  The above object, other objects, features, and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

<First embodiment>
Referring to FIG. 1, mobile communication terminal 10 includes a CPU (sometimes called a processor or a computer) 20 and a key input device 22 that is an input device. The CPU 20 controls the radio communication circuit 14 corresponding to the CDMA system and outputs a call signal. The output call signal is transmitted from the antenna 12 and transmitted to the mobile communication network including the base station. Then, when the call partner performs a response operation, a call ready state is established.

  When a call end operation is performed by the key input device 22 after shifting to a call ready state, the CPU 20 controls the wireless communication circuit 14 to transmit a call end signal to the other party. Then, after transmitting the call end signal, the CPU 20 ends the call process. Also, when the call end signal is received from the call partner first, the CPU 20 ends the call process. Further, the CPU 20 ends the call process even when a call end signal is received from the mobile communication network regardless of the call partner.

  When a call signal from a call partner is captured by the antenna 12 while the mobile communication terminal 10 is activated, the wireless communication circuit 14 notifies the CPU 20 of an incoming call. Further, the CPU 20 controls the LCD monitor 26 which is a display device by the LCD driver 24, and displays the sender information described in the incoming call notification. Then, the CPU 20 outputs a ring tone from an incoming call notification speaker (not shown).

  In the call ready state, the following processing is executed. The modulated audio signal (high frequency signal) sent from the other party is received by the antenna 12. The received modulated audio signal is subjected to demodulation processing and decoding processing by the wireless communication circuit 14. The obtained received voice signal is output from the speaker 18. On the other hand, the transmission voice signal captured by the microphone 16 is subjected to encoding processing and modulation processing by the wireless communication circuit 14. Then, the generated modulated audio signal is transmitted to the other party using the antenna 12 as described above.

  Further, the CPU 20 can acquire information on the current position by a GPS (Global Positioning System) control circuit 32 and a GPS antenna 34 which are position information acquisition means. For example, when the user performs an operation to acquire current position information, the CPU 20 activates the GPS control circuit 32 and receives a GPS signal transmitted from the GPS satellite 100 by the GPS antenna 34. Then, the CPU 20 acquires the latitude and longitude of the current position from the received GPS signal.

  The mobile communication terminal 10 can execute a navigation function or the like using the received GPS signal. In FIG. 1, only one GPS satellite 100 is drawn for simplicity, but there are actually a plurality of GPS satellites 100. The current position information is acquired based on a plurality of GPS signals transmitted by a plurality of GPS satellites 100.

  Further, the mobile communication terminal 10 has a remote control function, and when the remote control function is executed, the CPU 20 functions as the remote control using the remote control circuit 36 and the infrared LED 38 that function as a transmission device. Let For example, when the user inputs an operation to remotely control an external device (hereinafter referred to as a remote control operation) to the key input device 22, the CPU 20 controls the remote control according to the remote control operation input to the key input device 22. A control signal transmission command is given to the control circuit 36. The remote controller control circuit 36 converts the control signal into an infrared signal based on the given transmission command, and transmits the infrared signal to the infrared LED 38. As a result, the external device converts the received infrared signal into a control signal, and changes the operating state in accordance with the converted control signal. For example, if the external device is illumination, power on / off is controlled in accordance with a remote control operation. If the external device is an air conditioner, power on / off and temperature adjustment are controlled in accordance with a remote control operation.

  Further, the infrared signal expresses binary data with infrared blinking at high speed, and the binary data represented by the infrared signal of the present embodiment includes a model code portion and a command portion. The model code portion includes a model code that identifies the type of external device, and differs depending on the external device operated by the remote control. The command unit includes a command (control signal) for controlling the external device, and includes, for example, a command (control signal) for controlling on / off of the power source. The external device does not accept the remote control operation unless the model code included in the received infrared signal is set in advance.

  Furthermore, the mobile communication terminal 10 is provided with a BT communication circuit 40 that performs short-range wireless communication in accordance with the Bluetooth (registered trademark) system. Short-distance wireless communication according to the Bluetooth method is performed. Users can connect and receive data such as image files and character string files to and from any external device by performing password-protected connection settings with any external device. Is possible.

