Description

  The present invention relates to a portable communication terminal device having an anti-theft function that locks an operation unit in conjunction with position information by GPS (Global Positioning System) or the like, an anti-theft method for portable communication terminal device, and the theft of portable communication terminal device Prevention program.

  Since mobile communication terminal devices represented by mobile phones contain personal information and company information of communication partners, there is an increasing number of cases where such information is abused and serious damage is caused when it is stolen.

  In order to solve such problems, there is a method of using a key operation lock function. In this method, the key operation is unlocked only when a password is input (Patent Document 1). Further, when the position information is periodically obtained using GPS and used at a position away from the predetermined position by a predetermined distance, if the input of the password is failed more than the specified number of times, the lost notification mail is sent to the predetermined communication destination terminal. Send to.

  In addition, the location where the mobile communication terminal device can be used is a route selected from the transportation means connecting the current location and the destination, and the position of the mobile communication terminal device obtained by GPS based on the selected route is used. There is one that determines whether or not it is possible (Patent Document 2). If it is determined that the location is unusable, the mobile communication terminal device is not connected to the network server storing the phone book data.

(Embodiment 1)
In the first embodiment, a user often carries a mobile communication terminal device. For example, a route for commuting or school is automatically stored in a storage unit by a self-learning function of the mobile communication terminal device, and mobile communication is performed. When the terminal device is operated at a location more than a predetermined distance from this route, the input by the operation is automatically locked, and the operation by the user is invalidated unless the password set in advance by the user is input.

  A configuration example of the mobile communication terminal device according to the first embodiment is shown in FIG. FIG. 1 shows only the components related to theft prevention which is the object of the present invention, and does not show the components related to the normal communication function. The mobile communication terminal device 1 includes a GPS communication control unit 2, a terminal control unit 4, an operation unit 5, a display unit 6, and a storage unit 7. The GPS communication control unit 2 includes an antenna and the GPS communication device 20, and the terminal control unit 4 includes a GPS signal processing unit 40, a position information control unit 41, a route setting unit 42, a position determination unit 43, and an operation. And a lock control unit 44. The operation lock control unit 44 includes an operation lock unit 45, and the storage unit 7 includes a position information storage unit A 70, a position information storage unit B 71, and a route information storage unit 72.

  The GPS communication device 20 acquires a GPS signal from a GPS satellite as positioning information via an antenna in order to obtain position information of the mobile communication terminal device 1.

  The GPS communication control unit 2 controls the operation of the GPS communication device 20 and outputs the acquired positioning information to the GPS signal processing unit 40 of the terminal control unit 4 together with the acquisition date and time.

  The operation unit 5 is, for example, a key operation unit, and is a part for the user to input various instructions to the mobile communication terminal device 1.

  The display unit 6 is a display screen such as a CRT.

  The storage unit 7 is configured by a memory device such as a hard disk, the position information storage unit A70 stores the position information acquired for route setting, the position information storage unit B71 stores the position information acquired during normal use, and the route information storage unit 72 stores information on a route set based on the position information stored in the position information storage unit A70. Although not shown, the storage unit 7 also stores a program for operating the terminal control unit 4.

  The terminal control unit 4 includes a CPU (Central Processing Unit) and a RAM (Random Access Memory), a ROM (Read Only Memory), and the like used for processing by the CPU. 1, and controls the GPS signal processing unit 40, the position information control unit 41, the route setting unit 42, the position determination unit 43, and the operation lock control unit 44 to realize the anti-theft function. The terminal control unit 4 implements the functions of each unit by reading and executing the program stored in the storage unit 7.

  The position information control unit 41 controls the GPS communication control unit 2 and the GPS signal processing unit 40 so as to acquire the position information at a predetermined cycle, and stores the obtained position information in the storage unit 7. The position information acquired at the time of route setting is stored in the position information storage unit A70, and the position information acquired at the time of normal use is stored in the position information storage unit B71. The time when the route is set is the time between when the user first turns on the power as the route setting start date and time, and when the predetermined time Te has passed since that time as the route setting end date and time. The position information control unit 41 issues a route setting instruction to the route setting unit 42 at the end of route setting.

  The GPS communication control unit 2 and the GPS signal processing unit 40 constitute a position information acquisition unit 3. The position information acquisition unit 3 acquires the position information of the mobile communication terminal device 1 at a predetermined cycle (positioning cycle) according to the control of the position information control unit 41.

