Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a network configuration of a terminal switching service system according to an embodiment of the present invention.

As shown in FIG. 1, the terminal switching service system according to the present invention includes a plurality of mobile terminals 110 and 120, switchers 130 and 140 in which the mobile terminals 110 and 120 are located, and the respective mobiles. Home location registers (150, 160) to accommodate the terminal (110, 120), terminal switching server 170 for controlling the terminal switching process, the International Mobile Station Identity (IMSI) and MSISDN (Mobile) of the mobile terminal (110, 120) Subscriber ISDN Number) includes a FNPS 180 for managing mapping data.

In FIG. 1, it is assumed that a mobile communication subscriber receives a mobile communication service by switching a terminal to the mobile terminal 110 while using the mobile terminal 120. Accordingly, the mobile terminal 120 is referred to as an existing mobile terminal, and the mobile terminal 110 is referred to as a switching target mobile terminal. The mobile terminals 110 and 120 may be applied without limitation as long as they are terminals capable of voice or video communication and text message transmission and reception. For example, PDA, cellular phone, PCS phone, GSM phone, W-CDMA phone, CDMA-2000 phone, MBMS phone, etc. are mentioned. Preferably, the switching target mobile terminal 110 may be a telematics terminal installed in a vehicle to provide a communication service.

In order to receive the communication service by switching the terminal from the existing mobile terminal 120 to the switching target mobile terminal 110, the mobile communication subscriber provides a service code indicating the terminal switching service to the switching target mobile terminal 110 (eg, * 120). ), And the phone number (ie, MSISDN) of the existing mobile terminal 120 to be switched and inputs a call button. Accordingly, the information of the existing mobile terminal 120 is deactivated in the mobile communication network so that incoming and outgoing calls of the existing mobile terminal 120 are prohibited and all call processing is performed through the switching target mobile terminal 110.

The mobile terminals 110 and 120 and the exchanges 130 and 140 are connected through a base station NodeB and a base station controller RNC, and the exchanges 130 and 140 process basic and additional services, and incoming and outgoing call processing of subscribers. It performs the function of location registration and handoff procedure, interworking with other networks such as public network or intelligent network system.

In particular, when switching the terminal, the exchange 140 blocks the incoming and outgoing call of the existing mobile terminal 120 by setting the service profile of the existing mobile terminal 120 to inactive. In addition, the exchange 130 changes the service profile of the switching target mobile terminal 110 to the service profile of the existing mobile terminal 120 and changes the MSISDN of the switching target mobile terminal 110 to the MSISDN of the existing mobile terminal 120. In this case, the incoming call to the existing mobile terminal 120 is transferred to the mobile terminal 110 to be switched. On the contrary, when the terminal switch is released, the switch 140 activates the service profile of the existing mobile terminal 120 and the switch 130 restores the service profile of the switch target mobile terminal 110.

On the other hand, after the terminal switch is made, the exchange 140 may block all outgoing calls from the existing mobile terminal 120, but may not block outgoing calls for a specific function. For example, when the terminal is switched to use the switching target mobile terminal 110 and the terminal is to be switched off, the existing mobile terminal 120 is blocked from making a call and the terminal can be switched off to the existing mobile terminal 120. It happens that you can't. Therefore, the exchange 140 allows the call transfer when the terminal switch release originating call is transmitted from the existing mobile terminal 120 so that the terminal switch release can be performed. Preferably, the exchange 140 stores and manages the function code information for the terminal switching release, and when the outgoing call including the function code is transmitted from the existing mobile terminal 120, the exchange 140 refers to the function code to perform the origination of the outgoing call. Allow.

