Benefits of technology

The present invention provides a way to control communication between two devices in a way that is efficient and effective. This is useful for situations where devices need to communicate with each other without going through a central system.

Problems solved by technology

However, the current 3GPP standards do not define specifications for appropriately controlling the D2D communication.
Thus, there is a problem that the D2D communication and the cellular communication (radio communication between a user terminal and a base station) are difficult to be compatible with each other.

Overview of Embodiment

[0026]A communication control method according to the embodiment is a communication control method used in a cellular mobile communication system that supports inter-terminal communication that is direct radio communication capable of being performed between user terminals in a state where a radio connection with a network is established, comprising: a step of determining, by the network, a method for assigning a radio resource in the inter-terminal communication in accordance with a characteristic of an application used in the inter-terminal communication.

[0027]In the embodiment, in the step of determining, the network may determine so as to assign to the inter-terminal communication, a radio resource shared with another inter-terminal communication when a traffic caused by the application is low in load and temporary.

[0028]In the embodiment, in the step of determining, the network may determine so as to assign to the inter-terminal communication, a dedicated ...

Description

TECHNICAL FIELD[0001]The present invention relates to a communication control method and a base station, which are used in a cellular mobile communication system supporting D2D communication.BACKGROUND ART[0002]In 3GPP (3rd Generation Partnership Project) which is a project aiming to standardize a cellular mobile communication system, the introduction of Device to Device (D2D) communication is discussed as a new function after release 12 (see Non-Patent Document 1).[0003]In the D2D communication, a plurality of user terminals proximal to one another are able to perform direct communication with each other in the state where a radio connection with a network is established (in the state where synchronization is achieved).[0004]In addition, the D2D communication is also called Proximity Service communication.PRIOR ART DOCUMENTNon-Patent Document[0005]Non-Patent Document 1:3 GPP technical report “TR 22.803 V0.3.0” May 2012SUMMARY OF THE INVENTION[0006]However, the current 3GPP standard...
