If it is attached, the SIM card 19 storing the same contractor information is attached to each of the devices 1 and 2, but the mobile phone terminal 1 enjoys a service from the wireless communication carrier. The wireless communication device 2 cannot enjoy the service from the wireless communication carrier.

(Operation based on validity / invalidity of contractor information)
First, FIG. 6 is a flowchart showing the operation of determining whether or not the service can be received in each of the devices 1 and 2 based on the above-described valid / invalid information. The control units 14 and 34 of the mobile phone terminal 1 and the wireless communication device 2 operate according to the flowchart shown in FIG.

  As an example, the operation of the control unit 14 on the mobile phone terminal 1 side will be described. First, when the main power supply of the mobile phone terminal 1 is detected, the control unit 14 starts the flowchart shown in FIG. In step S1, valid / invalid information stored in the memory 27 is read and controlled via the control / processing unit 25 of the SIM card 19 mounted on the SIM card unit 18. Then, based on the read valid / invalid information, it is determined whether or not contractor information to be “valid” is stored on the mobile phone terminal 1 side.

  If it is determined that the contractor information to be “valid” is stored on the mobile phone terminal 1 side based on the valid / invalid information, the control unit 14 proceeds to step S2 and in step S2 Recognizing that the contractor information is “valid”, in step S3, based on the valid contractor information, reception of the service from the wireless communication carrier is started.

  On the other hand, when it is determined that the contractor information to be “invalid” is stored on the mobile phone terminal 1 side based on the valid / invalid information, the control unit 14 proceeds to step S4. In step S4, it is recognized that the contractor information is “invalid”, and in step S5, based on the invalid contractor information, the service from the wireless communication carrier is not enjoyed. Control each part.

  Note that, similarly to the control unit 14 of the mobile phone terminal 1, the control unit 34 of the wireless communication device 2 performs an operation for determining whether or not to receive the service based on the validity / invalidity information when the main power is turned on. .

(Effectiveness transfer)
Next, when the wireless communication device 2 that is set to “invalid” enjoys a service from a wireless communication carrier, the wireless communication device 2 receives the transfer of the validity of the contractor information from the mobile phone terminal 1 It is necessary to make the contractor information of “valid”. The flowchart in FIG. 7 shows a flow until the validity of the contractor information is transferred from the mobile phone terminal 1 to the wireless communication device 2.

  In this case, the user currently gets in the automobile with the mobile phone terminal 1 whose contractor information is “valid”, and the contactless IC card unit 12 of the mobile phone terminal 1 is placed on the automobile. The wireless communication device 2 is brought close to the non-contact IC card reader / writer unit 32.

  When the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32 approach within a few centimeters, communication is started between the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32, and the flowchart of FIG. It will start.

  When the flowchart of FIG. 7 starts, in step S11, each control unit 22 of the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32 determines whether or not non-contact communication is possible with each other. Determine. This determination is held in the terminal identification information (terminal ID) of the mobile phone terminal 1 stored in the memory 23 of the non-contact IC card unit 12 and in the memory provided in the non-contact IC card reader / writer unit 32. This is performed by exchanging and comparing the device identification information (device ID) of the wireless communication devices 2 that are present.

  When it is in a state where non-contact communication is not possible, in step S16, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that non-contact communication is not possible, or the wireless communication device 2 The control unit 34 controls the display unit 35 to display a message indicating that contactless communication is not possible.

  On the other hand, when non-contact communication is possible, in step S12, the control unit 14 on the mobile phone terminal 1 side checks the validity of the contractor information between the mobile phone terminal 1 and the wireless communication device 2. It is determined whether or not transfer is possible.

Specifically, the control unit 14 of the mobile phone terminal 1
1. The contractor information stored in the memory of the SIM card 19 of both the mobile phone terminal 1 and the wireless communication device 2 match;
2. The transfer of the validity of the contractor information is permitted,
3. The contractor information between the mobile phone terminal 1 and the wireless communication device 2 is determined by determining whether or not only one of the conditions is satisfied that the validity is confirmed. It is determined whether or not the validity can be transferred.

  If all the above conditions are not satisfied, in step S15, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that the validity of the contractor information cannot be transferred, or the wireless communication device 2 The control unit 34 controls the display unit 35 to display a message indicating that the validity of the contractor information cannot be transferred.

  On the other hand, when all the above conditions are satisfied, in step S13, the control unit 14 of the mobile phone terminal 1 stores the contractor information currently stored as “valid” in the memory 27 of the SIM card 19, The SIM card unit 18 is controlled so as to be rewritten with “invalid” contractor information, and the control unit 34 of the wireless communication device 2 stores the contractor information currently stored as “invalid” in the memory 27 of the SIM card 19. Is rewritten to “valid” contractor information.