The home location registers 150 and 160 are databases that store service profiles related to subscriber information of the mobile terminals 110 and 120, and include identification numbers (IMSI, MSISDN, etc.) and additional service information of the mobile terminals 110 and 120. Store and manage location information and information required for switching a terminal according to the present invention. Preferably, the home location register 160 of the existing mobile terminal 120, when the terminal switch is made, the switching display on the information of the existing mobile terminal 120, the switching unit 150 is the switching target mobile terminal 110 is located And / or store and manage information of a packet switched node (SGSN, not shown), and manage system data (GT information) of the home location register 150 accommodating the switching target mobile terminal 110. On the contrary, when the terminal switch is released, the home location register 160 of the existing mobile terminal 120 deletes the terminal switch information and restores the original. Meanwhile, the home location register 150 of the switching target mobile terminal 110 displays and manages that the terminal switching is made from the existing mobile terminal 120 in the information of the switching target mobile terminal 110 when the terminal switching is performed. . When the terminal switch is released, the home location register 150 deletes the terminal switch information. The terminal switching information stored in the home location register 150 of the switching target mobile terminal 110 is used when the switching target mobile terminal 110 registers a position in the terminal switching state.

The terminal switching server 170 stores and manages terminal switching service subscriber information and performs terminal switching service logic. That is, the terminal switch server 170 transmits a terminal switch command or a terminal switch release command message to the FNPS 180 according to the service code included in the message transmitted from the home location registers 150 and 160. In this case, the terminal switching server 170 includes the MSISDN of the existing mobile terminal 120 in the terminal switching command or terminal switching release command message.

The flexible number portability server (FNPS) 180 stores and manages IMSI and MSISDN mapping data of an existing mobile terminal, and receives the terminal switching command or the terminal switching release command message from the terminal switching server 170 and includes the same in the message. IMSI is searched using the MSISDN of the existing mobile terminal 120, and the MSISDN of the existing mobile terminal 120 included in the message is replaced with the searched IMSI and transmitted to the home location register to set the terminal switching or the terminal switching. To be done. Preferably, the terminal switch command or terminal switch release command message is an ATM (AnyTime Modification) message.

Although the terminal switching server 170 and the FNPS 180 are described as separate components in the present embodiment, the FNPS 180 manages the mapping data of the MSISDN and the IMSI of the mobile terminal, and thus the terminal switching server 170 and the FNPS 180. 180 may be integrated into one, and in this case, the FNPS 180 may be used only as a DB and perform the functions of the above-described FNPS 180 in the terminal switching server 170. Therefore, it should be understood that the terminal switching server in the following claims refers to a case where the terminal switching server 170 and the FNPS 180 of the present embodiment are integrated. However, for convenience of description, the following embodiments are assumed to be separately constructed.

2 is a flowchart illustrating a terminal switching service subscription process according to an embodiment of the present invention.

A mobile subscriber who wants to subscribe to a terminal switching service according to the present invention subscribes to a terminal switching service through an agency or a customer center. The mobile subscriber subscribes to the mobile terminal switching service by designating the mobile terminal 110 (MS1 in FIG. 2). In this case, a plurality of mobile communication subscribers may subscribe to a terminal switching to one switching target mobile terminal 110. For example, family members may designate one mobile terminal 110 (MS1 in FIG. 2) as the switching target mobile terminal 110 to subscribe to the terminal switching service.

When the mobile subscriber subscribes to the terminal switching service as described above, the customer information system (WISE) transmits the mobile terminal 120 and the home location register 160 (HLR2) to accommodate the mobile terminal 120 of the mobile subscriber. Information of the switching target mobile terminal 110, that is, IMSI and MSISDN is transmitted (S201). Then, the home location register 160 (HLR2) registers the terminal switching service setting information in the terminal information of the mobile subscriber (S203). In the drawing, only one mobile communication subscriber is described, but as described above, a plurality of subscribers may designate one switching target mobile terminal 110. In this case, the mobile terminal registers and transmits the mobile terminal information of the subscriber and the information of the switching target mobile terminal to the home location register that accommodates the terminal of each subscriber.

Next, the customer information system is connected to the home location register 150 (HLR1) which accommodates the mobile terminal 110 to be switched. Information is transmitted (S205). When a plurality of subscribers designate one switching target mobile terminal 110, the customer information system includes information MS1 of the switching target mobile terminal 110 and information of mobile terminals of the plurality of subscribers MS2 # 1 and MS2 #. 2, MS2 # 3, MS2 # 4 ...) are transmitted to the home location register 150 (HLR1) that receives the switching target mobile terminal 110. Then, the home location register 150 (HLR1) registers the information of the plurality of mobile terminals to the information of the mobile terminal 110 to be switched (S207).

