Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Prior to the description of the present invention, when a customer using a mobile communication terminal, for example, a WAP supporting terminal, uses an address book, only one address book is inputted without distinguishing between the address book of the mobile communication terminal and the personal information server. It is characterized by being synchronized.

1 is a schematic block diagram of a mobile communication terminal and a personal information server for carrying out the method according to the present invention. The mobile communication terminal 10, the wireless network 20, the personal information server 30 and the Internet network ( 40).

As shown, the mobile communication terminal 10 is a wireless mobile terminal (eg, cellular phone, personal mobile communication (PCS) that can be connected to the wireless network 20 through a mobile communication control means, that is, a base station (not shown) or the like. , PDA, IMT-2000, etc.), connected to a personal information server () to be described later through the wireless network 20, and address book information in the personal information server 30 to describe address book information in the mobile communication terminal 10 described later. Synchronize with. That is, the mobile communication terminal 10 is provided with a function for registering, modifying and deleting address book information according to the present invention, and the input of such address book information is performed by a key input means existing on a conventional mobile communication terminal. As can be, a detailed description thereof will be omitted.

The personal information server 30 is connected to a terminal device (not shown), for example, a personal computer (Personal Computer) and the Internet network 40, the address book information data input through the PC and the above-described mobile communication terminal 10 Manage the address book information input through. That is, the personal information server 30 synchronizes the address book information data input through the PC with the address book information data in the mobile communication terminal 10 described above.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figures 2 and 3 attached to the address book synchronization process according to a preferred embodiment of the present invention will be described in detail.

Prior to the description, the present invention manages an entry ID, an information change flag, and time information in the address book information field of the mobile communication terminal 10 and the address book information field of the personal information server 30, respectively. It features.

This entry ID serves as a key of the address book record. The same address book information of the mobile communication terminal 10 and the personal information server 30 has the same entry ID. In addition, the information change flag is generated with a different value according to each case such as address book information generation, modification, deletion, etc., and stores the occurrence time of changing the address book information in the mobile communication terminal 10 and the personal information server 30, respectively. do. In this case, the reason for managing the occurrence time is that when the address book information of the mobile communication terminal 10 and the personal information server 30 are changed for the same address book information, the occurrence time at the time of performing the address book synchronization is applied as the latest address book information. To do that.

2 is a flowchart illustrating the address book synchronization process, and illustrates a synchronization process when the address book information is changed in the mobile communication terminal 10.

First, in step S200, the mobile communication terminal 10 determines whether registration of predetermined address book information is requested.

As a result of the determination in step S200, if the predetermined address book information registration is requested, the mobile communication terminal 10 proceeds to step S202 and gives an already assigned entry ID in the mobile communication terminal 10, and then in step S204. Proceed to assign address value change flag value.

Thereafter, in step S206, the mobile communication terminal 10 stores the occurrence time when the address book information is changed, and proceeds to step S208 to synchronize with the address book information in the personal information server 30. That is, as illustrated in the tables of FIGS. 4A and 4B, assuming that address book information A and B are registered in the mobile communication terminal 10 and no address book information exists in the personal information server 30. When the address book synchronization "is executed, it can be seen that address book information A and B of the mobile communication terminal 10 is copied and stored in the personal information server 30. Further, assuming that address book information A and B is registered in the mobile communication terminal 10 and address book information B, C and D are registered in the personal information server 30, if "Address Book Synchronization" is executed, The address book information of A, B, C, D is stored in the communication terminal 10, and the address book information of A, B, C, D is also stored in the personal information server 30 to maintain synchronization.

Meanwhile, in step S210, the mobile communication terminal 10 determines whether address book information modification or address book information deletion is requested by a user's input.

As a result of the determination of step S210, when the address book information is corrected or the address book information is requested, the process proceeds to step S204 described above to perform the address book synchronization between the mobile communication terminal 10 and the personal information server 30. That is, as illustrated in FIGS. 4A and 4B, when modifying address book information, the address book information A and B is synchronized with the mobile communication terminal 10 and the personal information server 30, and then the personal information server 30 is synchronized with the personal information server 30. When the address book information of B is corrected by the mobile communication terminal 10 and then "Address Book Synchronization" is executed, the address book information of the mobile communication terminal 10 and the personal information server 30 are stored and synchronized as the modified address book information of B, respectively. do. In addition, when the address book information is deleted, the address book information of B is deleted from the personal information server 30 while the address book information of persons A and B are stored in the mobile communication terminal 10 and the personal information server 30, respectively. Afterwards, if the address book synchronization is executed, the mobile communication terminal 10 and the personal information server 30 respectively store only the address book information of A from which the information of B is deleted.

On the other hand, Figure 3 is a flow chart of the address book synchronization process according to a preferred embodiment of the present invention, a view showing a synchronization process when changing the address book information in the personal information server 30.

When the address book information is changed in the personal information server 30, unlike the address book information change in the mobile communication terminal 10 described above, the information is transferred to the mobile communication terminal 10 without immediately assigning an entry ID. The entry ID usable in the communication terminal 10 is allocated to the personal information server 30 (S302), (S304), and (S306). The rest of the process is the same as the address book synchronization process of FIG. 2 described above, and a detailed description thereof will be omitted.

In addition, in the address book synchronization method according to the present invention, the number of storage of address book information is limited for each mobile communication terminal. In the case of a personal information server, the number of address book information of the personal information server can be stored. If more than the number of storage of the mobile communication terminal, it will be possible to synchronize the address book up to the number of storage of the mobile communication terminal.

Therefore, in the present invention, if only one address book is inputted without distinguishing the address book of the mobile communication terminal and the personal information server, both address books are automatically synchronized to provide management efficiency and convenience, and also serve as a backup address book data. You can enjoy the effect.
