Description

  The present invention relates to a communication terminal apparatus capable of bidirectional communication, and more particularly to a communication terminal apparatus having a display device that displays information related to a caller's telephone number and the like when an incoming call is received.

  When an incoming call is received by telephone, the caller's telephone number is generally displayed. In this case, if the telephone number is registered in the telephone directory mounted on the telephone, the user can easily identify the caller by displaying the name registered in the telephone directory. When there is an incoming call from a telephone number not registered in the telephone directory, generally only the telephone number is displayed. Regardless of the other party who often talks over the phone, it is difficult to identify the caller when receiving calls from other phone numbers. If it is desired to easily identify the caller, it is necessary to register as many telephone numbers as possible in the telephone directory.

  However, it is difficult to register all communication partners in the phone book. In particular, it is common not to register in the telephone directory when the communication partner is not a frequent partner. Since there are restrictions on the telephone numbers that can be stored in the telephone directory, it is considered that telephone numbers that can only be assumed rarely are not registered in the telephone directory.

  However, even a telephone number that is not registered in the telephone directory in this way cannot be said to be an important incoming call for the receiving side. If you do not answer such a phone call, there can be a significant penalty. Therefore, there is a demand for a communication terminal that can easily identify a caller from the telephone number when an incoming call is received.

Regarding the technology for identifying a caller, in Patent Document 1 described later, when there is an incoming call from a telephone number that is not registered in the telephone directory, the area that is prepared in advance and lists the area corresponding to the area code An information display device is disclosed that uses a ROM (read only memory) storing information data and an incoming call history to identify and display a caller from an incoming call number.
JP 2000-236381 (FIG. 4 and paragraph 0023)

  However, the communication terminal device of Patent Document 1 merely associates the area information data such as the area code information prepared in advance with the reception history, so that the information corresponding to the incoming telephone number can be obtained. If it is not stored in the regional information data, no information about the caller can be obtained. On the other hand, even if there is an incoming call from a partner who is not interested in you, if there is information in the local information data, that information will be displayed. There is a problem that it cannot be judged.

  In this connection, for example, there are the following problems. To make a hotel reservation, consider a case where a telephone number is looked up by telephone number guidance, the hotel is called, and the reservation date / time, own name, and telephone number are communicated. There is a case where the hotel confirms a reservation after a predetermined time, or a telephone notifies that the reservation is canceled due to some trouble. Generally, hotel reservations are not made on an ongoing basis, and the hotel phone number is rarely registered in the phone book. Therefore, in the conventional technique using only the telephone directory, only the hotel telephone number is displayed on the screen when an incoming call is received. After making a hotel reservation, if you make a call to another person or receive an incoming call from another person, or if a long time has passed, no one will call you even if only the phone number is displayed. I don't know what to do and I'm wondering if I should answer the call.

  On the other hand, in the technique described in Patent Document 1, the name of the hotel may be displayed in such a case. However, it may not be displayed. If it is not displayed, you will not immediately know where the call came from. Also, if it is displayed, it is necessary to look at the name of the hotel and then remember that you made a reservation call to the hotel. If you have forgotten that you have made such a reservation, the name of the hotel may appear, but there will be no passage, and you may be wondering whether to answer the call.

  In this way, it is desirable to provide a telephone that can make a decision that can immediately answer an incoming call for a telephone that is important to you even if it is not registered in the telephone directory. . Such a problem is not limited to a telephone, and is generally a problem common to communication terminal apparatuses for performing bidirectional communication with a partner.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a communication terminal device that can easily determine whether or not it is possible to immediately respond to an incoming call when there is an incoming call from another station.

  Another object of the present invention is to provide a communication terminal apparatus that can immediately determine when there is an incoming call from a destination that has sent from itself.

  In response to a communication request from a communication terminal, the communication terminal device according to the first aspect of the present invention responds to a communication request specifying an incoming call display means for displaying the address of the communication terminal and the address of the communication terminal. A transmission means for transmitting communication to the address, and a transmission history recording means for recording a transmission history including the address of the destination in response to the transmission by the transmission means. The communication terminal device includes an incoming call display unit that, upon receiving a communication request from another communication terminal, refers to the outgoing call history recording unit and is a communication terminal whose outgoing call history is recorded in the outgoing call history recording unit. Address display means for displaying the address of the communication terminal is included.

