Description

Change phone number server and method {SERVER AND METHOD FOR INFORMING CHANGED PHONE NUMBER}

The present invention relates to a modified telephone number guide server and method, and more particularly, to enable a convenient use for a user who wants to know the changed telephone number of the other party, and to the user of the changed telephone number to inform the changed telephone number to an unwanted counterpart. The invention relates to a server and a method for changing telephone number guidance.

In general, unique telephone numbers are set in wireless communication terminals and landline telephones. This phone number is also used as an ID that tells who you are when you call someone, but most of all, it is used by someone to choose the terminal you want to call.

Recently, terminal users frequently change their phone numbers due to replacement of terminals, prevention of stalkers, and change of residence. Therefore, it is necessary to inform everyone who knows the changed phone number, and it is not so easy to inform people of the changed phone number.

A conventional method for solving this problem is to register a phone number change notification service. What is the phone number change notification service? When you change your current phone number to a new phone number, you can register for the phone number change notification service. A service that informs you or automatically connects a call to a changed phone number.

However, such a conventional method provides a telephone number change notification service to everyone regardless of who is calling, so that an insignificant person or a malicious call, such as when the frequency of calls is extremely low or one-off, is called. There was also a problem of unnecessarily exposing a user's phone number to certain people who are calling.

On the other hand, according to frequent changes of the telephone number, the telephone number before the change may have a history of being used as a telephone number of multiple users at different times. In such a case, when the user wants to know the changed telephone number of the telephone number before the change, the telephone number change notification service guides the changed telephone number of the recent user. In this case, the recent user may not be the intended user.

Therefore, if there are a plurality of users who used the past phone number, a method for allowing the sender to know the changed current phone number of the desired user is required.

The present invention is to provide a modified telephone number guide server and method for enabling a convenient use for a user who wants to know the changed telephone number of the other party, and do not guide the changed telephone number to an unwanted counterpart of the user of the changed telephone number. .

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed. Other objects, which will be apparent to those skilled in the art, It will be possible.

The change telephone number guide server of the present invention for achieving the above object is a number storage unit for storing the number information including the current number and user information of the receiving terminal and at least one past number, the calling terminal after being connected to the calling terminal A number receiving unit for receiving a telephone number to be inputted from the terminal; extracting one or more number information including a past number identical to the received telephone number among the stored number information; A number information extracting unit for assigning an identifier, a message transmitter for transmitting the user information of each number information to which the identifier is assigned according to the order of the identifier and a message including the assigned identifier to the transmitting terminal, and after the message is transmitted. Receive an identifier selected by the transmitting terminal The apparatus may include a number guide for transmitting the current number of the number information to which the selected identifier is assigned among the number information to which the identifier is assigned.

In this case, the number information may further include a valid time point of each past number, and the number information extracting unit may give the identifier in the reverse order based on the valid time point of the same past number.

The number information may further include guide method information that is set to one of a manual guide or an automatic guide of the current number, and the number guide unit may include information on the number information to which the selected identifier is assigned when the guide method information is set to automatic guide. If the current number is transmitted to the transmitting terminal, and the guidance method information is set to manual guidance, the current number of the number information to which the selected identifier is assigned is not transmitted to the transmitting terminal without transmitting the current number of the number information to which the selected identifier is assigned. The call number of the transmitting terminal and the current telephone number guide wish message can be transmitted to the number.

In this case, the current telephone number guide wish message may include at least one of a text message generated by the number guide unit or a voice message transmitted from the transmitting terminal.

The number information may further include one or more rejected call numbers for rejecting the guidance of the current number, wherein the number information extracting unit includes a rejected call number equal to the call number of the transmitting terminal among the extracted number information. The identifier may not be assigned to the information.

