The present invention relates to a method and a system for transmitting caller personal information of a called terminal. More specifically, the called terminal which transmits the registered caller personal information input from the calling terminal to the called terminal so that the called terminal personal information can be known at the called terminal in the situation where it is not possible to answer the call due to absence, meeting, power off of the terminal, etc. Caller's personal information delivery method and system.

With the development of mobile communication technology and the expansion of subscribers, the service of mobile communication service providers is increasing day by day, and the telecommunication service providers develop and provide additional services considering various environments. Among these services, the wired / wireless telephone service provides additional services that enhance customer satisfaction through effective handling of missed calls, which enables the called party to check who is calling.

For example, a caller ID service that allows you to determine who made a call for an incoming call, a caller nickname service that allows you to send a simple text greeting, and a caller terminal power supply for incoming calls while the device is turned off. If it is turned on, there is a service that notifies you of the calling number, a voice mail service that records your message when the other party does not answer the call, and a service that delivers the caller's phone number as a text message.

The user who receives the missed call through the service checks the caller information on the missed call and attempts to recall the call. Therefore, the user checks the caller information on the missed call by considering the caller setting text information, the caller ID display information, and the information of the called terminal built-in phone book. However, in the missed call, there is a case in which caller identification is not possible using only the above-described information, and in this case, a work of verifying through a direct telephone call is required.

Here, a caller ID (CID) service is a service that displays the caller's telephone number on the called party's terminal (called party's telephone or display terminal) before or during the call.

The caller ID display service provided in the related art is provided in such a way that when a call is received, the caller terminal's telephone number is displayed on the called party's terminal or a screen preset by the called party is displayed in correspondence with the telephone number of the caller's terminal.

Here, the caller nickname indication service delivers the message set by the calling subscriber as additional information of the signaling message during the call setup process between the called exchange and the called terminal. The nickname service currently provided by the mobile communication terminal provides a message transmission service of about 16 bytes in consideration of the display of the terminal, and most of the users who subscribe to the service register a greeting that is not related to their personal information. I use it.

Therefore, the called party should be able to infer the caller for the incoming call by the caller's phone number by the calling number display service and the caller's name and nickname by the calling party nickname display service. However, if there is no relationship between the sender and the called party, there is a limit to obtaining information about the caller. Caller ID display service must identify the caller only by phone number, so it is difficult to determine who the caller is if the called party does not match the phone number stored in his terminal. In addition, when the caller uses a landline telephone of a private exchange that does not support the caller ID display function or is a call-only phone whose call is prohibited, it is impossible to determine or confirm who the caller is.

In addition, when the calling number display service and the caller nickname display service are used at the same time, personal information such as their name may be delivered to the nickname portion. However, the caller nickname display service is limited to only eight characters (16 bytes) in order to display one line on the LCD screen of the mobile communication terminal. Therefore, the called party must infer the caller for the incoming call by the calling user's phone number by the calling number display service and the caller's name by the calling nickname display service.

Therefore, if the information about missed calls is name and outgoing phone number, there is a relationship between caller and called party. If the called party can know exactly who the caller is by name and phone number, it is necessary to decide whether to make a call. You can have no problem with the phone call.

However, if the called party cannot identify the caller by the existing information alone due to a telephone call or a change of the phone number by an acquaintance or an existing person without any information, the called person is awkward and the phone number obtained by the calling number display service. The hassle of trying to check the calling user of missed call by trying to make a call. Otherwise, a situation arises where the missed call is ignored and the caller waits until the call comes in again. If the caller's call is important to the called party, the opportunity for the called party may be lost.

In order to solve this problem, the present invention provides a caller personal information delivery system of the called party that the caller can check the caller personal information of the caller in the situation that can not answer the call, such as missed or power off or the voice call is connected Its purpose is.

Another object of the present invention is to provide a method for registering and storing caller personal information input by a caller between mobile communication terminals, and transmitting specific DTMF information, call forwarding personal information of the called terminal upon incoming or outgoing call.

FIG. 2 is a flowchart illustrating a method of delivering caller personal information in a caller personal information transmitting system of a called party shown in FIG. 1 according to a preferred embodiment of the present invention.

