  For example, if you need emergency contact with your workplace or visiting place due to delays in public transportation, if your contact phone number or email address is registered in your mobile phone memory but you don't remember it Unless you have a mobile phone, you will not be able to get in touch.

  As a means for solving this, a method of remotely operating a mobile phone can be considered. However, since the conventional technology focuses on the misplacement of mobile phones, most of them lock the functions of mobile phones to protect personal information and use them to use information in mobile phones. There is little that can be done. In this regard, a technique of using a mobile phone by remote control is also known (see, for example, Patent Documents 1 to 4).

  For example, Patent Document 1 describes a mobile phone control system that can automatically make a call from a mobile phone of an information terminal according to a remote operation from a control station with only a simple operation such as pressing a button once.

  Patent Document 2 describes a remote control system that performs remote control of a controlled device by using a mobile phone without changing the hand.

  Also, in Patent Document 3, it is determined whether or not remote access to the terminal is permitted, and when it is determined to be permitted, information browsing in the terminal and updating of an incoming response message in response to a request from an external network A mobile phone device is described.

  Furthermore, Patent Document 4 describes a mobile communication terminal that can obtain information in portable electricity by remote control even when a cellular phone is left at home.

  A user connects to the mobile phone 101 to be operated through a mobile phone network or the Internet network using a remote control communication means (mobile phone 103, fixed phone 104, PC 106). As connection means in this case, two types of connection, voice connection and packet connection, can be taken.

  First, when connecting by voice, a DTMF (Dual-Tone Multi-Frequency) from a connection source terminal (in the example of FIG. 1, the mobile phone 103 or the fixed phone 104 used as a communication means to the mobile phone 101 to be operated). Signals are used to directly control operation signals (control information related to key operations of the mobile phone 101 and functions in the mobile phone 101) to a connection destination terminal (in the example of FIG. 1, the target mobile phone 101). Control information). The DTMF signal is composed of 16 types of codes “0” to “9”, “*”, “#”, “A” to “D” assigned to the keys of the operation unit, and the low group frequency. And it transmits as a synthetic sound of two audio | voice signals of high group frequency. The connection source terminal (mobile phone 103 and fixed phone 104) and the connection destination terminal (mobile phone 101) used in this embodiment transmit and receive a preset operation signal using a DTMF signal by the operation of each unit described above. The operation according to the operation signal is performed.

  Upon receiving the DTMF signal, the connection destination terminal performs an operation according to the operation signal transmitted as the DTMF signal, and announces the result and the operation content that can be selected in the next operation to the connection source terminal by voice. . Here, the content of the voice (voice message) announced from the connection destination terminal to the connection source terminal is stored in advance in a storage unit such as a memory on the connection destination terminal in association with the operation signal by the DTMF signal.

  Next, when connecting with a packet, it is connected to the mobile phone 101 which is a connection destination terminal through an Internet line, and control information related to key operations of the mobile phone 101 and control information for directly controlling functions in the mobile phone 101. The AT command is transmitted on the packet data. The AT command is one of command systems used for controlling a communication device such as a modem or a terminal adapter (TA). The AT command is used when a command (used when instructing an operation from the terminal to the communication device), an S register ( This register stores parameters that define the automatic incoming call operation and is referred to when executing a command), and a result code (report of command execution result, incoming report, etc.). A connection source terminal such as the PC 106 used in the present embodiment that can be used on the Internet transmits and receives an operation signal set in advance using such an AT command, and performs an operation according to the operation signal.

  The connection destination terminal (mobile phone 101) that has received the packet data carrying the AT command places the execution result of the AT command and the screen data of the mobile phone 101 at that time on the packet data and returns it to the connection source terminal. Upon receiving this, the connection source terminal displays the received screen data of the mobile phone 101 on the screen of the connection source terminal, and then prompts the user for the next operation.

  Next, the operation of the present embodiment will be described.

  First, referring to FIG. 2, a voice remote operation starting method using the mobile phone 103 or the fixed phone 104 of FIG. 1 as a connection source terminal will be described.

  The user uses the mobile phone 103 or the fixed phone 104 that is the connection source terminal to make a call to the connection destination telephone number of the mobile phone 101 that is the connection destination terminal via the mobile phone network (step S201). When the connection destination terminal (mobile phone 101) responds, the user transmits a DTMF signal from the connection source terminal to the connection destination terminal and calls a remote operation menu (step S202). The remote operation menu is stored in advance in a storage unit such as a memory on the connection destination terminal side in association with an operation signal by a DTMF signal.

  When the remote operation menu is entered, a password (password) is first input to prevent unauthorized use (step S203). When the user inputs a password using a DTMF signal, the connection destination terminal checks whether the input password is valid (step S204).

  If the password is entered incorrectly, the user is prompted to enter the password again. If the password is entered incorrectly for a certain number of times, the remote operation menu is terminated and the call is disconnected (steps S205 to S206). If the password is valid (step 204: Yes), the user gives guidance that the user has connected to the remote operation menu and can use it (steps S207 to S208).

  After the remote operation menu is connected, a key operation corresponding to a function that can be used in the guidance is announced to the connection source terminal by voice, and a DTMF signal is transmitted by performing the key operation according to the guidance content (step S209). The connection destination terminal that has received the DTMF signal performs the corresponding operation and responds with a result of the voice response (step S211).