  The route setting unit 42 reads the position information stored in the position information storage unit A 70 based on an instruction from the position information control unit 41, creates a route, and stores the created route in the route information storage unit 72 as route information. To do. For example, each point of position information stored in time series is connected by a straight line in order to make a path, or each point of position information in a predetermined range is approximated by a curve, and an approximate curve and its definition range are taken as a path, etc. A route is set by the method.

  The position determination unit 43 receives an instruction from the operation lock control unit 44 described later, and stores the latest position information (referred to as the current position) of the mobile communication terminal device 1 stored in the position information storage unit A70 and the route information. The route stored in the unit 72 is read out. When the current position is within a predetermined distance from the route, it is determined that the route is on the route. When the current position is more than the predetermined distance, it is determined that the route is not on the route. The determination result is output to the operation lock control unit 44.

  When receiving an input from the operation unit 5, the operation lock control unit 44 instructs the position determination unit 43 to perform the above determination on the current position, and inputs the determination result. If the determination result is that the current position is not on the route, the operation lock control unit 44 outputs a display requesting the input of the password to the display unit 6, and the operation unit 5 via the operation lock unit 45. Lock other inputs from.

  When the password entered via the operation unit 5 matches the password set in advance, the operation lock control unit 44 releases the lock via the operation lock unit 45. If the input password does not match the password set in advance a predetermined number of times, the operation lock control unit 44 continues to lock all inputs via the operation unit 5. Therefore, thereafter, the mobile communication terminal device 1 cannot be used.

  If the determination result indicates that the current position is on the route, the operation lock control unit 44 releases the lock via the operation lock unit 45. Therefore, the subsequent use of the mobile communication terminal device 1 becomes possible.

  An operation of the mobile communication terminal device 1 according to the present embodiment will be described. The user issues an instruction to turn on the power from the operation unit 5 and starts using the mobile communication terminal device 1. At this time, the mobile communication terminal device 1 automatically performs route setting as follows over a predetermined time Te from when the power is first turned on.

  A signal for instructing to turn on the power is input to the position information control unit 41. Accordingly, the position information control unit 41 causes the position information acquisition unit 3 to acquire position information at a predetermined positioning cycle, and stores the acquired position information in the position information storage unit A70 or B71. When the signal for instructing to turn on the power is received for the first time, the path information is set as time series information in the position information storage unit A70 until the predetermined time Te elapses from the time when the signal is received. To do. When the route is not set, the location information is stored in the location information storage unit B71. The position information stored in the position information storage unit B71 only needs to have at least one latest position information. For example, the previously acquired position information is updated with the latest position information.

  FIG. 2 shows an example of position information stored in the position information storage unit A70. x (i) and y (i) are X and Y coordinate values of the position of the mobile communication terminal device 1 represented by L (i) (i = 1 to n), respectively. Each position is acquired at a predetermined positioning cycle and arranged in time series.

  The position information control unit 41 issues a route setting instruction to the route setting unit 42 when a predetermined time Te has elapsed during route setting. In response to this instruction, the route setting unit 42 reads the position information stored in the position information storage unit A 70, sets a route from the read position information, and stores it in the route information storage unit 72 as route information.

  FIG. 3 is an example in which, for example, a route set based on the position information of FIG. 2 is illustrated on the X and Y planes. The route shown here is an example in which each position of the position information is connected in a straight line in order. Black circles indicate each position of the position information. Assuming that the commuting route from home to the office is set as a route, the user turns on the power for the first time through the operation unit 5 when leaving the home, and a predetermined time Te has passed when the user arrives at the company. Yes. Commuters use walking, buses and trains. Since the position information is acquired at a predetermined positioning cycle, the interval between the black circles differs depending on the walking speed, the traveling speed of the bus, and the traveling speed of the train.

  The route information in this case is the same as the position information shown in FIG. 2 on the premise that the points where the position information is obtained are connected by straight lines. In such a case, the position information storage unit A 70 and the route information storage unit 72 can be shared, and the route setting unit 42 is absorbed by the position information control unit 41.

  Note that, from the start to the end of the route setting, the corresponding position information may be acquired a plurality of times including the round trip for the target route such as a commuting route. Also in this case, it is possible to create a route by connecting the position information arranged in time series as it is with a straight line, or using an approximate curve group. The route in this case can be said to be a route created by connecting position information in a single stroke.

