For example, the power supply unit 205 includes a plug inserted into a power outlet or a dry battery. The coil 206 is for transmitting electric power to the mobile communication terminal 10 by an electromagnetic induction method. Further, the charger 20 can be positioned and placed so that the mobile communication terminal 10 can be charged (so that the coils 109 and 206 can be charged with each other) in the same manner as a conventional charger. Equipped with a table. The hardware itself can be the same as that of a conventional charger. By operating these components, each function of the charger 20 described later is exhibited.

  Subsequently, functions of the mobile communication terminal 10 and the charger 20 according to the present invention will be described. As shown in FIG. 1, the mobile communication terminal 10 includes a mobile communication unit 11, a battery 108, a charging unit 12, a power off unit 13, and a power on unit 14.

  The mobile communication unit 11 is a mobile communication unit that executes a mobile communication function. Specifically, the mobile communication unit 11 performs wireless communication with a base station or the like according to a user operation, and transmits and receives voice data and packet data. The mobile communication unit 11 operates when the power supplied from the battery 108 is supplied.

  In addition, the mobile communication terminal 10 is turned on and off, and power is supplied to the mobile communication unit 11 only when the power is on. When the power is off, supply of power to the mobile communication unit 11 is prohibited. The power is turned on / off by a user's operation such as pressing a power button provided in the mobile communication terminal 10 or by a power off unit 13 and a power on unit 14 according to the function of the present invention as will be described later.

  The battery 108 is a battery that supplies electricity for the mobile communication unit 11 to function. The battery 108 is consumed when the mobile communication unit 11 operates. Further, as described above, the battery 108 is charged from the charger 20 when the mobile communication terminal 10 is connected to the charger 20.

  The charging unit 12 is a charging unit that is connected to the charger 20 so that the battery 108 can be charged and charges the battery from the charger 20. The charging unit 12 includes a charging coil 109 and is connected to the charger 20 in a non-contact manner to charge the battery 108. Specifically, the charging unit 12 takes out a charging current from the change in the magnetic field from the charger 20 side by the coil 109. The connection with the charger 20 means that charging power can be transmitted to and received from the charger 20.

  In addition, the charging unit 12 performs transmission / reception of power used to input power to the battery 108 and information used for authentication and power control on the charger 20 side with the charger 20. These pieces of information are modulated as necessary. Further, the charging unit 12 can detect the connection with the charger 20 by detecting the coil 206 of the charger 20. Specifically, the detection of the coil is performed by resonance at a specified frequency using a resonance circuit provided in the mobile communication terminal 10. These functions are the same functions as the functions related to charging of the conventional mobile communication terminal.

  In addition, the charging unit 12 outputs information to the power-off unit 13 and the power-on unit 14 as necessary.

  The power-off unit 13 is power-off means for detecting the connection with the charger 20 by the charging unit 12 or the charging by the charging unit 12 and powering off the terminal 10 itself. Specifically, the power-off unit 13 monitors the charging unit 12 and turns off the power when the charging unit 12 starts charging the battery 108. Alternatively, the power may be turned off when the charging unit 12 is connected to the charger 20 and the battery 108 can be charged. When the power is turned off, the supply of power to the mobile communication unit 11 is prohibited as in the case where the power is turned off by a user operation.

  Further, the power-off unit 13 acquires first type information indicating the type of the charger 20 from the charger 20 connected by the charging unit 12, and sets the own terminal 10 according to the first type information. It is good also as a structure which powers off. That is, the power-off unit 13 may selectively turn off the own terminal 10 according to the charger 20. Here, the first type information is, for example, information indicating that the charger 20 powers off the mobile communication terminal 10 at the time of charging, and the charger 20 that does not power off the mobile communication terminal 10 at the time of charging. And two types of information. Any of these pieces of information is set in the charger 20 as the first type information, and is transmitted from the charger 20 to the mobile communication terminal 10 at a predetermined timing such as when charging is started. In the mobile communication terminal 10, the power-off unit 13 receives the first type information via the charging unit 12.

