Abstract

A call processing method associated with a text-based user telephone number guide service and a service center therefor are provided to preset whether a user wants to show a self telephone number, whether to deliver a representative telephone number of the center to a caller's terminal, and a processing method for a call by the caller, thereby preventing infringement of privacy. A user as a called party presets a self telephone number showing target(S100), and presets a call processing option for a call received from a caller(S200). If a telephone number inquiry request is received by designating a character string corresponding to the user(S400), a service center identifies the called party corresponding to the character string(S500), and decides whether the caller is included in the user's telephone number showing target(S600). If not, the service center determines whether to deliver a self-controlled telephone number(S700). The center delivers the number to the caller's terminal while storing inquiry records of the caller(S900). If a call is received from the caller's terminal, the center receives the call(S1000), and identifies the called party to which the call is to be forwarded(S1100), then processes the call according to the call processing option(S1200).

The present invention relates to a call processing method associated with a text-based user phone number guide service and a service center therefor.

A representative example of a conventional telephone number guide service is a "114" service. Pressing the call button after entering the number "114" through the wired or wireless telephone is connected to the information center, and through the interchange of voice information with the guide of the information center, the desired callee's telephone number is guided. On the other hand, a typical example of the conventional telephone call service is to call the other party by pressing the call button after inputting the callee's telephone number using a wired or wireless telephone. However, the telephone call by the method of inputting the telephone number of the called person is severely limited by the limitation of the memory of the user.

Instead of inputting a telephone number, a telephone number guide service using text values that a user can easily remember has attracted attention. Examples of telephone number guidance services using character values include Korean Patent No. 469,810, Korean Patent Publication No. 2005-94707, Korean Patent Publication No. 2004-47705, Korean Patent Publication No. 2004-47500, Korean Patent Publication The publications 2005-86307, WO 2000/73998 and Korea Patent Publication No. 2001-112795 are mentioned. The contents described in the above patent documents and the documents cited therein are hereby incorporated by reference in their entirety.

1 is a block diagram showing a representative example of a character-based telephone number guide service system according to the prior art. As shown in FIG. 1, the text-based telephone number guide service system 1 is a service center for maintaining user identification information 11 consisting of character strings and user telephone numbers 12 linked to the character strings (hereinafter, A "character based telephone number guide service center" or simply "service center") 10; A service application 21 having a function of accessing the character-based telephone number guide service center 10, an alphanumeric / call control button 22, a display 23, and a data processing module provided inside the terminal. A terminal 20 including 24; The text-based telephone number guide service center 10 and the mobile communication network 30 through which the terminal 20 is formed. First, when the user activates the service application 21 provided in the form of a menu of the terminal 20, a text input window is generated on the display 23 of the terminal by the service application 21 and provided to the user. By inputting a character string into a character input window by a user and clicking a transmission button among subsequent call control buttons, the character string is transmitted through the mobile communication network 30 together with terminal identification information. Is passed to (10). The text-based telephone number guide service center 10 extracts the telephone number of the called party corresponding to the string based on the received string, and transfers the extracted telephone number to the caller terminal 20. The caller terminal 20 performs a telephone call to the called party using the transferred telephone number. The character-based telephone number guide and telephone call service has an advantage of improving accessibility to the called party by using a string that the user can easily remember, such as a user name and a company name. Despite these advantages, the text-based telephone number guide service has the following problems.

First, personal privacy may be violated. For example, suppose a singer "Madonna" is subscribed to the character-based phone number guide service. In this case, many fans will ask for the phone number of the singer "Madonna" and the singer "Madonna" will suffer from numerous calls.

Second, the called party's telephone number is stored in the caller's terminal. Most of commercially available terminals are configured to store recent call history. Thus, the telephone number of the called party can be retrieved at any time by the caller, and can also make a call to the called party from time to time. This results in unprotected exposure of a particular person to the stalker. Furthermore, it may be used for crime.

The two problems are the barriers to lowering the utilization rate of the text-based telephone number guide service center and preventing subscribers, especially individuals. In order to activate the text-based telephone number guide service center, it is important to secure enough individual subscribers, and based on this, stable operation of the text-based phone number guide service center is ensured. Therefore, a method for solving such a problem is required.

