That is, the MVNO system 10, the MNO system 20, and the communication terminal 30 are communicably connected by a physical network owned by the MNO and a base station or the like. Although one MVNO system 10, one MNO system 20, and one communication terminal 30 are shown in FIG. 1, a plurality of these may exist.

  The MVNO system 10 is a system managed by the MVNO. The MVNO is a telecommunications carrier that provides mobile communication services to users by using the network and base station owned by the MNO, without owning the network and base station etc. Here, the user means an end user of the communication system 1 and means a subscriber of a telephone. For this reason, the part described as the user in this embodiment can be read as an end user or a subscriber.

  In the present embodiment, the MVNO system 10 includes a center terminal 11, a management system 12, and a network device 13. The center terminal 11, the management system 12, and the network device 13 are connected to a communication network in the MVNO.

  The center terminal 11 is a computer operated by an MVNO employee. The center terminal 11 is, for example, a personal computer or a portable information terminal (including a tablet computer) or the like, and includes a control unit, a storage unit, a communication unit, an operation unit, and a display unit.

  The control unit includes at least one microprocessor. The control unit executes processing in accordance with the program and data stored in the storage unit. The storage unit includes a main storage unit and an auxiliary storage unit. For example, the main storage unit is a volatile memory such as a RAM, and the auxiliary storage unit is a non-volatile memory such as a ROM, an EEPROM, a flash memory, or a hard disk.

The operation unit is an input device, and is, for example, a pointing device such as a touch panel or a mouse, a keyboard, or a button. The display unit is, for example, a liquid crystal display unit or an organic EL display unit.

  The management system 12 is a system that provides the mobile communication service of the MVNO, and includes at least one server computer. The server computer includes a control unit, a storage unit, and a communication unit, and their hardware configurations are the same as the control unit, the storage unit, and the communication unit of the center terminal 11, respectively.

  For example, the management system 12 includes a business support system (BSS), a home subscriber server / home location register (HSS / HLR), and a short message service center (SMSC). BSS is a business support system of MVNO. The HSS / HLR is a system for recognizing a user who permits communication, and manages various databases related to the user. SMSC is a system that controls transmission and reception of SMS (Short Message Service).

  The network device 13 is a group of network devices constituting a communication network such as an LTE (Long Term Evolution) network, and is, for example, a communication device called EPC (Evolved Packet Core). The EPC has a hardware configuration itself of the network device 13 applicable to a network device group of known EPCs.

  The MNO system 20 is a system managed by the MNO. An MNO is a telecommunications carrier that owns a physical network and base stations, etc., and provides mobile communication services to users. The MNO system 20 includes at least one server computer and at least one radio equipment. The server computer includes a control unit, a storage unit, and a communication unit, and their hardware configurations are the same as the control unit, the storage unit, and the communication unit of the center terminal 11, respectively. The MNO system 20 includes, for example, BSS, HSS / HLR, and SMSC. The wireless equipment is a wireless base station that directly performs wireless communication with the communication terminal 30.

  The communication terminal 30 is a computer operated by the user, and is, for example, a mobile phone (including a smart phone), a portable information terminal (including a tablet computer), a personal computer or the like. The communication terminal 30 includes a control unit, a storage unit, a communication unit, an operation unit, and a display unit.

Further, the hardware configuration of the communication system 1 is not limited to the above example, and various hardware can be applied. For example, a reading unit (for example, an optical disk drive or a memory card slot) for reading a computer readable information storage medium, or an input / output unit (for example, a USB port) for inputting / outputting data with an external device may be included. Good. For example, a program or data stored in an information storage medium may be supplied via a reading unit or an input / output unit.

[2. Outline of processing executed in communication system]
Next, an outline of processing executed by the communication system 1 will be described. Conventionally, since the MVNO does not possess the HSS / HLR and the MNO manages the HSS / HLR, the MVNO has sold the SIM card 40 issued by the MNO. Recently, the HSS / HLR has been released, allowing the MVNO to possess its own HSS / HLR. Therefore, the MVNO can issue the SIM card 40 independently rather than having the MNO issue the SIM card 40.

  Here, the outline of the process executed by the communication system 1 will be described based on the flow from when the MVNO orders the SIM card 40 to the SIM vendor and the user purchases the SIM card 40 and starts using it. Do. The SIM vendor is a business that produces an SIM card 40 in response to an order from the MVNO or MNO.

  FIG. 2 is a diagram showing a flow until the user starts using the SIM card 40. In this embodiment, the MVNO is provided with an available International Mobile Subscriber Identity (IMSI) from the Ministry of Internal Affairs and Communications. The IMSI is a unique identification number assigned to a mobile phone subscriber. Since the IMSI is stored in the SIM card 40, it can also be referred to as a unique number for each SIM card 40.

  First, the MVNO orders the SIM card 40 from the SIM vendor based on the IMSI owned by itself (S1). For example, the MVNO orders the SIM card 40 by sending an ordering list indicating the combination of IMSI and Mobile Subscriber Integrated Services Digital Network Number (MISDN) to the SIM vendor. The order list may be sent in writing or in electronic data.

  MSISDN is a telephone number assigned to the SIM card 40. MSISDN is similar to IMSI in that it can identify mobile phone subscribers, and MSISDN and IMSI correspond on a one-to-one basis. MSISDN is defined in the International Public Telephone Numbering Plan, and an available number band is defined for each MNO or MVNO. Although the IMSI can not be changed in principle once assigned to the SIM card 40, the MSISDN can be changed even after assigned to the SIM card 40. The order list describes the correspondence between IMSI and MSISDN.

  In the present embodiment, the MSISDN included in the order list is in the 020 number band. The 020 number band is MSISDN starting from 020. The 020 number band is a number band dedicated to data communication, and at the time of filing of the present application, it is not the subject of the universal fee defined to secure provision of universal services such as a joining telephone call and emergency notification.

