A. First embodiment:
(A1) Configuration of route guidance system:
FIG. 1 is an explanatory diagram showing a schematic configuration of a route guidance system 10 as an embodiment of the present invention. The route guidance system 10 includes a mobile terminal 100 as a mobile terminal, a route server 200, a map server 300, and an everyday area server 400. The portable terminal 100, the route server 200, the map server 300, and the daily service area server 400 are connected to each other via the Internet INT so that they can communicate with each other. The mobile terminal 100 is connected to the Internet INT wirelessly through the base station BS. The route guidance system 10 displays route guidance from the current position of the user to the destination desired by the user on the display panel 104 of the mobile terminal 100, route guidance by voice output from the voice output unit 106, and the like. It is a system for performing by this alerting | reporting means.

  The mobile terminal 100 is configured around a main control unit 101, and is connected to a communication unit 102, a call control unit 103, a display panel 104, a key input unit 105, an audio output unit 106, and a GPS receiver 107. Further, the main control unit 101 includes a CPU 112, a RAM 114, and a ROM 116. The main control unit 101 controls the overall operation of the mobile terminal 100. The ROM 116 stores a program for executing a route guidance process (to be described later) (hereinafter also referred to as a route guidance program). The CPU 112 reads the program into the RAM 114 and executes it to execute the route guidance process. The communication unit 102 is a circuit for performing data communication or voice communication with the base station BS. The communication unit 102 can access the route server 200, the map server 300, and the daily area server 400 via the base station BS. The call control unit 103 is a circuit that performs incoming calls and calls for voice calls, conversion of voice signals and electric signals, and the like. The mobile terminal 100 operates as a mobile phone by including the communication unit 102 and the call control unit 103.

  The display panel 104 includes a liquid crystal display and a drive circuit that drives the liquid crystal display. The display panel 104 is not limited to a liquid crystal display, and various display devices such as an organic EL display can be employed. The key input unit 105 includes a group of keys such as a direction input key 105a and other operation keys 105b. The user of the portable terminal 100 performs various operations by using these keys. The GPS receiver 107 is a device that receives radio waves transmitted from artificial satellites that constitute a GPS (Global Positioning System / Global Positioning System). The voice output unit 106 includes a speaker for outputting voice during route guidance and a circuit for driving the speaker.

  In response to a route search request from the mobile terminal 100, the route server 200 searches for a recommended route connecting the starting point and the destination designated by the mobile terminal 100, and carries the search result as recommended route data via the Internet INT. It is a server for transmitting to the terminal 100. The route server 200 includes a control unit 201, a communication unit 202, and a route database 214 (route DB 214). The control unit 201 controls the overall operation of the route server 200. The communication unit 202 communicates with the mobile terminal 100 via the Internet INT. In the route database 214, road connection states are recorded. The road connection state is represented by node data representing intersections, branch points, and the like and link data representing roads by line segments connecting the node data.

  The map server 300 is a server for transmitting map data in a specified range to the mobile terminal 100 via the Internet INT in response to a map data acquisition request from the mobile terminal 100. The map server 300 includes a control unit 301, a communication unit 302, and a map database 314 (map DB 314). The control unit 301 controls the overall operation of the map server 300.

In the map database 314, map data supplied to the mobile terminal 100 is recorded in a vector format, a raster format, or the like. This map data includes data representing the shape of topography, buildings, roads, and the like. When there is a map data acquisition request from the mobile terminal 100, the control unit 301 searches the map database 314 for map data in the specified range and transmits the map data to the mobile terminal 100 via the communication unit 302.

  The daily service area server 400 is a server that transmits data defining the daily service area of the user of the mobile terminal 100 to the mobile terminal 100 in response to a request from the mobile terminal 100. The “daily area” refers to the user's living area such as the vicinity of the user's residence of the mobile terminal 100, the vicinity of the school or workplace, the place where the user frequently visits, and the vicinity thereof. In other words, it refers to an area where the user knows a geographically detailed area, various roads, etc., or can estimate various routes. The daily service area server 400 stores the user's daily service area in advance in the daily service area setting process described later.

  The daily zone server 400 includes a control unit 401, a communication unit 402, and a daily zone database 414 (daily zone DB 414). The control unit 401 controls the overall operation of the daily area server 400. The communication unit 402 communicates with the mobile terminal 100 via the Internet INT. The daily service area server 400 specifies a user based on the user information received from the mobile terminal 100, reads the daily service area corresponding to the specified user from the daily service area database 414, and transmits it to the mobile terminal 100.

(A2) Route guidance processing:
Next, route guidance processing performed by the route guidance system 10 will be described. The route guidance process is a process for guiding the user from the current position of the user to the destination set by the user. For the sake of convenience of explanation, in order to distinguish from a route re-search (reroute search) and a route after re-search (reroute), which will be described later, a route that is initially guided at the start of the route guidance process is referred to as a “route”. The “route” corresponds to the “guidance route” recited in the claims. In this embodiment, the route is a route recommended by the route guidance system 10. The other route may be a route specified by a user setting conditions in advance, such as a user setting a waypoint, a passing point, or a route itself.

  FIG. 2 is a flowchart showing a flow of route guidance processing performed by the mobile terminal 100 in the route guidance system 10. The route guidance process is started when the user of the mobile terminal 100 operates the key input unit 105 (the direction input key 105a or the operation key 105b) to start the route guidance program stored in the ROM 116. When the route guidance process is started, the mobile terminal 100 performs a daily area acquisition process (step S110). The daily area acquisition process is a process of acquiring data of a user's daily area (hereinafter also simply referred to as an daily area) from the daily area server 400 and storing it in the RAM 114 for use in the route guidance process. The daily area acquisition process will be described later.

  When the mobile terminal 100 sets the daily zone, the mobile terminal 100 performs route guidance data acquisition processing (step S120). The route guidance data acquisition process is performed from the current position to the destination based on the user's current position specified by the GPS receiver 107 and the user's desired destination input and set by operating the user's key input unit 105. This is a process of acquiring data necessary for guiding the route of the route server 200 and the map server 300. The data necessary for guiding the route includes route data for guidance (hereinafter also referred to as route data) and map image data used for displaying the route to the user. Details of the route guidance data acquisition process will be described later. In this embodiment, it is assumed that the route guidance data acquisition process is performed once during the route guidance process, and data necessary for guiding the route is acquired at one time, but when the data capacity is large, When the route to be guided covers a wide range, the route guidance data acquisition process may be performed at a predetermined timing divided into a plurality of times.

