About.

  BACKGROUND Conventionally, as a technology related to mobile communication, an embedded universal integrated circuit card (eUICC) (also called an embedded subscriber identity module (eSIM)) is known (see, for example, Patent Document 1). The eUICC is a subscriber authentication module storing a profile, which is subscriber information necessary for the mobile communication terminal to perform mobile communication in a mobile communication network, and is usually incorporated in the mobile communication terminal. The mobile communication terminal can download a new profile and store it in the eUICC, thereby changing the mobile communication network (communication carrier) capable of performing mobile communication.

JP, 2014-192535, A

  When the profile is downloaded to the eUICC, the profile is encrypted between the server holding the profile and the eUICC. Therefore, the mobile communication terminal in which the eUICC is incorporated can not grasp the contents of the profile until the use of the profile decoded by the eUICC is started.

  The frequency band and communication system of the mobile communication network differ depending on the telecommunications carrier or the like who provides the mobile communication network. On the other hand, also in the mobile communication terminal, the communicable frequency band and communication system differ for each mobile communication terminal. Therefore, usually, the mobile communication terminal performs mobile communication by mounting the UICC which is a subscriber authentication module storing the profile corresponding to the communicable mobile communication network.

  However, when the profile corresponding to the mobile communication network which the mobile communication terminal can not communicate is downloaded to the eUICC, the mobile communication terminal can not perform mobile communication. Since the eUICC is incorporated in the mobile communication terminal, in this case, mobile communication can not be performed unless the eUICC downloads another profile by means other than mobile communication. If there is no means other than mobile communication to download another profile, the mobile communication terminal becomes unusable.

  The present invention is made in view of the above, and a subscriber information control apparatus and subscriber information control system capable of preventing subscriber information which can not be communicated by a mobile communication terminal from being stored in a subscriber authentication module.

In the description of the drawings, the same elements will be denoted by the same reference symbols, without redundant description.

First Embodiment
FIG. 1 shows a mobile communication terminal 10 which is a subscriber information control apparatus according to the first embodiment. The mobile communication terminal 10 is a device that performs mobile communication in the communication carrier network 20 that is a mobile communication network (connected to the communication carrier network 20). The mobile communication terminal 10 is provided with an eUICC 11, which is a subscriber authentication module. The eUICC 11 stores a profile (UICC software) which is subscriber information which is information necessary for the mobile communication terminal 10 to perform mobile communication in the carrier network 20. The profile includes, for example, a telephone number or International Mobile Subscriber Identity (IMSI), which is contract information provided by a carrier.

  A plurality of telecommunications carrier networks 20 exist for each telecommunications carrier. The profile corresponds to the telecommunications carrier network 20 (a telecommunications carrier). The mobile communication terminal 10 can perform mobile communication in the carrier network 20 corresponding to the profile stored in the eUICC 11. The profile stored in the eUICC 11 is rewritable, and by rewriting the profile, it is possible to change the telecommunications carrier network 20 (a telecommunications carrier) in which the mobile communication terminal 10 can perform mobile communication.

  Unlike the UICC, the eUICC 11 is usually fixedly incorporated in the mobile communication terminal 10. Therefore, the mobile communication terminal 10 is often used as a device that can not or can not easily exchange UICCs, or is incorporated in such a device. For example, the mobile communication terminal 10 is used as an apparatus for performing M2M (machine-to-machine) communication or incorporated in such an apparatus. However, in the present invention, the subscriber authentication module may be detachably attached to the mobile communication terminal 10 as with the UICC.

  The mobile communication terminal 10 downloads the profile from the eUICC server 30, and installs (stores) the profile in the eUICC 11. The eUICC server 30 is a server that provides the mobile communication terminal 10 with a profile. The eUICC server 30 is provided by, for example, a communication carrier. As shown in FIG. 1, one eUICC server 30 may provide the mobile communication terminal 10 with profiles corresponding to a plurality of carrier networks 20. The mobile communication terminal 10 and the eUICC server 30 can mutually transmit and receive information via the carrier network 20 or a wireless LAN (local area network) or the like. The mobile communication terminal 10 and the eUICC server 30 may transmit and receive information to each other by near field communication.

