JP 2003-324446 A

  Various communication settings are required for an information device (hereinafter referred to as an “information communication terminal”) having these communication functions to connect to a wireless local area network (LAN) defined by IEEE 802.11 or the like. It is. For example, in connection with a wireless LAN, it is used for authentication in ESSID (Extended Service Set Identifier), WEP (Wired Equivalent Privacy) key, IEEE 802.11i / WPA (Wi-Fi Protected Access), and IEEE 802.1x. Various information related to wireless LAN security such as an electronic certificate or PSK (Pre shared key) needs to be set in the information communication terminal. Further, the communication setting information for connecting to the wireless LAN is not constant, and it is necessary to change the setting as appropriate in accordance with the operation change of the system.

  Thus, the complexity of the setting input required for connecting the information communication terminal to a predetermined communication network reduces the convenience of the communication system. In addition, when the home appliance has a network connection function, it may be difficult to provide an input interface for the setting.

  The present invention has been made in view of such problems, and a main object thereof is to provide a technique for performing settings necessary for an information communication terminal to connect to a communication network with a simple interface. It is.

  In order to solve the above problem, a communication terminal device according to an aspect of the present invention stores a terminal ID, which is information required to identify the terminal device in a predetermined local area communication network, The terminal ID is transmitted by short-range wireless communication to the connection support apparatus that supports the connection of the local communication network. This device receives communication setting information necessary for the terminal device to connect to the local communication network from the connection management server that has received the terminal ID via the connection support device by short-range wireless communication via the connection support device. Receive and connect to the local communication network based on the communication setting information.

  According to this aspect, the communication terminal device transmits / receives data to / from the connection management server via short-range wireless communication with the connection support device. The short-range wireless communication may be communication using an electromagnetic wave or light within a predetermined range as a carrier wave, such as an RFID (Radio Frequency-Identification) card, Bluetooth (registered trademark), or IrDA (Infrared Data Association). . Note that the communication terminal device may be connected to the connection support device through a peer-to-peer wired connection, or may be connected to the direct connection management server. The communication terminal device can acquire communication setting information for the intended local area communication network as a connection destination through such a simple communication interface. Therefore, significant labor savings can be achieved in setting communication setting information in the communication terminal device.

  Another aspect of the present invention is a connection management server. The connection management server communicates a terminal ID, which is information required to identify a communication terminal device in a predetermined local communication network, via a connection support device that supports connection between the communication terminal device and the local communication network. The communication setting information received from the terminal device and necessary for the communication terminal device to connect to the local communication network is generated and transmitted to the communication terminal device via the connection support device.

  According to this aspect, the connection management server generates communication setting information necessary for the communication terminal device to connect to the communication network. The communication setting information is transmitted to the communication terminal device by short-range wireless communication via the connection support device. For this reason, the user of the communication terminal apparatus can save the trouble of setting the communication setting information by itself, thereby improving the convenience of the communication system.

  According to the present invention, there is an effect in simplifying the setting for the information communication terminal to connect to the communication network.

  FIG. 1 is a hardware configuration diagram of a communication system 300 in the present embodiment. The LAN 106 is installed indoors such as a general home. The LAN 106 is connected to the Internet 102 via the gateway 104. In the figure, a solid line represents a wired connection. A broken line represents a wireless connection.

  Connected to the LAN 106 are an access point 112a and an access point 112b (hereinafter simply referred to as “access point 112” when collectively referred to). Each access point 112 manages a predetermined area. For example, the area 140a managed by the access point 112a covers a living room. The area 140b managed by the access point 112b covers the study. The television 114 and the hard disk recorder 116 in the area 140a are connected to the LAN 106 via the access point 112a. Similarly, the personal computer 118 in the area 140b is connected to the LAN 106 via the access point 112b. The LAN 106 is connected to the Internet 102 via the gateway 104. The access point 112 may have a router function, or a router may be installed between the access point 112 and the LAN 106.