  The operation of the mobile communication terminal device 1 after the route information is set in this way will be described. Also at this time, the position information acquisition unit 3 acquires the position information at a predetermined positioning cycle under the control of the position information control unit 41, as in the route setting. The positioning cycle at this time may be a value different from the positioning cycle at the time of route setting. The position information control unit 41 stores the position information acquired by the position information acquisition unit 3 in the position information storage unit B71. This position information only needs to include at least the latest position information.

  When the user operates the operation unit 5 to input some instruction, this input signal is input to the operation lock control unit 44. In response to this input, the operation lock control unit 44 instructs the position determination unit 43 to make a determination. Upon receiving the instruction, the position determination unit 43 reads the latest position information from the position information storage unit B71 and sets this as the current position. Further, the route information stored from the route information storage unit 72 is read out, whether or not the current position is on the read route is determined, and the determination result is notified to the operation lock control unit 44. In the case of the determination result that the current position is not on the route, the operation lock control unit 44 instructs the operation lock unit 45 to lock the input from the operation unit 5 except for the input of the following password, and the display unit A display prompting the user to input a password is displayed at 6. When the user inputs a personal identification number, the operation lock control unit 44 determines whether the personal identification number matches a personal identification number registered in advance. If it does not match, it asks again for the code number, and if it is determined that the numbers do not match a predetermined number of times, the operation lock unit 45 is instructed to include the input from the operation unit 5 including the code number input. Lock completely. When it is determined that the current position is on the route, and when it is determined that the input security code matches the registered security code, the operation lock control unit 44 instructs the operation lock unit 45 to perform the operation. The input from the unit 5 is unlocked.

  The fact that the current position is on the route means that the shortest distance between the current position and the route is smaller than a predetermined criterion distance. If the predetermined condition is satisfied, in order to simplify the determination, instead of this determination, the distance between the position closest to the current position and the current position is the position information constituting the route. You may determine based on whether it is below the distance of a criterion. The predetermined condition is a case where the distance serving as the determination criterion is sufficiently larger than the distance between adjacent points of the position information that constitutes the route. A path when this condition is satisfied is sufficient for each point having position information constituting the path, and it is not necessary to define whether or not each point is a straight line. Whether or not to make a simplified determination is determined in advance by the user or the like in consideration of the above conditions.

  The route setting method and theft prevention method of the mobile communication terminal device 1 according to the first embodiment will be described based on the flowcharts of FIGS. 4 and 5. First, a route setting method will be described. FIG. 4 is a flowchart showing the route setting method A according to the first embodiment. The position information control unit 41 that has received a signal for instructing power ON for the first time starts measuring the elapsed time Tt related to the route setting time (step S1) and starts measuring the elapsed time T related to the control in the positioning cycle. (Step S2). Next, the position information control unit 41 acquires information on the current position via the position information acquisition unit 3, and stores the acquired position information in the position information storage unit A70 (step S3).

  Next, the position information control unit 41 determines whether or not the elapsed time T is longer than the positioning cycle (step S4). When it is determined that the elapsed time T is less than the positioning cycle (step S4; NO), the position information control unit 41 repeats step S4 until the elapsed time T becomes equal to or longer than the positioning cycle. If it is determined that the elapsed time T is greater than or equal to the positioning cycle (step S4; YES), it is determined whether the elapsed time Tt is greater than the predetermined time Te (step S5).

  When it is determined that the elapsed time Tt is equal to or less than the predetermined time Te (step S5; NO), step S2 and subsequent steps are repeated. When it is determined that the elapsed time Tt is greater than the predetermined time Te (step S5; YES), the position information control unit 41 instructs the route setting unit 42 to set a route. Upon receiving the instruction, the route setting unit 42 reads the position information stored in the position information storage unit A70, creates a route based on the position information, and stores the route information in the route information storage unit 72 (step S6). ), The route setting ends.

  FIG. 5 is a flowchart showing the anti-theft method A for the mobile communication terminal device 1 using the route information set as described above. The position information control unit 41 starts measuring the elapsed time T in order to manage the positioning cycle (step S10), acquires the current position information at a predetermined positioning cycle via the position information acquisition unit 3, and stores the position information. Store in part A70 (step S11). The positioning cycle at this time may be set in advance to a value different from that at the time of route setting.

