The server 4 (position information acquisition device) is a server that manages the position information of the terminal 2. The server 4 communicates with the access point 3 via the network 5.
The network 5 is a network between the access point 3 and the server 4. For example, the network 5 is a network such as a LAN, a WAN (Wide Area Network), the Internet, or an NGN (Next Generation Network).

FIG. 2 is a sequence diagram showing a flow of processing in which the terminal 2 belongs to the access point 3.
First, the access point 3 periodically transmits a beacon signal notifying the existence of the wireless network of the own device to terminals around the own device (step S101). When the terminal 2 receives the beacon signal, the terminal 2 transmits a probe request to the transmission source access point 3 (step S102). By this probe request, the terminal 2 inquires of the access point 3 whether or not the network of the access point 3 is a network indicated by an ESS-ID (Service Set Identifier) set in its own device. When the ESS-ID notified by the probe request indicates the network of the own device, the access point 3 transmits a probe response to the terminal 2 (step S103). At this time, the access point 3 does not transmit a probe response to the terminal 2 when the ESS-ID notified by the probe request does not indicate its own network.

  Upon receiving the probe response, the terminal 2 performs an authentication process with the access point 3 (step S104). When the access point 3 authenticates itself, the terminal 2 transmits an association request to the access point 3 (step S105). When the access point 3 receives the association request, the access point 3 assigns an IP address or the like and accommodates the terminal 2 in its own network. When the access point 3 completes accommodation of the terminal 2, the access point 3 transmits an association response (step S106), and notifies the terminal 2 that the wireless attribution is completed. After the terminal 2 receives the association response, the terminal 2 can communicate with the upper network of the access point 3. The terminal 2 is accommodated in the access point 3 by executing a predetermined procedure shown in the above sequence.

In FIG. 10, the same processes as those in FIG. 2 are denoted by the same reference numerals as those in FIG. Further, the terminal 2 does not belong to the access point 3 at the time of starting the processing of FIG.
First, the control unit 34 of the access point 3 periodically transmits a beacon signal (a Beacon signal in the figure) to terminals in the vicinity of its own device, similarly to step S101 in FIG. 2 (steps S101-1 to S101-). 4). Then, the terminal 2 moves to the wireless communication range of the access point 3 and receives a beacon signal (step S101-4). When receiving the beacon signal, the control unit 22 of the terminal 2 transmits the probe request including the MAC address of the own device to the access point 3 (step S201).

  The access point 3 receives the probe request. The control unit 34 of the access point 3 acquires the MAC address of the transmission source terminal 2 from the received probe request (step S202). The control unit 34 refers to the position information table 331, and acquires the APID and position information values of its own device (step S203). The control unit 34 acquires time information indicating the time of the own device (step S204). The control unit 34 transmits the position information to the server 4 together with the MAC address of the terminal 2, the APID of the own device, and time information (step S205). When the position information is transmitted to the server 4, the control unit 34 performs steps S <b> 103 to S <b> 106 and accommodates the terminal 2 in its own device.

  On the other hand, in the server 4 that has received the position information in step S205, the position information acquisition unit 44 registers the position information (step S206). Specifically, the position information acquisition unit 44 refers to the terminal information table 421 and selects a terminal information record having the terminal ID MAC address of the terminal 2 received together with the position information as the value of the terminal ID. The position information acquisition unit 44 acquires the value of the user ID from the selected terminal information record. The position information acquisition unit 44 uses the acquired position information as terminal position information, and generates a user position information record having a user ID, time information, and terminal position information values. The position information acquisition unit 44 registers the generated user position information record in the user position information table 431 of the user indicated by the user ID.

  In the position information acquisition system 1 of the first embodiment configured as described above, the access point 3 transmits the position information of its own device to the server 4 as the position information of the terminal 2 at the timing when the probe request of the terminal 2 is received. To do. By transmitting the position information at the above timing, the position information acquisition system 1 can acquire the position information without waiting for completion of belonging to the access point 3 of the terminal 2. Therefore, the position information acquisition system 1 of the embodiment can acquire the position information of the terminal 2 more efficiently.

