<Operation of this wireless communication system>
The operation of this wireless communication system will be described.

  FIG. 5 shows an example of a network to which the present wireless LAN access point and the present wireless communication terminal are applied.

  In FIG. 5, a wireless LAN access point (AP1) 502, a wireless LAN access point (AP2) 504, a wireless communication terminal 506, a router 508, and a name server 512 are depicted. The wireless LAN access points 502 and 504 are connected to the router 508 by wire. The router 508 is connected to the communication network 510. The communication network 510 includes the Internet. The wireless communication terminal 506 is wirelessly connected to a base station (not shown), and the base station is connected to the communication network 514. The communication network 514 includes a cellular communication network. The name server 512 is connected to the communication networks 510 and 514.

  The router 508 implements UPNP (Universal Plug and Play). The router 508 connected to the network functions with no complicated operation or setting work.

  In the present embodiment, URL (Uniform Resource Locator) as URI information is embedded in the wireless LAN access points 502 and 504 in advance before shipment. In other words, URLs are stored in advance in the wireless LAN access points 502 and 504. A sticker on which a two-dimensional code (2D code) in which URL information set in advance before shipment is recorded is attached to the wireless LAN access point 502. The two-dimensional code includes a two-dimensional barcode and a QR code (QR code: Quick Response code). Communication ports that can access the wireless LAN access points 502 and 504 are also uniquely set.

  FIG. 6 shows the operation of the wireless communication system.

  Hereinafter, a method in which the wireless communication terminal 506 performs settings related to the wireless LAN with respect to the wireless LAN access point 502 will be described.

  After purchasing the wireless LAN access point 502, the user connects to the home router (step S602). For example, the wired communication frame receiving unit 213 and the wired communication frame transmitting unit 220 are connected to the wired network.

  The wireless LAN access point 502 is assigned a local address from the router 508 by DHCP (Dynamic Host Configuration Protocol) (step S604). The wireless LAN access point 502 is connected to a local network under the router 508. For example, the wired communication frame transmission unit 220 is assigned a local address from the router 508 by accessing the router 508 by DHCP.

  The wireless LAN access point 502 makes a request for registering the URL set in the wireless LAN access point 502 in the name server 512 via the router 508 (step S606). The name server 512 includes a dynamic domain name system (DNS) server. DDNS is a technology that dynamically updates the DNS database. DDNS has been standardized as RFC2136 by the IETF. For example, the URL registration request frame creation unit 219 acquires the URL of the wireless LAN access point 502 stored in the URL management unit 218. Then, the URL registration request frame creation unit 219 creates a URL registration request frame including the URL and transmits the URL registration request frame via the wired communication frame transmission unit 220. The URL registration request frame is received by the name server 512 via the router 508. The name server 512 registers the URL included in the URL registration request frame transmitted by the wireless LAN access point 502. The name server 512 creates a table in which the URL is associated with the global address assigned to the wireless LAN to which the wireless LAN access point 502 belongs.

  FIG. 7 shows an example of a table created by the name server 512.

  For example, the URL of the wireless LAN access point 502 is “http: // apkantan / settei1”, and the global address of the router 508 is “192.10.1.1”. The name server 512 creates a table as shown in FIG. As the table is created by the name server 512, the wireless LAN access point 502 is connected to a wired network.

  The user activates the camera of the wireless communication terminal 506 (step S608). For example, the URI information receiving unit 406 is activated by the user.

  The wireless communication terminal 506 reads the two-dimensional code attached to the wireless LAN access point 502 (step S610). By reading the two-dimensional code pasted on the wireless LAN access point 502, the wireless communication terminal 506 can acquire the URL of the wireless LAN access point 502. For example, the URI information receiving unit 406 reads a two-dimensional code attached to the wireless LAN access point 502. Then, the URI information receiving unit 406 inputs the URI of the wireless LAN access point 502 obtained by reading the two-dimensional code to the URI management unit 407 of the connection destination AP.

  The wireless communication terminal 506 creates wireless LAN setting information to be set in the wireless LAN access point 502 (step S612). For example, the wireless communication terminal 506 creates the wireless LAN setting information with the acquisition of the URL of the wireless LAN access point 502 as a trigger. The wireless LAN setting information includes an SSID, an encryption communication key, a frequency channel, a beacon period, a random backoff parameter for setting a transmission waiting time, and the like. For example, the wireless LAN setting information creation unit 408 creates wireless LAN setting information and inputs it to the wireless LAN setting information frame creation unit 409.

