It is connected to the fixed telephone network 107 and another mobile communication network 108.

  The home memory station 101 stores (registers) information related to all users who use the digital mobile communication system 100. For example, terminal location information transmitted from the mobile terminal 104 as needed is stored together with the identification number of the mobile terminal 104. This terminal location information is referred to when searching for a zone (a base station 103 to which the mobile terminal 104 is located) when the mobile terminal 104 receives an incoming call. In addition, a record of calls made by the mobile terminal 104 is stored. This call record is used for charging a communication fee.

  The mobile communication switching center 102 includes a mobile communication switching device (base station control device) according to the present invention. In order to establish, open, and maintain a communication path, this mobile communication exchange performs incoming / outgoing call control, communication channel assignment, communication line connection, disconnection, and maintenance control with the base station 103. For example, when an incoming call (signal) is made to the mobile terminal 104, the mobile communication exchange inquires of the home memory station 101 about the terminal location information of the mobile terminal 104. Then, channel setting is performed for the base station 103 where the mobile terminal 104 is located to perform incoming call transfer control. In addition, when the mobile terminal 104 in communication (call) moves, the mobile switching center 102 tracks the mobile terminal 104 between the mobile switching centers 102 so that communication can be continued (handover). The mobile communication switching center (gate exchange) 102 is connected to the fixed telephone network 107 and other mobile communication networks 108 to realize communication including calls with the fixed telephone network and other mobile communication networks. Similarly, when a call is received by the mobile terminal 104 via the fixed telephone network or another mobile communication network, the mobile communication switching center 102 sends the terminal location information (and the mobile terminal 104) to the home memory station 101. The base station 103) is inquired, and incoming call transfer control is performed for the base station 103 where the terminal is located.

  The base station 103 is a radio base station, for example, receives a call signal from the mobile terminal 105 to the mobile terminal 104, transfers the call, and transmits the call signal to the mobile communication switching center 102. Relay. The base station 103 nearest to the mobile terminal 104 receives an incoming call signal from the mobile switching center 102 to the mobile terminal 104, and sets a general call channel (control channel) to the mobile terminals in the radio zone. Use and wirelessly transmit control signals. In response to this, the mobile terminal 104 establishes a communication path (call) with the mobile terminal 105 which is the counterpart communication terminal.

  The management DB 204 is a DB (Data that is registered in association with the telephone number of the mobile terminal 104, the telephone number of the administrator's mobile terminal 106, and the telephone number of the mobile terminal 105 that is permitted to receive calls to the mobile terminal 104. Base), but will be explained in detail later.

(Management DB)
Next, the management DB 204 will be described in detail. FIG. 3 is a schematic diagram showing the data structure of the management DB 204. The management DB 204 includes, as data fields, “ID”, “manager telephone number”, “manager 1 telephone number”, “manager 2 telephone number”, “valid manager”, “approval telephone number”, “approval management”. Person ”,“ registration date ”and the like. The management DB 204 is a DB in which the telephone number of the mobile terminal 104, the telephone number of the administrator's mobile terminal 106, and the telephone number of the mobile terminal 105 that is permitted to receive calls to the mobile terminal 104 are associated and registered. . The mobile communication switching system 1 according to the present invention refers to the management DB 204 when a call is received from the mobile terminal 105 to the mobile terminal 104, and connects to the mobile terminal 104 as it is or connects to the mobile terminal 106. Perform connection control.

  “ID” is a management unique identifier assigned to each “managed person telephone number”. The “management target person telephone number” corresponds to the telephone number of the mobile terminal 104, and in this field, the telephone number of the mobile terminal that is required to be approved by the administrator at the time of an incoming call is registered. For example, the phone number of the child's mobile phone to be protected.

