Description

  The present invention relates to a method for controlling an electronic device including a receiving unit capable of receiving a signal conforming to a signal standard of a satellite signal from a positioning satellite.

  Mobile communication terminals that transmit and receive radio waves, such as mobile phones and PHS (Personal Handy-phone System), have a manner mode function that limits ringtones for calls and mails. Manner mode plays an important role in preventing the surrounding people from being inconvenienced in public spaces such as movie theaters and museums where quietness is required.

  Further, since the mobile communication terminal transmits and receives radio waves even in the manner mode, in transportation such as trains and buses, an announcement for requesting power-off of the mobile communication terminal is played near the priority seat. In consideration of the influence on the aircraft control equipment and medical equipment, the power source of the mobile communication terminal is required to be cut off even in aircraft and hospitals. However, usually the manner mode setting and the power-off must be manually performed by the user, and are often forgotten.

  In order to solve such a problem, for example, in Patent Document 1, a gate having a transmitter is installed at an entrance / exit of a manner area such as a train or a building, and a mode switching signal is transmitted to a mobile communication terminal that has passed the gate. A technique for automatically setting a mobile communication terminal to a manner mode by transmitting “” is disclosed.

  In the technique disclosed in Patent Document 1, the mode of the mobile communication terminal is switched by managing a flag for entrance / exit determination. That is, when the mobile communication terminal receives a mode switching signal transmitted from the gate with the flag set to OFF, the mobile communication terminal determines that it has entered the manner area and forcibly enters the manner mode. Switching control is performed. In this technology, when a user carrying a mobile communication terminal temporarily passes the vicinity of the gate, the mobile communication terminal accidentally receives the mode switching signal, and the manner mode is unexpectedly set. Could cause problems.

Furthermore, as long as the electronic device is located within the signal reachable range, even if the user manually returns the operating state of the electronic device to the operating state before the control, the electronic device is controlled again. There is no end to hard work. In addition, since the electronic device located within the signal reachable range can be spatially monitored and controlled, it is possible to prevent a control signal reception error from occurring and increase the reliability of control of the electronic device.

  If the received signal includes position information, the mobile phone can estimate the position of the mobile phone using the position information. In addition, for example, by placing a signal transmission device in a facility where quietness is required, the answering function of a mobile phone located in the facility can be turned on uniformly. Then, by making an answering machine response message containing information about the location information contained in the received signal, the other party who called the mobile phone answers the location where the user of the mobile phone is located and the phone It's convenient because you can know why you can't.

  Hereinafter, an example of a preferred embodiment of the present invention will be described with reference to the drawings. However, embodiments to which the present invention can be applied are not limited to the embodiments described below.

1. System Configuration FIG. 1 is a diagram illustrating a schematic configuration of a control system 1 that is an example of a system that controls a mobile phone that is a type of electronic apparatus. The control system 1 includes a mobile phone 3, a plurality of GPS satellites 5, and a plurality of pseudo satellites 7.

  The mobile phone 3 is an electronic device as a mobile communication terminal for a user to perform a call or mail transmission / reception, etc. In addition to the original function as a mobile phone such as a call or mail transmission / reception, a function for calculating a position The position calculation apparatus which comprises is comprised. The mobile phone 3 calculates a position based on a GPS satellite signal transmitted from the GPS satellite 5 or a pseudo satellite signal transmitted from the pseudo satellite 7, and displays a position display screen on which the calculated position is plotted. By displaying on the screen, the current position is notified to the user.

  The GPS satellite 5 is a kind of positioning satellite, and four or more satellites are arranged on each of the six orbiting planes of the earth. In principle, four or more satellites are always geometrically located from anywhere on the earth. It is operated so that it can be observed. The GPS satellite 5 transmits navigation data such as almanac and ephemeris in a GPS satellite signal. The GPS satellite signal is a 1.57542 [GHz] communication signal modulated by a direct spread spectrum system with a PRN (Pseudo Random Noise) code which is a unique modulation code assigned to each GPS satellite 5. The PRN code is a pseudo-random noise code having a repetition period of 1 ms with a code length of 1023 chips as one PN frame.

  The pseudo-satellite 7 is a kind of transmitting device, and is arranged everywhere in a facility such as a building, and always transmits a pseudo-satellite signal including information on the arrangement position. The pseudo satellite signal transmitted from the pseudo satellite 7 is a communication signal simulating a GPS satellite signal transmitted from the GPS satellite 5, and the transmission frequency is 1.57542 [GHz], which is the same as the GPS satellite signal. That is, the pseudo satellite 7 is configured to transmit a pseudo satellite signal compliant with the signal standard (communication standard) of the GPS satellite signal from the GPS satellite 5. Although the GPS satellite signal and the pseudo satellite signal have the same signal standard, the assigned PRN code is different between the GPS satellite 5 and the pseudo satellite 7.

  FIG. 2 is a diagram illustrating PRN code assignment. Thirty-two PRN codes “1” to “32” are assigned to the GPS satellite 5. On the other hand, ten PRN codes “173” to “182” are assigned to the pseudo satellite 7. Due to such a difference in PRN code assignment, the mobile phone 3 can easily identify whether the received satellite signal is a GPS satellite signal or a pseudo-satellite signal.

  In the present embodiment, the pseudo satellite 7 transmits information related to the arrangement position such as the latitude, longitude, altitude, and floor information of the position where the pseudo satellite 7 is arranged in its own pseudo satellite signal. Further, the pseudo satellite 7 transmits ID (IDentification), which is a kind of control code, as its additional information in its pseudo satellite signal. In the present embodiment, this ID functions as an ID (hereinafter referred to as “control ID”) for giving a control instruction from the outside to the mobile phone 3. Note that the pseudo-satellite signal included in the pseudo-satellite signal and transmitted does not have to be one type, and a plurality of types of control IDs may be included in the pseudo-satellite signal and transmitted.