  The wireless communication terminal 506 inquires of the name server 512 about the global address corresponding to the URL acquired by reading the two-dimensional code through the cellular interface (step S614). The global address inquiry frame creation unit 412 of the connection destination AP acquires the URL of the wireless LAN access point from the URI management unit 407 of the connection destination AP. Then, the global address inquiry frame creation unit 412 of the connection destination AP generates a global address inquiry frame for inquiring about the global address of the wireless LAN access point 502 corresponding to the URL of the wireless LAN access point acquired from the URI management unit 407 of the connection destination AP. It is created and transmitted via the cellular transmitter 413. The global address inquiry frame is received by the name server 512 via the communication network 514. The name server 512 transmits a global address response frame including a global address corresponding to the URL as a response to the global address inquiry frame transmitted by the wireless communication terminal 506. The global address response frame is transmitted to the wireless communication terminal 506 via the communication network 514.

  The wireless communication terminal 506 acquires the global address of the wireless LAN access point 502 as a response to the inquiry in step 614 (step S616). The global address is a global address assigned to the local network to which the wireless LAN access point 502 belongs. For example, the global address response frame transmitted by the name server 512 is received by the cellular reception unit 411. The cellular reception unit 411 inputs the global address response frame to the URI management unit 407 of the connection destination AP.

  The wireless LAN access point 502 broadcasts a beacon accompanied by the AP identifier of the wireless LAN access point 502 through the wireless LAN interface (step S618). For example, the AP identifier notification frame creation unit 206 acquires the AP identifier by the AP identifier management unit 205. Then, the AP identifier notification frame creation unit 206 creates an AP identifier notification frame including the AP identifier and transmits it from the wireless LAN frame transmission unit 208. The wireless LAN access point 502 may weaken the beacon transmission power. For example, the transmission power control unit 207 controls the transmission power of the AP identifier notification frame to be weak. By reducing the transmission power, the beacon arrival area can be narrowed, so that the AP identifier can be prevented from leaking outside the home. In other words, only the user at home can recognize the AP identifier. At this time, the wireless LAN access point 502 has no setting items for each wireless LAN. Therefore, each value in the beacon to be described in IEEE802.11 such as SSID may be left unset, or an arbitrary value may be set. The wireless communication terminal 506 receives the beacon transmitted by the wireless LAN access point 502. For example, the wireless LAN frame reception unit 401 receives a beacon and inputs it to the beacon analysis unit 402. The beacon analysis unit 402 inputs the AP identifier included in the beacon to the wireless LAN setting information frame creation unit 409.

  The wireless communication terminal 506 transmits a probe request frame including the identifier (STA identifier) of the wireless communication terminal 506 via the wireless LAN interface (step S620). For example, the STA identifier notification frame creation unit 404 acquires the STA identifier by the STA identifier management unit 403. Then, the STA identifier notification frame creation unit 404 creates a probe request frame including the STA identifier and transmits it from the wireless LAN frame transmission unit 405. The wireless LAN access point 502 receives the probe request frame transmitted by the wireless communication terminal 506 and acquires the STA identifier. For example, the probe request frame transmitted by the wireless communication terminal 506 is received by the wireless LAN frame receiving unit 201. The wireless LAN frame reception unit 201 inputs the probe request frame to the reception RSSI analysis unit 202. The received RSSI analysis unit 202 inputs a valid probe request frame to the STA identifier analysis unit 203. The STA identifier analysis unit 203 inputs the reception time of the valid probe request frame to the reception information validity confirmation unit 211 together with the STA identifier included in the valid probe request frame. When the wireless LAN access point 502 acquires the STA identifier, the wireless LAN access point 502 can be made to recognize the wireless communication terminal that issues a command regarding the setting of the wireless LAN.

  The wireless LAN access point 502 may validate only probe request frames received from the wireless communication terminal 506 that have a predetermined reception strength or higher. By enabling only probe request frames with a predetermined reception strength or higher, even if a malicious one transmits a probe request frame from outside the home, the probe request frame has low reception strength. Since the reception strength is low, the wireless LAN access point 502 does not validate the probe request frame. Therefore, it can be avoided that a malicious user impersonates an authorized user from outside the home and causes the wireless LAN access point 502 to recognize a wireless communication terminal that issues a command related to wireless LAN setting. As described above, the identifier is exchanged between the wireless LAN access point 502 and the wireless communication terminal 506.

