More specifically, FIG. 2 is a flowchart illustrating a procedure of acquiring MSISDN information of a charging target through a wireless automatic registration procedure when the MSSDN information does not exist in the UICC.

As shown in FIG. 2, the message used in the wireless automatic registration procedure according to the present invention may include a wireless automatic registration request message, a wireless automatic registration response message, and a wireless automatic registration confirmation message.

Referring to FIG. 2, if there is no MSISDN information in the UICC, the subscriber station 110 maps the wireless auto-registration request message to the SMS submit message defined in the 3GPP standard and transmits the message to the OTA registration controller 160 ( S210).

Here, the wireless auto-registration request message may include IMSI, IMEI, ICCID and OTA type information. In particular, the OTA type information is information for identifying that the SMS submit message is an OTA message for service opening, and is a predefined value between the mobile communication system and the subscriber station 110.

In particular, the above IMSI, IMEI, ICCID and OTA type information may be mapped to user data fields defined in the SMS submit message in order not to change the format of the SMS submit message defined in the 3GPP standard. May be separated using a predefined order and a space character.

When the OTA registration controller 160 receives the wireless auto-registration request message, the OTA registration controller 160 obtains MSISDN information corresponding to the IMSI received from the home location register 170 (S220), and includes the obtained MSISDN, OTA type, and IMSI value. The wireless auto-registration response message is transmitted to the subscriber station 110 (S230).

Here, the wireless auto-registration success message may be transmitted by mapping OTA type and IMSI information to a user data field defined in an SMS submit message. In this case, the OTA type and IMSI information included in the wireless auto-registration success message may be distinguished using a predefined order and a space character.

3 is a flowchart illustrating a service opening method of a WCDMA terminal according to an embodiment of the present invention.

Referring to FIG. 3, when a user presses a power button of the subscriber station 110 (S305), the subscriber station 110 initializes the mounted UICC 120 (S310).

In this case, the subscriber station 110 may extract at least one of IMSI, ICCID, IMEI, and MSISDN from a predetermined storage medium provided in the UICC 120.

In general, IMSI, ICCID, IMEI, and MSISDN are stored in a predefined address of a storage medium, and the subscriber station 110 transmits the corresponding information to the UICC (Cu interface between the mobile equipment (ME) and the USIM defined in 3GPP. 120).

The subscriber station 110 determines whether the MSISDN exists in the UICC 120 (315). Here, the subscriber station 110 may determine that the value of the acquired MSISDN is a predefined value (including, for example, NULL or 0) and the MSISDN does not exist.

As a result of the determination, when the MSISDN does not exist, the subscriber station 110 locks the functions corresponding to all bearer services except for the functions necessary for the wireless automatic registration procedure (S320). Here, the functions required for the wireless auto registration procedure may include some functions (eg, confirmation, cancellation, numbers, special character keys, etc.) of the terminal keypad, location registration for sending and receiving wireless auto registration messages, and SMS. It may include receiving and sending some SMS.

In general, the mobile communication system charges for a service provided through a specific bearer, so blocking the bearer service function before opening the service may have the effect of preventing unnecessary charges for the MSISDN for the unregistered IMSI. .

For example, the subscriber station 110 according to the present invention is an SMS except for sending a short message in which a protocol ID (hereinafter, referred to as a 'protocol identifier' (PID)) defined in an SMS submit message format is set to '0x7f'. The call function can be turned off.

That is, the subscriber station 110 may lock a key button and a MT (Mobile Terminated) / MO (Mobile Oriented) service which are not necessary for the WCDMA terminal service opening method disclosed in the present invention.

Thereafter, the subscriber station 110 transitions to a radio quality check state for measuring radio quality using a pilot signal received from the base station (S325). Here, the subscriber station 110 may determine whether to transmit a specific message by measuring the signal level of the received pilot and comparing the measured signal level with a predetermined reference level.

The subscriber station 110 may determine whether the subscriber station 110 enters an area in which service is impossible using the measured result of the received pilot intensity and the reference level (S330).

If it is determined that it is located in the in-service area, the subscriber station 110 performs a location registration procedure (S335).

For example, in the WCDMA network, the location registration procedure may include a Cell Update Message, a URA Update Message (URA) Update Message, and a Routing Area Update Message (RA) Update Message defined in the 3GPP standard. And a LA Location Area Update Message.

In particular, the subscriber station 110 uses the IMSI to transmit current location information of the subscriber station 110 using a mobile communication system (for example, a home location register) even when the MSISDN does not exist in the UICC 120 through a location registration procedure. And 170, and a Visitor Location Register.

In particular, if it is determined that the subscriber authentication for the corresponding subscriber station 110 is completed through the location registration procedure, the exchange 140 may provide a service required from the subscriber station 110 later. However, it should be noted that in a mobile communication system environment based on MSISDN, subscriber authentication using only IMSI may cause charging error.

The subscriber station 110 determines whether or not the location registration procedure succeeds (S340). If it fails, the subscriber station 110 releases the blocked function in step 320 (S345), and the location registration rejection reason. A predetermined user interface (hereinafter, referred to as a user interface (UI)) popup window may be output to the liquid crystal display (S350).

