Description

  The present invention relates to a wireless communication method and a wireless communication system for performing communication using HTTP between mobile stations.

  In recent years, mobile stations having a wireless communication function such as PHS (Personal Handy phone System) and mobile phones have become widespread, and the communication speed and communication quality have been increased along with the reduction in size and weight. Further, along with the advancement of such hardware functions, in addition to simple call functions, it has become possible to perform mail transmission / reception functions, imaging functions, music playback functions, Web browsing functions, and TV viewing functions. Among them, the Web browsing function can be said to be a function that is very suitable for a mobile station in that it can easily cope with user needs in real time.

  In general, Web browsing refers to acquiring Web content (bulletin board, blog, etc.) using a Web browser from a Web server connected to a communication network according to HTTP (Hyper Text Transport Protocol). However, since such a Web server is costly to install and manage, the user uses his / her disk space provided by an Internet service provider (ISP: Internet Service Provider) to display his / her home page. It has been established. In any case, when such information transmission is performed, the creation and update of the Web content established in the Web server must be performed by directly accessing the Web server, which involves complicated processing.

Therefore, a technique for mounting a Web server function on the mobile station itself is being studied. For example, Patent Literature 1 describes a mobile station (mobile device) having a function of a content server, and discloses that content is changed in real time. In addition, a mobile device authentication apparatus is installed in the wired area of the mobile communication system network to authorize the use of the mobile device.
Japanese Patent Laid-Open No. 2002-244958

  Nowadays, each individual owns a telephone that has been one unit in the family, and various functions such as Web browsing can be enjoyed individually. In addition to sharing information through public web content that anyone can view, there is a growing need for information sharing in a closed communication environment only between small groups sharing the purpose and behavior. . In such a small group, a system that publishes information specific to the group on a Web page that can be browsed only within the group is desired.

  However, as described above, the Web server through the ISP involves complicated processing in content creation and update. Moreover, since it is not assumed that such a Web server restricts users, it is troublesome to restrict access to only a small group. Furthermore, although the authentication apparatus is provided in the technology for mounting the above-described Web server function in the mobile station itself, the arrangement is limited to the wired area and the ISP is forced to be used, so a small group that is difficult to manage strictly. I was not familiar with the technology.

  In view of such problems, the present invention consolidates the operation of the Web server to the mobile station side, guarantees the ease of content update and reduces the operation cost, and is excellent in tamper resistance and secure information within a small group. An object of the present invention is to provide a wireless communication method and a wireless communication system that can be disclosed.

  In order to solve the above problems, a typical configuration of the present invention is that a plurality of mobile stations including a Web mobile station that functions as a Web server and an authentication mobile station that authenticates other mobile stations are wirelessly connected to a base station. A wireless communication method for performing communication using HTTP through communication, wherein an arbitrary mobile station makes a connection request to the Web server of the Web mobile station, and the Web mobile station makes an arbitrary mobile station in response to the connection request A connection response is made, and an arbitrary mobile station requests authentication from the authentication mobile station. The authentication mobile station authenticates an arbitrary mobile station based on an access key of the arbitrary mobile station, and the arbitrary mobile station is authenticated. Then, the Web mobile station requests authentication from the authentication mobile station, and the authentication mobile station authenticates the Web mobile station based on the access key of the Web mobile station. Stations and web mobile stations It is characterized by establishing a communication connection using HTTP.

  With a configuration in which a web server is mounted on a mobile station, it is possible to directly and easily create and update (add, delete) web content for the mobile station of the mobile station. Management makes it possible to operate at low cost without relying on ISP. In addition, since access key and destination information of the authentication mobile station are valid only within the group, it is excellent in tamper resistance, and it is possible to safely disclose information within a small group by preventing unauthorized access from outside and Web server impersonation. To do. Such Web server manageability, low operation cost, and tamper resistance function optimally for a closed community of small group members.

  In the above authentication, the authentication mobile station transmits a calculation value and a calculation method to an arbitrary mobile station or Web mobile station, and the arbitrary mobile station or Web mobile station uses its own access key and calculation value. The calculation may be performed by calculating using a calculation method, transmitting the calculation result to the authentication mobile station, and the authentication mobile station determining whether the calculation result is correct or not.

