Communication control method and base station

Abstract

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, comprises 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.

1 . 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.   
     
     
         2 . The communication control method according to  claim 1 , wherein, in the step of determining, the network determines 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. 
     
     
         3 . The communication control method according to  claim 1 , wherein, in the step of determining, the network determines so as to assign to the inter-terminal communication, a dedicated radio resource periodically when a traffic caused by the application is high in load and continuous. 
     
     
         4 . The communication control method according to  claim 1 , wherein, in the step of determining, the network determines so as to assign to the inter-terminal communication periodically with enabling repeated transmission, a dedicated radio resource when a traffic caused by the application is high in load and continuous and requires low delay. 
     
     
         5 . A base station used in a 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 processor that performs a process for determining 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.
