Description

  The present invention relates to a mobile terminal system that can control a mobile terminal such as a mobile phone.

  This type of mobile terminal system includes a mobile terminal such as a mobile phone, a base station, a radio control station, an exchange, and a network. Here, the portable terminal includes, for example, a portable information terminal (PDA) having a wireless telephone function, a personal computer such as a notebook personal computer, and the like, in addition to the portable telephone. Hereinafter, a mobile phone will be described as an example of a mobile terminal.

  Recently, due to the rapid development of mobile phones (high performance and low price), mobile phones have become widespread not only for business use but also for ordinary households. Therefore, abuse of children's mobile phones (parents pay the fee) who do not have self-payment ability, or indiscriminately calling children who do not know where to use the mobile phones, are problematic. Has become. In addition, there is a need in business use to permit only a specific partner to contact a mobile phone and change this specific partner at any time. At present, various issues such as using prepaid mobile phones, setting a certain amount of usage upper limit by the telephone company, or restricting (or permitting) the connection of only a specific phone number are currently available. By adding the function to a mobile phone, it is possible to restrict a specific amount of money or to deter (or permit) a specific telephone number.

For example, as a method of managing the upper limit of the mobile phone usage amount, Patent Literature 1 describes a method of setting and managing the number of connections that can be collectively used by a plurality of mobile devices. In this method, for each group to which a plurality of mobile devices belong, the number of mobile terminals that can be communicated with by the mobile devices belonging to the group and the number of the mobile device are stored in association with each other in the storage means. In this case, the number of communicable connections is set collectively.

  As described above, in the conventional mobile phone, the upper limit of the usage amount, the connection suppression (or permission) of the specific partner, and the like can be set at the time of the mobile phone contract or at an arbitrary time. However, in the past, for example, parents must deter children from abusing their mobile phones or indiscriminately calling children who are uneconomically unfavorable, and allowing them to automatically connect to secure parties. Was not taken into consideration, and operability was not sufficient.

  Therefore, an object of the present invention is to provide a mobile terminal system that can suppress communication by a mobile terminal by another mobile terminal. Another object of the present invention is to provide a mobile terminal system that can automatically connect to a partner whose connection is apparent to have no problem without intervening operations or time-consuming processing. It is in.

  The above object is to group a plurality of mobile terminals and the plurality of mobile terminals, register one or more mobile terminals in the same group as a parent device, and register one or more remaining mobile terminals as slave devices. The present invention is achieved by a portable terminal system including a group database, and based on the group database, allowing the master unit to control incoming and / or outgoing calls of slave units in the same group.

  Here, the master unit refers to a portable terminal having the authority to restrict incoming and / or outgoing calls of the slave unit, and the slave unit refers to a portable terminal subject to the restriction. The group database may be provided in at least one of an exchange, a radio control station, and a base station connected to a network. In the present system, when an incoming call or outgoing call request is issued in the slave unit, a permission confirmation message of the incoming call or outgoing call of the slave unit is issued to the master unit in the same group based on the group database. The master unit may return a response message for permitting or denying the incoming or outgoing call of the slave unit.

  Further, the group database includes a telephone number of the slave unit, a destination telephone number or an e-mail address to which connection with the slave unit is permitted or denied, a filtering condition for defining a condition for permitting or denying the connection, and And a table having a transfer mode for setting an outgoing / incoming mode of the slave unit. The filtering condition may be, for example, a time period during which the connection is permitted or denied. The transfer mode may include each mode of permitting or rejecting the outgoing / incoming call of the slave unit or confirming transfer to the master unit. In the case where the transfer mode is a mode requiring transfer confirmation to the master unit, if a call or call request is issued in the slave unit, the slave unit receives or calls the master unit in the same group. Is issued, and the parent device can return a response message of permission or denial with respect to the incoming call or call request of the child device. The result of the permission or denial of the incoming call or the call request of the child device by the parent device may be stored in the group database.

