Description

  The present invention relates to a mobile communication terminal usage restriction method and a mobile communication system, and more particularly to a stolen mobile communication terminal use restriction method and a mobile communication system.

  In recent years, theft of mobile phones has been increasing. The reason why cell phone thefts are increasing is that the functions of cell phones have become highly functional and the cell phones have become more expensive, and cell phones obtained through theft can now be sold at high prices. .

  By the way, at present, a mobile communication carrier registers a SIM card number, which is subscriber identification information, in a subscriber identity card (SIM card), which is an IC card, for a subscriber of a cellular phone. This SIM card is distributed. A mobile phone contractor has a system in which the SIM card is mounted on a mobile phone that is freely selected and purchased by the contractor and receives a service from a mobile communication carrier. This has the advantage that the cellular phone subscriber can freely change the cellular phone at any time by replacing the SIM card with the cellular phone. On the other hand, there has been a problem that mobile phones that have been stolen can be used normally.

  The adoption of the SIM card method is an epoch-making idea in that the mobile phone can be freely changed as compared with the second generation mobile phone that has not been adopted. However, in the second-generation mobile phone in which information equivalent to the information stored in the SIM card is directly stored in the mobile phone without using the SIM card method, a large number of new mobile phones are available in mobile phone shops. I was never stolen. This is because the mobile phone shop stores the same information as the information stored in the SIM card immediately before handing over the sold mobile phone to the customer, so even if the mobile phone is stolen from the mobile phone shop. This is because information equivalent to the information stored in the SIM card is not stored in the mobile phone and cannot be used.

  However, since the SIM card system is currently adopted as described above, as long as you have a SIM card registered with a mobile communication carrier, you can make a call regardless of what mobile phone the SIM card is installed in. What becomes possible is the biggest problem of mobile phone theft. With this mechanism, a large number of mobile phones are stolen at a time in mobile phone shops that handle mobile phones, and the mobile phones are freely used.

  Therefore, Patent Document 1 registers a set of a mobile phone identification number and an address stored in a SIM card (USIM card) attached to the mobile phone in the database of the customer management system when the mobile phone is contracted. When the mobile phone is stolen or lost, the mobile phone subscriber requests the communication carrier to perform a security process, so that the carrier can use the address and terminal identification number in the above set. After confirming that the device exists, a security ensuring process is performed on another set of mobile phones having the same address as that in the above set and a terminal identification number different from the above set terminal identification number. A method of ensuring safety has been proposed.

  Further, Patent Document 2 discloses a case where authentication is performed using known subscriber information in a SIM card managed by a telephone carrier and a terminal identification number unique to a mobile phone, and both authentications match. Only discloses a terminal authentication method that permits the use of the mobile phone.

  Further, in Patent Document 3, setting information registered in association with a telephone number set in a SIM card inserted into a mobile phone when it is determined that the pairing between the SIM card and the mobile phone has changed is stored in a database. There has been proposed a mobile communication terminal that reads data from.

JP 2007-201883 A Japanese Patent Laid-Open No. 2007-281861 JP 2008-206061 A

  However, in the security ensuring method described in Patent Document 1, when a set of an identification number of a mobile phone and an address stored in the SIM card exists, a message addressed to the address is transmitted to the mobile phone of the existing set. This is not intended to reduce theft of the mobile phone by performing a process of disabling the stolen or lost mobile phone.

  Further, the terminal authentication method described in Patent Document 2 is a method that makes it impossible to use a mobile phone other than a contract operator (specific communication carrier). Use cannot be prohibited.

  Further, Patent Document 3 discloses a configuration in which when a SIM card mounted on a mobile phone is changed to another SIM card, information on the SIM card before the change is moved to the SIM card after the change. However, there is no description of a configuration that prevents unauthorized use of a stolen or lost mobile phone.

  The present invention has been made in view of the above points, and reduces theft of a mobile phone by making it impossible to use a mobile phone obtained illegally by theft even if another subscriber identification card is mounted. It is an object of the present invention to provide a mobile communication terminal usage restriction method and a mobile communication system capable of performing the above.