  After the route guidance data acquisition process (step S120), the mobile terminal 100 receives a guidance start instruction given by the user operating the key input unit 105 (step S132: YES), and starts route guidance (step S134). ). The route guidance performed by the portable terminal 100 includes display on the display panel 104 of an image in which the route is superimposed on a map image, and voice guidance of the route using the voice output unit 106.

  When the route guidance is started, the mobile terminal 100 uses the GPS receiver 107 to specify the current position of the mobile terminal 100 (user) every predetermined period (step S136). Then, it is determined whether or not the identified current position is within the area of the daily area acquired in the daily area acquisition process (step S110) (step S138). If the current position is not within the daily range (step S138: NO), the mobile terminal 100 determines whether the current position has deviated from the route being guided (step S140). When the current position deviates from the route, the mobile terminal 100 stores data (hereinafter also referred to as reroute guidance data) for guiding a new route (reroute) from the current position after deviating from the route to the destination. Acquisition is performed (step S142), and reroute guidance is provided to the user (step S144). Similar to the route guidance data acquisition process (step S120), the acquisition of the reroute guidance data is route data (reroute data) necessary for guiding the reroute and a map used to display the reroute to the user. This is processing for acquiring image data from the route server 200 and the map server 300. Since the processing content is the same as the route guidance data acquisition process (step S120), which will be described in detail later, a detailed description of the reroute guidance data acquisition process is omitted.

  On the other hand, when the current position is within the route in step S140 (step S140: YES), the mobile terminal 100 continues the route guidance as it is (step S146). That is, route display on the display panel 104 and route voice guidance using the voice output unit 106 are performed. The processes from step S140 to S146 so far, that is, the process when the current position is not in the daily life (step S138: NO) are the same processes as those of a generally known route guidance system.

  Next, the case where the current position is within the daily range in step S138 (step S138: YES) will be described. When the current position is within the daily range, the mobile terminal 100 determines whether the departure point or the destination point is included in the daily range including the current position (step S148). When the departure point or the destination is included in the daily life area including the current position (step S148: YES), the mobile terminal 100 provides guidance even when the current position is within the route being guided. In both cases, the route is not guided (step S150).

  In this embodiment, “do not guide the route” means that the route guidance data is acquired in a plurality of times, the route guidance data is acquired, the route display, the route voice guidance, and the current position deviates from the route. This means that the portable terminal 100 does not perform a function for guiding the route to the user (hereinafter also referred to as a guidance function) such as acquisition of reroute guidance data, reroute display, and reroute voice guidance. However, the present invention is not limited to this, and for example, only a route display or a reroute display may be performed and a route voice guidance or a reroute voice guidance may not be performed.

  On the other hand, when the departure point or the destination point is not included in the daily sphere including the current position in step S148 (step S148: NO), the mobile terminal 100 is within the route the current position is guiding. In addition, even when the route deviates from the route being guided, only the route display is performed regardless of the case (step S152). When the starting point or destination point is not included in the daily sphere that includes the current position, the point that is passing while moving (passing point) is the daily sphere, or between the current position and the destination. This is a case where there is a transit point and the transit point is included in the daily life zone. In this case, “only display route” means that only the route at the beginning of guidance is displayed and the route voice guidance is not performed. Further, even when the current position deviates from the route being guided, acquisition of reroute guidance data, reroute display, and reroute voice guidance are not performed. Thus, in the processing from step S148 to S152, that is, the processing in the case where the current position is within the daily range (step S138: YES), the mobile terminal 100 performs at least a part of the guidance function for the user. Absent.

  The mobile terminal 100 repeatedly performs the processes in steps S136 to S152 until the user arrives at the destination or the user finishes the route guidance process, and arrives at the destination or the user finishes the route guidance process. At the same time, the route guidance process ends.

  As described with reference to FIG. 2, the mobile terminal 100 determines whether or not the current position is within a daily range, and whether the daily range includes a departure point, a transit point (including a passing point), or a destination. The guidance function to be performed differs depending on the current position. In order to facilitate understanding of the contents of the guidance function performed by the portable terminal 100 in FIG. 2, the guidance function performed by the portable terminal 100 for each state of the current position will be described with reference to FIGS. 3, 4, 5, and 6. I will explain. In Fig. 3, the current position is divided into three cases: around the departure point, waypoint (passage point), and destination. In addition, whether the current position is within or outside of the daily life, within or outside the route (departs from the route) It is a table summarizing the contents of the guidance function performed by the mobile terminal 100 in each case of whether or not there is a deviation. FIG. 4 is an explanatory diagram for explaining the contents of the guidance function performed by the mobile terminal 100 when the departure place is included in the user's daily range. FIG. 5 is an explanatory diagram for explaining the contents of the guidance function performed by the mobile terminal 100 when a transit point (passage point) is included in the user's daily range. FIG. 6 is an explanatory diagram for explaining the contents of the guidance function performed by the mobile terminal 100 when the destination is included in the user's daily range.

  A case where the departure place is included in the daily range will be described with reference to FIGS. 3 and 4. A solid line shown in FIG. 4 indicates a route recommended and guided by the route guidance system 10, a broken line indicates a route (deviation route) when the user deviates from the route, and a two-dot chain line indicates a route guidance. The reroute which the system 10 searched and showed is shown. In FIG. 4, the hatched area indicates the daily life area.

  As shown in FIG. 4, when the user starts moving from the departure place and moves within the daily range, the mobile terminal 100 displays the display panel regardless of whether the route is moving or the departure route. Only the current position is displayed on the map image shown in 104, and route display, route voice guidance, reroute search, reroute display, and reroute voice guidance are not performed. That is, it corresponds to “no route guidance (FIG. 2: step S150)”. In FIG. 4, for convenience of explanation, the route is displayed in the daily range, but the actual display panel 104 does not display the route in the daily range.

  When the user moves from the inside of the daily life area to the outside and the user is moving on the route, the mobile terminal 100 performs route display and route voice guidance. That is, it corresponds to “route guidance (FIG. 2: step S146)”. On the other hand, when the user moves from the inside of the daily area to the outside and the user is moving on the departure route, the mobile terminal 100 performs a reroute search as the route guidance system 10 at the boundary of the daily area. Starts, and displays the reroute from the current position to the destination and provides the reroute voice guidance. That is, it corresponds to “reroute guidance (FIG. 2: step S144)”. In this case, at least two routes can be adopted as the reroute. The first route is a route for guiding the user from the current position to the original route, as shown as reroute P in FIG. The second route is a route recommended between the current position and the destination without considering the original route, as shown as reroute Q in FIG. Of these two reroutes (P or Q), the route guidance system 10 may be set in advance, or the two reroutes may be displayed on the display panel 104 and selected by the user. Good. In addition, the mobile terminal 100 or the user may determine in consideration of various conditions such as traffic jam information, the shortest distance, and the type of road (general road or highway).

