  FIG. 1 is a diagram for explaining a lock function of the mobile terminal 1 according to the present embodiment. The mobile terminal 1 of the present embodiment stores an action range 17 (shaded portion in FIG. 1) that is a range in which the user of the mobile terminal 1 behaves on a daily basis, and when the position information is not included in the action range 17, That is, when the mobile terminal 1 goes out of the action range 17, a lock setting function for setting a lock state in which a part of the functions of the mobile terminal 1 is locked is provided.

  As described above, when the mobile terminal 1 goes out of the action range 17, the mobile terminal 1 is automatically set to the locked state, but the release of the locked state is automatically performed based on the position information of the mobile terminal 1. If the user authentication of the user who operates the mobile terminal 1 is successful, the locked state of the mobile terminal 1 can be released regardless of the position information of the mobile terminal 1. This is because it is inconvenient if a legitimate user cannot use the mobile terminal 1 even outside the action range 17.

  In addition, since the act of adding a new range to the action range 17 becomes a burden on the user, the mobile terminal 1 of the present embodiment includes position information measured after the locked state is released in the action range 17. If not, an additional range centered on the measured position information is added to the action range 17.

  In addition, since there is no need to include a range where the frequency of use of the user is low in the action range 17, the mobile terminal 1 of the present embodiment has a preset designated date and time when the mobile terminal 1 is measuring. When the condition is met, the position information stored in the portable terminal 1 is analyzed according to a predetermined method, and a function of deleting a range with a low frequency of use by the user from the action range 17 is provided.

  The user's action range 17 used by means such as the lock setting means 13 of the mobile terminal 1 is stored in the memory 1 d of the mobile terminal 1. The action range 17 is composed of a combination of figures on the map, and one figure constituting the action range 17 is expressed in a predetermined format (for example, a vector image), and coordinates indicating the position of the figure are longitude and latitude.

  The action range 17 is not stored in the memory 1d of the mobile terminal 1 in advance, and the mobile terminal 1 defaults before the user uses the function of automatically setting the mobile terminal 1 to the locked state based on the position information. The action range 17 is set. Although the user may manually set the default action range 17 while referring to the map, in this embodiment, the default action range 17 is automatically stored in the memory by the action range setting unit 16 provided in the mobile terminal 1.

The control means 10 of the portable terminal 1 is automatically activated after the power of the portable terminal 1 is turned on. When the control means 10 of the portable terminal 1 is activated, the control means 10 of the portable terminal 1 has the action range 17 stored in the memory 1d. (S1).

  When the action range 17 is not stored in the memory 1d, the control means 10 of the portable terminal 1 calls the action range setting means 16 and sets a default action range 17 in the memory 1d (S6). ) Is executed by the action range setting means 16, and this procedure is terminated.

  The default action range setting process (S6) for setting the default action range 17 in the memory 1d takes several days, and after the default action range setting process (S7) is completed, the control means 10 of the mobile terminal 1 When activated, the subsequent steps are executed.

  When the action range 17 is stored in the memory 1d in S1 of FIG. 5, the control means 10 of the portable terminal 1 sets the unlocking means 14 of the portable terminal 1 after setting the portable terminal 1 to the locked state (S2). Called to cause the unlocking means 14 to execute the unlocking process (S3) for releasing the locked state of the portable terminal 1.

  When the unlocking means 14 of the mobile terminal 1 unlocks the locked state of the mobile terminal 1, the control means 10 of the mobile terminal 1 calls the lock setting means 13 of the mobile terminal 1 and based on the position information of the mobile terminal 1. When the lock setting unit 13 executes lock setting processing (S4) for automatically setting the mobile terminal 1 in the locked state, and the lock setting unit 13 sets the mobile terminal 1 in the locked state, the process returns to S3 in FIG. After causing the unlocking means 14 to execute the release process (S3), the action range adding means 16 is caused to execute an additional range setting process (S4) for setting the additional range to the action range 17.

