The control unit 204 generates base station information indicating the communication state, and transmits the base station information to the terminal communication unit 104 of the mobile terminal 11 via the communication unit 203. When receiving the base station information, the terminal communication unit 104 transmits the base station information to the management unit 103. The management unit 103 receives the base station information.

  Further, the management unit 103 measures the received intensity from each of the retrieved small mobile communication base stations 20 as the communication state of the small mobile communication base station 20, and generates base station information indicating the communication state.

  The management unit 103 lists the received base station information and the generated base station information and displays them on the display unit 105.

  FIG. 9 is an explanatory diagram showing an example of a list of base station information displayed on the display unit 105. In FIG. 9, the base station information list 900 includes a small mobile communication base station name 901, a bandwidth 902, and a reception strength 903.

  The small mobile communication base station name 901 is the name of the small mobile communication base station, and specifies the small mobile communication base station.

  The bandwidth 902 is a communication amount of communication performed by the small mobile communication base station 20 specified by the small mobile communication base station name 901 via the fixed IP network 60. Note that the bandwidth 902 indicates “◎”, “◯”, and “Δ” in the order from the one with the smaller communication amount. Further, the smaller the communication amount, the more stable and high-speed communication can be performed.

  The reception strength 903 is a reception strength of a signal from the small mobile communication base station 20 specified by the small mobile communication base station name 901. Note that the symbol indicated by the reception strength 903 has a larger number of standing bars as the reception strength is higher. Further, the stronger the reception strength, the more stable and high-speed communication can be performed.

  When the management unit 103 displays the list of base station information, step A7 is then executed.

  In step A7, the user determines a small mobile communication base station to be connected from among the small mobile communication base stations on the list, and inputs a start request for performing communication via the determined small mobile communication base station 20 to the input unit 102.

  When receiving the start request, the input unit 102 transmits the start request to the management unit 103. When receiving the start request, the management unit 103 acquires identification information from the storage unit 101, and generates a connection request including the identification information. The management unit 103 transmits a connection request to the communication unit 203 of the small mobile communication base station 20 via the terminal communication unit 104. When the communication unit 203 receives the connection request, the communication unit 203 transmits the connection request to the control unit 204. When receiving the connection request, the control unit 204 executes Step A8.

  In step A8, the control unit 204 extracts identification information from the connection request. The control unit 204 searches the registration unit 201 for the extracted identification information, and determines whether or not the extracted identification information is registered in the registration unit 201.

  Now, since the mobile terminal 11 is a non-subscriber terminal, the extracted identification information is not registered. Therefore, the control unit 204 confirms the mode set in the setting unit 202 and determines whether or not the mode is an open mode.

  Since the mode is now the open mode, the control unit 204 approves the connection with the mobile terminal 11. When the control unit 204 approves the connection, the control unit 204 generates approval information indicating that the connection has been approved, and transmits the approval information to the terminal communication unit 104 of the mobile terminal 11 via the communication unit 203. When receiving the approval information, the terminal communication unit 104 transmits the approval information to the management unit 103. When the management unit 103 receives the approval information, it executes Step A9.

  In step A9, the management unit 103 connects to the small mobile communication base station 20 and starts communication via the small mobile communication base station 20.

When communication is performed via the small mobile communication base station 20, the security gateway 40 secures communication security by using a firewall function, a filtering function, an anti-virus / anti-spam function, and the like. If the number of mobile terminals connected to the communication base station 20 is less than the connectable number, the small mobile communication base station 20 may be connected to a plurality of non-subscriber terminals. FIG. 10 shows an example in which the mobile terminal 10 that is a subscriber terminal and the mobile terminals 11 to 13 that are non-subscriber terminals are connected to one small mobile communication base station 20.

  Independently of the above operation, the control unit 204 of the small mobile communication base station 20 monitors whether the mode set in the setting unit 202 is an open mode. When the mode is the open mode, the control unit 204 executes Step A10.

  In step A10, the control unit 204 determines at least one of the number of connections of the non-subscriber portable terminal, the connection time of the non-subscriber portable terminal, and the set time for which the open mode is set as the non-subscriber portable terminal. The value given to the user of the subscriber portable terminal is calculated according to the value. Note that the control unit 204 increases the points as the number of connections, the connection time, and the set time increase.

  When calculating the point, the control unit 204 acquires identification information from the registration unit 201 and generates an accumulation request including the point and the identification information. The control unit 204 transmits the storage request to the point management server 52 via the fixed IP network 60, the security gateway 40, and the core network 80.

  When receiving the accumulation request, the point management server 52 searches the DB 52a for point information including the identification information in the accumulation request. The point management server 52 adds the points in the accumulation request to the points in the searched point information, and updates the points to be given to the subscriber.

  Next, the operation when switching modes will be described.

  FIG. 11 is a sequence diagram for explaining an example of an operation when switching modes. It is assumed that the close mode is set for the small mobile communication base station 20.

  When receiving the execution request, the input unit 102 of the mobile terminal 10 executes Step B1.

  The input unit 102 transmits an execution request to the management unit 103. Upon receiving the execution request, the management unit 103 reads the dedicated application from the storage unit 101 and executes the read dedicated application to realize the following functions of the management unit 103.