The calling terminal 100 accesses the customer service server 130 through the mobile communication network 120 and registers the caller personal information display service provided by the content service provider through the homepage access through the wired Internet or the portal access through the wireless Internet access. do. The caller terminal 100 receives the caller personal information to be transmitted from the calling terminal 100 to the called terminal 110 through the user interface, and registers and stores it in the personal information server 132 of the customer service server 130 (S200). The personal information server 132 transmits and stores the registration information including the fact that the personal information is subscribed to the caller personal information display service of the calling terminal 100 to the customer information server 134 (S202). When the calling terminal 100 subscribed to the caller personal information display service attempts a voice call to the called terminal 110 (S204), the mobile communication switching center 129 stores the above-described registration information in the customer service server 130. Query the customer information server 134 whether the calling terminal 100 is subscribed to the caller personal information display service and receive a corresponding registration status response signal, and then request the call terminal 110 to set up a call. (S206, S208).

When the call setup is made to the called terminal 110, the called party receives a call and makes a voice call, and the general caller personal information display service is stopped. Of course, even for a successful voice call can be configured to check the caller personal information.

If the incoming call is not made due to the absence or other reasons of the called party, the incoming call setup is stopped, the connection attempt is made to the voice mailbox service, and the caller ends the service after leaving his or her message and phone number in the voice mailbox.

If the call is terminated by the missed call due to the absence of the called party, the mobile communication switching center 129 determines whether the calling terminal 100 is subscribed to the caller personal information display service, and if the call is subscribed to the service of the customer service server 130. The sender personal information is requested to the personal information server 132 (S210). Subsequently, the personal information server 132 converts caller personal information into a message form using a messaging system (SMS, MMS, email, etc.) to which the personal information server 132 is linked (S212).

2 is a case in which the missed call is not received, the caller's personal information is extracted from the customer service server 130 using the caller's telephone number as an identifier by using the calling number display service, and the extracted caller's personal information is received in the form of a message. The embodiment shows the transmission flow of the caller personal information display service output to 110.

If the caller uses a landline telephone on a private exchange that does not support the calling number display function, or uses a call-only telephone whose incoming call is prohibited, the called party cannot determine or confirm who the caller is. In order to prepare for this case, FIGS. 3 and 4 transmit specific DTMF (Dual Tone Multifrequency) information selected by the caller, request the caller personal information display service to the customer service server 130, and then receive the extracted caller personal information. The embodiment shows the transmission flow of the caller personal information display service output to the terminal 110. Here, FIG. 3 shows a transmission flow of a caller personal information display service occurring between a mobile communication terminal and FIG. 4 between a landline telephone and a mobile communication terminal.

3 is a diagram illustrating a method of applying a caller personal information display service to a call between a calling terminal and a called terminal according to a preferred embodiment of the present invention.

The calling terminal 100 accesses the customer service server 130 through the mobile communication network 120 and provides the caller personal information display service to the customer service server 130 through the homepage access through the wired Internet or the portal access through the wireless Internet access. The caller inputs personal information to be transmitted to the destination terminal 110 through the user interface of the calling terminal 100 and transmits it to the customer service server 130 to request the caller personal information display service (S300). At this time, the service subscriber is a specific telephone number and / or a special key inputted by the caller as the identifier to be retrieved from the database of the customer service server 130 to output the caller personal information to the called terminal 110, or the telephone of the calling terminal 100. You can specify the number.

Subsequently, the customer service server 130 transmits registration information indicating whether the caller personal information displaying service is subscribed to the HLR 127 using the caller personal information input and stored at the calling terminal 100 to the caller personal information displaying service. The subscription is notified to the HLR 127 (S302). Since the above-described registration information is also stored in the customer service server 130, it is possible to confirm in real time whether to subscribe to the caller personal information display service through a query to the customer service server 130.

Here, the caller personal information indicates the caller's name, work name, work phone number, phone number of the mobile communication terminal, memo and email address, and the like.