  In order to achieve the above object, a method for restricting the use of a mobile communication terminal according to the present invention includes a first terminal identification number unique to a first mobile communication terminal that is properly purchased and to which a subscriber identification card is removable. A registration step of registering the first subscriber identification information stored in the installed first subscriber identification card in association with the storage means indicating that they are related to each other, and a subscription at the start of use A second terminal identification number unique to the second mobile communication terminal and a second stored in the second subscriber identification card installed from the second mobile communication terminal to which the user identification card is detachable. A transmitting step for transmitting the subscriber identification information, a receiving step for receiving the second terminal identification number and the second subscriber identification information transmitted in the transmitting step, and a second received in the receiving step. Terminal identification number and second subscriber identification The second terminal identification number and the second subscriber identification information are registered in the storage means by comparing and determining whether the information is registered in association with the storage means and the comparison determination step. Only when the comparison result of the first terminal identification number and the first subscriber identification information being matched and registered with each other is obtained, the second mobile communication terminal And a permission step for permitting use in a mobile communication network.

  In order to achieve the above object, the mobile communication system of the present invention is stored in a unique first terminal identification number assigned in advance before use and a first subscriber identification card installed. A mobile communication terminal that transmits the first subscriber identification information, a second terminal identification number unique to the mobile communication terminal that has been properly purchased, and a second subscription to be implemented in the mobile communication terminal Registration means for preliminarily registering the second subscriber identification information stored in the user identification card with the storage means in association with each other indicating that they are related to each other, the first terminal identification number, and the first A receiving means for receiving subscriber identification information, a second terminal identification in which the first terminal identification number and the first subscriber identification information received by the receiving means are registered in advance in association with the storage means. The number and whether it is the second subscriber identification information When a comparison determination result in which the received first terminal identification number and the first subscriber identification information are registered in association with the storage unit is obtained by the comparison determination unit and the comparison determination unit. And a permission means for permitting use of the mobile communication terminal in the mobile communication network.

  According to the present invention, it is possible to reduce theft of the mobile phone by making it impossible to use it even if another subscriber identification card is mounted on the mobile phone obtained illegally by theft. Further, according to the present invention, it is possible to specify the user (criminal) of the cellular phone who has been stolen.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 shows a configuration diagram of a mobile communication system to which a first embodiment of a mobile communication terminal use restriction method according to the present invention is applied. The mobile communication system shown in FIG. 1 includes a home location register (hereinafter, HLR) 11, an exchange (including a radio network controller (RNC)) 12, a base station 13, and a mobile phone 14 as an example of the mobile communication system. .

  The HLR 11 stores a location registration signal and, as shown in FIG. 2, a telephone number 111 that is a unique terminal identification number of a mobile phone, a card number (hereinafter referred to as a SIM card number) 112 of a SIM card, and these telephones The association information indicating that the number 111 and the SIM card number 112 are related is stored. Also, the HLR 11 compares the telephone number and SIM card number transmitted from the mobile phone 14 with the telephone number registered in the HLR 11 and the SIM card number, and these are registered in association with the HLR 11. If any of them is not registered, or if they are registered but not registered for linking, the connection of the mobile phone 14 to the mobile communication network is rejected (mobile communication network). Not allowed to use in).

  The exchange 12 is connected to several tens of base stations (in FIG. 1, for convenience of illustration, one of the base stations 13 is shown as a representative), and controls the base station 13 to manage radio resources. Do. Further, the exchange 12 receives from the mobile phone 14 communicating with each base station, via the base station 13, a location registration signal that is information indicating in which base station the mobile phone 14 is located. A location registration signal is transmitted to the HLR 11 and stored.

  As shown in FIG. 3, the mobile phone 14 has a telephone number 141 and a SIM card number 142 registered therein. The telephone number 141 is a unique number assigned to the mobile phone 14 and is directly stored in the mobile phone 14. Further, the SIM card number 142 is stored in an IC card that is detachable from the mobile phone 14 called a SIM card. FIG. 3 shows a state when the SIM card is mounted on the mobile phone 14.

  Next, the operation of this embodiment will be described. First, a process until a mobile phone is purchased and used normally will be described with reference to FIGS.