  Next, the case where a transit point (including a passing point) is included in the daily range will be described with reference to FIGS. 3 and 5. As shown in FIG. 5, when the user is moving within a daily range as a transit point, the mobile terminal 100 only displays the route, regardless of whether the route is moving or the departure route. There is no voice guidance for the route. When the user moves from the inside of the daily life area to the outside and the user is moving on the route, the mobile terminal 100 performs route display and route voice guidance. That is, it corresponds to “route guidance (FIG. 2: step S146)”. On the other hand, when the user moves from the inside of the daily area to the outside and the user is moving on the departure route, the mobile terminal 100 performs a reroute search as the route guidance system 10 at the boundary of the daily area. , Display reroute from current position to destination and perform reroute voice guidance. This corresponds to “reroute guidance (FIG. 2: step S144)”. As for the reroute in this case, two reroutes of the reroute P and the reroute Q can be adopted as in the case where the departure place is included in the daily range (FIG. 4).

  Finally, the case where the destination is included in the daily range will be described with reference to FIGS. 3 and 6. As shown in FIG. 6, when the user starts moving from the departure place and is moving outside the daily life area and moving on the route, the mobile terminal 100 displays the route display and Provides route voice guidance. That is, it corresponds to “route guidance (FIG. 2: step S146)”. When the user is moving outside the daily life area and is moving on a deviated route, the route guidance system 10 starts a reroute search, displays a reroute from the current position to the destination, and reroute voice guidance. I do. This corresponds to “reroute guidance (FIG. 2: step S144)”. As for the reroute in this case, two reroutes of the reroute P and the reroute Q can be adopted as in the case where the departure place is included in the daily range (FIG. 4).

  When the user moves from outside the daily life zone to the inside, the mobile terminal 100 displays the current position on the map image shown on the display panel 104 regardless of whether the route is moving or the departure route. Only route display, route voice guidance, reroute search, reroute display, and reroute voice guidance are not performed. That is, it corresponds to “no route guidance (FIG. 2: step S150)”. As described above, the guidance function performed by the mobile terminal 100 differs depending on the state of the current position. The details of the route guidance process performed by the mobile terminal 100 have been described above.

(A3) Daily area acquisition process and route guidance data acquisition process:
Next, daily area acquisition processing (FIG. 2: step S110) and route guidance data acquisition processing (FIG. 2: step S120) in route guidance processing will be described. FIG. 7 is a flowchart showing a flow of daily area acquisition processing performed by the route guidance system 10. When the route guidance system 10 starts the daily area acquisition process, the mobile terminal 100 transmits information (user information) identifying the user of the mobile terminal 100 to the daily area server 400 (step S111). As the user information, for example, information that can identify an individual user such as a user ID or an email address assigned to each user who uses the route guidance system 10 can be used.

  When receiving the user information (step S411), the daily service area server 400 (control unit 401) receives the data from the daily service area data stored in the daily service area database 414 (see FIG. 1). The daily area data of the user corresponding to the user information is read (step S402). Then, the read daily zone data is transmitted to the portable terminal 100 via the Internet INT (step S413). The mobile terminal 100 receives the daily zone data from the daily zone server 400 (step S112), and stores the data in the RAM 114 to set the daily zone area (step S113). In this embodiment, the user's daily area stored in the daily area database 414 is manually set by the user in advance via the portable terminal 100. In addition, as described in the second embodiment later, it is assumed that the daily service area server 400 acquires information about the area where the user has moved, automatically identifies the user's daily service area, and stores it in the daily service area database 414. Also good. In this way, the route guidance system 10 performs daily area acquisition processing.

  Next, route guidance data acquisition processing (FIG. 2: step S120) in route guidance processing will be described. FIG. 8 is a flowchart showing a flow of route guidance data acquisition processing performed by the route guidance system 10. When the route guidance system 10 starts the route guidance data acquisition process, the mobile terminal 100 specifies the current position of the mobile terminal 100 using the GPS receiver 107 (step S121). Thereafter, when the user inputs a destination using the key input unit 105, the mobile terminal 100 transmits the current position and destination data (longitude / latitude) to the route server 200, and from the current position to the destination. The route server 200 is requested for recommended route data (route data) (step S122). When the route server 200 receives the route data request from the mobile terminal 100 (step S201), the route server 200 searches for a recommended route using the node data and link data stored in the route database 214 (step S202). The route server 200 transmits route data of the searched recommended route to the mobile terminal 100 (step S203). The portable terminal 100 receives the route data transmitted from the route server 200 and stores it in the RAM 114 (step S123).

  Next, the mobile terminal 100 requests the map server 300 for map image data (map data) for displaying the received route data superimposed on the map image on the display panel 104 (step S124). Specifically, the coordinates (longitude and latitude) of the four corners of the rectangular map image necessary for superimposing the route data are transmitted to the map server 300, and the map data of the area specified by the coordinates is transmitted. Request. Upon receiving a map data request from the mobile terminal 100 (step S301), the map server 300 reads map image data of the area corresponding to the request from the map database 314 (step S302) and transmits it to the mobile terminal 100 (step S302). Step S303). When the mobile terminal 100 receives the map data from the map server 300 (step S125), the mobile terminal 100 superimposes the map data and the previously acquired route data and displays the image on the display panel 104 (hereinafter also referred to as a route display image). ) And stored in the RAM 114 (step S126). In this way, the route guidance system 10 performs route guidance data acquisition processing.

  As described above, when guiding the route to the user, the route guidance system 10 does not perform at least a part of the plurality of guidance functions when the current position is the area of the user's daily area. . Also, if the user departs from the route within the daily range, part of the guidance function is not performed. In daily life, the user has geographical knowledge of the area, so even if there is no guidance function, it is often possible to move more smoothly by moving with his own geographical knowledge. Therefore, in the route guidance system 10, when the current position of the user is within the daily range, processing such as route display, route voice guidance, reroute display, and voice guidance that the user often feels as excessive guidance is performed. Therefore, it is possible to suppress troublesomeness felt by the user by the guidance function.

  In the present embodiment, the user's daily sphere is acquired from the daily sphere server 400, but the user may set using the mobile terminal 100, or the mobile terminal 100 may use the GPS receiver 107. An area in which the user's stay time is longer than a predetermined time may be extracted and specified as an everyday area. Further, the daily service area server 400 acquires data related to various user movements such as the current position and stay time from the mobile terminal 100, and the daily service area server 400 identifies and stores the user's daily service area. Can do. Hereinafter, an embodiment in which the daily area server 400 specifies and stores the daily area of the user will be described as a second example.