  Further, the control means 10 of the mobile terminal 1 periodically monitors the time measured by the clock circuit of the mobile terminal 1, and when an event occurs in which the date and time of the clock circuit meets a preset date and time condition, Regardless of whether or not the mobile terminal 1 is in the locked state, the behavior analysis means 15 is called to analyze the positional information stored in the memory 1d of the mobile terminal 1, and the range in which the user is less frequently used is defined as the behavior range. The behavior analysis process (S6) to be deleted from the behavior analysis means 15 is executed by the behavior analysis means 15.

  Note that, for example, when an operation for terminating the control means 10 of the mobile terminal 1 is performed (S8), such as when the power of the mobile terminal 1 is turned off, the procedure illustrated in FIG. 5 ends.

  Next, the position measuring unit 11 will be described. The position measuring means 11 provided in the portable terminal 1 is a means for measuring position information at this time when receiving an instruction from another means of the portable terminal 1.

  As a method for acquiring position information, a central device arranged in a public wireless network according to communication time with an A-GPS (assistant GPS) using a GPS circuit 1f or a relay point at which the mobile terminal 1 can wirelessly communicate. There is a method of measuring position information and acquiring position information from the central device, but any method may be used as long as the position information can be acquired.

  Next, the position information storage unit 17 of the mobile terminal 1 will be described. The position information storage unit 17 provided in the portable terminal 1 is a unit that executes a process of storing the measured position information in the memory 1d when the position measurement unit 17 measures the position information.

  Next, the speed measuring unit 12 of the mobile terminal 1 will be described. The speed measuring means 12 provided in the mobile terminal 1 is a means for measuring speed information of the mobile terminal 1 at this time when receiving an instruction from other means of the mobile terminal 1.

  As a method for measuring the speed information of the mobile terminal 1, if it can be ensured that the initial speed of the mobile terminal 1 is “0 m / s”, the speed information of the mobile terminal 1 is calculated from the acceleration obtained from the three-dimensional acceleration sensor 1 k. However, since it is difficult to guarantee that the initial speed of the mobile terminal 1 is “0 m / s”, in the present embodiment, when position information is delivered from other means of the mobile terminal 1, a certain time elapses. After that, the position information is measured by the position measurement unit 11 and the speed information of the portable terminal 1 is measured from the distance between the position information delivered from the control unit 10 and the position information after a certain time and the certain time. ing.

  Next, the lock setting means 13 of the mobile terminal 1 will be described. The lock setting means 13 of the mobile terminal 1 is a means for executing a lock setting process for automatically setting the mobile terminal 1 in a locked state in which a part of the functions of the mobile terminal 1 is locked according to the position information of the mobile terminal 1. is there.

  FIG. 6 is a flowchart for explaining the lock setting process. When the lock setting means 13 of the portable terminal 1 is called from the control means 10 of the portable terminal 1, first, the position measuring means 11 is instructed to measure the position information, and the position measuring means 11 measures the position information ( S10) After the position information storage means 17 stores the position information measured by the position measurement means 11 in the memory 1d (S11), the position information measured by the position measurement means 11 is transferred to the speed measurement means 12 to measure the speed. The means 12 is made to measure speed information (S12).

  When the speed measurement unit 12 measures the speed information, the lock setting unit 13 of the mobile terminal 1 determines whether or not the position information measured by the position measurement unit 11 is included in the action range 17 stored in the memory 1d. Confirm (S13).

  When the position information measured by the position measuring unit 11 is not included in the action range 17 stored in the memory 1d, the lock setting unit 13 of the mobile terminal 1 sets the mobile terminal 1 to the locked state (S16). End this procedure.

  When the position information measured by the position measuring unit 11 is included in the action range 17 stored in the memory 1d, the lock setting unit 13 of the mobile terminal 1 measures the time until the next position information is measured. A time interval is calculated (S14).

  The measurement time interval indicating the time until the next position information is measured may be a constant, but in the present embodiment, in order to suppress the power consumption of the portable terminal 1, the speed information measured by the speed measuring means 12 described later is used. The measurement time interval is determined so as to be inversely correlated.