  A non-contact IC memory reader / writer 110 is connected to the LAN 106. The non-contact IC memory reader / writer 110 wirelessly communicates with the information communication terminal 100 and the RFID card 108 using the RFID protocol. The connection management server 200 connected to the LAN 106 performs control for the information communication terminal 100 to connect to the LAN 106. The connection management server 200 and the non-contact IC memory reader / writer 110 may be connected via a cable such as a USB (Universal Serial Bus) without using the LAN 106, or may be wirelessly communicated in an ad hoc mode.

  The information communication terminal 100 may be any device having a network connection function such as a digital camera or a mobile phone. That is, the television 114, the hard disk recorder 116, and the personal computer 118 are also a kind of the information communication terminal 100. The RFID card 108 stores a user ID that is information for uniquely identifying a user. The user ID may be set exclusively for the communication system 300. Alternatively, the user ID may be general-purpose information such as a license number. That is, the RFID card 108 may be a dedicated card corresponding to the communication system 300, but may be a general-purpose card such as a driver's license or a resident card with a built-in non-contact IC chip.

  When the user holds the RFID card 108 and the information communication terminal 100 over the contactless IC memory reader / writer 110, the contactless IC memory reader / writer 110 reads the user ID and the terminal information from each. The terminal information here refers to information such as the MAC (Media Access Control) address of the information communication terminal 100, the type of the information communication terminal 100, and the serial number unique to the non-contact IC memory. The user ID and terminal information read by the non-contact IC memory reader / writer 110 are transmitted to the connection management server 200. In the terminal information, information that uniquely identifies the information communication terminal 100 such as a MAC address is hereinafter referred to as a “terminal ID”. The terminal ID may be set exclusively for the communication system 300.

  The connection management server 200 stores user IDs of a plurality of users as registered users. The connection management server 200 determines whether the user ID received by the non-contact IC memory reader / writer 110 is registered as the user ID of the registered user. If it is not a registered user, connection is not permitted. By such a method, access by the unauthorized user to the LAN 106 is prevented. For example, even if the information communication terminal 100 is stolen, if there is no RFID card 108 on which the registered user ID is recorded, the information communication terminal 100 is refused connection to the LAN 106 by the connection management server 200.

  When permitting the connection between the information communication terminal 100 and the LAN 106, the connection management server 200 sends the communication setting information necessary for the information communication terminal 100 to connect to the LAN 106 via the non-contact IC memory reader / writer 110. To the information communication terminal 100. The communication setting information referred to here is an ESSID, WEPKEY, IEEE 802.11i / WPA (Wi-Fi Protected Access) or IEEE 802.1x used for authentication or PSK (Pre shared key), access point 112 MAC address or communication channel. The information communication terminal 100 records the communication setting information transmitted from the non-contact IC memory reader / writer 110 in the built-in memory. When the information communication terminal 100 enters each area such as the area 140a or the area 140b, the information communication terminal 100 connects to each access point 112 based on the recorded communication setting information. Hereinafter, an operation for the user to hold the information communication terminal 100 and the RFID card 108 over the contactless IC memory reader / writer 110 and connect the information communication terminal 100 to the LAN 106 is referred to as a “registration request operation”.

  According to this aspect, the user of the information communication terminal 100 performs communication settings necessary for connecting to the LAN 106 only by holding the information communication terminal 100 and the RFID card 108 over the contactless IC memory reader / writer 110. The information communication terminal 100 may read the user ID from the recording medium on which the user ID is recorded, and transmit the user ID together with the terminal information to the non-contact IC memory reader / writer 110. In this case, it is not essential for the recording medium to incorporate a non-contact IC chip.

  When the information communication terminal 100 is a device that is not portable, such as a large-sized television, or is not portable, the information communication terminal 100 itself is actually held over the non-contact IC memory reader / writer 110. Not right. In this case, a function necessary for connecting to the LAN 106 in the large TV may be provided separately as a terminal RFID card. In this case, the user holds the terminal RFID card and the user ID RFID card 108 over the contactless IC memory reader / writer 110 to store the communication setting information in the terminal RFID card. This apparatus reads the communication setting information from the terminal RFID card into a non-contact IC reader / writer built in or externally attached to the apparatus. As a result, the apparatus is connected to the access point 112. Alternatively, the non-contact IC memory reader / writer 110 itself may be configured to be portable. In that case, the user acquires the communication setting information by holding the non-contact IC memory reader / writer 110 over the large TV and the RFID card 108.