  On the other hand, the operation lock control unit 44 determines whether or not an input has been made via the operation unit 5 (step S12). When it is determined that there is an operation input (step S12; YES), the operation lock control unit 44 instructs the position determination unit 43 to store the latest position information (current position) stored in the position information storage unit B71. Then, it is determined whether or not the route is stored in the route information storage unit 72 (step 13), and the determination result is acquired. When the determination result obtained from the position determination unit 43 is not located on the route (step S13; NO), the operation lock control unit 44 displays a display requesting the input of the password on the display unit 6 and the operation lock unit. The input from the operation unit 5 other than the input of the personal identification number is locked via 45 (step S14).

  Next, the operation lock control unit 44 determines whether or not the input personal identification number matches a personal identification number registered in advance (step S15). When it is determined that the predetermined number of times does not match (step S15; NO), the operation lock control unit 44 maintains the lock of the input from the operation unit 5 including the input of the personal identification number. If the input security code matches the registered security code (step S15; YES), the operation lock control unit 44 releases the lock via the operation lock unit 45 and proceeds to step S17 described below. (Step S16).

  When it is determined in step S12 that there is no operation input (step S12; NO) and when it is determined that the current position is located on the route (step S13; YES), the operation lock control unit 44 receives the position information. The control unit 41 is notified accordingly. The position information control unit 41 that has received the notification determines whether or not the elapsed time T is equal to or greater than the positioning cycle (step S17). When the elapsed time T is equal to or longer than the positioning cycle (step S17; YES), the process returns to step S10 in order to acquire position information. When the elapsed time T is less than the positioning cycle (step S17; NO), the position information control unit 41 repeats the determination in step 17 until the elapsed time T becomes equal to or longer than the positioning cycle.

  As described above, according to the first embodiment, the route used for the prevention of theft is based on the position information that the mobile communication terminal device 1 acquires at a predetermined positioning cycle from the first power-on input to the elapse of a predetermined time. Set automatically. Therefore, route setting is easy, and it is possible to set a route regardless of whether or not a transportation facility exists on the route. Further, the data necessary for route setting is only position information along a target route such as a commuting route, and a route is selected and set from several options as described in Patent Document 2. Therefore, it is possible to save the trouble of preparing a large amount of information in advance and to save the storage capacity.

  In addition, since the use position of the mobile communication terminal device 1 is determined to be likely to be stolen only when it is more than a predetermined distance from the route set as described above, the password is requested to be entered. You will not be asked to enter your PIN every time. Therefore, the portable communication terminal device is easy for the user to use.

  Even if the password is required to be entered every time it is used, according to the present embodiment, if the current position is not on the route, a password different from the normally used password is set. Can be set to input. This measure can further strengthen the anti-theft function. The different password at this time may be a password that is completely different from the normally set password, but in order to prevent an input error, for example, the normally set password is repeated to double the number of digits. You may take measures such as changing your PIN.

  In the example illustrated in FIG. 1, the route setting unit 42 is independent from the position information control unit 41, but the function of the route setting unit 42 may be included in the position information control unit 41.

  Moreover, although what used a GPS signal was illustrated as the positional information acquisition part 3, it does not need to be limited to this. The position information may be acquired by signals from a plurality of stations, or any other positioning means.

  Furthermore, when only the latest position information is stored in the position information storage unit B71, the position information may be temporarily stored in a memory such as a RAM of the terminal control unit 4 instead of the position information storage unit B71. . At this time, the position determination unit 43 does not read the current position from the position information storage unit B71, but reads it from a memory such as a RAM of the terminal control unit 4.

  Further, the lock setting in step S14 of FIG. 5 may be brought after the determination in step S15 is “NO”. In that case, the unlocking in step S16 arranged after the determination in step S15 is “YES” is deleted.