Next, the customer information system transmits the IMSI and MSISDN mapping data of the mobile terminal 120 of the mobile communication subscriber who applied for the terminal switching service to the FNPS 180 (S209), and the FNPS 180 transmits the received IMSI and the received IMSI. The MSISDN mapping data is registered and managed (S211). In addition, the customer information system includes terminal switching subscription information, that is, information MS1 of the switching target mobile terminal 110 and information of mobile terminals of a plurality of subscribers MS2 # 1, MS2 # 2, MS2 # 3, and MS2 # 4. ...) To the terminal switching server 170 (S213), the terminal switching server 170 registers and manages the information based on the switching target mobile terminal 110 (S215).

3 is a flowchart illustrating a process of setting a terminal switching function in a terminal switching service system according to an embodiment of the present invention. The home location register 160 and the target of switching, which receive profile information of an existing mobile terminal 120, are shown in FIG. This is an example of the case where the home location registers 150 that receive profile information of the mobile terminal 110 are the same.

As shown in FIG. 3, first, the mobile subscriber may switch to the switching target mobile terminal 110 in order to switch the use of the terminal from the previously used mobile terminal 120 to the switching target mobile terminal 110 (MS1 in FIG. 3). Enter the terminal switching service activation code (eg, * 120) and the telephone number of the existing mobile terminal 120 (ie, MSISDN, denoted as 'MSISDN2' in FIG. 3). Then, the switching target mobile terminal 110 receives a service profile of the switching target mobile terminal 110 via the exchange 130 (MSC1 in FIG. 3) through a processUSSD (Unstructured Supplementary Service Data) -Request message, which is a terminal switching request message. Transmit to the home location register (HLR) (S301, S303). Here, the ProcessUSSD-Request message includes the IMSI (denoted as 'IMSI1' in FIG. 3), the service activation code, and the telephone number (MSISDN2) of the existing mobile terminal 120 of the switching target mobile terminal 110.

The home location register then analyzes the ProcessUSSD-Request message received via the exchange MSC1. Since the ProcessUSSD-Request message includes a terminal switching service activation code (* 120), the home location register transmits the ProcessUSSD-Request message to the terminal switching server 170 for terminal switching processing (S305).

Upon receiving the ProcessUSSD-Request message from the home location register, the terminal switching server 170 includes the IMSI of the mobile terminal 110 to be switched, the telephone number (ie, MSISDN) of the existing mobile terminal 120 and the existing mobile terminal 120. In step S307, an ATM (AnyTime Modification) message, which is a terminal switching command message including identification information indicating the terminal switching to the switching target mobile terminal 110, is transmitted to the FNPS 180. The FNPS 180 searches for the IMSI (denoted IMSI2 in FIG. 3) of the existing mobile terminal 120 using the phone number of the existing mobile terminal 120 included in the ATM message transmitted from the terminal switching server 170. Thereafter, the phone number of the existing mobile terminal 120 of the ATM message is changed to the searched IMSI and transmitted to the home location register (S309).

Next, the home location register, based on the identification information indicating the terminal switching included in the ATM message, the IMSI of the mobile terminal 110 to be switched, the telephone number (MSISDN) of the existing mobile terminal 120 and the service profile information. And a subscriber information switching command message (i.e., an ISD (Insert Subscriber Data) message) including a terminal switching activation identification code, is transmitted to an exchange 130 (MSC1) in which the switching target mobile terminal 110 is located (S311). Also, although not shown, the packet is transmitted to a packet switched node (SGSN) in which the switching target mobile terminal 110 is located. The switch 130 (MSC1) and the packet switching node where the switch target mobile terminal 110 is located include the telephone number (MSISDN) and the service of the switch target mobile terminal 110 mapped to the IMSI of the switch target mobile terminal 110. Substitute the profile information with the telephone number (MSISDN) and service profile information of the existing mobile terminal 120, set that the terminal switching service is activated, and transmits a response message to the home location register (S313).