  The SIM vendor produces the SIM card 40 based on the order list received from the MVNO, and delivers the SIM card 40 to the MVNO (S2). The SIM vendor has the SIM card 40 in which the IMSI and MSISDN are not written, and writes the IMSI and MSISDN described in the order list to the SIM card 40 using a dedicated writing device.

  In addition, it is assumed that a serial number (individual identification number) of the SIM card 40 itself is written in advance in the SIM card 40 separately from IMSI and MSISDN. The SIM vendor sends, to the MVNO, a delivery schedule list indicating a combination of the serial number of the SIM card 40, the IMSI, and the MSISDN, and delivers the SIM card 40. That is, in the delivery schedule list, correspondence relationships of serial numbers, IMSI, and MSISDN are described. The delivery schedule list may be sent in writing or may be sent electronically.

  When the MVNO receives the delivery schedule list, temporary registration of the SIM card 40 is performed between the MVNO system 10 and the MNO system 20 (S3). In the present embodiment, the user can operate the communication terminal 30 of the user to make a contract procedure of the SIM card 40, and the temporary registration is performed by setting the communication terminal 30 on which the SIM card 40 before the contract is attached to a predetermined condition. It is done to access the contract site. Details of temporary registration will be described later.

  When the temporary registration of the SIM card 40 is completed, the MVNO ships the SIM card 40 to the retail store (S4). The retail store displays the received SIM card 40 at the store or stores the SIM card 40 in a vending machine so that it can be sold to the user. At this time, since the SIM card 40 is assigned the MSISDN of the 020 number band, no universal charge occurs.

  The user purchases the SIM card 40 at the retail store (S5), and attaches the SIM card 40 to the communication terminal 30 (S6). At this point, since the SIM card 40 is in a pre-contracted and provisionally registered state, the communication terminal 30 can access only the contract site. In addition, since the SIM card 40 is assigned the MSISDN of the 020 number band, no universal charge has occurred yet.

  When the user activates the communication function of the communication terminal 30, the communication terminal 30 accesses the MVNO contract site under the control of the MVNO system 10 (S7). Although the details of the process of S7 will be described later, since the SIM card 40 attached to the communication terminal 30 is in a state of being temporarily registered, even if the user designates an arbitrary website on the browser, the communication terminal 30 is for contract You will be forced to access the site. The contract site displays an input form for the user to enter contract information, a check box indicating that the user agrees to the terms of use, and the like. For example, the terms of use agreement, rate plan selection, user name and address Input, upload of personal identification document, and selection of payment method, etc. are performed.

  When the contract site is displayed on the communication terminal 30, contract processing of the SIM card 40 is executed between the MVNO system 10 and the communication terminal 30 (S8). In S8, contract information input by the user is registered in the MVNO system 10.

  When the contract process of the SIM card 40 is completed, the MSISDN in the SIM card 40 is rewritten from the 020 number band to the 070 number band, the 080 number band, or the 090 number band using OTA (Over The Air) ( S9). The 070 number band, the 080 number band, or the 090 number band is a number band in which a call can be made, and is a number band in which a universal charge is generated. With the spread of mobile phones in recent years, the 070 number band, the 080 number band, or the 090 number band is becoming depleted, and at the stage of S9, the MSISDN of the abundant 020 number band is the MSISDN of the depleted number band. It will change to

  When the MSISDN of the SIM card 40 is rewritten, the main registration of the SIM card 40 is performed between the MVNO system 10 and the MNO system 20 (S10). This registration is performed to start using the SIM card 40. Once this registration is performed, the user will be able to access any website other than the contract site. Also, since the MSISDN of the SIM card 40 is changed to the 070 number band, the 080 number band, or the 090 number band, not only data communication but also calls can be made, and from this point on universal charges will be generated.

  As described above, in the communication system 1 of the present embodiment, the MVNO ships the SIM card 40 to the retail store with the MSISDN of the 020 number band assigned. Then, after the user makes a contract at the contract site, the MSISDN of the SIM card 40 changes to the 070 number band, the 080 number band, or the 090 number band. For this reason, in the communication system 1, for the SIM card 40 before contract, it is arranged not to consume a valuable number band which is apt to run out. Hereinafter, details of the configuration of the communication system 1 will be described.

[3. Functions Implemented in Communication System]
FIG. 3 is a functional block diagram showing an example of functions implemented by the communication system 1. Here, functions implemented by the management system 12 of the MVNO system 10, the network device 13, the MNO system 20, the communication terminal 30, and the SIM card 40 will be sequentially described.

[3-1. Functions Implemented in the MVNO System]
As shown in FIG. 3, in the MVNO system 10, a data storage unit 12A, a temporary registration unit 12B, a main registration unit 12C, and an instruction transmission unit 12D are realized in the management system 12, and in the network device 13, the data storage unit 13A. And the communication control unit 13B.

[Data storage unit of management system]
The data storage unit 12A of the management system 12 is mainly implemented as a storage unit of a server computer in the management system 12. In the present embodiment, a case where the data storage unit 12A is realized by the storage unit of the BSS in the management system 12 and the storage unit of the HSS / HLR in the management system 12 will be described. The data storage unit 12A may be realized by another server computer.

  The data storage unit 12A stores various data related to the mobile communication service provided by the MVNO. Here, a SIM information database and a user information database will be described as an example of data stored in the data storage unit 12A. For example, the SIM information database is stored in the BSS in the management system 12, and the user information database is stored in the HSS / HLR in the management system 12.