  When the transfer of the validity of the contractor information is completed, in step S14, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that the transfer of the validity of the contractor information is completed. Alternatively, the control unit 34 of the wireless communication device 2 controls the display unit 35 to display a message indicating that the transfer of the validity of the contractor information has been completed.

  As a result, the validity of the contractor information is transferred from the mobile phone terminal 1 to the wireless communication device 2, and the mobile phone terminal 1 side to which the SIM card 19 in which the “invalid” contractor information is stored is attached. However, while the service provided by the wireless communication carrier cannot be enjoyed, the wireless communication carrier 2 on the side of the wireless communication device 2 in which the SIM card 19 storing the “valid” contractor information is installed is You can enjoy the services you provide.

(Return validity)
Next, when the mobile phone terminal 1 enjoys the service provided by the wireless communication provider, it is necessary to return the validity of the contractor information transferred to the wireless communication device 2 to the mobile phone terminal 1. The flowchart in FIG. 8 shows a flow until the validity of the contractor information is returned from the wireless communication device 2 to the mobile phone terminal 1.

  In this case, the user gets into the automobile with the mobile phone terminal 1 whose contractor information is currently “invalid”, and the contactless IC card unit 12 of the mobile phone terminal 1 is placed on the automobile. The wireless communication device 2 is brought close to the non-contact IC card reader / writer unit 32.

  When the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32 come within a few centimeters, communication is started between the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32, and the flowchart of FIG. It will start.

  When the flowchart of FIG. 8 starts, in step S21, each control unit 22 of the non-contact IC card unit 12 and the non-contact IC card reader / writer unit 32 determines whether or not non-contact communication is possible with each other. Determine. This determination is held in the terminal identification information (terminal ID) of the mobile phone terminal 1 stored in the memory 23 of the non-contact IC card unit 12 and in the memory provided in the non-contact IC card reader / writer unit 32. This is performed by exchanging and comparing the device identification information (device ID) of the wireless communication devices 2 that are present.

  When it is in a state where non-contact communication is not possible, in step S27, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that non-contact communication is not possible, or the wireless communication device 2 The control unit 34 controls the display unit 35 to display a message indicating that contactless communication is not possible.

  On the other hand, when non-contact communication is possible, in step S22, the control unit 14 on the mobile phone terminal 1 side checks the validity of the contractor information between the mobile phone terminal 1 and the wireless communication device 2. It is determined whether it can be returned.

Specifically, the control unit 14 of the mobile phone terminal 1 performs 1. The contractor information stored in the memory of the SIM card 19 of both the mobile phone terminal 1 and the wireless communication device 2 match;
2. The transfer of validity of contractor information is permitted,
3. The contractor information between the mobile phone terminal 1 and the wireless communication device 2 is determined by determining whether or not only one of the conditions is satisfied that the validity is confirmed. It is determined whether or not the validity can be transferred.

  If all the above conditions are not satisfied, in step S26, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that the validity of the contractor information cannot be returned, or the wireless communication device 2 The display unit 35 controls the display unit 35 to display a message indicating that the validity of the contractor information cannot be returned.

  On the other hand, if all the above conditions are satisfied, in step S23, the control unit 34 on the wireless communication device 2 side that currently has “valid” contractor information is displayed on the wireless communication device 2 side. It is determined whether or not the validity of the contractor information can be returned by determining whether or not the service provided by the wireless communication carrier is being enjoyed.

  If the control unit 34 on the wireless communication device 2 side determines that the validity cannot be returned for reasons such as enjoying the service provided by the wireless communication carrier, the control of the mobile phone terminal 1 is performed in step S26. The unit 14 controls the display unit 15 to display a message that the validity of the contractor information cannot be returned, or the message that the control unit 34 of the wireless communication device 2 cannot return the validity of the contractor information. Is controlled on the display unit 35.

  On the other hand, when it is determined that the validity can be returned by the control unit 34 on the wireless communication device 2 side, the control unit 34 of the wireless communication device 2 stores the memory 27 of the SIM card 19 in step S24. The SIM card unit 38 is controlled so as to rewrite the contractor information currently stored as “valid” to the contractor information “invalid”, and the control unit 14 of the mobile phone terminal 1 controls the memory 27 of the SIM card 19. In addition, the SIM card unit 18 is controlled so that the contractor information currently stored as “invalid” is rewritten to the “valid” contractor information.

  When the return of the validity of the contractor information is completed, in step S25, the control unit 14 of the mobile phone terminal 1 controls the display unit 15 to display a message indicating that the return of the validity of the contractor information is completed. Alternatively, the control unit 34 of the wireless communication device 2 controls the display unit 35 to display a message indicating that the validity of the contractor information has been returned.

