ABSTRACT:
While a handsfree device being multi-profile compatible is maintaining a connection for a handsfree profile (HFP) with a mobile phone handset, the handsfree device cuts off the connection for the HFP based on a user's operation. After cutting off, the handsfree device establishes a connection for a dial-up network profile (DUN), and subsequently transmits a request for a connection for the HFP while maintaining the connection for the DUN. Subsequently, the handsfree device determines whether the handset is multi-profile compatible according to the response to the request from the handset. Based on the determination that the handset is multi-profile compatible, the handsfree device executes the processes for the HFP while maintaining the connection for the DUN.