On the other hand, the modified telephone number guide method of the present invention comprises the steps of storing the current number and user information of the receiving terminal and one or more past numbers and the number information including the valid time of each past number, after the call is connected to the transmitting terminal Receiving a telephone number input from the terminal, extracting one or more number information including a past number identical to the received telephone number among the stored number information, and a valid time point of the same past number for each extracted number information Giving a sequential identifier of a code that can be input by the transmitting terminal in a reverse order, and transmitting a message including user information of each number information to which the identifier is assigned according to the order of the identifier and the assigned identifier. Transmitting to the terminal and transmitting after transmitting the message And receiving the selected identifier from the terminal and transmitting the current number of the number information to which the selected identifier is assigned among the number information to which the identifier is assigned, to the transmitting terminal.

In this case, the number information further includes guide scheme information set to one of a manual guide or an automatic guide of the current number, and the step of transmitting the current number comprises: receiving a selected identifier at the transmitting terminal, the guide scheme information Transmitting the current number of the number information to which the selected identifier is assigned to the transmitting terminal when the information is set to automatic guidance, and transmitting the current number of the number information to which the selected identifier is assigned when the guidance method information is set to manual guidance. And transmitting the call number and the current telephone number guide wish message of the transmitting terminal to the current number of the number information to which the selected identifier is assigned without transmitting to the terminal.

Here, the current telephone number guide wish message may include at least one of a self-generated text message or a voice message transmitted from the transmitting terminal.

In addition, the number information further includes one or more rejected call numbers for rejecting the guidance of the current number, and the step of assigning the identifier includes a rejected call number equal to the call number of the transmitting terminal among the extracted number information. The identifier may not be given to the number information.

As described above, according to the change telephone number guide server and method according to the present invention, when a change telephone number guide is requested, first, the information of past users of the past number inputted is guided, and the current telephone number of the selected past user is guided. Thus, even if a plurality of past users of the same past number are provided, accurate guidance is possible.

In addition, when guiding information of past users, the user may increase convenience of a user who wants to know a changed telephone number by guiding in reverse order based on the valid time of the corresponding past number.

On the other hand, when the user (recipient) of the change telephone number (current number) to be guided wants to check before the current number guidance, the current number guide is sent by sending a text message or a voice message of the sender generated by the change telephone number guidance server to the receiver. Can be replaced. The receiver checks the text message or voice message and then connects to the sender if he / she desires, so that the caller can ultimately talk to the desired receiver. This allows the recipient to not announce the current number to an undesired sender.

In particular, it is possible to effectively protect the user of the changed telephone number to be guided by not including his or her information in the information guide of past users for the specific number.

2 is a flow chart showing a modified telephone number guide method of the present invention.
3 (FIG. 3A, FIG. 3B) is a flowchart showing a change phone number registration method associated with the change phone number guide method of the present invention.

Hereinafter, a modified telephone number guide server and method related to the present invention will be described in detail with reference to the accompanying drawings.

For convenience of description, a user who wants to receive a changed telephone number is referred to as a sender, and a user who uses the changed telephone number is referred to as a receiver. Further, it is assumed that a transmitting terminal is a terminal used by the sender, and a receiving terminal is a terminal used by the receiver.

1 is a block diagram showing a modified telephone number guide server of the present invention.

The change telephone number guide server shown in FIG. 1 is a number storage unit 110 which stores number information including a current number and user information of a receiving terminal and at least one past number, and is input from the transmitting terminal after a call connection with the transmitting terminal. A number receiving unit 130 for receiving a telephone number, extracting one or more number information including a past number identical to the received telephone number among the stored number information, A number information extracting unit 150 for assigning a sequential identifier, a message transmitter for transmitting a message including the user information of each number information to which the identifier is assigned and the assigned identifier to the transmitting terminal according to the order of the identifier ( 170) and receiving the selected identifier from the transmitting terminal after the message transmission Includes a number of guide members (190) for transmitting a current number of the number information, the code information that the selected identifier assigned to the transmission of the given self-terminal.