Call processing method associated with the user's telephone number guide service according to the present invention is:

a) receiving terminal identification information and a callee's string from a caller terminal;

b) identifying the called party based on the string;

c) checking whether the caller is included in a user's telephone number disclosure target preset by the called party based on the terminal identification information;

d) delivering the called phone number to the caller terminal when the caller is included in the user's telephone number disclosure target as a result of the checking in step c);

e) if the caller is not included in the user's telephone number disclosure target as a result of checking in step c), the caller terminal displays a message indicating that the guidance of the representative telephone number or the called telephone number of the service center is limited. Transmitting to the caller terminal when the representative phone number of the service center is transmitted to the caller terminal, storing the caller's telephone number inquiry history; And

f) when the call is received from the caller terminal while the representative phone number of the service center is delivered to the caller terminal, identify the called party to forward the call based on the caller's telephone number inquiry history, And processing the call according to a call processing option preset by the caller.

2 is a flowchart showing a preferred embodiment of a call processing method associated with a user phone number guide service according to the present invention. As shown in FIG. 2, the user as the called party may set his or her own phone number disclosure target in advance (S100). In addition, it is possible to set in advance the call processing option for the call from the caller to be made if the telephone number is not subject to disclosure (S200). The data input by the user is transferred to the service center and made into a database (S300). At this time, when a call number inquiry request is received by designating a string corresponding to the user (caller) by the caller (S400), the service center identifies the caller corresponding to the string (S500). After performing the callee's identification procedure, the service center refers to the list of target subjects preset by the called party based on the terminal identification information, and whether the caller is included in the user's telephone number disclosure target. Determine (S600). As a result of the determination, when the caller has a right to view the called party's telephone number, the service center transmits the called telephone number to the caller's terminal (S1300). The caller may make a direct telephone call with the called party using the received callee's telephone number. On the other hand, if the caller does not have a right to view the called party's telephone number, the service center determines whether or not the transfer of the telephone number under its management, not the user's telephone number (S700). The authority to decide whether the telephone number under the management of the service center ("main telephone number of the service center" or simply "representative telephone number") is delivered is determined in accordance with the operation policy of the service center. Thus, when the caller is a user who does not have the right to view the called party's telephone number, by default, the representative telephone number of the service center can be provided by the service center. If necessary, the user may decide whether or not to forward the representative phone number of the service center. As a result of the determination in S700, if the representative phone number of the service center is not also delivered, a message (simply, a service restriction message) indicating that the guidance of the called party's phone number is limited is transmitted to the caller terminal (S800). . If necessary, the message may be added with guidance of various additional functions (eg, a voice message). As a result of the determination of S700, when the representative telephone number of the service center is to be transmitted to the caller terminal, the service center transmits the telephone number under its management to the caller terminal, and provides the caller's telephone number inquiry history. Save (S900). When the call is received from the caller terminal while the representative phone number of the text-based telephone number guide service center is delivered to the caller terminal, the call is received by the service center (S1000). The service center identifies the called party to forward the call based on the caller's telephone number inquiry history (S1100) and according to the call processing option preset by the called party (for example, presence or absence of forwarding to the called party). In step S1200, the call is processed.

According to the present invention, a subscriber of a service center having a text-based user phone number guide service and a call processing service function can preset his / her phone number disclosure target. In other words, the user as the called party can set in advance the subject to which his / her telephone number is disclosed.

Suppose that user "A" (caller) wants to make a call to user "B" (caller), but the caller does not know the caller's phone number. In this case, the caller will request the caller's telephone number from the service center by specifying a string corresponding to the callee. The request information delivered to the service center includes the string and terminal identification information. The service center refers to a database managing a string and a user in association with each other to identify a called party matching the string. The service center then checks whether or not the caller is included in the user's telephone number disclosure target based on the terminal identification information with reference to the disclosure target list preset by the called party.

If the specific caller is included in the user's telephone number disclosure target, that is, if the specific caller has a right to view the user's telephone number, the service center searches for the called telephone number and delivers it to the caller terminal. do. In this situation, the caller uses the received called phone number to make a call to the called party.