  As a modification, the route setting unit 42 rearranges the position information in the order of the adjacent points in the spatial arrangement based on the time-series position information acquired a plurality of times for the target commuting route, for example. A route may be set by connecting the arranged positions with a straight line or an approximate curve. An example is shown in FIG. As in FIG. 3, FIG. 6 (a) connects each point with a straight line in chronological order based on the position information acquired at a predetermined cycle along the outbound route of the target route such as a commuting route. It is an example when a route is set. The point where the position information is obtained is indicated by a black circle. As can be seen in this example, the route between the points where the position information before and after the corner is obtained (solid line in the figure) is considerably different from the actual route (dashed line in the figure). In order to improve this, position information is acquired at a predetermined cycle along the return path, for example, with respect to the same route. The white circle in FIG. 6B corresponds to the position information obtained along the return path. If the route is set by connecting the nearest points in order with a straight line, the same effect as when the position information is acquired with a shorter period can be obtained, for example, the difference between the route at the corner and the actual route is reduced. .

  FIG. 7 shows an example in which a route is created based on position information when a section having a target route is reciprocated 1.5 times. FIG. 7A is an example of position information stored in the position information storage unit B71. Here, L (i) to L (i + 5), L (j) to L (j + 5), and L (k) to L (k + 5) correspond to the section with the target route, the forward path, the return path, Time-series position information obtained along the forward path.

  The route setting unit 42 rearranges the data in the spatial arrangement order of the points based on the position information. FIG. 7B shows an example of rearrangement, and FIG. 8 shows this on the X and Y planes. In FIG. 8, L (i) to L (i + 5) are black circle marks, L (j) to L (j + 5) are black square marks, and L (k) to L (k + 5) are black triangle marks. A path is formed by connecting adjacent points with a straight line. Assuming this linear connection, the route information in this case is the same as the position information after rearrangement shown in FIG. As can be seen from FIG. 8, a path is set by connecting lines L (i) to L (i + 5), L (j) to L (j + 5), and L (k) to L (k + 5) in chronological order. Rather than doing this, it is better to re-arrange the points using all the position information and set the route, so the position information is acquired in a substantially shorter cycle, and the difference between the set route and the actual route is Improved.

(Embodiment 2)
In the second embodiment, it is possible to set a route at any time while assuming automatic route setting. The configuration of the mobile communication terminal device 1 of the present embodiment is the same as that of FIG. The present embodiment is different from the first embodiment in that route setting start and end instructions are input from the operation unit 5. These input signals are input to the position information control unit 41, and the start and end of position information acquisition for route setting are determined. During this time, the position information control unit 41 acquires position information via the position information acquisition unit 3 and stores it in the position information storage unit A70. Further, when an instruction to end the route setting is input, the position information control unit 41 instructs the route setting unit 42 to set the route. In response to this instruction, the route setting unit 42 creates a route based on the position information stored in the position information storage unit A 70 and stores the route in the route information storage unit 72. According to this method, a plurality of routes can be set. When setting a plurality of routes, the route information stored in the route information storage unit 72 has a route number attached to identify the plurality of routes. An example is shown in FIG.

  The operation of the mobile communication terminal device 1 according to the second embodiment is basically the same as that of the first embodiment, but the route setting is started by inputting a route setting start instruction from the operation unit 5 and used for route setting. The position information is different from the input of the path setting start instruction until the path setting end instruction is input. Therefore, unlike the first embodiment in which the route setting is performed only once at the beginning, the route setting is performed whenever a route setting start instruction is input.

  In the second embodiment, the route setting can be started any time when an instruction to start the route setting is input during use of the mobile communication terminal device 1. Therefore, unlike the first embodiment, the route setting method and the anti-theft method cannot be completely separated, and the route setting method constitutes a part of the anti-theft method. Below, the anti-theft method B of the mobile communication terminal device 1 according to the second embodiment will be described first, and then the route setting method B will be described.

  FIG. 10 is a flowchart showing a theft prevention method B of the mobile communication terminal device 1 according to the second embodiment. The anti-theft method 2 is partially modified based on FIG. 5 showing the anti-theft method A according to the first embodiment. Steps denoted by the same reference numerals are the same as the contents of FIG.

  FIG. 10 differs from FIG. 5 in that at the beginning of the processing, that is, before the step S10 and while waiting until the elapsed time T exceeds the positioning cycle, that is, when the determination result in the step S17 is “NO”, respectively. Steps S20 and S22 for determining whether or not there has been an instruction to start route setting are inserted. If there is no instruction, the same processing as in FIG. 5 is performed, and if there is an instruction, steps S21 and S23 for executing the route setting processing are performed. And that the return destination when the determination result in step S17 is “YES” is not step S10 but step S20.

