In-vehicle handsfree apparatus
First Claim
1. An in-vehicle handsfree apparatus comprising:
- a handsfree connection section configured toestablish a handsfree communication protocol connection with a cellular phone having a function to(i) switch a call link, which is in a calling state, to a suspending state when a suspension request signal is issued and(ii) switch a call link, which is in an incoming call receiving state, to a calling state when an incoming call response request signal is issued;
a control section configured toperform a notice of a different phone interruption incoming call, the notice of the different phone interruption incoming call being performed in case, of a plurality of cellular phones with which the handsfree connection section establishes a handsfree communication protocol connection simultaneously, a second cellular phone receives an incoming call when a first cellular phone is in a calling state; and
a different phone interruption incoming call response operation section configured for a user to perform a response operation to the different phone interruption incoming call in response to the notice of the different phone interruption incoming call,the control section being further configured to,when the user performs the response operation to the difference phone interruption incoming call,(i) issue a suspension request signal to the first cellular phone in the calling state and an incoming call response request signal to the second cellular phone in the incoming call receiving state and(ii) switch a connection partner of a call sound path from the first cellular phone to the second cellular phone, the call sound path via which the handsfree connection section carries a transmission sound and a reception sound.

Abstract
An in-vehicle handsfree apparatus establishes a handsfree profile connection with a first cellular phone and a second cellular phone simultaneously. It is assumed that while the first cellular phone is in a calling state, the second cellular phone receives an incoming call. When a user operates a response to the second cellular phone in the incoming call receiving state, a suspension request signal is transmitted to the first cellular phone in the calling state to thereby switch the call link of the first cellular phone to a suspending state. In contrast, an incoming call response request signal is transmitted to the second cellular phone to thereby switch the call link of the second cellular phone from the incoming call receiving state to a calling state. The connection partner of a call sound path is changed from the first cellular phone to the second cellular phone.

4. A method for switching call links of a first cellular phone and a second cellular phone included in a plurality of cellular phones with which an in-vehicle handsfree apparatus simultaneously establishes a handsfree communication protocol connection, the method comprising:
-
performing a notice when a different phone interruption incoming call takes place in case the second cellular phone receives an incoming call when the first cellular phone is in a calling state; receiving a response operation to the different phone interruption incoming call in response to the notice of the different phone interruption incoming call; issuing, in response to the received response operation, (i) a suspension request signal to the first cellular phone to thereby switch a call link of the first cellular phone, which is in a calling state, to a suspending state, and (ii) an incoming call response request signal to the second cellular phone to thereby switch a call link of the second cellular phone, which is in an incoming call receiving state, to a calling state; and switching, in response to the received response operation, from the first cellular phone to the second cellular phone a connection partner of a call sound path via which a transmission sound and a reception sound is carried in the calling state.
