Description

  The present invention relates to a mobile communication terminal, and more particularly to a mobile communication terminal having a relay function.

  Due to the revision of the Road Traffic Law, the operation of mobile phones while driving a car is prohibited. When you make a call while driving, you are required to use a hands-free kit, but even if you use a hands-free kit, you can concentrate on operations that answer incoming calls and conversations with other parties. Concentration of the person is reduced, and there is a risk of danger. There is also a problem that a mobile phone can be used even when the hands-free kit is not used intentionally.

It is dangerous to operate the mobile communication terminal during driving because concentration on driving decreases. In addition, it is a well-known fact that when using a hands-free kit, the concentration on driving is reduced by concentrating on conversation. As a measure for preventing such danger, a technique has been shown in which incoming calls are restricted when the driver has no room by detecting the vehicle condition and moving speed (see, for example, Patent Document 1).
In addition, when a hands-free call is made when a plurality of mobile communication terminals are installed in a vehicle and a hands-free call is possible, a Bluetooth communication unit can communicate with other mobile communication terminals. There is known a mobile communication terminal in which the mobile communication terminal is set in a drive mode by performing wireless communication via the communication (for example, see Patent Document 2).

  Furthermore, when a mobile communication terminal communicates only between users who are permitted to transfer emergency information and any one of a plurality of mobile communication terminals having short-range communication means receives the emergency information, A mobile communication terminal is also known that, when searching for and detecting another terminal capable of distance communication, detects emergency information (see, for example, Patent Document 3).

JP 2001-144850 A JP 2003-174676 A JP 2003-244068 A

  However, the conventional mobile communication terminal described in Patent Document 1 requires a connection between a mobile communication terminal, which is a mobile phone, and a hands-free device or an in-vehicle device. If it is not connected to the PC, it will not function, and the use is limited, so that there is a problem that the usability deteriorates.

  In addition, the conventional mobile communication terminal described in Patent Document 2 is configured to switch the incoming call from the base station to the first mobile communication terminal to the incoming call from the base station to the second mobile communication terminal. The first mobile communication terminal maintains a line with the base station, and only communication data cannot be transferred between the first base station and the second base station. Furthermore, the conventional portable communication terminal described in Patent Document 3 performs transfer for the purpose of expanding information to an unspecified number of people, and responds to an incoming call to a specific portable communication terminal that is in operation. Is not something to do.

  The present invention has been made in view of the above points, and it is possible to improve safety without reducing the concentration of driving against incoming calls during driving, and inconvenience that a mobile communication device cannot be used during driving. An object is to provide a mobile communication terminal having a relay function that can be eliminated.

  Another object of the present invention is to provide a portable communication terminal capable of preventing danger due to a call with a partner terminal during driving without connecting to another device such as a hands-free device. .

When the other terminal satisfies the connection condition and the connection condition determining means for determining whether or not the second terminal satisfies the connection condition, the second communication means receives at least the signal received from the partner terminal by the first communication means. Middle joint to transfer as it is Characterized in that it has and.

  In this invention, when the incoming signal is received by the first communication means when the owner is in the drive mode because of driving, the incoming signal is received by other peripheral terminals, and Since the incoming signal is directly transferred to the other terminal satisfying the predetermined connection condition by the second communication means of the short-range communication method, the incoming other terminal can respond to the incoming call. Here, the other terminal is a mobile communication terminal, and the incoming signal is an incoming call signal for electronic mail or telephone communication.

  In order to achieve the above object, the present invention obtains the above-mentioned connection condition determining means from the searched other terminal by using the second communication means, and the obtained telephone number is The means for detecting whether there is a matching telephone number among the telephone numbers stored in the address book data storage means for storing the telephone number of a desired connectable terminal in advance. .

  In the present invention, the incoming signal is transmitted only to other terminals having a telephone number among telephone numbers stored in the address book data storage means among other peripheral terminals. It is possible to realize a portable communication terminal having a relay function that avoids incoming call transfer.

  In order to achieve the above object, according to the present invention, when the incoming signal is an incoming call signal for telephone communication, the relay means sends a response signal to the incoming call signal from another terminal as the second communication means. Is transmitted to the counterpart terminal by the first communication means after being received by the first communication means to establish the line connection with the counterpart terminal via the first communication means and maintain the line connection in the first communication. The first voice data from the partner terminal received by the means is transferred to another terminal by the second communication means, and the second voice data from the other terminal received by the second communication means is transferred to the first communication. It is a means to transmit to a partner terminal by a means, It is characterized by the above-mentioned.