  Subsequently, functions of the mobile communication terminal 10 according to the present embodiment will be described. As shown in FIG. 1, the mobile communication terminal 10 includes an eUICC 11, a mobile communication unit 12, a network information acquisition unit 13, a terminal information acquisition unit 14, a determination unit 15, and a control unit 16. It is done. The functional units 12 to 16 other than the eUICC 11 are the functions of the mobile communication terminal 10 itself (not the functions in the eUICC 11). Moreover, the mobile communication terminal 10 may be equipped with the function with which the conventional mobile communication terminal is provided besides the above.

  The eUICC 11 is a subscriber authentication module that stores a profile as described above. The eUICC 11 may have the same configuration as the conventional eUICC. Specifically, the eUICC 11 functions by operating an eUICC OS (Operating System) stored in the eUICC 11. Further, the eUICC 11 is provided with an area in which a profile is stored.

  The mobile communication unit 12 is means for performing mobile communication. The mobile communication unit 12 performs mobile communication using the profile stored in the eUICC 11. The function of the mobile communication unit 12 may be the same as the mobile communication function of the conventional mobile communication terminal.

  The network information acquisition unit 13 is network information acquisition means for acquiring network information indicating functions required to perform mobile communication in the communication carrier network 20 corresponding to the profile. This profile is to be newly stored (candidate) in the eUICC 11. The network information acquisition unit 13 acquires network information as information different from the profile itself. The network information is prepared in advance by the provider of the profile (for example, by each carrier). For example, the eUICC server 30 stores network information in association with a profile in advance, and transmits the profile and the network information to the mobile communication terminal 10 in response to a profile request from the mobile communication terminal 10.

  For example, the network information acquisition unit 13 transmits a profile request to the eUICC server 30, and receives (downloads) the profile itself transmitted from the eUICC server 30 in response to the profile request and the network information corresponding to the profile. To get. The profile request includes information identifying the profile to be acquired. Also, transmission of the profile request is triggered by, for example, the user's operation of storing a new profile in the eUICC 11 with respect to the mobile communication terminal 10. The network information acquisition unit 13 outputs the acquired profile and network information to the determination unit 15.

  The profile transmitted from the eUICC server 30 is encrypted (hidden), and the mobile communication terminal 10 can not grasp the contents of the profile until it is decrypted in the eUICC. The network information is provided as plaintext information different from the profile itself so that the content can be grasped regardless of the profile encrypted in the mobile communication terminal 10.

  Specifically, the network information includes information indicating at least one of a frequency, a communication method, and a communication type related to mobile communication performed by using a profile associated with the network information. Specifically, the information indicating the frequency is information indicating the frequency band of the radio wave for performing the mobile communication. The information indicating the communication method is information indicating a method (may be a more detailed method) of the communication carrier network 20 such as 3G or 4G. The information indicating the communication type is information indicating whether the communication carrier network 20 is a network for voice terminals or a network for data terminals.

  The network information acquisition unit 13 may acquire connection destination information indicating an APN (access point name) which is a connection destination in the communication carrier network 20 corresponding to the profile, in addition to the acquisition of the profile. In this case, the network information acquisition unit 13 functions as a control unit that causes the own terminal 10 to acquire connection destination information (acquires connection destination information in the own terminal 10). Similar to the network information, the connection destination information is prepared in advance by the provider of the profile (for example, by each communication carrier). For example, the eUICC server 30 stores network information in association with a profile in advance, and in accordance with the profile request from the mobile communication terminal 10, the connection destination information is added to the mobile communication terminal 10 together with the profile and the network information. Send. The connection destination information may be plaintext information as well as the network information. When the network information acquisition unit 13 acquires connection destination information, the network information acquisition unit 13 associates the acquired connection destination information with the profile and outputs the same (the same applies to the subsequent function units).

  The connection destination information may include, besides the APN, information related to settings used when the mobile communication terminal 10 performs mobile communication in the communication carrier network 20 corresponding to the profile. For example, a shortcut of an application (service application) used when performing mobile communication in the communication carrier network 20 may be included.