  The SIM information database is a database storing information on the SIM card 40 provided by the MVNO. For example, in the SIM information database, the serial number of the SIM card 40, the IMSI, the MSISDN, and the like are associated and stored. For example, upon receiving the delivery schedule list from the SIM vendor, the MVNO representative operates the center terminal 11 or another computer to register the combination of the serial number, IMSI, and MSISDN indicated by the delivery schedule list in the SIM information database. Do. The SIM card 40 whose data is stored in the SIM information database can be referred to as a SIM card 40 to be temporarily registered, a SIM card 40 shipped to a retail store, or a SIM card 40 sold to a user.

  The user information database is a database that stores information on users of the MVNO. For example, in the user information database, IMSI and MSISDN etc. of the SIM card 40 used by the user are stored in association with each other. The SIM card 40 whose data is registered in the user information database can use the mobile communication service provided by the MVNO. Therefore, IMSI and MSISDN are registered in the user information database in the SIM card 40 in the temporary registration state or the main registration state.

  The data stored in the data storage unit 12A is not limited to the above example. For example, the data storage unit 12A may store a vacant number database indicating vacant numbers of MSISDN. For example, in the vacant number database, vacant numbers are stored for each number band such as the 020 number band, the 070 number band, the 080 number band, or the 090 number band. The order list for ordering the SIM card 40 from the SIM vendor uses a vacant number in the 020 number band. Also, for example, at the time of main registration of the SIM card 40, vacant numbers of the 070 number band, the 080 number band, or the 090 number band are used.

  Also, for example, the data storage unit 12A may store a contract information database storing contract information input by the user at the time of contract of the SIM card 40. Further, for example, the data storage unit 12A may store display data (for example, HTML data) of the contract site.

[Provisional registration department]
The temporary registration unit 12B is mainly realized by the control unit of the server computer in the management system 12. In the present embodiment, the temporary registration unit 12B will be described as a case where the control unit of the BSS in the management system 12 is mainly realized. However, even if the temporary registration unit 12B is realized by another server computer in the management system 12 Good.

  The temporary registration unit 12B causes the communication system 1 to enter the temporary registration state in which the SIM card 40 before contract by the user can be communicated by the first MDISDN (first telephone number) belonging to the first number band. sign up.

  The SIM card 40 before contract is the SIM card 40 before contracting at the contract site, and is the SIM card 40 before this registration. That is, the SIM card 40 before contract is the SIM card 40 before the user starts using it, and is the SIM card 40 before the user is obliged to pay the charge for using the mobile communication service.

  The first number band is a group of MSISDN in which the first predetermined digit (for example, the first three digits) of the MSISDN starts with a predetermined number, and is a number band different from the second number band described later. In the present embodiment, the case where the first number band is the 020 number band will be described. Therefore, the part described as the 020 number band in this embodiment can be read as the first number band.

  For example, the first number band has more vacant numbers than the second number band. The free number is an MSISDN not assigned to any SIM card 40, and an unused MSISDN. That is, the vacant number is an MSISDN that can be assigned to the SIM card 40. The first number band can be said to be a richer number band than the second number band.

  Also, for example, the first number band is a number band in which a universal service charge is not generated. The universal service charge is for a specific number band, for example, the 070 number band, the 080 number band, and the 090 number band are for universal charges. On the other hand, universal service charges do not apply to number bands other than the above-mentioned specific number band. For example, the 020 number band is not targeted for universal charges.

  Also, for example, the first number band is a number band dedicated to data communication. The number band dedicated to data communication is a number band that can not communicate in principle, and is a number band dedicated to M2M (Machine to Machine), for example.

  The temporary registration state is a state before the main registration state is reached, and is a state in which restricted communication is possible based on the first MDISDN. The restricted communication is a state in which there are fewer accessible web sites than in the registered state, and in the present embodiment, a state in which only the contract site can be accessed. In the present embodiment, since the SIM card 40 in the temporary registration state is assigned the 020 number, it can be said that the state before the call becomes possible.

  The temporary registration unit 12B targets, among the SIM cards 40 whose data is stored in the SIM information database, the SIM card 40 for which temporary registration or main registration has not been performed yet. That is, of the SIM card 40 whose data is stored in the SIM information database, the temporary registration unit 12B still registers identification information of the SIM card 40 in the HSS / HLR in the management system 12, the network device 13, and the MNO system 20. The target SIM card 40 is not processed.

  As the identification information of the SIM card 40, any of a serial number, IMSI, or MSISDN may be used, but in the present embodiment, IMSI is used. Therefore, in the following description, the portion described as IMSI can be read as the identification information of the SIM card 40, and a serial number or MSISDN can be substituted as the identification information. The temporary registration unit 12B processes the HSS / HLR in the management system 12, the network device 13, and the SIM card 40 whose registration is not yet registered in the MNO system 20 as the temporary registration unit 12B.

  For example, the temporary registration unit 12B performs temporary registration of the SIM card 40 by recording the IMSI of the SIM card 40 on the communication system 1. For example, the temporary registration unit 12B specifies the IMSI and MSISDN of the SIM card 40 to be processed based on the SIM information database. Then, the temporary registration unit 12B performs temporary registration of the SIM card 40 by recording the IMSI and MSISDN of the SIM card 40 to be processed on the communication system 1.

  In this embodiment, the temporary registration unit 12B is a user information database in which the HSSI / HLR in the management system 12 stores IMSI and MSISDN of the SIM card 40 to be processed, a registration state database in which the network device 13 stores, and an MNO. The temporary registration of the SIM card is performed by recording in the open registration database stored in the system 20.

  In the present embodiment, temporary registration of the temporary registration unit 12B is completed through the following three steps. As a first step, the temporary registration unit 12B creates a new record in the user information database, and stores the IMSI and MSISDN of the SIM card 40 to be processed in the record. As a second step, the temporary registration unit 12B creates a new record in the registration state database, and stores the IMSI of the SIM card 40 and registration state information (described in detail later) indicating the temporary registration state in the record. As a third step, the temporary registration unit 12B transmits a predetermined temporary opening registration request to the MNO system 20, and the MNO system 20 creates a new record in the opening registration database, and the target record is processed in the record. The SIM card 40 stores IMSI and MSISDN. Thus, the temporary registration of the SIM card 40 is completed, and the contract site can be accessed.