  With this configuration, the authentication mobile station can arbitrarily select a calculation value and a calculation method each time, and dynamic authentication can be performed. Therefore, even if a past calculation result leaks to a third party, it is not authenticated when an attempt is made to use the calculation result, and unauthorized access from the outside and Web server impersonation can be reliably prevented.

  When a plurality of authentication mobile stations are set, each of the plurality of mobile stations has an authentication order list describing the authentication order of the plurality of authentication mobile stations, and any mobile station or Web mobile station is based on an access key. Until authentication is performed, authentication may be sequentially requested from the authentication mobile station according to the authentication order list.

  With this configuration, it is possible to avoid a situation in which authentication is not performed due to power-off of the authentication mobile station or movement outside the service area, and smooth connection to a desired Web server is possible. Also, by distributing the authentication order list only within a predetermined group, unauthorized access from outside and impersonation of the Web server can be more strictly prevented, and safe information disclosure within a small group becomes possible.

  If any mobile station or Web mobile station cannot communicate with all the authentication mobile stations listed in the authentication order list via the base station, the authentication mobile station uses short-range wireless communication not via the base station. May require authentication. In addition, when a mobile connection with a Web mobile station via a base station is impossible, an arbitrary mobile station may attempt communication connection with the Web mobile station using short-range wireless communication not via the base station.

  With this configuration, it is possible to avoid the problem that authentication and Web content cannot be used even when the target authentication mobile station or Web mobile station is located at a short distance, and the communication connection with the Web server is more reliably established. It becomes possible to carry out.

  Another configuration of the present invention includes a mobile station including a Web mobile station that functions as a Web server and an authentication mobile station that authenticates other mobile stations, and a base station, and the mobile station through wireless communication with the base station A wireless communication system capable of communicating with each other using an HTTP, wherein an arbitrary mobile station includes a connection request unit that makes a connection request to the Web server of the Web mobile station, and an authentication mobile station based on an access key that the mobile station has An arbitrary authentication request unit that requests authentication from the authentication mobile station, and an arbitrary communication establishment unit that establishes a communication connection using the HTTP with the Web mobile station after the Web mobile station is authenticated after receiving authentication from the authentication mobile station; The Web mobile station requests authentication from the authentication mobile station based on the connection response unit that makes a connection response to the arbitrary mobile station in response to a connection request from the arbitrary mobile station and the access key that the Web mobile station has. We An authentication requesting unit and a Web communication establishing unit that establishes a communication connection using HTTP with an arbitrary mobile station after obtaining authentication from the authentication mobile station, and the authentication mobile station has access to any mobile station An arbitrary authentication unit that authenticates an arbitrary mobile station based on the key, and a Web authentication unit that authenticates the Web mobile station based on an access key included in the Web mobile station.

  With such a wireless communication system, as in the wireless communication method described above, it is possible to disclose information safely within a small group with excellent tamper resistance while ensuring ease of content update and reduction in operation costs.

  The component corresponding to the technical idea in the wireless communication method mentioned above and its description are applicable also to the said wireless communication system.

  As described above, according to the present invention, the operation of the Web server is concentrated on the mobile station side to ensure the ease of content update and the reduction of operation cost, and it is excellent in tamper resistance and safe information within a small group. Open to the public.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated.

(Wireless communication system 100)
In this embodiment, each individual mobile station is positioned as a mobile station belonging to a predetermined group, and communication within the closed communication environment by the predetermined group is realized. In particular, between mobile stations through wireless communication with a base station Communication using HTTP becomes possible. Here, for easy understanding, the configuration of the entire wireless communication system will be described, and then individual components will be described in detail.

The wireless communication system 100 includes a plurality of mobile stations 110 (110A, 110B, 110C), a plurality of base stations 120 (120A, 120B, 120C), an ISDN (Integrated Services Digital Network) line, the Internet, a dedicated line, and the like. And a communication network 130 to be configured.

(Mobile station 110)
In the present embodiment, a PHS terminal is cited as the mobile station 110. However, the mobile station 110 is not limited to a PHS terminal, but is a mobile phone, a notebook personal computer, a PDA (Personal Digital Assistant), a digital camera, a music player, a car navigation system, a portable TV, a game device, a DVD player, a remote controller, etc. Various electronic devices that are communicable and can operate independently by a battery or the like can also be used as a mobile station.