  When there is a call from the communication terminal, the call history recording means records a call history including the address of the communication terminal of the call destination. When there is an incoming call from another communication terminal, the address display means refers to the call history recording means, so that it is possible to distinguish between when there is a call history to the communication terminal and when there is no call history. Display the address. It can be easily determined whether the communication terminal has transmitted from here in the past or the communication terminal that has not transmitted from the address display means. Based on the display, it can be determined whether or not an incoming call should be answered immediately. As a result, it is possible to provide a communication terminal device that can immediately determine when there is an incoming call from the communication terminal of the other party that has transmitted from itself.

  Preferably, the communication terminal apparatus further includes terminal address storage means for storing the address of the communication terminal. When the address display means receives a communication request from another communication terminal, the address display means refers to the call history recording means and the terminal address storage means, or the communication terminal whose address is recorded in the terminal address storage means or the terminal address storage means The address is not recorded in the communication terminal and the transmission history is recorded in the transmission history recording means, or the address is not recorded in the terminal address storage means, and the transmission history is recorded in the transmission history recording means. Means for displaying the address of the communication terminal in a different manner from each other so that a communication terminal that is not connected can be identified.

  The terminal address storage means stores the address of the communication terminal. Since this address is stored in this terminal address storage means, it is a meaningful address for the user of this communication terminal. According to this communication terminal device, an incoming call is from a communication terminal whose address is recorded in the terminal address storage means, or a communication terminal in which no address is recorded in the terminal address storage means and there is a call history from here Whether the address is from a communication terminal in which no address is recorded in the terminal address storage means and there is no outgoing call history can be determined by the display mode. If there is an incoming call from a communication terminal whose address is recorded in the terminal address storage means, or an incoming call from a communication terminal that is not recorded in the terminal address storage means but has a call history from here, the user of this communication terminal apparatus Therefore, it can be determined that the incoming call is from a communication terminal of a related user. On the other hand, in other cases, there is a high possibility that the incoming call is from a communication terminal unrelated to the user. As a result, it is possible to provide a communication terminal device that can immediately determine when there is an incoming call from a communication terminal of a partner that has some relationship with itself.

  Preferably, the transmission history recorded by the transmission history recording means includes information for specifying the address of the transmission destination and the date and time when the transmission was made, and the address display means has the transmission history recorded in the transmission history recording means. Even if it is a communication terminal, if a call is made more than a predetermined time before the date and time when an incoming call is received, it is handled as a communication terminal in which no call history is recorded.

  Even if a communication terminal has a transmission history from here in the past, if the date and time are too old, it is considered that the communication terminal is not so relevant to the user. Therefore, by treating such a communication terminal as a communication terminal in which no outgoing call history is recorded, it can be easily determined that the call is an incoming call from a partner that does not need to go out.

  Preferably, the transmission history recorded by the transmission history recording means includes a destination address and the date and time when the transmission was made, and the address display means is for a communication terminal whose transmission history is recorded in the transmission history recording means. The address of the communication terminal and the date and time when the call was made to the address are displayed as a pair.

  The transmission history recording means records the address of the transmission destination as a transmission history together with the date and time when the transmission was made. When there is an incoming call from a communication terminal having a call history from here, the address display means refers to the call history of the call history recording means and displays the date and time of the call together with the address. The user displays the transmission date and time together with the address of the communication terminal, so that the address of the communication terminal is not recorded in the address recording means, and the transmission history from the communication terminal apparatus is stored in the transmission history means. You can immediately know what happened and when it was sent. As a result, it can be easily determined whether or not an incoming call should be answered immediately.

  When the computer program according to the second aspect of the present invention is executed by a computer having means for communicating with another communication terminal, the computer program responds to a communication request from the communication terminal. Incoming call display means for displaying the address of the terminal, in response to a communication request specifying the address of the communication terminal, sending means for sending communication to the address, and sending by the sending means In response, a computer program that functions as a transmission history recording means for recording a transmission history including a destination address, and the incoming call display means receives a communication request from another communication terminal and records the transmission history The communication terminal in such a manner that it can be identified whether or not the communication terminal has a call history recorded in the call history recording means. To display the address.

  When this computer program is executed by a computer having means for communicating with another communication device, the computer operates in the same manner as the communication terminal device according to the first aspect. As a result, the same effect as the communication terminal device according to the first aspect can be obtained.