  An exchange according to the present invention includes a group database in which a plurality of portable terminals are grouped, and one or more portable terminals in the same group are used as a parent device and the remaining one or more portable terminals are registered as child devices. The parent device can control incoming and / or outgoing calls of the child devices in the same group based on the group database. The group database may include, in advance, a setting for permitting or rejecting an incoming call and / or an outgoing call of the slave unit when the master unit cannot communicate. The group database is a telephone number of the slave unit, a destination telephone number or an e-mail address for which connection with the slave unit is permitted or denied, a filtering condition for defining a condition for permitting or denying the connection, and It may include a table having a transfer mode for setting the outgoing / incoming mode of the handset.

A computer-readable recording medium according to the present invention records such a portable terminal control program.

  ADVANTAGE OF THE INVENTION According to this invention, communication by a portable terminal is suppressed by another portable terminal, and automatic connection is performed without intervening operations or time-consuming processing for a partner who is clearly connected and has no problem. It is possible to obtain a mobile terminal system that can be connected to the network.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a mobile phone will be described as an example of a mobile terminal. However, the present invention is not limited to this, and can be applied to mobile terminals in general, and includes not only communication by telephone but also communication by e-mail and the like. It is a thing.

  FIG. 1 is a diagram showing an example of an embodiment of a portable terminal system according to the present invention. As shown, a mobile phone (parent device) 101, a mobile phone (child device) 102, and a mobile phone (other device) 103 can be wirelessly connected to their corresponding base stations 104. The base station 104 is connected to a radio control station 105 that controls the base station. A plurality of radio control stations are provided, which are connected to an exchange (exchange) 109. The switching center 109 is connected to the network 107. A general subscriber telephone (other device) 108 is connected to the line network 107.

  With such a configuration, it is possible to mutually communicate between each mobile phone and the subscribed phone. For example, base unit 101 can communicate with base station 108 via base station 104, radio control station 105, switching center 109, and network 107. Further, for example, the slave unit 102 can communicate with the mobile phone 103 via the base station 104 and the wireless control station 105. However, in the present mobile terminal system, a group database 106 for managing a group of mobile phones is further provided in the exchange 109, for example.

  FIG. 2 is a diagram showing a telephone number table as an example of a table structure of the group database. The telephone number column 201 stores the telephone number of the subscribing mobile phone, and the parent / child flag column 202 stores a parent or child indicating whether the mobile telephone of the corresponding record is a parent device or a child device. In the case where the mobile phone of the corresponding record is a slave unit, the main unit telephone number of the group is stored in the column 203 of the main unit telephone number, and the column 204 of the corresponding record is stored in the column 204 of the group name. .. Are stored in the column 205 for setting when communication is not possible, when the mobile phone of the corresponding record is a slave, The communication permission / rejection setting for permitting or rejecting this communication is stored.

  This table has a structure in which a corresponding record can be easily extracted by using the telephone number as an index, for example, by sorting the telephone numbers stored in the telephone number column 201. In this example, for example, in group A, the telephone number 123-0000-1111 is the parent device, and the telephone numbers 123-0000-3333 and 123-0000-3334 are the child devices.

  Further, in the example of this table, one master unit in the group is assumed, but a plurality of master units may be provided. In this case, assuming a case where one base unit is busy, the power is off, or out of the service area, a table in which the priority order of the base units is set in the group database is prepared, and the table is set in order of priority. The method of requesting permission is easily applicable.

  Further, in the setting column 205 when communication is not possible, it is assumed that all master units or a specific master unit cannot be connected. If the master unit cannot be connected, a connection request to / from the slave unit is permitted. , Or not allowed. This is because, for example, when the setting in the communication-disabled setting column 205 indicates that communication is permitted, the corresponding child device is permitted to communicate with the partner device in the through state, while the setting when communication is disabled is determined as communication rejection. In the case of, the corresponding slave unit gives up and the communication with the partner unit is rejected.