  FIG. 2 is a functional block diagram of the information communication terminal 100. Each block shown here can be realized in hardware by an element such as a CPU of a computer or a mechanical device, and in software it is realized by a computer program or the like.

  The information communication terminal 100 includes a communication unit 120, a user ID acquisition unit 122, a communication setting information storage unit 124, and a terminal information storage unit 126. The communication unit 120 performs communication processing with the outside. The communication setting information storage unit 124 stores communication setting information. The terminal information storage unit 126 stores terminal information. The terminal information storage unit 126 may be, for example, a ROM (Read Only Memory). The user ID acquisition unit 122 acquires a user ID from the RFID card 108 as necessary.

  The communication unit 120 includes an opposing wireless communication unit 128 and an access point communication unit 130. The opposing wireless communication unit 128 transmits / receives data to / from the non-contact IC memory reader / writer 110 by wireless communication. When the information communication terminal 100 is held over the contactless IC memory reader / writer 110, the opposite wireless communication unit 128 transmits the terminal information stored in the terminal information storage unit 126 to the contactless IC memory reader / writer 110. As described with reference to FIG. 1, the user ID is transmitted from the RFID card 108 to the contactless IC memory reader / writer 110. Alternatively, the user ID acquisition unit 122 may acquire the user ID, and the opposite wireless communication unit 128 may transmit the user ID together with the terminal information.

  The opposing wireless communication unit 128 receives communication setting information from the connection management server 200 via the contactless IC memory reader / writer 110 and stores the communication setting information in the communication setting information storage unit 124. Access point communication unit 130 transmits and receives data to and from access point 112 by wireless communication. Access point communication unit 130 further includes a connection processing unit 132. The connection processing unit 132 executes connection processing with each access point 112 based on the communication setting information stored in the communication setting information storage unit 124.

  FIG. 3 is a functional block diagram of the connection management server 200. Each block shown here can also be realized in terms of hardware by elements and mechanical devices such as a CPU of a computer, and in terms of software, it can be realized by a computer program or the like. Draw functional blocks. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

  The connection management server 200 includes a reader / writer interface processing unit 202, a connection management unit 204, a setting input unit 206, a registered user storage unit 208, and a connection setting information storage unit 210. The reader / writer interface processing unit 202 is in charge of interface processing with the non-contact IC memory reader / writer 110. The connection management unit 204 comprehensively manages the connection of the information communication terminal 100 with the LAN 106. The registered user storage unit 208 stores the user ID of the registered user. The connection setting information storage unit 210 stores connection setting information. The data structure of the connection setting information storage unit 210 will be described later with reference to FIG. The setting input unit 206 receives a setting input from an authorized user for connection setting information. This input may be made via an input device such as a keyboard or a mouse of the connection management server 200 or may be made from the outside via the LAN 106. The input data is stored in the registered user storage unit 208 and the connection setting information storage unit 210, respectively. Further, instead of an input from the user, the connection management server 200 may automatically generate a random number.

  The reader / writer interface processing unit 202 includes a terminal information acquisition unit 220, a user ID acquisition unit 222, and a communication setting information transmission unit 224. The terminal information acquisition unit 220 acquires terminal information from the information communication terminal 100. The user ID acquisition unit 222 acquires a user ID from the RFID card 108. The communication setting information transmission unit 224 transmits the communication setting information generated by the communication setting information generation unit 216 to the information communication terminal 100.

  The connection management unit 204 includes a connection availability determination unit 212, a mail transmission / reception unit 214, a communication setting information generation unit 216, and a terminal registration unit 218. The connection permission / non-permission determining unit 212 determines whether or not a connection request operation is possible. In the case of a connection request operation by a user who is not a registered user, the connection availability determination unit 212 does not permit connection between the information communication terminal 100 and the LAN 106.