  As described above, according to the present invention, it is possible to easily determine whether a communication terminal that has made a call from here or a communication terminal that has not made a call by looking at the display of the address by the address display means. Therefore, it is possible to provide a communication terminal device that can immediately determine when there is an incoming call from the communication terminal of the other party that has transmitted from itself. In addition, at the time of an incoming call, a communication terminal whose address is stored in the terminal address storage means and a communication terminal having a call history from here are displayed separately from other communication terminals. As a result, when there is an incoming call from a communication terminal of a partner having some relationship with him, it can be immediately determined.

  Even a communication terminal that has been transmitted from here in the past is considered not to be a user's communication terminal that is so relevant to the user if the date is too old. By treating such a communication terminal as a communication terminal in which no outgoing call history is recorded, it is possible to easily determine that the incoming call is from a partner that does not need to respond to the user.

  Also, when there is an incoming call from a communication terminal that has a call history from here, if the date and time of the call is displayed along with the address, the user must be the terminal that the communication terminal has sent from here , And when it was sent out. As a result, it can be easily determined whether or not to respond immediately to an incoming call.

  Embodiments of the present invention will be described below. In the following description and drawings, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[Operation]
The cellular phone 40 according to this embodiment operates as follows. Hereinafter, description will be made mainly with reference to the flowchart of FIG. When the mobile phone 40 is turned on, a standby screen is displayed on the LCD 58 in step 170. Subsequently, in step 172, it is determined whether or not there is a transmission instruction. When the user gives an instruction to make a call using the keypad 59 shown in FIG. 2, this is detected in step 172, and the process proceeds to step 174. If there is no transmission instruction, the process proceeds to step 180. Hereinafter, a case where there is an instruction to make a call will be described first.

  In step 174, the communication control unit 120 shown in FIG. Make a call. Subsequently, at step 176, if the other party responds to this call, a call is performed, and if there is no response, a process of disconnecting according to a user instruction is performed. In step 178, the outgoing call history is updated. Here, the telephone number of the other party input by the user and the time measured by the clock unit 100 when a call is issued are paired and recorded in the call history 150 as one entry. Thereafter, the process returns to step 170 to display a standby screen.

  If it is determined in step 172 that there is no outgoing instruction, it is determined in step 180 whether there is an incoming call. If there is no incoming call, the process returns to step 170, but if there is an incoming call, the process advances to step 182. In step 182, it is determined whether the incoming call number is registered in the telephone directory 152 shown in FIG. The following description will be divided into a case where it is registered, a case where it is not registered but there is a call history within the past day, and a case other than that.

  If it is determined in step 182 that the incoming call number is registered in the telephone directory, it is determined in step 194 whether or not the corresponding entry in the telephone directory has a name corresponding to the telephone number. If there is a registration, the telephone book registration name is displayed as an incoming call display in step 196 (FIG. 1A). Thereafter, the process proceeds to step 190, where a telephone call is made or if the user does not answer, the process returns to step 170 after waiting for a disconnection instruction from the partner.

  If it is determined in step 194 that the name corresponding to the incoming call number is not registered in the telephone directory 152, the process proceeds to step 188. In step 188, the symbol “*” and the incoming call number are displayed as an incoming call display (FIG. 1B). If there is a transmission record, the transmission date and time is displayed. Thereafter, a call process or a disconnection process is performed in step 190, and the process returns to step 170.

  On the other hand, if it is determined in step 182 that the incoming number is not registered in the telephone directory, the process proceeds to step 184 to determine whether or not the telephone number exists in the outgoing call history 150. If it is not in the outgoing call history, the process proceeds to step 192, where only the incoming call number is displayed as an incoming call display, and then a call or disconnection process is performed in step 190 and the process returns to step 170.

  If it is determined in step 184 that the call is in the outgoing call history, then in step 186, the current time is compared with the outgoing time corresponding to the incoming call number in the outgoing call history, and whether or not one day has passed since the call was made. Judge about. If more than one day has passed, the process proceeds to step 192, and the subsequent processing is as described above. If one day or more has not elapsed since the transmission, control proceeds to step 188. In step 188, as shown in FIG. 1B, the symbol “*”, the incoming call number, and the outgoing call date and time are displayed as the incoming call display. Thereafter, the telephone call process or the disconnection process is performed in step 190, and then the process returns to step 170.

