The present invention relates to a method for changing a number and allowing a subscriber to be provided with a mobile communication service without failing to access a network to a mobile communication terminal whose telephone number is changed as described above.

The vast majority of users have subscribed to certain carriers' mobile services, allowing them to make and receive calls anytime, anywhere. On the other hand, each mobile communication service provider provides a mobile phone terminal number change service as one of additional services. For example, subscribers whose mobile phone numbers are exposed to others may change their mobile phone numbers to new phone numbers, for example, when they are reluctant to receive a call from another person or when they switch to another service. There are often cases.

In general, in order to change the mobile phone number of subscribers, subscribers visit a terminal agency on-line and fill out various documents and apply for a mobile phone number change. Accordingly, the terminal distributor staff injects a new telephone number into the subscriber's mobile terminal to set the telephone number. In addition, the employee accesses the Customer Oriented Information System (COIS) using a computer installed in the terminal distributor and inputs the subscriber's requirements through a predetermined authentication procedure to change the mobile phone terminal number.

As described above, the subscriber's mobile communication terminal telephone number is changed to the home location register (HLR) in accordance with the change of the subscriber's mobile communication terminal telephone number previously stored in the customer information system by the input of the terminal agent. Pass the facts and the new telephone number so that the subscriber information of the home location register changes. Accordingly, when the mobile communication terminal is turned off, the mobile communication terminal accesses the mobile communication network with a new phone number and finishes registering the terminal location in the home location register to receive the mobile communication service.

However, in the offline mobile communication terminal telephone number change method as described above, the subscriber has to visit the terminal agency directly, and the subscriber himself or herself must prepare various documents reflected in the terminal agency. In addition, the terminal distributor staff must also access the customer information system and enter various items such as personal information and mobile terminal information on the web page, and then monitor the processing result of the customer information system. Changes can't be processed quickly.

The present invention has been proposed to solve the above problems and to meet the above demands, and the subscriber enters a new phone number into the mobile communication terminal through the customer information system without visiting the existing offline terminal distributor. It is an object of the present invention to provide a method for enabling the mobile phone terminal number to be changed and for allowing the subscriber to receive the mobile communication service without failing to access the network to the mobile terminal having the telephone number changed as described above.

In accordance with the registration of the new phone number of the mobile communication terminal in the register characterized in that the connection between the customer information system and the mobile terminal is released.

In addition, the method of the present invention includes a method for changing a telephone number in a mobile communication terminal, the method comprising: storing a new telephone number when a new telephone number is received from a subscriber according to the telephone number changing mode; Accessing a customer information system through a preset telephone number change URL and requesting a telephone number change using the stored new telephone number as a parameter; And when the connection with the customer information system is released as a result of the telephone number change request, setting the stored new telephone number as the terminal telephone number and rebooting the terminal.

On the other hand, according to another method of the present invention, in the method for changing the mobile communication terminal telephone number in the home location register, when the location information registration request signal is received from the mobile communication terminal side, the telephone number (MIN) inserted into the location information registration request signal is received. Querying the device number (ESN); Authenticating whether the mobile terminal subscriber is authorized to change a telephone number if the telephone number / device number inquiry result does not match the telephone number registered in the subscriber service profile; Requesting a customer information system to change a mobile communication terminal telephone number by using the telephone number and the device number as parameters if the telephone number change authority is the result of the subscriber authentication; And registering the new telephone number as the mobile terminal telephone number and registering the mobile terminal location information when receiving a new telephone number change success response from the customer information system as a result of the telephone number change request.

In addition, another method of the present invention, in the mobile communication terminal telephone number change method in the customer information system, when receiving a telephone number change request signal from the home location register (MIN) inserted into the telephone number change request signal And querying whether the telephone number can be registered using the device number (ESN) as a parameter; And if it is possible to register as a result of the telephone number inquiry, changing the mobile communication terminal telephone number for the device number to the telephone number and notifying the home location register of the telephone number change success.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 is a configuration diagram of an embodiment of a mobile communication network to which the present invention is applied.

As shown in FIG. 1, a mobile communication network to which the present invention is applied includes a mobile communication terminal 10, a base station 11, a base station controller 12, a packet data serving node 13, a home location register 14, and a customer. An information system 15. In addition, the mobile communication network further includes well-known basic components such as a mobile communication switching center, an SMS center, etc. for providing a mobile communication service (call / receive, SMS, etc.) to the mobile communication terminal 10.

In the present invention, the subscriber enters the desired new phone number directly into the mobile communication terminal 10, accessing the customer information system 15 with the existing phone number as a parameter, the new phone with the existing phone number Allows you to change to a number.