  The mail transmission / reception unit 214 transmits / receives an e-mail to / from an administrator in order to release restrictions when the user operates each information communication terminal 100 to transmit / receive data. In this embodiment, even a registered user cannot operate devices (TV 114, hard disk recorder 116, personal computer 118) in all areas managed by the access point 112 via a network, and has a predetermined restriction. May receive. Hereinafter, when the information communication terminal 100 is used to refer to the operation of devices (the television 114, the hard disk recorder 116, and the personal computer 118) in all areas managed by the access point 112 via the LAN 106, the operation through the network is referred to as “operation via the network”. Call it. For example, the TV 114 and the hard disk recorder 116 in the living room can be operated via a network by any registered user, but the personal computer 118 in the study may be operated by only some registered users via the network. When a user who does not have the authority to operate the personal computer 118 in the study via the network attempts to perform the operation via the network, the mail transmitting / receiving unit 214 automatically transmits an email requesting permission to the user designated as the administrator. To do. When an e-mail indicating permission is received from the administrator, the user can connect the information communication terminal 100 to the network, and can operate the personal computer 118 in the study via the network. More details will be described later in connection with FIG. The communication setting information generation unit 216 generates communication setting information to be transmitted when connection is permitted for the connection request operation. The terminal registration unit 218 provides terminal information of each information communication terminal 100 to necessary devices among the access points 112, the gateway 104, and arbitrary devices managed by the access point 112 (hard disk recorder 116, personal computer 118, etc.). Register.

  FIG. 4 is a data structure diagram of the connection setting information storage unit 210. The access point ID column 230 indicates an access point ID that identifies each access point 112. The terminal ID column 232 indicates the terminal ID. The administrator ID column 234 indicates a user ID of a user set as an administrator of the area 140 that each access point 112 is in charge of.

  The administrator is not restricted in operating each information communication terminal 100. The administrator has the authority to change the setting of the connection setting information. The family authority column 236 indicates the authority of the user who is set as a family user to perform operation via the network for each information communication terminal 100. The family user is a registered user other than the administrator. Family users are subject to certain restrictions when operating each information communication terminal 100 via a network. The guest authority column 238 indicates the authority of the user who is set as a guest user to perform an operation via the network in each information communication terminal 100. The guest user operates each information communication terminal 100 via the network with the RFID card 108 in which a guest-specific user ID called a guest card (hereinafter referred to as “guest ID”) is recorded. That is, the guest user is treated as a special registered user. The guest user can operate the information communication terminal 100 as a special registered user. Guest users are also subject to certain restrictions via network operations. The address column 240 shows the administrator's e-mail address.

  When operating via the network using the information communication terminal 100 connected to the LAN 106, the user holds the information communication terminal 100 and his / her RFID card 108 over the non-contact IC memory reader / writer 110. The information communication terminal 100 connects to the network using the received communication setting information. Furthermore, the user ID acquired by the user ID acquisition unit 122 is used to connect to an arbitrary device (hard disk recorder 116, personal computer 118, etc.). The terminal registration unit 218 registers information for setting control in each device based on the connection setting information. That is, even if the information communication terminal 100 is connected to the network, the devices that can be operated are limited depending on the user ID.

  In the figure, the access point 112 with the access point ID “01” is permitted to connect the three information communication terminals 100 with the terminal IDs “04”, “06”, and “08”. For example, when the user who is the administrator of the user ID “02” performs an operation via the network using the information communication terminal 100 with the terminal ID “04”, the information communication terminal 100 uses the terminal ID “04” as the access point. Transmit to the access point 112 with ID “01”. According to the connection setting information, the access point 112 does not restrict data transmission / reception based on the terminal “04”. Subsequently, an arbitrary device is connected based on the user ID “02”. Therefore, the user who is the administrator can transmit and receive data to and from an external device after connecting the information communication terminal 100 to the access point 112. That is, the user can operate the information communication terminal 100 via the network without limitation.