B. Second embodiment:
Next, as a second embodiment, a mode in which the daily service area server 400 identifies each user's daily service area, and sets and stores the user's daily service area will be described.
(B1) Daily zone setting system:
FIG. 9 is an explanatory diagram illustrating a schematic configuration of the daily area setting system 20 that automatically generates and sets an daily area for each user. The daily area setting system 20 includes the mobile terminal 100 and the daily area server 400 described in the first embodiment. The portable terminal 100 and the daily service server 400 are connected via the Internet INT. Since the configuration of the portable terminal 100 is the same as that of the first embodiment, the description thereof is omitted. In the first embodiment, the daily zone server 400 has been described as including the control unit 401, the communication unit 402, and the daily zone database 414. However, in this embodiment, the daily zone server 400 has a more detailed configuration. I will explain it first.

  As shown in FIG. 9, the daily zone server 400 includes a control unit 401, a communication unit 402, a positioning information storage unit 403, a basic data generation unit 404, a daily mesh generation unit 405, a period-specific mesh generation unit 408, and an daily range specification. A unit 409, a positioning information database 410, a basic data database 411, a daily mesh database 412, a period-specific mesh database 413, and an everyday area database 414. Further, the daily mesh generation unit 405 includes a stay time / positioning count totaling unit 406 and a distribution complementing unit 407. Processing performed by each functional unit will be described in detail later.

(B2) Daily zone setting process:
FIG. 10 is a flowchart showing the flow of the daily area setting process performed by the daily area setting system 20. First, the general flow of the daily area setting process will be described with reference to FIG. 10, and then the details of each process will be described. In the present embodiment, the daily area setting process is started when the user of the mobile terminal 100 starts a program (daily area setting program) stored in the ROM 116 of the mobile terminal 100. In addition, the daily service area server 400 may be started by transmitting an instruction to start the daily service area setting process to the mobile terminal 100 via the Internet INT.

  When the daily area setting process is started, the mobile terminal 100 uses the current position (hereinafter also referred to as a positioning point) specified by the GPS receiver 107, the positioning time, and the user ID as daily positioning information for each predetermined period. The daily server 400 transmits the received positioning information (see FIG. 11) to the positioning information database 410 (step S502). As a result, the positioning information history corresponding to the movement of the user is stored in the positioning information database 410. The positioning information will be described in detail later.

  Thereafter, the daily service server 400 generates basic data (see FIG. 12) based on the positioning information. The basic data is data in which a positioning point and a positioning time for each positioning date for each user are associated with each area (hereinafter also referred to as a mesh area) obtained by dividing the map into meshes based on longitude and latitude. . The daily service server 400 generates basic data and stores it in the basic data database 411 (step S504). The basic data will be described in detail later.

  The daily service server 400 generates daily basic mesh data representing the number of times of positioning in each mesh area and the user's stay time for each predetermined unit period (for example, every day) based on the basic data after the basic data is generated. (See FIG. 14) is generated (step S510). Then, the generated daily mesh data is stored in the positioning information database 410.

  Based on the generated daily mesh data, the daily service server 400 aggregates the positioning count, staying time, and staying days of each mesh area in a predetermined counting period, and counts the positioning count, staying time, Aggregate period-specific mesh data associated with the number of stay days is generated (step S530). The daily zone server 400 stores the aggregated mesh data by period (see FIG. 20) in the period-by-period mesh database 413.

  The daily service area server 400 determines a predetermined daily service area condition determined in advance from any one of the number of times of positioning, the staying time, and the number of staying included in the mesh data for each counting period, or any combination of two or more thereof. Extract the mesh area to fill. Based on the extracted mesh area, the user's daily sphere is specified. Then, the identified daily area is stored in the daily area database 414 as daily area data (see FIG. 23) (step S540).

  Next, details of each process in the daily zone setting process will be described for each process shown in the flowchart of FIG. First, in step S <b> 502, the daily service server 400 receives positioning information from the mobile terminal 100 and stores it in the positioning information database 410. FIG. 11 is an explanatory diagram showing an example of a data structure of positioning information stored in the positioning information database 410. As shown in FIG. 11, the positioning information database 410 stores data such as “positioning time”, “user ID”, “latitude”, and “longitude” in association with each other as positioning information history.

  Next, the daily zone server 400 generates basic data based on the positioning information in step S504. FIG. 12 is an explanatory diagram showing an example of the data structure of basic data stored in the basic data database 411. As shown in FIG. 12, the basic data stores data such as “user ID”, “positioning date”, “mesh number”, and “positioning time” in association with each other. The mesh number is a number that uniquely identifies a mesh region. FIG. 13 is an explanatory diagram for explaining how basic data is generated based on positioning information stored in the positioning information database 410. In FIG. 13, for the positioning date (2010/3/3) of the user (Mr. AAAAA), basic data B1 in which positioning points and positioning times are associated with each mesh area is described as the user's action trajectory on the corresponding day. Yes. For the mesh region, the size of the divided region can be set as appropriate according to the specifications and design. For example, if the user wants to specify an area where he / she frequently stays, the size can be set larger, and if he / she wants to specify a store where the user frequently visits, the size can be set smaller.

[Daily mesh data generation processing]
Next, the daily zone server 400 generates daily mesh data based on the basic data in step S510. FIG. 14 is an explanatory diagram showing an example of the data structure of daily mesh data. The daily mesh data is data representing the number of times of positioning in each mesh region for each predetermined unit period (for example, every day) and the user's stay time for each user. As shown in FIG. 14, the daily mesh data stores data such as “user ID”, “positioning date”, “mesh number”, “stay time”, and “number of times of positioning” in association with each other. The predetermined unit period in the daily mesh data is the minimum unit period for generating the daily mesh data, and can be designed as appropriate according to the specification / design. In this embodiment, one day is set, but the period is not particularly limited, and for example, a unit period such as a half day, a week, or a month may be set. In this embodiment, since the unit period is described as one day, it is called “daily mesh data”. However, any other unit period may be adopted as long as it is a unit period. May be referred to as mesh data by unit period.

  FIG. 15 is an explanatory diagram for explaining how daily mesh data is generated based on the basic data B1 stored in the basic data database 411. FIG. FIG. 15 shows mesh data M1 in which the stay time and the number of times of positioning are associated with each mesh area for the positioning date (2010/3/3) of the user (Mr. AAAAA). In this embodiment, the number of positioning times and the stay time are calculated and associated for each mesh region, but only the number of positioning times or the stay time may be calculated and associated. Although there are more positioning points than the number shown in FIG. 15 in the basic data B1, for convenience of explanation, positioning points are shown as far as possible by way of illustration.