To this end, the subscriber receives a request for changing the mobile communication terminal telephone number through a predetermined authentication procedure through a web (wafer) site or a customer center of the customer information system 15 in advance. Accordingly, the customer information system 15 activates only that the subscriber can change the mobile terminal's telephone number without receiving a new telephone number from the subscriber [authorizes the change of the telephone number], and accordingly the mobile terminal ( If there is a request to change the phone number from 10), it is handled.

In the customer information system 15, mobile communication terminal telephone numbers of all mobile communication subscribers are managed. When the customer information system 15 is requested to change the new phone number from the mobile communication terminal 10, the customer information system 15 inquires a DB (not shown) and responds to the mobile communication terminal 10 whether the new phone number can be registered. In the customer information system 15, the subscriber's existing telephone number is changed to a new telephone number, updated in the DB, and the changed new telephone number of the subscriber is transferred to the home location register 14, and the home location register 14 is then updated. The new telephone number allows the subscriber to provide mobile communication services.

In particular, when the changed mobile communication terminal telephone number is registered in the home location register 14, since the mobile communication network resources previously allocated to the mobile communication terminal 10 are released, the new phone number is registered at the home location register 14. It is preferable that the connection between the customer information system 15 and the mobile communication terminal 10 be released. Therefore, in the mobile communication terminal 10, when the connection with the customer information system 15 is released after making a request for a new phone number change, the phone number change is regarded as successful. Complete the phone number change process.

In general, a mobile communication terminal is equipped with a telephone number setting mode (aka NAM (Number Assigned Module) mode). By the telephone number setting mode, the subscriber can inquire terminal information, for example, a mobile identification number (MNI), an electronic serial number (ESN), and the like, and designate and set a new telephone number.

By applying the phone number setting mode as described above, in the present invention, the mobile communication terminal 10 accesses the customer information system 15 using the preset phone number change URL as a parameter while storing the new phone number input from the subscriber. When the new telephone number change request is made, and the connection with the customer information system 15 is released, the terminal sets the terminal telephone number to the new telephone number and reboots.

2A and 2B are flowcharts illustrating an embodiment of a method for changing a mobile communication terminal phone number according to the present invention, and FIG. 2A illustrates a process of changing a new phone number inputted by a subscriber to a mobile communication terminal on a mobile communication system. 2B is a flowchart illustrating an embodiment of the present invention, in which a subscriber's mobile communication terminal telephone number is not properly changed in FIG. 1 is a flowchart illustrating a process of changing a terminal phone number.

First, the subscriber requests to change the mobile phone terminal number (ie, mobile terminal) through a predetermined authentication process through a web (wafer) site or customer center of the customer information system 15 before changing the mobile phone terminal number. Request for service to be authorized to change telephone number). Thus, through the linkage between the customer information system 15 and the home location register 14, the subscriber's service profile is activated to change the mobile terminal's telephone number, thereby granting the subscriber the right to change the telephone number (200).

Thereafter, the subscriber selects a phone number change mode installed in the mobile communication terminal 10 and inputs a new phone number desired by the subscriber to the mobile communication terminal (201). Here, the subscriber may designate a new telephone number in a state in which the mobile telephone directory is inquired through the Internet in advance and the telephone number is not assigned to another person.

Accordingly, the mobile communication terminal 10 starts the telephone number change process with the customer information system 15 while storing the new telephone number received from the subscriber in the memory (preferably in a nonvolatile area) (202). . At this time, the mobile communication terminal 10 is set to match the existing telephone number (MIN # 1) and ESN, the new telephone number (MIN # 2) received from the subscriber is additionally inserted into the terminal information field and stored.

In the meantime, the mobile communication terminal 10 is a base station 11, a base station controller 12, and an existing telephone number (MIN # 1) and an ESN as parameters by means of a preset telephone number change URL. It connects to the customer information system 15 via the packet data serving node 13 (203). Here, the mobile communication terminal 10 is connected to the mobile communication network using the existing phone number as a parameter because the new phone number is entered by the subscriber, not set, and received from the mobile communication terminal 10 in the mobile communication system. It checks the existing phone number (MIN # 1) and ESN and performs mobile terminal authentication to provide mobile communication service. On the other hand, the process of the mobile IP address allocation process in the known packet data serving node 13 will be omitted.

Then, the customer information system 15 queries the existing telephone number (MIN # 1) and ESN received from the mobile communication terminal 10 through the DB to perform subscriber authentication (204). At this time, the customer information system 15 authenticates whether the subscriber corresponding to the existing telephone number (MIN # 1) and the ESN has been authorized to change the telephone number.

