  The PHS radio unit 220 is connected to the antenna 260, receives radio waves from the base station 300 via the antenna 260, and transmits radio waves to the base station 300. The PHS radio unit 220 includes a baseband unit and a codec unit, converts a high-frequency signal from the antenna 260 into a data signal, converts the data signal into a high-frequency signal, and sends the data signal to the antenna 260. Data can be sent and received between them.

  The control unit 230 controls each unit of the card reading device 200.

  Next, the operation of the card system according to the embodiment of the present invention will be described.

  The card system according to the embodiment of the present invention has a PHS communication function in the card 100, and the location information of the card 100 (simultaneous calling area in which the card 100 exists) is sent to the location registration server 400 via the base station 300. Manage intensively. In addition, when the use of the card is stopped due to the loss of the card 100, the authentication server 500 holds information for prohibiting the use of the card, thereby taking an appropriate measure against unauthorized use of the card 100. It is configured to be able to.

  First, when the card 100 starts to be used (for example, when it is newly purchased and starts operation), or when the card 100 moves to a new general call area by handoff, the card 100 stores its own location information. Request to be registered. The location registration server 400 includes location information of the card 100 (simultaneous call area where the card 100 exists), unique information of the card 100 (for example, unique information (PS number, pre-assigned to the card 100 and the card reader 200) PSID), telephone number, etc.) are recorded in the location registration database 410 as location information.

  Next, the location registration server 400 queries the authentication server 500 for the authentication information of the card 100. The authentication server 500 refers to the card authentication database 510 and searches whether the information of the card 100 that has received the inquiry is registered in the card authentication database 510 as a use-prohibited card. The card authentication database 510 stores information on cards that are prohibited from being used due to reasons such as losing the card (see FIG. 4). If the card is registered as a use-prohibited card in the card authentication database 510, the location registration server 400 is notified of information related to the card. In response to this notification, the location registration server 400 sends a notification that the card is prohibited from being used to the card 100 and the card reader 200 in the same general call area via the base station 300. To do. This notification prohibits the use of the card 100. In addition, when a card 100 with a high degree of risk is about to be used, a report is made to a security company with which a contract is made in advance.

  FIG. 4 shows an example of the contents of the card authentication database 510.

  Corresponding to the telephone number assigned to the card that is prohibited to be used, the position and the danger level of the card are recorded. The risk level is set higher as it becomes more malicious, for example, when it is illegally used repeatedly until the use prohibition is registered.

  For example, in the upper part of the table, it is indicated that the risk of the card 100 having the general calling area “PA01” and the telephone number “07001234567” is high and “10”.

  FIG. 5 is a flowchart showing a location registration process performed by the card 100.

  The card 100 determines whether or not there is a change in the general call area (process 1001). If there is no change in the general call area where the card 100 exists, the process waits without performing the subsequent processes. If it is determined that there has been a change in the general call area due to the card 100 being moved and handoff being performed, the processing proceeds to processing 1002. This determination is made with reference to the ID of the general call area included in the CSID that is information of the base station 300 in the control channel message communicated between the card 100 and the base station 300 at the time of handoff.

  In process 1002, a location registration request signal is transmitted to the base station 300 to request that information regarding the location of the card 100 be registered in the location registration database 410 of the location registration server 400.

  When the location registration to the location registration server 400 is completed, the location registration server 400 transmits to the card 100 that the registration of location information has been completed and information about the card acquired from the authentication server 500.

  When the card 100 receives the information on the card (process 1003), the card 100 stores the received information on the card in a storage device such as a memory provided in the control unit 130. Next, information on the card (usage conditions such as the card usage period, and the fact that the card cannot be used if the use prohibition is registered) is displayed on the display unit 140 (process 1004).

  When the use of the card is prohibited, it is displayed that the card cannot be used, and the control unit 130 can be operated so that the card cannot be used.

  Further, only when the location registration is completed and the card can be used is displayed and it is confirmed that the card can be used, the controller 130 can use the card. It may be operated.

  FIG. 6 is a flowchart showing a location registration process performed by the card reader 200.

  The card reader 200 determines whether there is a change in the general call area (process 2001). If there is no change in the general call area where the card reader 200 exists, the process waits without performing the subsequent processes. If it is determined that the general calling area has been changed by moving the card reading device 200 and performing handoff, the processing shifts to processing 2002. The determination of the change of the general call area is made with reference to the ID of the general call area included in the CSID, similarly to the card 100.

  In the process 2002, a location registration request signal is transmitted to the base station 300 to request that information regarding the location of the card reader 200 be registered in the location registration database 410 of the location registration server 400.

  When the location registration to the location registration server 400 is completed, the location registration server 400 includes the cards 100 whose use is prohibited among the cards 100 existing in the general call area where the registered card reader 200 exists. Information is transmitted to the card reader 200.

