Description

  The present invention relates to a mobile phone terminal with a non-contact IC card function and a function restriction method and program based on the remaining battery capacity, and in particular, in a mobile phone terminal with a non-contact IC card function, when the battery capacity of the terminal is low, the power of the terminal is Non-contact that restricts the function even if it is turned off, secures a power supply so that the non-contact IC card function can be used, allows the authentication function of the non-contact IC card to continue to be used, and avoids the function restriction of the authentication function for the user The present invention relates to a mobile phone terminal with an IC card function and a function restriction method and program based on remaining battery capacity.

  Non-contact IC cards are used as authentication means that are difficult to forge or alter for the purpose of paying call charges on public telephones, paying train charges such as JR, and ID recognition of products.

  By mounting the functions of such a contactless IC card that is convenient and necessary for social life at any time on a mobile phone terminal that is also carried as a necessary item for social life, it becomes a single portable item and is always carried around. There will be one item instead of two, making it a convenient portable product. However, if the non-contact IC card and the mobile phone terminal are combined, the power consumption of the power source increases and a large capacity battery is required.

  As a conventional technique, an attempt has been made to save power by saving current consumption of a power source as a single mobile phone terminal itself.

  As a conventional technique, there is JP-A-10-107914 (see Patent Document 1).

  This detects the remaining amount of the battery, and when the battery voltage value is equal to or lower than a specified voltage value, the current process is temporarily suspended.

  Moreover, there exists Unexamined-Japanese-Patent No. 2001-298533 as a prior art (refer patent document 2).

  When the battery monitoring unit detects that the battery is below a predetermined remaining amount, the communication unit is stopped and predetermined information registered in the storage unit is displayed on the display unit.

  Further, as a conventional technique, there is JP-A-2002-199092 (see Patent Document 3).

  This is because the control unit receives the remaining amount of the battery from the remaining amount detection unit, compares the received remaining amount with the reference value, and when the remaining amount reaches the reference value, it communicates with the outside via the transmission / reception unit. When an instruction for performing an operation other than communication with the outside is input via the key input unit, an operation other than communication with the outside is executed according to the input instruction.

JP-A-10-107914 ([Summary] and paragraph [0038]) JP 2001-298533 A ([Summary] and paragraph [0006]) JP 2002-199092 A (paragraph [0016])

It is difficult to mount a power supply circuit that takes power from a received radio wave in a mobile phone terminal that is required to be integrated.

  The reason is that a large loop antenna is required and the power supply circuit for rectifying the radio signal becomes large.

  The second problem is that when a non-contact IC card is used for entrance / exit of a ticket gate such as a station, inconvenience arises in entering or leaving.

  The reason for this is that when the remaining battery capacity is low and the power is turned off, you cannot enter or leave, so to use the contactless IC card function, charge the battery of the mobile phone terminal until the function can be restarted This is because the ticket gate must be passed by waiting or paying cash without using the contactless IC card function.

  The third problem is that inconvenience occurs when the customer uses the contactless IC card to clear the shopping.

  The reason is that payment cannot be made when the battery capacity of the mobile phone terminal decreases and the power is turned off.

  The fourth problem is that the current consumption increases because a non-contact IC card function is added.

  The reason is that the mobile phone terminal has various additional functions in addition to the conventional communication function, and the current consumption increases, and a large capacity battery is required. Therefore, the current consumption cannot be increased. is there.

  The fifth problem is that in Patent Document 1, when the battery voltage falls below a set value, the function to tell the user whether to use the non-contact IC card authentication function or the communication function of the mobile phone terminal with priority is provided. The user cannot select the function to be prioritized and continue to use the authentication function.

  The reason is that the remaining amount of the battery is detected, and when the battery voltage value is equal to or lower than the specified voltage value, the current processing is merely suspended.

  The sixth problem is that in Patent Document 2, when the battery voltage falls below a set value, the function to tell the user whether to use the authentication function of the contactless IC card or the communication function of the mobile phone terminal with priority is provided. In addition, the user cannot select the function to be prioritized and continue to use the authentication function.

  The reason is that the communication monitoring unit only stops when the battery monitoring unit detects that the battery is below a predetermined remaining amount.

  The seventh problem is that in Patent Document 3, when the battery voltage becomes lower than the set value, the function to tell the user whether to use the non-contact IC card authentication function or the communication function of the mobile phone terminal with priority is provided. In addition, the user cannot select the function to be prioritized and continue to use the authentication function.

The reason is that the remaining battery level is compared with the reference value, and when the remaining battery level reaches the reference value, communication with the outside via the transmitter / receiver is prohibited and only operations other than communication with the outside are executed. Because there is.

  Referring to FIG. 1, a mobile phone terminal 30 with a non-contact IC card function includes a mobile phone terminal unit 20 that performs a communication function and a non-contact IC card function unit 10 that performs an authentication function. In this way, the communication function of the mobile phone terminal unit 20 and the authentication function of the non-contact IC card function unit 10 can be selected and separated for use.

  The non-contact IC card function unit 10 matches the interface voltage when transmitting / receiving data to / from the antenna unit 11 that transmits / receives authentication data, the control unit 12 that controls the IC card operation including authentication information, and the mobile phone terminal unit 20. It comprises a level conversion circuit 13 and a peripheral circuit 14 to be operated. The memory 26 stores various programs executed by a computer (not shown) in the control unit 25.

