Description

  The present invention relates to a mobile communication system such as a mobile phone system that performs system authentication using a subscriber ID stored in a mobile radio terminal device, for example.

  As is well known, a conventional mobile radio terminal device (Mobile station) has a built-in storage means in which a mobile unit number unique to a terminal body and a subscriber ID which is information for identifying a subscriber are written. Then, the mobile radio terminal device reads out the subscriber ID from the storage means at the time of location registration to the mobile communication network and at the time of outgoing / incoming calls, and transmits the subscriber ID to a control signal with the mobile communication network. Receive subscriber authentication from the mobile communication network. As a result, the mobile radio terminal device can stand by and waits for an incoming / outgoing call.

  This subscriber ID is written in the storage means built in the mobile radio terminal device to be used when the subscriber makes a contract with the mobile communication carrier. Also, in the above provider's system, the mobile station number and the subscriber ID of the mobile radio terminal device are managed on a one-to-one basis, and the subscriber ID cannot be moved to another MS or shared. It was.

  Therefore, when a subscriber uses a plurality of mobile radio terminal devices, it is necessary to make a contract with an operator for each mobile radio terminal device and to have a unique subscriber ID assigned to each mobile radio terminal device. For this reason, in addition to the inconvenience of using a separate telephone number for each subscriber ID, the subscriber has to bear a basic fee individually.

  On the other hand, in the next-generation mobile phone system, in order to eliminate the inconveniences described above, it is considered that the storage means for storing the subscriber ID is made into a memory card so that it can be attached to and detached from the mobile radio terminal device. ing. The memory card is referred to as a SIM (Subscriber ID Module) card, and it is considered to be standardly installed in all mobile radio terminal devices.

  The interface for mounting the SIM card is provided at an appropriate position of the mobile radio terminal device. When the SIM card is inserted into the interface, the mobile radio terminal device reads the subscriber ID written in the SIM card and reads it. It can be used to receive incoming calls from the mobile communication network.

  For this reason, when the subscriber changes the mobile radio terminal device to a new model or the like, the subscriber can use it by simply inserting the SIM card into the interface of the new model. In addition, since the SIM card can be replaced between mobile radio terminal devices, subscribers use a telephone for voice communication, a personal computer for data communication, a small mail terminal device, etc. without making a contract with a plurality of subscribers. Can be convenient.

  However, when using a plurality of mobile radio terminal devices properly, it is necessary to replace the SIM card each time, which is very troublesome. In general, since a telephone for voice communication is commonly used and it is necessary to wait for an incoming call, the SIM card needs to be mainly inserted into the telephone. For this reason, when using a personal computer for emergency data communication, a small mail terminal or the like, it is essential to return the SIM card to the telephone each time communication is completed, and for the subscriber to replace the SIM card. Was a burden.

On the other hand, conventionally, a method has been proposed in which wireless communication means are provided in the SIM card and the mobile wireless terminal device, and both communicate wirelessly to transmit the subscriber ID information stored in the SIM card to the mobile wireless terminal device. (For example, refer to Patent Document 1). However, in this method, it is necessary to always carry the SIM card, and there is a problem that the small SIM card may be lost or the location may be unknown.

If the person identification information SID has not been transmitted, the process proceeds to step 7f.

  In step 7h, the control unit 110 controls the second communication unit 102 to receive the subscriber identification information SID transmitted from the radio base station 200, and records this in the subscriber identification storage means 104b of the storage unit 104. The process proceeds to step 7b.

  When the mobile radio terminal apparatus 100 is turned off, as one of the end processes, a process for saving the subscriber identification information SID recorded in the subscriber identification storage unit 104b to the nonvolatile storage unit 105 is performed. Executed.

  Next, in the mobile communication system shown in FIG. 1, an operation when a call is made from the mobile radio terminal device 100 that does not store the subscriber identification information SID will be described. The sequence of this operation is shown in FIG.

  First, the mobile radio terminal apparatus 100 executes the process shown in FIG. 7, and when a connection request to the first network 10 is given from the user, the mobile radio terminal apparatus 100 does not store the subscriber identification information SID, so A connection process to the wireless LAN is executed. Thereby, data as shown in FIG. 8 is transmitted to the radio base station 200 (S900).

  On the other hand, in the radio base station 200, the data is received through the radio communication unit 201, the data is analyzed by the control unit 210, and the mobile radio terminal device 100 transmits the subscriber identification information SID via the second network 20. Recognize that the process is to acquire. Accordingly, in the radio base station 200, the control unit 210 controls the radio communication unit 201 to connect the mobile radio terminal apparatus 100 to the second network 20 (user ID (radio network identification information PID)). And request to transmit the password (S901).

