  FIG. 3 is a diagram illustrating an example of an operation flow of setting processing of the mobile terminal 2 by the central processing unit 220. The operation flow described below is executed mainly by the central processing unit 220 in cooperation with each element of the mobile terminal 2 based on a program stored in the storage unit 210 in advance.

  First, the setting reception unit 221 waits until receiving a setting notification for notifying that there is a setting request to the mobile terminal 2 from the SMS transmission server 6 via the first wireless communication unit 201 (step S101). .

  As will be described later, the management terminal 3 can set the mobile terminal 2. When setting the mobile terminal 2, the management terminal 3 transmits a setting request for the mobile terminal 2 to the management server 4. When receiving a setting request from the management terminal 3 to the portable terminal 2, the management server 4 generates a setting notification and transmits it to the SMS generation server 5. The SMS generation server 5 transmits the received setting notification to the SMS transmission server 6 as an e-mail according to the SMTP protocol, and the SMS transmission server 6 transmits the received setting notification to the portable terminal 2 as an SMS message.

The setting function is a function in which specific items are set by the management terminal 3, such as “edit phone book” and “status monitoring setting”. The setting item is an item set by the management terminal 3 for the setting function. When the setting function is “edit phone book”, the setting items are the contact, name, phonetic, phone number, mail address, and the like to be edited. When the setting function is “status monitoring setting”, the setting item is whether or not the status monitoring is turned ON. The URL indicates the address of the management server 4 and the folder name and file name in which each setting item designated by the management terminal 3 is stored.

  Next, when the setting reception unit 221 receives a setting notification from the SMS transmission server 6 via the first wireless communication unit 201 (step S101—Yes), the setting reception unit 221 sets the setting to the management server 4 via the first wireless communication unit 201. A setting acquisition request for requesting acquisition of an item is transmitted. And the setting reception part 221 acquires a setting item by receiving the setting acquisition response which is a response with respect to a setting acquisition request from the management server 4 via the 1st wireless communication part 201 (step S102).

  The setting reception unit 221 acquires a setting item by accessing a URL included in the setting notification according to, for example, an HTTP (Hypertext Transfer Protocol) protocol.

  Next, the setting reception unit 221 sets the acquired setting item for the setting function included in the setting notification (step S103), and ends a series of steps.

  For example, when the setting function is “edit phone book”, the setting reception unit 221 stores the name, phonetic, phone number, and mail address of the contact specified in the setting item in the phone book stored in the storage unit 210. Etc. are set. In addition, when the setting function is “status monitoring setting”, the setting reception unit 221 sets the status monitoring flag stored in the storage unit 210 according to whether or not the setting item specifies that status monitoring is to be turned ON. To do.

  As described above, the management server 4 transmits the setting notification as an SMS message to the mobile terminal 2 via the SMS generation server 5 and the SMS transmission server 6, so that the HTTP server function or the like is not implemented in the mobile terminal 2. The mobile terminal 2 can be notified in real time that the setting request has been received from the management terminal 3. Further, the portable terminal 2 can acquire a large-capacity setting item that is difficult to transmit with an SMS message by acquiring the setting item from the management server 4 according to the HTTP protocol. The above function can be realized if the management server 4 has an HTTP server function, and it is not necessary to mount an HTTP server function or the like on the mobile terminal 2, so that the development scale of the mobile terminal 2 is not increased. be able to.

  FIG. 4 is a diagram illustrating an example of an operation flow of route guidance processing by the central processing unit 220. The operation flow described below is executed mainly by the central processing unit 220 in cooperation with each element of the mobile terminal 2 based on a program stored in the storage unit 210 in advance.

  Next, when the “start in map mode” button 602 is tapped by the user via the operation unit 203 (step S208—No), the control unit 223 executes route guidance in the map mode and displays the map mode screen. The information is displayed on the display unit 204 (step S209).