  The process of the temporary registration unit 12B is not limited to the above example. For example, when the data storage unit 12A of the network device 13 stores not a registration state database as in the present embodiment but a temporary registration state database indicating a list of IMSI of the SIM card 40 in the temporary registration state (that is, the registration state In the case where there is no particular information), the temporary registration unit 12B may perform temporary registration of the SIM card 40 by storing the IMSI of the SIM card 40 in the temporary registration state database.

[General Registration Department]
The main registration unit 12C is mainly realized by the control unit of the server computer in the management system 12. In the present embodiment, the case where the official registration unit 12C is realized mainly by the control unit of the BSS in the management system 12 will be described, but even if the official registration unit 12C is realized by another server computer in the management system 12 Good.

  When a contract is made at the contract site, main registration unit 12C enters a main registration state in which SIM card 40 can be communicated by the second MSISDN (second telephone number) belonging to the second number band. Thus, the communication system 1 is registered.

  The second number band is a number band different from the first number band described above, and the first predetermined digit (for example, the first three digits) of the MSISDN starts with a number different from the first number band. It is a gathering. In the present embodiment, the case where the second number band is the 070 number band, the 080 number band, or the 090 number band will be described. Therefore, the part described as the 070 number band, the 080 number band, or the 090 number band in the present embodiment can be read as the second number band.

  For example, the second number band has a smaller number of vacant numbers than the first number band. For this reason, the second number band can be said to be a more exhaustive number band than the first number band. Also, for example, the second number band is a number band in which a universal service charge is generated. Also, for example, the second number band is a number band in which a call can be made. For example, in contrast to M2M, the number range in which calls can be made can be considered as a number range for H2H (Human to Human).

  The main registration state is a state in which the restriction of communication in the temporary registration state is released, and a state in which a call or data communication can be performed based on the second MD ISDN. For example, in the official registration state, there are more accessible websites than the provisional registration state, and websites other than the contract site can also be accessed.

  Among the SIM cards 40 in the temporary registration state, the main registration unit 12C sets the SIM card 40 stored in the communication terminal 30 that has received the communication request as a processing target. In other words, when the main registration of the SIM card 40 stored in the communication terminal 30 that has received the communication request has not been completed, the main registration unit 12C performs the main registration of the SIM card 40.

  For example, the main registration unit 12C records, in the communication system 1, information indicating that the SIM card 40 is in the main registration state, the MSISDN of the SIM card 40 registered on the communication system 1, the first MSISDN from the first Perform the main registration by changing to 2 MSISDN. The main registration unit 12C may select any free number among the 070 number band, the 080 number band, and the 090 number band as the second MSISDN. For example, the official registration unit 12C may select the smallest number among the vacant numbers as the second MSISDN, or may select the largest number as the second MSISDN, or may randomly select from among the vacant numbers. The second MSISDN may be selected.

  In the present embodiment, the main registration of the main registration unit 12C is completed through the following three steps. As a first step, the official registration unit 12C changes the first MSISDN of the record in which the IMSI of the SIM card 40 to be processed is stored in the user information database to the second MSISDN. As a second step, the official registration unit 12C changes the registration state information (described in detail later) of the record in which the IMSI of the SIM card 40 to be processed is stored in the registration state database to a value indicating the official registration state. . As a third step, the official registration unit 12C transmits a predetermined official open registration request to the MNO system 20, and the MNO system 20 stores the IMSI of the SIM card 40 to be processed in the open registration database. Change the first MSISDN of the previous record to the second MSISDN. From the above, the official registration of the SIM card 40 is completed, and access and call to any web site become possible.

  The process of the official registration unit 12C is not limited to the above example. For example, when the data storage unit 12A of the network device 13 stores the main registration state database indicating the list of IMSI of the SIM card 40 in the main registration state, not the registration state database in which the registration state information is associated with the IMSI (ie, In the case where the registration status information does not exist in particular, the main registration unit 12C may perform the main registration of the SIM card 40 by storing the IMSI of the SIM card 40 in the main registration status database.

[Instruction transmission unit]
The instruction transmission unit 12D is mainly realized by the control unit of the server computer in the management system 12. Although in the present embodiment, the instruction transmission unit 12D is mainly realized by the control unit of the SMSC in the management system 12, the instruction transmission unit 12D may be realized by another server computer in the management system 12. Good.

  The instruction transmission unit 12D is a writing for writing the second MSISDN to the SIM card 40 instead of the first MSISDN in the communication terminal 30 when the regular registration unit 12C places the SIM card 40 in the regular registration state. Send instructions

  The write instruction is a write command defined by the communication protocol, and is performed by transmitting data of a predetermined format. In the present embodiment, the instruction transmission unit 12D transmits a write instruction by transmitting a control SMS (OTA control signal). The control SMS is a message also called a controlled SMS, and is a signal for remotely controlling a terminal having a communication module.

  The write instruction includes the second MSISDN to be written. The second MSISDN included in the write instruction is selected by the official registration unit 12C from the vacant number of the second number band stored in the vacant number database. Before and after the main registration of the SIM card 40, the main registration unit 12C notifies the instruction transmission unit 12D of the IMSI and the second MSISDN of the SIM card 30 to be processed, and the instruction transmission unit 12D Based on the IMSI and the second MSISDN, the control SMS is transmitted as a write instruction to the communication terminal 30 to which the SIM card 30 to be processed is attached.

[Data storage unit of network device]
The data storage unit 13A of the network device 13 is mainly realized by the storage unit of the network device 13. The data storage unit 13A stores various data for controlling communication in the MVNO. Here, a registration state database will be described as an example of data stored in the data storage unit 13A.

