Abstract
A connection of a hands-free apparatus to a cellular phone is established through a hands-free profile, and the connection of the hands-free apparatus to the cellular phone through the hands-free profile is switched from the cellular phone to another cellular phone when a data communication is triggered. Then, the hands-free apparatus establishes another connection to the cellular phone through a dial-up network profile so that a hands-free call by the hands-free apparatus is appropriately handled.