  The pseudo-satellite 7 has a transmission signal intensity such that a pseudo-satellite signal reachable range (hereinafter referred to as a “signal reachable range”) is a specified distance (for example, a radius of 10 m centered on the position of the pseudo-satellite 7). Etc. are designed in advance. Since the signal reachable range has a spatial spread, it is spatially monitored whether or not the mobile phone 3 is located in the signal communication area, and the mobile phone 3 located in the signal communication area is The operation can be controlled uniformly.

  When the mobile phone 3 detects that the pseudo satellite signal transmitted from the pseudo satellite 7 has been received, the mobile phone 3 continuously receives the pseudo satellite signal (hereinafter referred to as “continuous reception time”). Measure. Then, whether or not the measured continuous reception time has reached a predetermined elapsed time (for example, 10 seconds; hereinafter described as “first predetermined elapsed time”) is set as a reception condition of the pseudo satellite signal. judge. And when it determines with having reached | attained, an own machine is controlled according to the control content matched with control ID contained in the said pseudo | simulation satellite signal. In other words, when the continuous reception time of the pseudo satellite signal satisfies a predetermined continuous reception condition, the own device is controlled based on the control ID included in the pseudo satellite signal.

  FIG. 3 is a diagram illustrating an example of a data configuration of the external instruction operation control data 805 that defines the correspondence between the control ID and the control content. In the external instruction operation control data 805, a control ID 8051, a target function 8053 that is a function of the mobile phone 3 to be controlled, and control contents 8055 for the target function 8053 are stored in association with each other.

  For example, for the control ID “1”, the target function “power supply” and the control content “disconnect” are associated with each other. The mobile phone 3 that has continuously received the pseudo-satellite signal including “1” as the control ID controls to turn off its own power supply. Similarly, for the control ID “2”, the target function “call” is associated with the control content “suppression”. The mobile phone 3 that has continuously received the pseudo satellite signal including “2” as the control ID performs control so as to suppress the call function of its own device.

  In addition, for example, for the control ID “3”, the target function “mail transmission / reception” is associated with the control content “suppression”, and for the control ID “4”, the control is performed with the target function “Internet connection”. The content “suppression” is associated. For the control ID “6”, the target function “auto answering function” is associated with the control content “ON”, and for the control ID “7”, the target function “incoming mode” and the control content “ “Manner mode” is associated.

  When the automatic answering machine detects that an incoming call has been received from another telephone, it sends a response message to the caller's telephone indicating that it cannot answer the call and also records a message from the user of the caller's telephone. It is a function to do. In silent mode, the user of the telephone is notified by other means such as vibration (vibration) without receiving a ring tone or receiving a call or mail from another telephone. Is a mode that makes the sound smaller than the normal mode.

  In the present embodiment, the pseudo-satellite 7 is used for portable communication such as a facility such as a movie theater or an art museum where quietness is required, a concert hall or a theater hall, a priority seat such as a train or a bus, a hospital, or an aircraft cabin. As many devices as necessary are arranged at the density required, where the devices are required to be turned off or set to silent mode. Then, the pseudo satellite 7 gives a control instruction via the control ID to the mobile phone 3 included in the signal reachable range of the pseudo satellite signal transmitted by itself, and is carried in accordance with the control content corresponding to the facility or place. The model telephone 3 is controlled by itself.

  For example, FIG. 1 shows an example in which a pseudo satellite 7 is arranged in a facility where a live is held (hereinafter referred to as “live facility”). In FIG. 1, the live facility is divided into three places, an entrance hall, a lobby, and a live venue, in order of proximity to the outdoors, and a pseudo satellite signal including a different control ID is transmitted to each place. A satellite 7 is arranged.

  In the entrance hall, a pseudo-satellite 7a for transmitting a control ID (for example, control ID “10” in FIG. 3) for controlling the ringing volume of the mobile phone 3 to the minimum is arranged. In the lobby, a pseudo satellite 7b for transmitting a control ID (for example, control ID “7” in FIG. 3) for controlling the incoming mode of the mobile phone 3 to change to the manner mode is arranged. In the live venue, a pseudo satellite 7c that transmits a control ID (for example, control ID “1” in FIG. 3) for controlling the mobile phone 3 to be turned off is disposed.

  1, the user carrying the mobile phone 3 enters the entrance hall from outside and the mobile phone 3 starts receiving the pseudo satellite signal transmitted from the pseudo satellite 7a. When the first specified elapsed time has elapsed, the mobile phone 3 controls to minimize the ring volume. When the user completes the reception and enters the lobby, and the mobile phone 3 starts receiving the pseudo satellite signal transmitted from the pseudo satellite 7b, the mobile phone 3 Change the incoming mode to manner mode. Then, when the user opens the door and enters the live venue from the lobby and the mobile phone 3 starts receiving the pseudo satellite signal transmitted from the pseudo satellite 7c, The telephone 3 is controlled to turn off the power.

  One characteristic of the present embodiment is that when a pseudo satellite signal is continuously received for the first specified elapsed time, control based on the control ID included in the pseudo satellite signal is performed. is there. That is, even if the mobile phone 3 temporarily receives the pseudo satellite signal, the mobile phone 3 does not control the own device by itself, but controls the own device only after receiving the pseudo satellite signal for a predetermined time or more. It is. Thereby, when the portable telephone 3 is accidentally included in the signal reachable range of the pseudo satellite 7, it is possible to prevent the occurrence of a situation in which the own device is unexpectedly controlled.

