The present invention relates to a method for synchronizing an address book of a mobile communication terminal user, and more particularly, in synchronizing an address book stored in a mobile communication terminal with an address book of a mobile communication terminal user previously stored in an address book management server. An address book is transmitted and received between a server and the mobile communication terminal using a wCard including a speed dial number, and the address book management server sends a name and a phone number to the address book received from the mobile communication terminal and the address book of the corresponding user. The present invention relates to a method for synchronizing an address book of a mobile communication terminal user, in which duplicate address book entries are compared with each other and arranged according to a modification date.

Many devices (e.g. computers, mobile phones, PDAs, electronic organizers, etc.) that can be easily seen in everyday life include information such as the names of others, mobile / home / work phone numbers, e-mail addresses, etc. ("address book"). It is equipped with an address book program that can manage "."

For example, a user enters a company and manages work contacts in an address book stored on a computer, and fills in e-mails received through a mail sending program (e.g., Microsoft's Outlook, Outlook-Express, etc.). Integrated contacts, email addresses, etc. into the above address book. Meanwhile, the above user manages the contact information of another person in the address book stored in the mobile communication terminal while on the outside, and provides personal contact information through instant messenger (e.g., Nate-on messenger of SK Telecom Co., Ltd.) Manage it by listing it in the address book.

As described above, an address book of a specific user is distributed and managed in each of a personal computer, a mobile communication terminal, and an address book management server. The user's address book, especially the address book stored in the mobile terminal and the address book stored in the address book management server, can be integrated so that the user can manage his / her own address book distributed in several places (that is, keep all address books the same). The technology of synchronizing with this has emerged. The conventional address book synchronization method will now be described.

When the user requests to load or send a mobile terminal address book through a website or an instant messenger provided by the address book management server, the address book management server transmits a callback URL short message to the corresponding mobile terminal. Accordingly, when the user presses the call button, the mobile communication terminal accesses the corresponding URL through the wireless Internet, and downloads the address book previously stored on the server from the address book management server or is stored on the mobile communication terminal to the address book management server. Upload your address book. By such an address book import / send operation, the address book stored in the address book management server and the mobile communication terminal are coincident with each other.

Meanwhile, in the aforementioned conventional address book synchronization method, an address book is exchanged between the address book management server and the mobile communication terminal using wCards. For example, since the data formats used in the address book management program implemented in the address book management server and the address book management program implemented in the mobile communication terminal are different from each other, address book compatibility between the server and the terminal cannot be properly performed. Thus, by using an address book synchronization application pre-loaded between the address book management server and the mobile communication terminal to insert their own address book stored in the DB (or memory) to the wCard to exchange each other.

More specifically, wCard is a Wi-Fi platform defined by extending the necessary information from the address book of the terminal based on vCard, the standard business card data format. It is address book format. On the other hand, the Wi-Fi platform is mounted and used as a standard middleware in the mobile communication terminal, and provides a technical environment and application software that allows the address book synchronization application to be executed in the mobile communication terminal.

However, when the address book management server synchronizes the address book received from the mobile communication terminal or when the mobile communication terminal synchronizes the address book received from the address book management server, the address book is sorted according to an index. Because of this, address book entries having the same name and / or the same telephone number have different indices and thus are treated as separate address book entries, so that duplicate address books are also synchronized and stored in each of the address book management server and the mobile terminal. It's a pity. Such a duplicate address book causes a waste of resources [storage space] of the mobile communication terminal and the address book management server, and in particular, has a problem in that the user has to delete the duplicate address book manually.

In the conventional address book synchronization method, a speed dial number is not defined in a wCard that is exchanged between an address book management server and a mobile communication terminal. As a result, the speed dial number (usually the speed dial number is set in the address book) set by the user is not synchronized with the address book management server. There is a hassle that the user has to reset the speed dial number directly to the new mobile communication terminal because it does not give down to the new mobile communication terminal.

