(About the base)
The “base” according to the present embodiment is a region, area, or the like determined in advance by a service provider that operates the management server 130, and includes one or more indoor facilities such as buildings and facilities. The base may be, for example, a base of a transportation facility such as a station, an airport, or a port, an area including the periphery thereof, or an area including one or more commercial facilities. The base may be one or more office buildings, a company base, or the like.

  In the present embodiment, the base includes a plurality of indoor facilities, and the indoor facilities include a plurality of floors. The floor includes a plurality of areas.

(About indoor facilities)
FIG. 2 is a diagram illustrating an image of an indoor facility according to an embodiment. In the example of FIG. 2, the indoor facility 200 is a building such as a building, for example, and has three floors, a floor A 110-1, a floor B 110-2, and a floor C 110-3. As described above, each indoor facility included in the base has one or more floors.

  A floor ID for identifying the floor is assigned to the floor. In the example of FIG. 2, floor ID “FLR10001” is assigned to floor A110-1, floor ID “FLR10002” is assigned to floor B110-2, and floor ID “FLR10003” is assigned to floor B110-3.

  Further, a wireless gateway 112 and a plurality of positioning devices 111 are installed on each floor. For example, on the floor A110-1, a wireless gateway 112-1 and a plurality of positioning devices 111-1a, 111-2a, 111-3a,... Are installed. The location where each positioning device 111 is installed is managed by three-dimensional coordinate information including the height direction. This is because the positioning devices 111 arranged on different floors cannot be distinguished only by the two-dimensional coordinate information.

  Preferably, the coordinate information indicating the position where the positioning device 111 is installed is managed by absolute coordinates such as latitude, longitude, and altitude, for example. Thereby, information of a plurality of indoor facilities can be managed in one coordinate system.

  Note that the coordinate information in the height direction may be, for example, information on the number of floors, but here, the coordinate information in the height direction is assumed to be, for example, altitude in meters. By using altitude as the coordinate information in the height direction, for example, an indoor facility having an irregular floor configuration such as a mezzanine floor or a plurality of indoor facilities with different floor heights can be Be able to manage.

  As shown in FIG. 2, the wireless gateways 112-1, 112-2 and 112-3 installed on each floor are connected to the management server 130 via, for example, an external gateway 113.

  In addition, on the floor A110-1, three positioning devices 111-1, 111-2, and 111-3 are installed as shown in FIG. 3, for example. In FIG. 3, the positioning device 111-1 outputs a signal including the position ID of the positioning device 111-1 to the communication range 301-1 of the positioning device 111-1. In addition, the positioning device 111-2 outputs a signal including the position ID of the positioning device 111-2 to the communication range 301-2 of the positioning device 111-2. Further, the positioning device 111-3 outputs a signal including the position ID of the positioning device 111-3 to the communication range 301-3 of the positioning device 111-3.

  In FIG. 3, for example, it is assumed that a user 115 possessing an information terminal 114 storing the base information of the base where the positioning device 111-1 is installed enters the floor A from the doorway 1. In this case, the information terminal 114 may specify the coordinate information of the current position of the information terminal 114 based on the position ID included in the signal output from the positioning device 111-1 and the base information stored in the information terminal 114. it can.

  The information terminal 114 is assumed to move out of the communication range 301-1 of the positioning device 111-1 and move in the direction of the positioning device 111-2. In this case, the information terminal 114 calculates the moving direction and the moving amount of the information terminal 114 using, for example, sensors such as an acceleration sensor and a geomagnetic sensor that the information terminal 114 has, thereby obtaining the position information of the information terminal 114. Can be specified. Note that various methods for calculating the movement amount of the information terminal 114 using a sensor are known, for example, as PDR (Pedestrian Dead Reckoning). In this embodiment, the PDR technique is used. Assume that the amount of movement of the information terminal 114 is calculated.

  Furthermore, when the information terminal 114 enters the communication range 301-2 of the positioning device 111-2, the location ID included in the signal output from the positioning device 111-2 and the base information stored in the information terminal 114 are The coordinate information of the current position of the information terminal 114 is specified. At this time, the information terminal 114 initializes information on the movement amount calculated by the PDR.

  Thus, in this embodiment, if the positioning device 111 is installed at least at the doorway of each floor, even if the positioning device 111 is not installed so as to cover the entire floor, the information terminal 114 The position information of the device itself can be acquired.

(About the area)
FIG. 4 is a diagram illustrating an image of an area according to an embodiment. In the example of FIG. 4A, the floor A110-1 is divided into a plurality of areas, and area IDs (AREA001 to AREA014) for identifying the areas are allocated to each area.

  In each area, for example, area types such as an aisle area 401, a shop area 402, a management area 403, a common area 404, an office area 405, and an off-limit area 406 are set.

  A passage area 401 indicates that a general user can freely pass therethrough. The shop area 402 indicates an area such as a shop that can be used by general users. The management area 403 is a management facility used by an administrator of an indoor facility, for example, and indicates that it is an area that a general user cannot enter.

  The shared area 404 is a shared space such as a toilet, for example, and indicates that it is an area that can be used by a general user, for example. The office area 405 indicates that the user who is permitted to use in advance can enter the area. The off-limit area 406 indicates that an ordinary user cannot enter due to, for example, construction.

  Of the above-described area types, the passage area 401, the shop area 402, and the common area 404 are examples of areas that can be used by general users. In addition, the management area 403, the office area 405, and the restricted entry area 406 are examples of areas where general users cannot pass.

  When the information terminal 114 calculates the current position information using the sensor of the information terminal 114, the area that the user 115 can pass is limited by using the above-described area type, for example, map matching or the like. Thus, the accuracy of the calculated position information can be improved.

  FIG. 4B shows an example of area types in the underground facility 410 such as an underpass. In underground facilities 410 such as underpasses, there are many cases where the area where people can pass is limited. In such a case, for example, as shown in FIG. 4B, the floor types of the floor of the underground facility 410 are managed as an accessible area 411 where people can pass and an inaccessible area 412 where people cannot pass. You may do it. As a result, calculation of position information by map matching or the like is facilitated, and the area type can be managed in binary.

  The indoor facility 200, the floor 110-1, the area, and the area type shown in FIGS. 2 to 4 are merely examples.
