Description

  The present invention is used for a wireless communication terminal device such as a mobile phone terminal having a built-in function for performing contactless communication between a predetermined terminal and an IC card. In particular, the present invention relates to low voltage alarm control and automatic power shutoff control techniques for avoiding battery deterioration.

  In addition, in this specification, in order to make the explanation easy to understand, the description is mainly given as an invention applied to a ticket sales service when entering and exiting a railway ticket gate. The ticket ticket sales service can be replaced with an entrance ticket sales service or an attendee recognition service.

  Currently, contactless IC cards are used as information communication means such as payment of charges for NTT public telephones, payment of various railway organizations such as JR, and payment of electronic money at convenience stores. The non-contact IC card is a mechanism for supplying power to the internal IC by exchanging information with the other party by generating self-electromotive force in the card during data communication with the opposite communication device (reader / writer). Therefore, the user can use it with the same consciousness as a general contact card without being conscious of battery exhaustion due to current consumption during communication.

  However, with respect to the non-contact IC card function implemented as one function of a recent cellular phone or the like, since the power source for the non-contact IC card function is also supplied from the power battery built in for the telephone communication means, If the remaining battery level is low, the contactless IC card function cannot be used.

  In general, the non-contact IC card function built into a mobile phone stops functioning as a mobile phone because the minimum operating voltage value of the non-contact IC card function is lower than the minimum operating voltage value of the mobile phone. Only the non-contact IC card function can be operated even during the operation (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2001-223631

  As described above, the non-contact IC card function built in a wireless communication terminal device such as a mobile phone terminal reduces the battery voltage value of the wireless communication terminal device, Even after the mail transmission / reception function or the camera function is stopped, only the non-contact IC card function can be operated.

  However, conventionally, when the original function of the wireless communication terminal device is stopped, all the display functions are also stopped at the same time, so that the user recognizes that only the non-contact IC card function is still operating normally. There is no means to do it.

  Therefore, the user has to consider that the non-contact IC card function is also stopped when the original function of the wireless communication terminal device is stopped, and even if the non-contact IC card function can be used with much effort. It was a situation that I had to lose weight to use this.

  The present invention has been made under such a background, and a non-contact IC card function built in a wireless communication terminal device such as a mobile phone is used for a ticket sales service when entering a railway ticket gate. When used and have not yet entered the ticket gate, the probability that the wireless communication terminal will stop functioning due to a decrease in battery voltage is reduced compared to other situations, or the railway ticket gate The contactless IC card function built into the wireless communication terminal device such as a mobile phone is used for the ticket sales service at the time of admission, and the contactless IC card function is available in situations where the ticket gate has not yet been entered. The display of the operational availability state can be displayed separately from the display of the operational availability state of the original function of the wireless communication terminal device, for example, even after the original function of the wireless communication terminal device is stopped. And to provide a wireless communication terminal with the contactless IC card function.

  The present invention has a built-in non-contact IC card function that can communicate with a second party while the user is moving, such as a mobile phone terminal or a PHS terminal, and can be used as electronic money. When using a non-contact IC card function at the entrance of various railway institutions, etc., the existing wireless communication terminal switches from the conventional battery table to the entry battery table, and a low voltage alarm is activated. It is characterized in that the operating state of the non-contact IC to the user is visualized by lowering the emission voltage value.

  That is, the present invention is a wireless communication terminal device incorporating a non-contact IC card function for communicating with a predetermined terminal, and a feature of the present invention is that the battery voltage value is triggered by communication with the predetermined terminal. A means for changing the battery table including a record of the correspondence with the low voltage alarm issuing timing is provided.

  For example, the predetermined terminal is a facility entrance terminal, and the means for changing is an entrance battery whose alarm output voltage value is set lower than before the facility entrance triggered by communication with the predetermined terminal. A means for changing to a table is provided.

  Thus, for example, in a situation where the ticket sales service when entering the ticket gate uses the contactless IC card function built in the wireless communication terminal device and the ticket gate is not yet entered, Compared with the bottom, it is possible to reduce the probability that the wireless communication terminal device will stop functioning due to a decrease in the battery voltage value.

  In addition, for example, the predetermined terminal is a facility entry terminal, and the changing means returns the entrance battery table to the normal battery table before entering the facility, triggered by communication with the predetermined terminal. Means.

  As a result, for example, after entering the ticket gate, low voltage alarm control and automatic power cut-off control can be performed as usual using the normal battery table.

  Further, when the predetermined terminal is a facility entry terminal and the battery voltage value after entering the facility is a low voltage value corresponding to turning off the power in view of the normal battery table, the operation is performed after entering the facility. It is possible to provide means for turning off the power after waiting for completion of the predetermined processing.