  In order to generate such daily mesh data, the daily mesh generation unit 405 includes a stay time / positioning count totaling unit 406 and a distribution complementing unit 407 (see FIG. 9). Based on the basic data stored in the basic data database 411, the stay time / positioning count totaling unit 406 calculates the number of positioning points in each mesh area and the stay time of the user of the mobile terminal 100 for each predetermined unit period. Then, each mesh region is associated with the calculated number of positioning times and stay time. The number of positioning times in each mesh area is calculated by summing the number of times positioning has been performed in the corresponding mesh area. The staying time in each mesh area is calculated by summing the distribution times allocated to the mesh area by the distribution complementing unit 407 described later.

  The distribution complementing unit 407 selects the first positioning point and the second positioning point arranged next to the first positioning point on the time axis from the positioning points associated with the mesh region (see FIG. 16). The first positioning point is also called a pre-movement point, and the second positioning point is also called a post-movement point. Next, the time from the first positioning time of the second positioning point to the second positioning time of the second positioning point (hereinafter referred to as “time between positioning points”), the second positioning point, and the first positioning point. Distance (hereinafter referred to as “time between positioning points”). Then, an allocation condition is determined based on the time between the positioning points and the distance between the positioning points, and the time between the positioning points is set on the movement path from the first positioning point to the second positioning point according to the determined allocation condition. Allocate to the mesh area (including the first mesh area of the first positioning point and the second mesh area of the second positioning point). The allocation includes allocation of 0 hours. In this case, the allocation is substantially the same as not allocation.

  The distribution conditions can be set as appropriate according to the specifications and design, and there is no particular limitation on the contents thereof, but in this embodiment, according to the transmission conditions and configuration of positioning information from the mobile terminal, as follows: Allocation conditions are set. Specifically, the mobile terminal 100 according to the present embodiment transmits positioning information to the daily server 400 at a predetermined transmission time interval (for example, 5 minutes). If the user does not move, the reason for saving power consumption, etc. Is configured not to transmit positioning information. That is, when the user is in the radio wave range, the positioning information from the mobile terminal 100 is transmitted at a predetermined transmission time interval only when the user is moving. Therefore, the user's stay at the first positioning point, which is the point before moving, is the time obtained by excluding the moving time from the time between the measuring points between the first positioning time and the second positioning time (hereinafter referred to as “moving time subtracted time”). Therefore, the movement time subtracted time is allocated to the mesh area of the first positioning point.

  Next, when it is possible to estimate the user's movement content (moving means and movement route) between the first positioning point and the second positioning point (when there is continuity between the first positioning point and the second positioning point) ) Distributes the movement time substantially evenly to the mesh region located on the estimated movement route (hereinafter referred to as “estimated movement route”) from the first positioning point to the second positioning point (first distribution condition). ). That is, the stay time is supplemented for the mesh region on the estimated movement route. FIG. 16 is a diagram illustrating a state in which stays are distributed according to the first distribution condition. In the figure, first, the movement time subtracted time (5 minutes (300 minutes) obtained by subtracting the movement time (5 minutes) from the time between measurement points (10 minutes) between the first positioning point and the second positioning point. Second)) is distributed to the mesh area of the first positioning point. Next, in order to supplement the stay time in the mesh area between the first positioning point and the second positioning point, the moving time (5 minutes) is set in the six mesh areas located on the connection between the first positioning point and the second positioning point. ) Is distributed substantially evenly (in 50 seconds increments).

  On the other hand, when the user's movement content between the first positioning point and the second positioning point cannot be estimated, for example, when the distance between the positioning points between the first positioning point and the second positioning point is a predetermined distance or more, If there is no continuity between the first positioning point and the second positioning point, such as when the time between the positioning points between the first positioning point and the second positioning point is abnormal for a predetermined time, the moving time mesh area No allocation is made (0 hours are allocated) (second allocation condition). That is, the stay time in the mesh area is not supplemented. FIG. 17 is a diagram illustrating a state in which stay time is distributed according to the second distribution condition. In the figure, first, the movement time (20 minutes) between the first positioning point and the second positioning point is calculated from the distance between positioning points (10 km) and a predetermined speed (eg, 30 km), and the time between the measuring points is calculated. The movement time subtracted time (100 minutes) obtained by subtracting the movement time (20 minutes) is distributed to the mesh area of the first positioning point. In this case, since the mesh region located between the first positioning point and the second positioning point is not complemented, the movement time is not distributed.

  The method for determining whether or not the movement content can be estimated can be appropriately set according to the specifications and design, and the content is not particularly limited. For example, the time between positioning points and / or the distance between positioning points is a predetermined reference time. If it is less than and / or less than the predetermined reference distance, it is assumed that the user's movement route can be estimated by assuming that the movement is by walking or the like. On the other hand, if it is not less than the predetermined reference time and / or less than the predetermined reference distance, it can be assumed that the user's movement route cannot be estimated by considering that the movement is, for example, when using the subway.

  The travel time calculation method can be set as appropriate according to the specifications and design, and the content thereof is not particularly limited. For example, a method using the transmission time interval of the mobile terminal 100, or a distance between positioning points And a method of calculating the travel time from a predetermined speed according to the travel means (eg, train, car, walk). In the present embodiment, in the case of the first distribution condition, the transmission time interval (for example, 5 minutes) of the positioning information in the mobile terminal 100 is set as the time of movement. In the case of the second distribution condition, the travel time from the first positioning point to the second positioning point is calculated based on the distance between the positioning points and a predetermined speed (for example, 30 km) set in advance. Note that the predetermined hourly speed can be appropriately set according to the estimated moving means and the like. For example, for the first distribution condition, the traveling time may be calculated using the hourly walking speed.

  Also, the method for specifying the movement route can be set as appropriate according to the specification and design, and the content thereof is not particularly limited. In the present embodiment, however, the connection is made by connecting the first positioning point and the second positioning point. Represents the travel route. In addition, a connection is not restricted to a straight line, For example, it can have a shape along the arbitrary movement paths estimated according to a road, a route, a building, etc. Further, among the mesh regions located on the connection, mesh regions other than the mesh regions of the first positioning point and the second positioning point are referred to as complementary mesh regions.