If the subscriber is authorized to change the phone number as a result of the subscriber authentication, the customer information system 15 sends a subscriber authentication success response to the mobile communication terminal 10 (205). On the other hand, if the subscriber is authorized to change the phone number as a result of the subscriber authentication, the customer information system 15 sends a subscriber authentication failure response (for example, notification of not receiving a mobile phone number change) to the mobile communication terminal 10. It is preferable.

Then, when the mobile terminal 10 receives the subscriber authentication success response, the mobile terminal 10 transmits the previously stored new telephone number (MIN # 2) to the customer information system 15 to change the mobile terminal number of the subscriber. Request 206.

Accordingly, the customer information system 15 searches for all mobile communication terminal phone numbers stored in the DB using the new phone number MIN # 2 received from the mobile communication terminal 10 as a parameter, and checks whether registration is possible. (207).

If a new telephone number (MIN # 2) can be registered as a result of the telephone number inquiry, the customer information system 15 replaces the existing telephone number (MIN # 1) registered in the subscriber's service profile with the new telephone number (MIN #). 2), the mobile communication terminal telephone number is updated (208). On the other hand, if the new telephone number (MIN # 2) is not registered as a result of the telephone number inquiry, the fact that the customer information system 15 fails to register the new telephone number to the mobile communication terminal 10 (eg, a phone already given to another person) Number, please enter another phone number, etc.). As such, the new telephone number (MIN # 2) entered by the subscriber is often not registered. Accordingly, the subscriber may repeatedly enter another telephone number to be notified of the registration. Therefore, as mentioned above, the subscriber can reduce the packet fee burden by sufficiently checking the new telephone number (MIN # 2) desired by searching the mobile phone book in advance.

The customer information system 15 transmits the subscriber's changed new telephone number MIN # 2 to the home location register 14 and registers the subscriber's mobile communication terminal telephone number as the new telephone number MIN # 2. (209). As such, as the subscriber's mobile communication terminal telephone number is registered as the new telephone number (MIN # 2) in the home location register 14, the mobile communication terminal later uses the new telephone number (MIN # 2) and the ESN as parameters. The mobile communication network can be accessed.

Accordingly, the home location register 14 sends the telephone number registration success response to the customer information system 15 after completing the registration of the new phone number (210), whereby the customer information system 15 receives the new phone on the mobile communication system. Recognizing that the number change is normally performed, the connection with the mobile communication terminal 10 is released (211). At this time, the customer information system 15 releases the connection with the mobile communication terminal 10 according to the registration of the mobile communication terminal new telephone number in the home location register 14, but the mobile communication terminal telephone number is substantially the new phone number. Since the resources allocated to the home location register 14 as the existing phone number MIN # 1 are released, the connection between the customer information system 15 and the mobile communication terminal 10 is naturally released.

Subsequently, the mobile communication terminal 10 sets a new telephone number (MIN # 2) when the connection with the customer information system 15 is released as a result of the request for changing the new telephone number. And rebooting process (power off => power on) 212. In this case, the mobile communication terminal 10 preferably stores the details separately without discarding the existing phone number MIN # 1 even if the new phone number MIN # 2 is set as the mobile communication terminal phone number.

After this, when the rebooting process is completed, the mobile communication terminal 10 passes through the base station 11 and the base station controller 12 using the known terminal location information registration process, that is, the new phone number MIN # 2 and the ESN as parameters. Terminal location information is registered in the location register 14 (213, 214). Thereafter, the subscriber is provided with a mobile communication service (eg, making / receiving a call, wireless Internet connection, etc.) using the mobile communication terminal 10 having the changed telephone number.

On the other hand, when the connection with the customer information system 15 is released, the mobile communication terminal assumes that the phone number is normally changed in the mobile communication system and sets the terminal phone number to a new phone number after rebooting. Attempt to connect to mobile phone number by phone number.

However, when the subscriber's mobile communication terminal telephone number is not properly changed on the mobile communication system, for example, the connection between the customer information system 15 and the mobile communication terminal 10 is not released by changing the telephone number, but the mobile communication terminal. When the data channel of the wireless network section of (10) is an error or when the new phone number registration process is not properly performed in the home location register 14 interworking with the customer information system 15, the mobile communication terminal may be a home location register. Attempt to access the mobile communication network by setting a new phone number according to the response of the customer information system 15 instead of (14), but the terminal authentication fails by the base station 11, the base station controller 12 and the home location register 14 It may not be able to provide a mobile communication service to the subscriber. Accordingly, the process of processing such a case by further including a separate process in the home location register 14 is disclosed in FIG. 2B.