  On the other hand, when a predetermined elapsed time (for example, 20 seconds, hereinafter described as “second specified elapsed time”) elapses after the mobile phone 3 stops receiving the pseudo-satellite signal, the pseudo-satellite signal The operation state of the own device changed by the control based on the control ID included in the operation ID is returned to the operation state before the control. That is, when the continuous reception of the pseudo satellite signal is interrupted, the operation state of the own device is restored to the operation state before the control. For example, it is assumed that the incoming mode is changed from the normal mode to the manner mode based on the pseudo satellite signal. In this case, when the second specified elapsed time has elapsed since the pseudo satellite signal is no longer received, the mobile phone 3 returns the incoming call mode from the manner mode to the normal mode.

2. Functional Configuration FIG. 4 is a block diagram showing a functional configuration of the mobile phone 3. The mobile phone 3 includes a GPS antenna 9, a GPS receiving unit 10, a host CPU (Central Processing Unit) 30, an operation unit 40, a display unit 50, a mobile phone antenna 60, and a mobile phone wireless communication circuit. And a flash ROM (Read Only Memory) 80 and a RAM (Random Access Memory) 90.

  The GPS antenna 9 is an antenna that receives an RF (Radio Frequency) signal including a GPS satellite signal transmitted from a GPS satellite, and outputs the received signal to the GPS receiving unit 10.

  The GPS receiver 10 is a position calculation circuit that measures the position of the mobile phone 3 based on a signal output from the GPS antenna 9 and is a functional block corresponding to a so-called GPS receiver. The GPS receiving unit 10 includes an RF (Radio Frequency) receiving circuit unit 11 and a baseband processing circuit unit 20. The RF receiving circuit unit 11 and the baseband processing circuit unit 20 can be manufactured as separate LSIs (Large Scale Integration) or can be manufactured as one chip.

  The RF receiving circuit unit 11 is an RF signal processing circuit block, and generates an oscillation signal for RF signal multiplication by dividing or multiplying a predetermined oscillation signal. Then, by multiplying the generated oscillation signal by the RF signal output from the GPS antenna 9, the RF signal is down-converted to an intermediate frequency signal (hereinafter referred to as “IF (Intermediate Frequency) signal”), and IF After amplifying the signal, it is converted into a digital signal by an A / D (Analog Digital) converter and output to the baseband processing circuit unit 20.

The baseband processing circuit unit 20 includes a satellite capturing unit 21 that captures GPS satellite signals and pseudo satellite signals, a CPU 23 as a processor, and a ROM 25 and a RAM 27 as memories. In addition, the satellite capturing unit 21 includes a correlation calculation unit 211 and a replica code generation unit 213.

  The correlation calculation unit 211 calculates the correlation between the PRN code of the IF signal output from the RF reception circuit unit 11 and the replica code generated by the replica code generation unit 213 using, for example, FFT (Fast Fourier transform) calculation. Then, a correlation calculation process is performed, and the GPS satellite signal and the pseudo satellite signal are captured. The replica code is a signal simulating the PRN code of the GPS satellite signal and pseudo satellite signal to be captured.

  If the satellite signal to be acquired is correct, the PRN code and the replica code included in the satellite signal match (capture success), and if they are incorrect, they do not match (capture failure). Therefore, by determining the peak of the calculated correlation value, it can be determined whether or not the acquisition of the satellite signal was successful, and by changing the replica code one after another and performing the correlation operation with the same received signal, the satellite The signal can be captured.

  In addition, the correlation calculation unit 211 performs the above-described correlation calculation process while changing the frequency and phase of the replica code generation signal. When the frequency of the generated signal of the replica code matches the frequency of the received signal and the phases of the PRN code and the replica code match, the correlation value becomes maximum.

  More specifically, a predetermined frequency and phase range corresponding to the satellite signal to be captured is set as the search range. Then, within this search range, correlation calculation in the phase direction for detecting the start position (code phase) of the PRN code and correlation calculation in the frequency direction for detecting the frequency are performed. The search range is determined within a predetermined frequency sweep range centering on the search frequency in consideration of the error of the transmission frequency, and the phase is within the code phase range of 1023 chips that is the chip length of the PRN code.

  The CPU 23 is a processor that performs overall arithmetic processing by controlling each part of the baseband processing circuit unit 20 to the RF receiving circuit unit 11, and controls the satellite capturing unit 21 and satellites captured by the satellite capturing unit 21. Processes such as signal demodulation.

  6 and 7 are diagrams showing a flow until data is extracted from the satellite signal. FIG. 6 is an explanatory diagram for a GPS satellite signal, and FIG. 7 is an explanatory diagram for a pseudo satellite signal. The GPS satellite signal will be described. The correlation calculation unit 211 performs correlation calculation processing on the received signal, whereby the GPS satellite signal is captured and output to the CPU 23. The navigation data of the captured GPS satellite signal is immediately demodulated by the CPU 23, and the orbit information and time information of the GPS satellite are extracted.

  Similarly, the pseudo satellite signal is captured by the correlation calculation unit 211 performing correlation calculation processing on the received signal, and the pseudo satellite signal is output to the CPU 23. The pseudo satellite data of the captured pseudo satellite signal is immediately demodulated by the CPU 23, and the arrangement position of the pseudo satellite, the control ID, and the like are taken out.

It is remembered. For example, for the call function, the current operation state is “◯ (can call)”, and the user setting is “impossible”. As for the incoming call mode, the current operation state is “manner mode”, and the user setting is “permitted”.

  The map data 809 is data in which map information in which names of regions, rivers, roads, facilities, buildings, and the like are associated with position information thereof is stored. In the present embodiment, the map data 809 is mainly used to identify the facility or place where the mobile phone 3 is currently located based on the latest output position.

  FIG. 9 is a diagram illustrating an example of data stored in the RAM 90. The RAM 90 stores a reception control ID 901, a latest control ID 903, a latest reception time 905, control history data 907, GPS satellite data 909, pseudo satellite data 911, and a latest output position 913.