  The measurement time interval is determined so as to be inversely correlated with the speed information measured by the speed measuring unit 12. The mobile terminal 1 until the next position information is acquired from the speed information measured by the speed measuring unit 12. When the mobile terminal 1 speed information is slow, the mobile terminal 1 travel distance becomes short. Therefore, when the measurement time interval is long and the mobile terminal 1 speed information is fast, the mobile terminal 1 This is because it is desirable to shorten the measurement time interval.

  When the measurement time interval is calculated, the lock setting means 13 of the portable terminal 1 measures time using a clock circuit (S15), and when the time reaches the measurement time interval, the lock setting unit 13 returns to the top of FIG.

  6 is performed, the lock setting unit 13 of the mobile terminal 1 acquires the position information of the mobile terminal 1 from the position measurement unit 11, and the position information is included in the action range 17. The position information of the mobile terminal 1 is not included in the action range 17, and when the position information of the mobile terminal 1 is not included in the action range 17, the mobile terminal 1 is set to the locked state. Will perform the action.

  Next, the unlocking means 14 of the portable terminal 1 will be described. The unlocking unit 14 of the portable terminal 1 is a unit that executes user authentication when an operation for releasing the locked state is performed, and releases the locked state when it is determined that the user authentication is valid. When an operation for releasing the lock state is performed, user authentication is performed. When the user authentication is successful, the lock state is released, and the position measurement unit 11 is used to measure the position information. When the position information is not included in the action range 17, the additional range centering on the position information measured by the position measurement unit 11 is added to the action range 17.

  FIG. 7 is a flowchart for explaining the unlocking process. When called from the control means 10 of the portable terminal 1 in a state where the portable terminal 1 is set to the locked state, the unlocking means 14 of the portable terminal 1 is activated, and the unlocking means 14 uses authentication data used for user authentication. Is displayed on the display, and authentication data is obtained from the user (S20).

  When the authentication data is a password or PIN, the authentication data is input to the mobile terminal 1 through the operation panel. When the authentication data is fingerprint data, the authentication data is input into the mobile terminal 1 through a fingerprint sensor not shown in FIG. .

  When the lock release unit 14 of the mobile terminal 1 acquires authentication data from the user, the authentication data is collated with the data stored in the memory 1d of the mobile terminal 1 to authenticate the user who operates the mobile terminal 1 as a user authentication. (S21).

  If the user terminal authentication is successful, the unlocking means 14 of the portable terminal 1 releases the locked state of the portable terminal 1 (S22) and ends this procedure. If the user authentication fails, this procedure is terminated without releasing the lock state of the mobile terminal 1.

  Next, the action range setting unit 16 of the mobile terminal 1 will be described. First, the operation of the action range setting unit 16 in the additional range setting process executed after the lock release process will be described. FIG. 8 is a flowchart for explaining the additional range setting process.

  In the unlocking process, when the unlocking means 14 of the mobile terminal 1 unlocks the mobile terminal 1, the action range setting means 16 of the mobile terminal 1 instructs the position measuring means 11 to measure the position information, When the measuring means 11 measures the position information (S30), the position information measured by the position measuring means 11 is transferred to the speed measuring means 12, and the speed measuring means 12 is made to measure the speed information (S31).

  When the speed measuring means 12 measures the speed information, the action range setting means 16 of the mobile terminal 1 checks whether the position information measured by the position measuring means 11 is included in the action range 17 stored in the memory 1d (S32). ).

  When the position information measured by the position measuring unit 11 is included in the action range stored in the memory 1d, the action range setting unit 16 of the mobile terminal 1 performs this procedure without setting the additional range as the action range 17. finish.

  When the position information measured by the position measuring unit 11 is not included in the action range 17 stored in the memory 1d, the action range setting unit 16 of the mobile terminal 1 sets the size of the additional range to be added to the action range 17. Determine (S33).

  The size of the additional range to be added to the action range 17 may be fixed, but since the user's moving means can be known from the speed information of the mobile terminal 1, in the present embodiment, an inverse correlation is obtained with respect to the speed information measured by the speed measuring means 12. Determine the size of the additional range.

