Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device as a mobile terminal device, and FIG. 1 is a block diagram showing basic components of the mobile phone device.
This cellular phone device is provided with a connection function monitoring function and a non-contact IC processing function in addition to a telephone call function, an electronic mail function, an Internet connection function (Web access function), and the like. This connection state monitoring function detects a connection state of a UIM (User Identity Module) card in which subscriber information and the like are recorded in the same manner as the SIM card at a predetermined timing, and an access error process according to the detection of the absence of connection. Is set to the terminal lock state that restricts the use of the device itself. The non-contact IC processing function constitutes an electronic money function, and performs payment with electronic money by performing non-contact communication with a transaction terminal with a reader / writer.

  The CPU 1 is a core central processing unit that controls the overall operation of the mobile phone device in accordance with various programs in the storage unit 2. The storage unit 2 has a program area and a data area. In this program area, a program for realizing the present embodiment is stored in accordance with an operation procedure shown in FIG. The recording medium 3 is a portable memory that is detachably mounted via the external memory slot 4 and supplies various data programs externally. For example, the recording medium 3 includes smart media, an IC card, and the like. The memory 4 is an internal memory having a work area, and is composed of, for example, DRAM, SDRAM (Synchronous DRAM), etc. Various data in the memory 5 are saved in the storage unit 2 as necessary.

  The telephone communication unit 6 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna constituting the radio unit, demodulates it to a received baseband signal, and then transmits the signal via the acoustic control unit 7 Sound is output from the speaker 8. Further, the telephone communication unit 6 takes in the voice data input from the receiving microphone 9 from the acoustic control unit 7, encodes it into a transmission baseband signal, gives it to the transmission side of the transmission / reception unit, and transmits and outputs it from the antenna. On the other hand, the display data received and acquired via the telephone communication unit 6 by the e-mail function and the Internet connection function is given to the main display unit 11 such as an LCD (Liquid Crystal Display) via the display control unit 10 for display output. The The sub display unit 12 displays the current date and time, a simple message, an icon, and the like.

  The key operation unit 13 performs dial input, character input, command input, and the like. The CPU 1 executes processing according to a key input signal from the key operation unit 13. The notification unit 14 includes a speaker for notification of incoming call notification, an LED (light emitting diode), and a vibration motor. The notification unit 14 is driven when a call / mail is received to notify the incoming call, and is also driven when an alarm is notified. An RTC (real-time clock module) 15 constitutes a clock unit, and the CPU 1 acquires the current date and time from the RTC 15.

  The non-contact IC processing unit 16 constitutes an electronic money function, has a memory unit and a coil antenna unit, and transmits / receives data to / from a transaction terminal (not shown) with an IC reader / writer by weak radio waves. Do. The memory unit has a money balance memory and the like, and the coil antenna unit uses electromotive force electromagnetically induced by the received radio wave as the operating power of the non-contact IC processing unit 16. It starts based on the electromotive force from the antenna unit, and performs processing such as storing the current transaction information as a usage history together with updating the money balance with the IC reader / writer. The excitation current detection circuit 16A detects a current excited by electromagnetic induction, and the CPU 1 determines whether or not the non-contact IC processing unit 16 is operating according to a detection signal from the excitation current detection circuit 16A. The electronic money function can be arbitrarily switched between an unusable locked state and a usable state by function on / off operation.

  The UIM card 17 is an IC card that is detachably mounted via a card slot 18, and subscriber information and the like are recorded in the same manner as the SIM card. The CPU 1 operates the above-described connection state monitoring function and detects the connection state as to whether the UIM card 17 is connected to the card slot 18 at every predetermined timing. In this case, the CPU 1 accesses the card slot 18 to check whether or not the UIM card 17 is connected. When the CPU 1 detects no connection due to a connection failure or the like, the CPU 1 executes an access error process and uses the telephone device itself. The terminal lock state to be restricted is set. The CPU 1 determines whether or not the non-contact IC processing unit 16 is operating based on the detection signal from the excitation current detection circuit 16A when detecting the connection of the UIM card 17, and when the excitation current is detected, the non-contact IC processing unit 16 operates. The monitoring operation of the connection state monitoring function is controlled by determining that it is in the middle.

FIG. 2 is a diagram for explaining a monitoring operation for monitoring the connection state of the UIM card 17.
The CPU 1 detects the connection state of the UIM card 17 at every predetermined timing (for example, at an interval t of 5 seconds), and the presence or absence of the operation of the non-contact IC processing unit 16 at each detection timing (whether the electronic money function is being used). Is determined. At this time, if the non-contact IC processing unit 16 is operating (using electronic money) at the detection timing, the detection operation is temporarily suspended and the detection timing is shifted (postponed) for a predetermined time. In the example shown in the figure, the case of delaying for 3 seconds is shown, but a maximum of 6 seconds can be shifted. That is, even if the detection timing is postponed for 3 seconds, if it is detected that the UIM card 17 is not connected, it is postponed again for 3 seconds to detect whether the UIM card 17 is connected.