  FIG. 2 is an illustrative view showing an appearance of the mobile communication terminal 10. Referring to FIG. 2, mobile communication terminal 10 has a case C1 formed in a plate shape. The microphone 16 and the speaker 18 (not shown in FIG. 2) are built in the case C1. The opening OP2 leading to the built-in microphone 16 is provided on one main surface in the length direction of the case C1, and the opening OP1 leading to the built-in speaker 18 is provided on the other main surface in the length direction of the case C1. That is, the user listens to the sound output from the speaker 18 through the opening OP1, and inputs the sound to the microphone 16 through the opening OP2.

  The key input device 22 includes a call key, an end key, a cursor key, a confirmation key, and numeric keys 0 to 9, and each key is provided on the main surface of the case C1. The LCD monitor 26 is attached so that the monitor screen is exposed on the main surface of the case C1.

  The user performs a response operation by operating the call key, and performs a call end operation by operating the call end key. In addition, the user operates a GUI (Graphical User Interface) with a cursor key or a numeric key, and confirms the result of the operation with a confirmation key. Also, the telephone number of the other party is input using the numeric keys 0-9. Then, the power-on / off operation of the mobile communication terminal 10 can be performed by long-pressing the end call key 22c. In addition, while the mobile communication terminal 10 is functioning as a remote controller, the user inputs a remote control operation using a cursor key and a confirmation key. For example, when the user turns on / off the power of the external device by remote control operation, the user switches on / off the power by pressing a confirmation key.

  Further, a window W1 leading to the infrared LED 38 is provided on one side surface in the length direction of the case C1. That is, the user performs a remote control operation with one side surface in the length direction of the case C1 facing the external device. The window W1 is fitted with a plastic that transmits infrared rays.

  Here, in the remote control function in the present embodiment, the external device can be operated by causing the mobile communication terminal 10 to function as a remote controller within a predetermined range. Specifically, in this remote control function, when a predetermined time set by the user is reached, information on the current position is acquired by receiving a GPS signal, and if it is within the range of the predetermined position, control for controlling the external device Send a signal. Thereby, the user can control the external device only by pointing the window W1 of the mobile communication terminal 10 toward the external device.

  First, the type of external device to be controlled, the predetermined time, and the initial setting of the predetermined position will be described using the GUI shown in FIG.

  FIG. 3 is an illustrative view showing one example of a GUI for performing initial setting in the remote control function. Referring to FIG. 3, LCD monitor 26 includes a status display area 50 and a function display area 52. In the status display area 50, the radio wave reception status by the antenna 12, the remaining battery capacity of the rechargeable battery, the current date and time, and the like are displayed. The current date and time displayed in the status display area 50 is acquired from the RTC 20a (time acquisition means) built in the CPU 20.

  Further, the function display area 52 displays a GUI for performing initial setting in the remote control function, and is operated using the key input device 22. In the GUI shown in FIG. 3, menus of “1. communication setting”, “2. automatic transmission setting”, “3. time setting”, “4. location registration” and “5. BT remote control registration” are shown. The numbers corresponding to the menus correspond to the numeric keys of the key input device 22, and the user can select an arbitrary menu by pressing the numeric keys.

  For example, when the user presses the number key “1”, the menu “1. Communication setting” can be selected. When the “1. communication setting” menu is selected, a GUI for setting the model code and the command included in the transmitted infrared signal is further displayed. For example, in setting the model code, the type of external device (manufacturer and model number such as lighting and air conditioner) can be selected. On the other hand, in the command setting, specific control contents such as power on / off can be selected. Thus, the user can arbitrarily determine the external device operated by the infrared signal. An external device operated by an infrared signal is widely used in general households, and an external device such as an illumination or an air conditioner can be easily operated using the mobile communication terminal 10 of the present invention.

  The user can select the menu “2. Automatic transmission setting” by pressing the “2” numeric key. When the “2. Automatic transmission setting” menu is selected, a GUI for setting whether to automatically transmit infrared signals (control signals) can be displayed. That is, the user can arbitrarily determine whether or not to automatically transmit the control signal.