The present invention has been proposed to solve the above problems and to meet the above requirements, in synchronizing the address book stored in the mobile communication terminal with the address book of the mobile communication terminal user previously stored in the address book management server. An address book is transmitted and received between the address book management server and the mobile communication terminal using a wCard including a speed dial number, and the address book management server uses a name and address book for the address book received from the mobile communication terminal and the address book of the corresponding user. It is an object of the present invention to provide a method for synchronizing an address book of a mobile communication terminal user by comparing phone numbers with each other and arranging duplicate address book entries according to modification dates.

The method of the present invention for achieving the above object, in the method of synchronizing the address book of the mobile communication terminal user in the address book management server, when the user is requested to synchronize the mobile terminal A address book to the mobile terminal B address book A first step of requesting an address book upload from the mobile communication terminal A and receiving an address book from the mobile communication terminal A in response thereto; A second step of aligning each item of the address book received from the mobile communication terminal A with each item of the user's address book previously stored; A third step of arranging each address book item having a duplicate name or / and phone number with reference to each modified date and time in a state in which the names, telephone numbers, and modified date and time of each sorted address book item are checked; And a fourth step of requesting an address book download to the mobile communication terminal B and transmitting the generated address book to the mobile communication terminal B in response to the address book being generated based on the arranged address book items.

Meanwhile, another method of the present invention provides a method of synchronizing an address book of a user in a mobile communication terminal, comprising: a first step of sorting each item of an address book included in the wCard when receiving a wCard from an address book management server; A second step of organizing each address book item having a duplicate name or / and phone number with reference to each modified date and time in a state in which the name, phone number, and modified date and time of each sorted address book item are checked; And a third step of storing the summarized address book items in a terminal phone book.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

1 is a configuration of a preferred embodiment of a communication network to which the present invention is applied.

As shown in FIG. 1, a communication network to which the present invention is applied includes a computer 10, a mobile communication terminal A 20, an address book management server 30, and a mobile communication terminal B 40.

In the present invention, when the user tries to synchronize his / her address book by accessing the address book management server 30 with the computer 10, in particular, to replace the old mobile communication terminal A 20 with the new mobile communication terminal B 40, the old mobile communication is performed. In order to store the address book with the new mobile communication terminal B 40 by matching the address book stored in the communication terminal A 20 with the address book previously stored in the address book management server 30, the mobile communication terminal A 20. ), And the address book entry is duplicated for the address book stored in the mobile terminal A (20) and the address book stored in the address book management server (30). It is organized and synchronized.

To this end, between the address book management server 30 and the mobile communication terminal (20, 40) by including a short phone number in the wCard to send and receive each other, the address book management server 30 from the mobile communication terminal A (20) The name and phone number of the received address book and the previously stored user's address book are compared with each other and the duplicate address book entries are sorted according to the modification date and time.

That is, the mobile communication terminal A 20 is an address book (hereinafter referred to as "address book") stored in a phonebook (Phonebook, phone book of the terminal) using an application which is already mounted, preferably an address book synchronization application running on a Wi-Fi platform. A ") is inserted into the wCard and transmitted to the address book management server 30. In particular, a wCard defined in the present invention is additionally provided with a field into which a speed dial number can be inserted, and the mobile communication terminal A 20 inserts a preset speed dial number into a wCard and transmits it to the address book management server 30. do.

In addition, the address book management server 30 is an address book (hereinafter referred to as "address book S1") previously stored in the mobile phone terminal user and the address book received from the mobile communication terminal A (hereinafter referred to as "address book A"). Compare and compare duplicate address book entries, generate a synchronized address book (hereinafter referred to as "address book S2"), and update and store address book S1 as address book S2. Here, it will be readily understood by those skilled in the art that the address book management server 30 performs a duplicate address book cleaning process after extracting and reading the address book from the wCard received from the mobile communication terminal A 20.

The mobile communication terminal B 40 extracts and reads the address book S2 from the wCard received from the address book management server 30 using an address book synchronization application and stores it in the phone book.

Meanwhile, the wCard defined in the present invention will be described in detail.