  In the present embodiment, among the mobile stations 110A, 110B, and 110C in FIG. 1, the mobile station 110B functions as a Web server, and the mobile station 110C has a function of authenticating other mobile stations 110. The mobile stations 110A, 110B, and 110C can be configured with the same hardware, but when the mobile station 110B is used as a Web server, the Web mobile station 110B and when the mobile station 110C is used as a mobile station having an authentication function are authenticated mobile stations Call 110C. In the present embodiment, for example, an arbitrary mobile station 110A obtains authentication of the authentication mobile station 110C via the base station 120A, the communication network 130, and the base station 120C, and further passes through the base station 120A, the communication network 130, and the base station 120B. Web content of the Web mobile station 110B is acquired.

  2 is a functional block diagram showing a hardware configuration of the mobile station 110, and FIG. 3 is a perspective view showing an external appearance of the mobile station 110. As shown in FIG. The mobile station 110 includes a mobile station control unit 160, a mobile station memory 162, a display unit 164, an operation unit 166, a voice input unit 168, a voice output unit 170, and a mobile station radio communication unit 172. Composed.

  The mobile station control unit 160 manages and controls the entire mobile station 110 by a semiconductor integrated circuit including a central processing unit (CPU). In addition, the mobile station control unit 160 performs a call function, a mail transmission / reception function, an imaging function, a music playback function, a Web browsing function, and a TV viewing function using the program in the mobile station memory 162.

  The mobile station memory 162 is composed of ROM, RAM, EEPROM, nonvolatile RAM, flash memory, HDD (Hard Disk Drive), etc., and stores programs processed by the mobile station control unit 160, audio data, and the like. In the present embodiment, an access key distributed only within a predetermined group and an authentication order list are also stored.

  The display unit 164 is configured with a liquid crystal display, EL (Electro Luminescence), etc., stored in the mobile station memory 162, or provided from an application relay server (not shown) via the communication network 130, An application GUI (Graphical User Interface) can be displayed.

  The operation unit 166 includes switches such as a keyboard, a cross key, and a joystick, and accepts a user operation input. When the mobile station 110 functions as a Web server, the Web content can be created and updated directly through the operation unit 166.

  The voice input unit 168 includes voice recognition means such as a microphone, and converts a user voice input during a call into an electric signal that can be processed in the mobile station 110.

  The voice output unit 170 is configured by a speaker, and converts the voice signal of the communication partner received by the mobile station 110 into voice and outputs the voice. In addition, a ring tone, an operation sound of the operation unit 166, an alarm sound, and the like can be output.

  The mobile station radio communication unit 172 performs radio communication with the base station 120 in the communication network 130. As such wireless communication, a time division multiplexing (TDM) method in which a plurality of time slots obtained by time-dividing frames in the base station 120 are respectively assigned to channels of the mobile station 110 to perform communication is adopted. ing.

  Further, the mobile station control unit 160 of this embodiment also functions as a connection request unit 180, an arbitrary authentication request unit 182 and an arbitrary communication establishment unit 184.

  The connection request unit 180 makes a connection request to a Web server managed separately from the telephone number and e-mail of the mobile station 110 in a mobile station (Web mobile station) having a Web server function. Specifically, the connection request unit 180 designates a desired URL (Uniform Resource Locator) from a Web browser provided in its own mobile station 110, and indexes the Web server of the Web mobile station 110B specified by the URL. Requests a file (index.html etc.). In response to such a request, the Web mobile station 110B transmits an index file and then sequentially transmits necessary files. However, in this embodiment, since authentication is required to start such communication connection, the Web mobile station 110B returns only a connection response and transmits an index file after receiving authentication of the authentication mobile station 110C as will be described later. Will be.

  The arbitrary authentication request unit 182 requests authentication from the authentication mobile station 110C based on the access key that the arbitrary authentication request unit 182 has. Specifically, the arbitrary authentication request unit 182 makes an authentication request to the authentication mobile station 110C, and refers to the calculation value and the calculation method received from the authentication mobile station 110C in response thereto, and the access key and the calculation value that the self authentication request unit 182 has Are calculated by the calculation method, and the calculation result is transmitted to the authentication mobile station 110C. If the calculation result is correct, a permit can be obtained from the authentication mobile station 110C. Such calculation values, calculation methods, calculation results, and permits can be encrypted with a common encryption key within the group.

