(Step S5). In addition, the information providing unit 12 of the server 1 extracts access point information even for an access point with a high priority within the range of the free capacity of the terminal 2 included in the access point information acquisition request. Note that the priority is determined by, for example, the order of access points used frequently by the user of the terminal 2 or the date and time when the user of the terminal 2 used the new access point.

  When the access point information is extracted, the information providing unit 12 of the server 1 transmits the extracted access point information to the terminal 2 (step S6). If the access point for acquiring access point information is not specified in the access point information acquisition request, the information providing unit 12 of the server 1 transmits only the access point information extracted as an access point with a high priority.

  When the access point information is received, the access point information management unit 21 of the terminal 2 stores the received access point information in the storage device 24 (step S7).

  Next, processing when the terminal 2 is used on the go will be described.

  FIG. 6 is a block diagram showing a configuration of a communication system when the terminal is used on the go.

  As shown in FIG. 6, the communication system when the terminal is used on the go has a PC 2, an access point 4, and an RF (Radio Frequency) tag 5.

  The access point 4 has a relay function for the terminal 2 to access a network such as the Internet. The access point 4 is connected to the terminal 2 via a wireless LAN, and is connected to a network such as the Internet via a wired LAN. The access point 4 converts the wireless LAN packet received from the terminal 2 into a wired LAN packet and transmits it to a network such as the Internet.

  The communication control unit 22 of the terminal 2 carries the access point information stored in the storage device 24 in response to an instruction from the user when the user is connected to the access point that is carried by the user and installed in the place of going out. indicate. The user can select an access point to be displayed by specifying a condition such as a keyword. The communication control unit 22 of the terminal 2 displays a list of access point information for access points that meet the conditions specified by the user. When the access point to be connected is selected by the user, the communication control unit 22 of the terminal 2 requests connection to the access point based on the setting information of the selected access point, and the Internet or the like via the access point. Connect to your network.

  When connected to the access point, the access point information updating unit 23 of the terminal 2 records the date and time of connection to the access point and the user name of the own device in the access record information of the access point information stored in the storage device 34.

  Further, the access point information updating unit 23 of the terminal 2 reads the coordinate information of the access point 4 from the RF tag 5 attached to the connected access point 4 and uses it as the coordinate information of the access point information stored in the storage device 24. Record.

  When the access point information stored in the storage device 24 is displayed, the communication control unit 22 of the terminal 2 displays a map, and the position of the access point from which the own device acquires coordinate information on the map. You may make it represent. The communication control unit 22 of the terminal 2 calculates the position of the access point on the displayed map from the longitude, latitude, and altitude information of each access point, and displays the position of the access point on the map. The map may be a planar map or a three-dimensional map. When the access point information is displayed on the three-dimensional map, the communication control unit 22 of the terminal 2 includes the altitude information of the access point and the altitude of the access point on the displayed map from the height of the building. The location including the altitude of the access point is displayed on the map. By displaying the position of the access point on the three-dimensional map, the user can more precisely determine the position of the access point in the building when the access point to be connected exists in the building. Can be recognized.

  The function of displaying a map may be realized by linking with general-purpose map software.

  Next, processing when the terminal 2 updates the access point information of the server 1 in the communication system shown in FIG. 1 will be described.

  FIG. 8 is a diagram showing a sequence between the terminal 2 and the server 1 when the terminal 2 updates the access point information of the server 1 in the communication system shown in FIG.

  When the terminal 2 is connected to the server 1 by a user after connecting to an access point installed outside, the terminal 2 records on the server 1 the usage record information updated by the own device or the coordinate information acquired from the RF tag. Update the access point information.

  When connecting to the server 1, the access point information updating unit 23 of the terminal 2 first transmits an access point information update request indicating a request for updating the access point information of the server 1 to the server 1 (step S11). The access point information update request includes usage record information and coordinate information stored in the storage device 24.