  The control unit 223 periodically acquires position information from the GPS unit 209 and sets the position indicated by the acquired position information as the current position. For example, the control unit 223 calculates the distance for each route between the current position and the destination, and determines the route with the shortest distance as the route to the destination. The control unit 223 generates the current position, the destination, the determined route, the distance, and the like as route guidance information.

  FIG. 6B shows an example of the map mode screen. As shown in FIG. 6B, the map mode screen 610 displays an image in which route guidance information is displayed on a map stored in the storage unit 210. The map mode screen 610 displays the current position 611, the destination 612, the route 613 between the current position and the destination, the distance 614 to the destination, and the like as route guidance information. Further, a “set to AR mode” button 615 is displayed on the map mode screen 610.

  On the other hand, when the “start in AR mode” button 601 is tapped by the user via the operation unit 203 (step S208—Yes), the control unit 223 performs route guidance in the AR mode and displays the AR mode screen. The information is displayed on the unit 204 (step S210).

  In the AR mode, the control unit 223 determines the route to the destination in the same manner as in the map mode, and generates the current position, the destination, the determined route, the distance, and the like as route guidance information. In addition, when the road has a branch on the determined route, the control unit 223 indicates the distance to each branch point and the direction in which the user should make a right turn, left turn, or straight travel at each branch point. Information and the like are also generated as route guidance information.

  Furthermore, the control unit 223 determines the orientation of the mobile terminal 2 based on the orientation of the orientation of the mobile terminal 2 output from the geomagnetic sensor 208, and according to the orientation of the mobile terminal 2 on the image captured by the imaging unit 206. Predetermined route guidance information is displayed at a predetermined position. The control unit 223 may detect roads, intersections, and the like from images captured by the imaging unit 206 using a known image processing technique, and display predetermined route guidance information at each detected position.

  In addition, when the user needs to change direction such as right turn or left turn at each branch point, the control unit 223 causes the audio output unit 205 to output a voice instructing the direction change, or generates vibration (not shown). A direction change instruction is notified to the user by vibrating the part in a predetermined pattern.

  FIG. 6C shows an example of the AR mode screen. As shown in FIG. 6C, the AR mode screen 620 displays an image in which route guidance information is displayed on the image captured by the imaging unit 206. The AR mode screen 620 displays a distance 621 to the destination, a distance 622 to the branch point, traveling direction information 623, and the like as route guidance information. Further, on the AR mode screen 620, a “map mode” button 624 is displayed.

  The control unit 223 continues to perform route guidance in steps S211 to S215.

  When executing the route guidance in step S210 or S211, the control unit 223 determines whether or not a mode change is instructed by the user via the operation unit 203 (step S211). The control unit 223 changes the mode depending on whether the “AR mode” button 615 is tapped on the map mode screen 610 or the “Map mode” button 624 is tapped on the AR mode screen 620. It is determined whether or not an instruction has been given.

  When the mode change is not instructed (No at Step S211), the control unit 223 moves the process to Step S213 without performing any particular process. On the other hand, when the mode change is instructed (step S211—Yes), the control unit 223 changes the route guidance mode to the instructed mode (step S212).

  When the state determination part 222 determines with the portable terminal 2 not moving (step S303 -No), the control part 223 transfers a process to step S309.

  On the other hand, when the state determination unit 222 determines that the mobile terminal 2 is moving (step S303—Yes), the control unit 223 moves the second wireless communication unit 202 within the recent fixed period (for example, 1 second). The BSSID included in the beacon received from the access point via the access point is acquired (step S304). Each time the central processing unit 220 receives a beacon via the second wireless communication unit 202, the central processing unit 220 extracts the BSSID from the received beacon and stores it in the storage unit 210 together with the received time. The control unit 223 reads out and acquires the BSSID received within the recent fixed period from the storage unit 210.

  Next, the control unit 223 matches the acquired BSSID with any one of the BSSIDs of the access points stored in the storage unit 210 and prohibited from using the moving route guidance function. It is determined whether or not to perform (step S305).