  3A to 3E are diagrams illustrating display examples on the display unit of the mobile phone. FIG. 3A is a slave unit display screen at the time of a slave unit call request, and is a screen showing a state in which the master unit is performing permission determination when the slave unit calls the other unit. FIG. 9B shows a parent device display screen at the time of a child device call request. When the child device makes a call to the other device, a screen for determining whether or not the parent device permits connection of the child device (child device->). Partner). The permission / prohibition button in this screen can be operated in conjunction with a menu button or a number button provided on the mobile phone. FIG. 8C is a display screen of the other device when a call is requested from the other device to the slave device, and is a screen showing a state in which the parent device determines permission when the other device requests the slave device to receive a call. . FIG. 4D shows a master unit display screen when a call is requested from a partner to a slave unit. When the partner unit requests a slave unit to call, a determination is made as to whether the master unit is permitted to connect to the slave unit. It is a screen (partner-> child device). In this case, as in (b), the permission / prohibition button on the screen can be operated in conjunction with a menu button or a number button provided on the mobile phone. FIG. 7E shows a display screen when the parent device connection is rejected, which is a child / other device common rejection result display screen when the connection request is rejected by the parent device. In this case, both screens indicate that the connection has been refused by the master unit and that the line is disconnected, for example, as shown in the figure.

  FIG. 4 is a diagram showing an example of a signal flow at the time of a call request from a slave unit in the portable terminal system according to the present invention. First, as in step S1, when there is a call request from the slave unit 102, the call request is transmitted via the base station 104 and the radio control station 105 and processed by the exchange 109. In step S2, the exchange 109 searches the telephone number table (FIG. 2) in the group database 106 based on the telephone number of the call request source. More specifically, the telephone number of the call request source is searched in the telephone number column 201 of the telephone number table, the parent / child flag in the parent / child flag column 202 is determined, and the call request source is a child. Then, the main phone number is extracted from the main phone number column 203. If the call request source is the parent, the connection is made as it is.

  In this example, since the call request source is a child, in step S3, a transfer enable / disable confirmation message (message) is transmitted to the master unit corresponding to the extracted master phone number. At this time, the screen of the parent mobile phone is displayed on the screen of FIG. 3B, and the screen of the slave mobile phone is displayed on the screen of FIG. In step S4, the parent device 101 operates to permit or prohibit (deny) the transfer on the display screen of FIG. 3B, and the exchange 109 receives the result. At this time, as a factor for the parent device to determine the permission, not only the display contents by the electronic message but also a method of directly making a determination after talking with the sender can be easily applied.

  Here, when the parent device 101 permits the transfer, the process proceeds to step S5, and when the transfer is not permitted (denied), the process proceeds to steps S6 and S7. That is, when the transfer of the master unit is permitted, in step S5, the exchange 109 connects to the partner unit 103 or 108 via the line network 107. As a result, the connection between the slave unit and the partner unit is established, and conversation can be performed. On the other hand, when the transfer of the master unit is denied, in step S6, the exchange 109 transmits a transfer denial report message to the slave unit 102. The slave unit 102, upon receiving the denial report message, displays the screen shown in FIG. Then, in step S7, switching center 109 disconnects the connection with slave unit 102. If it is not possible to connect to all master units or a specific master unit, as described above, the connection request from the slave unit is permitted or rejected in accordance with the designation in the communication disabled setting column 205 in FIG.

  FIG. 5 is a diagram showing an example of a signal flow at the time of an incoming call request to a slave unit in the portable terminal system according to the present invention. First, as in step R1, when there is a call request from the partner device 103 or 108 to the slave device 102, the call request is transmitted via the line network 107 and processed by the exchange 109. In step R2, the exchange 109 searches the telephone number table (FIG. 2) in the group database 106 based on the telephone number of the call request destination. Specifically, the telephone number of the call request destination is searched in the telephone number column 201 of the telephone number table, the parent / child flag in the parent / child flag column 202 is determined, and the call request destination is a child. Then, the main phone number is extracted from the main phone number column 203. If the call request destination is the parent, the connection is made as it is.