  The reception control ID 901 is a control ID included in the currently received pseudo satellite signal. The latest control ID 903 is a control ID temporarily stored as the latest control ID. The latest reception time 905 is the time when the pseudo satellite signal was last received.

  FIG. 11 is a diagram illustrating an example of a data configuration of the control history data 907. In the control history data 907, the function 9071 of the mobile phone 3, the execution control content 9073 that is the control content executed for the function, and the control type 9075 of the function are stored in association with each other in the new order. .

  The execution control content 9073 stores the operation state of the function 9071 before execution of control and the operation state of the function 9071 after execution of control. The control type 9075 is “external instruction” when the execution control content 9073 is executed according to an external instruction based on a pseudo satellite signal, and the execution control content 9073 is executed according to an operation instruction by the user. If it is, the “user instruction” is stored.

  For example, from the data shown in FIG. 11, the call function is controlled to be “O (can call) → × (cannot call)” according to an external instruction based on the pseudo satellite signal, and the automatic answering function is simulated. It can be seen that control for changing from “OFF to ON” was executed in accordance with an external instruction based on the satellite signal. In addition, the incoming mode is changed from “normal mode to manner mode” in accordance with an external instruction based on a pseudo satellite signal, and the incoming volume is controlled to be reduced to “5 → 1” in accordance with a user instruction. Recognize.

  The GPS satellite data 909 is data extracted by demodulating the GPS satellite signal by the CPU 23 of the baseband processing circuit unit 20. The pseudo satellite data 911 is data extracted by demodulating the pseudo satellite signal by the CPU 23. The latest output position 913 is data of a position determined as the latest output position in the position calculation process.

4). Processing Flow FIG. 12 is a flowchart showing a main processing flow executed in the mobile phone 3 when the host CPU 30 reads and executes the main program 801 stored in the flash ROM 80.

  The main process is a process of starting execution when the host CPU 30 detects that a power-on operation has been performed by the user via the operation unit 40. Although not specifically described, during execution of the following main processing, reception of the RF signal by the GPS antenna 9 and down conversion from the RF signal to the IF signal by the RF reception circuit unit 11 are performed, and the IF signal is converted into a baseband processing circuit. It is assumed that the unit 20 is in a state of being output as needed. In addition, it is assumed that GPS satellite signals and pseudo satellite signals are captured by the baseband processing circuit unit 20 and data demodulated from these signals is output to the host CPU 30 as needed.

  First, the host CPU 30 starts a satellite signal reception process (step A1). Specifically, a process for causing the satellite capturing unit 21 of the baseband processing circuit unit 20 to try capturing the GPS satellite signal and a process for attempting to capture the pseudo satellite signal are repeatedly executed. That is, referring to the satellite type data 803 stored in the flash ROM 80, the received signal is changed while changing the replica code generated by the replica code generator 213 based on the PRN code assigned to the GPS satellite 5 and the pseudo satellite 7 respectively. The correlation calculation unit 211 executes the correlation calculation between the code and the replica code.

  Next, the host CPU 30 starts the external instruction operation control process by reading and executing the external instruction operation control program 8011 stored in the flash ROM 80 (step A3).

13 and 14 are flowcharts showing the flow of the external instruction operation control process.
First, the host CPU 30 determines whether or not a pseudo satellite signal has been received (step B1). If it is determined that it has been received (step B1; Yes), the control ID included in the pseudo satellite signal is received as a reception control ID 901. Is stored in the RAM 90 (step B3). Further, the host CPU 30 stores the time when the pseudo satellite signal is received in the RAM 90 as the latest reception time 905 (step B5).

  Next, the host CPU 30 determines whether or not the reception control ID 901 stored in the RAM 90 matches the latest control ID 903 (step B7). If it is determined that they match (step B7; Yes), the host CPU 30 determines whether or not external instruction operation control is being performed (step B9).

  If it is determined that the external instruction operation control is not being performed (step B9; No), the host CPU 30 determines whether or not the continuous reception time of the pseudo satellite signal has reached the first specified elapsed time ( Step B11) If it is determined that it has not yet reached (Step B11; No), the process returns to Step B1.

  When it is determined that the continuous reception time has reached the first specified elapsed time (step B11; Yes), the host CPU 30 determines whether or not the reception control ID 901 is “1” (step B13). ). If it is determined that the reception control ID 901 is “1” (step B13; Yes), the host CPU 30 refers to the control history data 907 in the RAM 90, and “external instruction” is stored in the control type 9075. The function 9071 is controlled to return to the operation state before execution of the execution control content 9073 (step B15).

  When it is determined that the reception control ID 901 is “1”, the power supply of the own device is turned off. When the power is turned on (ON) by a user operation after the power is turned off, it is assumed that the user's location has changed. Therefore, when the power is turned on, the process of step B15 is performed in order to return to the operation state set by the user instead of returning to the operation state changed by the external instruction based on the pseudo satellite signal.

  Then, the host CPU 30 clears the control history data 907 stored in the RAM 90 (step B17), and updates the function operation state data 807 of the flash ROM 80 based on the operation state of the function restored in step B15. (Step B19). Then, the host CPU 30 performs control to turn off the power of its own (step B21), and ends the main process.

  When it is determined in step B13 that the reception control ID 901 is not “1” (step B13; No), the host CPU 30 stores the operation state of the function to be controlled. That is, based on the operation state of the function to be controlled, the function operation state data 807 of the flash ROM 80 is updated (step B23), and the control history data 907 of the RAM 90 is updated (step B25).

  Then, the host CPU 30 refers to the external instruction operation control data 805 stored in the flash ROM 80 and controls to change the operation state of the target function 8053 according to the control content 8055 corresponding to the reception control ID 901 stored in the RAM 90. (Step B27). Then, the host CPU 30 returns to step B1.

