The present invention relates to a call processing method requested to a receiver telephone number before a change in a mobile communication system. In particular, after a call originated to the receiver telephone number before a change is connected to a changed new receiver telephone number, It relates to sending the described message to the sender.

1 is a flowchart illustrating a call processing procedure requested to a receiver telephone number before change in a conventional mobile communication system.

When an outgoing call is first received through the base station to the exchange (step S110), the exchange retrieves and queries the location registration information in the HLR (Home Location Register) that manages the telephone location of the receiver terminal. If the HLR informs the exchange of the area where the receiver terminal is located (step S120), the exchange calls the receiver terminal simultaneously through all base stations in the area (step S130). In this case, a normal call is made, and if the call location of the receiver terminal cannot be determined by the HLR, only the subscriber of the service determines whether the receiver telephone number is changed (step S140). The exchange determines whether the telephone number has been changed by searching a database that records the terminal user's telephone number change history. If the receiver's telephone number is not the telephone number before the change, the call is no longer delivered to the receiver terminal and ends. Step S150), in this case, the voice announcement service is performed according to the mobile communication service provider. On the other hand, if the recipient's phone number is the telephone number before the change and the telephone number after the change is registered in the HLR, the telephone number after the change is attempted. In step S160, it is determined whether the call is a call. If the determination result indicates that the call is not a call but a text message, the text message is not delivered to the receiver terminal, and the procedure ends (step S120).

When the exchange connects a call to a new number, the announcement service is generally parallel. The announcement service at the exchange is provided by the access switching subsystem-Global Service (ASS-GS). do. The fixed type provides a fixed guide sound such as "Please check the telephone number you have just changed." 30 channels are accommodated and the edited type has a different tone, such as "Changed to xxxx." Four channels are allocated by providing. Examples of editable announcements include self number announcements, missed announcements, number change announcements, and call rejection announcements. Here, the 'number change announcement' service refers to a service that provides a voice for a predetermined period of time after a change to a calling subscriber who has changed the old telephone number when the phone number of the subscriber is changed.

However, the conventional number change guide service is a function that notifies the calling subscriber only the changed telephone number when a random calling subscriber attempts to reach the subscriber whose number has been changed, and the caller recognizes the telephone number after the change. There was a limitation, and the service content was extremely limited. In addition, when the caller transmits a text message (SMS, LMS, etc.) to the telephone number before the change (step 170), the text message is not automatically transmitted to the telephone number after the change, and thus the user's communication is frequently lost.

Accordingly, in order to solve the above problems, an object of the present invention is to provide a method for transmitting a text message and a multimedia message transmitted by specifying a telephone number before a change of a receiver to a telephone number after a change of a receiver.

Another object of the present invention is to provide a method of transmitting a call number change history of a receiver to a sender after connecting a call transmitted by designating a telephone number before the change of the receiver to a telephone number after the change of the receiver.

In order to achieve the above objects, according to an aspect of the present invention, when a call is requested to the telephone number before the change after the receiver telephone number is changed, the call signal is connected to the telephone number after the change, and the caller number change history is sent to the caller. In the mobile communication system for transmitting the number, the change number management database for managing the change of the recipient number and the change number telephone number after the change of the receiver is retrieved from the number change management database, and the changed after call number of the recipient is The present invention provides a mobile communication system including a server for transmitting to a message center to be transmitted to a caller's terminal and connecting the call to a telephone number after the call is changed.

In addition, when a call is requested to the telephone number before the change after the change of the receiver's telephone number, in a method of transmitting the telephone number after the change of the receiver to the caller in the mobile communication system by connecting the call to the telephone number after the change, Receiving the requested call from the telephone number before the change; retrieving a telephone number after the change of the receiver corresponding to the telephone number before the change from the number change management database; and calling the retrieved telephone number after the change. Transmitting the retrieved modified telephone number and the caller's telephone number to a message center for transmission to a terminal of the terminal; generating a message including the modified telephone number at the message center; Automatic connection of an originating call, characterized in that it comprises the step of transmitting a message. And a number of changes are proposed guidance method.

The method may further include checking whether the telephone number is registered in the HLR after the change and connecting the outgoing call to the changed new number if the telephone number after the change is registered in the HLR. Provided are a method for automatically connecting an outgoing call and a number change.