  FIG. 4 is a diagram showing an example of data storage of the registration state database. As shown in FIG. 4, the registration state database is a database that indicates whether the SIM card 40 is in a temporary registration state or a full registration state. For example, in the registration state database, IMSI of the SIM card 40 and registration state information indicating the registration state of the SIM card 40 are associated. The registration state database may store other information. For example, the serial number of the SIM card 40 or the MSISDN may be stored.

  The registration status information is information indicating whether the SIM card 40 is in the temporary registration status or the main registration status, and, for example, a first value indicating the temporary registration status and a second value indicating the main registration status. Take any of. In the present embodiment, the network device 13 sets the value of the registration state information based on the respective instructions of the temporary registration unit 12B and the real registration unit 12C of the management system 12.

  For example, the temporary registration unit 12B transmits a predetermined request indicating temporary registration to the network device 13 together with the IMSI of the SIM card 40 to be subjected to temporary registration. When receiving the request, the network device 13 creates a new record in the registration state database, and stores the received IMSI and the registration state information of the first value.

  Further, for example, the official registration unit 12C transmits a predetermined request indicating the official registration to the network device 13 together with the IMSI of the SIM card 40 to be an object of the official registration. When the network device 13 receives the request, it changes the registration state information of the record in which the received IMSI is stored in the registration state database to the second value.

  The data stored in the data storage unit 13A is not limited to the above example. For example, the data storage unit 13A may store address information (for example, a URL, an IP address, a server name, etc.) of the contract site. Further, for example, the data storage unit 13A may store the above-described temporary registration database or main registration database when the registration state information is not particularly used.

[Communication control unit]
The communication control unit 13B is mainly implemented by the control unit of the network device 13. When the communication control unit 13B receives a communication request from the communication terminal 30 including the SIM card 40 in the provisional registration state, the communication control unit 13B causes the communication terminal to access the contract site based on the first MSISDN.

  The communication request may be made in the procedure and format defined by the communication protocol. Here, it is assumed that the IMSI stored in the SIM card 40 of the communication terminal 30 is included. Further, since the communication terminal 30 is not directly connected to the MVNO system 10 but indirectly connected via the MNO system 20, the communication control unit 13B communicates with the communication terminal 30 via the MNO system 20. The request (ie, the communication request relayed by the MNO system 20) will be received.

  For example, when the MNO system 20 receives an IMSI from the communication terminal 30, a subscriber confirmation process is performed between the management system 12 and the MNO system 20. The subscriber confirmation process is a process of confirming whether the SIM card 40 indicated by the IMSI included in the communication request is properly registered in the user information database. For example, in the subscriber confirmation process, it is checked whether the combination of IMSI and MSISDN stored in the open registration database matches the combination of IMSI and MSISDN stored in the user information database.

  When the subscriber confirmation processing is properly completed, the communication control unit 13B transfers the communication terminal 30 to the contract site when the SIM card 40 of the communication terminal 30 is in the temporary registration state, and the SIM card 40 of the communication terminal 30 is When the terminal is in the main registration state, the communication terminal 30 is made to access the connection destination corresponding to the communication request. For example, the communication control unit 13B refers to the registration state database and refers to the registration state information associated with the IMSI included in the communication request of the communication terminal 30. The communication control unit 13B transfers the communication terminal 30 to the contract site when the registration status information indicates the temporary registration status, and communicates with the connection destination corresponding to the communication request when the registration status information indicates the main registration status. The terminal 30 is made to access.

  In the present embodiment, when the communication control unit 13B receives a communication request from the communication terminal 30 including the SIM card 40 in the provisional registration state, the communication control unit 13B restricts the communication terminal 30 to access other than the contract site. That is, even when the communication terminal 30 including the SIM card 40 in the provisional registration state requests access to a website other than the contract site, the communication control unit 13B prohibits access to the website. . For example, the communication control unit 13B may not allow the communication terminal 30 to access any web site, or may forcibly transfer it to the contract site.

[3-2. Functions Implemented in MNO System]
As shown in FIG. 3, in the MNO system 20, a data storage unit 20A and a communication control unit 20B are realized.

[Data storage unit]
The data storage unit 20A is mainly implemented as a storage unit of a server computer in the MNO system 20. The data storage unit 20A stores various data related to mobile communication services provided by the MNO and the MVNO. Here, the open registration database will be described as an example of data stored in the data storage unit 20A.

  The open registration database stores information on the SIM card 40 that can use the mobile communication service, and, for example, IMSI and MSISDN of the SIM card 40 are stored. The SIM card 40 whose IMSI and MSISDN are stored in the open registration database is in a state where the communication network owned by the MNO can be used, and communication is in an open state.

  In this embodiment, the mobile communication service provided by the MNO and the mobile communication service provided by the MVNO exist. Therefore, in the open registration database, each SIM card 40 uses any mobile communication service of the MNO and the MVNO. Can be identified. For the SIM card 40 that uses the mobile communication service provided by the MVNO, the MV registration database indicates which MVNO the SIM card 40 corresponds to. Therefore, IMSI and MSISDN, and identification information of MVNO (for example, ID, business name, etc.) are associated with each other and stored in the open registration database. That is, the open registration database indicates to which MVNO system 10 the communication request of this IMSI should be transferred.

[Communication control unit]
The communication control unit 20B is mainly realized by the control unit of the server computer in the MNO system 20. When the communication control unit 20B receives a communication request from the communication terminal 30, the communication control unit 20B determines communication availability based on the open registration database. A communication request from the communication terminal 30 is received by the wireless equipment in the MNO system 20 and transferred to the communication control unit 20B. The communication control unit 20B determines whether the IMSI included in the communication request transferred from the wireless equipment exists in the open registration database.