  Next, the operation concept of the cellular phone device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 3 is a flowchart showing a UIM card check process for detecting a connection state of the UIM card 17 that is started every five seconds.
First, the CPU 1 checks whether or not the electronic money function is locked in an unusable state (step A1). If the electronic money function is locked, whether or not the UIM card 17 is connected via the card slot 18 is checked. Is checked (step A10). If it is detected that the UIM card 17 is normally connected (YES in step A11), this flow ends normally. However, even if the UIM card 17 is not attached or is attached, it is caused by poor contact. If no connection is detected (NO in step A11), the process proceeds to an access error process, the current process is stopped, and the terminal is locked.

 On the other hand, if the electronic money function is unlocked and set to a usable state (NO in step A1), the CPU 1 accesses the non-contact IC processing unit 16 constituting the electronic money function, and the excitation current thereof. Based on the detection signal from the detection circuit 16A, the presence or absence of operation of the non-contact IC processing unit 16 is checked (step A2). In this case, it is determined whether or not the non-contact IC processing unit 16 is operating based on the presence / absence of the excitation current due to the received radio wave. If it is not operating (NO in step A3), the UIM is the same as described above. The process proceeds to determination step A10 for checking whether or not the card 17 is connected. If the non-contact IC processing unit 16 is operating (YES in step A3), the “retry completed flag” provided in the work area of the memory 5 is set. After turning off (step A4), the process waits for 3 seconds to temporarily hold the current detection operation (step A5).

 In other words, as described above, if the non-contact IC processing unit 16 is in operation at the timing of detecting whether or not the UIM card 17 is connected, the detection timing can be postponed for a maximum of 6 seconds. Turn off the "Retry flag". Then, after delaying this detection timing for 3 seconds, the result of checking again whether or not the UIM card 17 is connected (step A6), if it is detected that the UIM card 17 is connected (YES in step A7), the current connection error is detected. Is recognized as an error due to a momentary connection failure and ends normally. However, if it is detected that the UIM card 17 is not connected even after being postponed for 3 seconds (NO in step A7), the “retry flag” is set. It is determined whether it is on (step A8).

 Now, since the “retry completed flag” is turned off when the first 3 seconds have elapsed (NO in step A8), the process proceeds to the next step A9, and after the “retry completed flag” is turned on, another 3 seconds. To return to step A5. If the presence of connection of the UIM card 17 is detected after the delay of 6 seconds (YES in step A7), it is recognized as a connection error due to a momentary connection failure and ends normally. When it is detected that the UIM card 17 is not connected (NO in step A7), the process proceeds to the access error process, the current process is stopped, and the terminal is locked.

  As described above, in the first embodiment, the CPU 1 detects the connection state of the UIM card 17 at a predetermined timing, and when detecting no card connection, executes the access error process to set the terminal locked state. At that time, it is determined whether or not the non-contact IC processing unit 16 is in operation based on the presence or absence of the excitation current due to the received radio wave when the connection of the UIM card 17 is detected. Since the detection is extended and the detection is extended, the main body of the device collides with the reader / writer when using the non-contact IC processing unit 16 (when using electronic money), and the card is instantaneously connected by the impact. Even if it becomes defective, it is possible to avoid a malfunction due to the momentary detection of the connection failure, and it is possible to eliminate the recovery work associated with this malfunction.

 In this case, the electronic money function (non-contact IC processing unit 16) can be arbitrarily switched between an unusable locked state and a usable state by a function on / off operation, and the electronic money function is unlocked. Therefore, the presence / absence of the operation of the non-contact IC processing unit 16 can be omitted when the lock is set for the electronic money function.

In the first embodiment described above, the UIM card check process for detecting the connection state of the UIM card 17 is executed every 5 seconds, but this time interval is arbitrary, and the UIM card 17 It is determined whether or not the non-contact IC processing unit 16 is in operation when the connection is detected. If it is in operation, the current detection timing is temporarily suspended and the detection is extended for at least 3 seconds. The extension period is arbitrary as long as the influence of the impact can be avoided, and is not limited to extending the current detection timing, and the detection may be canceled. Furthermore, the current detection timing may not be extended or invalidated, and the current process may be canceled and the access error process itself for setting the terminal locked state may be canceled.
(Example 2)