  On the other hand, in the mobile radio terminal apparatus 100, when the second communication unit 102 receives a radio signal from the radio base station 200 and the control unit 110 detects the request from the signal processing result of the signal processing unit 103, the control unit 110 110 reads out the wireless network identification information PID and password from the storage unit 104, and transmits them to the wireless base station 200 by controlling the signal processing unit 103 and the second communication unit 102 (S902).

  In contrast, the radio base station 200 receives the radio network identification information PID and password through the radio communication unit 201. Then, the control unit 210 controls the network communication unit 202, and based on the address information 801 included in the data acquired in S900, the database station 300 is the destination, and the individual identification information TID 802 included in the data acquired in S900 Then, the identification information 803 of the first network 10 and the wireless network identification information PID and password acquired in S902 are transmitted (S903).

  On the other hand, in the database station 300, the network communication unit 301 receives the information transmitted by the radio base station 200 in S903. The control unit 310 refers to the information stored in the storage unit 302 and confirms whether the correspondence between the received wireless network identification information PID and the password is valid.

  When it is confirmed that the control unit 310 is valid, the control unit 310 refers to the information stored in the storage unit 302 and detects the subscriber identification information SID associated with the received wireless network identification information PID. Here, when a plurality of subscriber identification information SIDs are associated with the wireless network identification information PID and stored in the storage unit 302, the subscription corresponding to the first network 10 is based on the received identification information 803. The person identification information SID is detected. Then, the control unit 310 controls the network communication unit 301 to transmit the detected subscriber identification information SID to the radio base station 200 (S904).

  On the other hand, the radio base station 200 receives the subscriber identification information SID through the network communication unit 202. Then, the control unit 210 controls the network communication unit 202 to address the first network 10 based on the identification information 803 included in the data acquired in S900 and the individual identification information TID 802 included in the data acquired in S900. The subscriber identification information SID and the location information 804 included in the data acquired in S900 are transmitted in association with each other (S905). As a result, the individual identification information TID 802, the subscriber identification information SID, and the location information 804 are transmitted to the first network 10 via the public network 30.

  On the other hand, the control station 400 receives the individual identification information TID 802, the subscriber identification information SID, and the position information 804 through the network communication unit 401. Then, the control unit 410 stores the received individual identification information TID 802 and subscriber identification information SID in the storage unit 402.

  Then, after performing the above storage, the control unit 410 refers to the information stored in the storage unit 402 and detects that the nearest radio base station is the radio base station 500 based on the received position information 804. . Then, the control unit 410 associates the identification information of the radio base station 500 with the received individual identification information TID 802 and the subscriber identification information SID as location registration information, and records them in the storage unit 402.

  The control unit 410 also controls the network communication unit 401 to issue a connection request from the mobile radio terminal apparatus 100 corresponding to the individual identification information TID 802 and the subscriber identification information SID in the radio zone to the radio base station 500. An instruction is given to wait (S906).

  On the other hand, in the radio base station 500, when the network communication unit 502 receives the instruction, the control unit 510 controls the radio communication unit 501, and waits for reception of a connection request from the mobile radio terminal device 100. When the preparation is completed, the network communication unit 502 is controlled to notify the control station 400 that the preparation is completed (S907). Along with the notification, control unit 510 starts a timer.

  On the other hand, when the control station 400 receives a notification of completion of preparation from the radio base station 500 through the network communication unit 401, the control unit 410 notifies the radio base station 200 through the network communication unit 401 of a registration completion notification ( Connection permission notification) is performed (S908).

  On the other hand, in the wireless base station 200, when the network communication unit 202 receives the registration completion notification, the control unit 210 controls the wireless communication unit 201, and the subscriber identification information SID received in S904 is transmitted to the mobile wireless terminal device. 100 (S909).

  On the other hand, in the mobile radio terminal apparatus 100, when the second communication unit 102 receives the subscriber identification information SID (steps 7g and 7h), the control unit 110 controls the first communication unit 101, and The received subscriber identification information SID and the individual identification information TID stored in the storage unit 104 are transmitted to the radio base station 500 to make a connection request (S910, step 7c).

  On the other hand, in the radio base station 500, when the radio communication unit 501 receives the connection request, the control unit 510 waits for the subscriber identification information SID and the individual identification information TID included in the received connection request from S907. Make sure it matches what you had.