According to the present invention, the subscriber of the service center can pre-set his / her telephone number disclosure target, and can also pre-set the response procedure for the call from the caller, which is not included in the telephone number disclosure target. In other words, although not included in the telephone number disclosure target, it is possible to pre-set the response procedure for the call from the caller (these calls are forwarded to the call processing agent under the management of the service center). Specifically, if the specific caller does not have a right to view the user's telephone number, a message indicating that the guidance of the representative telephone number or the called telephone number of the service center is limited according to the options preset by the called party. Is delivered to the caller terminal. Here, when the representative phone number of the service center is transmitted to the caller terminal, the service center stores the caller's telephone number inquiry history (caller terminal identification information, caller identification information, etc.).

Specifically, suppose that the representative telephone number of the service center is provided to the caller terminal instead of the called telephone number. While a service application is active, if a telephone call request is made by the caller to the called party, this call is forwarded to the service center. At this time, the service center processes the call according to the call processing option preset by the called party. This matter will be described later.

According to a preferred embodiment of the present invention, based on the user telephone number disclosure management option and the user call processing management option, the user's telephone number guide and the call to the called party are controlled reasonably. 4 shows an embodiment of a web page provided to a user for determining whether to disclose a user's telephone number. As shown in FIG. 4, the web page 400 displayed on the user screen includes an area 410 for confirming the person to whom the telephone number has been disclosed. Referring to Figure 4 in more detail as follows. If the user selects the disclosure of telephone number to all callers option 411, the user's telephone number is provided to all callers. On the contrary, when the user registration option 412 having the telephone number viewing authority is selected, the input window 430 for inputting specific terminal identification information is activated. A user may designate a person having access to his / her telephone number by inputting specific terminal identification information to the input window 430. At this time, an area 420 for confirming the processing method when receiving a telephone number inquiry request from an unregistered caller may be activated and provided. For telephone number inquiry from an unregistered user (caller), a representative telephone number providing option 421 of a service center or a representative telephone number of a service center may also not be provided option 422. If necessary, the service center may set the representative telephone number providing option 421 of the service center as a default for the telephone number inquiry from the unregistered user (caller) as described above. In FIG. 4, a representative telephone number providing option of a service center is provided for selecting a user registration option 412 having authority to view a telephone number, thereby registering a user with an input window 430, and querying a telephone number from an unregistered user. The selected case of 421 is illustrated.

5 is a case where a representative telephone number of a service center is provided to an unregistered user by selection of the representative telephone number providing option (421 of FIG. 4) of the service center by the user or by default according to the policy of the service center. It shows an example of a web page provided to the user to determine how to handle the call when the caller's call is received at the service center. When the representative telephone number of the service center is provided to the unregistered user, the call processing option when the caller's call is received by the service center is the call forwarding management option area 510 and the additional function selection option when not performing forwarding. Region 520. As the call forwarding management option 510, a forwarding option 511 for all calls, a forwarding option 512 only for registered callers, and a forwarding option 513 after confirming whether or not forwarding is performed may be provided. . When the forwarding option 512 is selected only for the registered caller, an input window 530 for user registration is generated and provided. In addition, as an additional function selection option 520, a call history storing option 521 and a call history not storing option 522 may be provided. As an additional function, for example, voice message recording and the like may be added, which will be apparent to those skilled in the art. In FIG. 5, the case where the call history storage option 521 is selected for the selection of the forwarding option 512 only for the registered caller, the user registration by the input window 530, and the call from the unregistered user are selected. To illustrate.

Accordingly, through the above procedure, the user telephone number disclosure management option may be selected from the following selection options:

i) disclose your telephone number to all callers;

ii) disclosure of the user's telephone number to callers registered by the user and disclosure of the text-based telephone number guidance and representative telephone numbers of the call-call service center to the unregistered callers; And

iii) disclosure of the representative's representative telephone number to all callers;

iv) Your telephone number and the representative's main telephone number are closed to all callers.