  Thereby, for example, the probability that the non-contact IC card function stops before the settlement process can be reduced. In addition, since it can be determined by referring to the settlement record recorded on the IC card whether the settlement process is necessary after entering the ticket gate, the necessity of the settlement process is determined based on the settlement record. By providing means for determining the above, the above-described invention can be realized. Alternatively, the present invention can also be realized by simply delaying power OFF for a predetermined time (for example, 5 minutes) after entering the ticket gate.

  Moreover, a means to notify a user of the switching condition of the said battery table can be provided. Thereby, the user can take measures such as refraining from using the telephone function, the mail transmission / reception function, the camera function, and the like, which are the original functions of the wireless communication terminal device.

  The battery table can be switched according to an operation input. According to this, it is possible to prohibit the battery table switching execution according to the user's wishes.

  In addition, it is possible to provide means for restricting terminal functions other than the non-contact IC card function in a stepwise manner in accordance with the state of decrease in the power supply voltage value after switching to the battery table for entrance. According to this, it is possible to automatically perform power saving control, for example, to stop the function in order from the function with the largest power consumption, and to avoid the situation where even the non-contact IC card function stops. it can.

  Further, it is possible to provide means for setting a restriction target function or restriction order of the means for restricting according to an operation input. According to this, according to a user's hope, the function to stop and its order can be set up.

  The notification means may include a plurality of notification forms, and a means for selecting one of a plurality of notification forms according to a state of a decrease in the battery voltage value after switching to the entrance battery table. .

  For example, when the battery voltage value is relatively high, normal display is performed. When the battery voltage value is relatively low, the normal display is stopped, and the LED mounted on the wireless communication terminal device is blinked or lit. Display can be made. Thus, the user can roughly grasp the current battery voltage value, and can delay the decrease in the battery voltage value by reducing the power consumption required for display according to the battery voltage value.

  The notification means may include a plurality of notification forms and a means for selecting one of the notification forms according to an operation input. According to this, according to a user's wish, notification forms, such as a normal display, LED display, and a vibrator display, can be selected. For example, if the user selects an LED display with low power consumption from the beginning, the decrease in the battery voltage value can be reduced.

  The present invention can also be understood from the viewpoint of a program. That is, the present invention is a program that, when installed in a general-purpose information processing device, causes the information processing device to realize a function corresponding to the wireless communication terminal device of the present invention. Thus, if the program of the present invention is installed in a general-purpose information processing apparatus such as a microcomputer chip, the wireless communication terminal apparatus of the present invention can be realized.

  The present invention can also be understood from the viewpoint of a battery table control method. That is, the present invention is a battery table control method including recording a correspondence relationship between a battery voltage value and a low voltage alarm issuing timing in a wireless communication terminal device incorporating a contactless IC card function for communicating with a predetermined terminal. The feature of the present invention resides in that the step of changing the battery table is executed in response to communication with the predetermined terminal.

  In addition, the predetermined terminal is a facility entrance terminal, and the step of changing is a battery for entrance when the alarm output voltage value is set lower than before the facility entrance triggered by communication with the predetermined terminal. The step of changing to a table can be executed.

  In addition, the predetermined terminal is a facility entry terminal, and the changing step includes a step of returning the entrance battery table to a normal battery table before entering the facility upon communication with the predetermined terminal. Can be executed.

  Further, when the predetermined terminal is a facility entry terminal and the battery voltage value after entering the facility is a low voltage value corresponding to turning off the power in view of the normal battery table, the operation is performed after entering the facility. It is possible to execute a step of turning off the power after waiting for completion of the predetermined processing.

  Further, a step of notifying the user of the switching status of the battery table can be executed.

  Further, a step of setting whether or not the battery table can be switched can be set according to an operation input.

  In addition, the step of restricting terminal functions other than the non-contact IC card function in a stepwise manner according to the state of decrease in the power supply voltage value after switching to the entrance battery table can be executed.

  Further, it is possible to execute a step of setting a restriction target function or a restriction order of the restriction step according to an operation input.

  Further, the notifying step can execute a plurality of notification modes, and the step of selecting any one of the plurality of notification modes according to the state of decrease in the battery voltage value after switching to the battery table for entrance. Can be executed.

  Further, the notifying step can execute a plurality of notification forms, and can execute a step of selecting one of the notification forms according to an operation input.

  According to the present invention, the battery voltage value of a wireless communication terminal device with a built-in non-contact IC card function decreases until the original functions (call function, mail transmission / reception function, camera function, etc.) of the wireless communication terminal device are stopped. Even so, the user can determine whether or not the non-contact IC card function can be used.

