Description

  The present invention relates to a communication device using a telephone that transmits and receives signals such as voice signals and data signals between telephones via an exchange owned by a telephone company, and particularly uses a telephone that is suitable when the telephone is a mobile phone. The present invention relates to a communication device. The present invention also relates to a telephone set used in a communication apparatus using the above telephone set.

  Unlike a conventional fixed telephone that is wired to a telephone company switch via a telephone line, the mobile phone is wirelessly connected to the telephone company switch by wireless communication. For this reason, mobile phone users can literally carry the phone literally, and can use it immediately when necessary, and in recent years, mobile phones have rapidly become widespread. In addition to improvements in the performance of components such as liquid crystal display devices and microcomputers that make up mobile phones, miniaturization and cost reductions are also progressing. Mobile phones with functions are becoming popular. For example, mobile phones equipped with a mail function for sending and receiving electronic mail, an Internet function for accessing a desired URL by connecting to the Internet and browsing a Web page, and a game function for playing a computer game are commercially available.

  On the other hand, even when the user is at a place other than his / her home, the mobile phone has the advantage that the user can make a call with the user if he / she calls the mobile phone he / she is carrying. More and more children such as junior high school students have mobile phones. One reason for this is that children often go out at night, such as going to a cram school.

  As mobile phone users are becoming younger, various problems such as excessive use of mobile phones and use of mobile phones in places where they should not be used have arisen. For example, long calls, browsing web pages, frequent sending and receiving of e-mails can increase communication fees, send and receive e-mails during school lessons, There are various problems such as not taking classes seriously.

In view of this, there has been proposed a technique for restricting the use of a mobile phone in a place where use of the mobile phone should be refrained, such as in a train or a hospital (see Patent Document 1 and Patent Document 2). In Patent Document 1, a GPS (global positioning system) device is built in or externally attached to a mobile phone to detect the position of the mobile phone, and when the detected position is a place where the use of the mobile phone should be restricted, A technique is described in which a function control signal is transmitted from a base station to a corresponding mobile phone to limit the function. In Patent Document 2, an output restriction instruction signal is transmitted to a mobile phone in a place where use of the mobile phone is restricted to enter an output restricted state, and the mobile phone that has entered the output restricted state is registered and managed, and registered. A technique is described in which when a managed mobile phone is called, a response message is transmitted to the calling phone indicating that the mobile phone to be called is in a place where use is restricted.
JP 2000-224661 A JP 2000-324539 A

  The above-described technology for restricting the use of a mobile phone is a technology for restricting the use of a mobile phone at a specific location. Therefore, for example, if these techniques are applied to a school premises, it is possible to restrict the use of a mobile phone during class. However, since the mobile phone can be used freely if the user (mobile phone) comes out of the restricted place, the effect of use restriction depending on the place is not so effective.

  Therefore, there is a demand from parents who give children a mobile phone to easily limit the functions of the mobile phone held by their children. Similar requests have been made by companies that have employees have mobile phones for work.

  The processing procedures of the mobile phones A and B and the relay exchange C when calling between the mobile phones, and the processing procedures of the mobile phones A and B and the relay exchange C when executing the e-mail function and the Web page browsing function are known. Same as technology. Therefore, a processing procedure related to function restriction of the mobile phone will be described. In the following description, it is assumed that the mobile phone A is a setting-side telephone that requests setting of function restriction, and the mobile telephone B is a restriction-side telephone that is restricted in function.

  In the first embodiment, the control unit 2 of the setting-side mobile phone A operates as a function restriction request unit, the relay exchange C stores function restriction management data in the hard disk 24, and the control unit 22 operates as a function restriction management unit. The case where the control unit 12 of the restriction side mobile phone B operates as function restriction means will be described.

  First, a function restriction management table 31 that is function restriction management data is recorded in advance on the hard disk 24 of the relay exchange C. FIG. 2 is a schematic diagram illustrating an example of the function restriction management table 31. The function restriction management table 31 includes a telephone number field 32 for the setting side telephone, a telephone number field 33 for the restriction side telephone, a function name field 34 that can be restricted, a setting code number field 35 and a change code number field 36. It consists of and. The restrictable function name column 34 has individual columns for each of the five functions F1 to F5.