  After the wireless communication terminal 506 acquires the global address in step S616, the wireless LAN setting information can be transmitted by designating the global address and the communication port number for the wireless LAN access point 502 as the transmission destination. However, there is a problem when the wireless LAN setting information is transmitted by designating the global address acquired by the name server 512 and the communication port number for the wireless LAN access point 502 as the transmission destination. The problem is that the wireless LAN access point 502 may accept wireless LAN setting information from an arbitrary wireless communication terminal 506. When the wireless LAN access point 502 accepts wireless LAN setting information from an arbitrary wireless communication terminal 506, if the malicious user is included in the arbitrary wireless communication terminal 506, a wireless LAN is transmitted by the malicious user. The setting of the access point 502 may be changed. The URL of the wireless LAN access point 502 is recorded in a two-dimensional code before shipment and pasted on the wireless LAN access point 502. Therefore, the URL of the wireless LAN access point 502 is open information.

  Therefore, in the present embodiment, an identifier is exchanged between the wireless LAN access point 502 and the wireless communication terminal 506, thereby avoiding the problem that the setting of the wireless LAN access point 502 is changed by a malicious user. .

  The wireless communication terminal 506 attaches the wireless LAN setting information, the STA identifier, and the AP identifier to the wireless frame through the cellular interface, and transmits the global address of the router 508 as the destination (step S622). For example, the wireless LAN setting information frame creation unit 409 receives the global address, the STA identifier, and the wireless LAN access point from the URI management unit 407, STA identifier management unit 403, and cellular communication identifier management unit 410 of the connection destination AP, respectively. Get the cellular identifier. Then, the wireless LAN setting information frame creation unit 409 includes wireless LAN setting information including the wireless LAN setting information input by the wireless LAN setting information creation unit 408, the AP identifier input by the beacon analysis unit 402, and the STA identifier. A frame is created and transmitted by the cellular transmitter 413 with the global address as the destination and the cellular identifier as the transmission source. The wireless LAN setting information frame is transferred to the router 508 via the communication networks 514 and 510.

  The router 508 recognizes the port number designated between the router 508 and the wireless LAN access point 502 based on the wireless LAN setting information frame transmitted by the wireless communication terminal 506 in step S622. Then, the router 508 transfers the wireless frame to the wireless LAN access point 502 by the port forward function (steps S624 and S626). The port forward function is a function for distributing communication partners according to port numbers.

  The wireless LAN access point 502 confirms the validity of the frame transferred by the router 508 (step S628). For example, the wireless LAN access point 502 confirms the validity of the AP identifier and the validity of the transmission source. For example, the wireless LAN access point 502 confirms whether the AP identifier included in the wireless LAN setting information frame received from the router 508 matches the AP identifier of the wireless LAN access point 502, thereby validating the AP identifier. to decide. The wireless LAN access point 502 compares the STA identifier included in the wireless LAN setting information frame with the STA identifier included in the probe request frame that has already been received via the wireless LAN interface, thereby confirming the validity of the transmission source. Check. When the STA identifier included in the wireless LAN setting information frame matches the STA identifier included in the probe request frame, the wireless LAN access point 502 determines that the transmission source of the wireless LAN setting information frame is valid. If the STA identifier included in the wireless LAN setting information frame does not match the STA identifier included in the probe request frame, the wireless LAN access point 502 does not determine that the transmission source of the wireless LAN setting information frame is valid. When it is not possible to determine that the transmission source of the wireless LAN setting information frame is valid, the wireless LAN setting information frame may be discarded.

  For example, the wireless LAN setting information frame transferred by the router 508 is received by the wired communication frame receiving unit 213 and input to the wireless LAN setting information frame analyzing unit 209. The wireless LAN setting information frame analysis unit 209 inputs the STA identifier, AP identifier, and wireless LAN setting information included in the wireless LAN setting information frame to the reception information validity checking unit 211. The received information validity confirmation unit 211 acquires the AP identifier by the AP identifier management unit 205 and confirms whether the AP identifier matches the AP identifier input by the wireless LAN setting information frame analysis unit 209. Also, the reception information validity confirmation unit 211 confirms whether the STA identifier input by the STA identifier analysis unit 203 matches the STA identifier input by the radio frame setting information frame analysis unit 209. The reception information validity confirmation unit 211 may confirm whether the wireless LAN setting information frame is received within a predetermined period from the probe request reception time input by the STA identifier analysis unit 203. By enabling only the wireless LAN setting information received from the wired network within a predetermined time after the wireless LAN access point 502 receives the probe request frame via the wireless LAN interface, the wireless LAN access point 502 It can be recognized that the wireless communication terminal that is the transmission source of the frame including the wireless LAN setting information is certainly at home at this time.