  Since the daily mesh generation unit 405 manages the positioning information for each predetermined unit period, when the first positioning point and the second positioning point straddle the day (reference time (eg, 0: 00/24: 00)). ). That is, the first positioning point (hereinafter referred to as “first positioning point”) and the last positioning point (hereinafter referred to as “last positioning point”) in the unit period before the movement to be combined. A positioning point or a post-movement positioning point belongs to another day. Therefore, in the present embodiment, as the third distribution condition, for the first positioning point, since the corresponding pre-movement positioning point belongs to another day, the time from the reference time (for example, 0:00) to the positioning time of the first positioning point. Time is allocated to the mesh area of the first positioning point as stay time. For the last positioning point, since the corresponding post-movement positioning point belongs to another day, the time from the positioning time of the last positioning point to the reference time (for example, 24:00) is displayed in the mesh area of the last positioning point. To distribute. In the third distribution condition, the maximum time allocated to the mesh area can be set, and the content thereof is not particularly limited, but a maximum of 6 hours (maximum distribution time) is set in the present embodiment.

  FIG. 18 is a diagram illustrating a state in which the stay time is distributed according to the third distribution condition. In the figure, 6 hours (360 minutes), which is the maximum allocation time, is allocated for the first positioning point (positioning time 7:30), and for the last positioning point (positioning time 23:30), 30 minutes from 0 to 0:00 are allocated.

  Next, the flow of the above described daily mesh data generation process (daily mesh data generation process) (FIG. 10: step S510) will be described. FIG. 19 is a flowchart showing the flow of daily mesh data generation processing. First, the daily service server 400 determines, based on the basic data, from the positioning points on the mesh area, for example, in accordance with time series, a set of the first positioning point of the positioning point before movement and the second positioning point of the positioning point after movement. If the group is identified and the group can be identified (step S511: YES), the process proceeds to step S512 to apply the first distribution condition or the second distribution condition. If the group cannot be identified, that is, the first If there is no continuity between the positioning point and the second positioning point (step S511: NO), the process proceeds to step S519 to apply the third distribution condition.

  When the routine server 400 proceeds to step S512, it calculates the distance between the first positioning point and the second positioning point, the first positioning time of the first positioning point, and the second positioning point of the second positioning point. The time between positioning points is calculated between times. As an example of the distribution condition, the daily service area server 400 determines whether the calculated distance between positioning points is less than a predetermined reference distance and whether the calculated time between positioning points is less than a predetermined reference time (step S513). ) If the determination result is right, the process proceeds to step S514 in order to apply the first distribution condition. If the determination result is negative, the process proceeds to step S517 to apply the second distribution condition.

  When the daily zone server 400 proceeds to step S514, it sets the transmission time interval of the positioning information in the mobile terminal to the travel time (step S514). Then, the travel time subtracted time is calculated by subtracting the travel time from the time between positioning points, and the calculated travel time subtracted time is allocated to the first mesh region to which the first positioning point belongs as the allocated stay time ( Step S515). Next, the movement time is distributed approximately evenly as the distribution stay time to one or a plurality of mesh regions located on the connection between the first positioning point and the second positioning point (step S516). Thereby, the allocated stay time is appropriately allocated to the first mesh area, the second mesh area, and the complementary mesh area (see FIG. 16).

  On the other hand, when the routine server 400 proceeds to step S517, it calculates the travel time based on the distance between the positioning points and the predetermined speed information (step S517). Then, the travel time subtracted time is calculated by subtracting the travel time from the time between positioning points, and the calculated travel time subtracted time is allocated to the first mesh region to which the first positioning point belongs as the allocated stay time ( Step S518). In addition, the allocation stay time is not distributed to the second mesh area to which the second positioning point belongs or other mesh areas. Thereby, the allocated stay time is appropriately allocated to the first mesh area (see FIG. 17).

  In addition, since the result of the determination in step S511 is negative, the daily zone server 400, when the process proceeds to step S519, the last positioning point at which the first positioning point at which the target positioning point was first positioned on the corresponding day was determined last. If it is the first measurement point, the time from the reference time of 0:00 to the positioning time of the target positioning point is distributed to the target mesh region within a predetermined maximum time (step S520). ). On the other hand, when the target positioning point is the last positioning point, the time from the positioning time of the target positioning point to 24 o'clock which is the reference time is allocated to the target mesh region within a predetermined maximum time (step S521). ). Accordingly, the allocated stay time is appropriately allocated to the mesh areas of the first positioning point and the last positioning point (see FIG. 18).

  The daily service server 400 calculates the staying of the target mesh area based on the allocated stay time allocated to the mesh area, and determines the number of positioning of the mesh area based on the number of times the positioning point is positioned in the mesh area. (Step S522). Note that the staying time is added to the complementary mesh region, but the positioning point is not added.

  Next, the daily zone server 400 determines whether or not there is a positioning point to be processed next. If there is a positioning point to be processed next (step S523: YES), the routine returns to step S511. Repeat the above process. On the other hand, if there is no positioning point to be processed next, the process is terminated (step S523). In this way, the daily mesh data generation process is performed.

[Generation of mesh data by aggregation period]
Next, in step S530 (see FIG. 10), the daily service server 400 generates period-specific mesh data based on the daily mesh data (period-specific mesh data) (total period-specific mesh data generation process). I do. The mesh data generation processing for each period is performed by the period-specific mesh generation unit 408. The period-specific mesh generation unit 408 counts the number of times of positioning, staying time, and number of stays included in the daily mesh data (period-specific mesh data) for each predetermined counting period, and counts the number of positioning times and stays that are counted in each mesh area. The mesh data according to the total period in which the time and the number of stay days are associated are generated (see FIG. 20). The predetermined counting period can be set as appropriate according to the design and specifications, and the contents of the period are not particularly limited. For example, the counting period such as the latest 7 days, the latest 30 days, the latest 180 days, the latest 365 days, etc. Can be set. A plurality of total periods may be set at the same time. If mesh data by aggregation period already exists, daily mesh data for the newly added target date (for example, the latest positioning date) and the subtraction target date (for example: the oldest positioning date in the existing aggregation period) Is read from the daily mesh database 412 and the stay time, the number of times of positioning, and the number of stay days are added for each mesh area, while the stay time, the number of times of positioning, and the number of stay days are subtracted for each mesh area. To do.

  FIG. 20 is a diagram illustrating a state in which mesh data for each aggregation period is generated from mesh data for each unit period. This figure shows a state in which the stay time, the number of times of positioning, and the number of stay days are associated with each mesh region in the mesh data M6 by total period generated from the mesh data by day (mesh data by unit period) M5. . In the present embodiment, the case where the number of positioning times, the staying time, and the number of positioning days are calculated and associated for each mesh region is described. However, any one or two of the positioning times, the staying time, and the positioning days are described. May be calculated and associated with each other.