  The communication control unit 20B permits communication when the IMSI included in the communication request exists in the open registration database, and does not permit communication when the IMSI included in the communication request does not exist in the open registration database. When the communication control unit 20B permits communication, the communication control unit 20B transfers the communication request to the MVNO associated with the IMSI included in the communication request. When the communication control unit 20B receives a communication request from the SIM card 40 using the mobile communication service provided by the MNO, the HSS / HLR in the MNO system 20 does not particularly transfer the communication request to the MVNO. Forward the communication request to

[3-3. Functions Implemented in Communication Terminals]
As shown in FIG. 3, in the communication terminal 30, a communication request transmission unit 30A is realized. The communication request transmission unit 30A is mainly realized by the control unit of the communication terminal 30. When the SIM card 40 is attached to the communication terminal 30, the communication request transmission unit 30A transmits a communication request to the MNO system 20. The communication request transmission unit 30A reads out the IMSI stored in the SIM card 40, and transmits the read IMSI included in the communication request. For example, the communication request transmission unit 30A transmits a communication request when a browser or an application is activated in the communication terminal 30 to which the SIM card 40 is attached.

[3-4. Functions Implemented on SIM Card]
As shown in FIG. 3, in the SIM card 40, a data storage unit 40A and a rewrite unit 40B are realized.

[Data storage unit]
The data storage unit 40A is mainly realized by the storage unit of the SIM card 40. The data storage unit 40A stores the serial number of the SIM card 40, the IMSI, and the MSISDN. In this embodiment, when the SIM card 40 is in the temporary registration state, the data storage unit 40A stores the serial number, the IMSI, and the first MSISDN, and when the SIM card 40 is in the main registration state, the data is stored. The storage unit 40A stores the serial number, the IMSI, and the second MSISDN.

  In the present embodiment, the first MSISDN or the second MSISDN stored in the data storage unit 40A is not included in the communication request that the communication terminal 30 transmits to the MNO system 20, but the communication request is May be included in In addition, the serial number of the SIM card 40, the IMSI, and the MSISDN stored in the data storage unit 40A may be capable of being displayed on the display unit of the communication terminal 30.

[Rewrite unit]
The rewriting unit 40B is mainly realized by the control unit of the communication terminal 30. The rewriting unit 40B rewrites the MSISDN stored in the SIM card 40 based on the write instruction. The rewriting unit 40B erases the first MSISDN stored in the SIM card 40, and writes the second MSISDN included in the write instruction. In the present embodiment, since the control SMS is used as the write instruction, the rewriting unit 40B writes the second MSISDN to the data storage unit 40A based on the execution result of the control SMS.

[4. Processing to be executed in the present embodiment]
5 and 6 are flowcharts showing an example of processing executed in the communication system 1. 5 and 6, each of the center terminal 11, the server computer (for example, BSS, HSS / HLR, SMSC) in the management system 12, the server computer in the MNO system 20, and the communication terminal 30 themselves The program is executed by operating according to the program stored in the storage unit. The process described below is an example of the process executed by the functional block shown in FIG.

  5 and 6, the SIM card 40 is delivered from the SIM vendor to the MVNO, and the person in charge of the MVNO registers the data of the delivered SIM card 40 in the SIM information database. It shall be. As described above, the SIM card 40 is assigned the first MSISDN in the 020 number band.

  As shown in FIG. 5, first, in the MVNO system 10, when the person in charge performs a predetermined operation, the center terminal 11 transmits a provisional registration request for the SIM card 40 to the BSS in the management system 12 (S100) ). The temporary registration request is a request to execute temporary registration processing of the SIM card 40 (for example, the SIM card 40 in preparation for shipping to a retail store) whose data is registered in the SIM information database, and data of a predetermined format is transmitted It is done by.

  When the BSS in the management system 12 receives the temporary registration request, the BSS cooperates with the HSS / HLR in the management system 12, the network device 13, and the MNO system 20 to execute a temporary registration process (S101). The provisional registration process of S101 is performed in the following three steps.

  As a first step, the BSS in the management system 12 sends a request for updating the user information database to the HSS / HLR in the management system 12 based on the SIM information database stored in its storage unit. The update request includes data to be registered in the user information database, and includes, for example, a combination of IMSI and MSISDN of the SIM card 40 to be temporarily registered. At this point, the first MSISDN in the 020 number band will be registered in the user information database.

  As a second step, the BSS in the management system 12 sends a temporary activation request to the network device 13. Temporary activation is processing for registering the IMSI of the SIM card 40 to be temporary registered in the network device 13. The provisional activation request includes data to be registered in the registration state database, and includes, for example, the IMSI of the SIM card 40 to be provisionally registered. When the network device 13 receives the temporary activation request, it creates a new record in the registration state database, and stores the IMSI included in the temporary activation request and registration state information indicating the temporary registration state in the record.

  As a third step, the BSS in the management system 12 transmits a temporary opening registration request to the MNO system 20. The temporary opening registration is a process of registering the IMSI of the SIM card 40 which is the target of temporary registration in the MNO system 20. The temporary opening registration request includes data to be registered in the opening registration database, and includes, for example, IMSI and MSISDN of the SIM card 40 that opens communication. When receiving the temporary opening registration request, the MNO system 20 creates a new record in the opening registration database, and stores the IMSI and MSISDN included in the temporary opening registration sky and the identification information of the MVNO in the record. . The identification information of the MVNO shall be included in the temporary opening registration request.

  As described above, the temporary registration process of the SIM card 40 in S101 is performed. At this time, since the SIM card 40 is in the 020 number band, there is no universal charge and no monthly charge for the MNO. When the temporary registration process of the SIM card 40 is completed, the MVNO ships the SIM card 40 to the retail store. When the user purchases the SIM card 40 at the retail store, installs the SIM card 40 in his own communication terminal 30, and activates the communication function of the communication terminal 30, the following processing is executed.