  At this time, the arbitrary authentication request unit 182 selects the authentication mobile station 110C as an authentication destination by referring to the authentication order list that is commonly used in the group.

  In the wireless communication system 100, since a plurality of authentication mobile stations can be set, any mobile station 110 in the group can be registered as an authentication mobile station. In the authentication order list described above, the priority order of authentication is determined, and the arbitrary authentication request unit 182 sequentially tries authentication to the authentication mobile station according to the authentication order list until authentication based on the access key is performed. .

  With this configuration, it is possible to avoid a situation in which authentication is not performed due to power-off of the authentication mobile station 110C or movement outside the service area, and a smooth connection to a desired Web server is possible. Also, by distributing the authentication order list only within a predetermined group, unauthorized access from outside and impersonation of the Web server can be more strictly prevented, and safe information disclosure within a small group becomes possible.

  Further, like the authentication order list, the access key is distributed only to the mobile stations 110 belonging to the predetermined group. With this configuration, the communication environment of the group can be isolated from the outside, and unauthorized access can be more strictly prevented.

  The arbitrary communication establishment unit 184 obtains authentication from the authentication mobile station 110C (acquires a permit), and then waits for the web mobile station 110B to be authenticated and establishes a communication connection using the HTTP with the web mobile station 110B. To do.

  When the mobile station 110 operates as the Web mobile station 110B, the mobile station control unit 160 further functions as an IP address acquisition unit 186, a connection response unit 188, a Web authentication request unit 190, and a Web communication establishment unit 192.

  The IP address acquisition unit 186 acquires the IP address of its own Web server at the same time as its own location registration with respect to the wireless communication system 100 after the mobile station 110 is activated. Such an IP address may be a fixed IP address or a dynamic IP address.

  When there is a connection request from another mobile station 110 to its own Web server, the connection response unit 188 first returns a connection response to the mobile station 110 that has made the connection request only to the effect that the connection request has been accepted. To do.

  The Web authentication request unit 190 requests authentication from the authentication mobile station 110C based on the access key that it has. Specifically, the Web authentication request unit 190 makes an authentication request to the authentication mobile station 110C, and refers to the calculation value and calculation method received from the authentication mobile station 110C accordingly, and the access key and calculation value that the web authentication request unit 190 has. Are calculated by the calculation method, and the calculation result is transmitted to the authentication mobile station 110C. If the calculation result is correct, a permit can be obtained from the authentication mobile station 110C.

  The Web communication establishment unit 192 establishes a communication connection using HTTP with another mobile station 110 after obtaining authentication (acquiring a permit) from the authentication mobile station 110C.

  Furthermore, when the mobile station 110 operates as the authentication mobile station 110C, the mobile station control unit 160 further functions as an arbitrary authentication unit 194 and a Web authentication unit 196.

  The arbitrary authentication unit 194 authenticates the other mobile station 110 based on the access key that the other mobile station 110 has. Specifically, the arbitrary authentication unit 194 arbitrarily or randomly selects a calculation value and a calculation method in response to an authentication request from another mobile station 110, transmits the calculation value to another mobile station 110, and further moves other mobile stations 110 When the correctness of the calculation result returned from the station 110 is determined and it is determined to be correct, a permit is transmitted to another mobile station 110. Here, the operation numerical value is any integer that can be used for the operation, and it does not matter what number it is. Arithmetic methods include various integer calculation methods such as addition, subtraction, multiplication, division and logical operations (logical product, logical sum, exclusive logical sum), and transmission of the calculation method can identify the calculation method This is done by sending a unique identifier. Further, such calculation values and calculation methods are valid until the communication connection is completed after the communication connection by the arbitrary communication establishment unit 184 and the Web communication establishment unit 192 is established.

  The Web authentication unit 196 authenticates the Web mobile station 110B based on the access key of the Web mobile station 110B by the same operation as the arbitrary authentication unit 194.

  With the configuration of the arbitrary authentication unit 194 and the Web authentication unit 196, the authentication mobile station 110C can arbitrarily select a calculation value and a calculation method each time, and dynamic authentication is possible. Therefore, even if a past calculation result leaks to a third party, it is not authenticated when an attempt is made to use the calculation result, and unauthorized access from the outside and Web server impersonation can be reliably prevented.