  The terminal information acquisition unit 14 is a terminal information acquisition unit that acquires terminal information indicating a function related to mobile communication that the own terminal 10 has. For example, the terminal information is stored in advance in the mobile communication terminal 10, for example, by the provider of the mobile communication terminal 10. The terminal information acquisition unit 14 reads out and acquires terminal information stored in the own terminal 10. Acquisition of terminal information is performed when acquisition of network information by the network information acquisition unit 13 is performed. The terminal information acquisition unit 14 outputs the acquired terminal information to the determination unit 15.

  Terminal information specifically includes information corresponding to network information. That is, the terminal information includes information indicating at least one of a frequency related to mobile communication, a communication method, and a communication type. The information indicating the frequency is, specifically, information indicating the frequency band of the radio wave of the mobile communication to which the own terminal 10 is compatible. The information which shows a communication method is information which shows the system of the communication carrier network 20 which the own terminal 10 respond | corresponds. The information indicating the communication type is information indicating whether the own terminal 10 is a voice terminal or a data terminal.

  The determination unit 15 compares the network information input from the network information acquisition unit 13 with the terminal information input from the terminal information acquisition unit 14, and the own terminal 10 is provided with a profile corresponding to the network information. It is a determination unit that determines whether or not to store in the eUICC 11. From the network information and the terminal information, the determination unit 15 determines whether mobile communication can be performed in the communication carrier network 20 corresponding to the network information (profile). That is, the determination unit 15 confirms the compatibility of the profile.

  The determination unit 15 determines whether the function of the own terminal 10 indicated by the terminal information satisfies the function necessary to perform mobile communication indicated by the network information. For example, as to the frequency, it is determined whether the band supported by the own terminal 10 indicated by the terminal information includes the band of the carrier network 20 indicated by the network information. If it is determined that the band supported by the own terminal 10 includes the band of the telecommunications carrier network 20, it is determined that the function of the own terminal 10 satisfies the function necessary for performing mobile communication.

  As for the communication method, it is determined whether or not the method supported by the own terminal 10 indicated by the terminal information is the method of the telecommunications carrier network 20 indicated by the network information. If it is determined that the method supported by the own terminal 10 is the method of the telecommunications carrier network 20, it is determined that the function of the own terminal 10 satisfies the function necessary for performing mobile communication. As for the communication type, it is determined whether the type of the own terminal 10 indicated by the terminal information matches the type of the telecommunications carrier network 20 indicated by the network information. If it is determined that the type of the own terminal 10 is the type of the telecommunications carrier network 20, it is determined that the function of the own terminal 10 satisfies the function necessary for performing mobile communication.

  When the network information includes information on a plurality of items, the function of the own terminal 10 indicated by the terminal information performs mobile communication indicated by the network information when it is determined that the above condition is satisfied for all the items. It is judged that the necessary functions are satisfied. That is, when it is determined that any item is not satisfied, it is determined that the function of the own terminal 10 indicated by the terminal information does not satisfy the function necessary for performing mobile communication indicated by the network information.

  When determining that the function of the own terminal 10 satisfies the function necessary for mobile communication, the determination unit 15 determines that the eUICC 11 provided in the own terminal 10 stores the profile corresponding to the network information. When determining that the function of the own terminal 10 does not satisfy the function necessary to perform mobile communication, the determining unit 15 determines that the eUICC 11 provided in the own terminal 10 does not store the profile corresponding to the network information. . The determination unit 15 outputs the information indicating the determination result and the profile to the control unit 16.

  The control unit 16 is a control unit that performs control to store the profile corresponding to the network information in the eUICC 11 provided in the own terminal 10 according to the determination by the determination unit 15. When it is determined by the determination unit 15 that the profile is stored in the eUICC 11, the control unit 16 inputs the profile into the eUICC 11 and stores (installs) the profile. The process of installing the profile in the eUICC 11 and the process of starting mobile communication between the mobile communication terminal 10 and the carrier network 20 corresponding to the profile may be the same as in the prior art. Specifically, those processes will be described in the description of the flow.