A wCard consists of a string, where one field consists of pairs of <Type> and <Value> on a single line, separated by a line break between fields. <Type> means the data type, and information such as N (name), TEL (telephone number), and REV (modification date and time) are included in the wCard.

The <Type> is composed of a <Type Name> and a <Type Parameter> (separated by ";"). In addition, there may be no <Type Parameter> for the <Type Name>, and a plurality may exist. Precede the <Type Parameter> with "Type =". On the other hand, <Value> is data corresponding to <Type>.

In particular, the present invention extends the wCard format so that information on the speed dial number can be used for address book synchronization. In other words, add a field defined with "S-Key" to the wCard.

The above-mentioned wCard format is summarized through [Table 1] as follows.

Field name Type Name Type Parameter name N none Phone number (mobile communication terminal) Tel Cell Date of modification REV none Speed dial S-Key none

Referring to Table 1, let's look at an example of a wCard with a speed dial number in Table 2 below.

example Explanation ＊＊＊
N: Hong Gil-dong
TEL; Type = Cell: 01012345678
＊＊＊
REV: 20031009T180135Z
S-Key: 5
＊＊＊ ＊＊＊

＊＊＊

By adding "S-Key" to <Type Name> as shown in [Table 2], the information on the speed dial number is included in the wCard. Thus, the speed dial number previously set in the mobile communication terminal A (20) is synchronized to the address book management server 30 through the wCard, the existing speed dial without the user's settings through the wCard received from the address book management server 30 The number is set in the mobile communication terminal B 40 without being changed. Hereinafter, a detailed description of the speed dial number will be omitted, and the duplicate address book cleaning process will be described in detail with reference to FIG. 2.

2 is a flow chart illustrating a preferred embodiment of a duplicate address book cleanup process according to the present invention.

As mentioned above, the address book management server 30 compares the name and phone number of each address book entry with respect to the address book S1 of the mobile communication terminal user previously stored and the address book A received from the mobile communication terminal A 20. After the duplicate address book entries are sorted according to the modification date, address book S2 is generated, and the address book S1 is updated and stored in the address book S2. In other words, the address book management server 30 searches for address book entries with duplicate names and phone numbers, and checks the modification date and time while sorting the contacts according to the index, leaving the most recently registered address book entries, and the duplicate address book. Delete the item. On the other hand, it is preferable that the address book management server 30 merge and arrange the corresponding field values registered in the duplicate address book items in the field in which no value is registered in the most recent address book item. Looking at the duplicate address book cleaning process performed in the address book management server 30 in more detail as follows.

First, an index is assigned to each address book item of the address book A and each address book item of the address book S1, and arranged in one address book, preferably the address book S1 (S100).

Subsequently, the name, phone number, and date and time of modification of each sorted address book item are checked (S101). As a result of this check, for example, address book items with duplicate names and phone numbers, address book entries with only names and phone numbers. Only the duplicate address book entries are referred to the modification date of each address book entry to proceed with the process of cleaning the duplicate address book entries.

First, referring to the modification date and time of the corresponding address book entries for the address book entries with duplicate names and phone numbers of the address book entries, the latest address book entries are left behind and the old address book entries are deleted (S102 and S103).

Second, by referring to the modification date and time of the corresponding address book entries for the address book entries with only duplicate address book entries, the phone number of the old address book entry is merged with the phone number field of the recent address book entry to leave the latest address book entry and the old address book. The item is deleted (S104, S105).

Third, for address book entries with only duplicate phone numbers of address book entries, whether each name exists in each address book entry (if the name field value is registered as a null value) is checked, and the modification date of the corresponding address book entries is checked. If the name does not exist in the recent address book entry and the name exists in the old address book entry as a result of determining whether the name exists by referring to the city, the name of the old address book entry is merged into the name field of the recent address book entry to The old address book entry is deleted and the old address book entry is deleted (S106, S107, S108). If present, the latest address book entry is left and the old address book entry is deleted (S109). S110), if a different name exists in both the old address book item and the recent address book item as a result of determining whether the name exists by referring to the modified date and time of the corresponding address book items, both the latest address book item and the old address book item are kept as they are. (S111).