  Further, when the user presses the number key “3”, the menu “3. Time setting” can be selected. When the menu of “3. Time setting” is selected, a GUI for setting a time for automatically transmitting a control signal is further displayed. The user can set an arbitrary time zone between 0 o'clock and 23:59. For example, the user can set the time zone for returning home as the predetermined time.

  Further, when the user presses the number key “4”, the menu “4. Location registration” can be selected. When the menu of “4. location registration” is selected, a GPS signal from the GPS satellite 100 is received, the latitude and longitude indicating the current position are acquired, and the acquired latitude and longitude are stored in the RAM 30 as predetermined positions. The range of the predetermined position in the remote control function is within a radius of 10 meters from the predetermined position. For example, if the user performs the initial setting of the position registration at the home H (see FIG. 5) within a radius of 10 mail, the home H falls within a predetermined position range. That is, the user can register the predetermined position at an arbitrary location such as in the home H.

  Then, when the user presses the numeric key “5”, the menu of “5. BT remote control registration” can be selected. Since the case where the menu of “5. BT remote control registration” is selected will be described later in the second embodiment, detailed description thereof is omitted here.

  Then, the illumination 60 which is an example of an external device is demonstrated. Referring to FIG. 4, illumination 60 includes a power supply circuit 62 that obtains power from an external power supply. A fluorescent lamp 64 is electrically connected to the power supply circuit 62, and the fluorescent lamp 64 emits light when a switch in the power supply circuit 62 is turned on. The infrared light receiving unit 68 including a light receiving sensor outputs an infrared signal to the control circuit 66 when receiving (receiving) an infrared signal. If the model code included in the infrared signal matches that set in advance, the control circuit 66 converts the infrared signal into a control signal and controls the power supply circuit 62. For example, in the case of a control signal for turning off the power, the switch in the power supply circuit 62 is turned off to turn off the fluorescent lamp 64. On the other hand, if the control signal is to turn on the power, the switch in the power supply circuit 62 is turned on in order to cause the fluorescent lamp 64 to emit light.

  It should be noted that the illumination 60 is not limited to turning on / off the power source, and the illuminance may be adjusted.

  Subsequently, in the initial setting of the remote control function, if the current position of the mobile communication terminal 10 is within the user's home H between 20 and 23:00, the control signal for turning on the illumination 60 is set to be transmitted. The case will be described. Referring to FIG. 5, lighting 60 is installed at the home H of the user. And when a user goes home between 20:00 and 23:00 with the portable communication terminal 10, the present position of the portable communication terminal 10 will be in the range of a predetermined position. At this time, the mobile communication terminal 10 transmits a control signal for turning on the illumination 60, that is, an infrared signal. Then, when the user points the window W1 of the mobile communication terminal 10 toward the infrared light receiving unit 68 of the illumination 60, the user can turn on the power of the illumination 60.

  That is, after returning to home H, the user can turn on the illumination 60 simply by pointing the mobile communication terminal 10 toward the illumination 60. Furthermore, since the user can set the time zone to go home so that the mobile communication terminal 10 does not receive GPS signals in an extra time zone, the power consumption of the mobile communication terminal 10 can be suppressed.

  Also, the mobile communication terminal 10 confirms whether or not it is the set predetermined time every minute, and if within the predetermined time, receives a GPS signal from the GPS satellite 100 every minute and Determine whether it is within range. And if it is in the range of a predetermined position, an infrared signal will be transmitted every 30 seconds. Further, when the infrared signal is transmitted every 30 seconds and the user performs a stop operation, the process of automatically transmitting the infrared signal is terminated. Note that a vibrator that is linked to the transmission of the infrared signal may be further provided, and the mobile communication terminal 10 may clearly notify the transmission of the infrared signal.

  FIG. 6 is an illustrative view showing a memory map of the RAM 30. Referring to FIG. 6, memory map 300 of RAM 30 includes a program storage area 302 and a data storage area 304. A part of the program and data is read from the flash memory 28 at a time or partially and sequentially as necessary, stored in the RAM 30, and processed by the CPU 20 or the like.