  When the remote operation is terminated, a corresponding DTMF signal is transmitted, and the connection destination terminal receiving the signal disconnects the call (steps S210 and S206). The key to be pressed at this time is announced to the user in advance by guidance.

  Next, FIG. 3 shows a remote operation method using packet communication. The user performs packet connection from a connection destination terminal such as the PC 106 of FIG. 1 that can use the Internet via the Internet network and the mobile phone network to the mobile phone 101 that is the connection destination terminal, and calls a remote operation menu (step S1). S301 to S302). At this time, as means for starting packet communication, for example, SMS (Short Message Service), mail including control information, or the like is used.

  After the packet connection, as in the case of the voice connection, the state is changed to a state where remote control is possible only when a correct password is input (steps S303 to S307). When using packet connection, information such as an image can be transmitted on the packet data. When the connection is completed, the screen of the connection destination terminal is displayed (step S308).

  After the remote operation is enabled, the user operates the connection destination terminal via the connection source terminal. The operation content is placed on the packet data as an AT command, and the packet data is transmitted to the connection destination terminal, thereby operating the connection source terminal (step S309).

  The connection destination terminal that has received the packet data performs the operation specified by the AT command, and returns the subsequent operation result and the screen data after the operation on the packet data (step S311). When the operated operation is a content indicating the end of the remote operation, the packet line is disconnected (steps S310 and S306).

  Therefore, according to the present embodiment, the following effects can be achieved.

  (1) Since the phone book data stored in the mobile phone can be referred to even when the mobile phone is not at hand, for example, when the mobile phone 107 is left behind at home, the user goes out (accidents and traffic troubles). When contact is required, even if the contact phone number is unknown, the contact can be confirmed from the public phone or the cellular phone 103 of the friend who is accompanying the phone.

  (2) By using the three-party calling function in the mobile phone, the telephone directory of the mobile phone 101 is called from the general telephone line of the fixed phone 104 such as a public phone, and the public phone is called by calling from the mobile phone 101. It is also possible to make a call from the mobile phone 101 via the mobile phone 101 to the mobile phone 107 (see FIG. 1), which is a call destination terminal (see FIG. 4: steps S401 to S405).

  FIG. 4 illustrates an operation in the case where voice communication is performed by remote operation using the three-party call function by the mobile terminal remote control system shown in FIG. In FIG. 4, as described above, after the remote operation connection is made from the fixed telephone 104 as the connection source terminal to the mobile phone 101 as the connection destination terminal (step S401), the connection from the connection source terminal to the mobile phone 101 by voice communication using the DTMF signal. By sending control information for directly controlling the three-party call function to the destination terminal, voice is transmitted from the destination terminal to the destination terminal (step S402), thereby the three parties at the destination terminal, the destination terminal, and the source terminal. A call is made (step S403), and after the call with the destination terminal is finished (step S404), the remote operation is finished (step S405).

  (3) In the implementation method in the form using packet communication, when the mobile phone is lost, the position is remotely measured by GPS mounted on the mobile phone and transmitted to the connection source terminal by e-mail, or It is possible to search by a method such as activating a camera of a mobile phone and checking surrounding images.

  For example, when you forget your mobile phone at home and want to go out, you need to refer to your contacts and schedules, such as your phone book or email address, or contact by phone or email. Or, when the mobile phone is lost, it can be maximized when searching using the GPS function or camera function built into the mobile phone.

  In the present embodiment, the connection source and the connection destination are directly connected by voice remote operation. However, in actual use, the user provides a service provided by a business operator such as an answering machine. Often used. In this case, if the connection destination terminal does not answer within a certain ringing time, it is connected to the answering machine service in the carrier network. Therefore, in order to automatically answer the connection destination terminal, the answering machine service is temporarily suspended in advance. After stopping, it is necessary to change the setting to automatically answer after calling for a certain period of time, which is not convenient.

  Therefore, a remote control function is provided in the mobile phone network, and the user sends a special number (a specific number prepared for remote control + the phone number of the connection destination terminal), connects to the mobile phone network, and connects to the connection destination terminal. Can be considered to respond via a call from the mobile phone network. In addition, in the case of this usage mode, the response message, the configuration of the usage menu, etc. can be updated by changes on the network side, so there is no need to hold voice messages on the connected terminal side, without making changes to the terminal Flexible operation, such as changing the menu structure and usage functions, is possible.

  In this embodiment, the packet source is directly connected to the connection source terminal and the connection destination terminal by remote control with a packet. However, password authentication with the connection destination terminal, connection with the connection destination terminal, etc. Such an embodiment is also possible in which the functions are implemented by the Internet server 105 (see FIG. 1) on the Internet network side and the cellular phone server 102 (see FIG. 1) on the cellular phone network side.

  In this embodiment, the data to be put in the packet is described as only AT command and mobile phone screen data. However, the data to be put in the packet is not limited to these, and various data is packetized and transmitted / received. There can be.

  In this case, you can make a call from the connection destination terminal by remote control and send / receive voice data to / from the other party as packet data between the connection source terminal and the connection destination terminal. Sending a mail to a mobile phone that refuses to receive mail from other than a mobile phone by using the other party to make a call or creating and sending a mail by remote control from the connection source terminal It is possible (see FIG. 5: steps S501 to S504), and the mobile site 108 (see FIG. 1) that can be browsed only from a mobile phone can also be browsed on the connection source terminal (FIG. 6: step). (See S601 to S603).