  When the mobile phone 14 is purchased at a mobile phone shop (step S1 in FIG. 4), the mobile phone shop sells the phone number of the mobile phone 14 and the SIM card number of the SIM card to be installed in the mobile phone 14. Is communicated to the mobile communication carrier that manages the mobile communication network (step S2 in FIG. 4). Then, the mobile communication carrier registers the telephone number and the SIM card number that have been contacted in the HLR 11 as indicated by 111 and 112 in FIG. 2, and further, the telephone number 111 and the SIM card number 112 Is also associated (in step S3 in FIG. 4).

  After the registration is completed, when the SIM card linked and registered with the HLR 11 at the time of purchase is mounted on the purchased mobile phone 14 and the mobile phone 14 is turned on, the mobile phone 14 stores the information as shown in FIG. And the SIM card number 142 of the installed SIM card are transmitted (step S4 in FIG. 4). The transmitted telephone number 141 and SIM card number 142 reach the HLR 11 via the base station 13 and the exchange 12.

  The mobile communication service provider matches the telephone number 111 and the SIM card number 112 registered in the HLR 11 with the telephone number 141 and the SIM card number 142 transmitted from the mobile phone 14 input from the exchange 12, respectively. And the registration status of whether or not they are linked is confirmed (step S5 in FIG. 4). The mobile communication carrier uses the regular mobile phone 14 when the phone number 111 and the SIM card number 112 respectively matching the phone number 141 and the SIM card number 142 are registered in association with the HLR 11. And the normal operation that can be used in the mobile communication network is made (step S6 in FIG. 4), and in other cases, the use in the mobile communication network is not permitted (step in FIG. 4). S7).

  Next, the above operation will be described more specifically. It is assumed that the SIM card number 142 of the SIM card to be mounted on the purchased mobile phone 14 is “AAA” as shown in FIG. 5, and the phone number 141 of the purchased mobile phone 14 is “100”. The telephone number “100” and the SIM card number “AAA” are communicated to the mobile communication carrier from a shop that handles mobile phones.

  As a result, the mobile communication operator registers “100” as the telephone number 111 and “AAA” as the SIM card number 112 in the HLR 11 as shown in FIG. That is, in the HLR 11, the telephone number 111 “100” and the SIM card number 112 “AAA” are linked.

  Thereafter, when “AAA” is transmitted as the SIM card number 122 together with the telephone number “100” from the mobile phone 14 in which the telephone number “100” is registered, the mobile communication carrier is registered in the HLR 11. Since there is “100” in the telephone number 111 and “AAA” in the registered SIM card number 112 and they are registered in association with each other, it is possible to use the regular mobile phone 14. It is judged that there is, and the use in the mobile communication network is permitted. On the other hand, when the mobile communication carrier transmits a SIM card number other than “AAA” as the SIM card number 122 together with the telephone number “100” from the mobile phone 14 in which the telephone number “100” is registered. , There is “100” in the telephone number 111 registered in the HLR 11, but the SIM card number 112 registered in association with the telephone number 111 is not “AAA”. The use of the mobile phone 14 in the mobile communication network is not permitted.

  Next, a description will be given of the process until the mobile communication carrier obtains the mobile phone 14 from a shop other than the mobile phone handling shop such as taking over the mobile phone 14 from an acquaintance and can use it normally. Moreover, the case where it cannot be used is also demonstrated.

  As shown in FIG. 5, the mobile phone 14 before handing over has a telephone number 141 of “100”, and a SIM card number 142 of the SIM card to be mounted is “AAA”. When handing over the mobile phone 14, the SIM card is naturally different from the registered one, and the SIM card number 142 is other than “AAA”. Here, even if the SIM card with the SIM card number “BBB” is mounted on the mobile phone 14 with the telephone number “100”, the operation of the present embodiment enables the use within the mobile communication network. This will be described with reference to the flowchart of FIG. 6 and FIGS.

  The mobile phone 14 having the telephone number “100” is mounted with the SIM card having the SIM card number “AAA” to be usable in the mobile communication network (step S11 in FIG. 6). “BBB” is transmitted to the mobile communication carrier as schematically shown at 21 in FIG. 7 (step S12 in FIG. 6). As a result, the mobile communication carrier adds an additional “BBB” in the HLR 11 in addition to the SIM card number “AAA” registered in association with the telephone number “100” as indicated by 22 in FIG. Add registration (step S13 in FIG. 6).

