Abstract

Disclosed are a method and an apparatus for causing a vehicle Bluetooth handsfree device to be automatically connected to a mobile communication terminal. When the Bluetooth handsfree device is powered up, paging is performed for all mobile communication terminals registered in a handsfree user list stored in the Bluetooth handsfree device. If the number of terminals paged is one, Bluetooth-connection to a corresponding mobile communication terminal is performed. If the number of terminals paged is two or more, a list of paged terminals is provided to a user, and Bluetooth-connection to a selected mobile communication terminal is performed. In this way, even when multiple passengers are in a vehicle, Bluetooth-connection to a driver'"'"'s mobile communication terminal can be automatically performed. Further, it is also possible to automatically perform Bluetooth-connection to a mobile communication terminal having not been most recently connected to a Bluetooth handsfree device.

Claims

1. A method for automatically performing by a Bluetooth handsfree device mounted in a vehicle Bluetooth-connection to a mobile communication terminal equipped with a Bluetooth module, comprising:

performing Bluetooth paging for registered mobile communication terminals by using previously stored connection information of the mobile communication terminals previously Bluetooth-connected to the Bluetooth handsfree device when the Bluetooth handsfree device is powered up;

determining the number of Bluetooth connectable terminals by performing Bluetooth paging;

if only one mobile communication terminal has been paged as a result of the paging, performing Bluetooth-connection to the only one mobile communication terminal;

providing a list of paged mobile communication terminals if two or more registered mobile communication terminals have been paged; and

performing Bluetooth-connection to a mobile communication terminal selected from the list by a user of the Bluetooth handsfree device.

2. The method as claimed in claim 1, wherein the connection information comprises Bluetooth device addresses corresponding to each registered mobile communication terminal, user names of said each registered mobile communication terminal, and authentication keys.

3. The method as claimed in claim 2, further comprising, if there is no paged mobile communication terminal as a result of the paging, notifying the user of failure of the Bluetooth-connection.

4. A Bluetooth handsfree device mounted in a vehicle, comprising:

a Bluetooth module;

a display unit;

a speaker;

a microphone; and

a controller for controlling the Bluetooth module to perform paging for all registered mobile communication terminals previously Bluetooth-connected to the Bluetooth handsfree device by using previously stored connection information of the registered mobile communication terminals, determining the number of Bluetooth connectable terminals by performing Bluetooth paging, if only one mobile communication terminal has been paged as a result of the paging, the controller performs Bluetooth-connection to the only one mobile communication terminal, providing a list of paged mobile communication terminals if two or more mobile communication terminals have been paged as a result of the paging, and performing Bluetooth-connection to a mobile communication terminal selected from the list by a user of the Bluetooth handsfree device.

5. The Bluetooth handsfree device as claimed in claim 4, wherein the connection information includes Bluetooth device addresses corresponding to each registered mobile communication terminal, user names of said each registered mobile communication terminal, and authentication keys.

6. The Bluetooth handsfree device as claimed in claim 5, wherein, if there is no paged mobile communication terminal as a result of the paging, the controller notifies the user of failure of the Bluetooth-connection.