  Further, the authentication by the arbitrary authentication unit 194 or the Web authentication unit 196 may confirm not only the comparison of access keys but also the telephone number of the mobile station that is the transmission source. With this configuration, when a telephone number is registered in the target group, access from other unauthorized users can be more reliably prevented.

  When the mobile station 110 described above functions as the Web mobile station 110B and the authentication mobile station 110C in a predetermined group, Web content can be exchanged in a closed communication environment.

(base station)
FIG. 4 is a block diagram illustrating a schematic configuration of the base station 120. The base station 120 includes a base station control unit 210, a base station memory 212, a base station wireless communication unit 214, and a base station wired communication unit 216.

  The base station control unit 210 manages and controls the entire base station 120 by a semiconductor integrated circuit including a central processing unit (CPU). In addition, the base station control unit 210 controls communication connection of the mobile station 110 to the communication network 130 and other mobile stations 110 using a program in the base station memory 212.

  The base station memory 212 includes ROM, RAM, EEPROM, nonvolatile RAM, flash memory, HDD, and the like, and stores programs processed by the base station control unit 210, time information, and the like.

  The base station radio communication unit 214 can establish communication with the mobile station 110 and adaptively change the modulation scheme and codec according to the communication quality of the mobile station 110.

  The base station wired communication unit 216 can be connected to various servers including an application relay server via the communication network 130.

  In the wireless communication system 100 described above, a web server is mounted on the mobile station 110, so that web content can be created and updated (added or deleted) directly and easily to the mobile station 110 itself. In addition, by managing the Web server in its own mobile station 110, it is possible to operate at low cost without relying on ISP. In addition, since access key and authentication mobile station destination information is valid only within the group, it is highly tamper-resistant, allowing unauthorized access from the outside and Web server impersonation, enabling safe information disclosure within a small group. To do. Such Web server manageability, low operation cost, and tamper resistance function optimally for a closed community of small group members. A wireless communication method in which the mobile station 110 performs communication using HTTP through wireless communication with the base station 120 using the wireless communication system 100 will be described in detail below.

(Wireless communication method)
FIG. 5 is a sequence diagram illustrating a processing flow of the wireless communication method. Here, an operation in which an arbitrary mobile station 110A obtains the authentication of the authentication mobile station 110C and acquires the Web content of the Web mobile station 110B is shown. Here, an access key, for example, “1234A (hexadecimal number)” is distributed to all mobile stations 110 in advance.

  The mobile station 110A launches a web browser in its own mobile station 110A (S300), designates a desired web server of the web mobile station 110B in the group by a specific URL, and makes a connection request (S302). The Web mobile station 110B returns a response indicating that the connection request has been received to the mobile station 110A as a connection response (S304).

  110 A of mobile stations grasp | ascertain that it is possible to refer the web content of the web mobile station 110B by the connection response of the web mobile station 110B, and start the authentication operation | movement for acquiring the web content.

  The mobile station 110A refers to the authentication order list, selects the authentication mobile station 110C to be authenticated, and then makes an authentication request to the authentication mobile station 110C (S306). In response to the authentication request, the authentication mobile station 110C selects a calculation value and a calculation method, for example, a calculation value “1 (hexadecimal number)” and a calculation method “addition”, and transmits them to the mobile station 110A (S308). When the mobile station 110A receives the operation value and the operation method, the mobile station 110A “adds” the operation value “1” to the access key of itself, for example, “1234A (hexadecimal number)” according to the operation method (S310). A certain “1234B (hexadecimal number)” is transmitted to the authentication mobile station 110C (S312). The authentication mobile station 110C determines whether or not the calculation result “1234B (hexadecimal)” matches the assumed calculation result (S314). If they match, the authentication mobile station 110C sends a communication permit to the mobile station 110A. Issue (S316). The mobile station 110A notifies the Web mobile station 110B that it has acquired a permit, and prompts authentication of the Web mobile station 110B (S318).

