-to-device communication, comprising:
- a step of receiving, by a first base station, a second resource message from a third base station that is a neighboring base station of the first base station;
- and
- a step of transmitting, by the first base station, to a second base station that is a neighboring base station of the first base station and different from the third base station, a first resource message, wherein
- the second resource message includes information indicating a second D2D transmission resource available for transmission of a D2D radio signal in the third base station and information indicating a fourth D2D transmission resource available for transmission of a D2D radio signal in a fourth base station that is not a neighboring base station of the first base station but is a neighboring base station of a third base station,
- the first resource message includes information indicating a first D2D transmission resource available for transmission of a D2D radio signal in the first base station, information indicating the second D2D transmission resource and information indicating the fourth D2D transmission resource.
A communication control method used in a mobile communication system that supports a D2D proximity service including D2D communication that is direct device-to-device communication, comprising:
- a step of receiving, by a first base station, a second resource message from a third base station that is a neighboring base station of the first base station;
- and
- a step of transmitting, by the first base station, to a second base station that is a neighboring base station of the first base station and different from the third base station, a first resource message, wherein
- the second resource message includes information indicating a second D2D transmission resource available for transmission of a D2D radio signal in the third base station and information indicating a fifth D2D transmission resource available for transmission of a D2D radio signal in a fifth base station that is not a neighboring base station of the first base station,
- the first resource message includes information indicating a first D2D transmission resource available for transmission of a D2D radio signal in the first base station, information indicating the second D2D transmission resource and information indicating the fifth D2D transmission resource, and
- the communication control method further comprises:
- a step of setting, by the second base station, a new third D2D reception resource by adding a radio resource corresponding to the fifth D2D transmission resource to a third D2D reception resource available for the reception of a D2D radio signal in the second base station, only when a hop count of information indicating the fifth D2D transmission resource is equal to or below an upper-limit value.
A first base station used in a mobile communication system that supports a D2D proximity service including D2D communication that is direct device-to-device communication, comprising:
- a receiver configured to receive a second resource message from a third base station that is a neighboring base station of the first base station;
- a transmitter configured to transmit, to a second base station that is a neighboring base station of the first base station and different from the third base station, a first resource message, wherein
- the second resource message includes information indicating a second D2D transmission resource available for transmission of a D2D radio signal in the third base station and information indicating a fourth D2D transmission resource available for transmission of a D2D radio signal in a fourth base station that is not a neighboring base station of the first base station but is a neighboring base station of a third base station,
- the first resource message includes information indicating a first D2D transmission resource available for transmission of a D2D radio signal in the first base station, information indicating the second D2D transmission resource and information indicating the fourth D2D transmission resource.