  In the first column of the function restriction management table 31 in FIG. 2, the telephone number of the telephone A is written in the telephone number field 32 of the setting side telephone, and the telephone number of the telephone B is written in the telephone number field 33 of the restriction side telephone. Has been written. By writing in this way, the functions of the telephone A to the telephone B can be restricted. In addition, in the function name column 34 that can be restricted, information indicating that the function can be restricted to the three functions F1, F2, and F3 (“◯” in FIG. 2) is written. By writing in this way, the restriction side telephone B can restrict the functions F1 to F3. Further, “1234” is written in the setting code number field 35, and “5678” is written in the change code number field 36. By writing in this way, the password “1234” needs to be input when requesting the function restriction from the setting side telephone A, and the code number “1234” is required when changing or releasing the contents of the function restriction from the restriction side telephone B. 5678 "is required.

  Note that the contents written in the function name column 34 that can be restricted can be changed for each combination of the setting side telephone and the restriction side telephone. For example, in the second column of FIG. 2, “◯” is written as the restrictable function name for the function F4, and in the third column, five functions F1 to F1 as restrictable function names are written. “◯” is written for all of F5.

  On the other hand, a function restriction state table 41 which is function restriction state data is recorded in the memory of the restriction side telephone B. FIG. 3 is a schematic diagram illustrating an example of the function restriction state table 41. The function restriction state table 41 includes a restricted function name field 42 and a restriction content field 43. In the restriction side telephone B, as shown in the first column of the function restriction management table 31 in FIG. 2, the functions F1 to F3 can be restricted. ”,“ F2 ”, and“ F3 ”are written. In the corresponding restriction content column 43, the restriction content is written for each function. For example, when the function F1 is a game function, “function stop” is written, and when the function F2 is a communication charge upper limit regulation function, “communication charge upper limit amount” is written, and the function F3 is an access URL restriction function. If it is, “URL that cannot be accessed” is written. The function of the restriction side telephone B is restricted according to the function restriction state table 41.

  Next, a function restriction setting procedure will be described. FIG. 4 is an explanatory diagram for explaining a procedure when the functions of the mobile phone A to the mobile phone B are restricted. In the following description, the processing performed by the mobile phone A is actually performed by the control unit 2, the processing performed by the mobile phone B is performed by the control unit 12, and the processing performed by the relay exchange C is performed by the control unit 22. .

  In step a1, the user calls the relay switch C by inputting a predetermined code number from the input unit 1 of the mobile phone A, and further operates the input unit 1 to send a function restriction request signal from the mobile phone A to the relay switch C. Send to. The function restriction request signal includes an identification code indicating that it is a function restriction request signal, a telephone number of the mobile phone B, a function name to be restricted, a restriction content, and a setting password. When the function to be restricted is simply switched whether or not the function is to be stopped like a game function, “function stop (OFF)” or “function stop release (ON)” is input as the restriction content. Further, when the function to be restricted is capable of restriction in a plurality of stages such as a communication charge upper limit restricting function, specific contents such as the upper limit amount of the communication charge are input as the restriction contents. The telephone number of the mobile phone A is transmitted from the mobile phone A to the relay switch C when calling the relay switch C.

  In procedure a2, the relay exchange C that has received the function restriction request signal refers to the contents of the function restriction management table 31 shown in FIG. 2 and checks information contained in the function restriction request signal. Specifically, in the relay exchange C, the combination of the telephone number of the setting side telephone A and the telephone number of the restriction side telephone B is written in the function restriction management table 31 and is included in the function restriction request signal. It is checked whether the set password and the setting password written in the function restriction management table 31 match.

  In step a3, it is determined whether or not the function restriction request signal is valid based on the check result. When the combination of the telephone number of the setting side and the restriction side is not written or when the setting code numbers do not match, it is determined that the function restriction request signal is invalid, and the relay exchange C carries the mobile phone in step a4. An error message is sent to telephone A. The mobile phone A displays the received error message on the display unit 3.