  When the router 508 transfers the wireless LAN setting information frame to the wireless LAN access point 504 that is not intended by the wireless communication terminal 506, the AP identifier included in the wireless LAN setting information frame is the AP identifier of the wireless LAN access point 504. Different. When the AP identifiers are different, the wireless LAN access point 504 determines that the wireless LAN setting information frame is not transmitted to the wireless LAN access point 504. If the wireless LAN access point 504 determines that the wireless LAN setting information frame is not transmitted to the wireless LAN access point 504, the wireless LAN access point 504 broadcasts the wireless LAN setting information frame to the wired network side. For example, if the AP identifier included in the wireless LAN setting information frame is different from the AP identifier of the wireless LAN access point 504, the reception information validity confirmation unit 211 sends the wireless LAN setting information frame to the wired communication frame transmission unit 220. input. The wired communication frame transmission unit 220 broadcasts the wireless LAN setting information frame input by the reception information validity checking unit 211 to the wired network. By broadcasting the wireless LAN setting information frame, the wireless LAN access point 502 can receive the wireless LAN setting information frame.

  When the wireless LAN access point confirms the validity of the destination of the wireless LAN setting information frame transferred by the router 508, the router 508 forwards the frame to the wireless LAN access point not intended by the wireless communication terminal 506 by the port forward function. Even in this case, the wireless LAN access point can recognize that the frame is not addressed to the wireless LAN access point. Therefore, it is possible to solve the problem that occurs when the router 508 distributes the frame received by the port forward function to the wireless LAN access point. In this embodiment, since the port number is uniquely set, when there are a plurality of wireless LAN access points, the router 508 transfers to a wireless LAN access point that is not the wireless LAN access point intended by the wireless communication terminal 506. there's a possibility that. For example, the router 508 may transfer to the wireless LAN access point 504 instead of the wireless LAN access point 502 intended by the wireless communication terminal 506. Even when the router 508 forwards the frame to the wireless LAN access point 504, the wireless LAN access point 504 can confirm the validity of the forwarded frame and confirm that the frame is not addressed to the wireless LAN access point 504. Can be recognized.

  If the validity of the frame is confirmed in step S628 and it is determined that the wireless LAN setting information is reliable, the wireless LAN access point 502 sets the wireless LAN setting information (step S630). For example, the reception information validity confirmation unit 211 confirms the validity of the information based on information included in the wireless LAN setting information frame. If it is determined as a result of the confirmation, the reception information validity confirmation unit 211 sends a wireless LAN setting information and a setting command for setting the wireless LAN setting information to the wireless LAN access point 502 as a wireless LAN parameter setting. Input to the unit 212. The wireless LAN parameter setting unit 212 sets the wireless LAN setting information according to the setting command input by the reception information validity checking unit 211.

  The wireless communication terminal 506 and the wireless LAN access point 502 are connected by the wireless LAN (step S632).

  The process of step S612 in FIG. 6 may be performed after step S616.

  In step S628, the validity of the transmission source of the wireless LAN setting information may be confirmed as follows. In the wireless LAN access point 502, an identifier used when the wireless communication terminal 506 communicates via the cellular interface is registered in advance. Then, the wireless communication terminal 506 transmits an identifier used in cellular communication together with the wireless LAN setting information. When the wireless LAN access point 502 receives the wireless LAN setting information from the wired network, the wireless LAN access point 502 determines whether the identifier transmitted together with the wireless LAN setting information matches the identifier used in the cellular communication set in advance. From this determination, the validity of the wireless LAN setting information can be confirmed.

  In the present embodiment, the case where the wireless LAN access point notifies the wireless communication terminal 506 of the URL of the wireless LAN access point via the two-dimensional code has been described. . For example, the wireless LAN access point may notify the URL of the wireless LAN access point by a short-range wireless communication technology or a proximity wireless communication technology. Specifically, a communication method according to a standard included in a wireless PAN (personal area network) may be applied, or a communication method according to a standard included in a wireless LAN may be applied. Standards included in the wireless LAN include IEEE802.11a, IEEE802.11b, IEEE802.11g, and IEEE802.11n. Standards included in the wireless PAN include UWB (Ultra Wide Band), ZigBee, Bluetooth, and the like. Even if the wireless LAN access point is installed in a location where the wireless LAN access point cannot be recognized by the camera, the wireless LAN access point notifies the URL of the wireless LAN access point using short-range wireless communication technology. URL can be notified. Further, the wireless LAN access point may notify the URL of the wireless LAN access point by infrared communication technology.

