Description

Information synchronization method between mobile terminal, personal computer and personal information management server {PIMS DATA SYNCHRONIZATION METHOD BETWEEN MOBILE STATION, PERSONAL COMPUTER AND PIMS SERVER}

The present invention relates to a method of synchronizing information (PIMS data) between a mobile communication terminal, a personal computer, and a personal information management server. The present invention relates to a wireless application protocol (WAP) and a short-range data communication relay such as Bluetooth. The present invention relates to a PIM data synchronization method for maintaining uniform information (PIM data) among various devices storing PIM data such as a mobile phone, a personal computer, a PIM server, and the like.

In particular, the present invention, the mobile phone and personal computer has a Bluetooth module and uses the Bluetooth interface as WAP bearer (WDP bearer) of WAP, the personal computer has a PIM Application (PIM Application) and WAP Gateway (WAP Gateway) module on the Internet Is connected to a PIM server in a mobile communication terminal and a personal computer and a PIM server to synchronize the information between each device to maintain the unity of information between the mobile terminal and personal computer and personal information management server It relates to a method for synchronizing information.

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 for his or her personal information (PIM data) mounted on different devices, the mobile phone, personal computer, PIM server according to the above example.

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.

The present invention proposes a method of synchronizing personal information between three parties to maintain consistency and uniformity of personal information between a mobile phone, a personal computer, and a PIM server.

The present invention provides a PIM application program of a personal computer, a PIM application program, a PIM server, and a WAP stack in order to synchronize PIM data between a mobile phone, a personal computer and a PIM server, and a three-party mobile phone having PIM data, respectively. communication through the stack, and the synchronization agent installed in the personal computer communicates with the mobile phone's synchronization agent using the WAP standard and communicates with the PIM server using the Internet protocol, thereby enabling the mobile phone, the personal computer and the PIM server to communicate with each other. The present invention proposes a method for synchronizing information between a mobile communication terminal, a personal computer, and a personal information management server to store the latest three-dimensional PIM data as unified information in a storage space.

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 PIMS 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 PIMS server 303 located on the Internet, and for this HTTP connection request, the PIMS server 303 is the personal computer 302. An access response (ACK) is performed by using the HTTP to the synchronization agent (S7). The PIMS server 303 transmits the PIMS data that it owns 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 PIMS data of its own personal computer. Send to step 302 (S10).

The synchronization agent of the personal computer 302 compares the PIMS data from the PIMS server 303 and the PIMS data from the mobile phone 301 with each other, and stores its phone number storage space and calendar storage space as the most up-to-date items. Is updated (S11).

The personal computer 302 transmits the updated PIMS data to the PIMS server 303 (S12) and receives an acknowledgment (ACK) thereto (S13), and also the updated PIMS 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, the PIMS server 303, and the update of the PIMS data between the three parties and sharing (unification) of the updated PIMS data (unification) are made, the personal computer 302 is carried out by the cellular phone 301. Request the WAP connection termination (S16), and request the HTTP connection termination from the personal computer 302 to the PIMS server 303 (S17).

The PIMS 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 cellular phone 301, the personal computer 302, the PIMS server 303, update of personal information (telephone number or schedule information, etc.) between the three parties, 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.