  When connection destination information is associated with the profile, the control unit 16 sets an APN indicated by the connection destination information as a connection destination in the communication carrier network 20 together with the installation of the profile. If the connection destination information further includes information related to settings other than the APN, the control unit 16 performs setting based on the information.

  When it is determined by the determination unit 15 that the profile is not stored in the eUICC 11, the control unit 16 does not install the profile (in the terminal 10, mobile communication can not be performed in the carrier network 20 corresponding to the profile) Notify This notification is performed, for example, by displaying the notification on a display device provided in the mobile communication terminal 10. Further, the control unit 16 deletes the profile input from the determination unit 15. The above is the function of the mobile communication terminal 10 according to the present embodiment.

  FIG. 2 shows the hardware configuration of the mobile communication terminal 10 according to the present embodiment. As shown in FIG. 2, the mobile communication terminal 10 includes a central processing unit (CPU) 101, a random access memory (RAM) 102 as a main storage device and a read only memory (ROM) 103, an operation module 104, a wireless communication module 105. It is comprised by hardwares, such as the antenna 106, the display 107, the eUICC module 108 (hardware of eUICC11). The functions of the mobile communication terminal 10 described above are exhibited by the operation of these components by a program or the like. The above is the configuration of the mobile communication terminal 10 according to the present embodiment.

  Subsequently, a subscriber information control method which is a process (operation method of the mobile communication terminal 10) executed by the mobile communication terminal 10 according to the present embodiment will be described using the sequence diagram of FIG. The present process is performed, for example, with the user's operation of storing a new profile in the eUICC 11 on the mobile communication terminal 10 as a trigger. In this processing, first, a profile request is transmitted from the network information acquisition unit 13 to the eUICC server 30 (S01, network information acquisition step). The eUICC server 30 receives the profile request, and transmits a profile corresponding to the profile request to the mobile communication terminal 10. Network information and connection destination information are associated with the transmitted profile. In the mobile communication terminal 10, the network information acquisition unit 13 receives and acquires the profile (S02, network information acquisition step). The acquired profile, network information and connection destination information are output from the network information acquisition unit 13 to the determination unit 15.

  Subsequently, the terminal information acquisition unit 14 acquires terminal information (S03, terminal information acquisition step). The acquired terminal information is output from the terminal information acquisition unit 14 to the determination unit 15. Subsequently, the determination unit 15 compares the network information input from the network information acquisition unit 13 with the terminal information input from the terminal information acquisition unit 14 to obtain a profile corresponding to the network information It is determined whether or not to be stored in the provided eUICC 11 (S04, determination step). That is, the determination unit 15 checks the consistency of the profile. Information indicating the determination result and the profile are output from the determination unit 15 to the control unit 16.

  If it is determined that the profile is not stored in the eUICC 11 by the determination unit 15 (NG in S04), the profile is not installed by the control unit 16 (in the own terminal 10, mobile communication is performed in the carrier network 20 corresponding to the profile The user is notified that the user can not do it (S05). Also, the profile is deleted.

  When it is determined by the determination unit 15 that the profile is to be stored in the eUICC 11 (OK in S04), the profile is input from the control unit 16 to the eUICC 11 (S06, control step). In eUICC 11, a profile is input and installed (S07). At this time, the encrypted profile is decrypted by eUICC 11 and installed. When the installation is completed, the eUICC 11 sends a profile installation completion notification to the control unit 16 (S08).

  The control unit 16 receives the notification and then uses the connection destination information to set an APN or the like (S09, control step). Subsequently, the control unit 16 sends a profile installation completion notification to the eUICC server 30 (S10). The eUICC server 30 receives the notification and notifies the carrier network 20 corresponding to the profile of the profile (S11). In the telecommunication carrier network 20 (in the device), the notification is received, and processing for enabling mobile communication in the telecommunication carrier network 20 according to the profile (network cover of target profile) is performed (S12). When the process is completed, an Ack is transmitted from the carrier network 20 to the eUICC server 30 (S13).