In step 340, if the location registration procedure is successful, the subscriber station 110 outputs a UI pop-up window "Please use after registering the number" on the liquid crystal display (S385), the locking idle state (Locking Idle State) It may transition to (S390).

Herein, the operation of the subscriber station 110 in the locked idle state will be described in detail with reference to FIG. 4.

In step 315, when the MSISDN exists in the UICC 120, the subscriber station 110 performs a location registration procedure (S355).

The subscriber station 110 determines whether the location registration has failed (S360). If the subscriber station 110 fails to register the location, the subscriber station 110 opens a predetermined UI popup window for each location refusal reason. The display may be output to the liquid crystal display (S365).

In step 360, when the subscriber station 110 successfully registers the location, the subscriber station 110 transitions to an idle state (S370).

In general, it is apparent to those skilled in the art that the subscriber station 110 which has transitioned to the idle state after successfully completing the location registration procedure may request various bearer services from the mobile communication system.

In step 330, if the subscriber station 110 enters an out of service area, the subscriber station 110 pops up a UI popup saying, "Service is not available because the signal strength is weak." The window can be output to the liquid crystal display. Thereafter, the subscriber station 110 transitions to the radio quality check state (S380).

4 is a flowchart illustrating a service opening method of a subscriber station in a locked idle state according to an embodiment of the present invention.

Referring to FIG. 4, when the state of the subscriber station 110 is in a locked idle state (S405), the subscriber station 110 may receive a subscriber number registration request signal from the user (S410). Here, the subscriber number registration request signal may be a signal generated when the user presses a confirmation button included in the UI popup window output in step 385 of FIG. 3.

When the subscriber station 110 receives the password input by the user through the predetermined UI (S415), the subscriber terminal 110 extracts the service opening password stored in advance (S420).

The subscriber station 110 compares whether the extracted service opening password and the received password are the same (S425).

As a result of the comparison, if the same, the subscriber station 110 after the transition to the radio quality check state (S430), and determines whether to enter the service unavailable area (435).

If it is determined that the subscriber station 110 is located in the serviceable area, the subscriber station 110 maps the wireless answering request message to the SMS submit message and transmits it to the mobile communication system (S440). At this time, the state of the subscriber station 110 maintains a lock idle state (S445).

In step 425, if the password input from the user is different from the service opening password, the subscriber station 110 outputs a UI pop-up window "Retry after checking the password" on the liquid crystal display. The process may return to step 415 (S450).

However, the subscriber station 110 may limit the number of password verification using a predetermined counter.

In step 435, when it is determined that the subscriber station 110 enters the unserviceable area, the subscriber station 110 outputs a UI pop-up window “The service is not available because the signal strength is weak” to the liquid crystal display. It may be (S455). Thereafter, the subscriber station 110 transitions to the radio quality check state (S460).

When the subscriber station 110 in the locked idle state receives the wireless auto-registration response message including the MSISDN (S465), the subscriber station 110 stores the received MSISDN in a predetermined recording area of the UICC (S470). . Here, the wireless auto-registration response message may be mapped to an SMS delivery message defined in the 3GPP standard and received by the subscriber station 110.

Thereafter, the subscriber station 110 transmits a wireless automatic registration confirmation message indicating that the MSISDN has been successfully received to the mobile communication system (S475), and automatically reboots the terminal (S480).

In this case, the wireless automatic registration confirmation message may be transmitted by being mapped to an SMS submit message defined in the 3GPP standard.

As shown in FIG. 3, when the MSISDN exists in the UICC, the subscriber station 110 transitions to an idle state when the location registration procedure succeeds, thereby transferring a desired service (for example, a bearer service) from the system. You can be provided.

Referring to Figure 4, after the power of the subscriber station 110 in the locked idle state (Power Off) (S485), when the power is connected again (Power On), the subscriber station 110 is described above. It can be seen that step 310 shown in step 3 is performed.

According to another embodiment of the present invention, it should be noted that the password verification procedure performed by steps 420, 425 and 450 may be performed by the mobile communication system.

For example, the subscriber station 110 may include the password inputted by the user in the wireless automatic registration request message of step 440 and transmit the password. Thereafter, the mobile communication system (which may be, for example, the OTA registration controller 160) may determine whether the received password matches the pre-stored service opening password.

If it is determined that the received password is different from the service opening password, the mobile communication system may transmit a wireless auto registration response message to the subscriber station 110 indicating that the wireless auto registration failed.

5 is a user interface for opening a service according to an embodiment of the present invention.

Referring to FIG. 5, when the power of the subscriber station 110 is connected and the MSISDN does not exist in the UICC, the subscriber station 110 uses a string 540 and a confirmation button "Please use after registering the subscriber number". The UI including 550 may be output to the liquid crystal display in operation S510.

When the user presses the confirmation button 550, the subscriber station 110 displays a UI including a string 560 of " Please enter a password ", a password input area 570, and a number registration button 580. The display may be output to the liquid crystal display (S520).

After the user enters a password in the password input field 570, where the password may consist of a combination of numbers, letters and special characters (which may be, for example, * 147359 * 682 *). When the number registration button 580 is pressed, the subscriber station 110 may output a UI including a character string 590 of "registering subscriber number" to the liquid crystal display (S530).

In step 530, the subscriber station 110 may reboot the terminal when registration of the subscriber number is successful.
