The present invention relates to a method for automatically updating information of a mobile communication terminal. Particularly, when a first subscriber stored in a mobile communication terminal requests a call attempt or an SMS transmission, the telephone of the first subscriber is connected when the first subscriber connects to a server of an exchange. The present invention relates to a method for automatically updating information of a mobile communication terminal for automatically updating information (telephone number, etc.) stored in the mobile communication terminal when a number is changed and call forwarding occurs.

In the conventional mobile communication terminal or a terminal for other communication purposes, when the telephone number information of the first subscriber requesting the call is changed, a call transfer occurs in the server on the exchange side, and the first subscriber changed according to the call transfer. The phone number was connected.

1 is a flowchart illustrating a call processing procedure of a conventional exchange side server that handles a call request. The exchange side server checks the validity and the like by using a telephone number of a first subscriber (receiving subscriber) to which a calling party requests a connection. And, the first subscriber is set to be connected to the changed phone number using a service, such as call transfer when his phone number is changed.

When the phone number of the first subscriber is changed and the call transfer service is set as described above, the calling subscriber may hear a voice message for informing that the call transfer from the switching server is performed.

However, in the related art, when the telephone number of the first subscriber (receiving subscriber) requested by the calling subscriber is changed, a call forwarding guidance voice message is heard and the changed first subscriber telephone number is known. There was an inconvenience of having to save it manually in his terminal.

In addition, the call transfer performance guide voice message is output by using a TTS (Text To Speech) function, etc. from a specific exchange side server, the sound quality is not good, there was an unclear inconvenience.

 Accordingly, the present invention has been made to solve the above-described conventional problems. When the first subscriber stored in the mobile communication terminal requests a call attempt or an SMS transmission, the server of the switchboard connects the first subscriber to the first subscriber. It is an object of the present invention to provide a method for automatically updating information of a mobile communication terminal for automatically updating information (telephone number, etc.) stored in the mobile communication terminal when a phone number of a subscriber is changed and call forwarding occurs. have.

The present invention for achieving the above object comprises the steps of using a mobile communication terminal to the first subscriber (receiving subscriber) a call to transmit the receiving subscriber information to the switching server; Determining whether an information change request message is transmitted from an exchange side server according to the received subscriber information; Receiving the information change request message, the calling terminal is characterized in that it comprises the step of retrieving the information of the subscriber before the change, and updating the changed new information contained in the message.

In addition, the present invention provides a method, comprising the steps of: a server receiving a receiving subscriber information transmitted from a calling terminal, retrieving the information and determining whether the receiving subscriber information is valid; If the receiving subscriber information is invalid, obtaining valid receiving subscriber information corresponding to the receiving subscriber information; And performing a call establishment procedure based on the acquired new subscriber information, and generating and transmitting an information change request message to the calling terminal.

The present invention relates to a method for updating information stored in a mobile communication terminal. When requesting an arbitrary subscriber (first subscriber) stored in a calling mobile communication terminal to request a phone call or an SMS transmission, the exchange side server receives the request. When the phone number information of the first subscriber is changed, call forwarding is performed to a new phone number, and the renewed telephone number of the first subscriber is automatically transmitted to the calling mobile terminal. The main idea is to provide a way to make it possible.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, when the exchange terminal server attempts to make a phone call from the calling terminal, if the phone number of the calling terminal is changed and the phone number requested by the calling terminal is not valid, the switching server performs a call transfer to a valid phone number of the called terminal. In response to the call transfer, the telephone number of the changed receiver terminal is transmitted to the calling terminal.

Accordingly, the calling party terminal of the present invention corresponds to the changed phone number and the change request of the called terminal received from the switching server, the information of the called terminal subscriber (phone number information) stored in the phone book of the calling terminal. ) Is automatically renewed with a new phone number.

According to the present invention, the changed telephone number and the change request transmitted from the switching end server to the calling terminal are transmitted at the start of the telephone connection or at the end of the telephone connection and are processed by the terminal (calling terminal).