  “Administrator 1 telephone number” and “Administrator 2 telephone number” correspond to the telephone number of the mobile terminal 106, and in this field, the telephone of the mobile terminal of the administrator who approves the incoming call to the mobile terminal 104. The number is registered. “Manager 1 phone number” and “Manager 2 phone number” are provided so that a plurality of managers can be registered (not limited to only two). For example, manager 1 is a parent of a child, The manager 2 is a field used like a teacher at a child's school. The “effective administrator” is a field in which an administrator who is currently effective as an administrator is registered. In the case of “1”, the approval is performed by the administrator 1, and in the case of “2”, the approval is performed by the administrator 2. In the case of “1, 2”, a call for approval is first transferred by the administrator 1, but in the case of absence, a call for approval is transferred to the administrator 2 next. Also good. Here, it is assumed that the administrator authority is stronger in the order of the administrator 1 and the administrator 2. When the “approval phone number” is canceled (deleted), the administrator 1 has the approval phone number that the administrator 2 has approved as well as the approval phone number that the administrator 1 has approved. It is possible to cancel. On the other hand, the manager 2 can cancel the approval telephone number approved by the manager 2, but cannot cancel the approval telephone number approved by the manager 1. In this way, a plurality of managers are provided to enable flexible operation of approval.

  The “approval telephone number” is the telephone number of the mobile terminal whose call has been approved by the administrator to the mobile terminal of the management target person. Therefore, the telephone number of the mobile terminal once approved and registered in this field can be subsequently called to the mobile terminal of the management subject without the administrator's approval.

  The “approval manager” is a field in which the manager who has approved the “approval telephone number” is registered, and the “registration date / time” is a field in which the date / time when the “approval telephone number” is registered is registered.

  The overall configuration of the digital mobile communication system 100 according to the embodiment of the present invention has been described above. In this configuration, the (processing) operation of the mobile communication switching device 1 will be specifically described below. Each of these functional units described above is actually realized by a program executed by the CPU.

<Operation>
(Overview)
The processing operation of the mobile communication switch 1 according to the present invention will be described. Following the flow, I will explain in order. FIG. 4 is an example of a diagram for explaining the outline of the digital mobile communication system 100 according to the present invention. Here, as described above, the mobile terminal 104 is a mobile terminal owned by a child, and the mobile terminal 105 is a mobile terminal owned by a third party (unknown caller). Make an incoming call. The mobile terminal 106 is assumed to be a mobile terminal of an administrator who manages the mobile terminal 104 and is owned by a child's guardian (parent).

  In step S401, the unknown caller calls the child. In step S402, the mobile communication switch 1 performs connection control for the guardian (not registered in the management DB). In step S403, the telephone is transferred (connected) to the guardian. For example, a direct call (conversation) is made between the unknown caller and the guardian, and the guardian determines whether or not to approve the call between the unknown caller and the child. In the case of approval, a predetermined operation of the mobile terminal is performed (for example, the operation button “1” is pressed).

  When the approval signal is received by the mobile communication switch 1 in step S404, the telephone number of the mobile terminal 105 of the unknown caller is registered in the management DB 204. In step S405, the child is caused to receive a call, and in step S406, a call is made between the unknown party and the child.

  In this way, when a call (incoming call) is received from an unknown caller, the call is once transferred to the guardian, and the guardian approves whether or not to allow the call to the child. A call is made between the caller and the child. With such a configuration, an incoming call from an unapproved partner can be prevented and the mobile terminal holder can be protected. Next, it will be described in detail with reference to a flowchart.

(Processing operation)
FIG. 5 is a flowchart showing call connection control processing of the mobile communication switching system 1 according to the present invention. A description will be given below.

  In step S501, the mobile terminal 105 is a mobile terminal owned by a third party (unknown caller) and makes an incoming call (call) to the mobile terminal 104.

  In step S <b> 502, the connection control unit 201 refers to the management DB 204 and determines whether or not the called party is a telephone number to be subjected to call connection control according to the present invention. Specifically, the determination is made based on the presence / absence of registration in the “management target person telephone number” in the management DB 204. If registered, the process proceeds to step S503. On the other hand, if there is no registration, the process proceeds to step S508, and the connection control unit 201 transfers the call to the mobile terminal 104 as it is (call establishment).