  The communication terminal 30 transmits a predetermined communication request to the MNO system 20 (S102). The communication request may be made in the procedure and data format defined in the communication protocol, and in this case, the IMSI stored in the SIM card 40 of the communication terminal 30 is included.

  In the MNO system 20, when the communication request is received, it is determined whether the communication terminal 30 which has made the communication request can communicate (S103). In S103, the MNO system 20 determines whether the IMSI included in the communication request is stored in the open registration database. The MNO system 20 determines that communication is possible when the IMSI included in the communication request is stored in the open registration database, and determines that communication is not possible when the IMSI included in the communication request is not stored in the open registration database. . When it is not determined that communication is possible (S103; N), the present process ends.

  On the other hand, when it is determined that communication is possible (S103; Y), a subscriber confirmation process is executed between the MNO system 20 and the management system 12 of the MVNO system 10 (S104). In S104, the MNO system 20 specifies the MVNO system 10 of the other party based on the open registration database. Then, the MNO system 20 transmits a subscriber confirmation request to the specified MVNO system 10. The subscriber confirmation request is a request for confirming whether the user information is registered in the MVNO system 10, and may be made in the procedure and data format defined in the communication protocol. When the management system 12 of the MVNO system 10 receives the subscriber verification request, it verifies the validity of the IMSI and MSISDN.

  If subscriber confirmation is performed, it will move to FIG. 6, and the display process of the site for a contract will be performed between the management system 12 of the MVNO system 10, and the communication terminal 30 (S105). In S105, a notification that the subscriber confirmation has been properly completed is transmitted from the MNO system 20 to the communication terminal 30, and the communication terminal 30 transmits the SIM card 40 to the network device 13 via the MNO system 20. Send a predetermined access request including IMSI. When the network device 13 receives the access request, the network device 13 refers to the registration status database and refers to the registration status information of the IMSI included in the access request. If the registration status information indicates the temporary registration status, the network device 13 transfers the communication terminal 30 to the contract site. Therefore, even if it is an access request to a website other than the contract site, the communication terminal 30 forcibly accesses the contract site.

  When the contract site is displayed on the communication terminal 30, contract processing is executed between the management system 12 in the MVNO system 10 and the communication terminal 30 (S106). In S106, the communication terminal 30 transmits contract information input by the user at the contract site, and the BSS in the management system 12 records the contract information input by the user in its own storage unit.

  When the contract process is executed, the second MSISDN write process is executed between the management system 12 in the MVNO system 10 and the communication terminal 30 (S107). In S107, the management system 12 transmits an OTA execution instruction to the MNO system 20. The OTA execution instruction is an instruction to rewrite the 070 number band, the 080 number band, or the 090 number band, and is performed by transmitting the control SMS. The control SMS includes a second MSISDN (a 070 number band, a 080 number band or a 090 number band MSISDN). When receiving the control SMS, the MNO system 20 transmits the control SMS to the communication terminal 30 when determining whether the communication is possible or not by the same processing as S103. When the communication terminal 30 receives the control SMS, the communication terminal 30 writes the second MSISDN to the SIM card 40. The communication terminal 30 transmits an OTA success response to the MVNO system 10, and the process of S107 is completed.

  When the second MSISDN write process is executed, the BSS in the management system 12 executes this registration process in cooperation with the HSS / HLR in the management system 12, the network device 13, and the MNO system 20. (S108), the process ends. The main registration process of S108 is performed by the following three steps.

  As a first step, the BSS in the management system 12 sends a request for updating the user information database to the HSS / HLR in the management system 12 based on the SIM information database stored in its storage unit. The update request includes data to be registered in the user information database, and includes, for example, a combination of IMSI and MSISDN of the SIM card 40 to be fully registered. At this point, the second MSISDN of the 070 number band, the 080 number band, or the 090 number band will be registered in the user information database.

  As a second step, the BSS in the management system 12 transmits the present activation request to the network device 13. This activation is processing for registering the IMSI of the SIM card 40 to be subjected to main registration in the network device 13. The activation request includes data to be registered in the registration state database, and includes, for example, the IMSI of the SIM card 40 to be registered. When the network device 13 receives the activation request, the network device 13 changes the registration state information of the record in which the IMSI included in the activation request is stored in the registration state database so as to indicate the main registration state.

  As a third step, the BSS in the management system 12 sends a main open registration request to the MNO system 20. The main opening registration is processing for registering the IMSI of the SIM card 40 to be main registration in the MNO system 20. The open registration request includes data to be registered in the open registration database, and includes, for example, IMSI and MSISDN of the SIM card 40 that opens communication. When the MNO system 20 receives the main open registration request, the MNO system 20 updates the MSISDN of the record in which the IMSI included in the main open registration request is stored in the open registration database to the second MSISDN.

  As described above, the main registration process of the SIM card 40 in S108 is performed. Since the SIM card 40 is changed to the 070 number band, the 080 number band, or the 090 number band by the main registration process, the restriction of the communication in the temporary registration process is released, and the state where the telephone call is possible. In addition, universal charges will occur and monthly fees for MNOs will also occur.

