For these reasons, there are many telecommunications carriers (including free ones) that provide wireless LAN communications. Therefore, it is necessary to perform appropriate network settings each time it is used for wireless LAN communication. For example, ESSID (Extended Servo) compatible with the wireless LAN access point to be connected vice set identifier) and WEP (Wired Equivalent Privacy) key. Here, it is necessary to take the following procedure before network setting work. First, it is necessary to search for available wireless LAN access points at the current location. When multiple wireless LAN access points are found, it is necessary to select the optimal wireless LAN access point. And it is necessary to set ESSID and WEP key so that it can communicate with the selected wireless LAN access point.

FIG. 5 shows the relationship between the mobile terminal according to the first embodiment of the present invention and another mobile terminal. It is a figure which shows the ad hoc LAN comprised between.

First, the configuration of the wireless LAN shared system according to the first embodiment of the present invention will be described with reference to FIG. As shown in FIG. 3, the wireless LAN sharing system 300 includes mobile terminals 100a and 100b, a wireless LAN access point 301, a wireless LAN setting parameter database 302, a mobile terminal base station 303, a mobile terminal according to the first embodiment of the present invention, The management apparatus 200 is configured to manage the wireless LAN setting parameter database 302. Here, only one wireless AN access point 301 is depicted, but the number is not limited to one, and there may be multiple. Further, the wireless LAN setting parameter database 302 exists in a place where it can be connected to the Internet 304. Further, the above-described mobile terminals 100a and 100b are, for example, mobile phones.

Next, the wireless LAN connection flow in the wireless LAN shared system according to the first embodiment of the present invention and the subsequent ad hoc LAN configuration flow between mobile terminals will be described with reference to FIG. To do. First, the wireless LAN access point 301 intermittently broadcasts a beacon signal including information indicating the wireless LAN access point 301 (hereinafter also referred to as identification information) to the communicable range. Here, the identification information means information that can uniquely identify the wireless LAN access point 301. For example, the MAC (Media Access Control) address or ESSID of the wireless LAN access point 301 in the beacon signal in the IEEE 802.11 standard is used. Or unique identification information on the payload of the beacon signal. The payload means the data body that is transferred without the header part of the communication packet.

As shown in FIG. 4, portable terminal 100a receives a beacon signal including identification information from wireless LAN access point 301 (step S401). Here, the wireless LAN connection in the mobile terminal 100a will be described, but the same applies to the mobile terminal 100b. The mobile terminal 100a that has received the beacon signal including the identification information extracts the identification information from the received beacon signal, and the wireless LAN setting parameter in which the wireless LAN setting parameter for connecting the extracted identification information to the wireless LAN is stored. The data is transmitted to the management apparatus 200 that manages the database 302 via the mobile terminal base station 303 of the mobile terminal 100a itself (step S402). At this time, the extracted identification information is sent as user data. It may be transmitted as control data as well as location registration information. Also, identification information for identifying the mobile terminal 100a itself may be transmitted together with the extracted identification information. Here, the identification information for identifying the mobile terminal 100a itself may be, for example, a telephone number held by the mobile terminal 100a, an identification number assigned by the mobile terminal operator, or a MAC address when the mobile terminal 100a is converted to IP. It is done. In addition, as the wireless LAN setting parameters, for example, ESSID and WEP key in IEEE802.11 standard can be considered.

[0036] Based on the identification information of the wireless LAN access point 301 transmitted from the mobile terminal 100a, the management device 200 searches for the wireless LAN setting parameter from the wireless LAN setting parameter database 302, and the searched wireless LAN The setting parameter is transmitted to the mobile terminal 100a via the mobile terminal base station 303 (step S403). At this time, the management apparatus 200 may check whether or not the corresponding wireless LAN access point 301 can be used based on the identification information for identifying the mobile terminal 100a. If it is usable, a valid wireless LAN setting parameter may be transmitted, and if not usable, for example, an empty parameter may be transmitted to notify that it is unusable.

[0037] The portable terminal 100a sets the wireless LAN setting parameter received from the management apparatus 200 in itself. Then, the portable terminal 100a establishes communication with the wireless LAN access point 301 and starts communication. At this time, if necessary, the user of the portable terminal 100a may be notified of whether or not the setting can be made, and confirmation may be obtained. Note that when the provider providing the wireless LAN access point 301 provides it for a fee, the mobile terminal 100a sends the information on the start of use to the wireless LAN access point 301 via the mobile phone network or the wireless LAN network. It is transmitted to a charging device having a charging database (not shown) of the provider to be provided. As a result, the user information is registered in the charging database, and a charge for using the wireless LAN access point 301!

[0038] In this way, after the mobile terminal 100a is connected to the wireless LAN, the user power of the mobile terminal 100a is desired to configure an ad hoc closed LAN between the mobile terminal 100a and the mobile terminal 100b. The mobile terminal 100a sends a message including the identification information of the mobile terminal 100b (for example, the phone number of the mobile terminal 100b) via the mobile terminal base station 303 to the management device 2 Send to 00 (step S404).