  In addition, the wireless LAN access point may notify the wireless communication terminal by attaching the URL of the wireless LAN access point in the wireless LAN beacon attached with the AP identifier.

<Second Embodiment>
<Wireless communication system>
The wireless communication system according to the present embodiment includes a wireless LAN access point and a wireless communication terminal, as in the first embodiment. Further, a router and a name server may be included as necessary. Similar to the first embodiment, the wireless communication terminal is a dual-mode portable terminal having a wireless WAN interface and a wireless LAN interface. The wireless communication terminal 506 functions as a wireless LAN terminal (STA) in the wireless LAN.

<Wireless LAN access point>
This wireless LAN access point differs from the wireless LAN access point according to the first embodiment in that a fixed URL is not embedded in advance. Except that the fixed URL is not embedded in advance, the wireless LAN access point according to the first embodiment described with reference to FIGS. 1 and 2 can be used.

<Wireless communication terminal>
The wireless communication terminal is the same as the wireless LAN access point according to the first embodiment.

<Operation of this wireless communication system>
The operation of this wireless communication system will be described.

  FIG. 8 shows an example of a network to which the present wireless LAN access point and the present wireless communication terminal are applied.

  In FIG. 8, a wireless LAN access point (AP1) 502, a wireless LAN access point (AP2) 504, a wireless communication terminal 506, and a router 508 are depicted. 5 differs from the network shown in FIG. 5 in that the network shown in FIG. 8 does not have the name server 512 and the communication network 510 and the communication network 514 are directly connected.

  FIG. 9 shows the operation of the wireless communication system.

  Hereinafter, a method in which the wireless communication terminal 506 performs wireless LAN setting for the wireless LAN access point 502 will be described.

  After purchasing the wireless LAN access point 502, the user connects to a home router (step S902). For example, the wired communication frame receiving unit 213 and the wired communication frame transmitting unit 220 are connected to the wired network.

  The wireless LAN access point 502 is assigned a local address from the router 508 by DHCP (step S904). The wireless LAN access point 502 is connected to a local network under the router 508. The wireless LAN access point 502 is connected to a local network under the router 508. For example, the wired communication frame transmission unit 220 is assigned a local address from the router 508 by accessing the router 508 by DHCP.

  The wireless LAN access point 502 identifies a global address as URI information assigned to the local network (step S906). For example, the wired communication frame receiving unit 213 acquires a global address from the router 508. Then, the wired communication frame receiving unit 213 inputs the global address to the global address analyzing unit 214. The global address analysis unit 214 inputs the global address to the URI management unit 216.

  The wireless LAN access point 502 broadcasts a beacon accompanied by the global address acquired in step S906, the communication port number, and the AP identifier of the wireless LAN access point 502 through the wireless LAN interface (step S908). The communication port number is a communication port number for accessing the wireless LAN access point 502 from the router 508. For example, the wireless LAN frame transmission unit 208 acquires a global address and port number by the URI management unit 216, and wirelessly transmits a beacon including the global address and port number. The wireless LAN frame is received by the wireless LAN frame reception unit 401 and input to the beacon analysis unit 402. The beacon analysis unit 402 inputs the global address and port number included in the wireless LAN frame input by the wireless LAN frame reception unit 401 to the URI management unit 407 of the connection destination AP.

  The wireless communication terminal 506 creates wireless LAN setting information to be set in the wireless LAN access point 502 (step S910). The wireless LAN setting information includes SSID, encryption communication key, frequency channel, beacon period, and the like. The encrypted communication key may be calculated using a random number. Security can be improved by calculating the encryption communication key using a random number. For example, the wireless LAN setting information creation unit 408 creates wireless LAN setting information and inputs it to the wireless LAN setting information frame creation unit 409.