The number storage unit 110 stores the number information, which includes the current number and user information of the receiving terminal and one or more past numbers. The current number of the receiving terminal refers to the telephone number currently used by the receiving terminal, that is to say that the recipient is currently using. The user information includes information that can distinguish the recipient from other people, and may include, for example, a name, address, and a workplace. In general, the user information also includes the telephone number of the corresponding recipient, but the telephone number is not included in the user information in this specification because it is managed separately.

The past number is a number used before the current number being used by the receiver, and may be plural in some cases. At this time, the past number included in the number information may be some past numbers selected by the receiver. For example, if a certain recipient has 10 past numbers, the number information may include only 5 past numbers selected by the recipient.

As such, the number information including the current number, the user information and the past number may be generated and stored by the input of the receiver, and may be received and stored from the server of the mobile communication company that the receiver is using.

The number receiving unit 130 receives a telephone number input from a transmitting terminal where call connection is completed. Call connection may be performed using an external communication network or a communication server / switch. The number receiving unit may transmit to the transmitting terminal a guidance message for inducing the sender to enter a telephone number through the transmitting terminal. At this time, the guide message may be, for example, 'Please enter the existing phone number of the number you want to receive information, please press #'. At this time, the guide message may be guided by voice or text. The telephone number entered by the sender will then be the receiver's past number. This is because, if the current number can be entered, the call is directly connected to the called party, so there is no need to access the change phone number server.

The number information extracting unit 150 extracts the number information including the past number same as the received telephone number from the number information stored in the number storing unit. Thereafter, an identifier is assigned to each extracted number information. The identifier at this time consists of a code that can be input from the transmitting terminal and has sequentiality. Codes that can be input by the transmitting terminal refer to letters, numbers, symbols, and voices supported by the input apparatus of the transmitting terminal. For example, the identifier may be a number that can be combined with 0 to 9 assigned to a keypad provided as an input device of a transmitting terminal. In addition, since the identifiers have sequentiality, they may be sequentially assigned as 1, 2, 3, 4, 5,... The reason for configuring the identifier in this way is to allow the sender to select a desired identifier through the transmitting terminal.

The message transmitter 170 transmits a message including the user information included in each number information to which the identifier is assigned and the assigned identifier to the transmitting terminal. The transmission order at this time depends on the order of the identifiers. Even when a plurality of user information and identifiers are transmitted at once in the form of a text message, the arrangement order of each character follows the order of the identifiers. For example, if Identifier 1-User A, Identifier 2-User B, Identifier 3-User C, ..., then 1-A, 2-B, 3-C, ... You can send or create and send a text message that is integrated in the order 1-A, 2-B, 3-C, ...

The number guide unit 190 receives the selected identifier from the transmitting terminal and transmits the current number of the number information to which the received identifier is assigned in at least one of a text and a voice to the transmitting terminal. For example, when the sender selects 1 while 1-A, 2-B, 3-C, ... are transmitted, the current number of the number information to which the identifier of '1' is assigned is transmitted to the transmitting terminal. At this time, the current phone number of the selected A is XXX-XXXX. In addition to the current number, an additional announcement (except for XXX-XXXX) may be added and transmitted.

In order for the sender to select an identifier, a message including a user information and an identifier is transmitted by the message transmitter and the message must be displayed in voice or text on the transmitter. Since the selection of the sender will be made after the display of the message, the number guide can operate after the operation of the message transmitter.

On the other hand, when there are a plurality of recipients for the same past number, the receiver of the current number to which the sender wants to be generally informed is likely to be the recipient who has recently used the past number as the current number. Therefore, it is preferable that transmission of the message including the user information and the identifier made by the message transmitter is performed in the reverse order of time. At this time, the time may be a valid time point of the same past number as the telephone number input by the sender. Since the phone number is allowed to be used by only one user at a time point, the opening time or termination time of the corresponding phone number may be the valid time.

