In-vehicle handsfree apparatus and data transfer method

摘要

An in-vehicle navigation apparatus with a handsfree function establishes a Bluetooth communication link with a cellular phone. When receiving from the cellular phone outgoing call history data and incoming call history data, which were stored in the cellular phone before establishing the Bluetooth communication link, the in-vehicle navigation apparatus stores, in a work memory, the received outgoing call history data and the received incoming call history data, equally to, of the navigation apparatus itself, outgoing call history data and incoming call history data. An outgoing call operation then becomes possible using outgoing call history data and incoming call history data, which are stored in the work memory.

主权项

1. An in-vehicle handsfree apparatus allowing a handsfree phone call using a handsfree protocol by establishing a connection with a cellular phone, the cellular phone storing outgoing call history data indicating a destination telephone number to which a phone call was transmitted,
the handsfree apparatus comprising: a control section
connecting communication with the cellular phone with a transfer protocol for realizing transfer of the outgoing call history data stored in the cellular phone before establishing the connection between the handsfree apparatus and the cellular phone,receiving the outgoing call history data from the cellular phone using the transfer protocol, anddisconnecting, after receiving the outgoing call history data, the communication using the transfer protocol; a display section; and an operation section performing an outgoing call instruction to the cellular phone, wherein in cases where, after receiving the outgoing history data from the cellular phone using the transfer protocol and disconnecting the communication using the transfer protocol, an outgoing call instruction is performed by the operation section under a communication state using the handsfree protocol taking place for realizing the handsfree phone call, the control section is configured to cause the display section to display self outgoing call history data indicating a telephone number of a destination in the outgoing call instruction, as being newer in an outgoing call date and time than the outgoing call history data when a display demand of outgoing call history data occurs after the outgoing call instruction was performed by the operation section.
