[Problems to be solved by the invention]
By the way, the unique telephone number of the mobile phone terminal can be called personal information of the user of the terminal. Therefore, there are many cases where the user does not want to tell the unique telephone number of his / her mobile phone terminal even when he / she wants to communicate with others using the mobile phone terminal. In other words, it is easy to give a unique phone number to other friends who can be trusted, but for example, if you are an unreliable person, or just want to contact you temporarily or short-term, etc. Often, you don't want to tell your phone number. This is because if a unique telephone number is given to an unreliable person or a person who wants to contact only temporarily or in a short period of time, the unique telephone number may be misused thereafter.
[0006]
In addition, for example, when a ticket seller sells a ticket by telephone reservation or the like, in general, a telephone number dedicated for reservation is issued from a telecommunications carrier, and the telephone number dedicated for reservation is sent to a media such as a newspaper or television. This is done to inform an unspecified number of users. In this case, for example, even if a number of mischievous calls is made to the reservation dedicated telephone number, it cannot be easily changed to another telephone number in order to maintain the ticket reservation sales service.
[0007]
The present invention has been made in view of such a problem, and makes it easy to communicate with another person without revealing terminal-specific identification information, and a problem caused by incoming calls from an unspecified number of users.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 shows a network configuration example of a mobile communication system (a mobile phone system of the present embodiment) which is an example of a communication system of the present invention.
[0017]
The mobile phone system shown in FIG. 1 is roughly divided into a mobile communication terminal (in this embodiment, mobile phone terminals 61 and 62) which is an example of the communication apparatus of the present invention, and an example of the communication management apparatus of the present invention. It comprises a certain provider database device 70 and a mobile communication network 65 which is a predetermined communication network of the present invention.
[0018]
The mobile communication network 65 includes exchanges 66 and 67, an HLR (Home Location Register) 68, and a VLR (Visitor Location Register) 69. In the case of the present embodiment, the provider database device 70 also includes the mobile communication. It is included in the net 65. The exchange 66 is connected to the base station 63, and the exchange 67 is connected to the base station 64. The provider database device 70 may be provided outside the mobile communication network 65. The exchanges 66 and 67, the HLR 68, the VLR 69, and the like are provided in a general mobile phone system, and a description thereof is omitted. Hereinafter, the mobile phone terminal 61 of FIG. 1 is a user A terminal (referred to as a user A terminal 61), and the mobile phone terminal 62 is referred to as a user B terminal (referred to as a user B terminal 62). To do.
[0019]
Here, the mobile phone system according to the embodiment of the present invention is different from the unique identification information (unique phone number) originally assigned to the user's mobile phone terminal, for example, upon request from the user. Identification information (hereinafter referred to as sub-identification information) that can be used only when making a call from a specific mobile phone terminal can be issued. That is, for example, when the sub-identification information that can be used only when the user B terminal 62 makes a call to the user A terminal 61 is issued, the mobile phone system of the present embodiment has the user B terminal 62 The communication line between the user B terminal 62 and the user A terminal 61 is connected only when a call is made to the user A terminal 61 using the sub-identification information. Therefore, for example, even if another user C's mobile phone terminal (denoted as user C terminal) makes a call to the user A terminal 61 using the sub-identification information, the mobile phone according to the present embodiment is used. The telephone system rejects the call from the user C terminal and prevents the communication line from being connected.
[0020]
In the present invention, the sub-identification information includes, for example, not only numbers (phone numbers) made up of a plurality of numeric strings but also a combination of a plurality of characters (including so-called pictograms), symbols, numbers, and the like as appropriate. Any of image, audio information, etc. that can be distinguished from others may be used. Further, the expiration date of the sub-identification information may be set to infinite or finite, and the expiration date may be continued until a request for cancellation of the identification information is received from the user. After the sub-identification information is invalidated due to the expiration date, or the validity is revoked by a cancellation request from the user, for example, the user B terminal 62 transmits to the user A terminal 61 using the sub-identification information. Even if the mobile phone system is performed, the mobile phone system rejects the call from the user B terminal 62 and does not connect the communication line. In addition, how to set the expiration date, for example, is determined by the user's will when using the issuance service of the sub-identification information, or the expiration date is determined in advance at the time of new subscription of the issuance service Such a method can be considered. Further, when the sub-identification information is invalidated, the fact is notified to the user.