In addition, the home location register, the subscriber information deactivation command message including the IMSI and the general call processing deactivation identification code of the existing mobile terminal 120, i. Subscriber Data) message) is transmitted to the switch 140 (MSC2) in which the existing mobile terminal 120 is located (S315), and also to a packet switched node (SGSN) although not shown. The switch 140 and the MSC2 in which the existing mobile terminal 120 is located and the packet switching node deactivate the general call processing of the existing mobile terminal 120 and transmit a response message to the home location register (S317).

In this way, the home location registers that have received the response messages from the exchanges MSC1 and MSC2 and the packet-switching node transmit the ATM response message to the terminal switching server 170 as a result of the processing (S319 and S321). The terminal switching server 170 manages that the terminal switching is set from the existing mobile terminal 120 to the switching target mobile terminal 110 and transmits a result notification message to the home location register (S323). The home location register transmits the processing result to the switching target mobile terminal 110 (S325). Accordingly, the home location register displays and manages that the terminal switching has been made to the switching target mobile terminal 110 with respect to the existing mobile terminal 120, and is also the switching target mobile terminal 110 as location registration information of the existing mobile terminal 120. The address information of the switch 130 (MSC1) and the packet switched node of the network) is set and managed (S327). Accordingly, the home location register proceeds to call processing using the exchange information of the switching target mobile terminal 110 instead of the exchange information of the existing mobile terminal 120 when an incoming location query is received from the exchange. . Here, when the switching target mobile terminal 110 is a telematics vehicle terminal, the home location register sets that the target of the terminal switching service is a vehicle. In addition, the home location register indicates and manages that the terminal switching is made from the existing mobile terminal 120 in the information of the switching target mobile terminal 110. The stored terminal switching information is used when the switching target mobile terminal 110 registers a location in the terminal switching state.

According to the above process, the profile information of the switching target mobile terminal 110 in the mobile communication network is replaced with the profile information of the existing mobile terminal 120, the profile information of the existing mobile terminal 120 is deactivated, All the incoming calls, such as voice call, video call, text message call, multimedia message call, packet call, etc., may be received by the switching target mobile terminal 110 instead. Therefore, when the mobile terminal 110 to be switched is a telematics terminal mounted in a vehicle, the mobile communication subscriber boards a vehicle, converts his mobile terminal into a telematics terminal, and calls calls to be received by the mobile terminal to the telematics terminal. It will be available instead. Accordingly, the mobile subscriber can use the mobile communication service without being disturbed while driving.

4 is a flowchart illustrating a process of setting terminal switching in a terminal switching service system according to another exemplary embodiment of the present invention, wherein a home location register and a switching target mobile terminal 110 accommodate profile information of an existing mobile terminal 120. ) Is an example of a case where the home location register for accommodating profile information is different.

As shown in FIG. 4, first, the mobile subscriber may switch to the switching target mobile terminal 110 in order to switch the use of the terminal from the previously used mobile terminal 120 to the switching target mobile terminal 110 (MS1 in FIG. 4). Enter the terminal switching service activation code (eg, * 120) and the telephone number of the existing mobile terminal 120 (ie, MSISDN, denoted as MSISDN2 in FIG. 4). Then, the switching target mobile terminal 110 receives a ProcessUSSD-Request message, which is a terminal switching request message, through a switch 130 (MSC1 in FIG. 4) and receives a service profile of the switching target mobile terminal 110. In FIG. 4, the data is transmitted to the HLR1 (S401 and S403). Here, the ProcessUSSD-Request message includes the IMSI (denoted as IMSI1 in FIG. 4), the service activation code, and the MSISDN of the existing mobile terminal 120 of the switching target mobile terminal 110.

Home location registerer 150 (HLR1) then analyzes the ProcessUSSD-Request message received via exchange 130 (MSC1). Since the ProcessUSSD-Request message includes a terminal switching service activation code, the home location register HLR1 transmits the ProcessUSSD-Request message to the terminal switching server 170 for terminal switching processing (S405).