  The eUICC server 30 receives the Ack. Then, Ack is transmitted from the eUICC server 30 to the mobile communication terminal 10 (S14). The mobile communication terminal 10 receives the Ack. When the Ack is received, the mobile communication terminal 10 recognizes that mobile communication in the carrier network 20 corresponding to the installed profile has become possible. Subsequently, the mobile communication unit 12 of the mobile communication terminal 10 is connected to the telecommunications carrier network 20, and mobile communication is performed (S15). The above is the processing executed by the mobile communication terminal 10 according to the present embodiment.

  As described above, according to the present embodiment, the network information and the terminal information are compared to determine whether or not the profile is to be installed in the eUICC 11, and control of the installation is performed. Therefore, according to the present embodiment, the profile can be installed in the eUICC 11 only when the mobile communication terminal 10 can communicate. That is, it is possible to prevent the profile that the mobile communication terminal 10 can not communicate from being stored in the eUICC 11. As a result, it is possible to prevent re-installing when a profile that the mobile communication terminal 10 can not communicate is installed, and to reduce the time for performing the installation.

  Also, as in the present embodiment, the network information may be information different from the profile itself. According to this configuration, for example, it is possible to acquire plaintext network information separately from the profile encrypted as described above, and even if the function of the mobile communication terminal 10 itself can not grasp the encrypted profile. The present invention can be implemented reliably and properly. Further, the network information does not have to be plaintext, as long as the network information can be grasped by the mobile communication terminal 10 even if the profile is not decrypted. For example, encryption that can be decrypted by the mobile communication terminal 10 may be performed.

  Also, the network information and the terminal information may include information indicating at least one of frequency, communication method, and communication type. According to this configuration, the effects of the present invention can be obtained appropriately and reliably. However, the network information and the terminal information are not necessarily limited to those described above, and may be anything other than the above as long as it can be determined whether the mobile communication terminal 10 can perform mobile communication in the carrier network 20. It may be

  When installing a profile as in the present embodiment, the setting of the APN or the like may be performed according to the connection destination information. Conventionally, when installing a new profile in eUICC, there has been a case where it is necessary to set an APN etc. manually. However, according to this configuration, when installing a profile, it is possible to cause the mobile communication terminal 10 to appropriately and reliably start communication without the need for manual setting. Thereby, the convenience (usability) of the user can be improved. Further, if the connection destination information is made to correspond to the contract content and the mobile communication terminal 10, the APN etc. can be made to correspond to the contract content and the mobile communication terminal 10.

  Subsequently, a modification of the present embodiment will be described. In the embodiment described above, the network information is acquired together with the profile. However, even if there is no profile, the determination by the determination unit 15 is possible. Therefore, the following configuration may be adopted. First, the network information acquisition unit 13 does not acquire a profile to be newly stored in the eUICC 11, but acquires only network information corresponding to the profile. Then, when it is determined by the determination unit 15 that the profile is stored in the eUICC 11, the control unit 16 causes the network information acquisition unit 13 to acquire the profile.

  According to this configuration, when the profile is not stored in the eUICC 11, acquisition of the profile can be prevented. This can prevent the occurrence of unnecessary communication for acquiring a profile.

  Subsequently, another modified example will be described. Although it is assumed that the connection destination information described above is plaintext information different from the encrypted profile, the connection destination information is included only in the profile because it is used only when the profile is stored in the eUICC 11. It may be That is, the connection destination information may be encrypted information included in the file configuration of the profile. For example, as connection destination information, an EF file “EF_AA” having setting information of APN, and a file “EF_BB” for notifying the mobile communication terminal 10 that the “EF_AA” is present are included in the profile. The profile file may be read after profile installation, and settings may be made.

Second Embodiment
In the first embodiment, the subscriber information control apparatus according to the present invention is the mobile communication terminal 10 provided with the eUICC 11 in which the profile is stored. However, the subscriber information control apparatus according to the present invention does not necessarily have to be the mobile communication terminal 10. In the second embodiment, an example in which the subscriber information control device according to the present invention is not the mobile communication terminal 10 is shown. That is, in the present embodiment, the mobile communication terminal 110 is configured separately from the subscriber information control device.