2 is a flowchart illustrating a call processing procedure of an exchange side server for processing a telephone request according to the present invention. As shown in the figure, the left side of the figure shows an operation flowchart of the calling terminal side, and the right side of the server side of the switching side server. An operation flowchart is shown.

The operation of the terminal side according to the present invention is as follows.

First, when a user attempts to make a phone call (or SMS) with a first subscriber (receiving subscriber) using a mobile terminal, when a user tries to make a call to a receiving subscriber's telephone number stored or directly inputted in the terminal, the user exchanges with the mobile terminal. The receiving subscriber's telephone number is sent to the one-side server.

Thereafter, the terminal determines whether a change request is transmitted from the exchange side server according to the received subscriber telephone number transmitted as described above, and receives the change request information as follows.

Here, the change request information is specific request information transmitted from the server to the calling mobile terminal when the receiving subscriber's telephone number stored in the calling subscriber's mobile terminal and the receiving subscriber's telephone number (change telephone number) to be actually connected are inconsistent. Indicates. This change request information has a structure as shown in FIG.

Receiving the change request information, the calling terminal searches for the telephone number of the receiving subscriber before the change and updates it with the changed new subscriber's telephone number.

In FIG. 2, a call is established after such an update procedure, but the update procedure and the call establishment procedure may be simultaneously performed because there is no priority of mutual time order. In addition, the update procedure may be performed at the end of the call.

Next, the operation of the exchange side server according to the present invention will be described.

The server retrieves the subscriber subscriber telephone number transmitted from the calling terminal and acquires the corresponding subscriber information to perform the following series of operations.

That is, a mobile switch center (MSC) plays a role of connecting actual calls, where the server is a system for storing subscriber information in a large database, and the server is a home location register (HLR). May be a system that is performed independently, it may be a system that performs a separate function in conjunction with the location register.

When it is determined that the receiving subscriber telephone number has been changed, that is, when it is determined that the telephone number of the receiving terminal received from the calling terminal is invalid, the server acquires a valid receiving subscriber telephone number corresponding to the receiving subscriber telephone number, and FIG. It generates the change request information as shown in 3 and transmits it to the terminal (calling terminal) requesting the call connection.

At this time, the server side obtains a valid telephone number, generates a change request information, and then transmits the priorities to the process of connecting the valid subscriber subscriber number with time. However, the priorities of each of these processes are meaningless. Do.

Therefore, the change request information may be transmitted to the terminal when the call is connected, when the call ends, or during the call.

FIG. 3 is an exemplary view showing a configuration of an information change request message transmitted from an exchange server to a calling terminal according to the present invention. Referring to FIG. 3, a command code is used to give a terminal a specific command, which is interpreted by the terminal. Thus, a certain command corresponding to the command code is executed by the main control unit MSN of the terminal.

Next, the sender ID and the receiver ID mean an identifier of a server to which the change request information is sent and an identifier of a terminal to be received. The before-change subscriber telephone number is an invalid receiving subscriber telephone number, and this before-change subscriber information can be used as a KEY value for retrieving telephone numbers stored in the calling terminal.

However, since the terminal has information on the telephone number of the receiving subscriber who has requested the current reception, it is not necessarily information to be transmitted. The changed subscriber's telephone number is a valid receiving subscriber's telephone number and must be transmitted as the telephone number to be updated corresponding to the subscriber's telephone number before the change.

At this time, the embodiment of the present invention has been described by illustrating only the subscriber's telephone number, it can be obvious to those skilled in the art that it can be used for a variety of information, such as user nickname, e-mail address.

As described above, when the mobile communication user changes the phone number from time to time, the method for automatically updating information of the mobile communication terminal of the present invention is automatically performed by the calling subscriber who requests such a call without manually inputting the changed phone number into the terminal. By updating to, there is an effect to eliminate the hassle required to change information such as a telephone number.