  By correcting in this way, in the process of the anti-theft method B, first, it is determined by the position information control unit 41 whether there is an instruction to start route setting (step S20). If it is determined that there is no instruction, that is, there is no input of a route setting start instruction from the operation unit 5 (step S20; NO), the process proceeds to step S10 and subsequent steps as in the process of FIG. On the other hand, if it is determined that there is a route setting instruction (step S20; YES), a route setting process (step S21) is executed. This route setting process will be described later.

  When it is determined in step S17 that the elapsed time T is not equal to or longer than the positioning cycle (step S17; NO), the position information control unit 41 repeats the determination in step S17 until the elapsed time T becomes equal to or longer than the positioning cycle. While waiting for the elapse of time, the presence / absence of a route setting start instruction is determined each time during this time (step S22). If it is determined that there is no instruction to start route setting (step S22; NO), the position information control unit 41 proceeds to the determination of step S17 each time as in FIG. 5, and if it is determined that there is an instruction to start route setting. (Step S22; YES), the process proceeds to the route setting process (Step S23).

  As described above, during the theft prevention process, the position information control unit 41 always monitors whether there is an instruction to start route setting. If there is an instruction to start route setting, the position information control unit 41 proceeds to route setting processing (processing shown in the route setting method shown in FIG. 11). When the route setting process is completed, the process returns to the normal anti-theft process (after step S10) shown in FIG.

  When inputting a route setting start instruction, the route may not be set or the current position may or may not be on the previously set route. For this reason, it is desirable to input the personal identification number unconditionally without performing the usual anti-theft processing for the input of the route setting start instruction. Therefore, the anti-theft processing related to the input lock is not performed for the input of the route setting start instruction in steps S20 and S22 unlike the normal operation in step S12. The password input process is included in the next route setting method.

  A route setting method will be described. FIG. 11 is a flowchart showing the route setting method B of the mobile communication terminal device 1 according to the second embodiment. This processing is a diagram for explaining the processing content of step S21 or step S23 shown in FIG. 10, and when the processing is completed, the processing is returned to step S10 of FIG. 10 in principle. The route setting method B is partially modified based on FIG. 4 for explaining the route setting method A according to the first embodiment. Steps denoted by the same reference numerals are the same as the contents of FIG.

  FIG. 11 differs from FIG. 4 in that step S30 for determining whether or not the input PIN number is coincident with the registered PIN number is first requested, and that there is a mismatch in step S30. At the time of determination, step S32 for locking the input from the operation unit 5 is added to end the process, and the total elapsed time Tt is measured to recognize the end of the route setting in FIG. Deleting step S1 to be started and step S5 for determining whether or not the total elapsed time Tt has exceeded a predetermined time Te set in advance to determine the final acquisition date and time of the position information to be route-set; Instead of step S5, step S31 for determining whether or not there is an instruction to end the route setting is inserted.

  If it is determined in step S30 that the entered password matches the registered password (step S30; YES), the route setting process is stolen until a route setting end instruction is input. The prevention process (the part corresponding to steps S13 to S16 in FIG. 10) is not allowed to function, and the process proceeds to step S2. When it is determined that the input code number does not match the registered code number a predetermined number of times (step S30; NO), it is assumed that there is a high risk of theft and not only the route setting but also the operation of the mobile communication terminal device 1 itself. Is locked (step S32).

  Steps S2 to S4 are the same as in FIG. If the elapsed time T is equal to or longer than the positioning cycle (step S4; YES), the position information control unit 41 determines whether or not there is an instruction to end the route setting (step S31). If there is no end instruction (step S31; NO), the process returns to step S2 and the following processing is repeated. If there is an instruction to end (step S31; YES), the path creation / storage process is executed as in the case of FIG. 4 (step S6), and the process returns to step S10 of the anti-theft method B. The position information is acquired from a route setting start instruction to a route setting end instruction, and a route is set based on the position information obtained during that time.

  According to the present embodiment, a route can be set by inputting a route setting start / end instruction for each target route as necessary. FIG. 12 shows a schematic diagram of the route set as a result. In FIG. 12, a plurality of paths are radially set around the position A and the position B. Further, the path from the position A to the position F, such as the paths 4 and 5, can be divided at the position E and divided into two paths. The same applies to the paths 6 and 7. Furthermore, an independent route that is not connected to another route such as the route 11 can be set. Thus, according to the present embodiment, a route can be added and set at any time with a simple operation. Further, since the degree of freedom of route setting increases, only the route to be set can be selected and set.