  The program storage area 302 stores a program for operating the mobile communication terminal 10. A program for operating the mobile communication terminal 10 includes a remote control function program 310 and a GPS communication program 312.

  The remote control function program 310 is a program for causing the mobile communication terminal 10 to function as a remote control, and further includes subroutines of an initial setting program 314 and an automatic transmission program 316. The initial setting program 314 is a program for performing an initial setting in the remote control function, and displays the GUI shown in FIG. The automatic transmission program 316 is a program for automatically transmitting a control signal based on the setting contents set by the processing of the initial setting program 314.

  The GPS communication program 312 is a program for receiving a GPS signal from the GPS satellite 100. In addition, although illustration is abbreviate | omitted, the program for operating the portable communication terminal 10 includes the program for performing a telephone call, etc.

  In the data storage area 304, an RTC buffer 320, a key operation buffer 322, and a GPS communication buffer 324 are provided. In the data storage area 304, model code pattern data 326, command pattern data 328, set time data 330, registered GPS data 332, and BT remote control data 334 data are stored, and an automatic transmission flag 336 is provided.

  The RTC buffer 320 temporarily stores time data read from the RTC 20a. In the key operation buffer 322, data indicating the key pressed by the key input device 22 is temporarily stored. The GPS signal received from the GPS satellite 100 is temporarily stored in the GPS communication buffer 324.

  The model code pattern data 326 is data indicating the pattern of the model code portion included in the infrared signal. The command pattern data 328 is data indicating the content of control by a command (control signal), and indicates the content of control for turning on / off the power, for example. The set time data 330 is data indicating a predetermined time set by the initial setting program 314. The registered GPS data 332 is data indicating a predetermined position registered by the initial setting program 314. The BT remote control data 334 is data indicating device information of the remote controller that is set for connection by short-range wireless communication according to the Bluetooth method.

  The automatic transmission flag 336 is a flag for determining whether or not automatic transmission of a control signal is set. For example, the automatic transmission flag 336 is composed of a 1-bit register. When the automatic transmission flag 336 is turned on (established), a data value “1” is set in the register. On the other hand, when the automatic transmission flag is turned off (not established), a data value “0” is set in the register.

  Although illustration is omitted, the data storage area 304 stores image data for displaying the GUI and the like, and is provided with other counters and flags necessary for the operation of the mobile communication terminal 10.

  Under the control of an RTOS (real-time operating system) such as “Linux” and “REX”, the CPU 20 executes a plurality of tasks including the initial setting process shown in FIG. 7 and the automatic transmission process shown in FIG. 8 in parallel. Execute.

  FIG. 7 is a flowchart showing the initial setting process. Referring to FIG. 7, when the user performs an operation for displaying the GUI shown in FIG. 3, CPU 20 determines whether or not communication settings have been made in step S <b> 1. That is, it is determined whether or not the “1. Communication setting” menu is displayed and set. If “NO” in the step S1, that is, if communication setting is not performed, the process proceeds to a step S5. On the other hand, if “YES” in the step S1, that is, if communication is set, the pattern of the control signal is stored in a step S3, and the process proceeds to the step S25. That is, in step S3, the type of the external device selected by the user is stored as model code pattern data 326, and the control content selected by the user is stored in the RAM 30 as command pattern data 328. The CPU 20 that executes the process of step S3 functions as a pattern setting unit.

  In step S5, it is determined whether automatic transmission has been set. That is, it is determined whether or not the “2. Automatic transmission setting” menu is displayed and set. If “NO” in the step S5, that is, if the automatic transmission setting is not set, the process proceeds to a step S9. On the other hand, if “YES” in the step S5, that is, if automatic transmission is set, the state of the automatic transmission flag 336 is switched in a step S7, and the process proceeds to the step S25. That is, the automatic transmission flag 336 is turned on if the control signal (infrared signal) is automatically transmitted, and the automatic transmission flag 336 is turned off if the control signal (infrared signal) is not automatically transmitted. .