  When the card reading device 200 receives the information on the card 100 (process 2003), first, the information on the card 100 prohibited to be used, which is already stored in a storage device such as a memory provided in the control unit 230, is used. Delete (process 2004). Next, the newly received information of the card 100 that is prohibited from being used is stored. (Processing 2005).

  Thus, when a new card information is received, the already stored card information is deleted and the newly received card information is stored. Therefore, it is necessary to increase the storage capacity of the card reader 200. Absent.

  FIG. 7 is a flowchart showing the location registration processing of the card 100 performed on the base station side (location registration server 400 and authentication server 500).

  The base station 300 monitors whether there is a location registration request from the card 100 (process 1002 in FIG. 5) (process 3001). If there is no location registration request, this process is repeated until there is a request, and the system waits. When it is determined that there has been a location registration request, the process proceeds to processing 3002.

  In process 3002, the base station 300 requests the location registration server 400 to register information regarding the card 100 that has received the location registration request. Then, the location registration server 400 registers information such as a general calling area to which the card 100 that has received the location registration request belongs, a telephone number of the card 100, and the like in the location registration database 410.

  Next, the location registration server 400 requests the authentication server 500 to search for information on the card 100 that has received the location registration request (processing 3003).

  Upon receiving the search request, the authentication server 500 searches the card authentication database 510 based on the requested telephone number of the card 100, and determines whether or not registration of use of the card is prohibited. Determination is made (process 3004). If it is registered that the use is prohibited, the card of the telephone number is notified to the location registration server 400 that the use is prohibited (process 3005). If it is not registered that the use is prohibited, a notification indicating that the use is prohibited is sent to the location registration server 400 (process 3006).

  Next, when the location registration server 400 receives a notification that the use is prohibited from the authentication server 500, the card 100 and the card reading device 200 existing in the same general call area via the base station 300. In response, a notification to the effect that the use is prohibited is transmitted (processing 3007).

  The card use prohibition information is transmitted from the base station 300 by being included in optional data in the idle state of the paging channel. Therefore, information about the card can be broadcast to communication terminals (card 100 and card reader 200) existing in the same general call area.

  FIG. 8 is a flowchart showing the location registration processing of the card reader 200 performed on the base station side (location registration server 400 and authentication server 500).

  The base station 300 monitors whether or not there is a location registration request (process 2002 in FIG. 6) from the card reader 200 (process 4001). If there is no location registration request, this process is repeated until there is a request, and the system waits. When it is determined that there has been a location registration request, the process proceeds to processing 4002.

  In process 4002, the base station 300 requests the location registration server 400 to register information related to the card reader 200 that has received the location registration request. Then, the location registration server 400 registers information such as the general calling area to which the card reading device 200 belongs and the telephone number of the card reading device 200 in the location registration database 410.

  Next, the location registration server 400 requests the authentication server 500 to search for information on the cards 100 existing in the same simultaneous call area (process 4003).

  Upon receiving the search request, the authentication server 500 searches the card authentication database 510 based on the general call area where the card reader 200 exists, and the card 100 belonging to the general call area and whose use is prohibited is searched. Information is extracted, and the extracted information is sent to the location registration server 400. The location registration server 400 transmits the received information of the registered card 100 that is prohibited to use to the card reader 200 via the base station 300 (process 4004). The card information is individually transmitted from the base station 300 to the card reader 200 that has requested the location registration, but may be included in optional data in an idle state of the paging channel.

  Next, a process when the card 100 registered as being prohibited in the card authentication database 510 is about to be used will be described.

  FIG. 9 is a flowchart illustrating processing performed by the card reader 200 when an unauthorized card is about to be used.

  The card reading device 200 determines whether or not the card 100 has been read by the card communication unit 210 of the card reading device 200 (process 5001). If the card 100 is not read, this process is repeated until the card 100 is read, and the process waits. If it is determined that the card 100 has been read, communication with the card 100 is performed, and information (for example, a telephone number) of the card 100 is acquired (process 5002).

  Next, the use of the read card 100 is prohibited by referring to the information of the prohibited card acquired at the time of position registration (process 4004 in FIG. 8) or thereafter (process 3007 in FIG. 7). It is determined whether or not it is registered as a thing (process 5003). If use of the card is prohibited, the process proceeds to process 5004. If the use is not prohibited, the process proceeds to process 5007, the use of the card 100 is permitted, and a predetermined process (for example, a process such as debiting the amount of money from the card) is performed.

  In process 5004, the card risk level is referred to based on the card use prohibition information, and it is determined whether or not the risk level is greater than a preset value. When the degree of risk is larger than the predetermined value, the process proceeds to process 5006, and when the degree of risk is smaller than the predetermined value, the process proceeds to process 5005.

  In process 5005, the use of the card 100 is set to non-permitted. At this time, the fact that the card reader 200 cannot be used is transmitted to the card 100, and the fact may be displayed on the display unit 140 of the card 100.

  In process 5006, the PHS radio unit 220 of the card reading device 200 makes a call to a preset security company or the like to notify that a card with a high degree of risk has been used. At this time, the card can be either unusable or usable.