  The mobile phone terminal unit 20 includes an antenna unit 21 that detects transmission and reception waves, a radio unit 22 that transmits and receives radio signals, a display unit 23 that displays character / image information of the mobile phone terminal 30 with a non-contact IC card function, and input / output operations. A key switch operation unit 24 for performing the above operation, a control unit 25 for controlling the above operation, a memory 26 for storing information, a battery 27 for supplying power, and a speaker 28.

  The control unit 25 of the mobile phone terminal unit 20 detects the remaining battery capacity of the battery 27. When the battery voltage becomes equal to or lower than the set value V1, the control unit 25 warns to inform the user whether to use the authentication function of the non-contact IC card function unit 10 or the communication function of the mobile phone terminal unit 20 with priority. Sound or vibration is generated, and further display notification to the display unit 23 is performed. Thereby, the user can select each function to be prioritized on the display unit. Then, by selecting the authentication function using the operation unit 24, the authentication function of the non-contact IC card function unit 10 can be continuously used.

  In this way, since the function is limited by monitoring the battery capacity of the mobile phone terminal 30 with the non-contact IC card function, the authentication function of the non-contact IC card is continuously performed without losing user data. Is available.

  Since the non-contact IC card is operated without a power source, the power must be taken from the received radio wave, and conventionally a large loop antenna and a power supply circuit for rectifying the radio signal are required. For this reason, the mobile phone terminal 30 with the non-contact IC card function becomes large, which is a harmful effect on the terminal product size.

  Further, the contactless IC card operates even when the power of the mobile phone terminal 30 with the contactless IC card function is turned off, but the operation is not guaranteed when the battery capacity is low voltage. It is an object to be solved by the present invention that the contactless IC card function can be used even when the power of the mobile phone terminal 30 with the contactless IC card function is turned off and the battery voltage is not more than the set value V1.

  Therefore, the control unit 25 detects that the battery voltage of the mobile phone terminal 30 with the non-contact IC card function has become equal to or lower than the set value V1. And the control part 25 enables it to select the function which can be used according to a user's need. By doing so, power is supplied from the battery 27 only to functions that can be used. With such a configuration, wasteful power consumption is suppressed and the authentication function of the non-contact IC card can be used.

  As described above, in the mobile phone terminal 30 with the non-contact IC card function, when the remaining battery capacity of the mobile phone terminal 30 with the non-contact IC card function decreases, the authentication function of the non-contact IC card can be used. As an effect, even if the power of the mobile phone terminal 30 with the non-contact IC card function is lowered, the function is restricted, the power is secured so that the non-contact IC card function can be used, and the authentication function of the non-contact IC card is continued. It can be used, and the function restriction of the authentication function for the user can be avoided.

  Next, the operation of the first embodiment of the present invention will be described with reference to FIG. 2, FIG. 3, FIG. 4, and FIG.

  The control unit 25 controls the power supply of the communication function of the mobile phone terminal unit 20 until the input scheduled time for using the communication function of the mobile phone terminal unit 20 (step S9).

  As the control of the power supply, in order to further reduce the power consumption, the power supply to the communication function is not performed until the scheduled time for using the communication function of the mobile phone terminal unit 20. And it can be set as the structure which supplies a power supply to the communication function of the mobile telephone terminal part 20 at the time of using scheduled time. That is, the communication function of the mobile phone terminal unit 20 can be temporarily stopped.

  Further, power may be supplied to the communication function of the mobile phone terminal unit 20 until the scheduled time. In this case, when the scheduled time comes, power supply to the communication function of the mobile phone terminal unit 20 is stopped.

  Further, in the case of selection B, the operations of the antenna unit 21, the radio unit 22, and the operation unit 24 of the mobile phone terminal unit 20 are restricted, and the selection is made so that the authentication function of the non-contact IC card unit 10 can be utilized. . For this reason, the control unit 25 controls the power supply for operating only the non-contact IC card function unit 10 and the display unit 23, the control unit 25, the memory 26, the battery 27, and the speaker 28 of the mobile phone terminal unit 20. (Step S4). At this time, the control unit 25 of the mobile phone terminal unit 20 is controlled so that power is not supplied to the antenna unit 21 and the radio unit 22 of the mobile phone terminal unit 20.

  Next, the user inputs a scheduled time for using the non-contact IC card (step S5).

  The control unit 25 controls the power supply of the non-contact IC card unit 10 until the scheduled use time of the input non-contact IC card (step S6). Thereby, the non-contact IC card unit 10 can effectively consume power.

  As the control of the power supply, the power supply is not performed until the scheduled time for use of the non-contact IC card from the viewpoint of further reducing the power consumption. And it can be set as the structure which supplies a power supply at the time of scheduled use time. That is, the authentication function of the non-contact IC card 10 can be temporarily stopped.

  Moreover, you may make it the structure which supplies a power supply to the non-contact IC card part 10 until scheduled time. In this case, when the scheduled time comes, power supply to the authentication function of the non-contact IC card 10 is stopped.

  In FIG. 4, when the battery voltage reaches the battery voltage V <b> 1 set for performing function selection, the function selection is performed as described above. The selected function can be used up to the voltage of V2 which detects the low voltage battery alarm of the device.