The number information may further include a valid time of each past number for the reverse order of the time, and the number information extracting unit 150 may assign the identifier in the reverse order based on the valid time of the same past number. This configuration allows the message transmitter to transmit the user information in the reverse order of time.

According to the above configuration, even if a plurality of recipients have used the same past number (past telephone number) in the past, the sender can be guided by selecting the desired recipient and changing the current number (current telephone number). This is useful when the same past number is used by multiple recipients, but may be advantageous in terms of recipient protection even when used by a single recipient.

Hereinafter, a configuration for receiver protection will be described.

According to the configuration described above, the sender can be easily informed of the current number, but the recipient may wish not to inform the specific sender of his or her current number.

To this end, the method may further include guide method information that is set to one of the manual guide or the automatic guide of the current number, wherein the number guide unit 190 is the number information to which the selected identifier is assigned when the guide method information is set to automatic guide. The current number of can be transmitted to the transmitting terminal. That is, in the state where the guidance method information is set to automatic guidance, the same operation as described above is performed.

If the guidance method information is set to manual guidance, the call number and the current telephone of the transmitting terminal are transmitted to the current number of the number information to which the selected identifier is assigned, without transmitting the current number of the number information to which the selected identifier is assigned. The number guide wish message can be transmitted. Although the sender has connected to the change phone number guidance server to be informed of the recipient's current number, the ultimate goal will be a call connection with the recipient. Therefore, it is possible to replace the guidance of the current number by informing the receiver that the sender desires to connect the call with the receiver, that is, the current telephone number guidance wish message. Recipients who have received the phone number wish message can optionally give the current number directly or attempt a direct call connection with the sender. Or no action can be taken.

The number guide unit may terminate the call connection with the transmitting terminal after transmitting the current number to the transmitting terminal or transmitting the current telephone number guide wish message to the current number (receiving terminal) of the number information to which the selected identifier is assigned. In the latter case, a message indicating that the current telephone number guidance wish message is transmitted to the receiving terminal before the call connection is terminated may be transmitted to the transmitting terminal.

The guide method information is set by the receiver, and the current phone number guide desired message may include at least one of a text message generated by the number guide unit or a voice message transmitted from the transmitting terminal. For example, the number guide checks the guide method information of the number information given the identifier selected by the sender, and if it is set manually, 'The recipient is manually checking the guide of the current phone number. Send the sender's caller's number to the user and end the call ?, and, depending on the sender's choice, there is a request for guidance of the current phone number from YYY-YYYY to the old number XXX-XXXX. A current telephone number guidance wish message in the form of a text such as. 'Can be sent to the receiver (receiving terminal). Or "The recipient is manually checking for instructions on the current phone number. If you leave the name and description of the sender and the telephone number to be contacted by voice, we will forward it to the recipient. 'And if the sender responds, the voice message left by the sender will be sent to the receiver (receiving terminal). Or "You have a request for guidance from your current phone number from YYY-YYYY to the old number XXX-XXXX. Please check the voice left by the sender 'along with the text message left by the sender. On the other hand, when the call number of the transmitting terminal is transmitted and displayed together with the calling party number service, 'YYY-YYYY', which is the call number of the transmitting terminal, may be omitted from the preceding announcement.

However, in this case, since the sender has confirmed the user information through the message transmitter, the sender can determine whether the receiver intentionally refuses the guidance. In such a case, it may be a problem when the sender has a malicious intention to the receiver, so that the message transmitter may not transmit the user information itself.

To this end, the number information further includes one or more rejected call numbers for rejecting the guidance of the current number, and the number information extracting unit 150 includes the number information including the same rejected call number as the call number of the transmitting terminal among the extracted number information. (Deny number information) may not be assigned an identifier. Of course, this requires the receiver to register the rejected call number as the number information in advance. If so, the message transmitter 170 targeting the number information to which the identifier is assigned does not transmit the user information of the rejected number information to the transmitting terminal.