  In step S9, it is determined whether time has been set. That is, it is determined whether or not the “3. Time setting” menu is displayed and set. If “NO” in the step S9, that is, if the time is not set, the process proceeds to a step S13. On the other hand, if the time is set in step S9, the time set in step S11 is stored. That is, the set time (predetermined time) is stored in the RAM 30 as the set time data 330. In addition, CPU20 which performs the process of step S11 functions as a time setting means.

  In step S13, it is determined whether location registration has been performed. That is, it is determined whether or not an operation for displaying a menu of “4. If “NO” in the step S13, that is, if the position is not registered, the process proceeds to a step S19. On the other hand, if “YES” in the step S13, that is, if the position is registered, information on the current position is acquired in a step S15. That is, the GPS communication program 312 is executed, a GPS signal is received from the GPS satellite 100, and information on the current position is acquired. Subsequently, in step S17, information on the current position is registered, and the process proceeds to step S25. That is, the current position (predetermined position) information acquired in step S15 is stored in the RAM 30 as registered GPS data 332. In addition, CPU20 which performs the process of step S17 functions as a position registration means.

  Here, since the processing of steps S19 to S23 will be described in a second embodiment described later, detailed description thereof will be omitted.

  In step S25, it is determined whether or not the operation is an end operation. For example, it is determined whether or not an end operation such as pressing an end call key of the key input device 22 has been performed. If “NO” in the step S25, that is, if the end operation is not performed, the process returns to the step S1. On the other hand, if “YES” in the step S25, that is, if an end operation is performed, the initial setting process is ended.

  FIG. 8 is a flowchart showing the automatic transmission process. That is, if the automatic transmission flag 336 is in an on state, the CPU 20 determines whether or not it is a set time in step S41. That is, it is determined whether or not the time temporarily stored in the RTC buffer 320 is within a predetermined time indicated by the set time data 330. In this way, the CPU 20 confirms whether or not it is within the set time, for example, transmits a control signal only in a dark time period, such as 6:00 pm to 5:00 am the next time, and turns on the power of the illumination 60. Control to turn on can be performed. If “NO” in the step S41, that is, if it is not the set time, the process of the step S41 is repeatedly executed every minute. On the other hand, if “YES” in the step S41, that is, if it is a set time, it is determined whether or not it is within the registered position range in a step S43. That is, the GPS communication program 312 is executed, and the current position information is acquired from the GPS signal. Then, it is determined whether or not the acquired current position information is included within a radius of 10 meters from the position indicated by the registered GPS data 322. If “NO” in the step S43, that is, if not in the registered position range, the process of the step S43 is repeatedly executed every minute.

  On the other hand, if “YES” in the step S43, that is, if it is within the registered position range, a control signal is transmitted in a step S45. That is, the CPU 20 determines a control signal based on the command pattern data 328. Then, the CPU 20 causes the remote control circuit 36 to convert the control signal into an infrared signal based on the model code pattern data 326 and to transmit the converted infrared signal from the infrared LED 38. Subsequently, in step S47, it is determined whether or not the operation is a stop operation. That is, it is determined whether or not an operation for stopping the infrared signal transmitted every 30 seconds has been performed. If “NO” in the step S47, that is, if it is not a stop operation, the processes of the steps S45 and S47 are repeatedly executed every 30 seconds. On the other hand, if “YES” in the step S47, that is, if it is a stop operation, the automatic transmission process is ended. Thus, CPU20 can suppress the power consumption of the mobile communication terminal 10 by transmitting an infrared signal intermittently.

  The automatic transmission process is terminated in response to the stop operation in step S47, but may be performed again after a certain time (12 hours). The CPU 20 that executes the process of step S45 functions as a transmission unit.

  Further, for example, when the illumination 60 is always installed in a dark place and the user always wants to turn on the illumination 60, the user can set the remote control function to 0 to 23:59 at the initial setting. You only have to set it. Thereby, the user can turn on the power of the illumination 60 only by going home with the mobile communication terminal 10 regardless of the time zone.

