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 by establishing a wireless connection with a cellular phone, the cellular phone storing incoming call history data indicating a source telephone number of an incoming call, and outgoing call history data indicating a destination telephone number of an outgoing call,
the handsfree apparatus comprising: a control section configured to perform a communication using a transfer protocol for realizing transfer of the incoming call history data and the outgoing call history data, which are stored in the cellular phone prior to the wireless connection between the handsfree apparatus and the cellular phone, when the cellular phone exists in a wireless connection area; a communication section configured to receive the incoming call history data and the outgoing call history data from the cellular phone via the communication using the transfer protocol; a data storage section configured to store the outgoing call history data and the incoming call history data, which are received; and a display section configured to display the outgoing call history data and the incoming call history data, wherein when all history data including the incoming call history data and the outgoing history data are displayed in the display section,
the control section
sorts dates and times included in both the outgoing call history data and the incoming call history data, in order of date and time, andcauses the display section to display all the history data in the order of dates and times.
