Patent Images
1. An in-vehicle handsfree apparatus comprising:
- a handsfree protocol connecting section configured to connect a handsfree communication protocol with a cellular phone compliant with a handsfree communication protocol for executing a handsfree communication using the cellular phone;
a data transfer protocol connecting section configured to connect a data transfer protocol with a cellular phone compliant with a data transfer protocol for executing a data transfer from the cellular phone; and
a control section configured,in case that a connection request of a data transfer protocol with a second cellular phone among a plurality of cellular phones occurs when a handsfree communication protocol is connected with a first cellular phone among the plurality of cellular phones,to once disconnect the handsfree communication protocol which has been connected with the first cellular phone and then connect a data transfer protocol with the second cellular phone using the data transfer protocol connecting section.

Abstract
While an in-vehicle handsfree apparatus establishes a connection of a handsfree profile (HFP) with a first cellular phone, an audio visual profile (AVP) connection with a second cellular phone is requested. In such a case, the handsfree apparatus once cuts the HFP connection with the first cellular phone, and then connects the AVP with the second cellular phone. This can prevent the handsfree apparatus from connecting the HFP with the first and second cellular phones at the same time.

4. A method for performing a data transfer in an in-vehicle handsfree apparatus capable of connecting a handsfree communication protocol simultaneously with a first cellular phone and a second cellular phone, the method comprising:
-
connecting a handsfree communication protocol with the first cellular phone for executing a handsfree communication; receiving a connection request of a data transfer protocol from the second cellular phone, which occurs in response to a user operation to instruct the second cellular phone to perform a data transfer to the in-vehicle handsfree apparatus; disconnecting the handsfree communication protocol with the first cellular phone; and connecting the data transfer protocol with the second cellular phone.