[0021]
As described above, according to the mobile phone system of the present embodiment, the sub-identification information different from the terminal-specific identification information (unique phone number) can be used. For example, for those who are not necessarily reliable or who want to contact only temporarily or in the short term, only the sub-identification information is given without giving the unique identification information. In addition to being able to contact only for a period of time, it is possible to prevent misuse of unique identification information that is personal information. In addition, since the sub-identification information is information that can be set with a finite expiration date or can be canceled arbitrarily by the user, even if the sub-identification information is misused, the user can minimize damage. Can be stopped. In particular, since the sub-identification information is used only between the terminal of the user who requested the issuance and the terminal of the user permitted to use the sub-identification information, for example, the sub-identification information is provided to an unspecified number of people. Even if it is known, others cannot use the sub-identification information, and for example, even if the same sub-identification information exists, it does not lead to the wrong partner. Therefore, the issuer side of the sub-identification information can easily accept the request for issuing the sub-identification information, and the requester side can easily request the issue of the sub-identification information.
[0022]
Hereinafter, as an example of the sub-identification information, a telephone number (denoted as a temporary telephone number) whose validity period is set to a certain period is given, and the user A terminal 61 is used after the temporary telephone number is issued. A flow until the communication line is connected to the user B terminal 62 will be described.
[0023]
The temporary telephone number issuance procedure is roughly classified by a business operator (a business operator that provides a mobile phone service, in the case of FIG. 1, a business operator database device 70) in response to a request from a user. A procedure for issuing a telephone number (first embodiment) and a procedure for determining whether or not a user voluntarily issues a temporary telephone number and the operator permits registration of the temporary telephone number. (Second Embodiment) can be considered.
[0024]
[First Embodiment]
First, a first embodiment of the present invention will be described with reference to FIGS.
[0025]
FIG. 2 shows that the operator database device 70 issues a temporary telephone number that can be used only when the user B terminal 62 makes a call to the user A terminal 61 in response to a request from the user A terminal 61. The flow until the communication line is connected by the user B terminal 62 making a call to the user A terminal using the temporary telephone number is shown.
[0026]
In FIG. 2, first, as a procedure P <b> 1, a temporary telephone number issuance request and information on the unique telephone number of the terminal are sent from the user A terminal 61 to the provider database device 70.
[0027]
Upon receiving the issuance request from the user A terminal 61, the provider database device 70 generates a temporary telephone number and a random number associated therewith as procedure P2, and notifies the user A terminal 61 of such information. . The business entity database device 70 registers the temporary telephone number and random number in the table in association with the unique telephone number of the user A terminal 61 (registers in the correspondence table). Note that the temporary telephone number issued by the provider database device 70 is a telephone number that does not overlap with the unique telephone number of each mobile phone terminal already on the market, and the random number is stored in the provider database device 70. Automatically generated by a random number generator. In particular, in the case of the present embodiment, the provider database device 70 may issue the same temporary telephone number to a plurality of mobile phone terminals at the same time or at different times. Each random number issued at the same time has a different value. Further, the provider database device 70 is notified from the other provider database device 71 of the unique telephone number issued by another mobile phone system other than the mobile phone system to which it belongs.
[0028]
It should be noted that the user A terminal 61 issues a temporary telephone number issuance request or notification of a unique telephone number to the business entity database device 70, or a temporary telephone number or random number from the business operator database device 70 to the user A terminal 61. For the notification, any method such as contact by words using a cellular phone line or contact by facsimile, contact by e-mail, communication by communication via the Internet may be used.
[0029]
Next, as the procedure P3, the temporary telephone number and the random number are notified from the user A terminal 61 to the user B terminal 62. In the case of the present embodiment, the user A terminal 61 uses the notification means by short-range wireless communication such as wireless communication using infrared rays or so-called Bluetooth wireless communication, for example, so that the user B terminal 61 62 is notified of the temporary telephone number and random number. The notification of the temporary telephone number and the random number is made by the verbal or written notification between the user A and the user B, or the temporary telephone number displayed on the display of the user A terminal 61. Notification such as showing to B may be used.
