Abstract:
1. A vehicle terminal apparatus comprising: a wireless communication device for performing a short range wireless communication, wherein the vehicle terminal apparatus connects the wireless communication device to a portable terminal that enables a voice call and the short range wireless communication through a communication network; a connection monitoring unit for monitoring a disconnection of a communication link between the wireless communication device and the portable terminal, wherein the connection monitoring unit considers an abnormal disconnection of the communication link as a link loss, the connection monitoring unit considers a disconnection of the communication link by a disconnection process by the wireless communication device as a first disconnection, and the connection monitoring unit considers a disconnection of the communication link by a disconnection process by the portable terminal as a second disconnection; and a connection condition determination unit for determining a wireless connection condition of the wireless communication device based on a disconnection reason that accounts for a reason for disconnection and a pre-disconnection call condition that is a call condition of the portable terminal immediately before the disconnection when the disconnection of the communication link is detected by the connection monitoring unit.
