Description

  The present invention relates to a communication system through, for example, a mobile phone system, a PHS (Personal Handyphone System), and a wired network.

  As is well known, in the fixed telephone and the mobile telephone, the caller number assigned to the caller terminal is notified to the callee terminal. In the receiving terminal, a caller number and a name are associated with each other in advance and stored as phonebook data. The caller number notified at the time of incoming call is compared with the above phonebook data, and the corresponding name is displayed on the display unit. It is displayed and the user is notified of who the caller is.

  However, even if the calling terminal is lent to a third party other than the owner and used, the third party's name is not displayed on the receiving terminal, and the caller ID of the calling terminal or calling The owner name of the side terminal is displayed (however, when the telephone directory data is registered for the calling side terminal in the receiving side terminal), the receiving side cannot recognize the true caller.

  On the other hand, conventionally, an ID center is provided in the system, and the subscriber ID is registered instead of the number (sender number) assigned to the terminal. Then, by connecting to the ID center by calling a special number and making a call to a desired partner through the ID center, information for identifying the caller is notified to the receiving terminal (for example, see Patent Document 1).

However, this method has a problem that it is necessary for the calling user to store the subscriber ID, and there is a problem that only the information specifying the caller can be notified to the receiving side, and the convenience is low.
JP 2000-083097 A

  In conventional communication systems, when notifying the callee of information identifying the caller, there is a problem that the calling user needs to store the subscriber ID, and only the information specifying the caller is notified to the callee. There was a problem that it was not possible, and convenience was low.

  The present invention can notify the callee terminal of information specifying the caller without giving a large load to the network, and can also notify the identification information of the terminal that made the call, An object of the present invention is to provide a communication system and a communication terminal device that are highly convenient.

  In order to achieve the above-described object, the present invention accommodates a plurality of communication terminal devices through a network, and the first communication terminal device designates a first communication terminal device that has made a transmission request. In a communication system including a connection device that is exchange-connected to a communication terminal device, the first communication terminal device includes an input unit that inputs encrypted information including caller identification information for identifying the caller and a password. A password input means for accepting input of a password, a notification means for notifying that a transmission cannot be made when the password included in the information input through the input means and the password input through the password input means do not match, , The password included in the information entered through the input means matches the password entered through the password input means And transmitting means for transmitting caller identification information included in the information input through the input means to the second communication terminal device at the time of outgoing call, and the connection device transmits the first communication terminal device at the time of outgoing call. A transmission means for receiving the received caller identification information, and a transmission for transmitting the caller identification information received by the reception means to the second communication terminal apparatus designated by the first communication terminal apparatus together with a signal for informing the incoming call. Means.

  As described above, according to the present invention, when the first communication terminal apparatus authenticates the caller with the encrypted information and the password and confirms that the caller is a valid user, the first communication terminal apparatus The terminal identification information assigned to the caller and the identification information of the caller are transmitted at the time of outgoing call, and the connection device sends the caller identification information and the terminal identification information notified from the first communication terminal device to the second caller side. Is sent to the communication terminal device to notify the incoming call.

  Therefore, according to the present invention, since authentication on the network side is not required, an authentication request from the communication terminal device on the transmission side to the network is unnecessary, and even if the authentication fails, the communication terminal device on the transmission side Even without communication with the user, the user can immediately recognize the failure of authentication, the network load is small, and if the authentication is successful, the caller side terminal identification information and Caller identification information can be notified when an incoming call is received. For this reason, it is possible to notify the receiving terminal of information specifying the caller without imposing a heavy load on the network, and it is also possible to notify the identification information of the terminal that made the call together. High nature.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a communication system according to an embodiment of the present invention. Here, a mobile communication system will be described as an example.

A base station 220b wirelessly connected to 210b, an exchange 230b that accommodates the base station 220b, a billing server 250 that manages a usage fee of the system, and a network 240 that houses the exchanges 230a and 230b and the billing server 250 It has.

FIG. 2 shows the configuration of the mobile phone 210a on the calling side. It is assumed that the configuration of mobile phone 210b on the incoming side is the same as that of mobile phone 210a.
The mobile phone 210a includes a camera unit 101, an authentication processing unit 102, a storage unit 103, a display unit 104, a wireless unit 105, an input unit 106, a call unit 107, and a control unit 108.

  The camera unit 101 is an imaging unit that can image a person, a landscape, and the like, and can image the two-dimensional barcode 109. The camera unit 101 has a function of converting a captured image into image data of a predetermined format.

  The two-dimensional barcode 109 is uniquely assigned to each service subscriber, and subscriber identification information for identifying the service subscriber and password information associated with the subscriber identification information are encrypted. It has been done.

  This two-dimensional barcode 109 is distributed in advance to the service subscriber. Here, for example, a credit card number may be considered as the subscriber identification information, and it may be printed on the back side of the credit card.

  The authentication processing unit 102 receives the image data obtained by the camera unit 101 and decodes the image data when the image data is a two-dimensional bar code 109 to obtain a subscriber number and a password. A function for verifying whether the information input through the input unit 106 matches the password.

