The card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted into the card interface 13 by any known method. When determining that the subscriber information card 14 is inserted into the card interface 13, the card insertion determination unit 15 sets “1” in the card insertion flag stored in the temporary memory 19. On the other hand, when determining that the subscriber information card 14 is inserted into the card interface 13, the card insertion determining unit 15 sets “0” in the card insertion flag.

(Public network communication unit 16)
The public network communication unit 16 communicates with the outside through a public line network. In the communication terminal device 1, when the subscriber information card 14 is input to the card interface 13, the public network communication unit 16 communicates with other communication terminal devices 1 through the public line network. Thereby, the user can use the communication terminal device 1 to make a call with another user, for example.

(Local communication unit 17)
The local communication unit 17 communicates directly with another communication terminal device 1 without going through the public line network. The local communication unit 17 follows a communication method used in a conventional parent-child device system. Alternatively, short-range wireless communication standards such as Bluetooth (registered trademark) standards may be used. The local communication unit 17 is a local provided in the other communication terminal device 1 only when the communication terminal device 1 is locally (directly) connected to the other communication terminal device 1 by the local connection unit 18. Data communication is performed with the communication unit 17. Therefore, the local connection unit 18 does not perform communication through the public line network.

  As will be described later, when the communication terminal device 1 operates as a parent device, the local communication unit 17 in the parent device relays that a child device connected to the parent device communicates with the outside through the public line network. On the other hand, when the communication terminal device 1 operates as a slave unit, the local communication unit 17 in the slave unit communicates with the outside through the public line network via the master unit.

(Local connection unit 18)
The local connection unit 18 directly connects the communication terminal device 1 to another communication terminal device 1 without going through the public line network. The local connection unit 18 connects one communication terminal device 1 as a parent device and the other communication terminal device 1 as a child device. After this connection is established, the two communication terminal devices 1 can directly communicate with each other, for example, exchange data by the local communication unit 17. As will be described in detail later, when the subscriber information card 14 is inserted in the card interface 13 of the communication terminal device 1, the local connection unit 18 uses the communication terminal device 1 as a slave unit and the subscriber information card 14 uses the card interface. 13 is connected locally to the communication terminal device 1 as a base unit inserted in the network.

(Temporary memory 19)
The temporary memory 19 is a memory for temporarily storing various data processed, created, and output in the communication terminal device 1. In this temporary memory 19, for example, a card insertion flag indicating whether or not the subscriber information card 14 is inserted into the card interface 13 is stored. The temporary memory 19 is a volatile memory such as a RAM (Random Access Memory).

(Non-volatile memory)
Although not particularly illustrated, the input / output control unit 12, the card insertion determination unit 15, the public network communication unit 16, the local communication unit 17, and the local connection unit 18 described above are used as so-called program codes in the communication terminal device 1. It is stored in advance in a predetermined recording medium. Such a recording medium is, for example, a non-volatile memory such as a ROM (Read Only Memory) or a flash memory (registered commercial law).

(Parent-child connection flow)
An example in which two communication terminal devices 1 are locally connected to each other using one as a parent device and the other as a child device will be described below with reference to FIG. FIG. 2 shows a case where the communication terminal device 1 in which the subscriber information card 14 is not inserted into the card interface 13 is connected as a slave unit to the communication terminal device 1 in which the subscriber information card 14 is inserted into the card interface 13. It is a flowchart which shows an example of the flow of a process of. In this embodiment, the communication terminal device 1 that operates as a parent device when the subscriber information card 14 is inserted into the card interface 13, and the communication terminal device 1 that operates as a child device without a card inserted, Both have the configuration shown in FIG.

(Determination of insertion of subscriber information card 14)
As shown in FIG. 2, the card insertion determining unit 15 first checks the state of the card interface 13 (step S21). Thereby, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted into the card interface 13 (step S22). Here, when the card insertion determination unit 15 determines that the subscriber information card 14 is inserted in the card interface 13 (Yes), the communication terminal device 1 cannot operate as a slave unit. That is, since it cannot connect to the communication terminal device 1 as the parent device, the processing shown in FIG.

(Search for another communication terminal device 1)
When the card insertion determination unit 15 determines that the subscriber information card 14 is not inserted into the card interface 13, the local connection unit 18 is connected to another communication terminal device 1 that can be locally connected via the local communication unit 17. It is determined whether or not it exists in the vicinity of the communication terminal device 1 (step S23). Here, another communication terminal device 1 that can be connected through the local communication unit 17 is a state in which the subscriber information card 14 is inserted into the card interface 13 and can be connected to the public network via the public network communication unit 16. Means the communication terminal device 1 in FIG. That is, the communication terminal device 1 can operate as a parent device.

(Tentative connection)
When the local communication unit 17 performs data communication in accordance with the Bluetooth standard, the local connection unit 18 determines whether or not the communication terminal device 1 that can be locally connected exists by a general communication standard communication connection procedure. (Step S24). Here, when it is determined that there is another communication terminal device 1 that can be locally connected nearby, the local connection unit 18 temporarily makes a temporary connection to the communication terminal device 1 (step S25). The “temporary connection” here means a connection at a preparatory stage for the main connection after performing the communication connection for the first time and mutually authenticating the devices. During the temporary connection, the two communication terminal apparatuses 1 can perform data communication necessary for performing the main connection, but cannot perform other general data communication.

(Checking the master unit)
Next, the local connection unit 18 checks whether or not the temporary connection destination communication terminal device 1 is operating as a parent device. Specifically, it is confirmed through the local communication unit 17 whether or not the subscriber information card 14 is inserted into the card interface 13 in the temporary connection destination communication terminal device 1 (step S26). At this time, the local connection unit 18 in the temporary connection source communication terminal device 1 sends a signal for inquiring about the insertion state of the subscriber information card 14 to the local communication unit 17 of the connection destination communication terminal device 1 through the local communication unit 17. Send. In the communication terminal device 1 that has received this signal, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted in the card interface 13. In response to the determination result, the temporary communication destination local communication unit 17 creates a response signal indicating whether or not the subscriber information card 14 is inserted, and returns the response signal to the temporary connection source local communication unit 17. Thereby, in the temporary connection source communication terminal device 1, the local connection unit 18 joins the card interface 13 in the temporary connection destination communication terminal device 1 by confirming the content of the response signal received by the local communication unit 17. It is determined whether or not the person information card 14 is inserted (step S27).

(This connection)
When determining that the subscriber information card 14 is inserted in the temporary connection destination communication terminal device 1 (Yes), the local connection unit 18 connects the communication terminal device 1 to the temporary connection destination communication terminal device 1. (Step S29). That is, the temporary connection destination communication terminal device 1 is recognized as a parent device, and the temporary connection source communication terminal device 1 is set to operate as a child device. On the other hand, when it is determined in step S27 that the subscriber information card 14 has not been inserted into the temporary connection destination communication terminal device 1 (No), the communication terminal device 1 cannot operate as a parent device. Therefore, the local connection unit 18 in the temporary connection source communication terminal device 1 does not make a main connection to the temporary connection destination communication terminal device 1. Therefore, the process from step S24 to step S27 is repeated for another communication terminal apparatus 1 existing in the vicinity for a predetermined time set in advance (step S28).

  On the other hand, when it is determined in step S24 that there is no other communication terminal device 1 that can be locally connected (NO), the local connection unit 18 is within the communication range of the communication terminal device 1 that can be permanently connected as a parent device. It is determined that it does not exist. Thereby, the communication terminal device 1 complete | finishes the process shown in FIG.

(Information on this connection)
After the main connection is completed, the local connection unit 18 stores in the temporary memory 19 information indicating that both the parent device and the child device are currently in the main connection state. The temporary memory 19 stores this information until this connection is released. That is, in the communication terminal device 1 (communication terminal device 1 in which the subscriber information card 14 is inserted) that operates as a parent device, the local connection unit 18 stores information related to the currently connected child device in the temporary memory 19. To do. On the other hand, in the communication terminal device 1 (communication terminal device 1 in which the subscriber information card 14 is not inserted) operating as a slave unit, the local connection unit 18 stores information related to the main unit connected in the temporary memory 19. .

  The parent device or the child device may be provided with a predetermined interface that instructs to release the connection state at an arbitrary timing. Alternatively, this connection may be automatically released when the power of the parent device or the child device is turned off.

(Operation after this connection)
The operation of the communication terminal device 1 as a parent device and a child device after the main connection is performed may be a general operation of the parent device and the child device. In other words, the master unit may relay communication from the outside through the public network communication unit 16 to the slave unit. For example, when an incoming call is received from the outside via the public network communication unit 16 in the master unit, the master unit notifies the user of the incoming call, and the local communication unit 17 notifies the slave unit that the call has been received. To do. In the slave unit, when the user answers the incoming call, the local communication unit 17 transmits and receives data such as a call sound between the master and the slave unit.