For telephone number inquiry from an unregistered user, the user call processing management option, when provided with the representative telephone number of the service center, may be selected from the following selection options:

i) performing forwarding for all calls;

ii) performing forwarding after confirming whether or not forwarding is performed for all calls;

iii) forwarding is performed for calls from registered callers, and unregistered callers confirm forwarding before performing forwarding;

iv) forwarding for calls from registered callers, ignoring calls for calls from unregistered callers, and storing call history;

v) forwarding for calls from registered callers, ignoring calls for calls from unregistered callers and not storing call history;

vi) save call history without forwarding all calls; And

vii) Ignore all calls and do not save call history.

Fig. 6 shows a concrete implementation of the user telephone number disclosure management and user call processing management table of user " YYY ". In Fig. 6, the user "YYY" is a user telephone number disclosure management option 601, which is a user registration option having authority to view telephone numbers, specifically "923-kkk-kkkk" (terminal identification information of "KKK") and " 923-zzz-zzzz "(terminal identification information of" ZZZ ") was granted only the telephone number viewing authority, and the representative telephone number providing option of the service center was selected for telephone number inquiry from an unregistered user.

Further, when a call by the caller is received at the service center while the representative telephone number of the service center is provided, the call processing option 602 is set to "923-xxx-xxxx" (terminal identification information of "XXX"). Only forwarding was performed, and the option to save only the call log for calls from other users was selected. In this situation, when the caller " KKK " designates a character string corresponding to " YYY " and performs the telephone number inquiry request to the service center, the service center confirms the terminal identification information from the request information. After confirming the terminal identification information, the user telephone number disclosure management option 601 is inquired. At this time, the specific caller " KKK " is a user who has the right to view the telephone number of " YYY ". Therefore, the service center provides telephone number information (eg, 923-yyy-yyyy) of the user "YYY" to the terminal of "KKK". On the other hand, when a telephone number inquiry request is received from "XXX" by specifying a character string corresponding to "YYY", the service center is a user who has the right to view the telephone number of "YYY". Provide a representative telephone number for the service center. In addition to the representative telephone number of the service center, the service center stores that "XXX" has inquired a telephone number of "YYY". If "XXX" has made a call by pressing the call button while the representative phone number of the service center has been delivered, the call will be transferred to the service center. At this time, the service center confirms that "XXX" has inquired the telephone number of "YYY" from the telephone number inquiry history information, and inquires the call processing option 602 of "YYY". At this time, "XXX" is a forwarding target. Thus, the service center forwards the call of "XXX" to "YYY". Through this process, "YYY" can make a call with "XXX" without exposing his / her phone number to "XXX".

Hereinafter, the user telephone number disclosure management option and the user call processing management option will be described in more detail.

A. Detailed description of the management options for user phone number disclosure

In the user telephone number disclosure management option, when a particular subscriber selects the first option (“publish user telephone number to all callers” option), all callers have access to the subscriber's telephone number. The service center transmits the telephone number of the subscriber to the caller terminal in response to all requests specifying the character string corresponding to the subscriber. In this situation, the caller may make a call to the called party using the received user telephone number. Thus, the service center may not be involved in the telephone connection between the caller and the called party.

The caller (or caller's terminal) registered by the subscriber, if the particular subscriber selects the second option (the "Publish user's phone number to callers registered by the user and the representative's main phone number of the service center to unregistered callers" option). Only have access to the subscriber's telephone number. When the service center receives the telephone number request specifying the character string corresponding to the subscriber, the service center checks whether the caller is a user registered by the called party based on the caller terminal identification information included in the request information. If the caller is a registered user, the called phone number is delivered. If the caller is not registered, the representative's telephone number of the service center is delivered. At this time, the service center stores the caller's telephone number inquiry history (caller terminal identification information, called party identification information, etc.) in an appropriate storage medium (eg, a storage or data server). Therefore, a user as a callee can register a subject to disclose his / her telephone number in advance, and make his / her own telephone number visible only to the registered user.

If a particular subscriber selects the third option ("disclose the representative's telephone number of the service center to all callers" option), the service center will provide the representative's telephone number of the service center for every request to retrieve the subscriber's telephone number. Stores caller's telephone number inquiry history. In this case, the user as the callee can appropriately control the caller by referring to the call processing management option described later without revealing his / her telephone number.

