  Next, the operation of the embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a flowchart showing the operation of the embodiment of the present invention.

  Description will be made assuming that a user (for example, a parent and a child) possessing the user portable terminals 10 and 20 enters a department store or the like where a wireless LAN system is installed. When entering the communication area of the wireless access point 30 installed in the store, the user requests an IP address from the user portable terminals 10 and 20 to the wireless LAN management server 40 via the wireless access point 30. At this time, the connection information to the wireless access point 30 is acquired by the user portable terminals 10 and 20 from the wireless LAN management server 40 in advance and stored in a storage unit (not shown), for example. Also, the user recognizes that the user has entered the communication area of the wireless access point 30, for example, when the user portable terminals 10 and 20 detect and display radio waves from the wireless access point 30. In the following description, an operation in the case where a child holds the user portable terminal 10 and a parent owns the user portable terminal 20 and the parent user portable terminal 20 issues a search request when the child is lost will be described. (Step A1 in FIG. 4).

  The control unit 41 of the wireless LAN management server 40 assigns different IP addresses to the user portable terminals 10 and 20 and registers them in the portable terminal management database 421 together with the connection start time. This registration is performed for each of the user portable terminals 10 and 20. As for the connection start time, the control unit 41 obtains the current time from a clock unit (not shown) and registers it as the connection start time to the wireless LAN system. And the control part 41 transmits an IP address to the user portable terminals 10 and 20, respectively, and the user portable terminals 10 and 20 store the received IP address in a storage part (not shown) (step A2).

(Step A3). The control unit 41 of the wireless LAN management server 40 registers each received feature information in the feature information database 422 in association with the IP address (step A4).

  The process for registering the feature information from the user portable terminals 10 and 20 to the wireless LAN management server 40 has been described above. Next, the search process will be described.

  The search request can be made from either of the user portable terminals 10 and 20, but here, when a parent requests a search for a lost child (the parent user portable terminal 20 searches for a child user portable terminal 10). Will be described as an example.

  When the user (parent) accesses the wireless LAN management server 40 from the user portable terminal 20 and inputs the feature information of the child as the search condition, the user portable terminal 20 attaches the IP address of the own terminal to the input feature information. Transmit to the wireless LAN management server 40. At this time, the child feature information input by the user (parent) may be a part or all of the feature information registered in the feature information database 422. The IP address is acquired from a storage unit (not shown) of the user portable terminal 20 (step A5). The control unit 41 of the wireless LAN management server 40 searches for feature information registered in the feature information database 422 based on the feature information received from the user portable terminal 20 (step A6). Then, the control unit 41 transmits the search result to the user portable terminal 20. At this time, if there is no user that matches the received search condition (feature information input by the parent), the control unit 41 notifies that fact. If there is a user that matches the received search condition, the control unit 41 acquires the feature information of the corresponding user registered in the feature information database 422 and includes it in the search result notification (step A7).

  The user portable terminal 20 receives and displays the search result from the wireless LAN management server 40 (step A8). The user (parent) determines whether there is a user who matches the feature information as the search condition by looking at the displayed search result. When there is a matched user, feature information of all the matched users, a user selection field, and a contact request button are displayed as search result screen information. When the user (parent) selects his / her child in the user selection field on the screen and presses the contact request button on the screen, the user portable terminal 20 transmits a contact request to the wireless LAN management server 40. At this time, the characteristic information of the selected child and the IP address of the user portable terminal 20 are transmitted to the wireless LAN management server 40 (steps A9 and A10). The control unit 41 of the wireless LAN management server 40 connects the child user portable terminal 10 and the parent user portable terminal 20, and the parent and child user portable terminals 10, 20 enter a call state. At this time, the control unit 41 acquires the IP address of the child user portable terminal 10 from the feature information database 422 based on the feature information of the selected child (step A11).

  In the embodiment described above, the embodiment includes only the user portable terminal and the wireless LAN system, and does not pass through an external network such as a mobile phone base station or the Internet. For this reason, it can be used even in places with poor radio wave conditions such as the underground floor of a building, and the effect of not incurring a communication charge burden for the user can be obtained.

  Also, an IP address is assigned to each user portable terminal in the wireless LAN area, and user characteristic information is registered in association with the IP address. As a result, there is an effect that a user search based on the feature information becomes possible in the wireless LAN area.

  Next, another embodiment of the present invention will be described.

Check for existence. Specifically, the control unit 41 counts a predetermined time with a timer unit (not shown), and transmits a packet (for example, a ping packet) for connection confirmation to each user portable terminal 10 and 20 when the predetermined time is reached. The user portable terminals 10 and 20 that have received the packet for connection confirmation transmit a response packet (for example, a pong packet) together with their own IP address. Then, the control unit 41 monitors whether there is a response from each user portable terminal 10, 20. If there is a response, the control unit 41 determines that the user is within the wireless LAN area, and if there is no response, determines that the user has moved outside the wireless LAN area. (Steps B13 and B14).

  For the user portable terminals 10 and 20 that have not responded, the control unit 41 refers to the feature information database 422 to check whether the search result notification destination IP address is registered (step B14 → step B15). If the search result notification destination IP address is not registered, the control unit 41 deletes the registered data of the user portable terminals 10 and 20 that have not responded from the portable terminal management database 421 and the feature information database 422 (step S41). B15 → step B17). If registered, the control unit 41 notifies the user portable terminals 10 and 20 of the registered search result notification destination IP address that the search partner who previously notified the search result has moved out of the wireless LAN area. To do. Here, “previous” means the period from when the user portable terminal 10 or 20 enters the wireless LAN area until the present (step B15 → step B16). After the notification, the control unit 41 deletes the registered data of the user portable terminals 10 and 20 that did not respond from the portable terminal management database 421 and the feature information database 422 (step B16 → step B17). The user portable terminal 20 receives and displays that the search partner (user portable terminal 10) that has received the search result has moved out of the wireless LAN area (step B18).

  According to the other embodiment described above, in addition to the effect of the above-described embodiment, the effect that it is possible to grasp that the search partner who has received the previous search result has moved out of the wireless LAN area is further obtained.
