The personal information is personal information of a user stored in a terminal used by the user. For example, the telephone number of another person, the content of an e-mail, a ring tone, a standby screen, and the like are given. The charging information indicates a fee charged to the user. The user information table may store information such as usage history and service contents in addition to the above.

FIG. 4 is a diagram showing an example of the terminal information table stored by the terminal information database 43. As shown in FIG. 4, the terminal information table stores a terminal ID, a use state, a last user name, and a last change time. The terminal information database 43 stores a terminal information table for each terminal registered in the mobile phone system according to the present embodiment. Here, the management server 4 registers the terminal before the user purchases the terminal, for example, when the terminal is shipped from a factory or sold at a store. In another embodiment, the terminal may be registered in the terminal information table using a terminal. Hereinafter, each information stored in the terminal information table will be described.

Terminal ID stored in terminal information table
Is information for identifying a terminal, and is the same as the terminal ID stored in the terminal information of the user information table. The usage status and the last change time are the same as the terminal ID, usage status, and last change time stored in the terminal information of the user information table. The final username is
The current or previous user name of the terminal. Therefore,
As shown in FIG. 3, the terminal ID stored in the terminal information of the user information table of the user name “taro-m” is “ABC-
12345 ″, as shown in FIG.
The final user name in the terminal information table of “ABC-12345” is “taro-m”. The terminal information table is used, for example, when the information processing unit 41 specifies a user from terminal information. As described above, the contents of the terminal information table are the same as a part of the contents of the user information table.

Next, the operation for changing the terminal used by the user will be described. As an example, in FIG.
However, a case where the terminal is changed from the terminal A11 to the terminal B12 will be described. In the present embodiment, the user X
Performs the change using the terminal B12 which is the terminal to be changed. First, the user name and password of the user X are input to the terminal B12. The input user name and password and the terminal ID of the terminal B12 are transmitted to the management server 4 via the base station 2 and the exchange 3. This allows
Processing in the data management unit 411 of the information processing unit 41 is started. Hereinafter, processing in the data management unit 411 when a user changes a terminal used will be described.

FIG. 5 is a flowchart showing the flow of processing in the data management unit 411 when changing the terminal used by the user. First, the data management unit 411 receives the user name and password of the user X transmitted from the terminal B12 (Step S101). Next, the data management unit 411 authenticates whether the user X is a legitimate user using the user name and password of the user X received from the terminal B12 (step S10).
2). In the authentication in step S102, the set of the user name and the password of the user X received from the terminal B12 is
The determination is made based on whether or not the user X matches the set of the user name and the password in the user recognition information of the user information table for the user X. If the authentication in step S102 fails, the data management unit 411 sends a message to the effect that the model change has failed to the terminal B12 (step S103), and ends the process. On the other hand, step S10
2 is successful, the data management unit 411
Performs the process of step S104.

If the authentication in step S102 is successful, the data management unit 411 determines whether the terminal to be changed is a registered terminal (step S104). The determination in step S104 is made based on whether or not the terminal information database 43 stores a terminal information table for the terminal to be changed, that is, the terminal B12.
If the terminal to be changed is not a registered terminal, the terminal to be changed is a terminal that cannot be used in the mobile phone system according to the present embodiment. Therefore, when the terminal of the change destination is not a registered terminal, the data management unit 411 performs the process of step S103 described above. On the other hand, if the terminal to be changed is a registered terminal, the data management unit 411 proceeds to step S1
05 is performed.

If the terminal to be changed is a registered terminal in step S104, data management unit 411 determines whether or not an old terminal exists (step S10).
5). Here, the old terminal refers to the terminal used by the user X immediately before. The determination in step S105 is based on the latest terminal ID in the user information table for user X.
Is performed depending on whether or not is stored. The absence of the old terminal means that the user X registers the terminal for the first time after the contract with the communication carrier.
When the old terminal does not exist, that is, when the latest terminal ID is not stored in the user information table for the user X, the data management unit 411 performs the process of step S109. Therefore, the process of step S105 is a process for avoiding the process of step S108 when the user X registers the terminal for the first time, because there is no need to restrict the use of the old terminal.

