1 is a block diagram schematically illustrating a structure of a mobile communication network for a number change service according to a preferred embodiment of the present invention.

Referring to FIG. 1, the mobile communication network 110 includes a mobile switching center (hereinafter referred to as MSC) 112, a home location register (hereinafter referred to as HLR) 114, and an automatic answering system ( Auto Response System (hereinafter referred to as ARS) 116, a text message center (hereinafter referred to as SMSC) 118, and a number change service server 120.

The MSC 112 transmits and receives signals and data to and from the mobile terminal 100 through a base station, performs voice call and additional service control of each terminal, and sets up a call, and the mobile terminal 100 and the number change service server ( 120) provides a connection function. In addition, when the calling terminal requests the call number before the change of the called terminal in conjunction with the HLR 114, the caller receives the called party information on the called terminal and matches the existing telephone number of the called terminal with the changed telephone number. To pass.

At this time, when the called terminal is a subscriber of the number change guide service, the defense change guide message is sent to the calling terminal through the ARS 116 and the SMSC 118, and when the called terminal subscribes to the automatic number change service, the number is changed. The service server 120 requests that the callback address message accessible to the number change service server 120 be transmitted to the calling terminal.

The HLR 114 may be called party's information, for example, called party's number change information, additional service subscription information, etc. according to the called party information request of the MSC 112. Whether or not to subscribe to the automatic number change service is provided to the MSC (112).

Meanwhile, in the present embodiment, the additional service subscribed to by the called party is separately presented as a number change guide service and an automatic number change service, but the two additional services are included as one additional service (eg, a number change). Plus service) is also available.

The ARS 116 notifies the calling terminal of the change of the number of the called terminal according to the request for sending the number change guide of the called terminal from the MSC 112, and sends a voice message indicating that the called is performed with the changed number. The SMSC 118 transmits the number change guide message of the called terminal to the calling terminal at the request of the MSC 112.

In the MSC 112, after the call connection between the calling terminal and the called terminal is terminated or when the calling terminal completes sending the text message by requesting sending a text message to the called terminal, the MSC 112 transmits the text message to the number change service server 120. A request for message transmission to the calling terminal is requested, and the number change service server 120 transmits a message including a callback address for automatically changing the number, that is, a message including an access address of the number change service server 120 to the SMSC 118. By requesting, the SMSC 118 transmits a callback address message for the automatic change of the number to the calling terminal.

When the calling terminal is connected through the callback address message transmitted from the SMSC 118 to the calling terminal, the number changing service server 120 may request "number automatic service execution request" and "number change history preview" to the connected calling terminal. , "Number change completion history", etc. to the calling terminal, "save the changed phone number as the calling terminal", if the address book server of the calling terminal in the mobile communication, "storing in the address book server", "calling terminal and Simultaneous storage in the server "and the like so that the calling terminal subscriber can select.

Accordingly, when the calling terminal subscriber selects a number change in the calling terminal, the number change service server 120 searches for a previous number address of the called terminal stored in the address memory area of the calling terminal and changes the address to the changed telephone number. After generating, by transmitting it to the calling terminal, the calling terminal downloads it, proceeds with the number change update, and transmits the number change completion message to the calling terminal.

On the other hand, the telephone number input by the user is stored in the address memory area 308 through the address scheme used for the address book. This may be different in each communication method, but the basic phone number storage method is the same for all terminals.

However, if there is a terminal having a different storage method for this, it is possible to check the information of the called terminal through the MSC 112 linked with the HLR 114, and change the number for the called terminal using a different storage method The service server 120 generates and transmits a command applicable to the corresponding terminal.

2 is a flowchart illustrating a number change service procedure in a mobile communication system according to an embodiment of the present invention.

Referring to FIG. 2, when the MSC 112 receives a call request or a message from the called terminal before the number change in step 200, and the MSC 112 receives the call, the MSC 112 determines the HLR 114 in step 202. Check the information of the called terminal through interworking with). Here, the checked information may be a changed telephone number of the called terminal and whether to subscribe to the additional service.

In this case, when the called terminal subscribes to the number change guide service and the number change service automatically, the MSC 112 requests the ARS 116 to send the number change guide voice message in step 204 and the number change to the SMSC 118. Request to send the announcement message. In this case, the MSC 112 may request both the ARS 116 and the SMSC 118 according to a system implementation scheme, or may request the sending of the announcement message only to either the SMSC 118 or the ARS 116.

Accordingly, the calling terminal recognizes whether the called terminal is changed in number, and waits for call connection and message completion. When the call connection is terminated and the message is completed, the MSC 112 requests the message for the number change to the number change service server 120 in step 206, and the number change service server 120 in step 208. The SMSC 118 transmits a message including a callback address for accessing the number change service server to the calling terminal.

In step 210, when the calling terminal accesses the number change service server 120 and receives a request to automatically change the number from the calling terminal, the calling terminal searches for the previous number of the called terminal stored in the address memory area of the calling terminal and changes the telephone number. By sending a command set to change to a number to the calling terminal, the calling terminal automatically changes the number. After the number change is completed, the change completion message is transmitted to the calling terminal to complete the number change.

In this case, by making the calling terminal access the number change service server 120 and transmitting or receiving data, the wireless access fee and the data sending / receiving charge may not be generated, thereby making it possible to easily use the automatic number changing service at the calling terminal. Let's do it.