If a particular subscriber selects the fourth option ("Private caller's telephone number and representative's main phone number for all callers" option), the service center will respond to all requests for inquiring about the subscriber's telephone number, "callee's phone number." Message is sent to the caller's terminal. Meanwhile, the service center may add a message indicating that a voice message can be left along with the message and transmit the message to the caller's terminal, and store the voice message in a storage medium according to a known procedure. In addition, the service center may appropriately store the caller's callee's telephone number inquiry history (caller terminal information, time of inquiry, etc.) in a storage medium, or may transmit the caller's telephone number inquiry history in the form of a text message to the called terminal.

B. Detailed description of user call handling management options

According to the present invention, even when the representative telephone number of the service center is transmitted to the caller's terminal, the caller can make a call to the called party based on the call processing option preset by the called party. This is done by the user call processing management option. If the subscriber as the called party selects the third option of the user's telephone number disclosure option or receives a telephone number lookup request from an unregistered user of the second option, the service center calls the representative's telephone number of the service center. Deliver to the terminal. At this time, the service center indicates to the caller terminal that the transferred telephone number is the representative telephone number of the service center according to the request of the subscriber or the operation policy of the service center or the call processing option selected by the subscriber, or the called party. You can do it as if it's a phone number. In such a situation, a call request from the caller to the callee may be made. Specifically, when a call to the received telephone number is performed while the service application embedded in the terminal is activated, the call is transferred to the service center. At this time, the service center processes the caller's call by referring to the caller's telephone number inquiry history information and the user call processing management option described above. In this case, even if the user as the called party makes a call with the caller by the approval of the forwarding, the representative phone number of the service center is exposed to the caller instead of his own phone number. Therefore, the telephone number of the called party is not exposed to the outside. Thus, the subscriber as the called party receives the caller's call without exposing his / her telephone number to the outside.

If a particular subscriber selects the first option of the user call processing management option ("Perform Forwarding for All Calls" option), the service center forwards all calls from the caller to the called party. At this time, the telephone number inquiry history information of the above-mentioned caller is used to confirm who is the recipient of the call from the caller. The service center identifies the recipient of the call from the caller based on the caller's telephone number inquiry history information stored in the storage medium and processes the call. There is no callee's phone number left in the caller terminal. Thus, the called party can establish a telephone connection with the caller without exposing his / her telephone number to the outside.

If a particular subscriber selects the second option of the user call processing management option ("forwarding whether all forwarding is performed in advance and then forwarding"), the service center is based on the caller's telephone number inquiry history information described above. Then, the called party is identified, the callee's response is confirmed, and the call processing based on the called party is performed. For example, when the caller's call is made while the caller's terminal number is delivered to the caller's terminal, the call is received from "923-xxx-xxxx. If you want to forward, call" 1 ". The message "Press 2" to disregard may be sent from the service center to the called terminal. To enhance the satisfaction of the called party, a menu such as allowing voice message recording and / or storing call history information may be added. Specifically, a call was received from "923-xxx-xxxx." 1 "for forwarding," 2 "for allowing the caller to record a message, and" 3 "for storing the call log information. To ignore, press "4", the message may be delivered to the called terminal. The service center receives the called party's response information and then processes the call based on this.

When a particular subscriber selects the third option of the user call processing management option ("forwarding calls from registered callers and forwarding of unregistered callers after confirming whether or not forwarding is performed" option), the service. The center first identifies the called party based on the caller's telephone number inquiry history information. Thereafter, it is checked whether or not the caller is included in the forwarding target preset by the called party. If the caller is a user registered in advance by the callee, the service center forwards the call from the caller to the callee. Even in this situation, the called party's telephone number is not exposed to the calling party's terminal. In contrast, if the caller is not a user registered by the callee, the service center has received a call from, for example, "923-xxx-xxxx. If call forwarding is" 1 ", the call is ignored. Press "2" to send the message to the called terminal. After receiving the callee's response, the call is then processed from the caller to the callee. The same is true that the called party's telephone number is not exposed to the caller's terminal.