(First Example)
The configuration of an embodiment of the present invention is shown in FIG. In FIG. 1, an antenna unit 1 for receiving a signal transmitted from a network or transmitting it to the other party via the network, and data for demodulating or transmitting a signal received by the antenna unit 1 via the network. The entire system including a radio unit 2 for modulating the signal to be transmitted to the other party and a voice input / output unit 7 for communicating between the two and a CPU, control of signal transmission / reception, user operation and display, etc. A control unit 3 for controlling data, a memory unit 4 for storing data, a display unit 5 for displaying data, and a man-machine interface unit 6 for controlling user operations.

  In addition, as a built-in non-contact IC card function, a non-contact IC card function such as a control unit 9 that controls communication with an external terminal and data communication with the internal control unit 3 and electronic money or a ticket sales service is used. When using the non-contact IC card unit 8 including the memory unit 10 that can individually store the stored information in each service, the antenna unit 11 for performing communication with the outside during non-contact communication, and the non-contact IC card function And an entrance / exit detection unit 12 for determining whether to enter or participate when the data is obtained from the non-contact IC card unit 8 and used in the ticket sales service.

  The operation of this embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation of this embodiment. FIG. 3 schematically shows the operation of this embodiment. With reference to FIG. 2, a flowchart when passing through a ticket gate using a non-contact IC card will be described. First, since the wireless communication terminal device used the non-contact IC card function when entering through the ticket gate from the standby state (S2), the non-contact IC card unit 8 notifies the control unit 3 of an interrupt. (S3). At this time, in response to the interruption, information is transmitted from the non-contact IC card unit 8 to the control unit 3, and it is determined whether or not the non-contact IC card function is used for the ticket sales service (S4). If so, the process corresponding to the use (e.g. electronic money settlement) is performed (S5), and if it is used as a ticket, the entrance / exit detection unit 12 determines whether the used situation is at the time of entry or at the time of entry. Perform (S6).

  When it is determined that the vehicle has entered, the wireless communication terminal device is switched to the battery table for entry, and the minimum operating voltage value of the wireless communication terminal device, that is, the battery power supply low voltage alarm (hereinafter referred to as LVA) is detected. The voltage value is lowered (S7).

  If it is determined that it is an entry, communicate with an external terminal by non-contact IC communication, and after adjusting the boarding fee (S8), return the battery table for entry to the normal battery table, The LVA detection voltage value is raised (S9).

  Further, after switching to each mode, the battery voltage value is monitored (S10), and if the battery voltage value is lower than the LVA set voltage value, it is determined that the operation limit of the wireless communication terminal device is reached and the power is turned off (S11). Here, the LVA voltage value indicates a voltage value set in each state of the riding mode and the standby mode.

Next, the schematic diagram of FIG. 3 will be described using an example of switching from the battery table 21 to 22. First, as a precondition, it is assumed that state transition occurs in the order of (1) LVA → (2) terminal reset → (3) non-contact communication stop as the battery voltage value decreases for each state of the battery voltage level. Here, as an example of the set voltage value,
(1) LVA (3.3 V): The internal circuit is operating but the forced power supply is turned off (call / display / key operation, etc. are not possible)
(2) Terminal reset (2.9V): A state where the control unit IC of the wireless communication terminal device is not electrically operated due to a decrease in battery voltage (however, only the contactless card unit operates (communication with an external terminal is not possible). Possible))
(3) Non-contact communication stop (2.8V): Non-contact IC card function is also stopped (all wireless communication terminal devices do not function electrically)
And

  During normal standby, the battery voltage value is 3.3V and LVA is generated. Therefore, wireless communication is performed for 0.5V when the battery voltage value drops to the voltage value (2.8V) at which the non-contact IC card unit 8 stops operating. The contactless IC card function is used in a state where the original operation of the terminal device is stopped. In this case, since the terminal is in an OFF state, the wireless communication terminal device is turned off for all functions such as display, and whether or not the contactless function can actually be used is determined not to actually perform contactless communication. It is difficult (21).

  In this embodiment, the LVA detection voltage value is further lowered to a low voltage (3.0 V in this case) at the same time as it passes through the ticket gate, thereby expanding the voltage range in which the wireless communication terminal device can operate, thereby making the contactless IC card function The range in which it can be recognized that is operating is expanded (22).

  The operation when switching the battery table upon entering may be automatically switched when a communication interrupt is detected, or displayed to enable the user to recognize that the mode has been switched. Notification may be made by voice or voice. In addition, the user may select whether or not to change the battery table for entry. When returning the battery table to the normal standby one at the time of participation, notification may be made in the same manner.

  In addition, the battery voltage value decreases in the state of the entrance battery table, and when it enters, the battery table is switched to the normal battery table, but at this time, it is below the LVA detection voltage value (3.3 V). If this is the case, after finishing the checkout process at the time of entry, the terminal power supply is turned off because the voltage is below the LVA voltage value. Since the terminal is suddenly turned off in this state, the user may be notified that the battery voltage value has decreased and cannot be operated.