  For example, when the speed information measured by the speed measuring means 12 is fast, it can be assumed that the user is on a vehicle such as a car, and when the user is using a vehicle, the user cannot move off the road or track. When the size of the additional range is reduced and the moving speed is slow, it can be assumed that the user is walking, and when the user is walking, the additional range is increased because the user can move arbitrarily.

  When the size of the additional range to be added to the behavior range 17 is determined, the behavior range setting unit 16 of the mobile terminal 1 adds the determined additional size range to the behavior range 17 centering on the position information measured by the position measurement unit 11. (S34), and this procedure is finished.

  FIG. 9 is a diagram for explaining the content that the additional range is added to the action range 17. The circles illustrated in FIG. 9A indicate the additional range 17a added to the action range 17 when the mobile terminal 1 is unlocked, and the action range when the mobile terminal 1 is released from the locked state. An additional range 17a is added to 17 and updated so that the default action range 17 illustrated in FIG. 4A is expanded as illustrated in FIG. 9B.

  Next, the operation of the action range setting unit 16 in the default action range setting process will be described. When the action range setting means 16 provided in the mobile terminal 1 is called from the control means 10 of the mobile terminal 1 in a state where the action range is not stored in the memory 1d of the mobile terminal 1, it is within a certain period (for example, one week). ), The position information of the portable terminal 1 is periodically acquired while the locked state of the portable terminal 1 is released, and the additional action range centered on the position information of the portable terminal 1 is combined to obtain a default action range. The process which sets 17 to the portable terminal 1 is performed.

  Next, the behavior analysis means 15 of the mobile terminal 1 will be described. The behavior analysis means 15 provided in the mobile terminal 1 is called from the control means 10 of the mobile terminal 1 when a preset date and time condition is satisfied, and is stored in the memory 1d of the mobile terminal 1 according to a predetermined method. This is means for analyzing the distribution of position information and deleting from the action range 17 a range where the distribution density of the position information is low.

  Here, the date and time condition is a condition for specifying a date and time, and a date and time or a day of the week and time are specified as a date and time condition. Since a certain amount of time is required to analyze the position information stored in the mobile terminal 1, a date and time when the user does not use the mobile terminal 1 (for example, 3 am on Monday) may be set as the date and time condition. In addition, a behavior analysis method can be used as a method of analyzing a distribution of position information stored in the mobile terminal 1 and specifying a range where the distribution density of the position information is low. As such a behavior analysis method, a kernel method or the like can be used. It is famous.

  FIG. 10 is a flowchart for explaining the behavior analysis process.

  When a predetermined date and time condition is satisfied, the behavior analysis unit 15 is activated by being called from the control unit 10 of the portable terminal 1, and the behavior analysis unit 15 of the portable terminal 1 uses a predetermined method to store the memory of the portable terminal 1. The distribution of the position information stored in 1d is analyzed, and the range where the user's usage frequency is equal to or less than the threshold is specified as the deletion range (S40).

  For example, when analyzing the distribution of position information using the kernel method, the range that may contain 95% of the position information is “95% home range” and may contain 50% of the position information. A range may be obtained as “50% home range” or the like, and an area not included in “95% home range” may be specified as a deletion range.

  When the deletion range is specified, the behavior analysis unit 15 of the mobile terminal 1 updates the behavior range 17 by deleting the deletion range from the behavior range 17 (S41), and then stores the position information stored in the memory 1d of the mobile phone. Is deleted (S42), and this procedure is terminated.

  FIG. 11 is a diagram for explaining the contents to be deleted from the action range 17. The right diagram of FIG. 11A shows the position information in the dotted line part of the left diagram of FIG. 11A, and the ellipse shown in the right diagram of FIG. It becomes the range 17b.

  FIG. 11B illustrates the action range 17 after the deletion range is deleted, and the deletion range 17 b obtained by analyzing the distribution of position information stored in the mobile terminal 1 is deleted from the action range 17. Thus, as illustrated in FIG. 11B, the action range 17 illustrated in FIG. 11A is updated so as to be reduced.