On the other hand, when the old terminal exists, that is,
The user information table for the user X includes the latest terminal I
If D is stored, the data management unit 411 determines whether the old terminal is the same as the terminal that transmitted the user name and the password, that is, the terminal B12 (step S106). The determination in step S106 is
This is performed by comparing the latest terminal ID stored in the user information table for the user X with the terminal ID of the terminal B12. When the old terminal and the terminal B12 are the same, there is no need to perform the use restriction process and the terminal registration process of the old terminal. Therefore, as a result of the comparison, if the latest terminal ID stored in the user information table for the user X is the same as the terminal ID of the terminal B12, the data management unit 4
11 transmits the personal information to the terminal B12 (step S107), and performs the process of step S110. On the other hand, when the latest terminal ID stored in the user information table for the user X is different from the terminal ID of the terminal B12, the data management unit 411 performs a use restriction process on the old terminal (step S108). This subroutine step S
Details of the process of 108 will be described later. Next, the data management unit 411 performs a registration process for the terminal B12 (Step S109). Details of the processing of this subroutine step S109 will be described later. Further, the data management unit 41
1 sends a message to the effect that the change of the terminal has been completed to the terminal B1.
2 (step S110), and the process ends.

FIG. 6 is a flowchart showing details of step S108 in FIG. First, the data management unit 411 confirms a response to the terminal A11, which is an old terminal, and determines whether or not there is a response (step S1081).
If there is no response from the terminal A11, the data management unit 411
Ends the processing. On the other hand, if there is a response from the terminal A11, the data management unit 411 sends a response to the terminal A11.
The terminal A11 requests transmission of the personal information stored (step S1082). On the other hand, the terminal A11 is
The personal information stored in 11 is transmitted to the management server 4. Next, the data management unit 411 sets the terminal A11
Is updated in the user information table for the user X using the personal information received from the user (step S1).
083). As a result, the latest personal information for the user X is stored in the user information table for the user X. Next, the data management unit 411 requests the terminal A11 to delete personal information (step S108).
4). In response to the processing in step S1084, the terminal A11
Deletes the personal information stored in the terminal A11. The process in step S1084 is a process for preventing a terminal not registered in the management server 4 as a terminal to be used from storing personal information, thereby preventing leakage of personal information. Further, the data management unit 411
The usage status of the old terminal is set to unusable (step S10).
85), end the processing. The process of step S1085 is performed by writing “unusable” in the usage status of the terminal information table for the terminal A11. With the processing of steps S1081 to S1085, the use restriction processing of the old terminal is completed.

FIG. 7 is a flowchart showing details of step S109 in FIG. First, the data management unit 411 transmits the personal information stored in the user information table for the user X to the terminal B12, which is the terminal after the change (step S1091). Further, the data management unit 411 updates the terminal information in the user information table for the user X and the last user name in the terminal information table for the terminal B12 (Step S109)
2). In step S1092, the update of the terminal information in the user information table for the user X is performed by writing the terminal ID of the terminal B12 as the latest terminal ID and writing the current time as the last change time in the user information table. In step S1092, the update of the last user name in the terminal information table for the terminal B12 is performed in step S101.
This is performed by setting the user name of the user X received from the user as the final user name. Next, the data management unit 411
For the user who has used the terminal B12 immediately before, the use status of the terminal is set to be unusable (step S109).
3), end the process. The processing in step S1093 is
In the usage status of the user information table for the user X,
This is performed by writing “unusable”. The terminal registration processing is completed by the processing in steps S1091 to S1093 described above.

In the present embodiment, the user
The terminal used was changed using the terminal B12 which is a terminal to be newly used. Here, as another form, the terminal to be used may be changed from a terminal other than the terminal newly used by the user, that is, a terminal other than the terminal B12. In this case, a terminal other than the terminal B12 needs to transmit the terminal ID of the terminal to be changed to the management server 4 in addition to the user name and the password.

