1 is a block diagram illustrating a structure of a mobile communication system according to a preferred embodiment of the present invention.

Referring to FIG. 1, a mobile communication system 110 is provided for providing a mobile communication service to subscribed mobile communication terminals, and includes a mobile switching center 112, an equipment identity register (EIR) 114 A subscriber management server 116, a home location register (HLR) 118, and a Short Message Service Center (SMSC) 120.

The mobile switching center 112 transmits and receives signals and data to and from the mobile terminal 100 through the base station and performs voice call, additional service control and call setup for the terminals, and interworks with the HLR 118, If the destination terminal is registered in the call forwarding service, the call or message request from the originating terminal is transmitted to the terminal requested to be forwarded.

Here, the mobile switching center 112 may be a Mobile Switching Center (MSC), a Serving GPRS Supporting Node (SGSN), or a Wideband Mobile Switching Center (WMSC) according to the second and third generation communication methods.

The EIR 114 determines whether or not the USIM card is installed in the existing user terminal when the location registration request is received from the mobile terminal 100 in which the USIM card 102 is installed in the mobile switching center 112, To the subscriber management server (116).

That is, in the EIR 114, an eigenvalue assigned to each terminal hardware includes an International Mobile Station Equipment Identity (IMEI) serving as an ESN of CDMA and a subscriber distinguishing number used in call processing in the mobile communication system, It is possible to determine whether the USIM card is attached to an existing user terminal or another terminal through comparison of IMSI (International Mobile Station Equipment Identity) serving as a MIN of CDMA.

As described above, the EIR 114 manages the terminal information related to the change of the user's arbitrary device. When the USIM card is illegally attached to another terminal when the terminal is lost and is used, the EIR 114 blocks the illegal use of the mobile communication service have.

The subscriber management server 116 determines whether or not the mobile communication service is permitted according to the change of the device of the USIM card. If the subscriber management server 116 permits the provision of the mobile communication service, the subscriber management server 116 transmits all mobile communication service information , Incoming / outgoing call information, call detail information, message, data downloading and uploading history information to the terminal equipped with the USIM card and simultaneously stored in the subscriber management server 116.

In addition, the subscriber management server 116 stores the call forwarding information provided from the existing user terminal to the call forwarding terminal, thereby providing the call forwarding information stored at the time of canceling the call forwarding to the existing user terminal. In addition, the mobile communication services used in the call forwarding terminal can be detected and stored so that the existing user terminal user can check whether or not to download the information used in the call forwarded terminal from the mobile switching center 112 When the user performs a request for downloading the requested message, the mobile terminal 100 transmits the information transferred from the subscriber management server 116 and the information used in the called terminal to the existing user terminal .

That is, since the subscriber management server 116 is interworked with the mobile switching center 112, it is possible to store the calling and incoming call history information, the call history information, and the data transmission / reception history information of the terminal for which the data storage is requested through the mobile switching center 112 It is possible. And then transmits the information stored by the request of the mobile switching center 112 to the specific terminal.

The HLR 118 provides terminal subscriber information according to a terminal information request of the mobile switching center 112. For example, the HLR 118 may include location information of the terminal, information on whether to subscribe to the supplementary service, And provides the switching information to the mobile switching center 112. [

The SMSC 120 transmits a message to the MS according to a request from the MSC 112. The MSC 120 transmits information on a destination MS to receive a call or a message requested by the originating terminal to the HLR 118, And if the called terminal is registered as the call forwarding, it can be provided to the existing called terminal that a call or message has been sent to the terminal to be forwarded. In other words, when the call destination is changed due to the fact that the existing call destination terminal is turned on but the user is far away, the existing call destination terminal can be notified by text messages such as "years, months, days, .

In this way, since only the call forwarding is reported in the past, when the call forwarding is canceled, all the information forwarded to the call forwarding terminal can be received by the existing called terminal.

2 is a flowchart illustrating an operation procedure of a mobile communication system when a USIM card is installed in another terminal according to a preferred embodiment of the present invention.

2, when the user turns on the power after the USIM card is inserted into the other terminal 200 from the existing user terminal in step 202, the other terminal 200, to which the USIM card is attached, The mobile switching center 112 transmits an access signal for location registration to the mobile switching center 112 of the EIR 114 in step 204. In step 204, Request an IMEI check to determine if it is going to change.

That is, the USIM card stores MSISDN (Mobile Station International ISDN Number), IMEI, IMSI and other related information, and transmits IMEI and IMSI values to the mobile communication system when requesting location registration. In step 204, the IMEI and the IMSI value transmitted by the terminal for location registration are compared with the IMEI and IMSI values stored in the EIR database. In the case where the USIM card is installed in the existing user terminal in the same case, It may be determined that the card is mounted in another terminal.

Since the IMEI value is a value assigned to the mobile communication subscriber when the IMEI value is assigned to the hardware of the terminal, when the USIM card is installed in another terminal, the IMEI value transmitted from the terminal is an IMEI value The EIR 114 inquires of the subscriber management server 116 whether the USIM device is allowed to be changed in step 206. [

The subscriber management server 116 determines whether the USIM device is allowed to be changed. The subscriber management server 116 can manage the stolen terminal as black and the normal terminal as white, You can manage it together.

If the device is allowed to be changed, the device transmits white to the EIR 114 in step 208, requests the update of the IMSI and the IMEI value of the terminal on which the USIM card is currently mounted, and in step 210, And performs information management on the information. That is, by storing all the mobile communication service information used through the terminal equipped with the USIM card, when the user reinserts the USIM card in the existing user terminal, the stored mobile communication service information can be provided to the existing user terminal have.