  On the other hand, if it is determined in step B7 that the reception control ID 901 does not match the latest control ID 903 (step B7; No), the host CPU 30 updates the latest control ID 903 with the reception control ID 901 (step B29). Then, the continuous reception time of the pseudo satellite signal is reset (step B31), the measurement of the continuous reception time is restarted (step B33), and the process returns to step B1.

  If it is determined in step B9 that the external instruction operation control is being performed (step B9; Yes), the host CPU 30 determines whether an incoming call is received from another telephone (step B35), and If it is determined that there is an incoming call (step B35; Yes), it is determined whether or not the automatic answering function is “ON” with reference to the function operation state data 807 stored in the flash ROM 80 ( Step B37).

  If it is determined that the automatic answering function is “ON” (step B37; Yes), the host CPU 30 stores the latest output position 913 stored in the RAM 90 and the map data 809 of the flash ROM 80. The map information that has been checked is checked to identify the facility where the aircraft is currently located (step B39).

  Then, the host CPU 30 generates an answering machine response message in which the specified facility is reflected in the content (step B41). Specifically, if the name of the specified facility is “XX facility”, for example, “Because you are in the XX facility, you cannot answer the phone right now. Please give a message after the tone.” Generate answering machine response message with content.

  To create an answering machine response message, for example, text data of a fixed message other than a variable part message corresponding to “XX facility” is prepared, and the variable part message is combined with the fixed message to generate text data of the answering machine response message. After generating, the answering machine response message can be generated using a known technique for generating voice data from text data.

  Then, the host CPU 30 transmits the generated answering machine response message to the caller telephone set (step B43), and then returns to step B1. If it is determined in step B35 that there is no incoming call (step B35; No), or if it is determined in step B37 that the automatic answering function is not “ON” (step B37; No), the host CPU 30 Return to step B1.

  Returning to FIG. 13, when it is determined in step B1 that the pseudo satellite signal has not been received (step B1; No), the host CPU 30 determines whether or not external instruction operation control is being performed (step B45). If it is determined that the external instruction operation control is not being performed (step B45; No), the host CPU 30 returns to step B1.

  If it is determined that the external instruction operation control is being performed (step B45; Yes), the host CPU 30 refers to the latest reception time 905 stored in the RAM 90 and has received the pseudo satellite signal last time. Is determined (step B47). Then, the host CPU 30 determines whether or not the elapsed time has reached the second specified elapsed time (step B49).

  If it is determined that the elapsed time has reached the second specified elapsed time (step B49; Yes), the host CPU 30 refers to the control history data 907 in the RAM 90, and “external instruction” is stored in the control type 9075. The function 9071 is controlled to return to the operation state before execution of the execution control content 9073 (step B51).

  Then, the host CPU 30 clears the control history data 907 based on the operation state restored in step B51 (step B53) and updates the functional operation state data 807 stored in the flash ROM 80 (step B55). . Then, the host CPU 30 returns to step B1. If it is determined in step B49 that the elapsed time has not reached the second specified elapsed time (step B49; No), the host CPU 30 returns to step B1.

  Returning to the main process of FIG. 12, after starting the external instruction operation control process, the host CPU 30 starts the position calculation process by reading and executing the position calculation program 8013 stored in the flash ROM 80 (step S40). A5).

FIG. 15 is a flowchart showing the flow of the position calculation process.
First, the host CPU 30 determines whether or not a GPS satellite signal has been received from the GPS satellite 5 (step C1). If it is determined that the GPS satellite signal has been received (step C1; Yes), the host CPU 30 determines whether it has received the GPS satellite signal based on the GPS satellite signal. Is calculated (step C3).

  More specifically, the position is calculated by using the GPS satellite data 909 obtained by demodulating the GPS satellite signal to calculate the position. As the position calculation calculation, known methods such as position calculation calculation using the least square method and position calculation calculation using the Kalman filter can be applied. Then, the host CPU 30 updates the latest output position 913 of the RAM 90 with the calculated position (step C5), and returns to step C1.

  If it is determined in step C1 that no GPS satellite signal has been received (step C1; No), the host CPU 30 determines whether a pseudo satellite signal has been received from the pseudo satellite 7 (step C7). If it is determined that the pseudo satellite signal has been received (step C7; Yes), the host CPU 30 updates the latest output position 913 of the RAM 90 with the arrangement position of the pseudo satellite 7 included in the received pseudo satellite signal. (Step C9), the process returns to Step C1.

  If it is determined in step C7 that the pseudo satellite signal has not been received (step C7; No), the host CPU 30 returns to step C1.

  Returning to the main process of FIG. 12, after starting the position calculation process, the host CPU 30 determines an instruction operation performed by the user via the operation unit 40 (step A7), and the instruction operation is a call instruction operation. If it is determined (step A7; call instruction operation), call processing is performed (step A9). Specifically, the mobile phone radio communication circuit unit 60 performs base station communication with the radio base station, thereby realizing a call between the mobile phone 3 and another device.

  When it is determined in step A7 that the instruction operation is a mail transmission / reception instruction operation (step A7; mail transmission / reception instruction operation), the host CPU 30 performs a mail transmission / reception process (step A11). Specifically, base station communication is performed by the mobile phone wireless communication circuit unit 70 to realize transmission / reception of mail between the mobile phone 3 and another device.

  When it is determined in step A7 that the instruction operation is a function setting instruction operation (step A7; function setting instruction operation), the host CPU 30 performs a function setting process. Specifically, the control history data 907 in the RAM 90 is updated in accordance with the function operation state change request input by the user via the operation unit 40 (step A13), and the function operation state data 807 in the flash ROM 80 is updated. (Step A15).

