Summary:Plural terminal devices (10a,10b) are arranged under a relay apparatus (20). The relay apparatus (20) includes a mobile communication network connection unit (25), a packet switching network connection unit (26), and an emergency call determination unit (24). The emergency call determination unit determines whether or not the calls originated from the terminal devices are emergency calls, and when the calls are the emergency calls, connects the emergency calls to the mobile communication network connection unit (25). When the calls are the emergency calls, the mobile communication network connection unit connects the emergency calls to the mobile communication network (30) by issuing thereto a notice on an identification number of the relay apparatus, the identification number being stored in an IC card (90) attached to the relay apparatus.