(Function and effect)
As described above, the communication terminal device 1 is a communication terminal device 1 that can communicate through the public network when the subscriber information card 14 is inserted, and the subscriber information card 14 is connected to the communication terminal device 1 (card interface). 13) When the card insertion determination unit 15 that determines whether or not the card has been inserted and the card insertion determination unit 15 determine that the subscriber information card 14 has not been inserted into the communication terminal device 1, the subscriber information A local communication unit 17 is provided which communicates directly with the communication terminal device 1 serving as a master unit in a state where the card 14 is inserted and can communicate via the public line network, not via the public line network.

  The communication terminal device 1 can indirectly perform communication through the public line network even when the subscriber information card 14 is not inserted. That is, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted in the communication terminal device 1. At this time, when the card insertion determining unit 15 determines that the subscriber information card 14 is not inserted into the communication terminal device 1, the local communication unit 17 includes the communication terminal device 1 operating as a master unit, the public line Communicate directly without going through the network.

  When the local communication unit 17 executes the direct communication with the parent device, the communication terminal device 1 can be used as a child device of the parent device through the parent device, even if no subscriber information card 14 is inserted. Communication with the outside via the line network can be executed. In addition, the communication terminal device 1 as a parent device can cause the child device to indirectly execute communication with the outside via the public line network by the local communication unit 17 performing direct communication with the child device. become able to.

  Therefore, the user can use one communication terminal apparatus 1 as a master unit in some cases and as a slave unit in other cases. Thereby, the user can use a plurality of communication terminal devices 1 effectively.

  In addition, as a result of a general usage mode of the communication terminal device 1 corresponding to the subscriber information card 14, the user replaces the communication terminal device 1 as appropriate. As a result, the user naturally has a plurality of communication terminal devices 1. For this reason, unlike the conventional parent-child device system, the user does not need to purchase additional child devices. The communication terminal device 1 used as a slave is already highly functional. Therefore, there is no need for extra costs associated with the enhancement of the functions of the slave unit.

[Embodiment 2]
A second embodiment according to the present invention will be described below with reference to FIGS. 3 and 4 (communication terminal apparatus 30).
FIG. 3 is a block diagram showing a main configuration of the communication terminal apparatus 30 according to the second embodiment of the present invention. As shown in FIG. 3, the communication terminal device 30 of the present embodiment is configured to further include a subscriber information storage unit 31 and a connection determination unit 32 in addition to the communication terminal device 1 shown in FIG. 1.

(Subscriber information storage unit 31)
The subscriber information storage unit 31 records predetermined card specifying information stored in the subscriber information card 14. This card information is information for uniquely identifying the subscriber information card 14, and is information relating to the card serial number, for example.

(Connection determination unit 32)
The connection determination part 32 collates the card | curd specific information memorize | stored in the two communication terminal devices 30 which are going to perform parent-child connection. Specifically, the connection determination unit 32 operates as a slave unit, and operates as a master unit and card specifying information stored in the subscriber information storage unit 31 of the communication terminal device 30 that requests the main connection to the master unit. Then, it compares the card specifying information stored in the subscriber information storage unit 31 of the communication terminal device 30 that receives the main connection request from the slave unit. When it is determined that the card specifying information is substantially the same, the connection determination unit 32 determines that the two communication terminal devices 30 can be permanently connected to each other.

(Card specific information storage process)
The communication terminal device 30 reads the specific information stored in the subscriber information card and stores it in the subscriber information storage unit 31 at a predetermined timing. The processing at this time will be described below with reference to FIG. FIG. 4A is a flowchart illustrating an example of a processing flow when the communication terminal device 1 stores card specifying information in the subscriber information storage unit 31. First, when the user starts up the communication terminal device 1, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted in the card interface 13 (step S41). When determining that the subscriber information card 14 is inserted, the input / output control unit 12 reads out card specifying information for uniquely specifying the subscriber information card 14 from the subscriber information card 14 (step S42). The input / output control unit 12 stores the read card identification information in the subscriber information storage unit 31 (step S43).
(Connection determination processing)
Next, the connection determination process executed by the connection determination unit 32 based on the subscriber information stored in the subscriber information storage unit 31 will be described below with reference to FIG. FIG. 4B is a flowchart illustrating an example of the flow of the main connection determination process performed by the connection determination unit 32 when the local connection unit 18 performs the main connection of the communication terminal device 30.

(Send card specific information)
First, the local connection unit 18 starts a connection procedure for the communication terminal device 30 (step S51). As a result, the two communication terminal devices 30 are fully connected. When the connection procedure is started, in the communication terminal device 1 as a slave unit, the local connection unit 18 reads out the card specifying information stored in the subscriber information storage unit 31 and communicates through the local communication unit 17 as the master unit. It transmits to the terminal device 30. In the communication terminal device 1 that is the parent device, the local connection unit 18 receives the card specifying information transmitted from the communication terminal device 30 that is the child device, and stores it in the temporary memory 19.

(Reading card specific information)
In the communication terminal device 30 that is the parent device, the connection determination unit 32 reads the card specifying information of the subscriber information card 14 from the subscriber information card 14 inserted in the card interface 13 (step S52).

(Compare card specific information)
Next, the connection determination unit 32 compares the card specifying information acquired from the connection destination communication terminal device 30 with the card specifying information acquired from the subscriber information card 14. Thereby, the two communication terminal devices 30 determine whether the main connection is possible (step S53). Specifically, when it is determined that the two card specifying information is substantially the same, the connection determination unit 32 determines that the two communication terminal devices 30 can be permanently connected. When this determination is made, the local connection unit 18 establishes a connection by continuing this connection (step S54). On the other hand, when it is determined that the two card specifying information is not substantially the same, the connection determination unit 32 determines that the two communication terminal devices 30 should not be permanently connected. When this determination is made, the local connection unit 18 stops the main connection (step S55).

(Function and effect)
As described above, the connection determination unit 32 matches the subscriber information stored in the subscriber information card 14 inserted in the base unit with the subscriber information set in advance in the communication terminal device 30. It is determined whether or not. The subscriber information here is information relating to the user who purchased the subscriber information card 14. When the subscriber information matches, it means that the same user possesses the two communication terminal devices 30. Therefore, when it is determined that the subscriber information of the parent device matches the subscriber information of the child device, the local communication unit 17 establishes a communication connection between the child device and the parent device.

  Thereby, the communication terminal device 30 can prevent connecting with the main | base station which an irrelevant user has. Moreover, the communication terminal device 30 can prevent cost substitution. That is, the communication terminal device 30 (parent device) in which the subscriber information card 14 is inserted is unaware of the communication terminal device 30 (slave device) of another person in red who has no subscriber information card inserted. There is no connection. Therefore, it is possible to prevent another person's child machine from executing communication through the public line network through its own parent machine.

[Embodiment 3]
A third embodiment according to the present invention will be described below with reference to FIG.

(Communication terminal device 50)
FIG. 5 is a block diagram showing a main configuration of the communication terminal device 50 according to the third embodiment of the present invention. As illustrated in FIG. 5, the communication terminal device 50 according to the present embodiment further includes a parent / child determination unit 51, a communication impossibility warning unit 52, and a communication possible notification unit 53 in addition to the communication terminal device 1 illustrated in FIG. 1. It is.

(Parent-child determination unit 51)
The parent / child determination unit 51 determines whether the communication terminal device 50 is operating as a parent device or a child device. Specifically, the determination is made based on whether or not the subscriber information card 14 is inserted into the card interface 13. That is, when the subscriber information card 14 is inserted into the card interface 13, the communication terminal device 50 is determined to be a parent device. On the other hand, when it is determined that the subscriber information card 14 is not inserted into the card interface 13, the communication terminal device 50 is determined to be a slave unit. At this time, the parent-child determination unit 51 determines whether or not the subscriber information card 14 is inserted into the card interface 13 based on the value of the card insertion flag stored in the temporary memory 19, for example.

(Communication disabled warning unit 52)
When the communication terminal device 50 cannot communicate with the parent device, the communication impossibility warning unit 52 notifies the user to that effect. At this time, the communication disabled warning unit 52 notifies the user, for example, by displaying a predetermined message such as “cannot communicate with the parent device” on the screen of the communication terminal device 50.

  In the communication terminal device 50, information indicating what kind of warning is given to the user when the communication terminal device 50 is a child device and cannot communicate with the parent device is stored in the temporary memory 19 in advance. Further, information indicating what kind of warning is given to the user when the communication terminal device 50 is a parent device and cannot communicate with the child device is also stored in the temporary memory 19 in advance. The communication disabling warning unit 52 reads information related to the warning from the temporary memory 19 depending on whether the communication terminal device 50 is operating as a parent device or a child device, and issues a warning according to the information to the user. .

(Communication available notification unit 53)
The communicable notification unit 53 notifies the user that the parent device and the communication terminal device 50 can communicate with each other. At this time, the communicable notification unit 53 displays a predetermined message such as “I can communicate with the parent device” on the screen of the communication terminal device 50, for example.

  In the communication terminal device 50, the temporary memory 19 stores in advance information indicating what kind of notification to the user when the communication terminal device 50 is a slave unit and can communicate with the master unit. ing. Further, the temporary memory 19 also stores in advance information indicating what kind of notification is to be given to the user when the communication terminal device 50 is a parent device and can communicate with the child device. The communicable notification unit 53 reads information related to the notification from the temporary memory 19 depending on whether the communication terminal device 50 is operating as a parent device or a child device, and notifies the user according to the information. .