  In this example, since the call request destination is a child, in step R3, a transfer enable / disable confirmation message (message) is transmitted to the base unit corresponding to the extracted base unit telephone number. At this time, the screen of the parent mobile phone is displayed on the screen of FIG. 3D, and the screen of the partner mobile phone is displayed on the screen of FIG. 3C. In step R4, the parent device 101 operates to permit or prohibit (deny) the transfer on the display screen of FIG. 3D, and the exchange 109 receives the result. At this time, as a factor for the parent device to determine the permission, not only the display contents by the electronic message but also a method of directly making a determination after talking with the sender can be easily applied.

  Here, if the parent device 101 permits the transfer, the process proceeds to step R5, and if the transfer is not permitted (denied), the process proceeds to steps R6 and R7. That is, when the transfer of the master unit is permitted, in step R5, the exchange 109 connects to the slave unit 102 via the radio control station 105 and the base station 104. As a result, the connection between the slave unit and the partner unit is established, and conversation can be performed. On the other hand, when the transfer of the master unit is denied, in step R6, the exchange 109 transmits a transfer rejection report message to the partner unit 103 or 108. Upon receiving the denial report message, the partner machine displays the screen shown in FIG. Then, in step R7, the exchange 109 disconnects the connection with the partner device 103 or 108. If it is not possible to connect to all master units or a specific master unit, as described above, the connection request to the slave unit is permitted or rejected in accordance with the designation in the communication disabled setting column 205 of FIG.

  With this configuration, communication by the mobile terminal can be more appropriately suppressed by another mobile terminal. In addition, it is preferable that a connection can be automatically established with respect to a partner whose connection is known to have no problem without intervening operations or time-consuming processing. Next, a portable terminal system for realizing this will be described.

  FIG. 6 is a diagram showing a slave unit transmission / reception control table as another example of the table structure of the group database. The telephone number column 301 stores the telephone number of the slave unit, and the recognition pattern 302 stores a recognition pattern instructing a method of recognizing a telephone number or an e-mail address of a partner to be automatically permitted or rejected. The telephone number or e-mail address of the partner to be permitted or rejected is stored in the other party's telephone number / e-mail address column 303. As the recognition pattern, with respect to the other party's telephone number / e-mail address, for example, a fixed character, a leading character string, an intermediate character string, an e-mail attached file name, all other than designated, and the like can be selected, but the present invention is not limited to this. The time zone column 304 stores the time zone in which the outgoing / incoming call of the slave unit is controlled. In other words, the designated time zone is subject to outgoing / incoming control, and other than the designated time zone is not subject to outgoing / incoming control. The transfer mode column 305 stores “−” mode, “permit” mode, and “deny” mode, respectively. The “−” mode is set as a default, and is a mode in which the master unit needs to be confirmed. In the “permission” mode, communication is permitted without requiring confirmation of the master unit. In the “reject” mode, communication is disabled because no parent device confirmation is required. As a result, for example, from a portable terminal or a computer (personal computer) connected to the Internet, the master unit sets a destination to automatically permit or reject an incoming call and / or a call request to the slave unit. I can keep it.

This sub-unit outgoing / incoming call control table sorts the telephone numbers stored in the telephone number column 301, and uses this telephone number as an index to set the destination for which the transfer mode is set for a specific sub-unit. Is easily extracted. In the present example, for example, for the slave unit whose telephone number is 123-0000-3333, the reception of the telephone number of 333-1111-2222 from the other party during the time zone 20:00 to 8:00 is "permitted". The mode is automatically permitted, but reception of an e-mail from an address whose first character string of the e-mail address starts with "badsite" or an address including the character string "@badsite" is set to the "deny" mode. Receiving an e-mail with an attached file containing a character string "badfile" in the file name is also set to "reject" mode, and is automatically rejected. Calls or e-mails from other parties are in the "-" mode (default), and the parent machine is inquired for permission confirmation. Further, as in the case of the slave unit having the telephone number of 123-0000-3334, all unspecified communications can be set to the “deny” mode.
In the following, it is necessary to confirm the transfer to the parent device when there is a call request from the child device, and in the cases where it is not necessary, and to confirm the transfer to the parent device when there is a call request to the child device. The operation of the mobile terminal system will be described for necessary cases and unnecessary cases.