The terminal switching server 170 that receives the ProcessUSSD-Request message from the home location register 150 (HLR1) is the IMSI of the switching target mobile terminal 110, the MSISDN of the existing mobile terminal 120, and the existing mobile terminal 120. The ATM message including the identification information indicating the switching of the terminal to the switching target mobile terminal 110 is transmitted to the FNPS 180 (S407). The FNPS 180 searches for IMSI (denoted IMSI2 in FIG. 4) of the existing mobile terminal 120 using the MSISDN of the existing mobile terminal 120 included in the ATM message transmitted from the terminal switching server 170. In operation S409, the telephone number of the existing mobile terminal 120 is changed to the searched IMSI in the ATM message and the home location register 150 (HLR1) is transmitted.

Next, the home location register 150 (HLR1) analyzes the ATM message and determines the terminal switching from the existing mobile terminal 120 to the switching target mobile terminal 110 and stores the profile information of the existing mobile terminal 120. Since it is not managed, the home location registers 160 (HLR2) for managing the profile information of the existing mobile terminal 120, the IMSI of the existing mobile terminal 120, the IMSI of the switching target mobile terminal 110, and the switching target mobile terminal The ATM message including the addresses of the switch 130 (MSC1) and the packet switching node (SGSN1) in which the 110 is located (S411) is transmitted.

Receiving such an ATM message, the home location registers 160 and HLR2 identify the IMSI of the switching target mobile terminal 110, the MSISDN of the existing mobile terminal 120, the service profile information of the existing mobile terminal 120, and the terminal switching activation identification. A subscriber information switching command message (i.e., an Insertion Subscriber Data (ISD) message) including a code is transmitted to an exchange 130 (MSC1) in which the switching target mobile terminal 110 is located (S413), and is not shown in the figure. Although not transmitted, it is also transmitted to the packet switching node in which the switching target mobile terminal 110 is located. The exchanges 130 and MSC1 and the packet-switching node where the switching target mobile terminal 110 is located have existing MSISDN and service profile information of the switching target mobile terminal 110 mapped to the IMSI of the switching target mobile terminal 110. Substitute the MSISDN and the service profile information of the mobile terminal 120, set the terminal switching service is activated, and transmits a response message to the home location register (160, HLR2) (S415).

In addition, the home location register (160, HLR2), the subscriber information deactivation command message including the IMSI and the general call processing deactivation identification code of the existing mobile terminal 120 to set the existing mobile terminal 120 in the deactivation mode (ie (Insert Subscriber Data (ISD) message) is transmitted to the switch 140 (MSC2) in which the existing mobile terminal 120 is located (S417), and is also transmitted to the packet switched node although not shown in the figure. The switch 140 (MSC2) and the packet switching node in which the existing mobile terminal 120 is located deactivate the general call processing of the existing mobile terminal 120 and transmit a response message to the home location register 160 (HLR2) ( S419).

As such, the home location registers 160 and HLR2 that have received the response message from the exchange 140 and the MSC2 and the packet switched node transmit the ATM response message to the home location register 150 and HLR1 as the processing result response (S421). The home location register 150 (HLR1) transmits an ATM response message to the terminal switching server 170 (S423 and S425). The terminal switching server 170 sets that the terminal switching has been made from the existing mobile terminal 120 to the switching target mobile terminal 110 and transmits a result notification message to the home location register 150 (HLR1) (S427). Accordingly, the home location register 150 (HLR1) transmits the result notification message to the switching target mobile terminal 110 via the switch 130 (MSC1) (S429).

According to the above process, the home location registers 160 and HLR2 accommodating the existing mobile terminal 120 set that the existing mobile terminal 120 has been switched to the mobile terminal 110 to be switched, and also the mobile terminal to be switched ( Set the information of the home location register that accommodates 110, and also set the information of the switch 130 (MSC1) and the packet-switched node that accepts the switching target mobile terminal 110 as the location registration information of the existing mobile terminal 120. (S433). Accordingly, when the home location register 160 receives a destination location query for the existing mobile terminal 120 from the switch 140 (MSC2), the switch information of the switching target mobile terminal 110 is not the exchange information of the existing mobile terminal 120. Proceed with call processing using. In addition, the home location register 150 (HLR1) displays and manages that the terminal switching has been made from the existing mobile terminal 120 in the information of the switching target mobile terminal 110 (S431). The stored terminal switching information is used when the switching target mobile terminal 110 registers a location in the terminal switching state.