  On the other hand, if the combination of the telephone numbers of the setting side and the restriction side is written and the setting passwords match, it is determined that the function restriction request signal is valid, and the relay switch C is determined in step a5. Transmits a function restriction setting signal to the mobile phone B. The function restriction setting signal includes a function name to be restricted and a restriction content. If the mobile phone B cannot be connected due to power-off or the like, a method of retransmitting after a predetermined time or transmitting when the mobile phone B is connected by calling or the like is used.

  In step a6, the cellular phone B that has received the function restriction setting signal writes the received restriction contents in the restriction contents column 43 corresponding to the function name received in the function restriction state table 41. Thereby, the function restriction is set.

  Thereafter, in the procedure a7, the mobile phone B transmits a setting completion signal to the relay exchange C, and in the procedure a8, the relay exchange C transmits a setting completion message to the mobile phone A. The mobile phone A displays the received setting completion message on the display unit 3. This completes the function restriction setting procedure.

  If information regarding function restriction is registered in advance in the relay exchange C as described above, the function of the restriction-side mobile phone B can be easily restricted simply by operating the setting-side mobile phone A. Note that when inputting the function name to be restricted in step a1 and the restriction content, if the fact that the function restriction is to be released is input as the restriction content, the function restriction of the designated function can be released.

As the function to be restricted, all the functions of the restricted mobile phone B can be targeted. For example, the following function restrictions can be considered.
・ Communication charge restriction to set the upper limit of communication charge ・ Telephone charge restriction to set the upper limit of telephone charge ・ Packet communication charge restriction to set the upper limit of packet communication charge ・ Access URL restriction to restrict accessible URL ・ Receive Incoming call restriction that restricts destinations that can be used, call destination restriction that restricts call destinations, call time restriction that restricts call time, use time zone restriction that restricts the time zone in which a mobile phone can be used, execution of computer games If the game restriction / restriction-side mobile phone B that restricts the function is provided with a function for restricting the functions of other mobile phones as the setting-side telephone, this function restriction function can be restricted.

According to the above embodiment, the following effects can be obtained.
(1) In the above embodiment, if information related to function restriction is registered in the relay exchange C in advance, the function of the restriction-side mobile phone B can be easily restricted simply by operating the setting-side mobile phone A. . Therefore, for example, when the parent gives the child a mobile phone, the parent can operate his / her mobile phone to limit the functions of the child's mobile phone. As a result, even younger children can use the mobile phone with confidence.

  (2) In the above embodiment, when setting the function restriction, it is necessary to input the setting code number, so that it is possible to prevent an unrelated third party from setting and releasing the function restriction easily. Further, even in an environment where the user of the restriction side mobile phone B can operate the setting side mobile phone A, the function restriction cannot be released unless the password is known, so that the function restriction can be made to function effectively.

  (3) If a mobile phone is lost, register the lost mobile phone as a restricted phone and restrict the mobile phone so that it cannot be used for all hours, for example 24 hours. It is possible to prevent others from seeing information that is used for mobile phone or stored in a mobile phone.

  (4) When a person unfamiliar with the operation of a mobile phone wants to set or cancel the function restriction of his / her mobile phone, he / she asks a person familiar with the operation to restrict the function of his / her mobile phone from the mobile phone owned by that person Can be set / released. For example, it becomes possible to set / cancel function restrictions on a mobile phone held by an elderly parent from a mobile phone held by a child. In this case, if the incoming call restriction that restricts the destination of the incoming call is set, it is possible to prevent a mischievous telephone call and to eliminate a so-called transfer fraud call that has recently occurred frequently.

In addition, you may change the said embodiment as follows.
-It may be possible to set / cancel the function restriction without using the setting password. In this case, it is possible to easily set / cancel the function restriction, and to prevent the user from forgetting the password and cannot set / cancel the function restriction. In this case, it is preferable that the user of the setting side mobile phone A manages the user of the restriction side mobile phone B or an unrelated third party so that the setting side mobile phone A cannot be easily operated.

  -When setting the function restriction of the restriction side mobile phone B from the setting side mobile telephone A, the restriction side mobile phone B may be configured to reject the function restriction setting. In this case, it is possible to prevent the user of the setting-side mobile phone A from unilaterally restricting the function of the restriction-side mobile phone B, and to restrict the function reflecting the intention of the user of the restriction-side mobile phone B. be able to.