In addition, when the outgoing message is requested to the telephone number before the change after the recipient telephone number is changed, the method for transmitting the message to the telephone number after the change in the mobile communication system, the message received by the telephone number before the change received And retrieving a telephone number after the change of the receiver corresponding to the telephone number before the change from the number change management database, checking whether the telephone number after the change is registered in the HLR, and the telephone number after the change is HLR. If the registration is registered in the call signal automatic connection and the number change guide method further comprising the step of transmitting the message to the telephone number after the change is presented.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the apparatus and method for the automatic call signal connection and number change guide according to the present invention will be described in detail.

FIG. 2 schematically illustrates a configuration of a mobile communication system in which a method for automatically connecting an outgoing signal and guiding a number change according to the present invention is implemented, and a network interworking device (eg, an IWF or a gateway) connecting different communication networks. Etc.) and data communication devices (for example, PCF, PSDN, etc.) are omitted.

When the caller terminal 210 transmits an outgoing signal to the originating base station 220 (hereinafter referred to as a base station), the outgoing signal is transmitted to the exchange 230 via the base station 220. Here, the sender's terminal is a terminal capable of mobile communication and sending and receiving messages. The location registration information of the receiver terminal 290 to receive the forwarded call is retrieved from the HLR 240, and if the location registration information is not retrieved, the number is changed by retrieving the number change history from the number change management database 250. Determine whether or not. The number change management database 250 is a database in which the number change history is recorded when the telephone number of the user terminal is changed. In such a database, when the user changes the number of the terminal, it is desirable that the mobile operator automatically inputs and corrects the change number. The field that records the number change history is composed of the number field before the change, the new number field changed, and the date of the change field. If the telephone number of the receiver terminal 280 is determined to be the telephone number before the change as a result of retrieving the number change history from the number change management database 250, the telephone number after the change is retrieved from the number change management database 250 and extracted and changed. The outgoing signal is then sent to a telephone number, and the outgoing signal is transmitted to the receiver terminal 290 via the receiving base station 280. The role of retrieving and extracting the number change history from the number change management database 250 is in charge of the exchange 230 or a separate number change management server 260. If the number change management server 260 plays its role, the number change management server 260 receives the telephone number of the receiver terminal 290 from the exchange 230 and changes the number in the number change management database 250. After retrieving and extracting the details, the telephone number is transmitted after the change to the exchange 230.

When the number change history is retrieved and extracted from the number change management database 250 and delivered to the message center 270, the message center 270 generates a message describing the number change history and generates the message as the telephone number of the caller terminal 210. Send the message. Here, the message center 270 is composed of a plurality of message centers that are in charge of receiving and sending a message according to its function. In the present specification, the message center 270 is not divided for convenience of description. In addition, according to the types of messages to be processed, the message center is divided into a short message service center (SMSC), a long message service center (LMSC), and a multimedia message service center (MMSC). In the present specification, the message center 270 is collectively referred to.

In addition, a sales information database may be connected to the mobile communication system. The sales information database is a database in which a mobile operator inputs and manages subscription service information of a mobile subscriber. Here, it plays a role of managing information on whether the caller as well as the receiver subscribes to a service that automatically connects an outgoing call when a telephone number is changed and whether the subscriber subscribes to a service that receives a number change guide message. Accordingly, the exchange 230 or the number change management server 260 may search the sales information database to determine whether the sender and the receiver have subscribed to the corresponding service, and provide the corresponding service only to the subscriber.

In the above, the apparatus for performing the procedure of connecting a call number after changing the outgoing call designation by specifying the telephone number before the change and sending the change number in a message is described. However, it will be appreciated by those skilled in the art that the above functions may be implemented through a separate configuration device.

Hereinafter, a method for automatic call origination and number change guide according to a preferred embodiment of the present invention will be described. Methods for automatic call origination and number change guidance may be largely divided into a case of transmitting a call from a mobile communication terminal and a case of transmitting a message. In addition, it may be divided into a case of transmitting only the change number of the receiver for each call signal and a case of transmitting the change number after connecting the call signal to the changed new number. In addition, it may be divided into a case in which the exchange serves as a server for retrieving, extracting, and transmitting the number change history, and a case in which there is a separate number change management server. Embodiments in each case will be described in order below.