  FIG. 4 shows a telecommunications carrier network 120 which is a subscriber information control apparatus according to the second embodiment. The subscriber information control device is a device (for example, a server device in the core network) included in the telecommunications carrier network 120. However, in the following description, in order to make the description easy to understand, the communication business The network 120 is called the The carrier network 120 also refers to the mobile communication network itself.

  Further, in the present embodiment, the subscriber information control system 100 is configured including the carrier network 120 and the mobile communication terminal 110. The mobile communication terminal 110, the carrier network 120, and the eUICC server 130 have the mobile communication terminal 10 and the carrier network 20 described in the first embodiment except for the functions of the respective embodiments according to the present invention described below. And the same configuration as the eUICC server 30. The carrier network 120 and the mobile communication terminal 110 can mutually transmit and receive information. When the mobile communication terminal 110 does not hold the profile of the carrier network 120 (for example, when the mobile communication terminal 110 holds the profile of another carrier network 120), the mobile communication terminal 110 directly Information can not be transmitted / received to / from the carrier network 120 by mobile communication. However, the mobile communication terminal 110 transmits / receives information to / from the carrier network 120 via the wireless LAN or another carrier network 120 holding a profile. In addition, the communication carrier network 120 and the eUICC server 130 can mutually transmit and receive information via a wired network or the like.

  Subsequently, the function of the communication carrier network 120 according to the present embodiment will be described. As shown in FIG. 4, the telecommunications carrier network 120 is configured to include a terminal information acquisition unit 121, a network information acquisition unit 122, a determination unit 123, and a control unit 124. The functions of the mobile communication terminal 110 and the eUICC server 130 according to the present embodiment will also be described together with the functions of the following communication carrier network 120.

  The terminal information acquisition unit 121 is a terminal information acquisition unit that acquires terminal information indicating a function related to mobile communication that the mobile communication terminal 110 has. For example, the mobile communication terminal 110 reads out the terminal information stored in the own terminal 110, and transmits it to the communication carrier network 120 as a terminal capability notification. The terminal information is stored in advance in the mobile communication terminal 110, for example, by the provider of the mobile communication terminal 110, as in the first embodiment. The transmission of terminal information is triggered by, for example, a user's operation of storing a new profile in the eUICC 11 with respect to the mobile communication terminal 110. The carrier network 120 may be a mobile communication network corresponding to the new profile. That is, the mobile communication terminal 110 may transmit the terminal information to the carrier network 120 (of the carrier) corresponding to the new profile. The terminal information is associated with information specifying the mobile communication terminal 110 in the mobile communication terminal 110 and information specifying a new profile.

The present process is performed, for example, using a user's operation of storing a new profile in the eUICC 11 for the mobile communication terminal 110 as a trigger. In this process, terminal information of the mobile communication terminal 110 is transmitted from the mobile communication terminal 110 to the carrier network 120 as a terminal capability notification. The terminal information to be transmitted is associated with information specifying the mobile communication terminal 110 and information specifying a new profile. In the communication carrier network 120, the terminal information acquisition unit 121 receives and acquires terminal information (S101, terminal information acquisition step). The acquired terminal information is output from the terminal information acquisition unit 121 to the determination unit 123. Information for specifying a new profile associated with the acquired terminal information is output from the terminal information acquisition unit 121 to the network information acquisition unit 122.

  Subsequently, the network information acquisition unit 122 acquires network information corresponding to the new profile (S102, network information acquisition step). The acquired network information is output from the network information acquisition unit 122 to the determination unit 123. Subsequently, the determination unit 123 compares the network information input from the network information acquisition unit 122 with the terminal information input from the terminal information acquisition unit 121, and the profile corresponding to the network information is determined by the mobile communication terminal 110. It is judged whether it stores in eUICC11 with which it was prepared (S103, judgment step). That is, the determination unit 123 checks the consistency of the profile. Information indicating the determination result, information identifying the mobile communication terminal 110 associated with the network information, and information identifying a new profile are output from the determination unit 123 to the control unit 124.