  If the received first received information is information indicating that the mobile communication terminal 10 is powered off at the time of charging, the power off unit 13 performs a process of powering off the terminal 10 itself. When the received first received information is information indicating that the charger 20 does not power off the mobile communication terminal 10 during charging, the power off unit 13 does not perform the process of powering off the terminal 10 ( No special processing).

  The charger 20 set to information indicating that the first type information is a charger 20 that turns off the mobile communication terminal 10 during charging is provided outside the communication area (out of service area) of the mobile communication terminal 10. It is desirable that the charger 20 be used. In addition, it is desirable to make the above setting also in a place where it is desirable to turn off the power, for example, a movie theater or a concert venue.

  Further, the first type information may be information for identifying each charger 20 (for example, an ID of the charger 20 or the like). In that case, the power-off unit 13 stores in advance information as to whether or not the mobile communication terminal 10 is to be powered off at the time of charging for each piece of information specifying each charger 20, and based on the information, the own terminal 10 It is also possible to determine whether or not to power off. That is, when the power-off unit 13 stores the information that the mobile communication terminal 10 is turned off at the time of charging corresponding to the received first reception information, the power-off unit 13 performs a process of turning off the own terminal 10. Do. In response to the received first received information, the power-off unit 13 stores information that does not power off the mobile communication terminal 10 at the time of charging, and does not perform a process of powering off the terminal 10 ( No special processing).

  The power-on unit 14 is power-on means for powering on the terminal 10 at a predetermined timing after the power-off unit 13 is powered off. The power-on unit 14 is an optional component that is not necessarily provided in the mobile communication terminal 10. In addition, when the power-off unit 13 is turned off by the power-off unit 13, the power-off unit 13 is notified of the fact. In addition, since the power-on unit 14 functions in a state where the own terminal 10 is powered off, it is desirable to operate the auxiliary battery provided in the mobile communication terminal 10 other than the battery 108, for example.

  The power-on unit 14 detects that the connection with the charger 20 by the charging unit 12 is disconnected after the power-off unit 13 is turned off, and turns on the terminal 10 itself. Specifically, the power-on unit 14 monitors the detection state of the coil 206 of the charger 20 by the charging unit 12 and turns on the terminal 10 at a timing when the coil 206 of the charger 20 is no longer detected. .

  The power-on unit 14 may turn on the terminal 10 after a set time after the power-off unit 13 turns off the power. The set time is set in advance by the user or the like and stored in the power-on unit 14. Specifically, the power-on unit 14 starts timing by a timer when the power-off unit 13 powers off the terminal 10 and turns on the power when the timer expires (when the set time has elapsed).

  Further, the power-on unit 14 confirms that the charging unit 12 is not connected to the charger 20 when the timer expires, that is, the coil 206 of the charger 20 is not detected by the charging unit 12. It may be turned on. That is, the power is turned on only when the coil 206 is not detected when the timer expires. If the coil 206 is detected when the timer expires, the power-on unit 14 starts counting by the timer again, and turns on the power when the timer expires again.

  Further, the power-on unit 14 acquires second type information indicating the type of the charger 20 from the charger 20 connected by the charging unit 12, and sets the own terminal 10 according to the second type information. A configuration may be adopted in which the power is turned on. That is, the power-on unit 14 may selectively power on the terminal 10 according to the charger 20. Here, the second type information includes, for example, information indicating that the charger 20 powers on the mobile communication terminal 10 and information indicating that the charger 20 does not power on the mobile communication terminal 10. There are two types of information. Any of these pieces of information is set in the charger 20 as the second type information, and is transmitted from the charger 20 to the mobile communication terminal 10 at a predetermined timing such as when charging is started. In the mobile communication terminal 10, the power-on unit 14 receives the second type information via the charging unit 12.

  When the received second received information is information indicating that the charger 20 powers on the mobile communication terminal 10, the power-on unit 14 performs the process of powering on the terminal 10 as described above. . When the received second received information is information indicating that the charger 20 does not power on the mobile communication terminal 10, the power on unit 14 does not perform a process of powering on the terminal 10 (particularly No processing).