  Further, the access point 3 transmits the location information of the own device to the server 4 as the location information of the terminal 2 that requests attribution to the own device. This makes it possible to acquire the position information of the terminal 2 that does not have a GPS.

FIG. 11 is a diagram illustrating an example of use of the position information acquisition system 1 according to the first embodiment.
In FIG. 11, reference numerals 3-1 to 3-5 represent a plurality of access points 3. Reference numeral 7-1 denotes a communication range of the access point 3-1. Reference numeral 7-2 denotes a communication range of the access point 3-2. Similarly, reference numerals 7-3 to 7-5 are communication ranges of the access points 3-3 to 3-5, respectively. Reference numerals 2-1-1 to 2-1-3 are terminals 2 positioned within the communication range 7-1. Reference numerals 2-2-1 and 2-2-2 are terminals 2 located within the communication range 7-2. Similarly, reference numerals 2-3, 2-4, and 2-5 are terminals 2 located within the communication ranges 7-3, 7-4, and 7-5, respectively.

  In FIG. 11, the terminals 2-1-1 to 2-1-3 are located in a building number 8. In this case, the terminals 2-1-1 to 2-1-3 transmit a probe request to the access point 3-1 installed in the same building 8. The access point 3-1 transmits the position information of its own device to the server 4 as the position information of the terminals 2-1-1 to 2-1-3 that transmitted the probe request. Thus, in the position information acquisition system 1 of this embodiment, the position information of the terminal 2 located indoors can be acquired more reliably.

  In addition, when the position information is acquired using GPS, an application for using GPS is generally installed in the terminal 2. However, in the present embodiment, the terminal 2 does not need to acquire the position information of the own device, and does not need a GPS application. Furthermore, the terminal 2 does not need to have a GPS function. That is, in the position information acquisition system 1 of the embodiment, position information can be acquired for any terminal as long as it is a terminal wirelessly belonging to the access point 3.

  The terminals 2-2, 1-2-2 and 2-3-2-5 are located outdoors with respect to the terminals 2-1-1-2-1-3. The terminals 2-2-1 and 2-2-2 transmit a probe request to the access point 3-2. The access point 3-2 transmits the position information of its own device to the server 4 as the position information of the terminals 2-2-1 and 2-2-2 that transmitted the probe request. Similarly, the terminals 2-3 to 2-5 transmit probe requests to the access points 3-3 to 3-5. The access points 3-3 to 3-5 transmit the position information of the own device to the server 4 as the position information of the terminals 2-3 to 2-5 that transmitted the probe request.

  As described above, in this embodiment, the access point 3 transmits the position information at the timing when the probe request is received from the terminal 2. Therefore, the time required to acquire the position information is shortened, and the possibility that the position information of the terminal 2 can be acquired even when the stay time in the communication range is short is increased. For example, it is possible to acquire position information more reliably for terminals that move in different communication ranges of communication ranges 7-3 to 7-5, such as terminals 2-3 to 2-5 in FIG. Become.

The control unit 22a transmits the probe request including the position information and the MAC address of the own device to the access point 3a (step S302).

  The access point 3a receives the probe request. The control unit 34a of the access point 3a acquires the MAC address and position information of the transmission source terminal 2a from the received probe request (step S303). The control unit 34a refers to the position information table 331 and acquires the value of the APID of the own device (step S304). The control unit 34a acquires time information indicating the time of the own device (step S305). The control unit 34a transmits the position information to the server 4 together with the MAC address of the terminal 2a, the APID of the own device, and time information (step S306). When the position information is transmitted to the server 4, the control unit 34 a performs steps S <b> 103 to S <b> 106 and accommodates the terminal 2 a in its own device.