When a call is attempted from the calling terminal 100 to the called terminal 110, first, an outgoing call is requested from the calling terminal 100 to the calling mobile communication switching center through the wireless access networks 121 and 124 (S304). Subsequently, when the calling mobile communication switching center requests the location information of the called terminal 110 to the HLR 127, the HLR 127 receiving the location information of the called terminal 110 indicates whether to subscribe to the caller personal information display service. Send a location information response message including the registration information to the originating mobile switching center. The originating mobile telecommunication switching center requests a call establishment to the terminating mobile telecommunication switching center in order to set up a call (S308).

The terminating mobile communication switching center receiving a call setup request from the originating mobile telecommunication switching center generates a terminal paging message from the information included in the data terminating request signal and transmits it to the terminating terminal 110 through the mobile communication network 120 (S310).

Here, the paging message is a message indicating that the voice call or data call has arrived to the mobile communication terminal through the mobile communication network 120, one of a plurality of messages transmitted to the mobile communication terminal through the paging channel of the wireless channel.

When a call is not received at the destination terminal 110 for a predetermined time, the mobile communication system cancels the call connection, moves to an Automatic Response Service (ARS), provides a voice mailbox service, and provides a voice mailbox service. It can be configured to guide the use of the caller privacy information service.

Before the voice mailbox service is provided by the destination terminal 110 or while the voice mailbox service is provided, the originating terminal 100 receives a key selection signal selected by the caller, generates specific DTMF information, and then sends the message to the destination mobile communication exchange through the originating mobile switching center. Specific DTMF information is transmitted (S312). The originating / receiving mobile telecommunications exchange recognizes the termination information for the call connection when receiving specific DTMF information. Upon receiving the call setup failure signal, the incoming mobile telecommunication switching center receives a telephone number of the calling terminal 100 or a specific phone number and / or a special key inputted by the calling terminal 100 as an identifier as a customer service server 130. By sending the information to the caller personal information to the customer service server 130 (S314).

Here, the specific DTMF information is stored in the form of a shortcut key ("** + A's telephone number + *") input by the caller in the calling terminal 100, and the corresponding frequency signal is entered into the mobile communication switching center 129. The mobile communication switching center 129 decrypts the information, converts it into digital information, and transmits the converted information to the customer service server 130.

The customer service server 130 searches a database by querying a specific telephone number, a telephone number of the calling terminal 100, etc. inputted by the caller included in the above-mentioned identifier, extracts corresponding caller personal information, and then extracts the caller. Personal information is sent to the destination mobile communication switching center (S316), and the destination mobile communication switching center receiving the caller personal information is linked with a messaging system (not shown) to connect a specific signal message, a short message service (SMS) and a multimedia message service (MMS). And converts it into one message form and transmits it to the called terminal 110 (S318). In the method of displaying the caller personal information on the destination terminal 110, the caller personal information may be displayed in various ways such as e-mail and uniform resource locator (URL) information provided to the caller personal information in addition to a specific signal message, SMS, and MMS. It can be output to the called terminal 110.

If the caller inputs the specific DTMF information and the telephone number by the call indication is different, the above query word retrieves the caller personal information from the database of the customer service server 130 using the telephone number inputted by the specific DTMF information. To extract.

The messaging system refers to a system that generates one or more message types such as SMS, MMS, specific signaling message, URL information, and email.

In addition, even when a call is made to the called terminal 110 by an outgoing call request of the calling terminal 100 to enable a normal voice call, a caller personal information may be output to the called terminal 110.

The message received at the destination terminal 110 includes an existing call indication telephone number, a phone number entered by the user, caller personal information or URL information for accessing caller personal information.

If the calling party's calling number is not currently its own representative number, displaying the calling party's personal information based on the calling number may cause the called party to misrecognize the calling party in missed calls.

That is, when the caller A makes a call to the called terminal 110 of the called party B by the calling terminal 100 of the friend C, the telephone number of the calling terminal C is output to the called terminal 110 of the B and is a missed call. B does not know that A called.

