Description

  The present invention relates to a wireless LAN system and a portable terminal device used therefor.

  Conventionally, in order to use a wireless LAN, it is necessary to apply for a provider in advance and make settings after user registration.

In addition, a method has been proposed in which barcode printing and a memory card are provided to the user, and the user can perform settings by using the card and perform communication with the wireless LAN base station.
JP 2004-207820 A

  However, the setting information read from the barcode printing or the memory card is independent, and only one limited use is possible according to the one setting information. Therefore, in order to provide a plurality of restriction type services, it is necessary to prepare a plurality of barcodes or the like according to the services, and it is difficult to diversify the services due to the complexity, and the services are rigid. Tended to be.

  In view of this situation, the present invention provides a wireless LAN system including a portable terminal device having a wireless LAN communication unit, and a server device for providing the portable terminal device with the portable terminal device and a wireless LAN environment. It is what we propose. The user can use the portable terminal device, for example, to read restricted usage information printed on a receipt issued at the time of purchase of a product or the like at a store, and to communicate in a wireless LAN environment based on the read usage information. Such a setting is automatically made. The server device can generate time-limited use information that is limited use information based on time information that defines a length of time during which the server device can use the wireless LAN environment. Based on the restricted usage information, it is determined whether to extend the time during which the wireless LAN environment can be used.

  The server device can also make a determination to limit the number of times the portable terminal device is used in the wireless LAN environment and the number of communication packets. Furthermore, the server device can determine whether the wireless LAN environment can be used based on the authentication information output from the portable terminal device. In addition, the portable terminal device can display information related to usage restrictions in the wireless LAN environment based on the restricted usage information.

  Furthermore, the restricted usage information can be read in conjunction with the payment using the electronic money payment function. At this time, the server device may determine whether the portable terminal device with an electronic money payment function can use the wireless LAN environment based on the authentication information.

  As described above, in the wireless LAN system and the portable terminal device according to any one or more of the present inventions, the user does not need to make settings for manual connection and is simple. . Furthermore, even if the time limit of one piece of restricted usage information (read-read restricted usage information) is likely to expire, if you purchase a product in addition, new restricted usage information (new restricted usage information) ) And the setting is changed based on these. It is advantageous that the connection can be continued without interruption when the time limit of the usage information with read restriction expires, so that the user does not need to perform complicated setting processing.

  In addition, when the server device determines to use the wireless LAN environment of the portable terminal device or to limit the number of communication packets, or based on the authentication information output from the portable terminal device, the wireless LAN In determining whether the environment can be used, it is possible to prevent unauthorized use of the wireless LAN by a person other than the user who purchased the product. Furthermore, when the portable terminal device displays information related to the use restriction of the wireless LAN environment based on the restricted use information, it is convenient for the user not to be disconnected unexpectedly.

  Furthermore, if restricted usage information can be read in conjunction with payment using the electronic money payment function, the user who purchased the product can be surely expected to use the wireless LAN system, and a medium such as a receipt can be used. Since it is not necessary, it will also save resources. In addition, at this time, when the server device determines whether the portable terminal device with an electronic money payment function can use the wireless LAN environment based on the authentication information, the user can authenticate the user while authenticating the user. It is beneficial to ensure the use.

  The best mode for carrying out each invention will be described below. Note that the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the spirit of the present invention.

  << Embodiment 1 >>

  <Embodiment 1: Overview> Embodiment 1 will be described. The present embodiment is a wireless LAN system including a portable terminal device having a wireless LAN communication unit and a server device for providing the portable terminal device and a wireless LAN environment to the portable terminal device.

  FIG. 1 shows an example of the concept of this embodiment. The figure shows a flow in which a user who has a portable terminal device can communicate in a wireless LAN environment by shopping for a product at a store. As a premise, the server device attaches information for using the wireless LAN environment to a receipt or the like according to the product purchased by the user, the purchase price, etc., and the wireless LAN environment is added to the user's mobile terminal device. provide.

  First, the server device generates restricted usage information that is information for using the wireless LAN environment (1). In the figure, an example is shown in which, when a user first purchases a hamburger, restricted use information indicating that the wireless LAN environment can be used for 30 minutes is included in a two-dimensional barcode and printed on a receipt.