In more detail, the same phone number is registered in each of the recent address book item and the old address book item according to the "S111 process", but it can be seen that different names are registered. This is to prevent the user from assigning a different name to the same telephone number intentionally and deleting it in the address book. In addition, the address book management server 30 notifies the user through a web page or an instant messenger or a mobile terminal about an address book item having the same phone number but registered under a different name in the process of cleaning the duplicate address book as described above. Duplicate address books may be organized according to the user's request by receiving information such as selective deletion of address book items and changed names.

Fourth, corresponding address book entries are maintained as they are for the address book entries in which none of the name and phone number of the address book entries overlap.

Finally, the address book entries arranged in "S103, S105, S108, S110, S111, S112 process" as described above are inserted into the address book S2, and the previously stored address book S1 of the mobile communication terminal user is updated to this address book S2. Save it. In addition, the previously stored address book S1 is preferably stored separately as a backup address book and provided when the user requests the restoration of the address book.

On the other hand, in organizing a duplicate address book, if a phone number different from the phone number registered in the recent address book item is registered in the old address book item, the address book is merged by merging the phone number of the old address book item into the recent address book item. It is preferable to proceed with the process.

In addition, when organizing a duplicate address book, if additional information (e.g., home address, company address, email address, etc.) is registered in addition to the above-described name and phone number, the corresponding information is entered in an empty field in the recent address book entry. It is desirable to proceed with the process of organizing the address book by merging and registering.

Meanwhile, as described above, the address book management server 30 may integrate the address book of the mobile communication terminal A 20 and the address book stored in its own DB to organize the duplicate address book, or to duplicate the user connected to the server. Depending on the address book cleanup request, duplicate address books can be cleaned up for the address book stored in its own DB. Here, the address book of the user stored in the address book management server 30 is the address book synchronized between the address book management server and the address book application mounted on the mobile communication terminal, the address book synchronized between the address book management server and the mail sending program mounted on a specific terminal, The address book synchronized between the address book management server and the instant messenger executed on the specific terminal is integrated into the mobile terminal user information.

3 is a diagram illustrating a preferred embodiment of a wCard to which the present invention is applied.

As described in FIG. 2, the address book management server 30 organizes the duplicate address book and inserts each address book item of the address book S2 into the wCard and transmits it to the mobile communication terminal B40.

3 shows a wCard (ie address book A) received by the address book management server 30 from the mobile communication terminal A 10, and a wCard shown on the left of FIG. 3 indicates the address book management server 30. Shows a wCard (that is, address book S2) transmitted to the mobile communication terminal B 40 as a result of arranging a duplicate address book by comparing the wCard shown on the left side of FIG. 3 with the previously stored address book S1.

Meanwhile, the duplicate address book arranging process in FIG. 2 will be described with the wCard illustrated in FIG. 3 as an example.

Index 1 and Index 2 are cases where both the name field value (A) and the telephone number field value (TEL # 1) are duplicates. In this case, the old address book entry index 1 is deleted and the latest address book entry index 2 is left. Put it.

Index 3 and Index 4 are cases where only the name field value (B) is duplicated. In this case, the telephone number (TEL # 2) of the old address book entry, Index 3, is merged into the telephone number field of the latest address book entry, Index 4. Delete index 3. In addition, index 4 is a case where only index 5 and the name field value (B) overlap, and in this case, the telephone number field of index 4, which is an old address book entry (TEL # 2), is the telephone number field of index 4, which is a recent address book entry. Merge and delete index 4. Thus, in the index 5, "TEL # 2, TEL # 3" is registered in the telephone number field.