The terminal used in the mobile phone system according to the present embodiment can change the use state of a desired terminal in addition to changing the terminal used as described above. As an example, a case where the user X changes the usage status of the terminal B12 using the terminal A11 will be described.
In this case, the terminal A11 is a terminal that changes the user name and password of the user X, and the usage status, that is, the terminal B
The terminal ID of the terminal 12 is transmitted to the management server 4 via the base station 2 and the exchange 3. Further, the terminal A11
Transmits a change request, that is, a request to disable or enable use, to the management server 4. Hereinafter, a process performed by the data management unit 411 when the usage status of the terminal B12 is changed using the terminal A11 will be described.

FIG. 8 is a diagram showing how to change the usage status of the terminal.
9 is a flowchart illustrating a flow of processing in a data management unit 411. First, the data management unit 411 checks the terminal A1
It receives the user name and password of the user X, the terminal ID of the terminal whose use status is to be changed, and the change request transmitted from Step 1 (step S201). Next, the data management unit 411 authenticates whether the user is an authorized user using the user name and password of the user X received from the terminal A11 (step S202). In the authentication in step S202, the set of the user name and the password of the user X received from the terminal A11 is
Is determined based on whether or not the combination of the user name and the password in the user recognition information of the user information table for the user is matched. When the authentication in step S202 has failed, the data management unit 411 transmits a message indicating that the authentication has failed to the terminal A11 (step S20).
3), end the process. On the other hand, when the authentication in step S202 is successful, the data management unit 411 performs the process in step S204.

If the authentication in step S202 is successful, the data management unit 411 determines whether the user and the terminal whose usage status is to be changed correspond (step S202).
204). The determination in step S204 is the user X
Terminal I stored in the user information table for
This is performed based on whether D and the terminal ID received from the terminal A11 are the same. If the user and the terminal whose usage status is changed do not correspond to each other, that is, if the latest terminal ID stored in the user information table for the user X is different from the terminal ID received from the terminal A11, the data management unit 411 Then, the process of step S203 is performed, and the process ends. This can prevent the user from changing the usage status of the terminal used by another user. On the other hand, when the user and the terminal whose usage status is changed correspond to each other, that is, when the latest terminal ID stored in the user information table for the user X is the same as the terminal ID received from the terminal A11, Management unit 4
11 judges whether or not the change request received from the terminal A11 is a usable request (step S205).

In step S205, if the change request received from terminal A11 is not an enable request, that is, if it is an disable request, data management unit 411
The usage status is set to unusable (step S206).
Specifically, the data management unit 411 sets the use status of the user information table for the user X and the use status of the terminal information table for the terminal B12 to unusable. Further, the data management unit 411 requests the terminal whose use status is set to be unusable to delete personal information (step S207), and performs the process of step S210. The process of step S207 is a process for preventing a terminal that is not registered in the management server 4 as a terminal to be used from storing personal information, thereby preventing leakage of personal information.

On the other hand, in step S205, the terminal A
If the change request received from 11 is an enable request,
The data management unit 411 sets the use status to be usable (step S208). Specifically, the data management unit 41
1 sets the use status of the user information table for the user X and the use status of the terminal information table for the terminal B12 to be usable. Further, the data management unit 411 transmits the personal information stored in the user information table for the user X to the terminal B12 (Step S20)
9). The processing in step S209 takes into account that the personal information of the terminal previously set to be unusable has been deleted by the processing in step S207. Finally, the data management unit 411 transmits a message to the effect that the change of the usage status of the terminal has been completed to the terminal A11 (step S210), and ends the process.

As described above, the management server 4 requests that the personal information stored in the terminal be deleted when the terminal used by the user is changed and when the usage status of the terminal is changed. In addition, the management server 4 checks the usage status of the terminal when the power of the disabled terminal is turned on. If the usage is disabled, the management server 4 requests the deletion of the personal information. Send This is a process for preventing the leakage of personal information even in this case, since the personal information cannot be deleted if the power of the terminal is turned off when requesting the deletion of personal information.

