Abstract

At least one of outbound call history data, inbound call history data, and phone book data is transferred to a handsfree apparatus for use in a vehicle at a predetermined timing for the purpose of obtaining near realtime update of the inbound/outbound call history data from a cellular phone. By utilizing simultaneous connection of HFP and PBAP, the handsfree apparatus establishes a Bluetooth communication with the cellular phone through HFP first, and then establishes another communication through PBAP simultaneously, for receiving the inbound call history data and the outbound call history data stored before establishing the Bluetooth communication from the cellular phone. The handsfree apparatus can thus be capable of placing a call by using the outbound call history data and the inbound call history data stored in a work memory after receiving those data.

Claims

1. A handsfree apparatus for use in a vehicle comprising:

a handsfree call protocol connection unit connecting a handsfree telephone call protocol that establishes a handsfree telephone call with a cellular telephone;

a data transfer protocol connection unit connecting, with the cellular telephone, a data transfer protocol that performs data transfer processing enabling reception of, from the cellular telephone, at least one of outbound call history data, inbound call history data, missed call history data and telephone book data stored in the cellular telephone; and

a control unit enabling automatic reception of the outbound call history data immediately after termination of an outbound call that has been placed from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit, if the outbound call from the cellular telephone is determined to have been placed by an operation on the cellular telephone while the handsfree call protocol connection unit is in a protocol connected condition of the handsfree telephone call protocol.

2. A handsfree apparatus according to claim 1, wherein the control unit, without an input from a user, automatically enables reception of the outbound call history data of the outbound call that has been placed from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit after the outbound call from the cellular telephone is determined to have been placed by an operation on the cellular telephone while the handsfree call protocol connection unit is in the protocol connected condition of the handsfree telephone call protocol.

3. The handsfree apparatus according to claim 1, wherein the control unit starts from the beginning, the reception of the outbound call history data from the cellular telephone by using the data transfer protocol after the outbound call from the cellular telephone which was determined to have been placed by the operation on the cellular telephone while the handsfree call protocol connection unit is in the protocol connected condition has been completed.

4. A handsfree apparatus for use in a vehicle comprising:

a handsfree call protocol connection unit connecting a handsfree telephone call protocol that establishes a handsfree telephone call with a cellular telephone;

a data transfer protocol connection unit connecting, with the cellular telephone, a data transfer protocol that performs data transfer processing enabling reception of, from the cellular telephone, at least one of outbound call history data, inbound call history data, missed call history data and telephone book data stored in the cellular telephone; and

a control unit enabling automatic reception of the outbound call history data immediately after termination of an outbound call that has been placed from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit, if the outbound call is determined to have been placed from the handsfree apparatus while the handsfree call protocol connection unit is in a protocol connected condition of the handsfree telephone call protocol.

5. The handsfree apparatus according to claim 4, wherein the control unit, without an input from a user, automatically enables reception of the outbound call history data of the outbound call that has been placed from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit after the outbound call is determined to have been placed form the handsfree apparatus while the handsfree call connection unit is in a protocol connected condition of the handsfree telephone call protocol.

6. The handsfree apparatus according to claim 4, wherein the control unit starts from the beginning, the reception of the outbound call history data from the cellular telephone by using the data transfer protocol after the outbound call from the cellular telephone which was determined to have been placed from the handsfree apparatus while the handsfree call protocol connection unit is in the protocol connected condition has been completed.

7. A handsfree apparatus for use in a vehicle comprising:

a handsfree call protocol connection unit connecting a handsfree telephone call protocol that establishes a handsfree telephone call with a cellular telephone;

a data transfer protocol connection unit connecting, with the cellular telephone, a data transfer protocol that performs data transfer processing enabling reception of, from the cellular telephone, at least one of outbound call history data, inbound call history data, missed call history data and telephone book data stored in the cellular telephone; and

a control unit enabling automatic reception of at least one of inbound call history data and missed call history data from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit, to acquire the at least one of the inbound call history data and the missed call history data immediately after the termination of an inbound call, if the handsfree call protocol connection unit has the inbound call in a protocol connected condition of the handsfree telephone call protocol.

8. The handsfree apparatus according to claim 7, wherein the control unit, without an input from a user, automatically enables the reception of at least one inbound call history data and missed call history data from the cellular telephone by using the data transfer protocol connected by the data transfer protocol connection unit after a detection of state transition of the handsfree call protocol connection unit from a first state of communication to a second state of communication, the first state is in a protocol connected condition and having an inbound call, and the second state that is different from having the inbound call due to an end of having the inbound call.

9. The handsfree apparatus according to claim 7, wherein the control unit starts from the beginning, the reception of at least one of the inbound call history data and the missed call data from the cellular telephone by using the data transfer protocol after the inbound call to the cellular telephone while the handsfree call protocol connection unit is in the protocol connected condition has been completed.

10. A handsfree apparatus for use in a vehicle comprising:

a data transfer protocol connection unit connecting, with the cellular telephone, a data transfer protocol that performs data transfer processing enabling reception of, from the cellular telephone, at least one of outbound call history data, inbound call history data, missed call history data and telephone book data stored in the cellular telephone; and

a control unit enabling automatic reception of at least one of outbound call history data, inbound call history data, missed call history data and telephone book data from the cellular telephone through performance of periodic data transfer at specified time periods by using the data transfer protocol connected by the data transfer protocol connection unit.

11. The handsfree apparatus according to claim 10, wherein the control unit automatically starts from the beginning, the reception of at least one of the outbound call history data, the inbound call history data, the missed call history data and the telephone book data from the cellular telephone through the performance of periodic data transfer by using the data transfer protocol while the handsfree call protocol unit is in a continuous protocol connected condition with the cellular telephone.