  The storage unit 103 includes a telephone number (caller number) assigned to the mobile phone 210a, telephone directory data in which the telephone number is associated with a name, a subscriber number decrypted by the authentication processing unit 102, a control unit described later 108 control programs and control data are stored.

The wireless unit 105 wirelessly transmits input voice data to the base station 220a and receives voice data from the base station 220a.
The input unit 106 includes a plurality of key switches and receives a request from a user.

  The calling unit 107 includes a microphone and a speaker. The calling unit 107 converts a transmitted voice input through the microphone into the voice data, decodes the voice data received from the other party through the base station 220a, and outputs a loud sound from the speaker. To do.

  The control unit 108 performs overall control of each unit of the mobile phone 210a. When the power is turned on, the control unit 108 reads the control program and control data from the storage unit 103, controls outgoing calls, and receives outgoing calls. Control incoming call control according to data, call control, display control of display unit 104, input control through input unit 106, recording / reading control of information to storage unit 103, imaging control through camera unit 101, and authentication processing unit 102 Various controls such as control related to caller-designated transmission are performed.

Next, the operation of the mobile communication system configured as described above will be described.
FIG. 3 is a flowchart for explaining the operation of the mobile communication system. Hereinafter, a description will be given with reference to this figure.

  First, in the cellular phone 210a, a user requests a caller-designated call by operating a specific function key through the input unit 106 (step 301). Receiving this, the control unit 108 activates the camera unit 101 and the authentication processing unit 102, and proceeds to step 302.

  In step 302, the control unit 108 displays a message such as “Please photograph a two-dimensional barcode” on the display unit 104, and prompts the user to photograph the two-dimensional barcode 109. When the user operates the input unit 106 to photograph the two-dimensional barcode 109 with the camera unit 101, the camera unit 101 outputs image data obtained by the photographing to the authentication processing unit 102, and the process proceeds to step 303.

  In step 303, the control unit 108 instructs the authentication processing unit 102 to decode the image data. On the other hand, the authentication processing unit 102 decodes the two-dimensional barcode 109 included in the image data to obtain password information. The password information obtained in this way is notified to the control unit 108.

  Then, the control unit 108 displays on the display unit 104 "Please enter the password", prompts the user to input the password, and accepts the input of the password from the user through the input unit 106. Transition to 304.

  In step 304, the control unit 108 determines whether or not the password information obtained by the authentication processing unit 102 matches the password input from the user through the input unit 106. If the passwords match, the process moves to step 306. On the other hand, if the passwords do not match, the process moves to step 305.

  In step 305, the control unit 108 displays a message such as “passwords do not match” on the display unit 104 and ends the processing. Instead of ending the process with one input failure in this way, for example, up to three failures may be allowed, and the process may be ended when more failures occur.

  In step 306, the control unit 108 instructs the authentication processing unit 102 to decode the image data. On the other hand, the authentication processing unit 102 decodes the two-dimensional barcode 109 included in the image data, and obtains subscriber identification information for identifying the service subscriber. The subscriber identification information obtained in this way is notified to the control unit 108, recorded in the storage unit 103 by the control unit 108, and the process proceeds to step 307.

  In step 307, the control unit 108 displays a message such as “Please enter the other party's phone number” on the display unit 104, and prompts the user to input the destination phone number. Then, the control unit 108 accepts an input of the destination telephone number from the user through the input unit 106, and proceeds to step 308.

  In step 308, the control unit 108 controls the wireless unit 105, the special number data, the destination telephone number, the subscriber identification information recorded in the storage unit 103 in step 306, and the telephone assigned to the mobile phone 210 a. The call data including the number (caller number) is transmitted to make a call, the called party is called, and a response is waited.

  On the other hand, the exchange 230a that has received the call data through the base station 220a transmits the call data to the billing server 250 as step 309, and receives the destination telephone included in the call data. Based on the number and location registration information managed on the network 240, the base station 220b to which the mobile phone 210b that is the destination is associated is specified, and the incoming call is notified to the mobile phone 210b through the exchange 230b and the base station 220b. To do. In this incoming call notification, the call data is transmitted to the mobile phone 210b.

  On the other hand, the billing server 250 determines that the call is a caller-designated call since the special call data is included in the received call data as step 309, and the charge object is included in the call data. As a subscriber corresponding to the subscriber identification information, not the subscriber of the caller number, preparations for charging are made.

  On the other hand, when the mobile phone 210b receives the incoming signal through the base station 220b, in step 310, the control unit 108 extracts the outgoing data from the incoming signal, and since the special number data is included in this data, the incoming call is not received. It is determined that the call is a caller-designated call, and a caller number and subscriber identification information included in the call data are extracted.

  Then, the control unit 108 of the mobile phone 210b outputs a ringing tone, and displays the extracted caller number and subscriber identification information so that the display unit 104 can be distinguished, for example, as shown in FIG. The user is notified of the incoming call. FIG. 4 shows an example in which a mobile phone number used by a subscriber is used as subscriber identification information.