When the mobile communication terminal 10 receives the new phone number change success response from the customer information system 15, the mobile communication terminal 10 sets the mobile phone terminal number as the new phone number MIN # 2 and performs a rebooting process (see FIG. 2A). 212).

Afterwards, upon completion of the rebooting process, the mobile communication terminal 10 requests registration of terminal location information from the base station controller 12 via the base station 11 using the new telephone number MIN # 2 and the ESN as parameters (250). .

Then, the base station controller 12 uses the known terminal authentication process, that is, the new terminal number (MIN # 2) and ESN received from the mobile communication terminal 10 as parameters to the home location register 14 terminal authentication and terminal Request location information registration (251).

Accordingly, the home location register 14 inquires the subscriber service profile and inquires whether the new telephone number (MIN # 2) and the ESN received from the mobile communication terminal 10 are normal (matched) (252).

If the telephone number for the ESN of the subscriber service profile does not match the new telephone number (MIN # 2) received from the mobile communication terminal 10 as a result of the telephone number and the ESN inquiry (that is, the changed mobile terminal telephone number is Unregistered), the home location register 14 checks whether the subscriber has been authorized to change the telephone number (has already received the change of the mobile communication terminal telephone number) (253). On the other hand, if the telephone number for the ESN of the subscriber service profile matches the new telephone number (MIN # 2) received from the mobile terminal 10 as a result of the telephone number and the ESN inquiry (that is, the changed mobile terminal number is changed). Properly registered), the terminal location information registration process is normally performed between the home location register 14 and the mobile communication terminal 10 as in the process of "260" and "261" which will be described later.

When the subscriber is authorized to change the telephone number as a result of the telephone number change authority inspection, the home location register 14 receives the new telephone number MIN # 2 and the ESN received from the mobile communication terminal 10 and the customer information system ( And transmits to the subscriber's mobile communication terminal telephone number (254). On the other hand, if the subscriber is not authorized to change the telephone number as a result of the telephone number change authority check result, the home location register 14 regards the mobile terminal 10 as a duplicate terminal and ends the terminal location information registration process. The mobile communication service is prevented from being provided to illegal users (255).

Accordingly, the customer information system 15 searches for all mobile communication phone numbers stored in the DB using the new phone number MIN # 2 received from the home location register 14 as a parameter and checks whether registration is possible. (256). On the other hand, the new telephone number (MIN # 2) is changed in the customer information system 15 by the process after "207" in FIG. 2A, but it is confirmed whether there is a new telephone number processing omission in the customer information system 15. It is preferable to proceed again to the following process to be described later.

If a new telephone number (MIN # 2) can be registered as a result of the telephone number inquiry, the customer information system 15 is an existing telephone number (MIN # 1) registered in the service profile of the subscriber or a new telephone number that has been changed. Is changed to the new telephone number (MIN # 2) received from the home location register 14 to update the mobile communication terminal telephone number again (257). The customer information system 15 then responds (258) to the home location register 14 that the new phone number change was successful.

Accordingly, the home location register 14 registers the subscriber's mobile terminal number as a new telephone number (MIN # 2) in response to the successful response of the new phone number change, and thus the terminal location information of the mobile terminal 10. Register (259).

Then, the home location register 14 transmits the terminal location information registration success response to the base station controller 12 together with the terminal authentication success response (260). Accordingly, the base station controller 12 notifies the mobile communication terminal 10 that the terminal location information registration is normally performed in the state of recognizing the terminal authentication success (261). Thereafter, the subscriber is provided with a mobile communication service (eg, making / receiving a call, wireless Internet connection, etc.) using the mobile communication terminal 10 having the changed telephone number.

On the other hand, the method of changing the mobile communication terminal phone number disclosed in FIG. 2B described above does not require the subscriber to access the customer information system and change the phone number through the procedure disclosed in FIG. In response to the subscriber's rebooting procedure by entering a new phone number directly into the mobile communication terminal without changing it, the mobile communication terminal telephone is interlocked with the home location register and the customer information system by the mobile terminal location information registration process. It will be readily apparent to one skilled in the art that the number can be changed.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

The present invention as described above has the effect that the subscriber can easily and quickly change the mobile phone number through the customer information system by entering a new phone number to the mobile terminal without visiting the existing offline terminal distributor have.

In addition, the present invention has an effect that can prevent the mobile communication terminal set to the new phone number to fail the network connection due to the change of the subscriber's mobile terminal number is not properly made in the mobile communication system.