(Communication monitoring)
As described above, the local communication unit 17 performs communication (call) between the parent device and the child device. Specifically, although communication is performed based on the Bluetooth standard, the present invention is not limited to this, and any other applicable communication standard may be used. The local communication unit 17 can communicate not only the call voice itself but also various information related to the call such as a telephone number stored in the subscriber information card 14 and information on the operation of the communication terminal device 50 by the user.

  The local communication unit 17 can also monitor whether communication with another connected communication terminal device 50 is possible. For example, it is determined that communication is impossible when a signal from the communication terminal device 50 on the partner side cannot be received, such as when reply data cannot be received after waiting for a certain time after data is transmitted to the partner.

(Judgment of communication possible)
Immediately after the start of communication, the parent device and the child device are sufficiently close to each other and can communicate with each other. Here, it is assumed that the user takes out the handset. When the slave unit is sufficiently separated from the master unit, radio waves do not reach between the slave unit and the master unit. That is, the communication terminal device 50 cannot receive a signal from the other party. In communication according to the Bluetooth standard, it is possible to receive a signal that is periodically transmitted and a reply signal that indicates that something has been transmitted to the other party. Therefore, if the signal cannot be received for a certain period of time, the local communication unit 17 determines that communication with the other party is no longer possible. That is, it is determined that the communication partner has gone out of the communicable range.

  When the local communication unit 17 determines that communication is disabled, the local communication unit 17 notifies the communication disabled warning unit 52 of the fact. The communication disabling warning unit 52 determines whether the communication terminal device 50 is a parent device or a child device based on the result of parent-child determination by the parent-child determination unit 51. Below, the example in which the communication terminal device 50 is a subunit | mobile_unit is demonstrated.

(Warning that communication is not possible)
The communication impossibility warning unit 52 reads information indicating what kind of warning is issued to the user when the communication terminal device 50 is a slave device from the temporary memory 19 of the communication terminal device 50. Normally, information set by the user operating the communication terminal device 50 is read. This information also differs depending on whether the manner mode is set in the communication terminal device 50 or not.

  The communication addition warning unit 52 issues a warning to the user based on the information read from the temporary memory 19. Specifically, the communication impermissible warning unit 52 warns the user that the communication terminal device 50 is currently unable to communicate by electronic sound, melody, vibration, or the like, as in the case of incoming calls.

(Notification that communication is possible)
Next, an example in which the slave unit and the master unit are sufficiently close to each other and can communicate with each other will be described. When the slave unit and the master unit are sufficiently close to each other, the local communication unit 17 can receive a signal from the partner side. Thereby, the local communication unit 17 determines that communication is possible by receiving a signal from the other party. If the local communication unit 17 determines that communication is possible, the local communication unit 17 notifies the communication enable notification unit 53 of the fact. Similar to the communication failure warning unit 52, the communication enable notification unit 53 knows whether the communication terminal device 50 is operating as a parent device or a child device based on the determination result by the parent / child determination unit 51. As a result, information indicating what kind of notification to the user is read from the temporary memory 19. Based on the read information, the communicable notification unit 53 notifies the user that communication with the parent device is currently possible.

(Function and effect)
When the user makes a mistake and goes out with the handset (only), the handset alone cannot make a call. Therefore, the user is very troubled. However, when the communication terminal device 50 operating as a slave unit cannot communicate with the master unit, it warns the user to that effect. By confirming this warning, the user of the communication terminal device 50 moves to a place where communication with the parent device is possible, so that the communication terminal device 50 can communicate with the parent device again. In other words, the user notices that he is trying to take out only the slave unit so that he can turn back. Therefore, it is possible to prevent the telephone from being unable to be communicated at the place of going out.

  Further, when the slave unit cannot communicate with the master unit, the master unit also warns the user to that effect. By confirming this warning, the user can know that the communication terminal device 50 can currently communicate with the parent device. Therefore, the user can know that the communication terminal device 50 can communicate with the parent device without bothering to confirm.

  When the child device can communicate with the parent device from a state where the child device cannot communicate with the parent device, the user is immediately notified of the fact. Thereby, the user can know that the telephone call using the handset is now possible. In addition, the parent device can be notified with the child device, and can immediately recognize that the child device may start a call.

  Parents and children often act together while on the go. If the parent has a parent device and the child has a child device, one public network line using the subscriber information card 14 can be shared by a plurality of people (that is, the communication terminal device 50). Therefore, for example, when a parent has a parent device and a child goes out with a child device, the child device warns the child when the child is about to leave the parent. In addition, when the parent and the child are in a separate action, the parent and child can be notified of each other if they approach each other.

  The communication addition warning unit 52 issues different warnings to the user depending on whether or not the communication terminal device 50 is communicating with the parent device. Therefore, the communication terminal device 50 can inform the user of the operation status of the communication terminal device 50 when receiving a warning.

[Embodiment 4]
A third embodiment according to the present invention will be described below with reference to FIGS.

(Communication terminal device 60)
FIG. 6 is a block diagram showing a main configuration of a communication terminal apparatus 60 according to the fourth embodiment of the present invention. As illustrated in FIG. 6, the communication terminal device 60 of the present embodiment is configured to further include a charge state detection unit 61 and a user notification unit 62 in addition to the communication terminal device 1 illustrated in FIG. 1.

(Charge state detector 61)
The charging state detection unit 61 determines whether or not the communication terminal device 60 is in a charging state. Specifically, it is detected whether or not a current of a predetermined value or more is supplied from the external power source to the communication terminal device 60. When a current of a predetermined value or more is supplied, the charging state detection unit 61 determines that the communication terminal device 60 is in a charging state. On the other hand, when the electric current more than the predetermined value is not supplied, the charging state detection unit 61 determines that the communication terminal device 60 is not in the charging state. Therefore, the charging state detection unit 61 detects that the communication terminal device 60 is in a charged state, for example, when the communication terminal device 60 is connected to the charging connector.

(User notification unit 62)
The user notification unit 62 notifies the user that the state of the communication terminal device 60 has changed. The user notification unit 62 notifies the user through the output device 11 that can be sensed by visual, auditory, and tactile senses such as a liquid crystal display, an organic EL (Electro Luminescence) display, an LED (Light Emitting Diode), a speaker, and a vibrator. .

  For example, the user notification unit 62 displays a predetermined message such as “Card inserted” on the screen of the communication terminal device 60. If the subscriber information card is not inserted, the communication terminal device 60 operates as a slave unit that can be connected to the master unit. If the subscriber information card is inserted, the communication terminal device 60 operates as a parent device that receives a connection from the communication terminal device 60 as a child device. That is, the user notification unit 62 notifies the user whether the communication terminal device 60 is operating as a parent device or a child device.

(Processing of the user notification unit 62)
The user notification unit 62 notifies the user of the state of the communication terminal device 60 based on information from the card insertion determination unit 15 and the charging state detection unit 61. The processing executed by the user notification unit 62 at this time will be described below with reference to FIG. FIG. 7 is a flowchart illustrating an example of a flow of processing executed by the communication terminal device 60 when connected to the charging connector. Below, the user notification part 62 demonstrates the example which notifies a user of the state of the communication terminal device 60 via a light emitting diode (LED).

(Use of LED)
The communication terminal device 60 includes an LED (not shown). If it will be in a charging state, the communication terminal device 60 will notify a user that it is in a charging state by lighting this LED. The user notification unit 62 uses an LED indicating a charging state in order to notify the user whether it is operating as a parent device or executing as a child device.

(Determination of charge status)
The user connects the communication terminal device to the charging connector. Thereby, the charging state detection part 61 determines whether the electric current was supplied from the external power supply and the communication terminal device 60 was in the charging state (step S71). If it is determined that the battery is in the charged state, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted into the card interface 13 of the communication terminal device 60 (step S72). When the subscriber information card 14 is inserted, the communication terminal device 60 operates as a master unit. Therefore, the user notification unit 62 lights a color (for example, red) indicating that the communication terminal device 60 is a parent device on the LED. Thereby, the user notification unit 62 notifies the user that the communication terminal device 60 is being charged and is operating as a parent device (step S73).

  On the other hand, when the subscriber information card 14 is not inserted into the card interface 13, the communication terminal device 60 operates as a slave unit. Therefore, the user notification unit 62 lights the LED in a color (for example, green) indicating that the communication terminal device 60 is a slave unit. As a result, the user notification unit 62 notifies the user that the communication terminal device 60 is being charged and is operating as a slave (step S74).

(LED color)
In the communication terminal device 60, the color of the LED may remain unchanged from the initial setting. Alternatively, the user may be able to change to a favorite color. At this time, the user inputs the LED color when the communication terminal device 60 is operating as a parent device and the LED color when the communication terminal device 60 is operating as a child device through the input device 10, respectively. Set to. The user notification unit 62 may use a display device other than the LED when notifying the user whether the communication terminal device 60 is a parent device or a child device. For example, a character, figure, color, or the like for determining whether the communication terminal device 60 is a parent device or a child device may be displayed on a predetermined display such as a liquid crystal display or an organic EL display.