  When the second type information is set to information indicating that the charger 20 powers on the mobile communication terminal 10, the charger 20 uses the mobile communication terminal immediately after being removed from the charger 20. It is desirable to use the charger 20 provided in a place where the operation is performed. In addition, for example, it is desirable to set the above setting even in a movie theater or concert venue where the power is forcibly turned off by the function of the present invention. On the other hand, when the second type information is set to information indicating that the charger 20 does not turn on the mobile communication terminal 10, the user immediately moves when the charger 20 is removed from the charger 20. It is desirable to use the charger 20 provided in a place where the communication terminal is not used.

  Further, the second type information may be information for identifying each charger 20 (for example, an ID of the charger 20 or the like). In that case, the power-on unit 14 stores in advance information on whether or not to power on the mobile communication terminal 10 for each piece of information specifying each charger 20, and powers the terminal 10 based on the information. It may be determined whether or not to turn on. That is, the power-on unit 14 performs a process of powering on its own terminal 10 when information indicating that the mobile communication terminal 10 is powered on is stored corresponding to the received second received information. In response to the received second received information, the power-on unit 14 stores information that does not power-on the mobile communication terminal 10, and does not perform a process of powering on the terminal 10 itself (specially No processing). The above is the function of the mobile communication terminal 10 according to the present invention.

  As shown in FIG. 1, the charger 20 includes a charger side charging unit 21 and a transmission unit 22.

  The charger side charging unit 21 is a charging unit on the charger side that is connected to the mobile communication terminal 10 and transmits power for charging the battery included in the mobile communication terminal 10 to the mobile communication terminal 10. Specifically, the charger-side charging unit 21 causes an induced current to occur in the coil 109 on the mobile communication terminal 10 side by causing an alternating current to flow through the coil 206 with the power supplied from the power supply unit 205. Further, the charger side charging unit 21 aligns the coil 109 of the mobile communication terminal 10 and the coil 206 of the charger 20 so that charging is appropriately performed before charging. The alignment is performed by, for example, physically moving the coil 206 or selecting a rechargeable coil 206 from among the plurality of coils 206. The coil alignment is performed in the same manner as a conventional charging system. Further, the positioning of the coil may be performed on the mobile communication terminal 10 side.

  In addition, the charger side charging unit 21 transmits / receives information used for authentication and power control on the charger 20 side to / from the connected mobile communication terminal 10. Further, the charger-side charging unit 21 performs demodulation of information received from the mobile communication terminal 10, authentication of the mobile communication terminal 10 using the information, control of current flowing through the coil 206, modulation, and the like. These functions are the same functions as the functions related to the charging of the conventional charger.

  The transmission unit 22 is means for transmitting information used for the function according to the present invention to the connected mobile communication terminal 10 via the charger side charging unit 21. Specifically, the transmission unit 22 is a first type information transmission unit that transmits first type information related to the charger 20 itself to the connected mobile communication terminal 10. Alternatively, the transmission unit 22 is a second type information transmission unit that transmits the second type information related to the charger 20 itself to the connected mobile communication terminal 10. The first type information and the second type information to be transmitted are set in advance by the administrator of the charger 20 and stored in the transmission unit 22. This setting may be performed by a mechanical switch provided in the charger 20, or may be performed by software. By making the type information settable in this way, a single charger 20 can perform a plurality of operations on the mobile communication terminal 10 side. The above is the function of the charger 20 according to the present invention.

  Subsequently, processing executed in the charging system 1 according to the present embodiment will be described with reference to the flowcharts of FIGS. In this description, the case where the mobile communication terminal 10 is powered off and the case where the power is turned on will be described separately. Moreover, it demonstrates for every function of the charging system 1 in each case. First, the case where the power is turned off will be described with reference to the flowchart of FIG. In this process, the mobile communication terminal 10 is started in a power-on state.

  First, the mobile communication terminal 10 is placed on a stand for the charger 20 (S10). This is performed in order to charge the battery 108 by the user of the mobile communication terminal 10. When the mobile communication terminal 10 is placed on the stand of the charger 20, in the charger 20, the coil 109 of the mobile communication terminal 10 is detected by the charger side charging unit 21 (S11). Subsequently, alignment of the coil 109 of the mobile communication terminal 10 and the coil 206 of the charger 20 is performed (S12).