Therefore, in the embodiment of the present invention, if A enters the calling terminal 100 in the form of a specific key ("** + A's telephone number + *") while waiting for a call and ends the call, the destination mobile communication switching center In the call waiting sound (RBT: Ring Back Tone) section and the caller B of the terminal 110 is converted from the telephone number of the C calling terminal 100 to the telephone number of the A calling terminal 100. Since the terminating mobile communication switching center stores which number the existing outgoing indication telephone number is delivered to, the existing outgoing indication telephone number is replaced with a new telephone number included in the caller's personal information in the incoming history of the called terminal 110.

In addition, in addition to replacing the existing caller ID number with a new phone number included in the caller personal information, the caller personal information is added and replaced as a whole, and the caller personal information or URL information received by the destination terminal 110 is replaced. The sender's personal information to access through is stored in the destination terminal (110).

4 is a diagram illustrating a method of applying a caller personal information display service to a call between a landline telephone and an incoming mobile communication terminal according to a preferred embodiment of the present invention.

The outgoing wired terminal (wired telephone) accesses the customer service server 130 through the outgoing wired telecommunication switching center through the gateway to provide the caller personal information display service through the homepage access via wired internet or portal access via wireless internet access. The server 130 requests the caller personal information display service by inputting the caller personal information to be transmitted to the called terminal 110 through the user interface of the calling wired terminal and transmitting the same to the customer service server 130 (S400). . At this time, the service subscriber is a specific telephone number and / or a special key or telephone number of the calling wired terminal inputted by the caller as an identifier to be retrieved from the database of the customer service server 130 to output the caller personal information to the called terminal 110. Can be specified. Here, the caller personal information indicates the caller's name, work name, work phone number, phone number and e-mail address of the mobile communication terminal.

When a call is attempted from the originating wired terminal to the called mobile communication terminal, a call is first requested from the originating wired terminal to the originating mobile communication switching center through a public telephone network (S402). The originating wired communication switching center receiving the outgoing call requests a call establishment for call connection to the destination mobile communication switching center through the gateway (S404).

The called mobile communication switching center receiving the call setup request from the originating wired communication switching center generates the called terminal paging message from the information including the data incoming request signal and transmits it to the called terminal through the mobile communication network 120 (S406). Here, the paging message is a message indicating that the voice call or data call has arrived to the mobile communication terminal through the mobile communication network 120, one of a plurality of messages transmitted to the mobile communication terminal through the paging channel of the wireless channel.

If the incoming mobile communication terminal does not receive the call for a certain time, the mobile communication system cancels the call connection, moves to the Automatic Response Service (ARS), provides the voice mailbox service, and provides the caller while providing the voice mailbox service. It can be configured to guide the use of the personal information display service.

The calling wired terminal receives the key selection signal selected by the caller and generates specific dual tone multifrequency (DTMF) information before or during the voice mail service from the receiving mobile terminal, and then uses the gateway through the calling wireline switching center. Specific DTMF information is transmitted (S408).

The gateway provides an interface for data exchange between the wireless communication system and the wired communication system and converts protocols, signals, and data into a form suitable for each network. In general, the gateway is directly connected to the mobile communication switching center 129 to connect a wired communication network and a wireless communication network.

When the originating wired communication switching center and the gateway receive the specific DTMF information, the originating wire communication switching center and the gateway recognize the termination information for the call connection.

Receiving the call setup failure signal, the gateway receives the telephone number of the calling wired terminal or the specific telephone number and / or special key inputted by the calling wired terminal as an identifier and transmits the caller to the customer service server 130. The personal information is requested to the customer service server 130 (S410). The customer service server 130 searches the database for a specific phone number included in the above identifier as a query to extract the corresponding caller personal information, and then transmits the extracted caller personal information to the destination mobile communication switching center through the gateway. (S412), the receiving mobile communication switching center receiving the caller's personal information is converted into any one message type such as a specific signaling message, a Short Message Service (SMS) and a MultiMedia Message Service (MMS) in conjunction with a messaging system (not shown). The call is transmitted to the called mobile communication terminal (S414). Here, the messaging system refers to a system for generating any one or more message types, such as SMS, MMS, a specific signal message, URL information, and email.

In addition to the specific signal message, SMS and MMS, the caller personal information is displayed on the called mobile terminal in various ways such as e-mail and Uniform Resource Locator (URL) information given to the caller personal information. Can be printed as In addition, even when a call is made to an incoming mobile communication terminal as a call request from the outgoing wired terminal, and a normal voice call is possible, a method of outputting caller personal information to the incoming mobile communication terminal is also possible.