The second embodiment of the present invention will be described below with reference to FIG.
In the first embodiment described above, if the non-contact IC processing unit 16 is operating when the connection of the UIM card 17 is detected, the connection detection timing is temporarily suspended and extended. In the embodiment, if the non-contact IC processing unit 16 is operating when the connection of the UIM card 17 is detected, the connection detection operation of the UIM card 17 is retried for a predetermined number of times.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 4 is a flowchart showing the UIM card check process in the second embodiment, which is started every 5 seconds.
First, the CPU 1 sets an initial value “0” in the “retry count” provided in the work area of the memory 5 (step B 1), and then checks whether the UIM card 17 is connected via the card slot 18 (step B 1). Step B2). If it is detected that the UIM card 17 is normally connected (YES in step B2), the flow ends normally. However, even if the UIM card 17 is not attached or is attached, it is caused by poor contact. When no connection is detected (NO in step B2), it is checked whether or not the electronic money function is locked in an unusable state (step B3). If the electronic money function is locked, access error processing is performed. Move to stop the current process and set the terminal locked.

  If the electronic money function is unlocked and set to a usable state (NO in step B3), the CPU 1 determines whether the non-contact IC processing unit 16 is based on the detection signal from the exciting current detection circuit 16A. The presence / absence of the operation is checked (step B5). If it is not operating (NO in step B6), the process proceeds to the access error process as described above, the current process is stopped, and the terminal lock state is set. If the non-contact IC processing unit 16 is operating (YES in step B6), an update process for adding “1” to “retry count” is executed (step B7), and then the “retry count” is “3”. Is checked (step B8).

  Since the “retry count” is “1” at the time of the first update, the process returns to step B2 to check the card connection. Thereafter, the card connection check is repeated until the “retry count” reaches “3”. In the process of repeating this connection check, if the presence of card connection is detected (YES in step B3), the process ends normally, but even before the “retry count” reaches “3”, non-contact IC processing is performed. If no card connection is detected when the operation of the unit 16 is finished (NO in step B6), it is recognized that the cause of the connection error is not an instantaneous connection failure due to an impact, and the terminal is locked. . Similarly, even when the non-contact IC processing unit 16 is in operation, when the “retry count” reaches “3” with no card connection detected (YES in step B8), the cause of the connection error is due to an impact. Recognizing that there is no instantaneous connection failure, the terminal is locked.

  As described above, in the second embodiment, if the contactless IC processing unit 16 is operating when the connection of the UIM card 17 is detected, the connection detection operation of the UIM card 17 is retried for a predetermined number of times. Therefore, even if the device body collides with the reader / writer when the non-contact IC processing unit 16 is used (when electronic money is used), even if the card momentarily fails to connect due to the impact, the connection detection operation In the process of repeating several times, it is possible to detect the presence of a card, and, as in the first embodiment described above, it is possible to avoid malfunction due to instantaneous connection failure detection.

  In this case, the CPU 1 counts the “retry count” in order to repeat the card connection check three times in succession, and also operates the non-contact IC processing unit 16 even before the “retry count” reaches “3”. If no card connection is detected when the operation ends, it is recognized that the cause of the connection error is not an instantaneous connection failure due to an impact, and the terminal is locked. Similarly, even when the non-contact IC processing unit 16 is in operation, when the “retry count” reaches “3” with no card connection detected, the cause of the connection error is an instantaneous connection failure due to an impact. It can be recognized that the terminal is locked.

 Also in the second embodiment, similarly to the first embodiment described above, the electronic money function (non-contact IC processing unit 16) can be arbitrarily switched between an unusable locked state and a usable state by a function on / off operation. Since it is possible to detect whether or not the non-contact IC processing unit 16 is operating on the condition that the electronic money function is unlocked, when the electronic money function is set to lock, the non-contact IC processing unit 16 The presence / absence detection of operation can be omitted.

In the first and second embodiments described above, the presence or absence of operation of the non-contact IC processing unit 16 is determined based on the detection signal from the excitation current detection circuit 16A. Data stored in the unit 16 (for example, card balance, usage history, etc.) is periodically read out, and whether or not the non-contact IC processing unit 16 is operating (whether it is in use) is determined based on whether or not the data changes. You may make it do.
In the first and second embodiments described above, the case where the non-contact IC processing unit 16 is used as an electronic money function is exemplified. However, the present invention is not limited to electronic money. For example, a boarding ticket, a commuter pass, personal authentication, etc. Even if it is used in the same way, it can be similarly applied.

   In the first and second embodiments described above, the UIM card check process for detecting whether or not the UIM card 17 is connected is executed. For example, the recording medium 3 attached to the external memory slot 4 or the like The present invention can be similarly applied to the case where the presence / absence of connection of a recording medium other than the UIM card is checked or the presence / absence of the battery pack is sequentially checked.

  In addition, in the first and second embodiments described above, the present invention is not limited to a mobile phone device with a connection state monitoring function, but may be, for example, a portable terminal device such as a PDA with a connection state monitoring function, an electronic camera, an electronic watch, or a music player. Even if it exists, it is applicable similarly.