Next, an operation of the terminal A11 used in the mobile phone system according to the present embodiment when transmitting personal information stored in the terminal A11 will be described. The terminal A11 transmits the personal information to the management server 4 when the transmission of the personal information is requested from the management server 4 in the process of step S1082 in FIG. Terminal A11
In addition to this case, the personal information is automatically transmitted to the management server 4 when the power is turned off, when the battery is almost exhausted, when the user is going out of the service area, or the like. Hereinafter, the configuration of the terminal A11 will be described.

FIG. 9 is a block diagram showing the configuration of terminal A11 used in the mobile phone system according to the present embodiment. In FIG. 9, a terminal A11 includes a transmitting / receiving unit 11
1, the transmission determination unit 112, the storage unit 113, and the input unit 1
14 is provided. The transmission / reception unit 111 performs wireless communication with the base station 2. The transmission determination unit 112
A determination is made as to whether or not to transmit the personal information stored in 3. The transmission determination unit 112 determines whether to transmit the personal information stored in the storage unit 113 by transmitting the personal information to the terminal by the data management unit 411 of the management server 4 in step S1082 in FIG. Whether a request has been made, whether a personal information transmission command has been input from the input unit 114, whether the terminal has been turned off, whether the power is about to run out, or whether the terminal has gone out of the service area. It is performed depending on whether or not. The storage unit 113 stores personal information about a user who is a user of the terminal, that is, a telephone number of another person, e-mail contents, a ringtone, a standby screen, and the like. The input unit 114 receives an instruction to transmit personal information. In addition, the input unit 114
It is used when the user inputs the telephone number of the partner user when making a call, or when the user inputs a user name, a password or the like when changing the terminal to be used.

As described above, the terminal A11 is connected to the storage unit 11
A determination is made as to whether or not to transmit the personal information stored in 3 and personal information is transmitted based on the result of the determination. Here, in another embodiment, the terminal, at regular intervals,
Personal information may be automatically transmitted to the management server. Further, the terminal may transmit the personal information only when the management server requests transmission of the personal information.

Next, the operation of the portable telephone system according to the present embodiment when connecting a telephone line will be described. Hereinafter, a case where the user X calls the user Y will be described. The terminal used by the user X is referred to as a terminal A11, and the terminal used by the user Y is referred to as a terminal B12. When user X calls user Y,
The telephone number of the user Y and the terminal ID of the terminal A11 are transmitted from the terminal A11 to the exchange 3 via the base station 2.
The exchange 3 having received the telephone number of the user Y and the terminal ID of the terminal A11 from the terminal A11 transmits the telephone number of the user Y and the terminal ID of the terminal A11 to the management server 4 in order to identify the terminal used by the user Y. Send. From the exchange 3, the telephone number of the user Y and the terminal ID of the terminal A11
Is received, the connection management unit 41 of the management server 4
2 is started. Hereinafter, processing in the connection management unit 412 when connecting a telephone line will be described.

FIG. 10 is a flowchart showing the flow of processing in connection management section 412 when connecting a telephone line. First, the connection management unit 412 determines whether the terminal A11 is a usable terminal (step S30).
1). The determination in step S301 is that the usage status of the terminal information table for the terminal A11 is “usable”.
Or "unusable". If the terminal A11 is not a usable terminal, that is, if the use status of the terminal information table for the terminal A11 is “unavailable”, the connection management unit 412 notifies the terminal A11 that the terminal cannot be used. (Step S302), the process ends. On the other hand, step S3
01, if the terminal A11 is a usable terminal, that is, if the use status of the terminal information table for the terminal A11 is “usable”, the connection management unit 41
2 performs the process of step S303.

