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 for connecting a handsfree telephone call protocol that establishes a handsfree telephone call with a cellular telephone;

a data transfer protocol connection unit for performing data transfer processing that enables reception of, from the cellular telephone, at least one of inbound call history data and missed call history data stored in the cellular telephone after performing an initial connection process of data transfer protocol with the cellular telephone; and

a control unit for restarting, from a beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit, to acquire one of the inbound call history data and the missed call history data of an inbound call, after shifting to a different communication condition from an inbound call receiving condition of the cellular telephone, if the cellular telephone has the inbound call in (a) a protocol connected condition of the handsfree telephone call protocol by the handsfree call protocol connection unit and (b) the initial connection process of the data transfer protocol by the data transfer protocol connection unit.

2. The handsfree apparatus according to claim 1, wherein the control unit, without an input from a user, automatically starts, from the beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit.

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

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

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

a control unit for restarting, from a beginning, the data transfer processing of the data transfer protocol by the data transfer protocol connection unit, to acquire one of the inbound call history data and the missed call history data of an inbound call, after shifting to a different communication condition from an inbound call receiving condition of the cellular telephone, if the cellular telephone has the inbound call in (a) a protocol connected condition of the handsfree telephone call protocol by the handsfree call protocol connection unit and (b) the data transfer by the data transfer protocol connection unit.

4. The handsfree apparatus according to claim 3, wherein the control unit, without an input from a user, automatically starts, from the beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit.

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

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

a data transfer protocol connection unit for performing data transfer processing that enables reception of, from the cellular telephone, a call history data including at least one of inbound call history data and missed call history data stored in the cellular telephone after performing an initial connection process of data transfer protocol with the cellular telephone; and

a control unit for restarting, from a beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit, to acquire the call history data of an inbound call, after shifting to a different communication condition from an inbound call receiving condition of the cellular telephone, if the cellular telephone has the inbound call in (a) a protocol connected condition of the handsfree telephone call protocol by the handsfree call protocol connection unit and (b) the initial connection process of the data transfer protocol by the data transfer protocol connection unit.

6. The handsfree apparatus according to claim 5, wherein the control unit, without an input from a user, automatically starts, from the beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit.

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

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

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

a control unit for restarting, from a beginning, the data transfer processing of the data transfer protocol by the data transfer protocol connection unit, to acquire the call history data of an inbound call, after shifting to a different communication condition from an inbound call receiving condition of the cellular telephone, if the cellular telephone has the inbound call in (a) a protocol connected condition of the handsfree telephone call protocol by the handsfree call protocol connection unit and (b) the data transfer by the data transfer protocol connection unit.

8. The handsfree apparatus according to claim 7, wherein the control unit, without an input from a user, automatically starts, from the beginning, the initial connection process of the data transfer protocol by the data transfer protocol connection unit.