  Furthermore, although the cycle of transmitting the control signal (infrared signal) is set to every 30 seconds, if the mobile communication terminal 10 includes an optical sensor, the CPU 20 detects a change in ambient brightness from the output value of the optical sensor. Thus, intermittent transmission of the control signal may be stopped. Specifically, the determination content in step S47 may be determined as to whether or not the brightness has changed.

<Second embodiment>
In the second embodiment, a case will be described in which a BT remote controller 70 including a Bluetooth short-range wireless communication circuit is an external device. Specifically, if the mobile communication terminal 10 is wirelessly connected to the BT remote controller 70 within a predetermined position within a predetermined time, the mobile communication terminal 10 transmits a control signal in accordance with the Bluetooth method to the wirelessly connected BT remote controller 70. The power source of the illumination 60 is operated.

  In the second embodiment, a block diagram showing the configuration of the mobile communication terminal 10 in FIG. 1, an illustration showing the appearance of the mobile communication terminal 10 in FIG. 2, an illustration showing the initial setting GUI in FIG. 3, and FIG. The block diagram showing the configuration of the illumination 60, the illustrative diagram showing the memory map of the RAM 30 in FIG. 6, and the flowchart showing the initial setting process in FIG. 7 are the same as those in the first embodiment. Detailed description is omitted. In the second embodiment, the BT communication circuit 40 and the BT antenna 42 controlled by the CPU 20 function as a transmission device.

  First, the configuration of the BT remote controller 70 capable of operating the illumination 60 will be described with reference to FIG. Referring to FIG. 9, BT remote controller 70 includes a remote controller control circuit 72. The remote control circuit 72 is connected to an operation key 74, an infrared LED 76, and a BT communication circuit 78 having a BT antenna 80. The operation key 74 receives a remote control operation, and outputs an operation signal to the remote control circuit 72 in response to the input of the remote control operation. When an operation signal is input from the operation key 74, the remote control circuit 72 causes the infrared LED 76 to transmit an infrared signal corresponding to a preset control signal. The preset control signal is a control signal for turning on / off the power of the illumination 60.

  In addition, the BT antenna 80 outputs to the BT communication circuit 78 when receiving wireless communication data including connection information transmitted from the mobile communication terminal 10 and including password information. Then, the BT communication circuit 78 outputs password information to the remote control circuit 72, and the remote control circuit 72 confirms whether the password information matches that previously set. When the password information matches, the remote control control circuit 72 causes the BT communication circuit 78 to respond to the mobile communication terminal 10 that wireless connection is possible. As a result, the BT remote controller 70 is wirelessly connected to the mobile communication terminal 10 in accordance with the Bluetooth short-range wireless communication.

  Subsequently, when receiving a control signal for turning on the power from the wirelessly connected mobile communication terminal 10 through the BT antenna 80, the BT communication circuit 78 outputs the received control signal to the remote control circuit 72. Then, the remote control circuit 72 causes the infrared LED 76 to emit an infrared signal corresponding to the input control signal. Thereby, the power supply of the illumination 60 is turned on.

  Even if the mobile communication terminal 10 and the BT remote controller 70 are wirelessly connected and the wireless connection is released, the mobile communication terminal 10 and the BT remote control 70 Is automatically connected wirelessly.

  FIG. 10 is an illustrative view showing an appearance of the BT remote controller 70. Referring to FIG. 10, BT remote controller 70 has a case C2 formed in a plate shape. The operation key 74 is provided on one main surface in the length direction of the case C2. Further, a window W2 leading to the infrared LED 76 is provided on the other main surface in the length direction of the case C2. That is, the user inputs the remote control operation to the operation key 74 with the window W2 provided in the case C2 facing the illumination 60. Note that, similarly to the window W1, the window W2 is fitted with a plastic that transmits infrared rays.

  Here, the initial setting of the remote control function in the second embodiment will be described with reference to FIG. The menus of “3. Time setting” and “4. Location registration” are the same as those in the first embodiment, and thus detailed description thereof is omitted.