  On the other hand, the user reads the restricted usage information using the portable terminal device (2). In the example, it is assumed that the two-dimensional barcode printed on the receipt is photographed and the restricted usage information is read. Next, a setting for using the wireless LAN environment is performed based on the read restricted usage information (3). In the case where the restricted usage information includes, for example, an ID code necessary for wireless LAN connection, access point information, etc. in addition to the available time, the portable terminal is based on these data. Settings are automatically made so that the device can communicate with the access point. Here, communication is possible using the wireless LAN environment for 30 minutes, but when this time expires, the connection is disconnected.

  However, when a plurality of restricted usage information is read, the setting is changed based on the already read restricted usage information that has already been read and the new restricted usage information that was read later (4). In other words, after purchasing a hamburger, if you purchase iced coffee, you can use the wireless LAN environment for 20 minutes. In that case, the restricted usage information that can be used for 30 minutes by purchasing the hamburger is the usage information with already read restriction. The restricted usage information that can be used for 20 minutes by purchasing iced coffee is the new restricted usage information. The setting is changed based on the limited usage information, and the wireless LAN connection time is extended for 20 minutes.

  The server device determines whether the portable terminal device can use the wireless LAN environment based on the restricted usage information (5). If it is determined that the portable terminal device cannot use the wireless LAN environment, such as when the time limit is exceeded, communication of the portable terminal device may be hindered by not providing the wireless LAN environment to the portable terminal device. it can. Conversely, if the determination result is a determination result indicating that the wireless LAN environment can be used, a wireless LAN environment in which the portable terminal device can be used is provided (6). The portable terminal device can communicate in a wireless LAN environment.

  <Embodiment 1: Configuration> FIG. 2 shows an example of functional blocks in the present embodiment. The “wireless LAN system” (0200) of this embodiment shown in FIG. 2 includes a “portable terminal device” (0210) and a “server device” (0220). The portable terminal device (0210) includes a “reading unit” (0211), a “setting unit” (0212), a “setting changing unit” (0213), and a “wireless LAN communication unit” (0214). The server device (0220) includes a “restricted usage information generation unit” (0221), a “determination unit” (0222), and a “wireless LAN environment providing unit” (0223).

  Each unit, which is a component of the present invention, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, hardware composed of a CPU, a memory, a bus, an interface, a peripheral device, and the like and software executable on these hardware are listed. be able to. Specifically, the functions of the respective units are realized by sequentially executing the programs developed on the memory, by processing, storing, and outputting data on the memory and data input through the interface. (The same applies throughout this specification.)

  The “wireless LAN system” (0200) includes a portable terminal device (0210) and a server device (0220). In the present invention, not only the wireless LAN system but also the portable terminal device alone can read the restricted usage information and perform settings for using the wireless LAN environment.

  First, a portable terminal device will be described. The “portable terminal device” (0210) is a portable terminal device that can perform communication using a wireless LAN. For example, a cellular phone, a PHS, a PDA, a notebook personal computer, and the like are assumed.

  The “reading unit” (0211) performs processing for reading restricted usage information. “Restricted use information” is information for using the wireless LAN environment. This information includes information indicating the time when connection is possible in a wireless LAN environment, an ID code necessary for wireless LAN connection, information on an access point, and the like. The restricted usage information is generated by a server device to be described later. The restricted usage information generated at that time is encoded and included in a barcode (one-dimensional or two-dimensional), RFID, or the like. Is assumed. In this case, processing for reading restricted usage information is performed by a scanning mechanism, a photographing mechanism, a communication mechanism (such as radio waves, infrared rays, and ultrasonic waves).

  The “setting unit” (0212) performs settings for using the wireless LAN environment in the wireless LAN communication unit (0214) based on the restricted usage information read by the reading unit (0211). The restricted usage information includes the ID code necessary for wireless LAN connection, access point information, etc. in addition to the available time, etc., so that the portable terminal device can access based on these data. Settings are made so that communication with the point is possible under predetermined restrictions. There is no need for the user to manually set, and the setting is performed automatically.