  Next, the flow of mesh data generation processing for each aggregation period will be described. FIG. 21 is a flowchart showing the flow of the total period generation mesh data generation process. The daily zone server 400 determines whether or not the mesh data for each aggregation period of the target aggregation period exists in the mesh database for each period 413, and if already generated (step S531: YES), the process proceeds to step S532. If it has not been generated yet (step S531: NO), the process proceeds to step S533.

  When the routine server 400 proceeds to step S532, it reads the existing mesh data by total period from the mesh database 413 by period, and reads the daily mesh data by the addition target date and the subtraction target date from the daily mesh database 412. Then, for each mesh area, the stay time, the number of positioning times, and the number of stay days of the addition target date are added, while the stay time, the number of positioning times, and the stay days of the subtraction target date are subtracted.

  When the routine server 400 proceeds to step S533, it reads the daily mesh data for the target aggregation period from the daily mesh database 412 and totals the stay time, the number of positioning times, and the number of stay days for the target aggregation period. The daily zone server 400 stores the generated mesh data for each period in the mesh database 413 for each period (step S534). In this way, the mesh data generation process for each aggregation period is performed.

[Daily-area identification processing]
Next, the daily service area server 400 performs daily service area specifying processing for specifying the daily service area of the user based on the generated mesh data for each total period as step S540 (see FIG. 10). The daily area specifying process is performed by the daily area specifying unit 409. The daily area identification unit 409 selects a mesh area in which any one of the number of positioning times, the staying time, and the number of staying included in the mesh data for each counting period or any combination of two or more thereof is a predetermined threshold or more. By extracting, the user's daily sphere is set. Hereinafter, details of the daily area identification process will be described with reference to FIGS. 22, 23, and 24.

  FIG. 22 is a diagram illustrating an example of daily life conditions. Although the contents according to the specification design can be set in the daily sphere conditions, and there is no particular limitation, in the figure, the daily sphere types and conditions are stored in association with each other. More specifically, “daily total period”, “stay days”, and “stay time” are set for daily life area A, and “target total period”, “stay days”, “stay time” are set for daily life area B. And “number of times of positioning” are set, and “daily counting period” and “stay days” are set in the daily life zone C. Further, for each item, an arbitrary period and the number of days, time, and number of times as a threshold are set for each type of daily area. As shown in the figure, the conditions for the daily life can be set according to the type of the daily life to be extracted. For example, it is possible to specify the commute route if you do not consider the stay time and the number of positionings with emphasis on the length of stay, and if you do not consider the stay days with emphasis on the stay time, the number of visits is small It is possible to specify a place where a person stays for a long time (eg, home). In addition, if you set a long period for the target aggregation period, you can prevent the daily area from disappearing when you go on a long trip or a business trip, while if you set a short period for the target aggregation period, It can be easily identified.

  FIG. 23 is a diagram illustrating an example of the identified daily area. In the figure, for each user ID, the type of everyday area and the mesh number are stored in association with each other. According to the figure, it can be seen that the mesh number of the identified daily area varies depending on the type of daily area.

  FIG. 24 is a diagram for explaining a situation in which the daily life area is specified from the mesh data for each counting period. In the same figure, from the mesh data M7 for the most recent 30 days, a daily area is identified by extracting a mesh area that meets the condition of “stay for 300 minutes or more and 3 days or more”, or mesh data M8 for the most recent 7 days Shows a case where the daily sphere is specified by extracting a mesh region that matches the condition of “stay for 60 minutes or longer and 2 days or longer”. A plurality of daily areas can be specified, and the daily area can be further subdivided by referring to the values of stay time and stay days of the extracted mesh area. For example, a mesh area with high values can be judged as home or office, a mesh area with many days but a short stay time can be judged as a transfer station on a commuting route, or a mesh area with few days but a long stay time Can be determined as a user's favorite store.

  Next, the flow of daily area identification processing will be described. FIG. 25 is a flowchart showing the flow of the daily area identification process. The daily service area server 400 refers to the daily service area condition of the target daily service area from the daily service area database 414 (step S541), and reads the corresponding mesh data by total period from the time period mesh database 413. A mesh region that matches the sphere condition is extracted and set as the daily sphere (step S542). The daily service area server 400 stores the set daily life area type and mesh number in the daily service area database 414 in association with each other (step S543). In this way, the daily service area server 400 performs the daily service area specifying process.

  The daily area server 400 reads the daily area for each user stored in the daily area database 414 by the daily area setting process described above by the daily area setting system 20 as the route guidance system 10 in response to a request from the portable terminal 100. (FIG. 7: Step S412) By performing transmission to the portable terminal 100, daily area income processing (FIG. 7), that is, route guidance processing (FIG. 2) as the route guidance system 10 is performed. In addition, although the daily life database 414 stores a plurality of types of daily life for each user (see FIG. 23), the route guidance system 10 determines which daily life is transmitted to the mobile terminal 100. It may be set in advance, or may be appropriately set according to various conditions such as the length of the distance to the destination and the width of the range for route guidance during the route guidance process.

  As described above, by adopting the aspect described in the present embodiment, the user's daily life area can be automatically specified between the mobile terminal 100 and the daily life server 400 by the movement of the user. In other words, it is possible to avoid the user manually setting the daily life zone.

C. Third embodiment:
Next, a third embodiment will be described. In the second embodiment, the user's daily area generated by the daily area setting process performed between the mobile terminal 100 and the daily area server 400 is used as it is, but the third embodiment The daily area acquired from the daily area server 400 is not applied as it is to the route guidance process, but an area smaller than the daily area acquired from the daily area server 400 (hereinafter also referred to as a small daily area) is determined, and the route guidance process (FIG. This is applied to the determination of whether or not the current position of the user is within the daily range in step S138 of 2).

  Regarding the method for determining the sub-daily life area, the mobile terminal 100 determines the sub-daily life area by performing processing for narrowing the peripheral edge of the daily life area acquired from the daily service area server 400 equally by a predetermined distance. Various confirmation methods such as a method of confirming a region obtained by deleting a predetermined number of mesh regions constituting the daily life area acquired from the server 400 evenly from the periphery as a small daily life area can be employed.

  FIG. 26 explains route guidance processing in the case where the sub-daily sphere determined by the above method is applied to the determination of whether or not the current position of the user is in the daily sphere in step S138 of the route guidance processing (FIG. 2). It is explanatory drawing. FIG. 26 is an explanatory diagram showing, as an example, the processing contents of guidance performed by the mobile terminal 100 when the departure place is included in the daily range. As shown in FIG. 26, the route guidance process according to the third embodiment uses only the small daily area when determining whether or not the current position of the user is within the daily area. Same as example.

