For example, requesting location information of the mobile communication terminal 70 to the home location register (HLR) 50 of the mobile communication terminal 70 (S110). In addition, the mobile terminal 70 receives location information (eg, a mobile switching center (MSC) identification number, etc.) of the mobile communication terminal 70 from the home location register (HLR) 50 (S115), and the memory reset command transfer message. The location information is included in the message, and the memory reset command transfer message is transmitted to the corresponding MSC 65 (S120).

Then, the mobile telephone switching center (MSC) 65 checks the mobile communication terminal 70 to which the memory reset command transfer message is finally transmitted, and then transmits the memory reset command transfer message to the mobile communication terminal 70 (S125).

Meanwhile, the mobile communication terminal 70 resets the memory in response to the memory reset command transfer message (S130). For example, all data in the memory area in which the personal information of the mobile communication terminal 70 is stored are deleted.

3 is a diagram illustrating a service flow for resetting a memory of a mobile communication terminal according to another embodiment of the present invention.

In order to operate such a system, as in the embodiment of FIG. For example, when the subscriber 10 who lost the mobile communication terminal, etc. calls the customer center 20 and requests a memory reset of the mobile communication terminal 70, the system operates. At this time, the customer center 20 checks the predetermined information (eg, social security number, address, telephone number, etc.) to confirm that the subscriber 10 has permission to reset the memory of the mobile communication terminal 70 (eg, mobile communication). It is preferable to perform a process of confirming whether or not the user is an actual user of the terminal 70 (not shown).

If the subscriber 10 is determined to be a user who has the authority to reset the memory of the mobile communication terminal 70, the customer center 20 transmits the memory reset request information to the customer information server 30, and the customer information server ( 30 generates a memory reset command transfer message destined for the mobile communication terminal 70 based on the memory reset request information and transmits the memory reset command transfer message to the message center 40 (not shown).

When the message center 40 receives the memory reset command transfer message of the mobile communication terminal 70 by the above-described processing (S105), the message center 40 receives the mobile communication terminal (the destination of the memory reset command transfer message). Request location information). For example, the home location register (HLR) 50 of the mobile communication terminal 70 requests the location information of the mobile communication terminal 70 (S110). The mobile terminal 70 receives location information of the mobile communication terminal 70 (eg, a mobile switching center (MSC) identification number, etc.) from the home location register (HLR) 50 (S115), and the authentication server 64. The unique information of the mobile communication terminal is requested to (S116). Here, the unique information of the terminal is hardware identification information uniquely held at different values for each terminal. In the present embodiment, for example, a device serial number (ESN) and an international mobile terminal identification number (IMEI). It is preferable to use a Mobile Station Identification Number (MSIN) value selected from one of: International Mobile Equipment Identity (IMI) and International Mobile Station Identity (IMSI).

Next, the message center 40 receives the unique information of the mobile communication terminal from the authentication server 64 (S117), includes the location information and the unique information of the terminal in the reset command delivery message, and then the message. To encrypt (S118). Subsequently, an encrypted memory reset command transfer message is transmitted to the corresponding mobile switching center (MSC) 65 (S120), and the location information is included in the memory reset command transfer message to correspond to the memory reset command transfer message. It transmits to the mobile telephone switching center (MSC) 65 (S120).

Then, the mobile telephone switching center (MSC) 65 confirms the mobile communication terminal 70 to which the memory reset command transfer message is finally transmitted, and then transfers the memory reset command transfer message to the mobile communication terminal 70 (S125).

Meanwhile, the mobile communication terminal 70 first decodes the received memory reset command transmission message (S126), and then compares the unique information of the mobile communication terminal included in the message with the unique information stored in the mobile communication terminal. If the two values match (S127), the memory is reset in response to the memory reset command transfer message (S130). For example, all data in the memory area in which the personal information of the mobile communication terminal 70 is stored are deleted.

Referring to Fig. 4, the memory reset command transfer message 80 used in the service of the present invention includes a caller ID 82 / receiver ID 84 / message type 86 / message content 88.

The caller ID 82 denotes an identification number of a caller who sends a memory reset command transfer message, and a receiver ID 84 denotes an identification number of a receiver who will receive the memory reset command transfer message. At this time, the caller ID 82 is an identification number of the message center, and the receiver ID 84 is preferably an identification number (for example, a telephone number, etc.) of the mobile communication terminal whose memory is to be reset.

The message type 86 is information for identifying whether the corresponding text message is a memory reset request message. Preferably, the message type 86 is expressed in two types, a control message and a general message. For example, in the case of the memory reset request message transmitted from the message center to the mobile terminal, the message type 86 preferably stores information for indicating that the message is a control message.

The message content 88 stores the actual content of the text message. For example, when the message is a message for transmitting a memory reset command, information indicating 'memory reset' is preferably stored.

First, when the mobile communication terminal receives a message through a communication network (S205), the mobile communication terminal determines whether the message is encrypted (S206), and the encrypted message decrypts the message (S207). Determine the type of message (S210). For example, the contents of the message type field included in the received message are checked to determine whether the message is a control message or a general message.

In operation S210, when the message type is determined, if the message is not a control message, that is, if the received message is a general message, the message is stored in the received message storage area (S235).

On the other hand, if it is determined in step S210 that the message type is a control message, it is checked whether the message is a memory reset command (S220). For example, check the message content field included in the received message to see if the message is a memory reset command.

When the received message is the memory reset command as a result of the checking (S220), the terminal unique information included in the received message is compared with the unique information stored in the terminal (S221). If so, the memory of the corresponding mobile communication terminal is reset (S225). If the received message is not a memory reset command as a result of the check (S220), a corresponding control command is performed (S230).