If a particular subscriber selects the fourth option of the user call processing management option ("forwarding calls from registered callers and ignoring calls from unregistered callers and storing call history" option); The service center first identifies the called party based on the caller's telephone number inquiry history information. Then, it is checked whether or not the caller is included in the forwarding target set in advance by the called party. If the caller is a user registered in advance by the callee, the service center forwards the call from the caller to the callee. If the caller is not a user registered by the callee, the service center stores the call history of the caller. This call history information allows the called party to check the details of the calls made to them. Therefore, the call history information is databased based on the called party. The call history information may include, for example, caller terminal identification information, call time, and the like. On the contrary, the above-mentioned telephone number inquiry history information is primarily for identifying the called party by the service center. Therefore, the telephone number inquiry history information is databased on the basis of the caller. The telephone number inquiry history information includes caller terminal identification information and called party identification information, and a telephone number inquiry time may be added. At this time, the telephone number inquiry history information may manage only the most recent telephone number inquiry history. If necessary, the service center may grant the callee access to the telephone number inquiry history information, but this is optional.

When a particular subscriber selects the fifth option of the user call processing management option ("forwarding calls from registered callers and ignoring calls from unregistered callers and not storing call history" option). The service center processes the call to the called party by the caller in the same manner as the fourth option described above, except that the call center does not store call history information.

If a particular subscriber selects the sixth option of the user call processing management option ("Do not forward call for all calls, save call log" option), the service center does not perform forwarding for all calls. Only save history information. As the called user, the user can view the call history information and inquire the call history made for himself. After that, you can selectively make calls only to the callers you need.

If a particular subscriber selects the seventh option of the user call processing management option (“Ignore all calls, do not store call history” option), the service center ignores all calls made to the subscriber. Therefore, the service center sends a message to the caller, "Callee cannot currently answer the call. To leave a message, press the # button."

3 is a block diagram showing a preferred embodiment of a service center performing call processing in connection with a text-based telephone number guide according to the present invention. As shown in FIG. 3, the service center 100 includes a data input / output unit 110, a data processing and control unit 120, a database 130 for managing various information of a user, a search unit 140, and data. A storage unit 150 and a call processing unit 160. The data input / output unit 110 exchanges data with the caller terminal 200 through a mobile communication network (not shown). Specifically, the telephone number inquiry request of a specific user (caller) is received from the caller terminal 200, and the data corresponding to the request is transmitted to the terminal 200. In addition, when the call button is activated by the caller while the representative phone number of the service center is transferred to the caller terminal, the caller 200 receives a call from the caller terminal 200. At this time, the reception / response of the telephone number inquiry request and the reception of a call made from the caller terminal to the service center may be separately processed. That is, two physically independent data input / output units can independently handle the reception of a call made from the caller terminal to the service center. Reference numeral 111 in FIG. 3 denotes a telephone number inquiry request reception / response unit, and reference numeral 112 denotes a reception unit of a call made from a caller terminal to a service center. In the service center performing call processing in connection with the text-based telephone number guide according to the present invention, the following data is maintained in a database:

(1) user information (eg user name);

(2) character string information associated with the user identification information (eg, the character "YYY" specifying the user);

(3) the user's telephone number information (eg 923-yyy-yyyy);

(4) user phone number disclosure management option information for determining whether or not to disclose the user's phone number (as detailed above);

(5) user call processing management option information for determining call processing methods from the caller (as detailed above); And

(6) Caller's telephone number inquiry history information.

They may all be managed in one database (130 in FIG. 3), individually linked and managed by a plurality of databases, or some combination may be managed by one database. The present invention exemplifies that the first to fifth data are managed by the first database 131 and the sixth information is managed by the second database 132 for convenience of understanding. In addition to the above-described data, various additional data (eg, user billing matters) may be stored in the data storage unit 150, and may be databaseized and managed.