3 is a flowchart illustrating a method for automatic call connection and number change guide according to a first preferred embodiment of the present invention. A case where a call is received at a mobile communication terminal, the call is transmitted to a new number changed, and then the number change history is transmitted, and the switch serves as a server for searching, extracting and transmitting the number change history.

In step S310, a call is confirmed at the exchange that the recipient number is the number before the change. Here, the call call refers to a voice call call, the received call call is a call is confirmed that the receiver phone number is the telephone number before the change. The confirmation method has been described in detail in the step S110 to step S140 of Fig. 1 showing the prior art and will be omitted here.

In step S315, the exchange retrieves the number change history from the number change management database. In the step S140 of FIG. 1, the recipient number change history searched and extracted may be used. In this case, in order to continue using the number change history in a later-described step, it is preferable to record the extracted number change history in a storage unit such as an EEPROM. According to another embodiment, regardless of the result retrieved in step S140 of FIG. 1, the number change history may be retrieved from the number change management database and used as the result. According to another embodiment, step S140 of FIG. 1 and step S315 of FIG. 3 may be integrally determined to determine whether the number has been changed in the same step and to retrieve the number change history.

In step S320, the exchange extracts the number change history from the number change management database. The extracted number change details include the telephone number before the change, the telephone number after the change, and the change date.

In step S325, the exchange consults the HLR to determine whether the telephone number is registered in the HLR after the change. This is a measure to connect a call to the number if the phone number is registered in the HLR after the change. If it is determined that the telephone number after the change is a telephone number not registered in the HLR, all procedures are terminated in step S330.

In step S335, if the telephone number is registered in the HLR after the change, the exchange transmits the call to the receiving base station registered in the HLR by the general mobile communication method, and connects the call so that the receiver terminal can receive it. do. In this case, a message indicating that the receiver's telephone number has been changed by the voice announcement service and the telephone number after the change may be notified to the caller. In step S340, the connected call is terminated, and in step S345, the exchange receives the end signal of the call transmitted through the receiving base station.

In step S350, the exchange uses the calling party number to determine whether the calling terminal is capable of receiving a message. This is an action for transmitting a message in which the change number of the receiver is described to the caller's telephone number only when the caller's terminal can receive the message. Types of messages in which the number change details are described are short messages, long messages, and multimedia messages. The mobile communication terminal can basically receive a message. In the case of a landline phone, the mobile terminal cannot receive the message unless a special service is supported. Therefore, as a result of the determination, when the caller terminal cannot receive the message, all the procedures are terminated in step S355.

In step S360, when the caller terminal can receive the message, the exchange transmits the number change history to the message center. The number change history may be retrieved and extracted again from the number change management database, but it is preferable to use the result extracted in step S320. In this case, in order to continue using the result extracted in step S320, it is preferable to record the number change history extracted in a storage unit such as an EEPROM.

In step S365, the message center generates a message describing the received number change history. The contents to be included in the message must include the telephone number after the change, which is the main point, and the telephone number before the change, the change date, and the message that the change has been made. In step S370, the message generated in the message center is transmitted to the caller's telephone number.

In another embodiment, the procedure may proceed except for the procedure performed in steps S325 to S345. That is, without changing the call number transmitted by designating the old telephone number before the change, it is possible to send only the message in which the number change details are written to the caller without being connected to the telephone number. In another embodiment, the originating telephone number of the message generated and transmitted by the message center is the telephone number after the change of the receiver, and the caller who receives the message may attempt to make a voice call to the telephone number after the change of the receiver. The method of attempting a voice call is preferably a method in which a voice call is connected to a phone number after a change of a receiver when a call is pressed on a screen for checking a message.

In the above description, the flowchart for the automatic call connection and the number change guide is described by the exchange. Hereinafter, the flowchart performed by the separate number change management server will be described based on the difference from the above-described method.

4 is a flowchart illustrating a method for automatic call connection and number change guide according to a second preferred embodiment of the present invention. A call is received from the mobile communication terminal, the call is transmitted to the changed new number, and then the number change history is transmitted, and a separate number change management server searches for, extracts, and transmits the number change history.