  FIG. 5 is an explanatory diagram for explaining a procedure for rejecting the function restriction setting from the restriction-side mobile phone B at the time of function restriction setting. Since steps a1 to a5 are the same as those in FIG. 4, the same reference numerals are given and description thereof is omitted.

  When the function restriction setting signal is transmitted from the relay exchange C to the restriction side mobile phone B, the restriction side telephone B displays the function name restricted and the content of restriction on the display unit 13 in step a9. In step a10, the user of the restricted telephone set B looks at the display content and determines whether to agree or reject the function restriction, and inputs the determination result from the input unit 11.

  When it is input in step a10 that function restriction is rejected, in step a11, the restriction side telephone B transmits a rejection signal to the relay exchange C. In step a12, the relay exchange C rejects the setting to the setting side telephone A. Send a message. The cellular phone A displays the received setting rejection message on the display unit 3. As a result, the function restriction setting is rejected.

  On the other hand, when it is input in step a10 that the function restriction is agreed, in step a13, the mobile phone B corresponds to the received function name in the function restriction state table 41 based on the received function restriction setting signal. The received restriction content is written in the restriction content column 43. Thereby, the function restriction is set.

  Thereafter, in the procedure a14, the mobile phone B transmits a setting completion signal to the relay exchange C, and in the procedure a15, the relay exchange C transmits a setting completion message to the mobile phone A. The mobile phone A displays the received setting completion message on the display unit 3. This completes the function restriction setting procedure.

  The restriction content of the function restriction set by the setting-side mobile phone A may be configured to be changed from the restriction-side mobile phone B. Also in this case, similarly to the case where the setting of the function restriction is rejected, the user of the setting side mobile phone A can be prevented from unilaterally restricting the function of the restriction side mobile phone B, and the restriction side mobile phone B can be prevented. It is possible to perform functional restrictions reflecting the intentions of users. It should be noted that if the restriction content to be changed is requested to be released, the function restriction can be released.

  FIG. 6 is an explanatory diagram for explaining a procedure when the restriction content of the function restriction is changed from the restriction-side mobile phone B. In step a21, the user calls the relay switch C by inputting a predetermined code number from the input unit 11 of the mobile phone B, and further operates the input unit 11 to send a change request signal from the mobile phone B to the relay switch C. Send. The change request signal includes an identification code indicating that it is a change request signal, a phone number of the mobile phone A, a phone number of the mobile phone B, a restricted function name, a changed restriction, and a change password. include.

  In step a22, the relay exchange C that has received the change request signal refers to the contents of the function restriction management table 31 shown in FIG. 2 and checks information included in the change request signal. Specifically, in the relay exchange C, the combination of the telephone number of the setting-side mobile phone A and the telephone number of the restriction-side mobile phone B is written in the function restriction management table 31 and is included in the change request signal. It is checked whether or not the changed password number and the changed password written in the function restriction management table 31 match.

  In step a23, it is determined whether or not the change request signal is valid based on the check result. When the combination of the telephone number of the setting side and the restriction side is not written or the passwords do not match, it is determined that the change request signal is invalid, and the relay exchange C sends the cellular phone B to the mobile phone B in step a24. Send an error message. The mobile phone B displays the received error message on the display unit 13.

  On the other hand, if the combination of the telephone number of the setting side and the restriction side is written and the passwords for change match, it is determined that the change request signal is valid, and the relay exchange C determines in step a25 that A function restriction setting signal is transmitted to the mobile phone B. The function restriction setting signal includes the function name to be restricted included in the change request signal and the restriction contents after the change.

  In step a26, the cellular phone B that has received the function restriction setting signal rewrites the contents of the restriction contents column 43 corresponding to the received function name in the function restriction state table 41 with the received restriction contents. Thereby, the restriction content of the function restriction is changed.

  Thereafter, in the procedure a27, the mobile phone B transmits a change completion signal to the relay exchange C, and in the procedure a28, the relay exchange C transmits a change completion message to the mobile phone A. The mobile phone A displays the received change completion message on the display unit 3. This completes the procedure for changing the restriction content of the function restriction.