  First, in the second embodiment, when the “1. Communication setting” menu is selected, a GUI for selecting the content of a control signal to be transmitted to the BT remote controller 70 is displayed. For example, the user can select a control signal for turning on / off the illumination 60. Next, in the menu of “2. Automatic transmission setting”, whether or not to automatically transmit a Bluetooth control signal to the BT remote controller 70 can be set.

  When the “5. BT remote control registration” menu is selected, a GUI for wirelessly connecting the BT remote control 70 and the mobile communication terminal 10 is displayed. That is, when the menu of “5. BT remote control registration” is selected, the mobile communication terminal 10 detects the surrounding BT remote control 70 and displays a GUI for inputting a password on the LCD monitor 26. Then, the CPU 20 transmits wireless communication data including the input password information to the BT remote controller 70. At this time, if the input password is correct, a wireless connection between the BT remote controller 70 and the mobile communication terminal 10 is established. Further, the device information of the wirelessly connected BT remote controller 70 is stored in the RAM 30. As a result, the user can freely register information on the external device to be wirelessly connected by short-range wireless communication. The user can operate the external device using short-range wireless communication, which is less affected by obstacles than infrared signals.

  The menu of “1. Communication setting” in the second embodiment is a control signal to be transmitted to the BT remote controller 70 only when the device information of the BT remote controller 70 is stored in the “5. BT remote controller registration” menu. A GUI for selecting contents is displayed. In other words, if the device information of the BT remote controller 70 is not erased or stored, the GUI for setting the model code and the command included in the infrared signal described in the first embodiment is displayed. Also, the short-range wireless communication standard is not limited to the Bluetooth system, but may be a wireless LAN, for example, a short-range wireless communication standard of the Wi-Fi system.

  Here, if the mobile communication terminal 10 and the BT remote control 70 are wirelessly connected in the initial setting of the remote control function, and the range of the current position of the mobile communication terminal 10 is between 20 and 23:00, it is the user's home H. A case where the BT remote controller 70 is set to transmit a control signal for turning on the power of the illumination 60 will be described. Referring to FIG. 11, similarly to the first embodiment, an illumination 60 is installed on the ceiling of the user's home H. The BT remote controller 70 is placed at home H in a state where an infrared signal to be transmitted reaches the infrared light receiving unit 68 of the illumination 60.

  When the user returns home between 20:00 and 23:00, the current position of the mobile communication terminal 10 falls within a predetermined position range. At this time, when the mobile communication terminal 10 is wirelessly connected to the BT remote controller 70, the mobile communication terminal 10 transmits a control signal for turning on the illumination 60 to the BT remote controller 70. And BT remote control 70 transmits the infrared signal which turns on the power supply of the illumination 60 based on the received control signal. Thereby, the user can turn on the power of the illumination 60 only by returning home in a predetermined time. Further, the user can turn on the illumination 60 with the mobile communication terminal 10 in the bag or pocket.

  Note that the timing for confirming whether or not the predetermined time is within the range of the predetermined position is the same as that in the first embodiment. The timing for transmitting the control signal is every 30 seconds as in the first embodiment. Further, as in the first embodiment, a vibrator that interlocks with the transmission of the control signal may be provided.

  The CPU 20 in the second embodiment also executes a plurality of tasks in parallel including the initial setting process shown in FIG. 7 and the automatic transmission process shown in FIG. 12 under the control of the RTOS such as “Linux” and “REX”. . In the initial setting process in the second embodiment, the processes in steps S1, S5-S17, and S25 are the same as those in the first embodiment, and thus the description thereof is omitted. Also, in the automatic transmission process of the second embodiment shown in FIG. 12, the processes in step S41, step S43, and step S47 are the same as those in the first embodiment, and detailed description thereof is omitted.

  First, referring to FIG. 7, if “YES” in the process of step S <b> 1, the CPU 20 of the second embodiment stores a control signal pattern in step S <b> 3. That is, the type of control signal (command) to be transmitted is stored in the RAM 30 as command pattern data 328.