However, if the subscriber management server 116 does not allow the USIM device to be changed in step 208, it transmits a black message to the EIR 114.

If the message received from the subscriber management server 116 is white, the EIR 114 updates the IMSI and IMEI values in the EIR database and transmits a white message to the mobile switching center 112 in step 212. However, when the black message is received, the mobile communication terminal directly transmits the black message to the mobile switching center 112.

The mobile switching center 112 transmits to the terminal 200 whether or not it can transmit and receive a black or white message received from the EIR 114 or transmits the received black or white message to the terminal 200, The mobile communication service can be used on the display of the terminal 200 because it is possible to transmit and receive a call when the mobile terminal 200 receives white. And the mobile communication service can be used immediately. However, when a black message is received, a call such as "service is not available"

Therefore, the user can confirm the availability of the mobile communication service after the location registration by attaching the USIM card to the existing user terminal or using another terminal.

3 is a flowchart illustrating a procedure of storing mobile communication service information using a USIM card according to a preferred embodiment of the present invention.

Referring to FIG. 3, in step 300, when a user installs a USIM card in another user terminal, the other user terminal performs location registration with the mobile switching center 112, and the mobile switching center 112 The EIR 114 requests the IMEI to check the location registration request from another user terminal equipped with the USIM card. In step 302, the EIR 114 checks whether or not the device in which the USIM card is inserted is changed, and transmits a device change confirmation message to the subscriber management server 116. In the subscriber management server 116, The mobile communication system determines whether to store the mobile communication service information generated while the user is using the mobile communication terminal with the USIM card inserted in the mobile communication system.

That is, as a mobile communication service used in another terminal, it is determined whether or not to store call history details, call detail information, message transmission / reception information, data transmission / reception information, etc. in the subscriber management server 116, The mobile terminal sets the terminal to store all of the mobile communication service information used through the changed terminal in the USIM card.

Although it is impossible to store all mobile communication service information with a small capacity of a conventional USIM card, a large capacity USIM card having a storage space of a gigabyte is developed, so that the data capacity stored in the USIM card is not a particular problem .

Accordingly, all of the mobile communication service information used in the terminal can be stored in the USIM card, and the terminal can store the data in the terminal 1) simultaneously with the terminal and the USIM card, 2) only in the terminal, and 3) The user can select whether or not to store the mobile communication service.

If the USIM card is re-installed in the existing user terminal in step 308, the mobile communication terminal inquires whether to provide the mobile communication service information stored in the USIM card to the existing user terminal in step 310 or performs automatic transmission to the existing user terminal, The user can use the information used through the other terminal after the USIM card is installed in the existing user terminal without any additional procedure.

If the mobile communication service information to be used by the user is set to be stored in the mobile communication system in step 304, the mobile communication service information used on the changed terminal in step 312 is transmitted to the subscriber management server 116 And store it together.

If the location registration is performed in the mobile communication system after the user moves the USIM card from the other terminal to the existing user terminal in step 314, the mobile switching center 112 of the mobile communication system proceeds to step 316, When the user requests download of the information stored in the mobile switching center 112, the subscriber management server 116 receives the stored information from the subscriber management server 116 in association with the mobile switching center 112, To the user terminal.

Of course, when the automatic setting is performed, the USIM card is installed in the user terminal, and after the location registration is performed, the subscriber management server 116 automatically receives the stored information without selecting the user.

4 is a flowchart illustrating a procedure of storing mobile communication service information according to call forwarding according to another preferred embodiment of the present invention.

4, in step 400, the user registers the call forwarding on the mobile communication system to perform call forwarding from the first terminal to the second terminal. In step 402, the mobile communication system transmits the first In step 404, when a call request to the mobile station is a call request, the subscriber information and supplementary service information of the first terminal are interworked with the HLR in the mobile exchange, In case of a message transmission request to the first terminal, the mobile switching center / SMSC checks the first terminal information through interworking with the HLR.

If the first terminal is currently in the call forwarding state to the second terminal, the mobile switching center simultaneously stores the mobile communication service information, which is forwarded from the first terminal to the second terminal during the call forwarding period, on the subscriber management server . That is, the caller information, the call history information, the incoming message information, and the like that are redirected from the first terminal to the second terminal while performing the existing call forwarding service and the calling information, the call history information, Information, transmission / reception data, and the like are managed by the subscriber management server.

And all mobile communication service information used through the second terminal by performing call forwarding can be stored in the subscriber management server.

This is maintained until the call forwarding is released in step 408. If the call forwarding is released, the mobile switching center interlocks with the HLR to check whether the mobile communication service of the first terminal can be performed, If it is possible, the mobile communication service information stored in the subscriber management server is transmitted to the first terminal in step 410.

That is, since the first terminal requests the location registration to the mobile exchange after the call forwarding is canceled, the mobile exchange checks the status of the first mobile terminal and transmits data information for a period of using the second mobile terminal, Or not.

(E.g., a download request) to the first terminal user, thereby receiving the mobile communication service information from the subscriber management server. On the other hand, if the user has previously set the automatic download of the used mobile communication service information after the call forwarding on the mobile communication system, the first terminal performs the automatic download of the mobile communication service information after the cancellation of call forwarding.

As described above, according to the present invention, data to be transmitted / received when a call is transferred between terminals or when a USIM card is inserted into another terminal is stored in a storage unit of a mobile communication system, .

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention.