The search unit 140 extracts the called phone number. Specifically, when the telephone number inquiry request is received from the caller terminal 200 having the right to view the telephone number of the called person, referring to the first database 110, the called telephone number is extracted and the data input / output unit ( To 110). On the other hand, if a call by the caller is performed while the representative phone number of the service center is delivered to the caller terminal, the search unit 140 checks the phone number inquiry history to confirm the callee terminal 300 to be forwarded. Based on the information, the called telephone number is extracted. Then, if the caller's call needs to be forwarded to the called party's number, it is forwarded to the call processing unit 160 for processing. A call is established between the caller terminal 200 and the caller terminal 300.

At this time, the user terminal 200 as a caller includes a service application 201 having a function of connecting to the service center 100, an alphanumeric / call control button 202, a display 203, and an inside of the terminal. It includes a data processing module 204 provided in. The service center 100 and the terminals 200 and 300 exchange data through a mobile communication network (not shown).

First, when a user activates a service application 201 provided in the form of a menu of the terminal 200, a text input window is generated by the service application 201 on the display 203 of the terminal and provided to the user. By inputting a character string into a character input window by a user and clicking a transmission button among subsequent call control buttons, the character string is transmitted to the service center 100 through a mobile communication network (not shown) together with terminal identification information. Delivered. The service center 100 identifies the called party linked to the string based on the received string, and based on the user call processing management option information for determining the user telephone number disclosure management option information and the call processing method from the caller. Process a call received from the service center 100 in connection with the telephone number inquiry request or the like.

On the other hand, the call processing method associated with the phone number guide service according to the present invention may operate in conjunction with the user phone page service. Specifically, when providing the telephone number or the representative telephone number of the called party in response to a request of the called party's telephone number by the caller, the user's phone page may be provided together. When a caller makes a call while the user's phone page is active, the call is delivered to the caller's terminal with the phone number provided with the phone page, specifically the caller's phone number or the representative phone number of the service center. The call is processed according to the call handling options. 7 shows a preferred implementation of the user interface displayed on the display of the caller terminal after the connection is made to the service center. As shown in FIG. 7, the information received from the service center 100 includes the called user's phone page 103 corresponding to the character string input by the user, the called party's telephone number 102 and / or linked thereto. Or a representative telephone number of a service center. In FIG. 7, user phone page 103 and user phone number 102 are presented together, but this is exemplary. When the provision of the user phone number 102 is limited, the representative phone number of the service center may be provided. If necessary, only the user phone page 103 may be presented, in which case the called phone number 102 or the representative phone number of the service center is embedded. The user phone page 103 may include a greeting 1031 of the called party, a picture or video 1032 of the called party, and / or an event guide 1033. These are all maintained by the called party. That is, the called party can implement in a form suitable for expressing itself. By providing the user (or called) phone page 103 together, it is possible to obtain not only easy identification of the called party from the phone page, but also various information about the called party. The content and format included in the user phone page 103 are not particularly limited. The information presented in FIG. 7 should be construed as illustrative. The called user can implement his / her phone page in various forms in consideration of the capacity and data processing speed supported by the service center. The user phone page 103 may include various menu functions (for example, call menu 1034, guestbook menu 1035, friend registration menu 1036, etc.), and the user accesses his / her phone page. In this case, a menu function necessary for new registration and update of the phone page may be additionally provided. See PCT / KR2005 / 004184 for more details on user phone page 103.

Therefore, invasion of privacy due to exposure of the user's telephone number is prevented. Celebrities, politicians, sportsmen, etc., may suffer from various spam calls when an individual's phone number is exposed. These users can set their phone number to be private and to provide the caller with the representative phone number of the service center. In this case, the call by the caller is delivered to the representative telephone number of the service center, and based on the call processing management option set by the user, forwarding is performed only for the call from the registered user, or after confirming whether or not forwarding is performed in advance. By storing only the call log without proceeding or forwarding, the privacy of the individual can be properly protected. At this time, if the option to confirm in advance whether to perform the forwarding is selected, a message confirming the specific method of the call response to the called party's terminal is transmitted along with the caller identification information (for example, the caller's name and / or caller terminal) . The user may decide whether to perform forwarding based on the received message. Thus, the user as the called party can answer the caller's call without exposing his / her telephone number at all. This allows for rational control of text-based phone number guidance and associated calls.