  Subsequently, similarly to the mobile station 110A, the Web mobile station 110B selects the authentication mobile station 110C to be authenticated with reference to the authentication order list, and then makes an authentication request to the authentication mobile station 110C (S320). In response to the authentication request, the authentication mobile station 110C selects a calculation value and a calculation method, for example, a calculation value “2 (hexadecimal number)” and a calculation method “multiplication”, and transmits them to the Web mobile station 110B (S322). . Upon receiving the operation value and the operation method, the Web mobile station 110B “multiplies” the operation value “2” to its own access key, for example, “1234A (hexadecimal number)” according to the operation method (S324), and the operation result "2474 (hexadecimal number)" is transmitted to the authentication mobile station 110C (S326). The authentication mobile station 110C determines whether or not the calculation result “2474 (hexadecimal)” matches the assumed calculation result (S328). If they match, the authentication mobile station 110C gives a communication permit to the Web mobile station 110B. (S330). At this time, the authentication mobile station 110C ends the authentication process and is released from the communication connection between the mobile station 110A and the Web mobile station 110B. When the Web mobile station 110B itself obtains a permit, it establishes a communication connection using HTTP with the mobile station 110A (S332).

  Here, the mobile stations 110A, 110B, and 110C have different functions, but all the mobile stations 110 can function as normal mobile stations 110A, Web mobile stations 110B, and authentication mobile stations 110C. It is also possible to perform a plurality of functions simultaneously. Further, when one mobile station 110 performs two or more functions simultaneously, authentication between the same mobile stations can be omitted.

  When an arbitrary user enters the predetermined group described above, an access key and an authentication order list are acquired from the manager of the group. Then, Web browsing and Web publication become possible. However, regarding the authentication function, it is desirable to distribute the calculation value and calculation method selection program only to more reliable users. In this way, unauthorized access can be prevented more strictly.

  FIG. 6 is a sequence diagram showing another processing flow of the wireless communication method. Here, the operation in which the mobile station 110A obtains the authentication of the authentication mobile station 110C and acquires the Web content of the Web mobile station 110B is shown. However, it is assumed that the authentication mobile station 110C is out of service area and cannot communicate.

  The mobile station 110A starts up a Web browser in its own mobile station 110 (S300), and makes a connection request to the Web mobile station 110B (S302). The Web mobile station 110B returns a response indicating that the connection request has been received to the mobile station 110A as a connection response (S304).

  The mobile station 110A starts an authentication operation upon receiving a connection response from the Web mobile station 110B. The mobile station 110A refers to the authentication order list, selects the authentication mobile station 110C to be authenticated, and then makes an authentication request to the authentication mobile station 110C (S306). Here, when the mobile station 110A recognizes that the authentication mobile station 110C cannot communicate and is not authenticated, the mobile station 110A becomes the authentication mobile station 110D having the second highest priority in the authentication order list. An authentication request is made (S350). In response to the authentication request, the authentication mobile station 110D transmits a calculation value and a calculation method to the mobile station 110A (S308). Since the subsequent processing is the same as the processing described with reference to FIG. 5 except for the different authentication mobile stations, detailed description thereof is omitted here. Thus, communication connection with the Web server 110B can be more reliably performed regardless of the communication status of the specific authentication mobile station 110C.

  On the other hand, when communication connection with all authentication mobile stations or Web mobile stations listed in the authentication order list is impossible, the mobile station 110 may attempt communication connection using short-range wireless communication not via the base station 120. it can.

  FIG. 7 is a sequence diagram illustrating another processing flow of the wireless communication method. Here, the mobile station 110A attempts to acquire the Web content of the Web mobile station 110B.

  The mobile station 110A starts up a Web browser in its own mobile station 110 (S300), and makes a connection request to the Web mobile station 110B (S302). At this time, if the mobile station 110A or the Web mobile station 110B cannot communicate with the base station 120, the connection request does not reach the Web mobile station 110B.

  However, for example, when the mobile station 110A and the Web mobile station 110B are at a distance where short-range wireless communication is possible, it is unreasonable that a communication connection cannot be made. Therefore, the mobile station 110A in the present embodiment can establish communication with the Web mobile station 110B by short-range wireless communication (S400). The same applies to the authentication mobile station 110C. Here, for short-range wireless communication, various existing methods such as Bluetooth, wireless LAN, infrared communication, ZigBee, APAN (Wireless Personal Area Network), and NFC (Near Field Communication) can be adopted.

  With this configuration, it is possible to avoid the problem that authentication and Web content cannot be used even when the target authentication mobile station or Web mobile station is located at a short distance, and the communication connection with the Web server is more reliably established. It becomes possible to carry out. Further, near field communication is limited in communication distance, and communication can be performed while confirming a communication partner. Therefore, even if mobile stations acquire Web contents without authentication, it is valid. It is possible to confirm access.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment.