  According to the communication system 1 described above, the first MSISDN belonging to the first number band is allocated to the SIM card 40 before contract, and after the contract of the SIM card 40, the first MSISDN belonging to the second number band is allocated. By changing to the second MSISDN, consumption of the second number band for the SIM card 40 before contract can be prevented, and consumption of a specific number band can be suppressed. Also, after the SIM card 40 is changed to the second MSISDN, the first MSISDN allocated until then is released, so that the first MSISDN can be allocated to another SIM card 40. Further, since the user can attach the SIM card 40 to the communication terminal 30 and make a contract procedure by himself, it is possible to save time and effort of the retail store and the user when starting to use the SIM card 40. For example, a SIM card (so-called semi-black rom) that has conventionally been assigned MSISDN but IMSI is not registered in HSS / HLR is requested by a retailer to call MNO after the contract, HSS / HLR Although the trouble of having the IMSI registered (the trouble of manually requesting opening) has occurred, according to the communication system 1, such a trouble can be omitted. For example, a SIM card to which MSISDN is conventionally assigned and IMSI is registered in the HSS / HLR, but normal data communication and calls are restricted, and only OTA control signals are permitted (for example, The so-called OTA-ROM) is used in Mobile Number Portability (MNP), and after the contract, the retailer requests MNO by telephone etc., and it takes time and effort to write MIS ISDN of MNP to the SIM card by OTA. According to 1, such labor can be omitted.

  Also, the second number band has a smaller number of vacant numbers than the first number band, and prevents the consumption of the exhausted second number band for the SIM card 40 in the temporary registration state before contract. can do. Also, communication necessary for the contract can be performed using the abundant first number band.

  Also, since universal service charges do not occur in the first number band and universal service charges occur in the second number band, the MVNO and the user bear universal service charges for the SIM card 40 before contract. Can be prevented. In addition, since the SIM card 40 in the temporary registration state does not generate a monthly fee for the MNO, it is possible to prevent the monthly fee for the MNO from being incurred for the SIM card 40 before the contract. For example, SIM cards (so-called black roms) to which MSIS is conventionally assigned and IMSI is registered in HSS / HLR generate universal charges and monthly MNO charges even when they are in a retail store or vending machine. However, according to the communication system 1, the generation of such a charge can be prevented.

  Further, the first number band is a number band dedicated to data communication, and the second number band is a number band in which a call can be made. When the SIM card 40 in the provisional registration state before contract is called, the call unnecessary at the time of contract It is possible to prevent a specific number band having a function from being assigned.

  In addition, when a communication request from the communication terminal 30 including the SIM card 40 in the provisional registration state is received, the SIM card 40 before the contract is restricted by restricting the communication terminal 30 from accessing other than the contract website. Can be prevented from being used freely.

  In addition, since an instruction to write the second MSISDN to the SIM card 40 instead of the first MSISDN is transmitted to the communication terminal 30, the MSISDN stored in the SIM card 40 is updated using OTA. can do. Therefore, even if the user does not bring the SIM card 40 into a retail store or the like, the MSISDN of the SIM card 40 can be updated.

[5. Modified example]
The present invention is not limited to the embodiments described above. It can change suitably, in the range which does not deviate from the meaning of the present invention.

  For example, the user does not have to change the MSISDN of the SIM card 40 at the time of the contract, and the contract site is the first contract to contract as the first MSISDN or the second MSISDN. A second contract may be possible in place of MSISDN.

  The first contract is a contract for main registration without changing the MSISDN, and in the present embodiment, the contract for using the SIM card 40 in the provisional registration state as it is as the SIM card 40 dedicated to data communication. is there. The second contract is a contract for changing the MSISDN for the main registration, and in the present embodiment, a contract for using the SIM card 40 in the provisional registration state as the SIM card 40 capable of making calls.

  For example, in the contract site, a first image for making a first contract and a second image for making a second contract are displayed. The first image and the second image are images for the user to select the contract content, and are, for example, a button, a check box, or an input form displayed on the browser. The user can make a first contract by selecting the first image, and can make a second contract by selecting the second image.

  For example, when the user makes a first contract, the main registration unit 12C puts the SIM card 40 in the main registration state with the first MSISDN, and when the user makes a second contract, the SIM card with the second MSISDN. Set 40 as the official registration status. When the user makes a first contract, the main registration unit 12C puts the SIM card 40 into the main registration state without performing the process of changing the MSISDN. The details of the registration process are as described in the embodiment.

  According to the above-mentioned modification, when the user makes the first contract, the SIM card 40 dedicated to data communication can be used, and the convenience of the user is improved.

  Also, for example, the communication system 1 is applicable not only at the time of sale of the SIM card 40 but also at the time of use of the MNP. In this case, the SIM card 40 in the temporary registration state is in the state where the MNP temporary number is allocated, and the SIM card 40 in the main registration state is in the state where the number after the MNP is allocated. The temporary number of MNP is the first MSISDN, and the number after MNP is the second MSISDN. Even when using the MNP, the temporary registration process and the main registration process described in the embodiment may be performed.

  Also, for example, the second number band may have the same number of vacant numbers as the first number band, or the number of vacant numbers may be larger than the second number band. Also, for example, a universal service charge may occur in the first number band, and no universal service charge may occur in the second number band. Further, for example, the first number band may be a number band in which a call can be made, and the second number band may be a number band dedicated to data communication. Also, for example, access to a site other than the contract site may be permitted to the SIM card 40 in the provisional registration state. Also, for example, the MSISDN may not be written to the SIM card 40, and the second MSISDN may not be written by the OTA.

  Further, for example, among the functions of the communication system 1, functions other than the temporary registration unit 12B, the main registration unit 12C, and the communication control unit 13B may be omitted. Also, although the case where the temporary registration unit 12B and the real registration unit 12 are realized by the BSS in the management system 12 has been described, the temporary registration unit 12B and the real registration unit 12 may be realized in the MVNO system 12. It may be realized by HSS / HLR in the management system 12 or by the center terminal 11. Similarly, although the case where the communication control unit 13B is realized by the network device 13 has been described, the communication control unit 13B may be realized in the MVNO system 12, and the BSS or HSS / in the management system 12 may be realized. It may be realized by HLR. In this case, the data storage unit 12A of the management system 12 may store the registration state database described as being stored by the network device 13. Furthermore, although the case where the communication system 1 includes the MVNO system 10, the MNO system 20, and the communication terminal 30 has been described, only the MVNO system 10 may correspond to the communication system 1.