(Function and effect)
As described above, the user notification unit 62 notifies the user whether or not the subscriber information card is inserted in the communication terminal device 60 when the communication terminal device 60 is in a charged state. When the communication terminal device 60 is in a charged state, the user is likely to keep the communication terminal device 60 in a certain place. Therefore, the communication terminal device 60 is unlikely to be taken out somewhere. Thereby, the communication terminal device 60 can inform the user of the operating state of the communication terminal device 60 when the communication terminal device 60 is kept in a certain place.

  Note that the user notification unit 62 may notify the user whether or not the subscriber information card 14 is inserted in the communication terminal device 60 when the communication terminal device 60 is no longer charged. At this time, the user notification unit 62 notifies the user whether or not the subscriber information card 14 is inserted in the communication terminal device 60 when the communication terminal device is no longer charged. If the communication terminal device 60 is not charged, the user can carry the communication terminal device 60 freely. Therefore, the user notification unit 62 can know the operating state of the communication terminal device 60 when the user can freely carry the communication terminal device 60. Thereby, the communication terminal device 60 is a child device, for example, and can prevent the user from holding out the communication terminal device 60 that cannot communicate with the outside alone.

[Embodiment 5]
A fifth embodiment according to the present invention will be described below with reference to FIGS.

(Communication terminal device 80)
FIG. 8 is a block diagram showing a main configuration of a communication terminal apparatus 80 according to the fifth embodiment of the present invention. As shown in FIG. 8, the communication terminal device 80 of the present embodiment is configured to further include an incoming call state detection unit 81 in addition to the communication terminal device 60 shown in FIG. 6.

(Incoming state detection unit 81)
The incoming state detection unit 81 detects an incoming state in the communication terminal device. That is, it is determined whether or not the communication terminal device 80 has received an incoming call.

(Processing of the user notification unit 62)
The user notification unit 62 notifies the user of the state of the communication terminal device 60 based on information from the card insertion determination unit 15, the charging state detection unit 61, and the incoming state detection unit 81. Processing executed by the user notification unit 62 at this time will be described below with reference to FIG.

  FIG. 9 is a flowchart illustrating an example of a flow of processing executed by the communication terminal device 80 when it is disconnected from the charging connector. Below, the user notification part 62 demonstrates the example which notifies a user of the state of the communication terminal device 80 by vibrating the communication terminal device 80 through a vibrator.

  Communication terminal device 80 operates as a slave unit. That is, the subscriber information card 14 is not inserted into the card interface 13. The user takes this communication terminal device 80 to the outside. In order to prevent this, the user notification unit 62 operates the vibrator to notify the user that the communication terminal device 80 is away from the charging connector.

(Charge state detection)
The user removes the communication terminal device 80 from the charging connector. Thereby, the charge state detection part 61 determines whether the electric current supply from an external power supply was complete | finished (step S91). When it is determined that the charging state has ended, the card insertion determination unit 15 determines whether or not the subscriber information card 14 is inserted in the card interface 13 of the communication terminal device 80 (step S92). When the subscriber information card 14 is inserted, the communication terminal device 80 operates as a master unit. Therefore, the user notification unit 62 notifies the user nothing.

(Notification to user)
On the other hand, when the subscriber information card 14 is not inserted, the incoming state detection unit 81 determines whether or not the communication terminal device is in the incoming state (step S93). When in the incoming state, the user is likely to use the communication terminal device 80 as a slave unit. Therefore, the user notification unit 62 notifies the user nothing. On the other hand, when not in an incoming state, the user is likely to take the communication terminal device 80 to the outside. Therefore, the user notification unit 62 notifies the user that the subscriber information card 14 is not inserted into the card interface 13 of the communication terminal device 80 by operating the vibrator (step S94).

(Notification variant)
The user may set a certain waiting time for the communication terminal device 80 after the communication terminal device 80 is disconnected from the charging connector until the vibrator operates. During the waiting time, when the user performs some operation on the communication terminal device 80 by pressing a button on the communication terminal device 80 or opening and closing a clamshell type housing, the user notification unit 62 Thereafter, the vibrator need not be operated. Moreover, the user notification part 62 may emit some notification sound from a speaker instead of operating a vibrator. Alternatively, the LED may be turned on. Further, some information indicating whether or not the subscriber information card 14 is inserted into the card interface 13 may be displayed on a predetermined display such as a liquid crystal display or an organic EL display.

(Function and effect)
As described above, the user notification unit 62 notifies the user whether or not the subscriber information card 14 is inserted in the communication terminal device 60 when the communication terminal device 60 is in an incoming state. As a result, when a user makes a call using the communication terminal device 60, the user can determine whether the communication terminal device 60 currently used is a parent device or a child device connected to the parent device. I can know. Therefore, the user can surely know in what form the communication terminal device 60 is used to make a call.

(Synchronization start part 103)
The synchronization start unit 103 starts data synchronization between the parent device 100 and the child device 100a and between the parent device 100 and the child device 100b. For example, when the user presses a predetermined button provided in the parent device 100, the synchronization start unit 103 detects the press and starts data synchronization.

(Data synchronization unit 104)
The data synchronization unit 104 synchronizes data stored in the data storage unit 101 between the parent device 100 and the child device 100a and between the parent device 100 and the child device 100b. That is, the data stored in the data storage unit 101 is transmitted to the child device 100a and the child device 100b through the local communication unit 17. Furthermore, the data transmitted from the subunit | mobile_unit 100a and the subunit | mobile_unit 100b are received, and are stored in the data storage part 101. FIG.

(Slave unit 100a)
As shown in FIG. 11, the subunit | mobile_unit 100a is the structure which is further provided with the data storage part 101a, the connecting point memory | storage part 102a, and the data synchronizer 104a in the communication terminal device 1 shown in FIG.

(Data storage unit 101a)
The data storage unit 101a stores various data managed by the slave device 100a. The data storage unit 101a is a part of the memory in the slave device 100a.

(Connection destination storage unit 102)
The connection destination storage unit 102 stores information related to the parent device to which the child device 100a is connected. The connection destination storage unit 102a is a part of the memory in the child device 100a.

(Data synchronization unit 104a)
The data synchronization unit 104a synchronizes data stored in the data storage unit 101a with the parent device 100. That is, the data stored in the data storage unit 101 a is transmitted to the parent device 100 through the local communication unit 17. Furthermore, the data transmitted from the parent device 100 is received and stored in the data storage unit 101a.

(Slave unit 100b)
As shown in FIG. 11, slave unit 100b is configured to further include data storage unit 101b, connection destination storage unit 102b, and data synchronization unit 104b in communication terminal device 1 shown in FIG. Since these members are the same as the various members provided in the child device 100a, the description thereof is omitted.

(Data synchronization processing)
Data synchronization processing between the parent device 100 and the child device 100a will be described below with reference to FIG. FIG. 12 is a flowchart for explaining the flow of data synchronization processing between the parent device 100 and the child device 100a.

(Start processing)
First, the parent device 100 and the child device 100a are locally connected to each other (steps S121 and S122). The user presses a predetermined button that is provided in the parent device 100 and instructs to start data synchronization. This depression is detected by the synchronization start unit 103, and data synchronization is started (step S123). Specifically, the synchronization start unit 103 requests the slave device 100a to start data synchronization (step S124). This request is received by the synchronization start unit 103a of the slave device 100a, and the start of data synchronization is received (step S125).

(Transmission of terminal identification ID)
The data synchronization unit 104a of the slave device 100a reads the terminal identification ID for identifying the slave device 100a from the temporary memory 19, and transmits it to the master device 100 (step S126). The terminal identification ID transmitted from the child device 100a is received by the data synchronization unit 104 in the parent device 100 and stored in the connection destination storage unit 102 (step S127). Next, the data synchronization unit 104 reads the terminal identification ID for identifying the connection destination storage unit 102 from the temporary memory 19 and transmits it to the child device 100a (step S128). The terminal identification ID transmitted from the parent device 100 is received by the data synchronization unit 104ba in the child device 100a and stored in the connection destination storage unit 102a (step S129).

  Through the above processing, parent device 100 and child device 100a acquire and store information on the connected terminals.

(Data transmission)
When the terminal identification ID is exchanged, in the slave unit 100a, the data synchronization unit 104a reads the data from the data storage unit 101a and transmits it to the master unit 100 stored in the connection destination storage unit 102a (step S130). Thereby, in base unit 100, data synchronization unit 104 combines the data transmitted from slave unit 100a with the data of base unit 100 stored in data storage unit 101. That is, base unit 100 starts data synchronization processing A shown in FIG. On the other hand, handset 100a starts data synchronization processing B shown in FIG.

(Example of data)
An example of data that each of the parent device 100 and the child device 100a has will be described below with reference to FIG. FIG. 15 is a diagram illustrating data held by each terminal, (a) is a diagram illustrating an example of data stored in the data storage unit 101 by the parent device 100, and (b) is a diagram illustrating data stored in the data storage unit 101. FIG. 7 is a diagram illustrating an example of data stored in the data storage unit 101a by the slave device 100a, and (c) is a diagram illustrating an example of data stored in the data storage unit 101 by the master device 100 after data synchronization. It is.