  In this invention, even when telephone communication is performed between the partner terminal and another terminal, the line connection state between the partner terminal and the original mobile communication terminal of the present invention is maintained, so that the partner Communication is immediately possible without re-establishing line connection between the terminal and another terminal.

  In order to achieve the above object, the present invention does not transfer the relay means to the other terminal when the incoming signal received from the counterpart terminal by the first communication means is an electronic mail. When the incoming signal is an incoming call signal for telephone communication, it is transferred to the other terminal by the second communication means. In the case of an e-mail, even if it is not in operation, it can be viewed later after the operation is completed, so there is no problem even if it is not transferred to another terminal.

  In order to achieve the above object, according to the present invention, when the incoming signal is an incoming call signal for telephone communication, a response signal to the incoming call signal from another terminal is input by the relay means within a predetermined time. If not, it further comprises message transmission means for automatically generating a message indicating that the incoming call cannot be answered and transmitting it to the partner terminal via the first communication means.

  In the present invention, when there is no response within a certain time, a message indicating that the incoming call cannot be answered is automatically transmitted to the receiving terminal, so that the receiving terminal transmits the incoming call signal many times. Waste can be eliminated.

  Furthermore, in order to achieve the above-mentioned object, the present invention provides another terminal in the vicinity capable of short-range communication searched by the search means, and another person riding in the same vehicle or other two or more persons riding together. It is a mobile communication terminal possessed by each person.

The short-distance communication line connection in Bluetooth of the mobile phones 4 and 5 of the passengers C and D is maintained, and the mobile phones 4 and 5 of the passengers C and D perform an incoming call operation (step S108). The above connection condition is that the telephone numbers of the passengers C and D are registered in the address book data storage unit (corresponding to 104 in FIG. 2) of the driver's mobile phone 3.

  If there is no mobile phone that can be connected around the driver B (step S104), or even if there is a mobile phone that can be connected around the driver B, the connection condition is not met (step S107), the mobile phone 3 The control unit automatically transmits a message to the caller indicating that the callee cannot answer the call because the callee is driving (step S105).

  The mobile phones 4 and 5 possessed by the passengers C and D shown in FIG. 1 can be connected to the mobile phone 3 in a short-distance communication line, and if the mobile phones 4 and 5 match the connection conditions, When one of the passengers C and D presses the call button of the mobile phone 4 or 5 that he / she owns and responds to the incoming call during the incoming operation of the phone 4 or 5 (step S109), the mobile phone of another passenger After stopping the incoming call operation, the Bluetooth connection of the other passenger's mobile phone is disconnected (step S110). In the example of FIG. 4 described above, the passenger C presses the call button and responds to the incoming call, so the Bluetooth connection (short-distance communication line connection) between the mobile phone 5 of the other passenger D and the mobile phone 3 of the driver B Is disconnected.

  Subsequently, as described in conjunction with FIG. 5, the mobile phone 1 of the caller A and the mobile phone 3 of the driver B are connected to a mobile communication line in the signal format of the mobile phone (step S111). Since the mobile phone 3 and the mobile phone 4 of the passenger C who responds to the incoming call are connected via Bluetooth, the caller A and the passenger C can talk over the mobile phone 3 of the driver B (step S112). ).

  When the call is ended and the passenger C or the caller A presses the call disconnect button of the mobile phone 4 or 1 held by the passenger C or the caller A (step S113), first, the caller A's mobile phone 1 and the driver B's mobile phone The mobile communication line with the telephone 3 is disconnected (step S114), and then the Bluetooth connection between the mobile phone 3 of the driver B and the mobile telephone 4 of the passenger C is disconnected (step S115).

  If the passenger does not press the call button during the incoming call operation (No in step S109), the incoming-side mobile phone 3 automatically displays a message indicating that it cannot respond to the incoming call because it is driving after a certain period of time. To caller A (step S105).

  As described above, according to the present embodiment, it is possible for the passenger to respond to the incoming call to the mobile phone of the driver using the mobile phone that he / she owns. Therefore, it is possible to improve the safety without reducing the concentration of driving for incoming calls without concentrating on the conversation and reducing the concentration of driving. In this embodiment, it is not necessary to connect an external device such as a hands-free kit, and even if you do not have a hands-free kit, you can communicate with the other party. Can eliminate the inconvenience that can not be used, and it does not restrict incoming calls and use, so there is no inconvenience.