  The management unit 103 displays an input screen for requesting input of ID and PW, which are authentication information, on the display unit 105.

  The user who has confirmed the input screen inputs the ID and PW to the input unit 102 as an application authentication request. When receiving the application authentication request, the input unit 102 transmits the request to the management unit 103. Upon receiving the application authentication request, management unit 103 executes step B2.

  In step B <b> 2, the management unit 103 transmits an application authentication request to the authentication server 51 via the terminal communication unit 104, the macro mobile communication base station 30, the operator network 70, and the core network 80. When receiving the application authentication request, the authentication server 51 executes Step B3.

  In step B3, the authentication server 51 searches the DB 51a for authentication information including the combination of ID and PW in the application authentication request, and determines whether the authentication information exists in the DB 51a.

  If the authentication information exists, the authentication server 51 generates an application authentication response indicating successful authentication. If the authentication information does not exist, the authentication server 51 generates an application authentication response indicating authentication failure. The authentication server 51 transmits the generated application authentication response to the terminal communication unit 104 of the mobile terminal 10 via the core network 80, the operator network 70, and the macro mobile communication base station 30.

  Upon receiving the application authentication response, the terminal communication unit 104 transmits the application authentication response to the management unit 103. Upon receiving the application authentication response, management unit 103 displays the application authentication response on display unit 105.

  At this time, the management unit 103 terminates the operation when the application authentication response indicates that the authentication has failed, and when the application authentication response indicates that the authentication has been successful, the screen for executing the application function provided by the dedicated application Is displayed on the display unit 105 and the user is allowed to execute the application function. Thereafter, Step B4 is executed.

  In step B <b> 4, the user of the mobile terminal 10 inputs a switching request for switching the closed mode to the open mode in the input unit 102. When receiving the switching request, the input unit 102 transmits the switching request to the management unit 103. When receiving the switching request, the management unit 103 acquires identification information from the storage unit 101, and adds the identification information to the switching request. The management unit 103 transmits a switching request to which the identification information is added to the communication unit 203 of the small mobile communication base station 20 via the terminal communication unit 104. When receiving the switching request, the communication unit 203 transmits the switching request to the control unit 204. When receiving the switching request, the control unit 204 executes Step B5.

  In step B5, the control unit 204 switches the close mode set in the setting unit 202 to the open mode. Thereafter, the control unit 204 executes Step B6.

  In step B <b> 6, the control unit 204 generates switching completion information indicating that the mode switching has been completed, and transmits the switching completion information to the terminal communication unit 104 of the mobile terminal 10. When the terminal communication unit 104 receives the switching completion information, the terminal communication unit 104 transmits the switching completion information to the management unit 103. Upon receiving the switching completion information, management unit 103 displays the switching completion information on display unit 105 and ends the operation.

  Next, the effect will be described.

  According to the present embodiment, when the mode set in the setting unit 202 is the open mode, the control unit 204 measures a value related to the non-subscriber terminal, and sends a value to the user of the subscriber terminal according to the measured value. Calculate the points to give.

  In this case, when the mode is set to the open mode, the points given to the user of the subscriber terminal are calculated according to the value relating to the non-subscriber terminal.

  Therefore, the subscriber can obtain an incentive (point) by setting the open mode. In addition, since the non-subscriber can use the stable communication via the small mobile communication base station, the convenience of the small mobile communication base station can be obtained directly and experientially. In addition, since subscribers can preferentially use small mobile communication base stations and obtain incentives based on points, the service aspect is enhanced compared with non-subscribers. It is expected to attract subscribers as new customers (subscribers).

  In the present embodiment, the value related to the non-subscriber terminal is at least one of the number of connection times of the non-subscriber radio terminal, the connection time of the non-subscriber radio terminal, and the set time in which the open mode is set. It is. Note that it is considered that the longer the set time, the greater the number of connections and the connection time of the non-subscriber wireless terminals.

  In this case, the longer the setting time for the open mode, the greater the incentive that the subscriber can obtain, so the setting time for the open mode can be lengthened. Therefore, it becomes possible to provide high-speed and stable communication to non-subscriber terminals at a high frequency.

  Moreover, in this embodiment, the communication part 203 receives the switching request | requirement containing the identification information which identifies the portable terminal from the portable terminals 10 and 11. FIG. When the identification information in the switching request received by the communication unit 203 is registered in the registration unit 201, the control unit 204 switches the mode set in the setting unit 202 according to the switching request received by the communication unit 203.

  In this case, when the identification information in the switching request received from the mobile terminal is registered, the mode is switched according to the switching request. Accordingly, the subscriber of the small mobile communication base station 20 can switch the mode by using the mobile terminal owned by the subscriber, and can easily switch the mode.

  In the present embodiment, the management unit 103 acquires base station information indicating a communication state of a small mobile communication base station in the communication range of the mobile terminal, and displays the base station information on the display unit 105.

  In this case, it is possible to confirm the communication state of the small mobile communication base station and select an optimum small mobile communication base station. Therefore, communication can be performed using the fastest and most stable small mobile communication base station.