  FIG. 7 is a diagram showing an example of a signal flow in a case where transfer confirmation to the parent device is required when a call is requested from the child device in the portable terminal system according to the present invention. First, in step S101, when there is a call request from the slave unit 102, this call request is transmitted via the base station 104 and the radio control station 105 and processed by the exchange 109. In step S102, exchange 109 searches the handset transmission / reception control table (FIG. 6) in group database 106 based on the telephone number of the call request source (slave). Then, in step S103, it is checked whether or not the parent device confirmation condition is met. When the transfer mode in FIG. 6 is the “−” mode (parent device confirmation is required), in step S104, The telephone number table (FIG. 2) in the group database 106 is searched, and the telephone numbers of the parent devices in the same group are extracted. In step S105, exchange 109 issues a confirmation request to parent device 101 associated with the extracted telephone number.

  Master device 101 receives this confirmation message (message), and inputs permission or prohibition of communication on the screen of FIG. 3B in step S106. When communication permission is input, a permission input message is transmitted from base unit 101 to exchange 109. As a result, in step S107, a connection process is performed from the exchange 109 to the partner device 103 or 108 via the line network 107, and a conversation between the slave device and the partner device becomes possible by establishing a connection. On the other hand, when the communication impossibility is input in master device 101, this is a case of denial of master device transfer. In step S111, an improper input message is transmitted from master device 101 to exchange 109. Done. As a result, in step S113, a report of transfer rejection from the exchange 109 to the slave unit 102 is made. Then, in step S114, the slave unit incoming / outgoing call control table is updated, and in step S115, the connection is disconnected.

  FIG. 8 is a diagram showing an example of a signal flow in a case where transfer confirmation to the parent device is unnecessary when a call is requested from the child device in the portable terminal system according to the present invention. First, in step S201, when there is a call request from the slave unit 102, this call request is transmitted through the base station 104 and the radio control station 105 and processed by the exchange 109. In step S202, the exchange 109 searches the handset transmission / reception control table (FIG. 6) in the group database 106 based on the telephone number of the call request source (handset). Then, in step S203, it is checked whether or not the parent device confirmation condition is met. If the transfer mode in FIG. 6 is the "permission" mode (parent device confirmation unnecessary), in step S204, the partner device 103 or 108 is automatically transmitted. Connection processing is performed. On the other hand, when the transfer mode in FIG. 6 is the “deny” mode (parent device confirmation unnecessary), a transfer denial report is automatically sent to the child device 102 in step S211. Then, in step S212, the slave unit transmission / reception control table is updated, and in step S213, the connection is disconnected.

  FIG. 9 is a diagram showing an example of a signal flow in a case where transfer confirmation to the parent device is required when a call is requested to the child device in the portable terminal system according to the present invention. First, in step S301, when there is a call request from the partner device 103 or 108 to the slave device 102, the call request is transmitted via the line network 107 and processed by the exchange 109. In step S302, exchange 109 searches the handset transmission / reception control table (FIG. 6) in group database 106 based on the telephone number of the call request destination (slave). Then, in step S303, it is checked whether or not the parent device confirmation condition is met. When the transfer mode in FIG. 6 is the "-" mode (parent device confirmation is required), in step S304, the handset number specified by the incoming call is determined. Then, the telephone number table (FIG. 2) in the group database 106 is searched, and the telephone numbers of the parent devices in the same group are extracted. In step S305, exchange 109 issues a confirmation request to parent device 101 associated with the extracted telephone number.