  Next, after turning off the power of the mobile phone 14 (step S14 in FIG. 6), the SIM card with the SIM card number “AAA” that has been mounted on the mobile phone 14 is removed, and the SIM card number “BBB” is removed. A new SIM card is mounted (exchanged) (step S15 in FIG. 6). In this state, when the power of the mobile phone 14 is turned on (when the power is turned on), “BBB” is set as the SIM card number 122 together with the phone number “100” from the mobile phone 14 in which the phone number “100” is automatically registered. It is transmitted to the mobile communication carrier (step S16 in FIG. 6).

  Then, the mobile communication carrier determines whether the telephone number “100” and the SIM card number “BBB” transmitted from the mobile phone 14 in which the telephone number “100” is registered are registered in association with the HLR 11. 8 is compared and confirmed as schematically shown at 24 (step S17 in FIG. 6). Here, as shown in FIG. 8, in the HLR 11, there is “100” in the telephone number 111, and “BBB” in the registered SIM card number 112, and they are registered in association with each other. Therefore, it is determined that the mobile phone 14 is being used normally, and its use in the mobile communication network is permitted (step S18 in FIG. 6).

  Here, even if the cellular phone 14 is turned on with the combination of the telephone number 141 and the SIM card number 142 that are not associated with the HLR 11 and the association registration is confirmed, the association is registered with the HLR 11. Accordingly, the mobile communication carrier does not permit the use of the mobile phone 14 in the mobile communication network (step S19 in FIG. 6).

  For example, as shown by 22 in FIG. 9, when the SIM card numbers associated with the telephone number “100” in the HLR 11 are “AAA” and “BBB”, the mobile communication carrier When the SIM card number transmitted together with the telephone number “100” from 14 is “ZZZ” as indicated by 25 in FIG. 9, the transmitted telephone number “100” and the SIM card number “ZZZ”. However, since it is not registered in the HLR 11 as shown schematically in FIG. 9 whether the registration is associated with the HLR 11, the mobile communication carrier Use in mobile communication networks is not permitted.

  As described above, according to the present embodiment, the mobile phone 14 is mounted on the mobile phone 14 with the unique telephone number of the mobile phone 14 in the mobile communication network (HLR 11 in this embodiment) managed by the mobile communication carrier. Since the SIM card number of the SIM card is registered and registered, the mobile phone can be used when the SIM card number is not registered in the HLR 11 just by mounting the SIM card on the mobile phone. Can not. For this reason, since the mobile phone cannot be used even if it is illegally obtained by theft and another SIM card is mounted, the theft of the mobile phone can be reduced.

  Further, according to the present embodiment, there is a possibility that the user (criminal) of the cellular phone who has been stolen can be identified. The reason for this is that, as shown in FIG. 9, when a SIM card having a SIM card number that is not registered with a telephone number in the HLR 11 is mounted on an illegally obtained mobile phone and the mobile phone is turned on, The mobile phone operator is notified of the mobile phone number and SIM card number, and whether or not they are registered in the HLR 11 for comparison, and is not registered for registration. Use in the telecommunications network is not permitted. At this time, since the telephone number and SIM card number of the mobile phone obtained illegally are received as a set in the HLR 11, the owner of the SIM card can be specified from the received SIM card number. (Criminal) may be identified. Further, since the HLR 11 also has location information of the mobile phone, the location of the mobile phone can also be specified.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. FIG. 10 shows a configuration diagram of a mobile communication system to which the second embodiment of the mobile communication terminal use restriction method according to the present invention is applied. In the figure, the same components as those in FIG.

  The second embodiment shown in FIG. 10 has a configuration in which a management server 15 is added to the first embodiment shown in FIG. In the present embodiment, the management server 15 performs the registration of the combination of the telephone number of the mobile phone 14 and the SIM card and the use / non-use of the mobile phone 14, which were performed in the HLR 11 in the first embodiment. It is a thing. Thereby, this embodiment also has the same features as the first embodiment.

  The present invention is not limited to the above embodiment. For example, the mobile communication terminal is not limited to a mobile phone, but is also a PHS (Personal Handyphone System), PDA (Personal Data Assistance, Personal Digital Assistants). Type information communication equipment).