  As a result, the validity of the contractor information is returned from the wireless communication device 2 to the mobile phone terminal 1, and the mobile phone terminal 1 side to which the SIM card 19 in which the “valid” contractor information is stored is attached. On the other hand, on the side of the wireless communication device 2 in which the SIM card 19 in which the “invalid” contractor information is stored is installed, the service provided by the wireless communication operator can be enjoyed. You will not be able to enjoy the services provided by.

(Automatic return of validity)
In this way, in the wireless communication system of the embodiment, by transferring and returning the validity of the contractor information, only one of the devices can enjoy the service provided by the wireless communication operator. However, it is assumed that the user forgets to return the transferred validity.

  For example, the user gets in the car with the mobile phone terminal 1 having the “valid” contractor information, and transfers the validity of the contractor information to the in-vehicle wireless communication apparatus 2, so that the wireless communication apparatus 2 is However, it is assumed that the user forgets to return the contractor information from the wireless communication device 2 to the mobile phone terminal 1 when getting off the vehicle. In this case, the user continues to have the mobile phone terminal 1 (= the mobile phone terminal 1 that cannot enjoy the service provided by the wireless communication carrier) having no effectiveness.

  In order to prevent such inconvenience, in the wireless communication system of the embodiment, the memory 27 in each SIM card 19 indicates whether the device is a master device or a non-master device (slave device). Information (attribute information) is recorded. When the validity of the contractor information is transferred to the slave device, if the distance between the master device and the slave device is more than a predetermined distance, the contractor information transferred to the slave device The validity is automatically returned to the master device.

  The flowchart of FIG. 9 shows the flow of the automatic return operation of the validity of the contractor information. Hereinafter, this automatic return operation will be described by taking as an example a case where the mobile phone terminal 1 is defined as a master device and the wireless communication device 2 is defined as a slave device.

  In the flowchart of FIG. 9, the control unit 14 on the mobile phone terminal 1 side which is a master device detects that the contractor information on the mobile phone terminal 1 side is “invalid” and is a slave device. The control unit 34 on the wireless communication device 2 side starts when it detects that the contractor information on the wireless communication device 2 side is “valid”.

  In other words, the control units 14 and 34 of the devices 1 and 2 detect that the validity of the contractor information is being transferred to the side of the wireless communication device 2 that is the slave device. The flowchart starts. In this case, the control units 14 and 34 of the devices 1 and 2 respectively start communication of the short-range wireless communication between the devices 1 and 2 by controlling communication of the short-range wireless communication transmission / reception units 13 and 33 such as Bluetooth. .

  In step S31, whether or not the controllers 14 and 34 of the devices 1 and 2 are capable of short-range wireless communication between the devices 1 and 2 via the short-range wireless communication transceivers 13 and 33, respectively. Is determined. If short-distance wireless communication is not possible between the devices 1 and 2, in step S35, the control unit 14 of the mobile phone terminal 1 may automatically return the validity together with a message indicating that short-distance wireless communication is not possible. A message indicating that the validity cannot be displayed on the display unit 15 or that the control unit 34 of the wireless communication device 2 cannot automatically return the validity together with the message indicating that the short-range wireless communication cannot be performed. Is controlled on the display unit 35. When such an error message is displayed, the user can connect the mobile phone terminal 1 and the wireless communication device to a distance where the contactless IC card unit 12 and the contactless IC card reader / writer unit 32 can perform contactless wireless communication. Accordingly, the validity of the contractor information is returned from the wireless communication device 2 to the mobile phone terminal 1.

  Next, when short-range wireless communication is possible between the devices 1 and 2, the control units 14 and 34 of the devices 1 and 2 are connected between the short-range wireless communication transmitting and receiving units 13 and 33 in step S <b> 32. The short-range wireless communication transmitting / receiving units 13 and 33 are controlled so as to intermittently perform communication at predetermined time intervals. Thereby, when communication is normally performed between the short-range wireless communication transmission / reception units 13 and 33, the mobile phone terminal 1 and the wireless communication device 2 exist within a range where this short-range wireless communication is possible. Can recognize each other.

  In step S32, the control units 14 and 34 of the devices 1 and 2 determine whether or not communication is normally performed between the short-range wireless communication transmission / reception units 13 and 33, so that the short-range wireless communication is performed. It is determined whether or not the mobile phone terminal 1 and the wireless communication device 2 exist within the possible range.