  When it is determined in step A7 that the instruction operation is a position display instruction operation (step A7; position display instruction operation), the host CPU 30 performs a position display process (step A17). Specifically, a position display screen in which the latest output position 913 stored in the RAM 90 is plotted is generated using the map data 809 stored in the flash ROM 80 and displayed on the display unit 50.

  After performing the processing of steps A9 to A17, the host CPU 30 refers to the function operation state data 807 stored in the flash ROM 80, and controls the operation of the own device according to the currently set function (step A19).

  Thereafter, the host CPU 30 determines whether or not a power-off instruction operation has been performed by the user via the operation unit 40 (step A21). When it is determined that the user has not performed the operation (step A21; No), the host CPU 30 returns to step A7. If it is determined that the power-off instruction operation has been performed (step A21; Yes), the main process is terminated.

5). In the control system 1, the pseudo satellite 7 includes a control ID which is a kind of control code for controlling the mobile phone 3 in the pseudo satellite signal conforming to the signal standard of the GPS satellite signal from the GPS satellite 5. Outgoing. When the mobile phone 3 receives the pseudo satellite signal from the pseudo satellite 7, it measures the continuous reception time of the pseudo satellite signal. Then, whether or not the measured continuous reception time has reached the specified elapsed time is determined as a reception condition of the pseudo satellite signal, and when this reception condition is satisfied, the own device is based on the control ID included in the pseudo satellite signal. To control.

  In other words, unless the same pseudo satellite signal is continuously received, the mobile phone 3 is not controlled. Therefore, even if the cellular phone 3 accidentally receives a pseudo satellite signal, the cellular phone 3 is not controlled by itself, and the occurrence of erroneous control of the cellular phone 3 can be prevented. Further, even if a temporary reception error occurs, if the mobile phone 3 is controlled if continuous reception is performed, the certainty of the control of the mobile phone 3 can be improved.

  In addition, the pseudo-satellite 7 is designed in advance so that the signal reach of the pseudo-satellite signal is a specified distance (for example, a radius of 10 m centered on the position where the pseudo-satellite 7 is arranged). Since the signal reachable range has a spatial spread, it is spatially monitored whether or not the mobile phone 3 is located in the signal communication area, and the mobile phone 3 located in the signal communication area is The operation can be controlled uniformly.

  In the technique disclosed in Patent Document 1, the mobile communication terminal is controlled by determining whether or not the user has passed through the gate. That is, a “signal plane” perpendicular to the ground is formed by the mode switching signal transmitter and the antenna built in the pair of gates, and the position of the mobile communication terminal is monitored and controlled via the signal plane. . In this case, if the user passes the gate and the mobile communication terminal leaves the signal surface, the user can manually change the mode setting from the manner mode to the normal mode, so the switching control to the manner mode is possible. There is a problem that becomes meaningless. However, in this embodiment, as long as the mobile phone 3 is located in the signal communication area, even if the user manually returns the operation state of the mobile phone 3 to the state before the control, the mobile phone 3 Since the own apparatus is controlled again based on the received control ID, this problem can be solved.

  In addition, the technique disclosed in Patent Document 1 has a problem in that switching to the manner mode is not performed when the mobile communication terminal fails to receive the mode switching signal due to some problem when passing through the gate. . In this regard, in the present embodiment, the mobile phone 3 can be controlled in operation depending on whether or not the mobile phone 3 is located within the signal communication area, and therefore, not only when passing through the gate, but also within the signal communication area. If the mobile phone 3 is present, the operation control can be performed, and the reliability of the control can be improved.

  Furthermore, in the technique disclosed in Patent Document 1, since the mobile communication terminal is controlled by determining whether or not the user has passed through the gate, the mode switching of the mobile communication terminal is controlled in a certain space. Had a problem that it was necessary to install a transmitter at every gate where people entered and exited. In this regard, in the present embodiment, it is possible to spatially monitor whether or not the mobile phone 3 is located within the signal communication area, and to uniformly control the operation of the mobile phone 3 located within the signal communication area. Therefore, the mobile phone 3 can be controlled in operation by installing only one pseudo satellite 7 within the signal reach of the pseudo satellite 7. The configuration of this embodiment is particularly suitable for operation control in a space where an entrance / exit cannot be specified such as an outdoor concert venue.

  Various control contents of the mobile phone 3 are associated with the control ID. For example, the control for turning off the power of the mobile phone 3, the control for suppressing the call function, the control for suppressing mail transmission / reception, the control for turning on the automatic answering function, the control for setting the incoming mode to the manner mode, etc. ing. For this reason, by designing and arranging the pseudo satellite 7 so as to transmit a pseudo satellite signal including a control ID corresponding to the control content of the mobile phone 3 that is required, appropriate control according to the facility and place is performed. Can be realized.

  In the present embodiment, when the mobile phone 3 is controlled by the pseudo satellite signal, the operation state before the control and the operation state after the control are saved, and then the mobile phone 3 is controlled based on the control ID. Control the operation. Then, when the second specified elapsed time has elapsed since the last reception of the pseudo satellite signal, the operation state of the mobile phone 3 is restored to the stored operation state before the control. That is, when the continuous reception of the pseudo satellite signal is interrupted, it is possible to return to the operation state before the control, and it is possible to save the trouble of manually returning the operation state.

  Further, the mobile phone 3 checks the information on the arrangement position of the pseudo satellite 7 included in the pseudo satellite signal currently received by the GPS receiver 10 and the map information stored in advance, thereby checking the mobile phone 3. Specify the location (location name, facility, etc.) where is located. And the answering machine response message which reflected the name of the specified place in the content is generated. Then, after performing control to turn on the automatic answering machine function based on the control ID included in the pseudo satellite signal, when detecting that there is an incoming call from another telephone, the generated answering machine response message is sent to the sender Send to phone.