  When this confirmation is made and the time counted by the timer started in S907 is within a preset time, the control unit 510 controls the wireless communication unit 501 to communicate with the mobile wireless terminal device 100, The mobile radio terminal device 100 is connected to the first network 10. If the time counted by the timer activated in S907 exceeds a preset time, the subscriber identification information SID and individual identification information TID acquired in S906 are deleted.

  As described above, in the mobile communication system configured as described above, subscriber identification information necessary for using the first network 10 when the mobile radio terminal apparatus 100 accepts a connection request to the first network 10 from the user. If the SID is not stored, it connects to the second network 20 and requests the subscriber identification information SID.

  On the other hand, the second network 20 determines whether or not the mobile wireless terminal device 100 is a legitimate user from the individual identification information TID and the like, and if it is a legitimate user, The subscriber identification information SID is acquired from the first network 10 and notified to the mobile radio terminal apparatus 100. The mobile radio terminal apparatus 100 that has received this notification is connected to the first network 10 using the notified subscriber identification information SID.

  That is, according to the mobile communication system configured as described above, even when the mobile radio terminal apparatus 100 does not store the subscriber identification information SID, the mobile radio terminal apparatus 100 is authenticated by the second network 20 and the first network 10 From the public network 30 and the second network 20, the subscriber identification information SID can be acquired. Therefore, the mobile radio terminal apparatus 100 can be connected to the first network 10 without detaching the storage module for storing the subscriber identification information SID, and is highly convenient.

  When the mobile radio terminal apparatus 100 can be connected to a network other than the first network 10 and the second network 20, the second network 20 uses the individual identification information of the mobile radio terminal apparatus 100 as described in S904. The subscriber identification information SID for each network is associated with the TID 802 and stored in the storage unit 302, and the subscriber identification information SID corresponding to the network specified by the identification information 803 from the mobile radio terminal device 100 is stored in the network. To transmit the mobile radio terminal apparatus 100.

  Therefore, according to the mobile communication system having the above configuration, the subscriber identification information SID can be acquired through the second network 20 even for a network other than the first network 10.

  In addition, the control station 300 stores one piece of subscriber identification information SID in association with a plurality of individual identification information TID 802, and judges the validity of the mobile radio terminal apparatus 100 based on this information. May be. According to this, even when a plurality of mobile radio terminal devices are selectively used with one subscriber identification information SID, it is not necessary to attach / detach the storage module for storing the subscriber identification information SID from the mobile radio terminal device, thereby improving convenience. To do.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiment is also conceivable. Furthermore, you may combine suitably the component described in different embodiment.

  As an example, for example, in the above embodiment, the control station 400 detects the nearest radio base station 500 from the received position information 804 in S906, and sends a connection request from the mobile radio terminal apparatus 100 to this radio base station. Instructed to wait. Instead, for example, the control station 400 estimates the radio base station 500 that forms the radio zone to which the mobile radio terminal apparatus 100 belongs based on the received position information 804 and moves to the estimated radio base station 500. It may be instructed to wait for a connection request from the wireless terminal device 100. Further, not only one radio base station but also a plurality of radio base stations may be instructed to wait for a connection request.

  Further, as shown in FIG. 10, subscriber information management means 104 c may be provided in the storage unit 104. This subscriber information management means 104c limits the use of the subscriber identification information SID stored in the subscriber identification storage means 104b according to, for example, the service.

  The mobile radio terminal apparatus 100 obtains the subscriber identification information SID from the second network 20 and stores it in the subscriber identification storage means 104b by the processing shown in FIGS. If the service cannot be provided to the user, the connection to the first network 10 is not performed.

  A case where the service cannot be provided is a case where there are restrictions (connection time, connection time, number of connections) in using the service. As an example of a specific realization method, restriction information indicating restriction is stored in the storage unit 104, and even when the subscriber identification information SID is acquired from the second network 20, the restriction information stored in the storage unit 104 is stored. In the case where indicates a use restriction, connection to the first network 10 or service request is not performed.

  Furthermore, in the above embodiment, the mobile radio terminal device 100 detects the position information at the GPS receiver 106 and transmits this information to the first network 10 through the second network 20 and the public network 30. Instead of this, for example, the mobile radio terminal apparatus 100 receives information uniquely transmitted by the radio base station 500 and transmits it to the first network 10 through the second network 20 and the public network 30 as position information. May be.