In addition, displaying the caller personal information based on the calling number if the caller's calling number is not the current representative number may cause the called party to misrecognize the calling party in the missed call.

That is, when caller A attempts to make a call to the called mobile communication terminal of called party B using the calling wired terminal of friend C, the telephone number of the calling wired terminal of C is output to the called mobile communication terminal of B and is a missed call. Does not know that A called.

Therefore, in the embodiment of the present invention, when the caller A enters the calling wired terminal in the form of a specific key ("** + A's telephone number + *") while waiting for a call and ends the call, the called mobile communication switching center During the Ring Back Tone (RBT) period with B, the caller is converted from the telephone number of the calling C terminal to the telephone number of the calling C terminal. Because the terminating mobile telecommunications station stores which number the existing outgoing indication telephone number has been delivered, it replaces the existing outgoing indication telephone number with a new telephone number included in the caller's personal information.

In addition, the caller ID number is not only replaced with a new phone number included in the caller's personal information, but also by adding the caller's personal information as a whole, and through the caller's personal information or URL information received by the destination mobile terminal. The calling party's personal information to access is stored in the called mobile communication terminal.

5 is a diagram illustrating an example of caller personal information that is input and stored in a customer service server and displayed on a called terminal according to an exemplary embodiment of the present invention.

The caller personal information as shown in FIG. 5 is provided from the calling terminal 100 to the customer service server 130 and stored, and when the missed call occurs, the caller is outputted to the called terminal 110 and who is the caller who attempts to miss the call. In addition, the caller can easily determine the purpose of the call. The caller's personal information indicates the caller's name, work name, work phone number, phone number of the mobile communication terminal, memo, landline phone number and email address.

That is, in the existing caller display service, the caller information of the missed call could be confirmed through a preset script image corresponding to the caller's phone number, nickname information, and the caller's phone number. However, there are cases in which caller identification is impossible only with the above information. For example, if a caller uses a landline telephone on a private exchange that does not support caller ID display, or uses a call-only call that is prohibited from being called, the called party is unable to determine or verify who the caller is.

Therefore, as shown in FIG. 5, by providing caller personal information about the caller to the destination terminal 110, it is possible to prevent unnecessary phone calls due to unidentified callers and a situation of ignoring important calls. In addition, a simple photo or the like may be added to provide more accurate caller personal information in addition to those illustrated in FIG. 4.

Such caller personal information is output to the destination terminal 110 through a message means such as e-mail, SMS, MMS, so that the called party can confirm who the caller is, even if the caller does not confirm through the voice call, You will be able to determine if you have to. In addition, the present invention can be configured so that caller personal information can be confirmed even for an incoming voice call in addition to the missed call.

When the customer service server 130 receives the specific DTMF information or the caller's telephone number from the calling terminal 100, the customer service server 130 includes the specific telephone number included in the specific DTMF information input by the caller, the telephone number of the calling terminal 100, and the like. After searching the database with the query, extracting the corresponding sender personal information, and converting the sender personal information into a message form such as e-mail, SMS, MMS, etc. through a messaging system that interoperates the extracted sender personal information and transmits it to the destination terminal 110. In this case, caller personal information extracted from the customer service server 130 may be transmitted in a message form or URL information for accessing caller personal information may be generated and transmitted.

In this case, the URL information is the same as the URL with the hyper link in the body of the e-mail. When the user double-clicks the URL, the web browser of the external program is automatically started to connect to the home page of the designated URL. Refers to an address indicating the location of information on the map. The URL information in the present invention means that when the phrase "caller personal information" is output on the called terminal 110, when the called person clicks this part, the caller personal information is downloaded from the customer service server 130 and output. .

The telephone number of the caller provided by the existing caller ID service is used to change to a specific telephone number included in specific DTMF information input by the caller.

That is, the caller can easily obtain the caller personal information by outputting the caller personal information or URL information received from the customer service server 130 in association with the specific telephone number included in the specific DTMF information input by the caller.