  The restriction content of the function restriction set by the setting-side mobile phone A can be changed from the restriction-side mobile phone B, and can be changed without approval from the setting-side mobile phone A when changing. May be. Also in this case, similarly to the case where the setting of the function restriction is rejected, the user of the setting side mobile phone A can be prevented from unilaterally restricting the function of the restriction side mobile phone B, and the restriction side mobile phone B can be prevented. It is possible to perform functional restrictions reflecting the intentions of users. Moreover, since the change from the restriction content requires approval from the setting-side mobile phone A, it is possible to prevent an easy change. It should be noted that if the restriction content to be changed is requested to be released, the function restriction can be released.

  FIG. 7 is an explanatory diagram for explaining a procedure when the restriction content of the function restriction is changed from the restriction-side mobile phone B. In step a31, the user calls the relay switch C by inputting a predetermined code number from the input unit 11 of the mobile phone B, and further operates the input unit 11 to send a change request signal from the mobile phone B to the relay switch C. Send.

  In procedure a32, the relay exchange C that has received the change request signal refers to the contents of the function restriction management table 31 shown in FIG. 2 and checks information included in the change request signal. Specifically, in the relay exchange C, the combination of the telephone number of the setting-side mobile phone A and the telephone number of the restriction-side mobile phone B is written in the function restriction management table 31 and is included in the change request signal. It is checked whether or not the changed password number and the changed password written in the function restriction management table 31 match.

  In procedure a33, it is determined whether or not the change request signal is valid based on the check result. If the combination of the telephone number of the setting side and the restriction side is not written, or if the password for change does not match, it is determined that the change request signal is invalid, and the relay exchange C uses the mobile phone in step a34. Send an error message to B. The mobile phone B displays the received error message on the display unit 13.

  On the other hand, if the combination of the telephone number of the setting side and the restriction side is written and the passwords for change match, it is determined that the change request signal is valid, and the relay exchange C determines in step a35. A function restriction change message is transmitted to the mobile phone A indicating that a change in the restriction contents of the function restriction is requested. The function restriction change message includes the restricted function name and the restriction contents after the change.

  In step a36, the setting-side mobile phone A displays the received function restriction change message on the display unit 3. In step a <b> 37, the user of the setting-side mobile phone A determines whether to approve or reject the change of the restriction content of the function restriction by looking at the display content, and inputs the determination result from the input unit 1.

  When it is input in step a37 that the change is rejected, in step a38, the setting-side mobile phone A transmits a change rejection signal to the relay exchange C, and in step a39, the relay exchange C transmits to the restriction-side mobile phone B. Send a change rejection message. The restriction side mobile phone B displays the received change rejection message on the display unit 13. Thus, the change of the restriction content of the function restriction is rejected.

  On the other hand, when it is input in step a37 that the change is agreed, in step a40, the setting-side mobile phone A transmits a change approval signal to the relay exchange C, and in step a41, the relay exchange C sends the restriction-side mobile phone. A function restriction setting signal is transmitted to B. The function restriction setting signal includes the function name to be restricted included in the change request signal and the restriction contents after the change.

  In step a42, the cellular phone B that has received the function restriction setting signal rewrites the contents of the restriction contents column 43 corresponding to the received function name in the function restriction state table 41 with the received restriction contents. Thereby, the restriction content of the function restriction is changed.

  Thereafter, in step a43, the mobile phone B transmits a change completion signal to the relay exchange C, and in step a44, the relay exchange C transmits a change completion message to the mobile phone A. The mobile phone A displays the received change completion message on the display unit 3. This completes the procedure for changing the restriction content of the function restriction.

Specifically, in the relay exchange C, the combination of the telephone number of the setting-side mobile phone A and the telephone number of the restriction-side mobile phone B is written in the function restriction management table 31 and is included in the change request signal. It is checked whether or not the changed password number and the changed password written in the function restriction management table 31 match.

  In step b33, it is determined whether or not the change request signal is valid based on the check result. If the combination of the setting side and the restriction side telephone number is not written or the change passwords do not match, it is determined that the change request signal is invalid, and the relay exchange C determines in step b34 that the mobile phone Send an error message to B. The mobile phone B displays the received error message on the display unit 13.