(Data synchronization processing A)
Data synchronization executed by base unit 100 will be described below with reference to FIG. FIG. 13 is a flowchart showing the flow of data synchronization processing executed by base unit 100.

  First, the data synchronization unit 104 determines whether data of a certain item is stored in the data storage unit 101 (step S131). When the determination result in step S131 is “false” (No), the data synchronization unit 104 next determines whether or not the data of this item has been received from the child device 100a (step S132). When the determination result in step S132 is “false” (No), the data synchronization unit 104 does nothing because the data of this item does not exist in either the parent device 100 or the child device 100a. That is, the process shown in FIG.

(Uses data of handset 100a)
On the other hand, when the determination result in step S132 is “true” (Yes), that is, when it is determined that the data of this item is received from the child device 100a, the data synchronization unit 104 uses the data of the child device 100a. It is decided to do (step S133). That is, the received data of the slave unit 100 a is stored in the data storage unit 101. In FIG. 15, Mr. B's telephone number data corresponds to this example.

(Uses data of base unit 100)
On the other hand, when the determination result in step S131 is “true” (Yes), that is, when it is determined that the data of a certain item is stored in the data storage unit 101 of the parent device 100, the data synchronization unit 104 Next, it is determined whether the data of this item has been received from the child device 100a (step S134). When the determination result in step S134 is “false” (No), the data synchronization unit 104 determines to use the data of the parent device 100 as it is for the data of this item (step S137). Therefore, the data stored in the data storage unit 101 is not changed as it is. In FIG. 15, Mr. A's telephone number data corresponds to this example.

(If equal, use data of base unit 100)
On the other hand, when the determination result in step S134 is “true” (Yes), the data synchronization unit 104 determines whether the two data are equal (step S135). At this time, when the determination result in step S135 is “true” (Yes), that is, when it is determined that the data of the parent device 100 and the data of the child device 100a are equal, the data synchronization unit 104 relates to this item. Then, it is determined to use the data of base unit 100 as it is (step S137). Therefore, the data stored in the data storage unit 101 is not changed as it is. In FIG. 15, Mr. C's telephone number data corresponds to this example.

(User selects when data is different)
On the other hand, when the determination result in step S135 is “false” (Yes), that is, when determining that the data of the parent device 100 is different from the data of the child device 100a, the data synchronization unit 104 determines which data. It cannot be determined by itself whether it should be stored in the data storage unit 101. Therefore, base unit 100 requests the user to select which data to select. For example, in the base unit 100, the input / output control unit 12 displays a message such as “Please select data to be used” on the output device 11 as a display. The user selects which data is to be stored in the data storage unit 101 through the input device 10. The input / output control unit 12 receives the selection result and notifies the data synchronization unit 104 of the selection result. Upon receiving this notification, the data synchronization unit 104 determines whether or not the user has selected the data of the parent device 100 (step S136).
When the determination result in step S136 is “true” (Yes), the data synchronization unit 104 determines to use the data of the parent device 100 as it is for this item (step S137). Therefore, the data stored in the data storage unit 101 is not changed as it is. In FIG. 15, Mr. D's telephone number data corresponds to this example.

(Uses data of handset 100a according to user selection)
On the other hand, when the determination result in step S136 is “false” (No), the data synchronization unit 104 determines to use the data of the child device 100a for this item (step S133). Therefore, the data of the parent device 100 stored in the data storage unit 101 is overwritten with the received data of the child device 100a.

  By the above processing, the data stored in the data storage unit 101 of the parent device 100 becomes as shown in FIG. As shown in this figure, after data composition, phone number data of Mr. A, Mr. B, and Mr. D are stored in the data storage unit 101 of the parent device 100 as data of the parent device 100. On the other hand, Mr. C's telephone number data is stored as data of the slave unit 100a.

(Data synchronization processing B)
In master device 100, data synchronization unit 104 reads data of master device 100 from data storage unit 101, and transmits the data to slave device 100a in which information is stored in connection destination storage unit 102. In slave device 100a, data synchronization unit 104 receives the data transmitted from master device 100 and combines it with the data of slave device 100a stored in data storage unit 101a.

  Data synchronization executed by the slave device 100a will be described below with reference to FIG. FIG. 14 is a flowchart showing the flow of data synchronization processing executed by the slave device 100a. First, the data synchronization unit 104a receives the data transmitted from the connection destination storage unit 102 and stores it in the temporary memory 19 (step S141). Next, the data synchronization unit 104a specifies the item of the received data, and determines whether or not the data related to the data of this item is stored in the data storage unit 101a (step S142). When the determination result in step S142 is “false” (No), the data synchronization unit 104a determines to use the received data of the parent device 100 (step S143). Therefore, the data of the child device 100a stored in the data storage unit 101a is overwritten with the received data of the parent device 100. In FIG. 15, Mr. A's telephone number data corresponds to this example.

(If equal, use data of base unit 100)
On the other hand, when the determination result in step S142 is “true” (Yes), the synchronization start unit 103a determines whether the two data are equal (step S144). At this time, when the determination result in step S144 is “true” (Yes), that is, when it is determined that the data of the parent device 100 is equal to the data of the child device 100a, the synchronization start unit 103a As for the data, it is determined that the data of the slave device 100a is used as it is (step S146). Therefore, the data stored in the data storage unit 101 is not changed as it is. In FIG. 15, the phone number data of Mr. B and Mr. C correspond to this example.

(User selects when data is different)
On the other hand, when the determination result in step S144 is “false” (Yes), that is, when determining that the data of the parent device 100 is different from the data of the child device 100a, the data synchronization unit 104 determines which data. It cannot be determined whether or not the data should be stored in the data storage unit 101a. Therefore, handset 100a causes the user to select either data. The user selects which data is to be stored in the data storage unit 101 a through the input device 10. The input / output control unit 12 receives the selection result and notifies the data synchronization unit 104a. Upon receiving this notification, the data synchronization unit 104a determines whether or not the user has selected the data of the slave device 100a (step S145).
At this time, when the determination result in step S145 is “true” (Yes), the data synchronization unit 104a determines to use the data of the child device 100a as it is for this item (step S146). Therefore, the data stored in the data storage unit 101a is not changed as it is. In FIG. 15, Mr. D's telephone number data corresponds to this example.

(Uses data of base unit 100 by user's selection)
On the other hand, when the determination result in step S144 is “false” (No), the data synchronization unit 104a determines to use the received data of the parent device 100 for this item (step S143). Therefore, the data of the child device 100a stored in the data storage unit 101a is overwritten with the received data of the parent device 100.

(Function and effect)
As described above, the data synchronization unit 104a of the slave device 100a synchronizes the data stored in the master device 100 with the data stored in the slave device 100a. Therefore, the slave device 100a can use the data stored in the master device 100. Thereby, the user who replaces the subscriber information card 14 and switches the parent device 100 and the child device 100a can refer to the same data in either communication terminal device. Therefore, it is possible to improve convenience when the user switches between the parent device 100 and the child device 100a.

  In addition, data synchronization can be achieved between a plurality of communication terminal devices owned by the user. Accordingly, in principle, the same data can be used in the latest state in any terminal device. For example, a user uses a certain communication terminal device for a day, and after use, the data (such as outgoing / incoming history and received mail) updated on that day is synchronized with other communication terminal devices. Thereby, when the user uses another communication terminal device the next day, the latest update data used on the previous day can be used.

(Transfer received data)
Base unit 100 receives data such as e-mail from the outside through a public network. The received data can be transmitted from the parent device 100 to the child device 100a via the local connection network. At this time, in base unit 100, public network communication unit 16 once outputs the received data to local communication unit 17. As a result, the local communication unit 17 analyzes the received data from the received data, and stores the analysis result in the temporary memory 19. For example, the e-mail header information is analyzed, and the sender e-mail address is extracted. Furthermore, based on the information stored in the connection destination storage unit 102, it is determined whether there is a slave unit connected to the master unit 100.

  If the connected child device cannot be identified, the parent device 100 does nothing. On the other hand, if there is a connected slave unit, the local communication unit 17 reads information related to data transfer to the slave unit, which is stored in advance in the temporary memory 19. The local communication unit 17 compares the analysis result (for example, the sender mail address) of the received data with the transfer setting information read from the temporary memory 19. If the information does not match, the local connection unit 18 does not transfer the received data to the slave unit. If both pieces of information match, the local connection unit 18 transfers the data to the slave unit.

(About setting transfer setting information)
Master device 100 may arbitrarily set identification information of received data to be transferred for each slave device registered in connection destination storage unit 102. The received data identification information includes, for example, the sender mail address of the received mail, the subject of the received mail, the type of data automatically distributed from the server, and the like. A transfer destination may be designated for each type of content transmitted by the push delivery service. For example, the master device 100 may be set to transfer news articles to the slave device 100a and television guide information to the slave device 100b.