  On the other hand, also when the family user with the user ID “01” operates the information communication terminal 100 via the network, the information communication terminal 100 transmits the terminal ID “04” to the access point 112 and sets the user ID “01”. Connect to any device based on. In the figure, only the reception of the operation via the network by the family user of the information communication terminal 100 with the terminal ID “04” is permitted. That is, only reception is registered in the gateway 104, and data can be received from the external device via the LAN 106, but data cannot be transmitted to the outside. In this case, an arbitrary device or gateway 104 to be connected to the information communication terminal 100 does not restrict data transfer to the device, but restricts data transfer from the device.

  When the access point 112 restricts data transfer, the access point 112 transmits the target terminal ID “04” to the connection management server 200. The mail transmission / reception unit 214 detects the electronic mail address of the user set as the administrator with reference to the address column 240 for the terminal ID “04”. In the figure, “axa@xxx.com”. This e-mail address may be, for example, an address of an administrator's mobile phone or laptop computer.

  The mail transmitting / receiving unit 214 automatically transmits an e-mail requesting permission for data transfer using the e-mail address as a transmission destination. When the mail transmission / reception unit 214 receives an answer indicating that the connection is permitted by the administrator, the mail transmission / reception unit 214 notifies the access point 112 of this. Thereby, the setting of the access point 112 is temporarily changed, and even a family user can transmit data to the outside via the terminal ID “04”. In this figure, the guest user cannot connect the information communication terminal 100 with the terminal ID “04” to the access point 112, but in this case as well, the connection is temporarily permitted if permitted by the administrator. .

  As a more specific example, for example, a case where a user refers to an image stored in a personal computer by a digital camera having a network connection function or stores a photographed image is shown. At this time, the user holds the RFID card 108 and the digital camera over the non-contact IC memory reader / writer 110, and the digital camera reads the connection setting information and the communication setting information with the authority of the user ID of the RFID card 108, and the terminal information (terminal ID ). Here, the connection management server 200 transmits an e-mail in order to report a network connection to the administrator, and receives a reply from the administrator indicating that the connection is permitted. When the connection management server 200 receives the connection permission mail, the connection management server 200 registers the terminal information in the corresponding access point 112. The digital camera connects to the network using the read communication setting information, and further logs in to the personal computer using the read user ID. In this way, the digital camera refers to the stored image or stores the captured image.

  Referring to FIG. 1, the corresponding access point 112 at this time determines whether or not the digital camera is connected to the network. When the connection permission mail is received from the administrator, it is possible to connect to the network, and if the user ID has the login authority for the personal computer 118, the image data in the personal computer 118 can be transmitted and received. It becomes. On the other hand, when the connection permission mail is not received from the administrator, even if the user ID has the login authority to the personal computer 118, the network connection cannot be made. , Can not be used.

  In this way, whether or not the connection to the access point 112 is easily managed based on the terminal information (terminal ID), it is easy to prevent unauthorized access. In addition, the communication system 300 can be flexibly operated regardless of connection setting information set in advance by checking with an administrator using e-mail.

  FIG. 5 is a flowchart showing a processing process centered on the information communication terminal 100 when the information communication terminal 100 is connected to the LAN 106. When the user holds the information communication terminal 100 and the RFID card 108 over the contactless IC memory reader / writer 110, a user ID is transmitted from the RFID card 108 to the contactless IC memory reader / writer 110 (S10). The user ID acquisition unit 122 may acquire the user ID from the RFID card 108, and the opposite wireless communication unit 128 may transmit this. The communication unit 120 reads terminal information from the terminal information storage unit 126 (S12). The opposing wireless communication unit 128 transmits the read terminal information to the non-contact IC memory reader / writer 110 (S14).