As a result, it is difficult for the malicious sender to know the receiver's number change, etc., thereby protecting the receiver more effectively.

2 is a flowchart illustrating a method for guiding change phone numbers of the present invention, and the method for guiding change phone numbers shown in FIG. 2 may be described as an operation of the change phone number guide server shown in FIG.

First, a current number and user information of a receiving terminal, one or more past numbers and number information including valid time of each past number are stored (S 510). The recipient can access and register the change phone number server directly or be provided by a carrier. Even in the former case, it is advantageous to be provided by the carrier for the validity time of the past number.

After the call connection with the transmitting terminal receives the telephone number input from the transmitting terminal (S520). In the operation performed by the number receiving unit 130, the announcement for inducing the sender's telephone number input may be transmitted to the transmitting terminal.

One or more number information including a past number identical to the received telephone number is extracted from the stored number information (S530). If there is no number information extracted by the operation performed by the number information extracting unit 150, an error message may be transmitted to the transmitting terminal. If the number receiving unit already includes a configuration for sending the announcement to the transmitting terminal, the number information extracting unit may generate only the error message and transmit the generated error message through the number receiving unit.

For each of the extracted number information, a sequential identifier of a code input from the transmitting terminal is assigned in the reverse order based on the valid time point of the same past number (S541). The operation performed by the number information extracting unit 150 can provide convenience to the sender by assigning such an identifier.

According to the order of the identifier, a message including the user information of each number information to which the identifier is assigned and the assigned identifier is transmitted to the transmitting terminal (S550). As the operation performed by the message transmitter 170, the message may be transmitted in the form of voice or text. The various messages that appear after that may all be sent and received in this manner.

After the message is transmitted, the selected identifier is received by the transmitting terminal (S 560), and the current number of the number information to which the selected identifier is assigned among the number information to which the identifier is assigned is transmitted to the transmitting terminal (S 581). The operation is performed in the number guide unit 190 so that the sender is finally informed of the current number.

If considering the protection of the receiver, the following process may be added.

First, the number information further includes guide scheme information set to one of a manual guide or an automatic guide of the current number, and the step of transmitting the current number (S 560, S 581) comprises receiving an identifier selected by the transmitting terminal. In operation S 560, when the guidance method information is set to automatic guidance (S 580), transmitting the current number of the number information to which the selected identifier is assigned to the transmitting terminal (S 581). If set to guide (S 580), the call number and the current telephone number of the transmitting terminal are guided to the current number of the number information to which the selected identifier is assigned without transmitting the current number of the number information to which the selected identifier is assigned. And transmitting a desired message (S 583). According to this, if there is a transmitting terminal that wants to receive its current number, the receiver can directly determine and carry out call connection with the sender or guidance of the current number by checking the call number of the calling terminal or the current phone number request message. It becomes possible. In this case, the current phone number guide wish message may include at least one of a text message generated by the number guide unit or a voice message transmitted from the transmitting terminal.

On the other hand, the number information further includes one or more rejected call numbers for rejecting the guidance of the current number, and the step of assigning the identifier (S541) is the same as the call number of the transmitting terminal of the extracted number information rejection The identifier may not be assigned to the number information including the call number (S540).

As a result, the user information itself is not transmitted to a specific transmitting terminal, thereby effectively protecting the receiver.

In the above, the configuration and method for guiding the current number to the sender have been described. For reference, let's take a look at the registration process of number information.

3 (FIG. 3A, FIG. 3B) is a flowchart illustrating a change phone number registration method associated with the change phone number guide method of the present invention. For reference, steps except S 520 to S 583, S 603, and S 604 may be regarded as steps S 510 of FIG. 2.

For convenience of explanation, the call number of the transmitting terminal is set to '345678', the past number 1 of the receiving terminal to '123456', the past number 2 of the receiving terminal to '234567', and the current number of the receiving terminal to '456789'. The ID is set to '51913101' and the password is set to '31051912'.