  When the reading unit (0211) reads a plurality of restricted usage information, the “setting change unit” (0213) converts the already-read restricted usage information already read and the new restricted usage information read later. Based on this, the setting in the setting unit (0212) is changed. For example, if you can acquire limited usage information that can be used for 30 minutes by purchasing a hamburger, the user can communicate for 30 minutes in a wireless LAN environment, but when it exceeds 30 minutes The connection is cut off. However, for example, when iced coffee is further purchased and the wireless LAN environment can be used for 20 minutes, the setting is changed, and the setting for enabling connection for 20 minutes is performed. At this time, the limited usage information that can be used for 30 minutes by purchasing a hamburger is the usage information with read restriction, and the limited usage information that can be used for 20 minutes by purchasing iced coffee is the new limited usage information. is there. The portable terminal device automatically changes the setting based on the restricted usage information.

  At this time, even if the additional purchase of iced coffee was 10 minutes after the purchase of the hamburger, it will be extended for 20 minutes after the 30-minute usable time of the first hamburger purchase has expired. It can be used for minutes. In addition, the purchase of iced coffee alone can be used for only 15 minutes, but since a hamburger has been purchased first, it may be extended for an additional 20 minutes.

  The “wireless LAN communication unit” (0214) performs communication in a wireless LAN environment. Communication in a wireless LAN environment includes connection to the Internet network and transmission / reception of mail. In principle, communication is not possible when the time limit for the restricted use information expires or when the server device does not provide a wireless LAN environment. Of course, in addition to the case where communication is not possible at all, processing may be performed so that communication is possible under predetermined restrictions. For example, when the time limit on usage information expires, communication can be performed at a reduced communication speed, communication can be made only with a predetermined homepage server, or multimedia information such as video, still image, and audio can be transmitted. This is processing such that communication is not possible, but only text can be communicated, or video can be communicated, but communication with reduced image quality is possible.

  The wireless LAN communication unit enables communication using the LAN environment by the setting by the setting unit described above. The setting here may be made for the wireless LAN communication unit, or may be set so that the setting is recorded in the setting unit in order to enable communication in the wireless LAN communication unit.

  In any case, this setting is determined by the ESSID (Extended Service Set) according to the reading of a barcode or the like at first (this is not limited to reading of a barcode but of course there are various methods and means). First, communication with the server device is enabled by setting the acquired ESSID and the like. Thereafter, a DHCP address is assigned to the mobile terminal device by a server device, etc., and this LAN environment may relay communication to the mobile terminal device using this address. Information for starting may be passed from the server device so that the mobile terminal device can use the LAN environment based on the information. For example, communication within the LAN environment is performed in an encrypted manner, and a key for the mobile terminal device to decrypt the encryption may be passed as information for starting this communication. It is also possible to pass the IP address for this communication, the DNS IP address, the gateway IP address, or the like. The information for starting the communication described here is not necessarily limited to the acquisition using the communication with the server device after acquiring the ESSID or the like. For example, information that is imprinted in advance together with a barcode or the like when acquiring the ESSID may be used. Of course, both may be mixed to obtain information for starting this communication. That is, the information for using the LAN environment may be either information included in a barcode or the like via the reading unit or information passed from the server, and there are various processes for making the LAN environment available. In the present invention, it is not limited to any one.

  Next, the server device will be described. The “server device” (0220) is a server device for providing a wireless LAN environment to the mobile terminal device (0210). This assumes a server device installed to provide a wireless LAN environment to a user who has purchased a product or the like.

  The “restricted usage information generation unit” (0221) generates the limited usage information. Restricted usage information includes the connectable time for using the wireless LAN environment, ID code necessary for connection, access point information, etc. In some cases, it is generated as an RFID. The connectable time in the wireless LAN environment may be set by a value calculated based on various variables using a specific function. Examples of the variable include a product purchased by the user, a purchase price, a store, a region, a purchase time, a store congestion, the number of connected terminals, a user ID, a user attribute, and the like.

  In addition, it is assumed that a barcode or the like including restricted usage information is printed on a receipt or a card that is issued when a product is purchased at a store. There is an advantage that the system of the present invention can be used in existing store facilities. Further, the restricted use information may be attached to the product itself or the product packaging. Specifically, stamping, printing, lower bills, and the like are applicable.