  On the other hand, if the combination of the telephone number of the setting side and the restriction side is written and the change passwords match, it is determined that the change request signal is valid, and the relay exchange C determines in step b35 that the change request signal is valid. A function restriction change message is transmitted to the mobile phone A indicating that a change in restriction contents for the restricted function is requested. The function restriction change message includes the restricted function name and the restriction contents after the change.

  In step b36, the setting-side mobile phone A displays the received function restriction change message on the display unit 3. In step b <b> 37, the user of the setting-side mobile phone A determines whether to approve or reject the change to the restriction content of the function restriction by looking at the display content, and inputs the determination result from the input unit 1.

  When it is input in step b37 that the change is rejected, in step b38, the setting-side mobile phone A transmits a change rejection signal to the relay exchange C, and in step b39, the relay exchange C transmits to the restriction-side mobile phone B. Send a change rejection message. The restriction side mobile phone B displays the received change rejection message on the display unit 13. Thus, the change of the restriction content of the function restriction is rejected.

  On the other hand, if it is input in step b37 that the change is agreed, in step b40, the setting-side mobile phone A transmits a change approval signal to the relay exchange C. In step b41, the relay exchange C receives the change first. Based on the changed request signal, the contents of the restriction contents column 43 corresponding to the received function name in the function restriction state table 41 are rewritten with the received restriction contents.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of the communication apparatus is the same as that in FIG. 1, detailed description thereof is omitted. In the third embodiment, the control unit 2 of the setting-side mobile phone A operates as a function restriction request unit, and a function restriction management table 31 that is function restriction management data is stored in the memory 14 of the restriction-side mobile phone B. A case where the control unit 12 operates as a function limiting unit will be described.

  First, a function restriction management table 31 is stored in advance in the memory 14 of the mobile phone B. The configuration of the function restriction management table 31 is the same as that shown in FIG. 2, but information is usually stored only in the first column. This is because the number of setting side telephones is usually one, and when there are two or more setting side telephones, information is also stored in the second and subsequent columns. The memory 14 of the mobile phone B stores a function restriction state table 41. Since the configuration of the function restriction state table 41 is the same as that in FIG. 3, detailed description thereof is omitted.

  Next, a function restriction setting procedure will be described. FIG. 12 is an explanatory diagram for explaining a procedure when the functions of the mobile phone A to the mobile phone B are restricted. In the following description, the processing performed by the mobile phone A is actually performed by the control unit 2, the processing performed by the mobile phone B is performed by the control unit 12, and the processing performed by the relay exchange C is performed by the control unit 22. .

  First, in step c1, the function restriction management table 31 is registered in the memory 14 of the mobile phone B in advance. This registration is preferably performed by the user of the mobile phone A. This is because if the setting code number is known to the user of the mobile phone B, the code number does not make sense.

  In step c2, the user inputs the telephone number of the mobile phone B from the input unit 1 of the mobile phone A, calls the mobile phone B via the relay exchange C, and further operates the input unit 1 to restrict the function from the mobile phone A. A request signal is transmitted to the relay exchange C. The function restriction request signal includes an identification code indicating that it is a function restriction request signal, a telephone number of the mobile phone B, a function name to be restricted, a restriction content, and a setting password.

In step c10, the relay exchange C transmits a setting completion message to the mobile phone A as it is. The mobile phone A displays the received setting completion message on the display unit 3. This completes the function restriction setting procedure.

  If information related to function restriction is registered in advance in the restriction-side mobile phone B in this way, the function of the restriction-side mobile phone B can be easily restricted simply by operating the setting-side mobile phone A. Note that when inputting the function name to be restricted in step c2 and the restriction content, if the fact that the function restriction is to be released is input as the restriction content, the function restriction of the designated function can be released. In the third embodiment, the same effect as in the first embodiment can be obtained.

In addition, you may change this embodiment as follows.
-It may be possible to set / cancel the function restriction without using the setting password. In this case, the function restriction setting / releasing operation is facilitated, and it is possible to prevent the setting code from being forgotten because the setting code is forgotten. In this case, it is preferable that the user of the setting side mobile phone A manages the user of the restriction side mobile phone B or an unrelated third party so that the setting side mobile phone A cannot be easily operated.

  -When setting the function restriction of the restriction side mobile phone B from the setting side mobile telephone A, the restriction side mobile phone B may be configured to reject the function restriction setting.