3 is a block diagram briefly illustrating a structure of a sender mobile terminal according to a preferred embodiment of the present invention.

Referring to FIG. 3, the mobile terminal includes a control unit 300, a key input unit 302, a transceiver unit 304, a memory 306, an address memory area 308, and a display unit 310. do.

The key input unit 302 transmits a key input signal input through a keypad or a touch screen provided in the mobile terminal to the controller 300, and the transceiver 304 transmits and receives a message through data and signal transmission and reception with a mobile communication network. Performs transmission / reception, voice and video call connection.

The control unit 300 controls the respective functional blocks of the mobile terminal, performs a message transmission and reception request and call reception through the transceiver 304, and corresponds to the key input signal transmitted from the key input unit 302 Perform the command. For example, when an input signal for inputting and storing a specific telephone number is received through the key input unit 302, the controller 300 calls the input telephone number to the address memory area 308 in the memory 306. The number will be saved.

The memory 306 stores an application for driving the mobile terminal, data received from the transceiver 304, and data for transmitting data to another terminal to the transceiver 304 through the controller 300. do. In addition, the memory 306 may also store pictures, photos, call history, text and multimedia messages, schedules, and memos stored by the mobile terminal user. In particular, in the case of a phone book, the address memory in the memory 306 may be stored. Stored in area 308.

Therefore, when the control unit 300 of the mobile terminal receives a number update command for the specific telephone number transmitted through the mobile communication network, the control unit 300 searches for the specific telephone number in the address memory area 308 to search for the specific telephone number. By changing and storing the phone number included in the number update command in the address corresponding to the phone number, the mobile terminal user can change the number in the mobile terminal through a simple operation without having to find and modify the changed phone number of the called party. It is possible to allow this to be done automatically.

4 is a diagram illustrating a confirmation procedure of a message received by a calling terminal according to a preferred embodiment of the present invention.

Referring to FIG. 4, when the number change message 400 for automatically changing the called terminal number is received at the calling terminal, the number change service server 120 of the mobile communication network 100 is included in the number change message 400. Contains a callback address that allows access to the system. When the user clicks the access button, the calling terminal accesses the number change service server 120, and has a button for checking the change to be automatically updated and performing a number update on the connected screen 402.

Accordingly, when the user clicks on the number update, a command set for changing the number is downloaded from the calling terminal (404). In this case, the address memory area 308 in which the existing called party number is stored is searched by the downloaded number change command, and the address corresponding to the searched existing called party number is updated to the changed number.

5 is a flowchart illustrating a number change procedure in a calling terminal according to a preferred embodiment of the present invention.

First, the called terminal has changed its phone number, and has subscribed to the carrier's number change guide service to notify the change of the telephone number, and has been changed to the calling terminals that perform the call request and message transmission to the previous number of the called terminal. It will be described on the assumption that the user automatically subscribes to a number change service for automatically storing the phone number in the terminal.

Referring to FIG. 5, in step 500, when the calling terminal performs a call request to the existing phone number of the called terminal whose phone number is changed through the mobile communication network, the calling terminal changes the number through the mobile communication network before the call connection to the called terminal in step 506. The guide voice or text message is received at the calling terminal, and then the call is requested at the changed telephone number. In step 508, after the call connection ends, as shown in FIG. 4, the automatic change number message 400 is received by the calling terminal.

If it is necessary to send a text or multimedia message rather than a call request in step 500, the flow proceeds to step 502, and the calling terminal sends a text or multimedia message to the previous telephone number of the called terminal through the mobile communication network. In step 504, after receiving the number change guide message for the called terminal from the mobile communication network before sending the message, the message is transmitted to the called terminal through the changed telephone number. After the completion of the message transmission, the calling terminal receives the number automatic change message 400 from the mobile communication network.

If the automatic change of the number is performed through the automatic number change message 400 received in steps 508 and 504, the process proceeds to step 510 by clicking the access button of the automatic number change message 400 to change the number. Access to the change service server, and in step 512 receives a message for updating the number to the terminal from the connected number change service server. For example, 1) to check the change history in advance, 2) autosave to the calling terminal, 3) autosave only to the address book server, 4) autosave to the calling terminal and the server, the calling terminal may be provided, this The user can perform the auto-save of numbers through selective click.

In this case, if the automatic storage is not performed in the calling terminal, the process proceeds to step 514 to select the corresponding number to be automatically changed in the address book server of the mobile communication network. This may occur if the address book including the telephone number and the like previously stored only in the terminal, when the terminal is damaged or incapable of driving, data stored in the terminal is lost. Accordingly, in the mobile communication network, address book information is stored in a server, thereby making it possible to transmit and receive address book information at any time and to easily store address book information even when the terminal is replaced.

If the calling terminal user selects to store the number change in the terminal in step 512, the caller terminal changes the corresponding number in step 516. That is, the mobile terminal searches for the previous number of the called terminal stored in the address memory area of the calling terminal, downloads a command set to change the changed phone number from the calling terminal, proceeds with the update, and proceeds to step 518.

In step 518, the number change is completed by providing the calling terminal with a completion message according to the change of the number of the called terminal in the calling terminal or the server address book.

As described above, according to the present invention, after the caller requests a call to the called party whose telephone number is changed, or sends a text message or the like, the caller receives the number change guide message and the called party number automatic change message for the called party. In this case, through the confirmation of the message, the existing telephone number of the called party stored in the sender's mobile terminal is automatically changed to the changed telephone number.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.
