In-vehicle wireless communications device
First Claim
1. An in-vehicle wireless communications device, comprising:
- a wireless communications unit powered by an in-vehicle battery to receive an incoming signal from a wireless communications network;
a control unit enabled to execute an incoming process to an incoming signal received by the wireless communications unit;
a discharge determining unit for determining whether the in-vehicle battery is being discharged; and
an incoming signal type determining unit for determining a type of an incoming signal received by the wireless communications unit;
wherein when an incoming signal is received by the wireless communications unit and the battery is determined to be being discharged, the control unit executes no incoming process to the received incoming signal when the received incoming signal is determined to be not a specific incoming signal, whereas the control unit executes an incoming process to the received incoming signal when the received incoming signal is determined to be the specific incoming signal.

Abstract
An in-vehicle wireless communications device receives an incoming signal via a wireless communications unit from the wireless communications network. When the in-vehicle battery is being discharged, the type of the incoming signal is determined. When the incoming signal is for a voice call, a packet communications, or a TV phone, no incoming process for the received incoming signal takes place. In contrast, when the incoming signal received by the wireless communications circuit from the wireless communications network is an incoming signal for a short message service that becomes a trigger for vehicle remote monitoring or vehicle remote control, an incoming process to the received incoming signal is executed.