In step S301, if terminal A11 is a usable terminal, it is determined whether or not there is a communication partner, that is, user Y (step S30).
3). The determination in step S303 is made based on whether the user information database 42 holds a user information table that stores the telephone number of the user Y.
Here, the fact that the user information database 42 does not hold the user information table that stores the telephone number of the user Y means that the telephone number of the user Y is not used, that is, a wrong telephone call. Therefore, when the user Y does not exist, that is, when the user information database 42 does not hold a user information table storing the telephone number of the user Y, the connection management unit 412
The terminal A11 is notified that the call is incorrect (step S304), and the process ends. On the other hand, when the user Y exists, that is, when the user information database 42
Holds a user information table storing the telephone number of the user Y, the connection management unit 412 proceeds to step S
305 is performed.

If user Y exists in step S303, connection management section 412 determines whether or not a terminal used by user Y exists (step S30).
5). The determination in step S305 is made based on whether or not the user information table for the user Y stores the latest terminal ID. The fact that the user information table for the user Y does not store the latest terminal ID means that the user Y has newly joined and has not used the terminal yet. Therefore, when there is no terminal used by the user Y, that is, when the user information table for the user Y does not store the latest terminal ID, the connection management unit 412 sends the terminal to the terminal A11. Notify that it has not been used yet (step S
306), and the process ends. On the other hand, when there is a terminal used by user Y, that is, when the user information table for user Y stores the latest terminal ID,
The connection management unit 412 performs the process of step S307.

In step S305, if there is a terminal used by user Y, connection manager 412 determines whether the terminal used by user Y is available (step S307). The determination in step S307 is made by referring to whether the usage status stored in the user information table for the user Y is “usable” or “unavailable”.

In step S307, if the terminal used by user Y is unusable, that is, user Y
If the use status stored in the user information table for "is unavailable", the connection management unit 412 causes the exchange 3 to connect the line to the answering service center 5 (step S308). Also, at the time of step S308, the connection management unit 412 causes the exchange 3 to connect the line to the answering machine center 5, and
Send the message number. On the other hand, the answering service center 5 stores the received message number and the message left by the user X in association with each other. Next, the connection management unit 412 stores the message number transmitted to the answering service center 5 and the user name of the user to be charged in the user information table for the user Y (step S309), and ends the processing. Hereinafter, step S309
Will be described in detail.

The connection management unit 412 detects the terminal ID of the terminal used by the user Y immediately before, that is, the latest terminal ID by referring to the user information table for the user Y. Next, the connection management unit 412 specifies the user name of the user currently using the detected terminal, that is, the final user name, by referring to the terminal information table for the detected terminal. Step S3
The processing in 09 is performed by associating the user name specified as described above with the message number transmitted to the answering service center 5 in step S308, and storing the same in the user information table for the user Y.

As described above, in step S309, the user to be charged is the user who is currently using the terminal used by user Y immediately before. In the process of step S307, when it is determined that the terminal used by the user Y is unusable, the user Y is lending the terminal to another user, or the user Y
May restrict the use of the terminal. Accordingly, the process of step S309 is to set the tuition of the answering machine message of the call received by the user Y while the user Y lends the terminal to the other user to the other user borrowing the terminal. This is a process for charging. In addition,
If user Y restricts the use of the terminal, step S
The user to be charged by the process of 309 is the user Y.

On the other hand, in step S307, if the terminal used by user Y is available, that is, if the use status stored in the user information table for user Y is “usable”, the connection management unit 412
Transmits the terminal ID of the terminal used by the user Y to the exchange 3 (step S310). Specifically, the connection management unit 412 transmits the latest terminal ID stored in the user information table for the user Y to the exchange 3. On the other hand, the exchange 3 is connected to the connection management unit 412 of the management server 4.
Connect the line to the terminal ID received from. If there is no response from the terminal connected to the line for a certain period of time, the exchange 3 notifies the management server 4 that there is no response. here,
The connection management unit 412 determines whether there is a response from the terminal used by the user Y (step S311). The determination in step S311 is made based on whether or not the exchange 3 has notified that there is no response. If there is a response from the terminal used by user Y, connection management section 412 ends the process. On the other hand, when there is no response from the terminal used by the user Y, the connection management unit 412 causes the exchange 3 to connect the line to the answering service center 5 (step S31).
2).