(Function and effect)
The data synchronization unit 104 transfers the data received by the parent device 100 to the child device 100a. At this time, the base unit 100 can specify the reception data to be transferred to each slave unit. That is, when the master unit 100 is connected to a plurality of slave units, the data synchronization unit 104 distributes and transfers the data to the slave unit 100a and the slave unit 100a according to the contents of the data. For example, data relating to the user's work is transferred only to the child device 100a, and data relating to the user's private data is transferred only to the child device 100b. As a result, the user can selectively use the slave unit 100a and the slave unit 100b depending on the application. In addition, by using a communication terminal device that is not normally used and in which the subscriber information card 14 is not inserted as a slave unit, there is no need to newly add a function for browsing received data to the slave unit.

[Embodiment 7]
A seventh embodiment of the present invention will be described below with reference to FIGS.

(Communication terminal device 160)
FIG. 16 is a block diagram showing a main configuration of a communication terminal apparatus 160 according to the seventh embodiment of the present invention. As illustrated in FIG. 16, the communication terminal device 160 according to the present embodiment is configured to further include an operation setting unit 161 in addition to the communication terminal device 1 illustrated in FIG. 1.

(action mode)
Communication terminal device 160 operates based on the set operation mode. The operation modes here include a normal operation mode and a forced slave mode. The normal operation mode is an operation mode in which the communication terminal device 160 operates as a slave when the subscriber information card 14 is inserted into the card interface 13 like the communication terminal device in the first embodiment described above. . The forced slave mode is an operation mode in which the communication terminal device 160 operates as a slave regardless of whether or not the subscriber information card 14 is inserted into the card interface 13.

(Operation mode setting)
The user inputs information regarding the operation mode of the communication terminal device 160 through the input device 10. The input / output control unit 12 receives this input and stores it in the temporary memory 19. The user may input this setting by pressing various buttons provided on the communication terminal device 160. Alternatively, the operation mode may be designated through a setting screen displayed on a predetermined display.

(Operation setting unit 161)
The operation setting unit 161 sets the operation mode of the communication terminal device 160. The operation setting unit 161 sets the operation mode selected by the user stored in the temporary memory 19 in the communication terminal device 160. That is, communication terminal apparatus 160 is set in communication terminal apparatus 160 as to which of the normal operation mode and the forced slave mode is to be operated.

(Operation mode confirmation process)
The initialization stage of the parent-child connection process in the communication terminal device 160 will be described below with reference to FIG. FIG. 17 is a flowchart illustrating an example of a process flow when the communication terminal device 160 in which the forced slave mode is set forcibly operates as a slave and connects to the master.

  The operation setting unit 161 confirms the operation mode setting stored in the temporary memory 19 (step S171). Thereby, the operation setting unit 161 determines whether or not the operation mode is the forced child device mode (step S172). When the determination result in step S172 is “false” (No), that is, when the operation mode is the normal operation mode, the communication terminal apparatus 160 performs a normal connection initialization process. That is, when the subscriber information card 14 is inserted into the card interface 13, it operates as a slave unit and is locally connected to the communication terminal device 160 as the master unit.

  On the other hand, when the determination result in step S172 is “true” (Yes), that is, when the operation mode is the forced slave mode, the communication terminal device 160 is forcibly executed as a slave. That is, without determining whether or not the subscriber information card 14 is inserted in the card interface 13, a local connection with the communication terminal device 160 executed as the parent device is immediately attempted.

  Since the subsequent processing is the same as the processing shown in FIG. 2, the description thereof is omitted.

(Function and effect)
As described above, when the communication terminal device 160 is set to operate as a slave unit, it communicates directly with the master unit unconditionally regardless of whether or not the subscriber information card 14 is inserted. To do. Therefore, the user can use the communication terminal device 160 in which the subscriber information card 14 is inserted as a slave unit.

(Communication from outside)
When the communication terminal device 160 operates in the forced slave mode, the public network communication unit 16 can communicate with the outside through the public line network. When communication such as an incoming call occurs from the outside to the subscriber set in the subscriber information card 14, the public network communication unit 16 requests the operation setting unit 161 to switch the communication network.

  In response to a request from the public network communication unit 16, the operation setting unit 161 temporarily saves information regarding the current operation mode in the temporary memory 19. Further, the currently set operation mode is reset. As a result, the communication terminal device 160 does not operate as a slave unit, and the public network communication unit 16 communicates with the outside through the public line network.

  When this communication is completed, the public network communication unit 16 requests the operation setting unit 161 to return to the operation mode. Upon receiving this request, the operation setting unit 161 returns the operation mode to the mode temporarily saved in the temporary memory 19. Communication terminal device 160 operates according to the restored operation mode. For example, the operation setting unit 161 initializes the local communication unit 17 according to the restored operation mode.

(Process flow)
A processing flow at this time will be described below with reference to FIG. FIG. 18 is a flowchart showing a flow of processing executed by the communication terminal device 160 when an external communication request is generated.

  When a communication request from the outside is generated (step S181), the public network communication unit 16 confirms various information stored in the subscriber information card 14 inserted in the card interface 13, and the communication request is received. It is determined whether or not the device is for the device itself.

  As an example of the communication request, there is communication that comes from the outside, such as an incoming call of a telephone and an incoming of a short mail. Furthermore, it corresponds to the case where the public network communication unit 16 periodically connects to the public line network and detects a communication request from the server, such as transmission / reception of electronic mail and transmission / reception of chat data.

(Evacuation of operation mode)
When an external communication request is generated, the operation setting unit 161 saves the mode setting stored in the temporary memory 19 to the storage location for saving the mode in the temporary memory 19 (step S182). Next, the communication terminal device 160 switches the communication function of the own device to the public line network (step S183). Accordingly, the public network communication unit 16 communicates with the outside through the public line network. Specifically, communication processing relating to incoming calls or incoming short mails is performed (step S184).

  When the communication is completed, the public network communication unit 16 requests the operation setting unit 161 to return to the operation mode. As a result, the processing control unit 161 reads out the operation mode before communication with the outside starts from the storage location for mode saving in the temporary memory 19 and resets it (step S185).

  Thereafter, the operation setting unit 161 re-executes the procedure shown in FIG. Thereby, the communication terminal device 160 is restored to the state before the external communication request is generated (step S186).

  As described above, the communication terminal device 160 can smoothly receive calls and mails using the subscriber information card 14 even when a mode for forcibly operating as a slave unit is set. Furthermore, after the communication is completed, the original operation mode can be restored.

(Function and effect)
As described above, in the present embodiment, the communication terminal device 100 uses the subscriber information card 14 as long as communication occurs from outside even when operating as a slave unit, and is a normal communication that is not a slave unit. The terminal device 100 operates. Therefore, communication from the outside can be reliably received. Furthermore, when receiving communication from the outside, the operation mode of the communication terminal device 100 is automatically switched. Therefore, it is not necessary for the user to switch the operation mode. As a result, the user can immediately perform the intended communication without consuming unnecessary time.

[Embodiment 8]
The eighth embodiment according to the present invention will be described below with reference to FIGS. 19 and 20.

(Communication system 6)
FIG. 19 is a diagram showing a schematic configuration of a communication system 5 according to the eighth embodiment of the present invention. As shown in this figure, the communication system 5 includes a master unit 190 that can communicate with a base station through a public network, and slave units 190a and 190b that are locally connected to the master unit and can communicate with each other. Yes.

(Base unit 190)
Details of the parent device 100, the child device 100a, and the child device 100b included in the communication system 6 will be described below with reference to FIG. As shown in FIG. 19, base unit 190 of the present embodiment further includes content storage unit 191, content reproduction unit 192, content information transmission unit 193, and reproduction data transmission unit 194 in addition to communication terminal device 60 shown in FIG. 6. It is the structure equipped with.

(Content storage unit 191)
The content storage unit 191 stores various contents that can be reproduced by the communication terminal device 190. The content storage unit 191 is a part of the memory in the parent device 190.

(Content playback unit 192)
The content reproduction unit 192 reads the content requested to be reproduced from the slave device 190a from the content storage unit 191 and reproduces it. As a result, the content playback unit 192 creates playback data representing what is output from the output device 11 (for example, sound) when the content is played back. The same applies when there is a request from the slave unit 190b.

(Content information transmission unit 193)
The content information transmission unit 193 transmits the content list stored in the content storage unit 191 to the child device 190a in response to a request from the child device 190a. The same applies when there is a request from the slave unit 190b.

(Reproduction data transmission unit 194)
The reproduction data transmission unit 194 transmits the reproduction data generated by the content reproduction unit 192 to the child device 190a. The same applies to the slave unit 190b.

(Slave unit 190a)
As shown in FIG. 19, the handset 190a includes a reproduction data reception unit 191a, a reproduction data reproduction unit 192a, a content information acquisition unit 193a, and a content selection instruction unit 194a.

(Reproduction data receiving unit 191a)
The reproduction data receiving unit 191 a receives the reproduction data transmitted from the reproduction data transmission unit 194 of the parent device 190 and stores it in the temporary memory 19.

(Reproduction data reproduction unit 192a)
The reproduction data reproducing unit 192a reads the reproduction data received by the reproduction data receiving unit 191a from the temporary memory 19 and reproduces it. Thereby, the reproduction data reproduction unit 192a outputs the result of reproducing the content (sound, video, etc.) to the output device 11.