In the case of index 6 and index 7, only the telephone number field value (TEL # 4) is duplicated. In this case, a telephone number different from the telephone number registered in the latest address book entry index 7 is registered in index 6, which is an old address book entry. Therefore, merge the telephone number of index 6 (TEL # 5, which does not exist in index 7) into the free telephone number field of index 7, merge the name of index 6 into the name field of index 7, delete index 6 and replace index 7 Leave Accordingly, in the index 7, C is registered in the name field and TEL # 4 and TEL # 5 are registered in the telephone number field.

In the case of index 8 and index 9, only the telephone number field value (TEL # 6) is duplicated and the name of the old address book entry does not exist and the name of the old address book entry exists. Delete the old address book entry, Index 8.

Index 10 and index 11 are cases where both the name of the latest address book entry and the name of the old address book entry exist while only the telephone number field value is duplicated. In this case, both the latest address book entry and the old address book entry are left.

4 is a flowchart illustrating a method for synchronizing a user address book between a mobile communication terminal and an address book management server according to the present invention. Hereinafter, an address book of a user of the mobile communication terminal A 20 in the address book management server 30, for example, an address book stored in the mobile communication terminal A 20 that the user uploaded to the mobile communication terminal A 20, The address book registered using the instant messenger and the address book stored in the mail sending program uploaded to the computer 10 by the user are integrated into one address book (address book S1) and described. In addition, the preferred embodiment of the present invention synchronizes the address book A stored in the old mobile communication terminal A 20 with the address book S1 stored in the address book management server 30 and stores it in the new mobile communication terminal B 40. It is also within the scope of the present invention to store the address book of the user stored in the computer 10 to the mobile communication terminal B 40 or the mobile communication terminal A 20 via the address book management server 30. If you can easily understand.

First, when the address book management server 30 receives an address book A request (preferably a duplicate address book cleanup request between the address book A and the address book S1 by the user) from the computer 10 (S200), the corresponding mobile communication terminal A (20). In step S201, the callback URL short message is transmitted to allow the user to access the address book management server 30. Accordingly, the mobile communication terminal A 20 accesses the URL included in the short message and transmits the address book A (S202).

Then, the address book management server 30 compares each address book item of the address book S1 previously stored in its own database with each address book item of the address book A received from the mobile communication terminal A 20, and sets up an address book synchronization setup, that is, duplicates. The address book cleanup process is performed (S203).

Thereafter, the address book management server 30 inserts and generates each address book item according to the result of the address book cleanup into the address book S2, and updates and stores the address book S1 to this address book S2 (S204).

Thereafter, the address book management server 30 displays the updated address book S1 through the web page to notify the user of the result of the duplicate address book cleanup, and sends the address book from the computer 10 to the mobile communication terminal B 40 by the user. When requested to download to the address book (S205), the address book S2 (preferably the address book S1 updated to the address book S2) while preparing to send the callback URL short-circuit so that the mobile communication terminal B 40 can access the address book management server 30 The message is transmitted (S206, S207).

Thus, the mobile communication terminal B 40 receives the address book S2 from the address book management server 30 by accessing the URL included in the short message (S208, S209). Thereafter, the mobile communication terminal 40 stores the address book S2 in the phone book to newly store or update the address book (S210).

Meanwhile, in the above-described embodiment of the present invention, the address book management server 30 has been described as an example of arranging the duplicate address book. However, in another embodiment of the present invention, the mobile phone downloads the address book from the address book management server 30. In the terminal, preferably, the mobile communication terminal B 40 may duplicate the address book. Here, it is preferable that the duplicate address book cleaning process is performed by the address book synchronization application mounted in the mobile communication terminal B 40.

Looking at this, the address book management server 30 transmits the wCard to the mobile communication terminal B 40 as it is without performing a separate operation on the wCard received from the mobile communication terminal A (20).

Accordingly, the mobile communication terminal B 40 sorts each item of the address book included in the wCard received from the address book management server 30 and checks the name, phone number, and date and time of modification of each address book item. And after arranging each of the address book entries having duplicate telephone numbers with reference to each modification date and time, the arranged address book entries are stored in the terminal phonebook.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.