  Subsequently, in the mobile communication terminal 10, authentication information for starting charging is generated by the charging unit 12 and transmitted to the charger 20 (S13). In the charger 20, the transmitted information is received by the charger-side charging unit 21, and authentication is performed based on the received information (S14). When it is determined that the mobile communication terminal 10 can be charged by the authentication, charging is started (S15). Specifically, an alternating current for charging is passed through the coil 206 of the charger 20.

  In the mobile communication terminal 10, the charging unit 12 extracts the charging current from the magnetic field change from the charger 20 side and charges the battery 108. When charging of the battery 108 is started, charging is detected by the power-off unit 13 (S16). When charging is detected, the mobile communication terminal 10 is powered off by the power off unit 13 (S17). In the mobile communication terminal 10, when the power is turned off, the power supply to the mobile communication unit 11 is prohibited, the mobile communication function is stopped, and the cell search is not performed. The above is the processing when the power is turned off.

  In the processing described with reference to FIG. 4, the mobile communication terminal 10 uniformly turns off the power when charging is detected. Subsequently, a mode in which the power is selectively turned off according to the first type information set in the charger 20 will be described with reference to the flowchart of FIG. In this process, the mobile communication terminal 10 is started in a power-on state.

  First, similarly to S10, the mobile communication terminal 10 is placed on a stand for the charger 20 (S20). When the mobile communication terminal 10 is placed on the cradle of the charger 20, in the charger 20, the coil 109 of the mobile communication terminal 10 is detected by the charger side charging unit 21 (S21). Subsequently, as in S12, alignment of the coil 109 of the mobile communication terminal 10 and the coil 206 of the charger 20 is performed (S22).

  Subsequently, similarly to S23, in the mobile communication terminal 10, the charging unit 12 generates authentication information for starting charging and transmits it to the charger 20 (S23). In the charger 20, as with S24, the transmitted information is received by the charger-side charging unit 21, and authentication is performed based on the received information (S24).

  Subsequently, in the charger 20, the first type information is transmitted to the mobile communication terminal 10 by the transmitter 22 via the charger-side charger 21 (S25). In the mobile communication terminal 10, the first type information transmitted from the charger 20 is received and stored by the power-off unit 13 via the charging unit 12 (S26). If it is determined by the authentication in S24 that the mobile communication terminal 10 can be charged, charging is started in the same manner as in S15 (S27).

  In the mobile communication terminal 10, the charging unit 12 extracts the charging current from the magnetic field change from the charger 20 side and charges the battery 108. When charging of the battery 108 is started, charging is detected by the power-off unit 13 (S28). When the charging is detected, the power-off unit 13 determines whether the first reception information received in S26 is information indicating that the charger 20 turns off the mobile communication terminal 10 during charging. (S29).

  If it is determined that the first received information is information indicating that the charger 20 turns off the mobile communication terminal 10 during charging, the power supply off unit 13 turns off the mobile communication terminal 10 (S30). . The first reception information is not information indicating that the charger 20 powers off the mobile communication terminal 10 during charging (the first reception information indicates that the charger 20 does not power off the mobile communication terminal 10 during charging. If it is determined that the power is off, the power is not turned off. This is a process in which the power is selectively turned off.

  Subsequently, a process of turning on the mobile communication terminal 10 after the mobile communication terminal 10 is turned off according to the flow shown in FIG. 4 or 5 will be described with reference to the flowcharts of FIGS. First, an aspect in which the power is turned on with the mobile communication terminal 10 taken out from the charger 20 as a trigger will be described with reference to FIG. In this process, the mobile communication terminal 10 is placed on the cradle of the charger 20 according to the flow shown in FIG. 4 or FIG.

  First, the mobile communication terminal 10 is taken out from the stand of the charger 20 (S40). This is performed in order to carry the mobile communication terminal 10 by the user of the mobile communication terminal 10.