  According to this embodiment, when there is an incoming call from the other party registered in the telephone directory, the display 42 shown in FIG. From the display 42, the user can immediately determine who the incoming call is from. If the incoming call number is not registered in the telephone book and is not a caller within the past day, a display 46 shown in FIG. 1C is output on the LCD 58. Therefore, in this case, the user can immediately recognize that the other party of the incoming call number is not registered in the telephone directory and is not the party who has sent from here within the past one day. The above is the same as in the case of the prior art.

  In the present embodiment, in addition to these, even if the incoming number is not registered in the telephone directory, if the incoming number is the other party's incoming number within the past day, ), Not only the telephone number but also the symbol “*” and the transmission date and time are displayed. In the present embodiment, a phone number is registered in the phone book, but a name as shown in FIG. 1B is displayed even for a partner whose name is blank. Therefore, when the user sees this display, the incoming call is not in the phone book, but it is an incoming call from a partner who has made a call from here within a certain period, or it is registered in the phone book, but the name is registered. It is possible to immediately determine that the incoming call is from a partner who is not. Therefore, from this display, it can be determined that the incoming call can be immediately answered.

  As described above, according to the present embodiment, an incoming call from the other party registered in the telephone directory, or an incoming call from the other party that is not in the telephone directory but is sent from here within a certain period, or registered in the telephone directory. On the LCD 58, whether the incoming call is from the other party whose name is not registered or from the other party who has not been registered in the phone book and has not been sent from here within a certain period of time. Can be determined immediately by looking at the output. If there is an incoming call from a person who is not in the phone book, if you know that it is an incoming call from the other party within a certain period in the past, or an incoming call from a person registered in the phone book, You can immediately answer the phone and get important information. There is an effect that it is possible to easily determine whether or not it is possible to respond to the incoming call as compared with the case where only the telephone number is displayed for the other party not in the telephone directory.

  In the above-described embodiment, the date and time of transmission to the incoming call number are displayed together with the symbol “*”, but the present invention is not limited to such embodiment, and the transmission date and time may not be displayed. .

[Second Embodiment]
In the first embodiment described above, although it is not registered in the phone book, the incoming call from the other party that has been sent from here within a certain period in the past and the phone number are registered in the phone book, but the name Is an incoming call from a partner who is not registered, as shown in FIG. 1B, the incoming call number is displayed with the symbol “*” and the call date and time. Therefore, for the user, there is an effect that it is possible to immediately determine whether or not the call is a call from an unrelated party. However, in the display of the first embodiment, it is an incoming call from a party who is registered in the phone book but not registered in the name, or is a party who is not registered in the phone book, and from here within a certain period. It cannot be distinguished whether the incoming call is from a partner who has made a call. It may be desirable for some users to be able to make such a distinction. The mobile phone according to the second embodiment described below can further distinguish between these two cases.

  A display 210 shown in FIG. 5 shows a display output on the LCD 58 shown in FIG. 1 when the incoming call is from a party whose telephone number is registered in the telephone directory but whose name is not registered. In the present embodiment, although not in the telephone directory, if there is an incoming call from the other party who has made a call within a certain period, a display 44 shown in FIG. 1B is displayed. Therefore, the two cases can be clearly distinguished by the display on the LCD 58.

  FIG. 6 shows a flowchart of a program executed by the mobile phone according to the second embodiment. The flowchart shown in FIG. 6 is almost the same as the flowchart shown in FIG. 4, except that it is determined in step 194 in FIG. 4 that the incoming call number is registered in the telephone directory but the name is not registered. , Except that the process proceeds to step 220 instead of proceeding to step 188. In step 220, a display (display 210 in FIG. 5) indicating that the incoming number is in the telephone directory but the name is not registered is displayed on the LCD 58, and the process proceeds to step 190. The subsequent processing is the same as in FIG.

  In the second embodiment, as described above, when the display shown in FIG. 1 (B) is performed, it is not registered in the telephone directory, but is transmitted from here within a certain period. When the display 210 shown in FIG. 5 is displayed, the incoming call number is registered in the phone book, but the call is not received from the other party whose name is not registered. You can see that it is an incoming call. Therefore, in this case, more detailed information about whether or not to respond to the incoming call can be obtained, and it can be determined whether or not to respond to the incoming call more easily than in the first embodiment.

  In the above embodiment, the symbol “*” is displayed when an incoming call is received from a partner whose call has been made within a day. However, in this case, the symbol is not displayed.