  When the acquired BSSID does not match any of the BSSIDs of the access points arranged in the area where the use of the moving route guidance function is prohibited (No in step S305), the control unit 223 performs the process in step S309. Migrate to

  On the other hand, when the acquired BSSID matches any one of the BSSIDs of the access points arranged in the area where the use of the route guidance function during movement is prohibited (step S305-Yes), The position information output from the GPS unit 209 is acquired (step S306).

  Next, the control unit 223 determines whether or not the position indicated in the acquired position information is a preset position (step S307). The control unit 223 uses a geofencing technique to install a virtual fence on the map, and when the position indicated by the position information is within a specific fence, the position is a preset position. Is determined. By setting the virtual fence in an area where the use of the route guidance function during movement is prohibited, the control unit 223 determines whether the mobile terminal 2 exists in an area where the use of the route guidance function during movement is prohibited. Can be determined with higher accuracy. In particular, when a virtual fence is set as a station platform or the like, the altitude is set in advance along with the latitude and longitude of the station platform so that the control unit 223 determines whether or not the mobile terminal 2 exists at the station platform. Can be determined more accurately.

  Note that the control unit 223 may specify the current position of the mobile terminal 2 using a cell ID (Identifier) received from the base station 8a.

  If the control unit 223 determines that the position indicated by the position information is not a preset position (step S307—No), the process proceeds to step S309.

  On the other hand, when the control unit 223 determines that the position indicated by the position information is a preset position (step S307—Yes), the display unit 204 restricts the display of the route guidance information (step S308). , To end a series of steps.

  The control unit 223 restricts the display unit 204 from displaying the route guidance information as a restriction on the display of the route guidance information. That is, the display restriction means that route guidance information is not displayed on the display unit 204. Note that the control unit 223 may limit the display of the route guidance information so that an image captured by the imaging unit 206 or a map stored in the storage unit 210 is not displayed on the display unit 204.

  Further, the control unit 223 may display a predetermined image superimposed on the route guidance information on the display unit 204 as a restriction on the display of the route guidance information. In this case, the display restriction means that the display unit 204 displays a predetermined image superimposed on the route guidance information. The predetermined image may be any image that covers the route guidance information. For example, an image showing a warning about the use of route guidance while moving, such as “Please stop and check the screen”. A single color image of a predetermined color, an image with a predetermined pattern, and the like. Note that the control unit 223 displays a predetermined image superimposed on the image captured by the imaging unit 206 or the map stored in the storage unit 210 in the display unit 204 as a restriction on the display of the route guidance information. Also good.

  Further, the control unit 223 restricts only the display of the route guidance information in the map mode as the restriction of the display of the route guidance information, and the AR mode in which the user can confirm the surroundings by the image taken by the imaging unit 206. Display of route guidance information at may be permitted. For example, when the route guidance information is displayed in the map mode, the control unit 223 changes the route guidance information to be displayed on an image other than the map. In this case, the display restriction means that when the route guidance information is displayed on the map, the display unit 204 changes the route guidance information to be displayed on an image other than the map. The image other than the map is, for example, an image captured by the imaging unit 206. That is, the control unit 223 forcibly changes to the AR mode when operating in the map mode. In this case, the control unit 223 prohibits the mode change also in step S212 of FIG.

  On the other hand, in step S307, the control unit 223 determines whether or not the display of the route guidance information is restricted (step S307).

  When the display of the route guidance information is not restricted (No at Step S307), the control unit 223 ends the series of steps without performing any particular processing. That is, in this case, the control unit 223 displays the route guidance information on the display unit 204.

  On the other hand, when the display of route guidance information is restricted (step S307-Yes), the control unit 223 releases the restriction of display (step S308), displays the route guidance information on the display unit 204, End the step.

  Note that the processing of steps S304 to S305 and / or S306 to S307 may be omitted. In this case, when the state determination unit 222 determines that the mobile terminal 2 is not moving, the control unit 223 determines that the acquired BSSID is the BSSID of the access point arranged in the area where the use of the moving route guidance function is prohibited. Regardless of whether or not they match and / or whether or not the position indicated in the position information is a preset position, the display of the route guidance information is limited.