  In step S <b> 503, the connection control unit 201 refers to the management DB 204 to determine whether the call source is a telephone number (source telephone number) that is permitted (approved) to the mobile terminal 104. judge. Specifically, the determination is made based on the presence / absence of registration in the “approval telephone number” of the management DB 204. If registered, the process proceeds to step S508, and the connection control unit 201 connects the call to the mobile terminal 104 as it is (call establishment). On the other hand, if there is no registration, the process proceeds to step S504.

  In step S504, the connection control unit 201 refers to the management DB 204 and connects the call from the mobile terminal 105 to the “manager 1 telephone number”. Specifically, it is connected to the mobile terminal 106 of the manager who owns the guardian (parent) of the child and manages the mobile terminal 104. As a connection (approval) destination, the “valid administrator” field of the management DB 204 is referred to, and “administrator 1 telephone number” or “administrator 2 telephone number” is set to be approved. Yes. For example, the manager 1 may be a child's parent, and the manager 2 may be a child's school teacher. Further, the manager 1 may be a department manager, and the manager 2 may be a recent boss or the like.

  In step S505, the approval signal acquisition unit 202 provides an approval unit. For example, “The call from the person who wants to approve will be transferred. The call will be started from now. To approve, press the operation button“ 1 ”, otherwise press“ 2 ”. . When “1” is pressed, the call is transferred to the management target. If you press “2”, the call will be disconnected. ”To prompt the administrator for approval. The administrator performs a predetermined operation according to the instruction. Here, since the administrator (eg, the guardian) can directly talk with the third party (unknown caller), the call with the management subject (eg, the child) is approved in the call. You can decide whether or not you should. In this way, an incoming call from an unknown caller (partner) can be prevented with high accuracy, and the management subject can be protected.

  In step S506, the approval signal acquisition unit 202 acquires an approval signal (or non-approval signal) by a predetermined operation of the administrator. Here, if the non-approval signal is acquired, the call is not approved, and the call is disconnected in step S509. On the other hand, if the approval signal is acquired, the process proceeds to step 507. Further, the communication in steps S505 and S506 will be described later again.

  In step S <b> 507, the registration unit 203 registers the telephone number of the mobile terminal 106 in the “approved telephone number” field of the management DB 204 as the telephone number of the mobile terminal that is permitted to receive calls to the mobile terminal 104. Also, the approved manager is registered in the “approval manager” field. As long as the mobile terminal 106 is registered in the management DB 204, it can make an incoming call to the mobile terminal 104 without an approval operation thereafter.

  In step S508, the connection control unit 201 connects a call from the mobile terminal 105 to the mobile terminal 104. Specifically, a third party (unknown caller) makes an incoming call to the child and makes a call. Here, it is also possible to adopt a configuration in which the call from the mobile terminal 105 is disconnected after being registered in the management DB 204 (step S507). At the time of disconnection, a voice announcement such as “Approved. Once disconnected, please try again. You can talk directly after the next time” is provided. Since the telephone number of the mobile terminal 106 is registered in the management DB 204 as the telephone number of the mobile terminal that is permitted to receive calls to the mobile terminal 104, a call can be made without approval thereafter.

(Call sequence)
Next, a call flow in the digital mobile communication system 100 will be described. FIG. 6 is a sequence diagram illustrating a call flow.

  In step S <b> 601, the mobile terminal 105 makes an incoming call (outgoing call) to the mobile terminal 104.

  In step S602, the connection control unit 201 refers to the management DB 204 to determine whether or not the called party is a telephone number to be subjected to call connection control according to the present invention. Here, it is assumed that there is no registration.

  In step S603, the approval signal acquisition unit 202 transmits (calls) a control frame related to acquisition of an approval signal to the mobile terminal 104 (position information of the mobile terminal 104 is acquired from the home memory station 101). The control frame requests the response frame including the above-described voice announcement (telephone transfer for approval) and an approval flag by a predetermined approval operation on the transfer terminal 106 side. A call (transaction ID) from the mobile terminal 105 is managed and linked to the control frame. Note that, after the control frame transmission (call origination), until the call from the mobile terminal 105 is connected, the mobile terminal 105 receives an incoming call once. “Now, the call is being transferred to the approver. Please wait. "

  In step S604, the connection control unit 201 connects a call from the mobile terminal 105 (call establishment) following control frame transmission (call origination).