(Content information acquisition unit 193a)
The content information acquisition unit 193a acquires a list of contents managed by the parent device 190 from the parent device 190. Specifically, the content information acquisition unit 193a requests the parent device 190 to transmit a list of contents stored in the content storage unit 191 to the child device 190a. Thus, the content information acquisition unit 193a receives the content list transmitted from the parent device 190 and stores it in the content storage unit 191a.

(Content selection instruction unit 194a)
The content selection instruction unit 194a instructs the parent device 190 to play back the content selected by the user from the content list on the parent device 190.

(Slave unit 190b)
As shown in FIG. 19, the handset 190b includes a reproduction data reception unit 191b, a reproduction data reproduction unit 192b, a content information acquisition unit 193b, and a content selection instruction unit 194b. Since these members included in the slave unit 190b are the same as the members included in the slave unit 190a, description thereof is omitted.

(Request for music data list)
FIG. 20 is a flowchart showing a flow of processing when the child device 190a acquires and reproduces the created sound data reproduced by the parent device 190. In the example described below, master device 190 stores a list of music data in content storage unit 191. In the slave device 190a, the content information acquisition unit 193a requests the communication terminal device 190 to transmit the music data list to the slave device 190a (step S201). In response to this request, in the parent device 190, the content information transmission unit 193 reads a list of music data from the content storage unit 191 and transmits it to the child device 190a. In the slave unit 190 a, the transmitted music data list is received by the content information acquisition unit 193 a and stored in the temporary memory 19.

(Song selection and playback request)
In the slave unit 190a, the input / output control unit 12 reads out the music data list stored in the temporary memory 19, and displays information on the music included in the list on the output device 11 such as a display. As a result, the user selects the target music (content) through the input device 10. The input / output control unit 12 accepts the selection by the user and notifies the information to the content selection instruction unit 194a. The content selection instruction unit 194a requests the parent device 190 to reproduce the music data selected by the user (step S202).

  In response to this request, in the parent device 190, the content reproduction unit 192 activates an application that can reproduce the music data instructed by the content selection instruction unit 194a, thereby reproducing the music data. Thereby, the content reproduction unit 192 generates sound data (reproduction data) indicating the reproduced sound. The reproduction data transmission unit 194 transmits sound data to the child device 190a. In the slave unit 190 a, the transmitted reproduction data is received by the reproduction data receiving unit 191 a and stored in the temporary memory 19. The sound data stored in the temporary memory 19 is reproduced by the reproduction data reproduction unit 192a, so that sound is output to the output device 11 such as headphones or speakers (step S204). Thereby, the user listens to the reproduced sound.

  In parent device 190, content reproduction unit 192 determines whether or not reproduction of the music data has been completed (step S205). When it is determined not to end, the content reproduction unit 192 repeats reproduction of the music data. On the other hand, when determining that the operation has been completed, the operation setting unit 161 of the parent device 190 notifies the child device 190a of the fact (step S205). The slave device 190a that has received this notification executes a reproduction end process (step S206). Thereby, the subunit | mobile_unit 190a displays a standby screen, for example. Similarly, the master unit 190 performs a reproduction end process (step S206).

(Function and effect)
In this way, the reproduction data receiving unit 191a acquires reproduction data generated by the parent device 190 reproducing the content. Thereby, in the subunit | mobile_unit 190a, the content of the main | base station 190 can be indirectly reproduced by reproducing | regenerating reproduction data, for example. Therefore, even if the child device 190a cannot reproduce the content of the parent device 190, the content of the parent device 190 can be reproduced. That is, the child device 190a can use the content of the parent device 190. Therefore, each terminal device does not have to have the same content. As a result, the memory of the slave unit 190a can be saved.

  Also, copyrighted data such as music data stored in the content storage unit 191 of the parent device 190 can be reproduced not only by the parent device 190 but also by the child device 190a connected to the main device 190. Therefore, the user can enjoy the same content not only through the parent device 190 but also through the child device 190a.

(Secure data transfer)
Next, an example in which the parent device 190 transmits secure data (content data) that is copyright-protected to the child device 190a will be described below with reference to FIG. FIG. 21 is a flowchart illustrating an example of a flow of processing executed by each of the parent device 190 and the child device 190a when the parent device 190 transmits secure data to the child device 190a.

  First, the slave device 190a prepares to receive secure data (step S211). Next, base unit 190 prepares to transmit secure data. As a result, the base unit 190 is ready to transmit secure data, and the local communication unit 17 of the base unit 190 transmits the secure data to the slave unit 190a (step S213). In the slave unit 190a, the local communication unit 17 receives secure data. At this time, the local communication unit 17 of the slave unit 190a determines whether or not the reception of secure data has been completed (step S213). When it is determined not to be completed, the local communication unit 17 continues to receive secure data. On the other hand, when determining that it has been completed, the parent device 190 deletes the secure data transmitted to the child device 190a from the content storage unit 191 (step S214). Master device 190 notifies slave device 190a that secure data has been deleted. Receiving this notification, the slave unit 190a executes a reproduction end process (step S215). Thereby, the subunit | mobile_unit 190a displays a standby screen, for example. Similarly, the parent device 190 performs a reproduction end process (step S216).

(Function and effect)
As described above, in this embodiment, even secure data having a copyright can be moved or copied between the parent device 190 and the child device 190a. Therefore, each terminal device does not have to prepare secure data such as the same music data individually. This prevents the user from being forced to spend extra money.

(Example content)
The “content” described above means, for example, various data that can be played back or browsed on a communication terminal device (parent device, child device). Therefore, music data, moving image data, image data, text data, and the like correspond to content. The content is data obtained by the communication terminal device regardless of whether it is paid or free. The communication terminal device can be obtained by downloading these data through the Internet, receiving the data as an attached file of a mail, or communicating with other devices such as a personal computer. Alternatively, data created by the user in the communication terminal device can also be used as content.

[Embodiment 9]
The ninth embodiment according to the present invention will be described below with reference to FIGS.

(Communication system 7)
FIG. 22 is a diagram showing a schematic configuration of the communication system 7 according to the present invention. The communication system 7 shown in this figure includes a master unit X that can communicate with a base station through a public network and slave units A and B that are locally connected to the master unit X and can communicate with each other. Details of parent device X, child device A, and child device B included in the communication system will be described below with reference to FIG.

(Base X)
As shown in FIG. 22, the base unit X of the present embodiment has a configuration in which the communication terminal device 30 shown in FIG. 3 further includes a remaining value storage unit 221 and a remaining value notification unit 222. Base device X has a so-called electronic money function. Therefore, the user can use the parent machine X to make a purchase or pay a service fee.

  In the parent device X, the subscriber information card 14 is inserted into the card interface 13. Further, the slave unit A and the slave unit B are fully connected to the master unit X. Therefore, the slave unit A and the slave unit B are registered as connection sources in the connection destination storage unit 102 of the master unit X.

(Balance value storage unit 221)
The balance value storage unit 221 stores a balance value of electronic money managed by the parent device X. The user can use the balance of the value stored in the balance value storage unit 221 through the parent device X as electronic money for shopping and payment of a service usage fee.

(Remaining value notification unit 222)
The balance value notification unit 222 notifies the slave unit that is permanently connected to the master unit X of the balance value of the electronic money stored in the balance value storage unit 221 of the master unit X. With this notification, in the example shown in FIG. 22, the parent device X, the child device A, and the child device B can share and manage the balance value of the electronic money.

(Slave unit A)
In the handset A, the subscriber information card 14 is not inserted into the card interface 13. In the connection destination storage unit 102 of the child device A, the parent device X is registered as a connection destination. The handset A includes a balance value storage unit 221a and a balance value notification unit 222a. The balance value storage unit 221a of the slave unit A stores a balance value of electronic money managed by the slave unit A. The balance value notification unit 222a notifies the base unit X of the electronic money balance value of the child device A stored in the balance value storage unit 221a.

(Slave unit B)
In the slave unit B, the subscriber information card 14 is not inserted into the card interface 13. In the connection destination storage unit 102 of the child device B, the parent device X is registered as a connection destination. This handset B includes a balance value storage unit 221b and a balance value notification unit 222b. The balance value storage unit 221b of the slave unit B stores a balance value of electronic money managed by the slave unit B. The balance value notification unit 222b notifies the base unit X of the electronic money balance value of the child device B stored in the balance value storage unit 221b.

(Before starting processing)
Before sharing the electronic money balance value, each of the parent device X, the child device A, and the child device B stores only its own balance value. A specific example of the balance value managed by each terminal device at this time will be described below with reference to FIG.

  FIG. 23 is a diagram showing the balance values managed by the master unit X, the slave unit A, and the slave unit B before sharing each other's balance value. It is a figure which shows the balance value managed, (b) is a figure which shows the balance value which the subunit | mobile_unit A manages, (c) shows the balance value which the subunit | mobile_unit B manages. FIG.