  Further, according to the present invention, it is sufficient that the user can recognize whether or not the non-contact IC card function can be used even if the battery voltage value is lowered. Therefore, the method for causing the user to recognize is not limited to display only. For example, the present invention can be realized simply by blinking or lighting an LED lamp or the like mounted on a wireless communication terminal device without displaying.

(Second embodiment)
A second embodiment will be described with reference to FIGS. FIG. 4 is a flowchart showing the operation of the second embodiment. FIG. 5 is a schematic diagram showing the operation of the second embodiment. As for the first embodiment, the operation voltage value of the wireless communication terminal device is expanded by lowering the LVA detection voltage value at the time of admission, but when the battery voltage value decreases after admission, When a wireless communication terminal device performs an operation that consumes a large amount of current, such as a mail transmission / reception function or a camera function, a situation may occur in which the wireless communication terminal device suddenly resets due to a sudden drop in battery voltage. Conceivable.

  In view of such a possibility, the second embodiment limits the operation function of the wireless communication terminal device according to the voltage value after reaching the LVA set voltage value at the time of standby.

  First, the wireless communication terminal device passes through the ticket gate from the standby state (S22), and an interrupt is notified from the non-contact IC card unit 8 to the control unit 3 (S23). At this time, it is determined whether or not the contactless IC card function is used for the ticket sales service due to the interruption (S24). Otherwise, processing corresponding to the purpose (such as electronic money settlement) is performed (S25). If it has been used as a boarding ticket, it is determined whether the used situation is at the time of entry or at the time of entry (S26).

  If it is determined that the battery is entered, the current battery voltage value is monitored (S27). If the battery voltage value is lower than the standby LVA voltage value (3.3V) (S28), the battery table is entered. The battery function table is switched, and the operation function is restricted according to the battery voltage value (S29).

  If it is determined that the vehicle has entered, after communicating with the external terminal through non-contact IC communication and adjusting the boarding fee (S30), the entry battery table is returned to the normal battery table, and the LVA The detection voltage value is raised (S31).

  Next, the schematic diagram of FIG. 5 will be described. When entering through the ticket gate, the battery table is switched to the entry battery table 31. When reaching the normal LVA voltage value until reaching the normal LVA voltage value, the LVA voltage value is reached after entry In order to reduce the current consumption of the wireless communication terminal device, the wireless communication terminal device is restricted in function according to the battery voltage value.

  In the example of FIG. 5, (1) the call function is stopped at each stage of the battery voltage value, the non-contact IC card function operation availability is notified by display, and (2) various functions (eg, camera, key operation, etc.) are stopped. The non-contact IC card function operation availability is notified by display, (2) the display function is stopped, and the non-contact IC card function operation availability is notified by an LED lamp. In this case, the terminal power is turned off (3.0 V in this case) and the function is stopped, but the user can recognize whether or not the non-contact IC card function can be operated until the terminal power is turned off.

  In addition, since the function is limited to suppress the current consumption after the LVA voltage value, the battery life is extended as a result, and the time that the non-contact IC card function after the LVA voltage value can be used is extended. The feature is different from the first embodiment.

  The information that the function is restricted may be notified to the user as appropriate by means such as a display, or the user may be able to set the degree of function restriction (example: Key operation is always possible). Alternatively, the user may be allowed to set a function restriction order (eg, camera function → mail transmission / reception function → call function). In addition, the function restriction may be such that the fixed function may be stopped when the LVA voltage value (3.3 V) is reached (example: call + display + camera).

(Third embodiment)
A third embodiment will be described with reference to FIG. FIG. 6 is a schematic diagram showing the operation of the third embodiment. As for the third embodiment, the LVA set voltage value is switched by means of notifying means for non-contact IC card function operation at the time of participation by providing various methods for recognizing whether or not the non-contact IC card function can operate when the battery voltage value drops. It is. When the LVA voltage value (3.3 V) at the normal standby is reached after passing through the ticket gate, the power is turned off and the function is stopped, but notification is made by the notification means set by the user when entering in that state.

  Since the current consumption differs depending on the notification means, it is possible to efficiently perform the operation availability range of the non-contact function by setting the battery table 32 with different LVA detection for each current amount of each means.

  In the third embodiment, the notification means is selected from (1) display (sight), (2) sound (hearing), and (3) vibration (tactile sense). As a feature of the third embodiment, by having various notification means, the user can make a selection according to the situation and application (applicable to disabled people).

  According to the present invention, it is possible to reduce the probability that the non-contact IC card function built in the wireless communication terminal device stops functioning. Therefore, the convenience to the user is improved, and the wireless communication terminal device with built-in non-contact IC card function is provided. Can contribute to the spread of