First, the sender or the receiver makes a call to the representative phone (eg, 1588-7979) of the change phone number guide server (S601).

When the call connection is made, the change phone number guide server inquires whether the user wants to guide the current number or to subscribe (S602). For example, an announcement such as “Press 1 for subscriber number change” or “2” for subscriber registration ”can be sent to the calling terminal. The transmitting terminal described above would enter "1" and the receiving terminal would enter "2".

If the calling terminal is a calling terminal, i.e., a terminal that wants to guide the current number (change number), it inputs a telephone number before the change and sends a comment to input a special symbol "#" (S603), and the received number, for example For example, if "123456" is correct, "1" is wrong, and "2" is inputted to transmit a comment (S604). When the received number “123456” is confirmed, the current number guide step S 520 to S 583 of FIG. 2 is performed. Steps S 602 to S 604 described above may be included in step S 520 of receiving a telephone number input from a transmitting terminal in FIG. 2.

In step S602, if "2" is selected again, it is checked whether it is an existing subscriber or a new subscriber again (S605), and in the case of an existing subscriber, a service such as number modification / addition is provided / progressed (S606). At this time, the ID "51913101" and the password "31051912" set at the time of new registration may be requested before the number correction / additional service is provided.

In the case of a new subscriber, it is requested to set an ID (S 607), and checks whether the input ID is normally input (S 608). After that, it is checked whether a password setting request (S 610) and normal input (S 611).

It requests the input of the telephone number (past number) before the change (S 613), and if there is an input number (for example, "123456"), it checks whether it is normally input (S 614).

A request is made for inputting the use year of the past number (S 616), and it is checked whether the input year is normally input (S 617). The year of use can be entered automatically with the help of the carrier. To this end, the change phone number guidance server may have a means for retrieving the usage history of the past number from the carrier's server, or may have a means for requesting the carrier's server to transmit the usage history of the past number. have.

You can choose the year, month and day as appropriate.

After registering the year, a user name or a trade name of the past number is requested (S 619), and whether the input history is normally checked (not shown). At this time, the user name or trade name of the past number may be included in the user information of the number information.

Then, it is checked whether there is an additional number to be input (S620), and if there is a past number to additionally input a past number (for example, "234567") according to the user's selection, it is requested to be (S621). The procedure for additionally entered past numbers is the same as in S 614 to S 620.

After that, the user is notified of the charge and checks the user's progress (S 622), if not want to proceed to the service input termination (S 623) and ends. Step S622 may be performed immediately before step S607 or just before step S613.

Next, a request is made for inputting the current telephone number (current number) to be guided (S 624), and it is checked whether the input is normal or not (S 625).

For the guidance method, a request is made to select whether the user wants to confirm whether or not the user wants to confirm whether the voice message (text message is also possible) before the guidance (S 627). In the former case, the number information may include manually set guide method information, and in the latter case, the number information may not include guide method information or automatically set guide method information. If it is set manually, it is requested to input a phone number to receive a voice message, that is, a current phone number guide wish message (S 628), and check whether it is normally input (S 629) (S 630). In operation S 628, if there is no selection, the current number input by S 624 may be selected. On the other hand, in step S628 it is possible to guide the information on the charge when using the current telephone number guide wish message.

Subsequently, a request is made to input a mobile phone number for which payment is to be made (S 631), and it is checked whether it is normally input (S 632). S 631 and S 632 may be omitted when a separate payment method is provided.

After that, the payment amount is guided (S 633), and the authentication number is used to prevent the joining of another person's name (S 634), and a confirmation explanation is performed as necessary (S 635).

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.

It can be applied to a server that informs the receiver's changed telephone number at the sender's request.

In particular, it is advantageous to apply when there are a plurality of recipients who have used the previous telephone number requested by the sender.

It is also advantageous to apply to servers and systems that do not inform the recipient of a changed telephone number for a sender that the recipient does not want.