  If “NO” in the step S13, it is determined whether or not the BT remote control is registered in a step S19. That is, it is determined whether or not an operation for displaying a menu of “5. BT remote control registration” has been performed. If “NO” in the step S19, that is, if BT remote control registration is not performed, the process proceeds to a step S25. On the other hand, if “YES” in the step S19, that is, if the BT remote controller is registered, the initial setting of the BT remote controller 70 is performed in a step S21. That is, the wireless connection with the BT remote controller 70 is established based on the input password. Subsequently, in step S23, information of the BT remote controller 70 is stored, and the process proceeds to step S25. That is, the device information of the BT remote controller 70 is stored in the RAM 30 as the BT remote controller data 334.

  Next, referring to FIG. 12, if “YES” in the step S43, the CPU 20 of the second embodiment wirelessly connects to the BT remote controller 70 in a step S61. That is, the wireless connection with the BT remote controller 70 wirelessly connected by the initial setting is established. Subsequently, in step S63, a control signal is transmitted to the BT remote controller 70, and the process proceeds to step S47. That is, a control signal is transmitted to the BT remote controller 70 based on the command pattern data 328.

  The automatic transmission process in the second embodiment may be terminated without executing the process of step S47 after transmitting the control signal in step S63. In addition, when the wireless connection with the BT remote controller 70 cannot be established in step S61, the short-range wireless communication for performing the wireless connection may be performed every 30 seconds. In addition, a wireless connection with the illumination 60 including the BT communication circuit may be established and a remote control operation may be performed. The CPU 20 that executes the process of step S63 functions as a transmission unit.

  As can be understood from the above description, the mobile communication terminal 10 includes the remote control circuit 36, the infrared LED 38, the BT communication circuit 40, and the BT antenna 42, and can transmit a control signal (infrared signal) to an external device. it can. Furthermore, the mobile communication terminal 10 includes a GPS control circuit 32 and a GPS antenna 34, and can acquire information on the current position. Further, the user can acquire information on the current position at the center of the home H or the like and register the inside of the home H as a range of a predetermined position by initial setting of the remote control function. When the user returns to the home H with the mobile communication terminal 10, since the information on the current position of the mobile communication terminal 10 is included in the home H, the mobile communication terminal 10 includes the illumination 60 (or the BT remote controller 70). The illumination 60 can be turned on by transmitting an infrared signal (control signal).

  As a result, the user can control the power supply of the illumination 60 and the like only by going to (returning to) an arbitrary place registered in advance.

  Note that the fluorescent lamp 64 included in the illumination 60 may be another light emitting device such as an LED illumination or an organic EL illumination. Further, the radius of 10 meters in the predetermined position range may be another value. Furthermore, the range of the predetermined position may be arbitrarily changed by the user. The external device controlled by the control signal (infrared signal) that is automatically transmitted is not limited to the illumination 60 but may be an air conditioner such as an air conditioner or a fan, a television, a radio, or the like.

  In the BT remote controller 70, the model code of the infrared signal to be transmitted may be arbitrarily set by the user. Further, the BT remote controller 70 whose model code can be arbitrarily set by the user may be sold as a set with the mobile communication terminal 10 or may be sold separately as an optional product.

  Further, the communication system of the mobile communication terminal 10 is not limited to the CDMA system, but may be a W-CDMA system, a TDMA system, a PHS system, or the like. Moreover, not only the portable communication terminal 10, but a portable game machine, a portable music player, a notebook PC, a PDA (Personal Digital Assistant), or the like may be used.

  In another embodiment, if the mobile communication terminal 10 includes an acceleration sensor, it is determined from the acceleration value output by the acceleration sensor whether the mobile communication terminal 10 is being carried. It may be determined whether or not it is within the range of the predetermined position only when the is carried. Specifically, a process for determining whether or not the mobile communication terminal 10 is carried based on the acceleration value output by the acceleration sensor is newly added between step S41 and step S43. If “YES” is determined in the process, the process of step S43 may be performed. As a result, the number of times of confirmation of the current position using the GPS control circuit 32 with high power consumption can be reduced. That is, the CPU 20 can suppress the power consumption of the mobile communication terminal 10 by adding the above processing.