  When the mobile communication terminal 10 is taken out of the stand of the charger 20, the mobile communication terminal 10 and the charger 20 are physically separated from each other, and the charging unit 12 and the charger 20 of the mobile communication terminal 10 are separated from each other. The connection is broken. That is, the detection state of the coil 206 of the charger 20 by the charging unit 12 becomes a non-detection state. In the mobile communication terminal 10, the non-detection of the coil 206 of the charger 20 is detected by the power-on unit 14 (S41). As described above, when the coil 206 of the charger 20 is not detected, the terminal 10 is powered on by the power-on unit 14 (S42). The above is the process in which the power is turned on with the mobile communication terminal 10 taken out from the charger 20 as a trigger.

  Subsequently, referring to FIG. 7, a mode in which the power is turned on with a set time elapses after the mobile communication terminal 10 is turned off by the function of the present invention will be described.

  In this process, first, the mobile communication terminal 10 is placed on the cradle of the charger 20 according to the flow shown in FIG. 4 or 5 from the power-on state, and the power is turned off (S50). Thereafter, the battery 108 of the mobile communication terminal 10 is charged (not shown) between the charger 20 and the mobile communication terminal 10 as in the flow shown in FIG. 4 or FIG. In the mobile communication terminal 10, when the power is turned off, the power-on unit 14 starts measuring time by a timer (S51). When the set time elapses, the timer expires (S52). In addition, when the power of the mobile communication terminal 10 is turned on other than the functions according to the present invention such as a user operation before the timer expires, the power-on function by the power-on unit 14 is stopped.

  When the timer expires, the power-on unit 14 confirms the connection between the charging unit 12 and the charger 20 (S53). That is, it is confirmed by the charging unit 12 whether or not the coil 206 of the charger 20 is detected.

  Here, if the mobile communication terminal 10 has not been taken out of the charger 20 stand before the timer expires, the mobile communication terminal 10 remains on the charger 20 stand. In this case, therefore, the coil 206 of the charger 20 is detected by the charging unit 12. When the coil 206 is detected (YES in S54), the power-on unit 14 resets the timer (S55). Subsequently, the timer is again started by the power-on unit 14, and the subsequent processing is repeated (S51 to S54).

  If the mobile communication terminal 10 has been removed from the stand of the charger 20 by the expiration of the timer of S51 to S52, the mobile communication terminal 10 and the charger 20 are physically separated. In this case, at the time of S53, the connection between the charging unit 12 of the mobile communication terminal 10 and the charger 20 is disconnected, and the coil 206 of the charger 20 is not detected by the charging unit 12. When the coil 206 is not detected (NO in S54), the power supply unit 14 turns on the power of the terminal 10 (S56).

  In the above-described process, the detection of the coil 206 is confirmed in S53, and the mobile communication terminal 10 is turned on according to the result of the confirmation. However, the detection of the coil 206 is not confirmed in S53. The power may be turned on uniformly when the set time has elapsed. The above is the process in which the power is turned on with the set time elapses as a trigger.

  Subsequently, using the flowchart of FIG. 8, after the mobile communication terminal 10 is powered off by the function of the present invention, the power is selectively turned on according to the second type information set in the charger 20. Will be described.

  In this process, first, the mobile communication terminal 10 is placed on the cradle of the charger 20 according to the flow shown in FIG. 4 or 5 from the power-on state, and the power is turned off (S61). During the power-off process, in the charger 20, the second type information is transmitted to the mobile communication terminal 10 by the transmitter 22 via the charger-side charger 21. In the mobile communication terminal 10, the second type information transmitted from the charger 20 is received and stored by the power-on unit 14 via the charging unit 12 (S60). The transmission / reception timing of the second type information can be the same as the transmission / reception timing of the first type information shown in FIG. 5, for example.

  After the mobile communication terminal 10 is turned off, the battery 108 of the mobile communication terminal 10 is charged between the charger 20 and the mobile communication terminal 10 as in the flow shown in FIG. 4 or FIG. (Not shown). Thereafter, the mobile communication terminal 10 is taken out from the stand of the charger 20 in the same manner as S40 in the flowchart shown in FIG. 6 (S62).