  As described above, in the third embodiment, “route guidance is not performed” in the inner area, that is, the sub-daily area where the user is more surely geographically detailed among the areas constituting the daily area ( FIG. 2: Step S150) ”and“ Route display only (Step S152) ”can be used to perform route guidance processing that does not perform part of the guidance function. In other words, the guidance process similar to the normal area (the area other than the daily area) such as the route guidance and the reroute guidance is performed in the area where the user has a low probability of being geographically detailed among the areas constituting the daily area. By doing in this way, the route guidance process which does not perform a part of guidance function can be performed more reliably by a user limited to a geographically detailed area.

D. Fourth embodiment:
In the first embodiment and the second embodiment, the mobile terminal 100 is obtained from the everyday area server 400 and uses the everyday area as it is, but in the fourth embodiment, the portable terminal 100 obtains from the everyday area server 400. If the daily area acquired from the daily area server 400 satisfies (or does not satisfy) the predetermined daily area without applying it to the route guidance process as it is, an area larger than the acquired daily area (hereinafter, (Also referred to as “daily life zone”) is determined and applied to the determination of whether or not the current position of the user is within the daily life range in step S138 of the route guidance process (FIG. 2). FIG. 27 is an explanatory diagram illustrating an example of route guidance processing according to the fourth embodiment.

  As shown in FIG. 27, the user's daily sphere is composed of mesh regions. For example, when the user's daily sphere has a shape with many irregularities as shown in FIG. 27, the daily sphere frequently enters and exits depending on how the user moves. In such a case, it is determined whether or not a predetermined condition is satisfied for the daily area acquired from the daily area server 400 based on the area, shape, number of mesh regions to be configured, and the like. If not (or not satisfied), the daily routine area is determined with respect to the acquired daily area, and it is determined whether or not the current position of the user in step S138 of the route guidance process (FIG. 2) is within the daily area. Applies to

  As for the confirmation method of the daily life area, the mobile terminal 100 determines the daily life area by performing processing for extending the outline of the daily life area acquired from the daily life server 400 evenly by a predetermined distance. Various determination methods such as a method of determining a region obtained by uniformly increasing the number of mesh regions by a predetermined number at the periphery of the mesh region constituting the daily life area acquired from the server 400 as a daily life area can be employed.

  As shown in FIG. 27, the number of times the user enters and exits the everyday area by applying the everyday area to the determination as to whether or not the user's current position is within the everyday area in step S138 of the route guidance process (FIG. 2). In addition, the number of times of entering and exiting the daily routine area is reduced, so that frequent stop and start of route guidance and stop and start of reroute guidance can be avoided, and the annoyance felt by the user is further suppressed by the guidance function. can do.

E. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.
(E1) Modification 1:
In the above embodiment, the area where the route guidance system 10 does not perform part of the guidance function is the user's daily area, but is not limited thereto, and other areas are adopted as areas where the part of the guidance function is not performed. It is good. For example, if it is not the user's daily sphere but the user has previously confirmed the route traveled by a map, advertisement, etc., the route guidance process similar to the above embodiment is performed by setting this as a predetermined area. It can be performed. For example, an area in which the user has confirmed the route is set using the mobile terminal 100. Thereafter, the route guidance system 10 does not perform a part of the guidance function for the area set by the user, so that the route guidance process similar to the above embodiment can be realized.

  In addition, as a region where a part of the guidance function is not performed, for example, a region where a moving user can check the direction of the destination such as a building, a tower, or a signboard showing the destination is known in advance. The user sets the area using the mobile terminal 100, and the route guidance system 10 may not perform a part of the guidance function for this area. The specific processing performed by the user for the regions set by the user 100 can be realized by applying these regions to the region used for the determination in step S138 in the route guidance processing described with reference to FIG.

(E2) Modification 2:
As a second modification, the user's daily sphere may be divided into a plurality of areas, and the guidance function that the portable terminal 100 does not perform may differ depending on each area. FIG. 28 is an explanatory diagram showing an example of the second modification. As shown in the figure, the daily area is divided into two areas, the area close to the periphery is the first daily area, and the area close to the inside is the second daily area. The classification of the daily area may be performed by the mobile terminal 100. When the daily area is acquired from the daily area server 400, the daily area type (daily area) is transmitted before the daily area server 400 transmits to the mobile terminal 100. The daily sphere may be classified based on A, daily sphere B, etc. (see the second embodiment). In the present modification, the user starts moving from the departure place, and does not provide route guidance on the route or on the departure route in the second daily range. Then, when moving from the second daily area to the first daily area, when moving on the route, only the route display is started and the route voice guidance is not performed. On the other hand, when moving on a departure route, only reroute display is started and reroute voice guidance is not performed.

  Thereafter, when the user moves out of the first daily range, the route display and route voice guidance are performed when moving on the route, and the reroute display and reroute voice guidance are performed when moving on the departure route. Do. In this way, the process of dividing the daily area into a plurality of areas and changing the guidance function performed by each area may be applied when the daily area is included in a waypoint (passing point) or destination. . As for the way of classification, the user divides the daily sphere into areas that are more geographically detailed and areas that are not, or the areas where there are many roads or complicated areas and areas that are not so When there are a plurality of regions having different properties for the user in the daily sphere, such as categorizing, the daily sphere can be divided for each property. By doing so, the route guidance system 10 can appropriately perform only the guidance function suitable for the property, and more comfortable route guidance for the user can be performed.

(E3) Modification 3:
In the above-described embodiment, “not guiding” is described as not performing all of the guidance functions. However, the present invention is not limited to this. For example, route display and reroute display are performed, and route voice guidance and reroute voice guidance are performed. Some of the guidance functions may be performed, for example, no. Even if it does in this way, the troublesomeness which a user feels with a guidance function can be controlled.

(E4) Modification 4:
In the above embodiment, a mobile phone is adopted as the mobile terminal 100. However, the present invention is not limited to this, and the present invention is applicable to various mobile terminals that guide routes to the user, such as an in-vehicle navigation device, a PDA, and a tablet terminal. be able to.

  Regarding the correspondence relationship between the above-described embodiments and modifications and claims, the daily zone corresponds to the user area described in the claims, and the daily zone server 400 sets the user area described in the claims. Corresponds to the device. The daily area acquisition process performed by the CPU 112 corresponds to the function of the user area acquisition unit described in the claims.