As a result, the profile information of the existing mobile terminal 120 is replaced with the profile information of the switching target mobile terminal 110 in the mobile communication network, and the profile information of the existing mobile terminal 120 is deactivated and is received by the existing mobile terminal 120. All calls, for example, voice call calls, video call calls, text message calls, multimedia message calls, packet calls, and the like, can be transferred to the mobile terminal 110 to be switched. Therefore, when the mobile terminal 110 to be switched is a telematics terminal mounted in a vehicle, the mobile communication subscriber boards a vehicle, converts his mobile terminal into a telematics terminal, and calls calls to be received by the mobile terminal to the telematics terminal. It will be available instead. Accordingly, the mobile subscriber can use the mobile communication service without being disturbed while driving.

On the other hand, the embodiment with reference to Figures 3 and 4 is that one existing mobile terminal 120 to the terminal switching to the switching target mobile terminal 110, but the present invention is not limited thereto, as described with reference to FIG. As a plurality of mobile communication subscribers can designate the same switching target mobile terminal 110 to subscribe to the terminal switching service, a plurality of existing mobile terminals 120 can simultaneously switch terminals to the switching target mobile terminal 110. have. The user of the plurality of existing mobile terminals 120 sets the terminal switching to the switching target mobile terminal 110 according to the process described with reference to FIGS. 3 and 4, respectively. In this case, since the plurality of existing mobile terminals 120 simultaneously switch terminals to one switching target mobile terminal 110, the switching unit 130 (MSC1) and the packet switching node that accommodates the switching target mobile terminal 110 switch. The MSISDN and the service profile of the plurality of existing mobile terminals 110 are set in IMSI of the target mobile terminal 110.

FIG. 5 is a flowchart illustrating a process of releasing terminal switching in a terminal switching service system according to an embodiment of the present invention. The home location register and the switching target mobile terminal 110 accommodating profile information of the existing mobile terminal 120 are shown in FIG. ) Is an example of a case where the home location register that accepts the profile information is identical.

As shown in FIG. 5, first, the mobile subscriber deactivates the terminal switching service to the switching target mobile terminal 110 in order to release the terminal switching to the switching target mobile terminal 110 and use the existing mobile terminal 120 again. Enter a code (e.g., * 121) and enter a call button. Then, the switching target mobile terminal 110 transmits a ProcessUSSD-Request message, which is a terminal switching release request message including its IMSI (indicated by IMSI1 in FIG. 5) and an inactivation code, through the exchange 130 (MSC1). In step S501, S503, the service profile 110 receives the service profile of the home location register.

The home location register then analyzes the ProcessUSSD-Request message received via the exchange 130 (MSC1). Since the ProcessUSSD-Request message includes the terminal switching service deactivation code, the home location register searches for the MSISDN (denoted as MSISDN2 in FIG. 5) of the existing mobile terminal 120 for the terminal switching release processing, and the MSISDN and the switching target. The ProcessUSSD-Request message including the IMSI of the mobile terminal 110 and the service deactivation code is transmitted to the terminal switching server 180 (S505).

Upon receiving the ProcessUSSD-Request message from the home location register, the terminal switching server 180 is based on the service deactivation code included in the message, and the IMSI of the switching target mobile terminal 110, the MSISDN of the existing mobile terminal 120, and the like. The ATM message including the identification information indicating the terminal switching release from the existing mobile terminal 120 to the switching target mobile terminal 110 is transmitted to the FNPS 180 (S507). The FNPS 180 searches for the IMSI (denoted IMSI2 in FIG. 5) of the existing mobile terminal 120 using the MSISDN of the existing mobile terminal 120 included in the ATM message transmitted from the terminal switching server 170. In operation S509, the MSISDN of the existing mobile terminal 120 of the ATM message is changed to the searched IMSI and transmitted to the home location register.