  When the access point information update request is received from the access point information update unit 23 of the terminal 2, the information management unit 11 of the server 1 extracts the usage record information and the coordinate information from the received access point information update request and stores them in the storage device 13. The stored access point information is updated (step S12).

  When the access point information is updated, the information management unit 11 of the server 1 transmits an access point information update response indicating that the update of the access point information is completed to the terminal 2 (step S13).

  The server 1 can provide updated access point information to terminals other than the terminal 2 by updating the access point information in response to a request from the terminal 2. When the terminal other than the terminal 2 acquires the coordinate information of the access point updated by the terminal 2, the terminal updates the coordinate information stored in the storage device of the own device to the acquired coordinate information. Thereby, terminals other than the terminal 2 can display the position on the map of an own apparatus also about the access point which has not connected.

  Hereinafter, an example of access point information stored in the terminals 2 and 3 will be described.

  FIG. 9 shows an example of access point information provided by the server 1 to the terminal 2 when the terminal 2 whose user is U2 requests the server 1 for access point information whose area is Osaka.

  When receiving an access point information acquisition request from the terminal 2, the server 1 first extracts access points whose area is Osaka from the access points shown in FIG. Next, the server 1 extracts an access point that has been used by the user U2 in the past as an access point having a high priority, although the area is Tokyo. As shown in FIG. 9, the server 1 stores access point information of an access point whose area is Osaka, and access point information of an access point whose area is Tokyo but the user U2 has used in the past. Provided to the terminal 2.

  When the terminal 2 is carried by the user and connected to an access point installed outside, the terminal 2 displays the access point information stored in the own device in accordance with an instruction from the user. The user can select an access point to be displayed by specifying a condition such as a keyword. FIG. 10 shows a display example when an access point whose station name is FF is selected. As shown in FIG. 10, only the access point information of the access point whose station name is FF among the access point information shown in FIG. 9 is displayed.

  FIG. 11 shows an example of access point information provided by the server 1 to the terminal 3 when the terminal 3 whose user is U3 requests the server 1 for access point information whose area is Osaka or Fukuoka. As shown in FIG. 11, the user can also specify a plurality of access point conditions for obtaining access point information. In addition, the access point conditions for acquiring the access point information may be conditions other than the area, such as a business name, a station name, a building name, a business type, and an address.

  FIG. 12 shows a display example when an access point whose area is Fukuoka is selected as the access point information displayed on the terminal 3. As shown in FIG. 12, only the access point information of the access point whose area is Fukuoka is displayed among the access point information shown in FIG.

  Note that the size of the free capacity that can store the access point information included in the access point information acquisition request differs for each terminal. Therefore, even if the same user requests access point information from different terminals, the access point information provided from the server is different. Thereby, the user can acquire access point information of an appropriate size according to the application.

  As described above, according to the present embodiment, a terminal accessing a public wireless LAN requests necessary access point information from a server that centrally manages access point information. At this time, the server automatically extracts a high-priority access point from the user under individual conditions, and provides the extracted access point information to the requested terminal. As a result, a terminal that accesses the public wireless LAN can acquire information on an access point appropriate for the terminal, so that necessary access point information can be efficiently stored in its own device. The access point can be preferably accessed using the information.

  In addition, the server can select an access point in descending order of use frequency by the user of the terminal, so that the terminal can store an access point that is likely to be used by the user.

  In addition, since the server selects the access points in the order of the date and time used in the past by the user of the terminal, the terminal may store the access points that are likely to be used by the user in the terminal. it can.

  In addition, by pasting the RF tag storing the coordinate information of the access point on the access point, the terminal that has read the coordinate information can display a map representing the position of the access point, and the user Convenience can be improved.

  Also, by recording altitude information in the coordinate information of the access point of the RF tag and making the map showing the access point information into a three-dimensional map, the user can access It is possible to recognize in more detail where the access point is located in the building.

  Even if the terminal that has acquired the coordinate information of the access point registers the coordinate information in the access point information of the server and shares the information with other terminals, the terminal has never used the access point. A map showing the location of the access point can be displayed.
