Wireless communications system, base station, and terminal

A base station of a wireless communications system including a packet core network, and a wireless access network including the base station and a terminal, the base station comprising:

• a communications unit configured to perform communication with the packet core network and detect a failure in a connection between the packet core network and the base station;
• and
• a control unit configured to be capable of performing a process related to a proximity-based communications service between a plurality of terminals and when a failure is detected by the communications unit, the control unit causes execution of proximity-based communication between the plurality of terminals by performing authentication and authorization of communication with a terminal connected to the base station among the plurality of terminals by using the process related to the proximity-based communications service.

A terminal of a wireless communications system including a packet core network, and a wireless access network including a base station and the terminal, the terminal comprising:

• a communications unit configured to communicate with another terminal;
• and
• a control unit configured to control communication by the communications unit based on a control signal from the base station configured to be capable of performing a process related to a proximity-based communications service between a plurality of terminals and when a failure in a connection between the base station and the packet core network occurs, the base station causes execution of proximity-based communication between the plurality of terminals by performing authentication and authorization of communication with a terminal connected to the base station among the plurality of terminals by using the process related to the proximity-based communications service.