  On the other hand, by executing the processes of steps S304 to S305 and / or S306 to S307, the control unit 223 causes the user carrying the mobile terminal 2 to be in an area where the use of the route guidance function during movement is prohibited. As long as the route guidance information is displayed, the display of route guidance information can be restricted.

  FIG. 8 is a flowchart illustrating an example of an operation flow of the state determination process.

  The operation flow shown in FIG. 8 is executed in step S302 of the flowchart shown in FIG.

  First, the state determination unit 222 determines whether or not the acceleration output from the acceleration sensor 207 is greater than or equal to the first threshold (step S401). The first threshold value is an average value of acceleration obtained in a state where the user carrying the portable terminal 2 is not moving and the acceleration obtained when the user carrying the portable terminal 2 is moving. It is determined to be an intermediate value from the average value.

  Note that the state determination unit 222 may determine whether the average value of acceleration output from the acceleration sensor 207 within a predetermined time (for example, 1 second) is equal to or greater than a first threshold value. Thereby, it becomes possible to improve the determination accuracy of whether or not the mobile terminal 2 is moving.

  If the acceleration output from the acceleration sensor 207 is less than the first threshold (step S401—No), the state determination unit 222 determines that the mobile terminal 2 is not moving (step S402), and ends a series of steps.

  On the other hand, when the acceleration output from the acceleration sensor 207 is equal to or greater than the first threshold (step S401—Yes), the state determination unit 222 determines that the mobile terminal 2 is moving (step S403).

  Next, the state determination unit 222 determines whether or not the magnitude of magnetism output from the geomagnetic sensor 208 is greater than or equal to the second threshold (step S404). The second threshold value is obtained by a prior experiment in an average value of acceleration obtained when the user carrying the mobile terminal 2 is on the train and when the user carrying the mobile terminal 2 is not on the train. It is determined to be an intermediate value from the average value of acceleration.

  The state determination unit 222 may determine whether or not the average value of the magnitude of magnetism output from the geomagnetic sensor 208 within a predetermined time (for example, 1 second) is equal to or greater than the second threshold value. Thereby, it becomes possible to improve the determination accuracy of whether the user carrying the mobile terminal 2 is walking or moving by train.

  Next, when the magnitude of the magnetism output from the geomagnetic sensor 208 is less than the second threshold (step S404-No), the state determination unit 222 determines that the user carrying the mobile terminal 2 is walking ( Step S405), a series of steps is completed.

  On the other hand, when the magnitude of the magnetism output from the geomagnetic sensor 208 is equal to or greater than the second threshold (No in step S404), the state determination unit 222 moves the user carrying the mobile terminal 2 on a train or the like instead of walking. It determines with it being in (step S406), and complete | finishes a series of steps.

  As described above, the state determination unit 222 determines whether or not the mobile terminal 2 is moving based on the acceleration output from the acceleration sensor 207, and determines that the mobile terminal 2 is moving. Based on the magnitude of magnetism output from the sensor 208, it is determined whether or not the user carrying the mobile terminal 2 is walking.

  When the acceleration output from the acceleration sensor 207 is greater than or equal to the first threshold, the state determination unit 222 determines whether the acceleration is greater than or equal to a third threshold greater than the first threshold, and less than the third threshold. If it is, the user may be walking and if it is greater than or equal to the third threshold, it may be determined that the user is moving by train. However, since the speed of the train frequently changes, it is possible to more accurately determine whether or not the user is walking based on the magnitude of magnetism output from the geomagnetic sensor 208. .

  In step S303 in FIG. 7, the control unit 223 does not determine whether or not the mobile terminal 2 is moving, but determines whether or not the user carrying the mobile terminal 2 is walking. Only when the user carrying the mobile terminal 2 is walking, the display of the route guidance information may be restricted. Thereby, the user carrying the portable terminal 2 can use the route guidance function when traveling by train or automobile.