  The opposing wireless communication unit 128 receives communication setting information from the connection management server 200 via the contactless IC memory reader / writer 110. If it cannot be received within the predetermined time (N in S16), the process ends as a connection failure. When the user ID received via the non-contact IC memory reader / writer 110 is not the registered user's user ID, the connection availability determination unit 212 of the connection management server 200 rejects communication setting information transmission. When the opposite wireless communication unit 128 has successfully received the communication setting information from the connection management server 200 (Y in S16), the opposite wireless communication unit 128 stores the communication setting information in the communication setting information storage unit 124 (S18). The information communication terminal 100 executes a connection process to the access point 112 in charge of the area in each area 140. However, as described with reference to FIG. 4, if the connection is not permitted, the access point 112 rejects the connection.

  FIG. 6 is a flowchart showing the process of the connection management server 200 when the information communication terminal 100 is connected to the LAN 106. When the user holds the RFID card 108 and the information communication terminal 100 over the non-contact IC memory reader / writer 110, the user ID acquisition unit 222 receives the user ID via the non-contact IC memory reader / writer 110 (S30). Similarly, the terminal information acquisition unit 220 receives the terminal ID via the non-contact IC memory reader / writer 110 (S32). The connection possibility determination unit 212 determines whether or not the user ID is a registered user's user ID, and determines whether or not the information communication terminal 100 can be connected by the user (S34). When the connection is permitted (Y in S36), the terminal registration unit 218 reads and registers connection setting information such as a terminal ID related to the information communication terminal 100 from the connection setting information storage unit 210 with respect to each access point 112 ( S44). Next, the communication setting information generation unit 216 generates communication setting information that is a setting for the information communication terminal 100 to connect to the LAN 106 (S46). The communication setting information transmitting unit 224 transmits the communication setting information from the non-contact IC memory reader / writer 110 (S48).

  On the other hand, if the connection is not permitted in S36 (N in S36), the terminal registration unit 218 registers the terminal ID of the information communication terminal 100 in each access point 112 as the information communication terminal 100 that is not permitted to connect (S42). ). As a result, the information communication terminal 100 cannot be connected to any access point 112 of the LAN 106, and measures are taken so that the information communication terminal 100 is not illegally connected to the LAN 106.

  The present invention has been described above based on the embodiments. According to the present embodiment, setting for connecting to a network can be easily performed by a user interface that does not burden the user such as RFID. Further, by recognizing the user of the information communication terminal 100 based on the user ID, the information communication terminal 100 can be controlled according to the user.

  The present invention has been described above based on the embodiment. The present invention is not limited to this embodiment, and various modifications thereof are also effective as aspects of the present invention.

In the present embodiment, the connection possibility determination unit of the connection management server 200 is described as not permitting the connection of the information communication terminal 100 unless the user who has accessed the non-contact IC memory reader / writer 110 is a registered user or a guest user. did.
Apart from this, the information communication terminal 100 may be connectable to the wireless LAN 106 regardless of whether the accessing user is a registered user or a guest user. The terminal information is temporarily registered in each access point 112, and communication setting information is transmitted to the information communication terminal 100 via the non-contact IC memory reader / writer 110.

  When the information communication terminal 100 transmits terminal information to the non-contact IC memory reader / writer 110, the connection management server 200 notifies the user registered in advance as an administrator that the connection has been established by e-mail. In this mail, the name of the connected user, the terminal name, etc. are described. The administrator confirms the e-mail and returns a message to that effect if the connection may be permitted. Or it is good also as permission by not replying for a predetermined time. When the administrator does not want to connect, the administrator transmits an e-mail indicating that it is not permitted in a predetermined form to the connection management server 200. When the connection management server 200 receives an e-mail indicating that the connection is not permitted from the administrator, the connection management server 200 controls the MAC address filter of each access point 112 and changes the setting so as to reject the connection of the information communication terminal 100. Also good. By such a method, access to the wireless LAN 106 by a user who is not permitted by the administrator can be restricted.

  In the present embodiment, the operation via the network for each information communication terminal 100 has been described as an object, but authority for each user may be determined for each function of each information communication terminal 100. For example, a user who can read only a part of data recorded in the hard disk recorder and a user who can read all of the data may be set. Thereby, the data which each information communication terminal 100 has can be finely controlled.