  When multiple routes are set for a specific section of the target route, each set of position information acquired at the time of setting each route is treated as independent, and a route is set for each set of position information. Is set. However, if the target section is specified and each position information can be recognized as position information for a common section, each position is spatially rearranged from the entire set of position information. Route information can be created. The effect at this time is that the difference between the created route and the actual route is reduced because the period for acquiring the position information is substantially shortened as already described in the first embodiment.

(Embodiment 3)
In the third embodiment, the positioning cycle at the time of route setting is set independently of the positioning cycle at the time of normal use. The configuration of the mobile communication terminal device 1 is the same as that shown in FIG. The positioning cycle at the time of setting the route is set by inputting the positioning cycle Tm via the operation unit 5. After shifting to the route setting process in response to the route setting start instruction input from the operation unit 5, or the period input from the operation unit 5 simultaneously with the route setting start instruction is input to the position information control unit 41. The position information control unit 41 controls the subsequent acquisition of the position information at the input cycle Tm until an input of a route setting end instruction is received.

  The anti-theft method according to the third embodiment is the same as FIG. 10 showing the anti-theft method B according to the second embodiment. FIG. 13 is a flowchart showing an example of a route setting method C according to the present embodiment. FIG. 13 is a modification based on FIG. The difference from FIG. 11 is that step S40 for setting the positioning cycle Tm is added between step S30 and step S2, and step S4 for determining whether or not the elapsed time T is equal to or longer than the positioning cycle. If it is determined in step S41 that it is determined whether or not the positioning cycle is greater than or equal to the positioning cycle Tm, and if it is determined in step S31 that a route setting end instruction has been received (step S31; YES), the positioning cycle is returned to the original value. Step S42 is added.

  After the passwords match (step S30; YES), the positioning cycle related to the position information acquisition in the route setting process is changed to Tm (step S40), and steps S2 and S3 are performed as in FIG. If the elapsed time T is less than the positioning cycle Tm (step S41; NO), wait until the elapsed time T becomes equal to or longer than the positioning cycle Tm (step S41; YES). Whether or not there is is determined (step S31). If there is an instruction to end the route setting (step S31; YES), the positioning cycle Tm is returned to the original positioning cycle (step S42). Therefore, the positioning cycle is Tm from the setting start to the end. Other processes are the same as those in FIG.

  According to the third embodiment, since the positioning cycle at the time of route setting can be freely set independently of the positioning cycle at the time of normal use, the positioning cycle at the time of route setting is determined from the positioning cycle at the time of normal use according to the situation. By reducing the distance, it is possible to further reduce the difference between the path that is actually taken and the set path while suppressing the load required to acquire position information during normal use.

  When a plurality of routes are set, the positioning cycle can be changed for each route. For example, a route can be set for each means of transportation used at the time of route acquisition, and the positioning cycle can be changed according to the means of transportation. An example of the route set in this way is shown as a schematic diagram in FIG. In FIG. 14, the route is set for each means of transportation. The size of the positioning cycle when using each means of transportation is in the order of walking> bus riding> train riding. Thus, ideally, the distance between the positions forming the route can be made substantially the same for each means of transportation. The difference between the route set in this way and the path that actually passes can be reduced, and the load on the terminal control unit 4 related to position information acquisition can be reduced as compared with the case where the acquisition cycle is uniformly shortened. Can do. As a result, the battery life is improved, and the provision of services is improved because there is room for other services.

  In order to further reduce the load of position information acquisition, it is preferable to pass the same route a plurality of times as described in the first and second embodiments, and set a route based on the position information acquired at that time. Since a longer cycle can be set compared to the case where a route is set once, the load of acquiring position information is further reduced.

  The route setting by the route setting unit 42 according to the present invention is not limited to the configuration and method described in the first to third embodiments. Any configuration and method for automatically setting a route based on position information acquired by the mobile communication terminal device 1 may be used.

  The mobile communication terminal device 1 can be considered as a computer in a broad sense. Therefore, the flowcharts shown in FIGS. 4, 5, 10, 11, and 13 described in the first to third embodiments also show the contents of the anti-theft program including the route setting of the mobile communication terminal device 1.