  Master device 101 receives the confirmation message (message), and inputs permission or prohibition of communication on the screen of FIG. 3D in step S306. When communication permission is input, a permission input message is transmitted from base unit 101 to exchange 109. As a result, in step S307, a connection process is performed from the exchange 109 to the slave unit 102 via the wireless control station 105 and the base station 104, and the slave unit and the other party can talk with each other by establishing a connection. On the other hand, if communication failure is input in master device 101, this is a case of denial of master device transfer. In step S311, a failure input message is transmitted from master device 101 to exchange 109, and in step S312, a communication failure input Reception is performed. As a result, in step S113, a report of transfer rejection from the exchange 109 to the other party 103 or 108 is made. Then, in step S314, the slave unit transmission / reception control table is updated, and in step S315, the connection is disconnected.

  FIG. 10 is a diagram showing an example of a signal flow in a case where transfer confirmation to the parent device is unnecessary when a call is requested to the child device in the portable terminal system according to the present invention. First, in step S401, when there is a call request from the partner device 103 or 108 to the slave device 102, the call request is transmitted via the line network 107 and processed by the exchange 109. In step S402, exchange 109 searches the handset transmission / reception control table (FIG. 6) in group database 106 based on the telephone number of the call request destination (slave). Then, in step S403, it is checked whether or not the parent device confirmation condition is met. If the transfer mode in FIG. 6 is the "permitted" mode (parent device confirmation is not required), the transfer to the child device 102 is automatically performed in step S404. Connection processing is performed. On the other hand, when the transfer mode in FIG. 6 is the “deny” mode (parent device confirmation unnecessary), in step S411, a report of transfer rejection is automatically sent to the partner device 103 or 108. Then, in step S412, the slave transmission / reception control table is updated, and in step S413, the connection is disconnected.

  In the above embodiment, the example in which the group database 106 is provided in the exchange 109 has been described. However, the group database 106 may be provided in the base station 104 or the radio control station 105. The group database 106 is connected to a computer (not shown), and writes and reads various data. In particular, data extracted from a telephone directory or an address book can be written in each of the tables shown in FIG. 2 or FIG. 6 using a mobile terminal or a computer (personal computer) connected to the Internet. This computer stores a mobile terminal control program. The portable terminal control program determines, based on the group database 106, whether or not the computer is designated as an automatic permit or an automatic reject at the time of an incoming call or outgoing call request of a slave unit. Is a function for automatically establishing or disconnecting a connection, and if not applicable, a function for transmitting a confirmation message (message) for permitting an incoming or outgoing call of the slave unit to a master unit in the same group, and This is for realizing a function of establishing or disconnecting a connection between the slave unit and the partner unit according to a response message from the master unit. This portable terminal control program can be downloaded to a desired computer via a network, or can be recorded on a computer-readable recording medium and installed on the computer as needed.

  By configuring in this manner, out of a plurality of grouped mobile terminals, outgoing and incoming calls of the mobile terminal are restricted by other mobile terminals, and a call is clearly made to a partner who is known to have no problem in connection. In other words, the connection can be made automatically without intervening operations or time-consuming processing. For example, when grouping multiple mobile terminals belonging to a family member, if the parent has a parent device and the child has a child device, the parent can freely interact with non-problematic people without intervention. In the case of a partner that can be connected and needs to be confirmed, the parent can determine and determine at any time whether or not to permit connection between the slave and the partner. In addition, a usage method that allows only a connection with a specific partner is also possible.

  For example, a parent can suppress the abuse of a portable terminal by a child at home or access to a partner who is unfavorable in terms of morals, and a smooth connection can be established with a partner who is known to have no problem in use. In addition, the present invention can be applied to group and manage the portable terminals of the members in a corporate office or the like. Further, the present invention can be applied as a system for providing a dedicated service to a specific partner.