  Since the pseudo satellite signal transmitted from the pseudo satellite 7 includes information on the arrangement position of the pseudo satellite 7, the mobile phone 3 cannot receive the GPS satellite signal from the GPS satellite 5 and calculates the position. Even if it cannot be performed, the position of the own device can be estimated. In addition, since the answering machine response message including information on the arrangement position included in the currently received pseudo-satellite signal is to be transmitted to the caller telephone, the other party who called the mobile phone 3 It is convenient because it is possible to know where the user of the mobile phone 3 is located and why he / she cannot answer the phone.

6). Modification 6-1. Electronic Device The present invention can be applied to any electronic device as long as it is an electronic device provided with a position calculating device in addition to a mobile phone. For example, the present invention can be similarly applied to a notebook personal computer, a PDA (Personal Digital Assistant), a portable music playback device, a portable game device, and the like.

6-2. In the above-described embodiment, the GPS is described as an example of the satellite position calculation system, but WAAS (Wide Area Augmentation System), QZSS (Quasi Zenith Satellite System), GLONASS (GLObal NAvigation Satellite System), GALILEO Other satellite position calculation systems may be used.

6-3. Differentiation of Processing The CPU 23 of the baseband processing circuit unit 20 may perform part or all of the processing executed by the host CPU 30. For example, the CPU 23 performs position calculation processing and the host CPU 30 performs external instruction operation control processing. In this case, the CPU 23 outputs the latest output position obtained by the position calculation process to the host CPU 30. The host CPU 30 uses the latest output position input from the CPU 23 for various applications. Needless to say, the CPU 23 may execute the entire process including the external instruction operation control process.

6-4. In the above-described embodiment, when the pseudo satellite signal continuous reception time has reached the first specified elapsed time, the pseudo satellite signal reception condition is based on the control ID included in the pseudo satellite signal. The description has been made assuming that the mobile phone 3 is controlled. It is also possible to perform the same control based on the number of times that the mobile phone 3 continuously receives the pseudo satellite signal (hereinafter referred to as “the number of continuous receptions”). That is, a reception condition for the number of continuous receptions of the pseudo satellite signal is determined, and when the number of continuous receptions satisfies the reception condition, the mobile phone 3 is controlled according to the control ID included in the pseudo satellite signal. To do.

  Specifically, the mobile phone 3 measures and stores the number of times the same pseudo satellite signal is continuously received as the number of continuous receptions. Then, it is determined as a reception condition whether or not the measured number of continuous receptions has reached a predetermined specified number of receptions (for example, 5 times), and if it is determined that it has reached, the control ID included in the pseudo satellite signal is Based on this, the portable telephone 3 is controlled.

6-5. Similarly, the received signal strength is not based on the continuous reception time or the number of continuous receptions of the pseudo satellite signal, but based on the strength of the pseudo satellite signal received by the mobile phone 3 (hereinafter referred to as “received signal strength”). It is also possible to perform control. That is, a reception condition for the signal strength of the pseudo satellite signal is determined, and when the received signal strength satisfies the reception condition, the mobile phone 3 is controlled according to the control ID included in the pseudo satellite signal. .

  Specifically, the mobile phone 3 measures and stores the received signal strength of the pseudo satellite signal. Then, it is determined as a reception condition whether or not the received signal strength has reached a predetermined signal strength. When it is determined that the received signal strength has been reached, the mobile phone 3 is controlled based on the control ID included in the pseudo satellite signal. To do. When the received signal strength is too small, it is preferable to select and set an appropriate value as the threshold value of the received signal strength in order not to control the electronic device.

6-6. Combination of reception conditions Further, in the above-described control of the electronic device, the reception conditions for each of the continuous reception time, the number of continuous receptions, and the reception signal strength of the pseudo satellite signal are not individually determined, but the reception conditions are determined by combining them. It may be determined. That is, when any two or three of the continuous reception time, the number of continuous receptions, and the reception signal intensity satisfy the above-described reception conditions, the mobile phone 3 is controlled based on the control ID included in the pseudo satellite signal. You may do it.

  For example, when the continuous reception time reaches a predetermined specified reception time and the received signal strength reaches a predetermined signal strength, the mobile phone 3 is controlled based on the control ID included in the pseudo satellite signal. It is also possible. Similarly, control is similarly performed by a combination of conditions of continuous reception count and reception signal strength, a combination of continuous reception time and continuous reception count conditions, and a combination of continuous reception time, continuous reception count and reception signal strength conditions. Is also possible.

6-7. Setting of the prescribed elapsed time according to the control ID In the above-described embodiment, the first prescribed elapsed time and the second prescribed elapsed time have been described as being uniform. However, for example, different according to the control ID (control content) It is good also as setting time.

  FIG. 16 is a diagram showing an example of the data configuration of the second external instruction operation control data 825 stored in the flash ROM 80 in this case. In the second external instruction operation control data 825, a control ID 8251, a target function 8253, a control content 8255, a first specified elapsed time 8257, and a second specified elapsed time 8259 are stored in association with each other. ing.

  In the first specified elapsed time 8257 and the second specified elapsed time 8259, different times are set according to the control ID 8251. For example, for the control ID “2”, “20 seconds” is set as the first specified elapsed time, “5 seconds” is set as the second specified elapsed time, and for the control ID “4”, “10 seconds” is defined as the first specified elapsed time, and “15 seconds” is defined as the second specified elapsed time.

  In this case, the pseudo satellite 7 transmits the pseudo satellite signal including a plurality of control IDs, so that the mobile phone 3 located within the signal reachable range can be controlled step by step with a time difference. . For example, when the mobile phone 3 receives a pseudo satellite signal including three types of control IDs 8251 of “1”, “4”, and “7” in FIG. 16, five seconds have elapsed after the reception of the pseudo satellite signal is started. Later, the incoming mode is changed to the manner mode, the Internet connection is suppressed after 10 seconds, and the power is turned off after 30 seconds.