  In step S605, prompted by the voice announcement described above, a predetermined approval operation is performed on the transfer terminal 106 side, and a response frame including an approval flag indicating approval or non-approval is returned. At the same time as a predetermined approval operation is performed, the call from the mobile terminal 105 is put on hold.

  In step S606, if the approval signal acquisition unit 202 refers to the approval flag and indicates approval, the registration unit 203 sets the mobile terminal 105 as the telephone number of the mobile terminal permitted to receive a call to the mobile terminal 104. Are registered in the management DB 204. On the other hand, if it indicates non-approval, it is not registered in the management DB 204.

  In step S607, if the approval flag indicates approval (if registered in the management DB 204), the connection control unit 201 connects the call on hold to the mobile terminal 104. . On the other hand, if the approval flag indicates non-approval (unless registered in the management DB 204), the connection control unit 201 disconnects the call on hold to the mobile terminal 104.

  As described above, according to the mobile communication switching system 1 according to the present invention, when a call is made from an unapproved caller (incoming call), the call is once transferred to the administrator, and the administrator permits the call to the administrator. After the approval of whether or not, the call between the caller and the management subject is performed. With such a configuration, for example, an incoming call from an unapproved partner can be prevented, and a child held by the mobile terminal can be protected. In addition, as a usage, when making a call related to business confidentiality, incoming calls from unapproved parties can be prevented, and calls with persons holding mobile terminals only from approved parties (related parties) can be made. Can be protected.

Since the processing operation is substantially the same as that of the above-described embodiment, only a brief description will be given. FIG. 10 is an example of a diagram for explaining an outline used in the digital mobile communication system 200 according to the present invention. Here, as described above, the mobile terminal 104 is a mobile terminal owned by a child, and the mobile terminal 105 is a mobile terminal owned by a third party (unknown mail sender). Send an email. The mobile terminal 106 is assumed to be a mobile terminal of an administrator who manages the mobile terminal 104 and is owned by a child's guardian (parent).

  In step S1001, an unknown mail sender sends a mail to the child. In step S1002, the mobile communication switching system 2 performs mail transfer control for the guardian (no registration in the management DB). In step S1003, the mail is transferred to the guardian. Then, the guardian determines whether or not the unknown mail sender approves the mail transmission to the child.

  In step S1004, when the approval information is received by the mobile communication switch 2, the mail address of the mobile terminal 105 of the unknown mail sender is registered in the management DB 214. In step S1005, a mail is transmitted to the child. In this way, when sending an email from an unknown email sender, once the email is forwarded to the guardian, the guardian approves whether to allow the email sender to the child, An email from an unknown email sender is sent to the child. With such a configuration, it is possible to protect the mobile terminal holder by preventing mail transmission from an unapproved partner.

(Transfer sequence)
Next, a mail transfer flow in the digital mobile packet communication system 200 will be described. FIG. 11 is a sequence diagram illustrating the flow of mail transfer.

  In step S <b> 1101, the mobile terminal 105 transmits mail to the mobile terminal 104.

  In step S1102, the transfer control unit 211 refers to the management DB 214, and determines whether the mail transmission destination is a mail address to be subjected to transfer control according to the present invention. Here, it is assumed that there is no registration.

  In step S <b> 1103, the approval information acquisition unit 212 transmits an email regarding acquisition of approval information to the mobile terminal 104 (position information of the mobile terminal 104 is acquired from the home memory station 101). FIG. 12 shows an example of an email related to obtaining approval information. For example, an administrator (guardian) is notified that an email has been sent from an unapproved email address (unknown email sender) to a management subject email address (child), a guidance message prompting an approval operation, and a mobile terminal The mail text transmitted from 105 is included. The administrator (guardian) performs an approval operation of “approval” when approving this, “non-approval” when not approving, and “approve only this time” when approving only this time. It should be noted that an email for obtaining approval information corresponds to a tag for transmitting an approval (or non-approval) flag corresponding to each approval operation to the mobile communication switch 2 (for example, each option of approval or non-approval). Embedded tags, etc. that represent buttons and hyperlinks).

