Radio communication terminal, communication control apparatus, and communication control method
First Claim
1. A radio communication terminal capable of providing a communication application via a radio access network and providing a communication application through direct communication with another radio communication terminal without involving the radio access network, the radio communication terminal comprising:
- a call restriction reception unit configured to receive a call restriction from the radio access network, the call restriction restricting initiation of communication to the radio access network;
a direct communication determination unit configured to determine whether or not a communication application to be executed in the radio communication terminal is executable through direct communication with another radio communication terminal without involving the radio access network; and
a radio communication unit configured to execute direct communication based on a result of the determination by the direct communication determination unit,wherein;
the call restriction reception unit receives a call restriction containing configuration information on a communication environment necessary for direct communication,during restriction of initiation of communication to the radio access network, the radio communication unit executes direct communication with the other radio communication terminal based on the configuration information when the direct communication determination unit determines that the communication application is executable through direct communication,the call restriction reception unit receives the call restriction containing permission information indicating whether direct communication is permitted or not, andthe direct communication determination unit determines whether the communication application is executable through direct communication or not based on the permission information.

Abstract
Provided are a radio communication terminal, a communication control apparatus, and a communication control method capable of enhancing the possibility of providing a communication application through inter-terminal direct communication (D2D communication) even in a case where a call request cannot be accepted due to congestion on the network side. In a terminal 400A, a call restriction reception unit 420 receives a call restriction containing configuration information on a communication environment necessary for direct communication. During restriction of initiation of communication to the radio access network, a radio communication unit 440 executes direct communication with another radio communication terminal based on the configuration information if a direct communication determination unit 430 determines that a communication application is executable through direct communication.