  As shown in FIG. 23A, the base unit X stores “3000” in the balance value storage unit 221 as the balance value of the master unit X. As shown in FIG. 23B, the slave unit A stores “12000” in the balance value storage unit 221a as the balance value of the slave unit A. As shown in FIG. 23 (c), the slave unit B stores “5000” in the balance value storage unit 221 b as the balance value of the slave unit B.

(Connect base unit X and handset A)
With reference to FIG. 24, a description will be given below of the flow of processing when the parent device X, the child device A, and the child device B share the balance value managed by each of them. FIG. 24 is a flowchart showing the flow of processing when the parent device X, the child device A, and the child device B share the balance value managed by each of them.

  First, an example of sharing the balance value between the parent device X and the child device A will be described below. In the parent device X and the child device A, both connection determination units 32 determine whether or not local connection can be established. If the connection is possible based on the determination result, the parent device X and the child device A are locally connected to each other (step S241).

(Shares the balance of base unit X and handset A)
When this connection is established, the balance value notification unit 222 in the master unit X reads the balance value of the master unit X from the balance value storage unit 221 and transmits it to the slave unit A. In the slave unit A, the balance value notification unit 222a receives the balance value transmitted from the master unit X, and stores it in the balance value storage unit 221a as the balance value of the master unit X. Next, the balance value notification unit 222a in the slave unit A reads the balance value of the slave unit A from the balance value storage unit 221a and transmits it to the master unit X. In the master unit X, the balance value notification unit 222 receives the balance value transmitted from the slave unit A, and stores it in the balance value storage unit 221 as the balance value of the slave unit A.

  Through the above processing, first, the parent device X and the child device A share each other's balance value (step S242). At this time, the slave unit A notifies the master unit X of the balance value of the electronic money currently managed by the slave unit A. As a result, the base unit X stores the information in the subscriber information storage unit 31. If the balance value can be normally shared, the parent device X and the child device A disconnect the local communication unit 17.

(Balance value after sharing)
FIG. 25 is a diagram illustrating the balance values managed by the master unit X, the slave unit A, and the slave unit B after the master unit X and the slave unit A share each other's balance value. ) Is a diagram showing the balance value managed by the master device X, (b) is a diagram showing the balance value managed by the slave device A, and (c) is a diagram managed by the slave device B. It is a figure which shows the balance value which is doing.

  As shown in FIG. 25, the base unit X stores the balance value of the master unit X and the slave unit A in the balance value storage unit 221. Further, similarly to the master unit X, the slave unit A stores the balance value of the master unit X and the slave unit A in the balance value storage unit 221a. That is, the parent device X and the child device A normally share the balance value of both. On the other hand, the slave unit B stores only the balance value of the slave unit B in the balance value storage unit 221b. That is, the slave unit B has not yet shared the balance value between the master unit X and the slave unit A.

(Connect base unit X and handset B)
Referring to FIG. 24 again, the flow of processing in which the parent device X and the child device B share the balance value of each other will be described. In the parent device X and the child device B, both the connection determination units 32 determine whether or not they can be locally connected to each other. Based on this determination result, if connection is possible, the parent device X and the child device B are locally connected to each other (step S243).

(Shares the balance of base unit X and handset B)
When this connection is established, the balance value notification unit 222 in the master unit X reads the balance value of the master unit X from the balance value storage unit 221 and transmits it to the slave unit B. In the slave unit B, the balance value transmitted from the master unit X is received by the balance value notification unit 222b and stored in the balance value storage unit 221b as the balance value of the master unit X. Next, the balance value notification unit 222b in the slave unit B reads the balance value of the slave unit A from the balance value storage unit 221b and transmits it to the master unit X. In the parent device X, the remaining value transmitted from the child device B is received by the remaining value notification unit 222 and stored in the remaining value storage unit 221 as the remaining value of the child device B.

Through the above processing, the parent device X and the child device B share each other's balance value (step S244). At this time, the slave unit B notifies the master unit X of the balance value of the electronic money currently managed by the slave unit B. As a result, the base unit X stores the information in the subscriber information storage unit 31. If the balance value can be shared normally, base unit X and handset B disconnect the local connection (remaining balance value after sharing)
FIG. 26 is a diagram illustrating balance values managed by the master unit X, the slave unit A, and the slave unit B after the master unit X and the slave unit B share each other's balance value. ) Is a diagram showing the balance value managed by the master device X, (b) is a diagram showing the balance value managed by the slave device A, and (c) is a diagram managed by the slave device B. It is a figure which shows the balance value which is doing.

  As shown in FIG. 25A, the base unit X stores the balance value of the base unit X, the slave unit A, and the slave unit B in the balance value storage unit 221. Further, as shown in FIG. 25 (b), the slave unit A stores the balance value of the master unit X and the slave unit A in the balance value storage unit 221a. On the other hand, as shown in FIG. 25C, the slave unit B stores the balance value of the master unit X and the slave unit B in the balance value storage unit 221b. That is, the parent device X and the child device B normally share each other's balance value.

(Check if there is a new slave unit registration)
The base unit X has a balance value managed by each slave unit stored in the subscriber information storage unit 31 and a balance value managed by the base unit X stored in the balance value storage unit 221. Are compared with each other. As a result, a slave unit that does not completely share the balance is searched.

(Update the balance value of the already connected slave unit)
When searching for a slave unit that does not share the balance, the connection determination unit 32 determines whether or not a local connection can be established with the slave unit. If the connection is possible, the local connection unit 18 locally connects the parent device X and the child device. As a result, a new slave unit is registered in the master unit X.

(Balance value of handset A)
The balance value notification unit 222 of the parent device X determines whether or not a new child device is registered in the connection destination storage unit 102 (step S245). For example, as shown in FIGS. 25 (a) and 25 (b), the parent machine X and the child machine A still do not share the balance value. That is, the balance value of the slave unit B cannot be shared. Accordingly, in the parent device X, the child device A is registered as a new child device. As a result, the remaining value notification unit 222 of the parent device X reads the remaining value of the child device B managed by the parent device X from the remaining value storage unit 221 and notifies the child device A of the remaining value. In the slave unit A, the balance value notification unit 222a receives the transmitted balance value and stores it in the balance value storage unit 221a as the balance value of the slave unit B.

(Balance value of handset B)
Further, as shown in FIGS. 25 (a) and 25 (c), the parent machine X and the child machine B still have insufficient sharing of the balance value. That is, the balance value of the slave unit B cannot be shared. Therefore, the slave unit B is registered in the master unit X as a new slave unit. Accordingly, the balance value notification unit 222 of the parent device X reads the balance value of the child device A managed by the parent device X from the balance value storage unit 221 and notifies the child device B of the balance value. In the slave unit B, the balance value notification unit 222b receives the transmitted balance value and stores it in the balance value storage unit 221b as the balance value of the slave unit A.

  Through the above processing, the parent device X, the child device A, and the child device B completely share each other's balance value as shown in FIG. That is, each of the parent device X, the child device A, and the child device B is “3000” as the balance value of the parent device X, “12000” as the balance value of the slave device A, and “ 5000 "is managed respectively.

(Output balance value)
Master device X can notify the user of the balance value stored in balance value storage unit 221. This example will be described below with reference to FIG. FIG. 28 is a diagram showing an external appearance of the parent device X that can notify the user of the balance value. As shown in FIG. 28, the parent device X includes a balance display button 281 as the input device 10. Further, a display 282 is provided as the output device 11.

  In FIG. 28, “remaining money display” is displayed on the lower left of the display screen of the display 282 of the parent device X. This display shows the function of the balance display button 281. The function here is a function executed by the communication terminal device 280 when the user presses the balance display button 281. That is, when the user presses the balance display button 281, the input / output control unit 12 displays the balance value stored in the balance value storage unit 221 of the parent device X on the display 282.

  With reference to FIG. 29, the following describes the flow of processing when the master unit X displays the balance value on the display 282. FIG. 29 is a flowchart for explaining the processing flow when the parent device X displays the balance value of electronic money on the display 282.

(Waiting for input)
First, the input / output control unit 12 waits for an input by the user (step S291). Next, the input / output control unit 12 determines whether or not an instruction to display the balance has been made by the user (step S292). Specifically, it is determined whether or not the user has pressed the balance display button 281. When determining that the user has pressed the balance display button 281, the input / output control unit 12 reads the balance value managed by the parent device X from the balance value storage unit 221 (step S 293). The input / output control unit 12 displays the read balance value on the display 282 (step S294).
(Example of balance value to be displayed)
An example of the balance value displayed on the display 282 by the input / output control unit 12 will be described below with reference to FIG. FIG. 30 is a diagram illustrating an example of the balance value displayed on the display 282 by the input / output control unit 12. As shown in this figure, the input / output control unit 12 displays the remaining value of the parent device X, the child device A, and the child device B stored in the remaining value storage unit 221 on the display 282. By confirming this display, the user can know the balance value of the parent device X stored in the parent device X. In addition, the balance of the slave unit A and the slave unit B stored in the master unit X can also be known.

(Function and effect)
As described above, in the present embodiment, the parent device X shares information on the balance value of electronic money with the child device A. Therefore, the user who uses the parent device X can check the balance value of the child device A in the parent device X. Further, the user who uses the slave unit A can also check the balance value of the master unit X in the slave unit A.