  The wireless LAN access point 502 broadcasts a beacon accompanied by the AP identifier of the wireless LAN access point 502 through the wireless LAN interface (step S912). For example, the AP identifier notification frame creation unit 206 acquires the AP identifier by the AP identifier management unit 205. Then, the AP identifier notification frame creation unit 206 creates an AP identifier notification frame including the AP identifier and transmits it from the wireless LAN frame transmission unit 208. The wireless LAN access point 502 may weaken the beacon transmission power. For example, the transmission power control unit 207 controls the transmission power of the AP identifier notification frame to be weak. By reducing the transmission power, the beacon arrival area can be narrowed, so that the AP identifier can be prevented from leaking outside the home. In other words, only the user at home can recognize the AP identifier. At this time, the wireless LAN access point 502 has no setting items for each wireless LAN. Therefore, each value in the beacon to be described in IEEE802.11 such as SSID may be left unset, or an arbitrary value may be set. The wireless communication terminal 506 receives the beacon transmitted by the wireless LAN access point 502. For example, the wireless LAN frame reception unit 401 receives a beacon and inputs it to the beacon analysis unit 402. The beacon analysis unit 402 inputs the AP identifier included in the beacon to the wireless LAN setting information frame creation unit 409.

  The wireless communication terminal 506 transmits a probe request frame including the identifier (STA identifier) of the wireless communication terminal 506 via the wireless LAN interface (step S914). For example, the STA identifier notification frame creation unit 404 acquires the STA identifier by the STA identifier management unit 403. The wireless LAN setting information may be acquired as a trigger. Then, the STA identifier notification frame creation unit 404 creates a probe request frame including the STA identifier and transmits it from the wireless LAN frame transmission unit 405. The wireless LAN access point 502 receives the probe request frame transmitted by the wireless communication terminal 506 and acquires the STA identifier. For example, the probe request frame transmitted by the wireless communication terminal 506 is received by the wireless LAN frame receiving unit 201. The wireless LAN frame reception unit 201 inputs the probe request frame to the reception RSSI analysis unit 202. The received RSSI analysis unit 202 inputs a valid probe request frame to the STA identifier analysis unit 203. The STA identifier analysis unit 203 inputs the reception time of the valid probe request frame to the reception information validity confirmation unit 211 together with the STA identifier included in the valid probe request frame. When the wireless LAN access point 502 acquires the STA identifier, the wireless LAN access point 502 can be made to recognize the wireless communication terminal that issues a command regarding the setting of the wireless LAN.

  The wireless LAN access point 502 may validate only probe request frames received from the wireless communication terminal 506 that have a predetermined reception strength or higher. By enabling only probe request frames with a predetermined reception strength or higher, even if a malicious one transmits a probe request frame from outside the home, the probe request frame has low reception strength. Since the reception strength is low, the wireless LAN access point 502 does not validate the probe request frame. Therefore, it can be avoided that a malicious user impersonates an authorized user from outside the home and causes the wireless LAN access point 502 to recognize a wireless communication terminal that issues a command related to wireless LAN setting. As described above, the identifier is exchanged between the wireless LAN access point 502 and the wireless communication terminal 506.

  The processing in steps S916 to S926 is the same as the processing in steps S622 to S632 described with reference to FIG.

Then, the connection setting to the wired network at the wireless LAN access point and the setting related to the wireless LAN can be realized without manual input by the user. Since the connection setting to the wired network at the wireless LAN access point and the setting related to the wireless LAN can be realized without manual input by the user, the convenience of the user in the setting of the wireless LAN access point can be improved.

  Further, the wireless LAN access point registers the URL of the wireless LAN access point, the URL registration step executed by the URI management unit 216, and the URL registered in the name server by the URL registration step. And a registration request step executed by the URL registration request frame creation unit 219 and the wired communication frame transmission unit 220 for requesting to register the correspondence with the global address of the local network to which the wireless LAN access point belongs, A URL notification step executed by the URI information notification unit 215 for causing the wireless communication terminal to recognize the URL registered in the URL registration step.

  The wireless communication terminal acquires the URL of the wireless LAN access point, the URL acquisition step executed by the URI information receiving unit 406, and the URL acquired by the URL acquisition step by the wireless WAN interface. A global address request step executed by the global address inquiry frame creation unit 412 and the cellular transmission unit 413 of the connection destination AP. In the UI information acquisition step, the global address of the wireless LAN access point transmitted by the name server as a response to the request in the global address request step is acquired.

  According to this method, the wireless LAN access point can set a URL in advance in the wireless LAN access point, and can associate a global address with the URL. The URL can be recognized by the wireless communication terminal.