Next, the home location register stores and manages the profile information of the existing mobile terminal 120 as well as the profile information of the mobile terminal 110 to be switched, and thus is based on the identification information indicating the terminal switching release included in the ATM message. The subscriber information switching release command message including the IMSI of the switching target mobile terminal 110, the MSISDN of the switching target mobile terminal 110, and the service profile information (ie, Delete Subscriber Data (DSD) / Insert Subscriber Data (ISD)). Message) is transmitted to the switch 130 (MSC1) in which the switching target mobile terminal 110 is located (S511), and is also transmitted to the packet switching node although not shown in the figure. The switch 130 (MSC1) and the packet switching node where the switching target mobile terminal 110 is located, reset the MSISDN and service profile information of the existing mobile terminal 120 mapped to the IMSI of the switching target mobile terminal 110. The MSSDN and the service profile information of the switching target mobile terminal 110 are restored, the terminal switching service is deactivated, and a response message is transmitted to the home location register (S513).

The home location register also includes a subscriber information activation command message (ie, Delete Subscriber Data (DSD) / Insert Subscriber) that includes the IMSI of the existing mobile terminal 120 in order to set the existing mobile terminal 120 to an activation mode. Data) message) is transmitted to the switch 140 (MSC2) and the packet switched node in which the existing mobile terminal 120 is located (S515). The switch 140 and the MSC2 in which the existing mobile terminal 120 is located and the packet switching node activate profile information of the existing mobile terminal 120 and transmit a response message to the home location register (S517).

In this way, the home location register which has received the response message from the switchboards MSC1 and MSC2 and the packet switched node transmits the ATM response message to the terminal switching server 170 as a processing result (S519, S521). The terminal switching server 170 sets that the terminal switching from the existing mobile terminal 120 to the switching target mobile terminal 110 is released and transmits a result notification message to the home location register (S523). The home location register transmits the processing result to the switching target mobile terminal 110 (S525). Accordingly, the home location register deletes all of the terminal switching setting information of the existing mobile terminal 120 and releases it (S527).

Transmit to the home location register (150, HLR1) that receives the service profile of (110) (S601, S603).

Home location registerer 150 (HLR1) then analyzes the ProcessUSSD-Request message received via exchange 130 (MSC1). Since the ProcessUSSD-Request message includes a terminal switching service deactivation code, the home location register 150 (HLR1) finds an MSISDN (denoted MSISDN2 in FIG. 6) of the existing mobile terminal 120 for terminal switching release processing. A ProcessUSSD-Request message including the MSISDN, the IMSI of the switching target mobile terminal 110 (indicated by IMSI1 in FIG. 6), and the service deactivation code is transmitted to the terminal switching server 170 (S605).

The terminal switching server 170 receiving the ProcessUSSD-Request message from the home location register HLR1 is based on the service deactivation code included in the message, and the IMSI of the switching target mobile terminal 110 and the existing mobile terminal 120. The ATM message including the telephone number (ie, MSISDN) and identification information indicating the release of the terminal switching from the existing mobile terminal 120 to the switching target mobile terminal 110 is transmitted to the FNPS 180 (S607). The FNPS 180 searches for the IMSI (denoted IMSI2 in FIG. 6) of the existing mobile terminal 120 by using the MSISDN of the existing mobile terminal 120 included in the ATM message transmitted from the terminal switching server 170. The MSISDN of the existing mobile terminal 120 of the ATM message is changed to the searched IMSI and transmitted to the home location register 150 (HLR1) (S609).

The switch 150 and the MSC1 in which the switch target mobile terminal 110 is located and the packet switching node reset the MSISDN and service profile information of the existing mobile terminal 120 mapped to the IMSI of the switch target mobile terminal 110. The MSSDN and service profile information of the switching target mobile terminal 110 are restored and the terminal switching service is deactivated, and a response message is transmitted to the home location register 150 (HLR1) (S621).

As such, the home location registers 150 and HLR1 that have received the response message from the exchange 130 and the MSC1 and the packet switched node transmit the ATM response message to the terminal switching server 180 as a processing result (S623 and S625). The terminal switching server 180 sets and manages that the terminal switching from the existing mobile terminal 120 to the switching target mobile terminal 110 is released and transmits a result notification message to the home location register 150 (HLR1) (S627). The home location registerer 150 (HLR1) transmits a result notification message to the switching target mobile terminal 110 to notify that the terminal switching is released (S629). Subsequently, the home location registers HLR1 and HLR2 delete all terminal switching information previously set and restore them to their original state (S631 and S633).