In step S415, the exchange designates the telephone number before the change and receives the outgoing call, and then transfers the receiver telephone number to the number change management server. In step S420, the number change management server retrieves the number change history from the number change management database, and in step S425 it is extracted. In step S430, the telephone number is transmitted to the exchange after the change in the extracted number change details. In the subsequent step, as described above, the exchange connects the received call to the telephone number after the change, and receives a call termination signal when the call is terminated.

In step S470, when the exchange confirms that the calling party telephone number is registered in the HLR, the exchange transmits the calling party telephone number to the number change management server, and the received number change management server searches for the caller number and the number change management database. Send the extracted recipient number change history to the message center. Since the following process is the same as the above process, it is omitted.

In the above described the method for automatic call call connection and number change guide according to a preferred embodiment of the present invention. Hereinafter, after the outgoing message is automatically connected to the telephone number, a method for guiding a number change will be described based on the difference between the above-described method.

FIG. 5 is a flowchart illustrating a method for automatic message association and number change guide according to a third preferred embodiment of the present invention. A case in which an outgoing message is received in the mobile communication terminal, the outgoing message is transmitted to the changed new number, the number change history is transmitted, and the switch serves as a server for searching, extracting and transmitting the number change history will be described first.

The procedure performed in steps S510 to S530 is the same as the procedure performed in steps S310 to S330 in FIG. 3 except that the outgoing signal transmitted is an outgoing message. The outgoing message means a message excluding a call, such as a short message, a long message, and a multimedia message.

In step S535, the exchange transmits the telephone number and the outgoing message after the change of the receiver to the message center, and the received message center transmits the outgoing message by specifying the telephone number after the change of the receiver. Since the following process is the same as the case of automatic connection of the call, description thereof is omitted.

In another embodiment, the procedure may be performed except for the procedure performed in steps S540 to S560. That is, in the prior art, since there is no method of automatically transmitting an outgoing message to a phone number after the change, the outgoing message transmitted by specifying the old phone number after the change can be automatically transmitted to the phone number after the change and the procedure can be terminated. In another embodiment, the procedure may proceed except for the procedure performed in steps S525 to S535. That is, without changing the outgoing message sent by designating the old telephone number before the change to the telephone number, it is possible to send only the message in which the number change details are written to the caller. In another embodiment, the procedure performed in steps S525 to S535 may proceed after the procedure is performed in step S560. That is, after the message with the number change history is transmitted to the caller, the outgoing message transmitted by designating the pre-change phone number can be transmitted to the phone number after the change.

6 is a flowchart illustrating a method for message auto-connect and number change guide according to a fourth preferred embodiment of the present invention. A case in which an outgoing message is received from a mobile communication terminal, the outgoing message is transmitted to a changed new number, and then the number change history is transmitted, and a separate number change management server searches for, extracts, and transmits the number change history.

In step S615, the exchange designates the telephone number before the change and receives the outgoing outgoing message, and then transfers the recipient telephone number to the number change management server. In step S620, the number change management server retrieves the number change history from the number change management database, and in step S625 it is extracted. In step S630, after the change of the extracted number change history, the telephone number is transmitted to the exchange. In the subsequent step, as described above, the exchange transmits the outgoing message received to the telephone number after the change. Since the following process is the same as the above process, it is omitted.

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, the apparatus for automatically making an outgoing call and changing the number according to the present invention and the method transmit a call number, a text message, and a multimedia message transmitted by specifying a phone number before the change of the receiver to the phone number after the change of the receiver. After that, the present invention provides an apparatus and method for transmitting a change of a telephone number of a receiver to a sender in a message. Therefore, according to the present invention, when an outgoing subscriber attempts to make a call to a subscriber whose number is changed to a conventional number, the caller uses a message after the caller changes the phone number, out of the limit of notifying the calling party only by the changed phone number. It's easier to recognize. In addition, when the caller transmits a text message (SMS, LMS, etc.) and a multimedia message to the telephone number before the change, the message is automatically transmitted to the telephone number after the change, thereby preventing a loss in communication of the user.