  In the UI information acquisition step, the UI information of the wireless LAN access point is acquired by reading the UI of the wireless LAN access point attached to the wireless LAN access point.

  According to this method, the wireless communication terminal can be recognized by converting the URI of the wireless LAN access point into image information such as a two-dimensional barcode. Since most wireless communication terminals in recent years are equipped with a camera, it is possible to reduce the mounting cost.

  In the UI information acquisition step, the UI information of the wireless LAN access point is acquired by performing wireless communication with the wireless LAN access point using a short-range wireless communication technology or a proximity wireless communication technology.

  According to the present method, the wireless communication terminal can recognize the URI of the wireless LAN access point by overlapping the proximity wireless communication interfaces between the wireless LAN access point and the wireless communication terminal. The operation of superimposing the close proximity wireless interfaces is very easy for the user, and since the possibility that the radio waves leak to the surroundings is extremely small, it is also effective in terms of security. The wireless communication terminal may be made to recognize the URI of the wireless LAN access point by infrared communication. The wireless communication terminal may be made to recognize the URI of the wireless LAN access point via Bluetooth.

  In the UI information notification step, the wireless LAN interface wirelessly transmits a wireless LAN frame attached with the UI information acquired in the UI information acquisition step, and in the UI information acquisition step, the UI information is acquired. By receiving the wireless LAN frame wirelessly transmitted in the eye information notification step, the UI information of the wireless LAN access point is acquired.

  According to this method, the wireless communication terminal can recognize the URI of the wireless LAN access point through the wireless LAN.

  In the wireless LAN setting information creation step, the wireless LAN access point SS ID, an encryption key for wireless LAN communication, a frequency channel used for wireless LAN communication, a beacon transmission cycle of the wireless LAN access point, the wireless LAN access One of the random backoff parameters of the wireless LAN communication terminal accommodated in the point and the wireless LAN cell is created.

  According to this method, the SSID to be set in the wireless LAN access point can be automatically generated in the wireless communication terminal. By automatically generating the SSID within the wireless communication terminal, manual input by the user becomes unnecessary, and the burden on the user can be reduced. In addition, since the encryption key used in the wireless LAN communication can be automatically generated as a random value in the wireless communication terminal, the user's manual input becomes unnecessary, and the user burden is reduced. Moreover, since the value becomes random, security can be improved.

  Generally, a wireless LAN access point scans all frequency channels in the surrounding wireless environment to determine an appropriate frequency channel, and a wireless communication terminal searches for a frequency channel set by the wireless LAN access point. The procedure is to scan all frequency channels. According to this method, since the wireless communication terminal determines in advance the frequency channel to be used in the wireless LAN access point and the wireless LAN, efficient wireless LAN connection can be achieved.

  In general, the user manually inputs the beacon period to the wireless LAN access point. However, according to this method, the beacon period is automatically determined in the wireless communication terminal, so that the burden on the user is reduced.

  In normal wireless LAN communication, random backoff parameters such as CWmin and CWmax are set by user manual input or default values. If the random back-off parameter is large, the transmission waiting time becomes long, and the priority for acquiring the transmission right decreases. Conversely, if the random backoff parameter is small, the transmission waiting time becomes long, and the priority for acquiring the transmission right increases. According to this method, since the wireless communication terminal automatically determines the random backoff parameter of the wireless LAN access point, the transmission priority of the wireless LAN access point is set higher or lower than the subordinate wireless communication terminal. Can contribute to communication quality control.

  In the UI information notification step, the beacon including a global address of a network to which the wireless LAN access point belongs and a port number communicable with the wireless LAN access point is wirelessly transmitted by the wireless LAN interface, and the UI information is acquired.

When the wireless communication terminal knows the URL of the wireless LAN access point, it can recognize the global address to be set as the transmission destination of the wireless LAN access point using cellular.

  In the wireless LAN setting information frame transmission step, the destination is the global address acquired and received by the UI information acquisition step and the port number that can communicate with the wireless LAN access point.

  According to this method, the wireless LAN access point can notify the wireless communication terminal of the global address and communication port number of the local network to which the wireless LAN access point belongs. The wireless communication terminal can transmit a frame to the wireless LAN access point using cellular.

  In the wireless communication terminal, in the legitimacy determination step, an identifier of the wireless communication terminal included in the wireless LAN setting information frame received in the wireless LAN setting information frame receiving step is obtained by the wireless communication terminal identifier acquiring step.