After step S312, connection management section 412
Causes the exchange 3 to connect the line to the answering service center 5 and transmits the message number to the answering service center 5. Further, the connection management unit 412 stores the message number transmitted to the answering service center 5 and the user name of the user Y in the user information table (step S3).
13), end the process. In step S313, the user to be charged is the user who listens to the message, that is, the user Y. This corresponds to step S31
In the process 3, since the user Y does not lend a terminal to another user as in the process of the step S 309, the user Y who listens to the message is charged a fee for listening to the message. is there.

Next, the operation of the mobile phone system according to the present embodiment will be described with respect to a billing process when a user listens to a message of an answering machine. As an example, a case in which user X uses terminal A11 to listen to an answering machine message will be described. When the user X calls the answering service center 5 to listen to the message, the terminal A11
Answering machine center 5 from exchange 3 through management server 4
Connected to. After the connection, the answering machine center 5 establishes the terminal A
The terminal ID of No. 11 and the message number of the message heard by the user X are transmitted to the management server 4. Thereby, the accounting process for the message listening fee in the data management unit 411 of the management server 4 is started. Hereinafter, a charging process in the data management unit 411 when charging a listening fee for an answering machine message will be described.

FIG. 11 is a flowchart showing the flow of a charging process in the data management unit 411 when charging a listening fee for an answering machine. First, the data management unit 411
Receives the terminal ID of the terminal that called from the answering service center 5, ie, the terminal A11, and the message number of the message heard by the user X (step S40).
1). Next, the data management unit 411 uses the terminal information table of the user information database 42 to specify the user who made the call, that is, the user X who is the user of the terminal A11 (step S402). Specifically, the data management unit 411 specifies the user X who is the terminal user from the last user name stored in the terminal information table for the terminal A11.

After step S402, the data management unit 41
1 charges a fee for listening to the message (step S40)
3). Specifically, the data management unit 411 specifies a user name stored in correspondence with the message number received in the process of step S401 by referring to the user information table for the user X. The user having the specified user name is the user to be charged. Here, the user to be charged is the user Z. Then, the data management unit 411 stores the specified user Z
Is written in the billing information stored in the user information table for.

After step S403, the data management unit 41
1 judges whether the user to be charged is the user who heard the message, that is, the user X (step S404). The determination in step S404 is made based on whether the user Z and the user X specified in the process in step S403 are the same. That is, the data management unit 411 determines in step S4
If the user Z and the user X specified in the process of 03 are the same, it is determined that the user to be charged is the user X himself. On the other hand, when the user Z specified in the process of step S403 is different from the user name of the user X, the data management unit 411 determines that the user to be charged is not the user X.

If it is determined in step S404 that the user to be charged is the user X,
The data management unit 411 ends the processing. On the other hand, when it is determined that the user to be charged is not the user X, the data management unit 411 determines that the user to be charged, that is, the user X
(Step S405), and the process ends. The processing in step S405 is performed by changing the user name of the message information stored in the user information table for user X to the user name of user X. Note that the process of step S405 is a process for charging the person who listens to the message when the message is heard from the second time.

In this embodiment, when a message is left while a user lends a terminal to another user, a fee for listening to the message is charged to the user who borrowed the terminal. As another embodiment, when the terminal is changed, the user may be able to select a charging target for the message audition fee.

Further, in this embodiment, one management server has a user information database and a terminal information database, but a plurality of management servers also share one user information database and a terminal information database. It may be in a form. In this case, information of users who contract with different communication carriers is shared by a plurality of communication carriers.

In the above description, the mobile phone system has been described as an example. However, the present invention can be applied to other communication systems in addition to the mobile phone system. For example, in a music data distribution system including a music data distribution terminal, the music data distribution server may hold a user ID and a terminal ID in association with each other. Further, a system is also conceivable in which a car navigation device having a network connection function can be used for payment of a fee, communication with another terminal, and the like. In this case, the server includes a car navigation device that is a terminal,
It must be registered in association with the user who is the user. Even in such a system, it is possible to change the registration of the user corresponding to the car navigation device using the car navigation device.