  When the mobile communication terminal 10 is taken out of the stand of the charger 20, the mobile communication terminal 10 and the charger 20 are physically separated from each other, and the charging unit 12 and the charger 20 of the mobile communication terminal 10 are separated from each other. The connection is broken. That is, the detection state of the coil 206 of the charger 20 by the charging unit 12 becomes a non-detection state. In the mobile communication terminal 10, the non-detection of the coil 206 of the charger 20 is detected by the power-on unit 14 (S63).

  If the coil 206 is not detected in the mobile communication terminal 10, then, whether or not the second reception information received in S 60 is information indicating that the charger 20 powers on the mobile communication terminal 10. Is determined by the power-on unit 14 (S64).

  If it is determined that the second received information is information indicating that the charger 20 powers on the mobile communication terminal 10, the mobile communication terminal 10 is powered on by the power-on unit 14 (S65). . The second reception information is not information indicating that the charger 20 powers on the mobile communication terminal 10 (the first reception information is information indicating that the charger 20 does not power on the mobile communication terminal 10). ), The power is not turned on. The above is the process of the aspect which selectively turns on a power supply according to the 2nd type information set to the charger 20. FIG.

  Note that the process of selectively turning on the power according to the above-described second type information is turned on with the mobile communication terminal 10 taken out from the charger 20 as a trigger as shown in the flowchart of FIG. Based on embodiment. However, as shown in the flowchart of FIG. 7, the power may be turned on when a set time has elapsed.

  In the above-described process, whether to turn on the power based on the second reception information is determined at the timing of turning off the power. However, it is not necessarily performed at this timing. For example, it may be performed at the timing before the terminal 10 is powered off, such as the timing at which the second type information is received.

  As described above, in the present embodiment, the mobile communication terminal 10 is automatically turned off when the mobile communication terminal 10 can be charged from the charger 20 or is actually charged. can do. Therefore, even when the mobile communication terminal 10 is out of service, the battery 108 is not consumed by cell search or the like. Thereby, according to this embodiment, even if the mobile communication terminal 10 is connected to the charger 20, consumption and charge of the battery 108 are not repeated, and deterioration of the battery can be prevented.

  Further, as described in the above-described embodiment, the mobile communication terminal 10 may be selectively turned off based on the first type information set in the charger 20. According to this configuration, the mobile communication terminal 10 is connected to the charger 20 provided in a place where the mobile communication terminal 10 is out of service area, or in a place where the mobile communication terminal such as a movie theater or a concert venue should be powered off. Only when the mobile communication terminal 10 can be automatically turned off. Thereby, a user's convenience can be improved. However, the selective power-off is not necessarily performed, and the power-off may be performed uniformly for any charger 20.

  Further, as described in the above-described embodiment, it is desirable to power on the mobile communication terminal 10 when the connection with the charger 20 is disconnected after the power is automatically turned off. According to this configuration, the mobile communication terminal 10 can be automatically turned on when there is no risk of battery deterioration due to repeated consumption and charging of the battery 108. Thereby, it is not necessary for the user to turn on the power manually, and the convenience for the user can be improved. For example, it is not necessary to manually turn on the mobile communication terminal 10 after leaving a movie theater or a concert venue. It is not always necessary to turn on the power.

  Alternatively, as described in the above-described embodiment, after the power is automatically turned off, the mobile communication terminal 10 may be turned on after a set time. This configuration also eliminates the need for the user to manually turn on the power, improving user convenience.

  Further, as described in the above-described embodiment, the mobile communication terminal 10 may be selectively turned on based on the second type information set in the charger 20. According to this configuration, when charging is performed using the charger 20 that is often not used by the user after charging, the mobile communication terminal 10 can be kept powered off. Therefore, it is possible to prevent consumption of the battery 108 due to the power being turned on when the user does not use the mobile communication terminal 10. However, it is not always necessary to selectively turn on the power, and any charger 20 may be turned on uniformly.

  In the above-described embodiment, the charger 20 is configured to perform information processing, but the charger may not necessarily be configured to perform information processing. That is, the mobile communication terminal 10 may be mechanically charged.

  Further, in the present embodiment, the battery 108 is charged by a non-contact method, but the non-contact method is not necessarily required. For example, the present invention may be applied to a method in which the mobile communication terminal 10 and the charger 20 are connected through a cable or a contact to perform charging.