  Here, when the caller number and the name are associated with each other in advance as phone book data in the storage unit 103 and the subscriber identification information and the name are associated with each other and stored, the corresponding names are respectively stored. The control unit 108 performs control so as to display on the display unit 104.

  Eventually, when the user of the mobile phone 210b indicates an intention to respond to an incoming call by operating the input unit 106, the control unit 108 controls the radio unit 105 to transmit a response signal to the base station 220b as step 311. .

  On the other hand, the exchanges 230b and 230a cooperate to control the base stations 220b and 220a, respectively, to establish a communication link between the mobile phone 210a and the mobile phone 210b. Is ready for a call (step 312).

  In step 313, the billing server 250 starts billing for the subscriber corresponding to the subscriber identification information. Thereafter, the billing server 250 performs this billing until the communication link is disconnected. In addition, when the call ends, the mobile phone 210a deletes the subscriber identification information recorded in the storage unit 103.

  As described above, in the communication system configured as described above, when a two-dimensional barcode 109 including subscriber identification information and a password is input to the mobile phone 210a through the camera unit 101 in advance, the password input by the user matches. The subscriber identification information is transmitted, and the subscriber identification information is notified to the receiving side.

  Therefore, according to the communication system having the above-described configuration, even if the user does not store the subscriber identification information, the user makes a call using the subscriber identification information assigned to the user and notifies who the caller is. It is so convenient.

  Further, in the communication system configured as described above, a call made using the subscriber identification information from the mobile phone 210a is not charged to the owner of the mobile phone 210a that made the call, but a subscription corresponding to the subscriber identification information. Since the user is charged, it is easy to lend and borrow the mobile phone 210a.

  Furthermore, in the communication system configured as described above, when the mobile phone 210a makes a call using the subscriber identification information, the mobile phone 210b on the receiving side is notified of the subscriber identification information and the telephone number of the mobile phone 210a that made the call, Since the mobile phone 210b on the receiving side displays these pieces of information when receiving a call, the user of the mobile phone 210a can recognize who is making a call from which phone.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiment is also conceivable. Furthermore, you may combine suitably the component described in different embodiment.

  For example, in the above-described embodiment, a mobile phone system has been described as an example of the communication system. However, the present invention can be applied to a communication system using a wired line such as a fixed telephone, and VoIP ( The present invention can also be applied to a communication system using a Voice over Internet Protocol) network.

  In the above embodiment, the two-dimensional barcode 109 has been described as an example. However, the encrypted two-dimensional information that cannot be easily recognized by humans is limited to the two-dimensional barcode 109. is not.

  Further, in the above embodiment, the subscriber identification information and the password information are included in the two-dimensional barcode 109, but the user's biometric information may be stored instead of the password.

  As the biometric information, a user's retina pattern or iris pattern can be considered. In place of password input, the camera unit 101 captures the user's retina pattern or iris pattern, and controls whether the captured pattern matches the biometric information stored in the two-dimensional barcode 109. The unit 108 makes a determination and makes a call using the subscriber identification information if they match.

  Even with such control, the same effect is obtained. Biometric information may be a fingerprint. In this case, fingerprint imaging by the camera unit 101 can be considered, but a contact-type input unit for reading a fingerprint may be provided.

  In the above embodiment, the subscriber identification information is decrypted from the two-dimensional barcode 109 when the password is correctly input. Instead, for example, the subscriber information is encrypted with the password. The encrypted data may be converted into a two-dimensional bar code, and the subscriber information may be restored by decrypting the code using the input password.

  Further, instead of the password, encryption may be performed using the biometric information as described above, and the subscriber information may be restored by decrypting the encryption using the input biometric information.

  Furthermore, in the above embodiment, the voice communication has been described as an example, but the present invention can also be applied to data communication. In this case, when a plurality of users share the communication terminal or when borrowed from another person, the user can be surely charged, and the communication terminal can be easily shared or rented.

  In this case, a wireless LAN terminal device can be considered as the communication terminal. In the case of a wireless LAN terminal, the wireless LAN terminal serves as the wireless unit 105, uses a digital camera provided in a mounted personal computer or the like as the camera unit 101, and the input unit 106 uses a keyboard or mouse of the personal computer. The control unit 108 can be realized by the CPU and memory of the personal computer. The storage unit 103 for storing the control program and control data can use a hard disk of a personal computer.

  Further, in the above embodiment, the subscriber information is notified to the mobile phone 210b on the receiving side. Instead, for example, the subscriber information and the telephone number used by the subscriber on the network 240 are used. May be provided, and the server device may notify the mobile phone 210b on the receiving side of the telephone number corresponding to the subscriber information for the caller-designated transmission.

In the above embodiment, the two-dimensional barcode 109 is described as an example of information including subscriber identification information and a password (biometric information). However, it cannot be easily recognized by humans and is captured by the camera unit 101. If it is possible information, it is not limited to this.
In addition, it goes without saying that the present invention can be similarly implemented even if various modifications are made without departing from the gist of the present invention.