  Next, the details of the connection operation in Bluetooth will be described with reference to the flowchart of FIG. When the mobile phone 3 possessed by the driver B in FIG. 1 receives an incoming call while the drive mode is set (step S201), the mobile phone 3 of the driver B and the mobile phones 4 of the passengers C and D, 5 are connected via Bluetooth (step S202). The connection is a connection for determining whether call transfer is possible. When there are a plurality of passengers such as C and D as shown in FIG. 1, the plurality of passengers are connected to the respective mobile phones (however, each of the plurality of passengers' mobile phones has a Bluetooth communication function). If).

  Requesting the passenger's mobile phone number information from the driver's mobile phone to the passenger's mobile phone via the Bluetooth line (step S203), and in response to this request, the passenger's mobile phone receives the driver's mobile phone. The user's own telephone number information is transmitted (step S204). The control unit of the driver's mobile phone determines whether or not the passenger's phone number received through the Bluetooth line is registered in the address book data storage unit of the driver's mobile phone (step S205).

  If the passenger's telephone number is not registered in the address book data storage unit, the passenger's Bluetooth line connection is disconnected and the incoming call transfer is not performed (step S206). On the other hand, if the passenger's phone number is registered in the rear Ceres book data storage unit, the driver's mobile phone and the passenger's mobile phone will be connected to the Bluetooth line, and the driver's mobile phone will receive an incoming call. Transfer to the passenger's mobile phone (step S207).

  After that, by pressing the call button of the mobile phone held by the passenger, a call start signal is transmitted from the passenger's mobile phone to the driver's mobile phone via the Bluetooth line, and further from the driver's mobile phone. A start signal is wirelessly transmitted to the base station, and a line is established from the base station to the mobile phone of the caller via the mobile wireless network. Thereafter, voice data between the passenger's mobile phone and the driver's mobile phone is transmitted / received via a Bluetooth line, and between the driver's mobile phone and the base station via a line according to the signal format of each mobile phone (step S208).

  After the call ends, the driver's mobile phone disconnects the line with the base station by pressing the end call button of the mobile phone held by the passenger who is talking, and the Bluetooth between the passenger and the driver The connection is also disconnected (step S209).

  Next, another embodiment of the present invention will be described with reference to the flowchart of FIG. In this embodiment, the incoming call to the driver's mobile phone is a mail reception. First, when the driver's mobile phone receives the mail (step S301), it is determined whether or not the driver's mobile phone is set in the drive mode (step S302). It is determined whether the passenger of the vehicle driven by the vehicle holds a mobile phone that can be connected via Bluetooth (step S304), and if there is a connectable mobile phone, the passenger's mobile phone and the driver's mobile phone Are connected to the Bluetooth line, and the telephone number information is obtained from the passenger's mobile phone (step S305).

  Subsequently, the driver's mobile phone determines whether the acquired telephone number information of the passenger's mobile phone matches the connection condition (step S306). If the driver's mobile phone matches the connection condition, the driver's mobile phone The received mail is transferred to (step S307). The above connection condition is, for example, that the same telephone number as that of the passenger's mobile phone is stored in the phone book data storage unit of the driver's mobile phone. Thereafter, the driver's mobile phone automatically disconnects the Bluetooth connection with the passenger's mobile phone (step S308). In the case of mail reception, it is not necessary to establish a line with the base station as described above.

  If the driver's mobile phone is not set to the drive mode (No in step S302), there is no mobile phone that can be connected to the surroundings (no step S304), or the connection conditions are not met (step) In S306, the driver's mobile phone receives the same (ordinary) mail as before (step S303).

  Note that the present invention is not limited to the above embodiment. For example, in the above embodiment, the case where the Bluetooth function is used as the short-range communication means has been described. A distance communication means may be used. In addition, when incoming mail is received, there is no need to establish a line with the base station, so the mail data is simply transferred from the relay source mobile communication terminal to the relay destination mobile communication terminal using short-range communication means. Alternatively, it may be received and stored and then transferred.

  In addition, the relay function of the mobile communication terminal of the present invention may be set to relay or not for each incoming call and mail reception (for example, the incoming call is relayed, but the mail is not relayed, that is, forwarding) Not). Further, the relay function of the mobile communication terminal of the present invention is a telephone stored in the address book data storage section of the relay source mobile communication terminal as a limit of the relay destination of the incoming call so as not to transfer the incoming call to an unspecified number of people. The incoming call is transferred only to the mobile communication terminal having the number, but the telephone number may be a mail address or other identification code.

  In addition, the transition to the drive mode of the present invention may be set manually or automatically when the moving speed calculation means using a GPS (Global Positioning System) or the like exceeds a predetermined moving speed. It may be possible to make a transition. The partner terminal is not limited to the mobile phone 1 and may be a fixed phone or a portable information terminal having a telephone function other than the mobile phone.