[0030]
The user B terminal 62 informed of the temporary telephone number and the random number determines whether or not there is a problem with the temporary telephone number, and when there is no problem, as the procedure P4, the user B terminal 62 is determined. The unique telephone number and the random number information are transmitted to the provider database device 70. When determining whether there is no problem with the temporary telephone number, the user B terminal 62 searches for a telephone number registered in the telephone directory in the terminal itself, for example, and is the same as the temporary telephone number. If the telephone number is already registered in the phone book, it is determined that there is a problem, and if it is not registered, it is determined that there is no problem. Of course, for example, the user B may determine whether or not there is a problem with the temporary telephone number by checking the telephone book number in the terminal.
[0031]
Upon receiving the unique telephone number and random number of the user B terminal 62, the business entity database device 70 confirms that the terminal that sent the random number is not the user A terminal 61 based on the information of the unique telephone number. At the same time, it is searched whether or not the random number sent from the user B terminal 62 is registered in the internal correspondence table (whether there is a matching random number). In the case of the present embodiment, the random number sent from the user B terminal 62 is the same as the random number previously issued to the user A terminal 61 and is already registered in the internal correspondence table. Yes. Accordingly, in this case, the provider database device 70 searches the temporary telephone number corresponding to the random number and the unique telephone number of the user A terminal 61 from the correspondence table. As a result, the provider database device 70 recognizes (consistency is recognized) that the user B terminal 62 is a terminal for which the temporary telephone number is legally notified from the user A terminal 61. Then, the provider database device 70 registers the temporary telephone number so that the user B terminal 62 can use it in the mobile communication network 65. Further, at this time, the business entity database device 70 includes a correspondence table of the temporary telephone number and random number and the unique telephone number of the user A terminal 61, and the temporary telephone number and the unique telephone number of the user B terminal 62. Add the association and register settings. When the random number sent from the user B terminal 62 is not retrieved from the correspondence table (there is no matching random number), the business entity database device 70 sends the random number to the user B terminal 62. To the effect, and the permission to use the temporary telephone number in the mobile communication network 65 is not given.
[0032]
The notification of the unique telephone number or random number from the user B terminal 62 to the business entity database device 70 is, for example, by word communication or facsimile communication using a mobile phone line, by e-mail, or communication via the Internet. Any method such as communication may be used.
[0033]
Next, as procedure P5, for example, it is assumed that a call is made from the user B terminal 62 using the temporary telephone number. At this time, the mobile communication network 65 receives the temporary telephone number as the telephone number of the caller, together with the unique telephone number of the user B terminal 62 indicating the caller. At this time, the mobile communication network 65 detects that the temporary telephone number, which is the telephone number of the callee, does not correspond to any of the unique telephone numbers of other mobile phone terminals.
[0034]
In this case, as the procedure P6, the mobile communication network 65 inquires the business operator database device 70 about the validity of the temporary telephone number, and obtains information on the unique telephone number and temporary telephone number of the user B terminal 62, To the user database device 70. At this time, the provider database device 70 has registered in the correspondence table the unique telephone number of the user B terminal 62 that has received an inquiry from the mobile communication network 65 and the unique telephone number corresponding to the temporary telephone number. Search for no. In the case of the present embodiment, as described above, the correspondence table includes the correspondence between the temporary telephone number and the user A terminal 61, and the unique telephone of the temporary telephone number and the user B terminal 62. Since the association with the number has already been registered, the provider database device 70 recognizes that the temporary telephone number is a number notified only to the user B terminal 62 from the user A terminal 61. Then, the business entity database device 70 informs the mobile communication network 65 that the temporary telephone number is a valid number, and the unique telephone of the user A terminal 61 to which the temporary telephone number is issued. Give the number. In this way, the mobile communication network 65 that received the temporary phone number is valid and the corresponding unique phone number is received as a procedure P7 to the user A terminal based on the unique phone number. I do. As described above, the user B terminal 62 can communicate with the user A terminal 61.