  If it can be determined that the mobile phone terminal 1 and the wireless communication device 2 exist within the range where short-range wireless communication is possible, the control units 14 and 34 of the devices 1 and 2 are set in step S33. When the waiting time elapses, the short-range wireless communication transmitting / receiving units 13 and 33 are controlled so that communication is performed again when the waiting time elapses. Thereby, when the mobile phone terminal 1 and the wireless communication device 2 exist within the range where short-range wireless communication is possible, communication is intermittently performed between the short-range wireless communication transmission / reception units 13 and 33. It will be. In this example, the communication between the short-range wireless communication transmitting / receiving units 13 and 33 is intermittently performed. However, the communication may be continuously performed.

  Next, when it is determined that the mobile phone terminal 1 or the wireless communication device 2 has deviated from the range in which the short-range wireless communication is possible, the control units 14 and 34 of the devices 1 and 2 are contracted in step S34. Perform automatic return of information validity.

  That is, in this example, the mobile phone terminal 1 is a master device, and the wireless communication device 2 is a slave device. In addition, the validity of the contractor information is still transferred to the wireless communication device 2 that is the slave device. The memory 27 of the SIM card 19 on the wireless communication device 2 side currently stores valid / invalid information that makes the contractor information “valid”, and the memory 27 of the SIM card 19 on the mobile phone terminal 1 side. Currently stores valid / invalid information that makes the contractor information “invalid”.

  For this reason, the control unit 14 on the mobile phone terminal 1 side stores the contractor information stored in the memory 27 of the SIM card 19 at the timing when the short-range wireless communication with the wireless communication device 2 cannot be performed. The valid / invalid information to be “invalid” is rewritten to valid / invalid information to “valid”. At the same time, the control unit 34 on the wireless communication device 2 side contractor information stored in the memory 27 of the SIM card 19 at the timing when short-range wireless communication with the mobile phone terminal 1 can no longer be performed. The valid / invalid information with “valid” is rewritten to valid / invalid information with “invalid”.

  As a result, when the distance between the mobile phone terminal 1 and the wireless communication device 2 is more than a predetermined distance, the validity of the contractor information transferred to the wireless communication device 2 that is the slave device is mastered. It can be automatically returned to the mobile phone terminal 1, which is a device. For this reason, it is possible to prevent the inconvenience of carrying around the master device in which the contractor information is invalid and the service of the wireless communication carrier cannot be enjoyed.

  In this example, the validity of the contractor information is returned from the slave device to the master device. However, this applies to the device that received the transfer of validity regardless of the master device or slave device. The validity may be returned to the device to which the validity is transferred (= the validity may be returned between the validity transfer source and the transfer destination).

[Effect of the embodiment]
As is clear from the above description, the wireless communication system according to the present embodiment has the same contractor information issued by the wireless communication provider to the SIM card of each device, and the validity / Valid / invalid information indicating invalidity is stored, the validity / invalidity information of the device on the side receiving the service provided by the wireless communication carrier is set to “valid”, and the service provided by the wireless communication carrier is provided. The above-mentioned validity / invalidity information of the device that is not enjoyed is “invalid” (= when the contractor information of one device is “valid”, the contractor information of the other device is “invalid”. ).

  As a result, a plurality of wireless communication devices can enjoy a communication service based on a single contractor information. For this reason, in order to enjoy communication services with a plurality of wireless communication devices, it is possible to eliminate the need for a contract with a wireless communication operator that is individually required for each device.

  In addition, since the service provided by the wireless communication carrier can be enjoyed only by one device for which the contractor information is valid, the service can be enjoyed simultaneously by a plurality of devices based on the same contractor information. Inconvenience can be prevented.

  In addition, since the same contractor information is stored in advance in each device, it is possible to eliminate the need for attaching / detaching a medium such as a SIM card in which the contractor information with the wireless communication carrier is recorded.

  In addition, when the contractor information of the slave device is valid, when the distance between the master device and the slave device is more than a predetermined distance, the contractor information on the master device side is set to “valid” By setting the contractor information on the slave device side to “invalid” (= automatically returning the validity of the contractor information to the master device side), the contractor information on the master device side is set to “invalid” It is possible to prevent the inconvenience of being left standing.

  In the description of the above-described embodiment, the mobile phone terminal 1 is used as the mobile terminal device. However, this may be a PHS phone (PHS: Personal Handyphone System) or a PDA device having a wireless communication function (PDA: Personal Handyphone System). Other portable terminal devices such as a digital assistant), a wireless communication card, and a notebook personal computer device to which the wireless communication card is connected may be used.

  In addition, it is assumed that the contractor information with the wireless communication carrier is recorded in the SIM card. However, the contractor information may be stored in a memory or the like built in each device, as described above. An effect can be obtained.

  Finally, the above-described embodiment is merely disclosed as an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and according to the design or the like, as long as the technical idea according to the present invention is not deviated from other embodiments.
