The present invention relates to a wireless application protocol (WAP) and a short-range data communication relay. A method of synchronizing PIM data using Bluetooth, such as a mobile phone, a personal computer, a personal information manager (PIM) server, and the like to maintain unified information (PIM data) among devices that store PIM data. will be.

In particular, the present invention, the mobile phone and personal computer has a Bluetooth module and uses the Bluetooth interface as WAP (WDP (Wireless Datagram Protocol) bearer) of WAP, PIM application (PIM Application) and WAP Gateway (WAP Gateway) A mobile communication terminal and a personal computer having a module connected to a PIM server on the Internet to synchronize information between the mobile phone, the personal computer and the PIM server, thereby maintaining the unity of information held between the respective devices; A method for synchronizing information of a personal information management server.

With the development of communication technology and the proliferation of personal computers, most users use at least mobile phones and personal computers, and mobile phones and personal computers have a phone book management function, a schedule management function, and a memo function of various personal information. It is equipped with convenient functions to manage various and rich forms of personal information. Such personal information may be managed by a personal information manager (PIM server) according to a user environment in which a user accesses the Internet using a terminal, obtains necessary information on the Internet, and sends and receives e-mails.

Therefore, the user has a need for a unified information management on his / her personal information (PIM data) mounted on different devices, according to the above example, a mobile phone, a personal computer, or a PIM server.

However, until now, PIM information synchronization has been mixed with two methods, a synchronization technology between a mobile phone and a computer, or a synchronization technology between a mobile phone and a PIM server.

First, as shown in FIG. 1, the synchronization between the mobile phone and the personal computer is mainly performed by the application program of the mobile phone and the personal computer using the RS232C serial interface, and the synchronization between the mobile phone and the PIM server is shown in FIG. Similarly, WAP (Wireless Application Protocol) is used to synchronize information between a PIM server (mainly provided by a mobile operator) and a mobile phone on the Internet.

That is, according to Fig. 1, the personal information synchronization between the conventional mobile phone 101 and the personal computer 102 is connected to each other using the RS232C serial interface 103, and the PIM management application program operating on the personal computer 102 is used. The synchronization of information between the mobile phone 101 is made, and according to FIG. 2, the personal information synchronization between the conventional mobile phone 201 and the PIM server 202 is supported by the mobile communication service provider through the wireless network 203. The gateway 204 is used to connect the mobile phone 201 to the PIM server 202.

In the former case, however, the PIM server is excluded because only the synchronization of information between a mobile phone and a personal computer can be achieved using the RS232C serial interface. In the latter case, personal computers are excluded because only the synchronization of information between the cellular phone and the PIM server can be achieved using a wireless network (WAP gateway).

Therefore, from the user's point of view, in order to achieve personal information synchronization between the devices, a mobile phone and a personal computer, a mobile phone and a PIM server, and the inconvenience of having to attempt two synchronizations follow. In addition, since information is exchanged between the personal computer and the PIM server via a mobile phone, the PIM information capacity of the personal computer is limited according to the information storage capacity of the mobile phone.

First, the synchronization operation is started by the request of the user of the mobile phone 301 or by the push from the PIM server 303 (S1 or S1-1).

In the case of the request of the user of the mobile phone 301, the mobile phone 301 and the personal computer 302 must be in the connection state of the sub network using Bluetooth as described with reference to Figs. There is a Bluetooth connection request from the personal computer 302 to the personal computer 302 (S2), and the Bluetooth connection response from the personal computer 302 is transmitted to the mobile phone 301 in response to the request (S3).

If the PIM server 303 is started by the push of the PIM server 303, the PIM server 303 follows a sync request by PUSH PIM server (S1-1).

As described above, when the Bluetooth connection is established between the mobile phone 301 and the personal computer 302, the mobile phone 301 requests the WAP connection request of the URL request in the form of Sync: //xxx.xxx.xxx.xxx/phonebook described in FIG. Together with the personal computer 302 (S4).

As such, the PIM application (program) of the personal computer 302 having received the synchronization URL executes a synchronization agent operating on the WAP protocol (S5). Accordingly, the synchronization agent of the personal computer 302 loads the relevant database from the phone book storage space and the calendar storage space into a predetermined storage space for updating the PIM data as described in FIG.

In a next step S6, the synchronization agent of the personal computer 302 executes an HTTP connection request to the PIM server 303 located on the Internet, and for this HTTP connection request, the PIM server 303 is connected to the personal computer 302. An access response (ACK) is performed by using the HTTP to the synchronization agent (S7). The PIM server 303 then transmits its own PIM data to the personal computer 302.

In a next step S9, the synchronization agent of the personal computer 302 performs a WAP access response (ACK) to the mobile phone 301, and the mobile phone 301 uses the WAP connection to display the PIM data of the personal computer. Send to step 302 (S10).

The synchronization agent of the personal computer 302 compares the PIM data from the PIM server 303 and the PIM data from the mobile phone 301 with each other and includes their phone number storage space and calendar storage space as the latest items. Is updated (S11).

The personal computer 302 transmits the updated PIM data to the PIM server 303 (S12) and receives an acknowledgment (ACK) for it (S13), and also the updated PIM data to the mobile phone 301. It transmits (S14), and receives a response (ACK) for this (S15).

In this manner, after the cellular phone 301, the personal computer 302 and the PIM server 303, update the PIM data between the three parties and share the updated PIM data (unification), the personal computer 302 is performed on the cellular phone 301. Request the WAP connection termination (S16), and request the HTTP connection termination from the personal computer 302 to the PIM server 303 (S17).

The PIM server 303 performs a response to the HTTP connection termination request (S18), and the personal computer 302 performs a response to the WAP connection termination request to the mobile phone 301 (S19).

As a result, the mobile phone 301, the personal computer 302, the PIM server 303, the update of the three-person personal information (phone number or schedule information, etc.) and the unification are maintained, and the mobile communication terminal according to the present invention is maintained. The information synchronization procedure of the personal computer and the personal information management server is completed.

According to the method for synchronizing information between the mobile communication terminal, the personal computer and the personal information management server of the present invention, the user can keep the PIM data of his or her personal computer the same as the mobile phone and the PIM server, and also use Bluetooth as the WAP bearer. By doing so, there is an advantage in that the PIM data can be synchronized without going through the mobile operator's network.