[0035]
According to the present embodiment, as described above, the correspondence table in the provider database device 70 includes the correspondence between the temporary telephone number and the unique telephone number of the user A terminal 61 and the temporary telephone number. Correspondence between the target telephone number and the unique telephone number of the user B terminal 62 is registered. For this reason, for example, even if there are a plurality of other temporary telephone numbers that are exactly the same as the temporary telephone numbers used between the user A terminal 61 and the user B terminal 62, the provider database device 70 searches the correspondence table based on the unique telephone number and temporary telephone number of the user B terminal 62 sent from the mobile communication network 65 during the procedure P6. The unique telephone number of the user A terminal 61 can be transmitted to the mobile communication network 65 without making a mistake with the mobile phone terminal.
[0036]
FIG. 3 shows a detailed processing flow until the provider database device 70 issues a temporary telephone number and a random number in response to a request from the user A terminal 61.
[0037]

[0038]
When proceeding to the process of step S2, the business entity database device 70 searches for a unique telephone number of the user A terminal 61 from a plurality of unique telephone number information registered in advance inside, and at step S3, Determination of whether or not the unique telephone number of the user A terminal 61 has already been registered, that is, the user A terminal 61 is a subscriber terminal of the mobile phone system and the temporary telephone number providing service according to the present invention. It is determined whether the terminal is a legitimate subscriber terminal. If the provider database device 70 determines that the subscriber terminal is not a subscriber terminal in step S3, the provider database device 70 proceeds to the processing of step S5, and notifies the user A terminal 61 that the temporary telephone number is refused to be issued. I do. On the other hand, when it determines with it being a subscriber terminal in step S3, the provider database apparatus 70 advances a process to the following step S4.
[0039]
When the processing proceeds to step S4, the business entity database device 70 generates a temporary telephone number and a random number associated therewith, notifies the user A terminal 61 of the information, and also transmits the temporary telephone number and random number. It is registered in the correspondence table in association with the unique telephone number of the user A terminal 61.
[0040]
FIG. 4 shows the flow of processing until the provider database device 70 gives the user B terminal 62 permission to use a temporary telephone number.
[0041]
In FIG. 4, the provider database device 70 is in a signal reception waiting state in step S11. As described above, when receiving the unique telephone number and random number information from the user B terminal 62, for example, The process proceeds to step S12.
[0042]
When the processing proceeds to step S12, the business entity database device 70 starts a random number search with reference to the correspondence table described above, and the random number sent from the user B terminal 62 is registered in the correspondence table in step S13. Judge whether or not. That is, in the provider database device 70, the random number sent from the user B terminal 62 is the same as the random number that has already been issued to another mobile phone terminal (in this case, the user A terminal 61). Judgment is made. If the business entity database device 70 determines in step S13 that the random number is not registered in the correspondence table, the business operator database device 70 proceeds to the process of step S15 and uses the temporary telephone number for the user B terminal 62. Notify that permission is not granted. On the other hand, when it determines with the random number having been registered into the corresponding table in step S13, the provider database apparatus 70 advances the process to the next step S14.
[0043]
When the processing proceeds to step S 14, the business entity database device 70 adds the temporary telephone number and the unique telephone number of the user B terminal 62 to the correspondence table of the temporary telephone number and the unique telephone number of the user A terminal 61. By adding the correspondence information with the number, use permission of the temporary telephone number by the user B terminal 62 is given. In this case, the operator database device 70 notifies the user B terminal 62 that the temporary telephone number is permitted, and the user A terminal 61 also temporarily notifies the user B terminal 62. Notify that the phone number has been used.
[0044]
FIG. 5 shows the flow of processing performed between the mobile communication network 65 and the provider database device 70 when there is a call from a mobile phone terminal using a temporary telephone number.
[0045]

The unique telephone number of the terminal is transmitted to the provider database device 70.
[0046]
Upon receiving the temporary telephone number and the unique telephone number, the business entity database device 70 registers correspondence information between the unique telephone number of the caller terminal and the temporary telephone number with reference to the correspondence table in step S51. In step S52, it is determined whether or not communication by the temporary telephone number is permitted based on the search result. When it determines with not permitting communication in step S52, the provider database apparatus 70 notifies the mobile communication network 65 to reject transmission in step S55.
