It also makes it easier for drivers, car companies and phone manufacturers to use Bluetooth wireless technology.

PBAP is a vehicle hands-free laying profile. You can provide the driver with a number in your phonebook. Use is very simple. Just download the phone book of your phone or PDA (Personal Digital Assistant) to browse.

As shown, the server and the client perform settings for data communication using Bluetooth with each other. Start sending the phone book from the server to the client. At this time, an interrupt condition occurs in the server while the phone book is being transmitted. For example, exceptional situations may occur, such as when a call is received or when a user needs to make a call. In addition, it may be necessary to change, add, or delete phonebook information while the phonebook is being transmitted. In this case, the transfer is aborted and the operation performed in the exceptional situation. For example, if a call arrives during transmission, the call is performed. At this time, it sends a query message to the client whether to pause but continue receiving when the exception is over. When receiving a message to continue receiving, transmits the change information stored in the server to the client.

6 is a flowchart illustrating a process of a data transmission method according to the present invention.

Environment setting for Bluetooth communication is preceded between the transmitting terminal (server) and the receiving terminal (client). When the environment setting is completed, the server starts to transmit the phone book information to the client (S601).

When a call is received or when an interrupt situation occurs in which a user of a transmitting terminal attempts to make a call or needs to add, change, or delete information related to a phone book (S602), an exception handling function in advance ( change tracking) (S603).

Presetting may be performed for each of the server and the client. That is, as shown in Fig. 7, it can be set for exception processing. Such a setting may be made in a terminal environment setting or a wireless communication environment setting among menus of the terminal, and may also be made in a convenience function menu in some cases. The setting method may be performed differently according to the application program of each terminal. If not, the user's selection may be received using the pop-up screen as shown in FIG. 8. Like the preset, this operation is possible at both the server and the client (S604).

It is determined whether the user's selection by the preset or the pop-up screen is using an exception tracking function (change tracking) (S605). If the exception handling function is set or selected not to be used, the transmission of the telephone book is stopped (S606-2), and the operation according to the interrupt situation is implemented. That is, the current transmission operation is interrupted and a call is made or an operation such as addition / change / deletion of a phone book is performed (S607-2).

If you choose to use exception handling for pre-set or pop-up screens, stop the transfer first. The operation that is being transmitted is interrupted once (S606-1), and a call is received or sent or a change / add / delete of the phone book is performed (S607-1).

After the operation is completed, as shown in FIG. 9, a query message is transmitted to the counterpart terminal (client) as to whether to receive the information about the change and the missing work (cancellation information which is canceled and not received) (S608).

If it does not receive a response from the client to continue receiving all the processing, and if the reception continues to receive (S609), if a change is made to the existing transmission content is stored (S610), and retransmission for the portion It is performed to match the information of the other terminal. When all reception operations are completed, the client terminal displays a notification screen for completion of reception as shown in FIG. 10 (S611).

In the above embodiment, the transmission of the message to the client asking whether to continue receiving after interrupting the transmission and performing interrupt processing first is described as an example. However, the message may be sent to the client along with the interruption of the transmission. have.

In addition, in this description, a case where an exception occurs on the server side is described, but the same case may occur on the client side. In other words, a call may be received or originated while receiving a phone book from the server. In this case, since the receiving operation cannot continue on the client side, a guide message for such a situation is transmitted to the server, and the call is performed. After the call is terminated, the final received information may be transmitted to the server to receive subsequent data.