6-8. Assignment of a plurality of control contents Instead of assigning one kind of control contents to one control ID, a plurality of kinds of control contents may be assigned to one control ID.

  FIG. 17 is a diagram showing an example of the data configuration of the third external instruction operation control data 835 stored in the flash ROM 80 in this case. In the third external instruction operation control data 835, a plurality of combinations of the target function 8353, the control content 8355, the first specified elapsed time 8357, and the second specified elapsed time 8359 are associated with one control ID 8351. It is stored in association. In this case, the pseudo-satellite 7 transmits the pseudo-satellite signal including one type of control code, so that the mobile phone 3 located within the signal reachable range can be controlled step by step with a time difference. It becomes.

  For example, for the control ID “2”, the target function “call” and the control content “suppression”, the target function “auto answering machine”, and the control content “ON” are associated with each other. Both elapsed times are “20 seconds” and the second specified elapsed time is both “5 seconds”. Therefore, when the pseudo satellite signal including the control ID “2” is received, the mobile phone 3 controls to suppress the call function 20 seconds after starting the reception and to turn on the automatic answering function. .

  For example, for the control ID “3”, the target function “mail transmission / reception” and the control content “suppression”, the target function “Internet connection” and the control content “suppression”, and the target function “infrared communication” and control. The content “suppression” is associated. The first specified elapsed times are “15 seconds”, “10 seconds”, and “5 seconds”, respectively, and the second specified elapsed times are “10 seconds”, “15 seconds”, and “20 seconds”, respectively. is there. Therefore, when a pseudo satellite signal including the control ID “3” is received, the mobile phone 3 performs control so as to suppress infrared communication when 5 seconds have elapsed from the start of reception, and the Internet when 10 seconds have elapsed. Control is performed so as to suppress the connection, and when 15 seconds elapse, control is performed so as to suppress mail transmission / reception, and the communication function is suppressed in stages.

6-9. The control ID is assigned to the PRN code In the above-described embodiment, the control content of the mobile phone 3 is described as being associated with the control ID. However, the control ID (= control content) is associated with the PRN code. It is good also as composition which has.

  FIG. 18 is a diagram showing an example of the data configuration of the fourth external instruction operation control data 845 stored in the flash ROM 80 in this case. In the fourth external instruction operation control data 845, a PRN code 8451, a target function 8453, and a control content 8455 are stored in association with each other.

  For example, for the PRN code “173”, the target function “power supply” and the control content “disconnect” are stored in association with each other. That is, this is equivalent to the control ID “1” of the above-described embodiment being assigned to the PRN code “173”. Further, for the PRN codes “174” and “175”, the target function “call” and the control content “suppression” are stored in association with each other. That is, it is equivalent to the control ID “2” of the above-described embodiment being assigned to the PRN codes “174” and “175”.

  In this case, for example, by installing a pseudo-satellite with a PRN code “173” in the vicinity of the priority seat of the train, the power of the mobile phone 3 located in the vicinity of the priority seat can be forcibly cut off. It becomes possible. In addition, for example, by installing a pseudo-satellite with PRN codes “174” and “175” in a place other than the priority seat of the train, calls of the mobile phone 3 located in a place other than the priority seat are forcibly suppressed. can do. According to such a configuration, the PRN code and the location of the pseudo satellite 7 can be associated with each other, so that maintenance management of the pseudo satellite 7 is facilitated.

  Of course, it is not necessary to assign one type of control content to one PRN code, and it is needless to say that a plurality of types of control content may be assigned to one PRN code.

6-10. In the above-described embodiment, when the second specified elapsed time has elapsed since the last pseudo satellite signal was received, all the operation states other than the operation state controlled according to the user instruction are displayed as the operation states before the control. It was explained as something to be restored. Rather than adopting such a configuration, for each pseudo satellite signal, the elapsed time from the last reception of the pseudo satellite signal is measured, and when the second specified elapsed time has elapsed, the pseudo satellite The operation state controlled based on the control ID included in the signal may be returned to the operation state before the control.

  For example, in the example of the live facility shown in FIG. 1, when the user carrying the mobile phone 3 enters the entrance hall from the lobby, the last pseudo satellite signal is received from the pseudo satellite 7b arranged in the lobby. When the second specified elapsed time has elapsed, the mobile phone 3 returns the incoming mode from the manner mode to the normal mode. When the second specified elapsed time has elapsed since the user entered the outdoor hall from the entrance hall and received the pseudo satellite signal last from the pseudo satellite 7a arranged in the entrance hall, the mobile phone 3 Control to return to the original. As a result, the operation state of the mobile phone 3 can be restored in stages.

6-11. Providing a Service According to the Position of the Pseudo Satellite It is possible to provide the mobile phone 3 with a service according to the position of the pseudo satellite included in the pseudo satellite signal. For example, a server (hereinafter referred to as “service providing server”) for providing a service on the service provider side is prepared. The service providing server has a database storing services and contents corresponding to facilities and places.

  The mobile phone 3 that has received the pseudo-satellite signal from the pseudo-satellite accesses the service providing server and transmits information on the arrangement position included in the pseudo-satellite signal to the service providing server. When the service providing server receives the location information from the mobile phone 3, the service providing server checks the location information and the map information to identify the facility or place where the mobile phone 3 is located. Then, a service corresponding to the specified facility is read from the database and provided to the mobile phone 3.

  Thereby, for example, when the mobile phone 3 is located at a live facility, the mobile facility 3 can be provided with a guide map of the live facility and information regarding live performance. Further, when the mobile phone 3 is located in a movie theater or a museum, it is possible to provide the mobile phone 3 with information about movies and information about paintings and sculptures.