  In step S1104, an approval (or non-approval) flag is transmitted to the mobile communication switch 2 by an approval operation, and the approval information acquisition unit 212 acquires this. Note that the transfer control unit 211 holds the mail transmitted from the mobile terminal 105 until the approval (or non-approval) flag is transmitted from the administrator (guardian) mobile terminal 106.

  In step S 1105, if the approval signal acquisition unit 212 refers to the flag and indicates approval, the registration unit 213 uses the mobile terminal 105 as the mail address of the mobile terminal that is permitted to send mail to the mobile terminal 104. The mail address is registered in the management DB 214. On the other hand, if it indicates non-approval, it is not registered in the management DB 214. In addition, information indicating approval only this time is not registered in the management DB 214.

  In step S1106, if the flag indicates approval (if registered in the management DB 214), the transfer control unit 211 transfers the stored mail to the mobile terminal 104. On the other hand, if the flag indicates non-approval (unless registered in the management DB 214 for registration), the mail is discarded. Furthermore, it is preferable to generate and send an email for guiding (explaining) the non-approval to the mobile terminal 105.

  As described above, according to the mobile communication switching system 2 according to the present invention, when mail is sent from an unapproved mail sender, the mail is once transferred to the manager, and the manager permits the manager to send the mail. Whether or not it is possible to send a mail from the mail sender to the management target person. With such a configuration, for example, mail transmission from an unapproved partner can be prevented, and a child held by the mobile terminal can be protected. In addition, as an application, when sending an email related to business confidentiality, it is possible to prevent an email from an unapproved partner, and to send an email only from an approved partner (related party) to a person holding a mobile terminal, Business secrets can be protected.

  This embodiment is an embodiment in which the previous embodiments are combined. That is, “call” was handled in Example 1, and “mail” was handled in Example 2. Therefore, the mobile communication switch 3 according to the present embodiment has a configuration for handling both. Since the details have already been described, only the function and management DB of the mobile communication switch 3 according to the present invention will be described here.

  FIG. 13 is a functional block diagram showing the main functions of one embodiment of the mobile communication switch 3 according to the embodiment of the present invention. The mobile communication switch 3 includes a connection control unit 201, an approval signal acquisition unit 202, a transfer control unit 211, an approval information acquisition unit 212, a registration unit 223, and a management DB 224 as main functions. The customer DB 230 in the figure will be described later. Since the details of each functional unit are as described above, description thereof is omitted.

  FIG. 14 is a schematic diagram showing the data structure of the management DB 224. As shown in FIG. The management DB 224 has a data structure in which the data fields of the management DB 204 and the management DB 214 are stored in one DB.

  Here, the digital mobile communication system according to the present embodiment has a customer DB 230 in configuration. The customer DB 230 is a DB in which information related to a mobile terminal such as a user's customer, contract information, billing (payment) information, telephone number, and mail address is centrally managed. Therefore, by associating the data of the customer DB 230 and the management DB 224, the data field “approval telephone number” and “approval mail address” of the management DB 224 can be associated (linked). If the phone number is approved by the administrator using this, the mail address is also treated as being approved. The reverse can be approved as well.

  Also, the email address is often changed frequently. Therefore, since the customer DB 230 has the email address change information, it is assumed that if the email address has been approved once by linking the data of the customer DB 230 and the management DB 224, the email address after the change is also approved as it is. By handling it, it is possible to reduce the trouble of re-approving after changing the mail address.

<Summary>
As described above, when the mobile communication switching system according to the present invention receives communication from an unapproved partner to a managed mobile terminal, the communication is once transferred to the manager, and the manager is transferred to the managed person. On the other hand, after approving whether to permit communication, communication between the partner and the management subject is performed. With such a configuration, for example, communication from an unapproved partner can be prevented, and a child held by the mobile terminal can be protected. In addition, when communication related to business confidentiality is performed as an application, communication from an unapproved partner can be prevented and business confidentiality can be protected.