[0047]
On the other hand, when it is determined in step S52 that the communication is permitted, the provider database device 70 permits the outgoing call and the unique telephone number of the receiver terminal (user A terminal 61 in the present embodiment) in step S53. Is sent to the mobile communication network 65. Receiving this, the mobile communication network 65 connects a communication line between the caller terminal and the callee terminal. In addition, the mobile communication network 65 notifies the provider database device 70 that the communication service using the temporary telephone number has started in step S54.
[0048]
[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
[0049]
FIG. 6 shows that the user A terminal 61 voluntarily issues a temporary telephone number that can be used only when the user B terminal 62 makes a call to the user A terminal 61, and the operator database device 70 temporarily Whether or not to permit registration of the target telephone number, and if permitted, the user B terminal 62 uses the temporary telephone number to make a call to the user A terminal, thereby connecting the communication line. It represents the flow up to.
[0050]
In FIG. 6, as a procedure P <b> 11, the user A terminal 61 first issues a temporary telephone number and a random number Ra (first random number), and uses the information on the temporary telephone number and the random number Ra as the user B terminal 62. Notify In this case, as in the first embodiment, the user A terminal 61 uses the short-distance wireless communication such as infrared or Bluetooth, or the notification means such as verbal or document, for example, the temporary telephone number and the random number Ra. Is sent to the user B terminal 62. In this case, the temporary telephone number may be determined arbitrarily by the user A himself or may be automatically generated by the user A terminal 61, for example. The random number Ra is automatically generated by a random number generator or the like possessed by the user A terminal 61.
[0051]
The user B terminal 62 informed of the temporary telephone number and the random number Ra determines whether or not there is a problem with the temporary telephone number. If there is no problem, the user B terminal 62 performs step P12 as the user B terminal. Information on the random number Rb (second random number) generated by 62 is notified to the user A terminal 61. In this case, as in the first embodiment, the user B terminal 62 searches for whether the temporary telephone number is the same as the telephone number registered in the telephone book in the own terminal, for example. To determine whether the temporary telephone number is satisfactory. In addition, when the random number Rb is notified from the user B terminal 62 to the user A terminal, the short-range wireless communication, the verbal or document notification means is used. The random number Rb is automatically generated by a random number generator or the like that the user B terminal 62 has.

And whether the random number Ra sent from the user A terminal 61 and the random number Ra sent from the user B terminal 62 coincide with each other, similarly, the random number Rb and the random number Rb coincide with each other. It is determined whether or not. If any one of these random numbers does not match, the provider database device 70 does not permit the temporary telephone number to be issued, and informs the user A terminal 61 and the user B terminal 62 of that fact. . On the other hand, when it is determined that the random numbers Ra and Rb match each other, the business entity database device 70 receives the temporary telephone number sent from the user A terminal 61 from the user A terminal 61. It is recognized that the information has been properly notified to the terminal 62.
[0055]
Further, as in the case of the first embodiment described above, the provider database device 70 is a telephone number whose temporary telephone number does not overlap with the unique telephone number of each mobile phone terminal already on the market. And whether it is a number that you do not want to use, that is, whether it is a valid temporary phone number. In P15, the user A terminal 61 and the user B terminal 62 are notified that use of the temporary telephone number is not permitted. The provider database device 70 matches the temporary telephone number sent from the user A terminal 61 when the temporary telephone number is already registered, or does not want to be used for some reason. In such a case, the user A terminal 61 and the user B terminal 62 may be notified that the use of the temporary telephone number is not permitted.
[0056]
On the other hand, when it is determined that the temporary telephone number does not overlap (is valid) with another unique telephone number or the like, the provider database device 70 uses the temporary telephone number as the mobile communication network 65 by the user B terminal 62. Set it to be available within. In other words, the provider database device 70 in this case associates the temporary telephone number with the unique telephone number of the user A terminal 61, and the temporary telephone number and the unique telephone number of the user B terminal 62.
