    摘要: 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.