  The “determination unit” (0222) determines whether the mobile terminal device can use a wireless LAN environment based on a plurality of restricted use information. When it is determined that the portable terminal device cannot use the wireless LAN environment, such as when the time limit is exceeded, the communication of the portable terminal device can be prevented by disconnecting the connection.

  On the other hand, the “wireless LAN environment providing unit” (0223) can use the portable terminal device when the determination result of the determination unit (0222) is a determination result that the wireless LAN environment can be used. A wireless LAN environment is provided. The portable terminal device can communicate in a wireless LAN environment.

  <Embodiment 1: Process Flow> FIG. 3 shows an example of the process flow in the first embodiment. First, the server device generates restricted usage information for using the wireless LAN environment (limited usage information generation step S0301). Next, the portable terminal device performs processing for reading the restricted usage information (reading step S0302), and determines whether a plurality of restricted usage information has been read (whether the already-read restricted usage information has already been read). Reading judgment step S0303). If it is determined in the multiple reading determination step (S0303) that only one piece of restricted usage information has been read, the wireless LAN environment is used based on the restricted usage information read in the reading step (S0302). Is set (step S0304). On the other hand, when it is determined in the multiple reading determination step (S0303) that a plurality of restricted usage information has been read, the already read restricted usage information that has already been read, and the new restricted usage information that has been read later, The setting is changed based on the above (setting changing step S0305).

  On the other hand, the server device determines whether the mobile terminal device can use the wireless LAN environment based on a plurality of restricted usage information (determination step S0306). Thereafter, when the determination result in the determination step (S0306) is a determination result that the wireless LAN environment can be used, provision of a wireless LAN environment in which the portable terminal device can be used is executed (wireless LAN environment providing step S0307) and the process returns to the determining step (S0306). At this time, if it is a determination result that the wireless LAN environment cannot be used, the processing is terminated without providing the wireless LAN environment (wireless LAN environment providing end step S0308). In the portable terminal device, communication is performed in a wireless LAN environment (wireless LAN communication step S0309).

  The above processing can be executed by a program for causing a computer to execute, and the program can be recorded on a recording medium readable by the computer. (The same applies throughout the specification.)

  <Embodiment 1: Effect> The present embodiment is a wireless device including a portable terminal device having a wireless LAN communication unit, and a server device for providing the portable terminal device and a wireless LAN environment to the portable terminal device. It is a LAN system. The user can use the portable terminal device, for example, to read restricted usage information printed on a receipt issued at the time of purchase of a product or the like at a store, and to communicate in a wireless LAN environment based on the read usage information. Such a setting is automatically made. Even if the time limit of one restricted use information (read-read restricted use information) is likely to expire, if you purchase a product in addition, new restricted use information (new restricted use information) And the settings are changed based on these. Since the connection can be continued without disconnection when the time limit of the read-ready usage information expires, it is beneficial because the user does not need to perform complicated setting processing. In addition, if the barcode including restricted usage information is printed on a receipt issued at the time of purchase of a product or the like at a store, the system of the present invention can be used in existing store facilities. There are advantages.

(0421) includes “time information acquisition means” (0424) and “time-limited use information generation means” (0425).

  The “time information acquisition unit” (0424) acquires time information. “Time information” is information that defines the length of time that the portable terminal device can use the wireless LAN environment. Specifically, when the product is settled, time information can be acquired by calculating the available time in the wireless LAN environment according to the product, the purchase price, and the like.

  “Time-limited use information generating means” (0425) generates time-limited use information based on the time information acquired by the time information acquiring means (0424). The use information with time limit is information on the connectable time for using the wireless LAN environment in a time limit. Specifically, it may be information for specifying a predetermined time such as 20 minutes available, or may be information for specifying an end time such as available until 7 o'clock. When the predetermined time is given and the store closing time is exceeded, the latter case is assumed. The time-limited use information may be encoded and generated as a barcode (one-dimensional or two-dimensional), RFID, or the like. In addition, barcodes including usage information with time restrictions may be printed on receipts or cards issued at the time of purchase of products at stores, etc., for other products themselves or product packaging In some cases, it may be attached by a method such as engraving, printing, or tagging.

This is a wireless LAN system characterized by the above. Even if it is likely that the time limit for usage information with one time limit will expire, if you purchase additional products, you can continue to connect, so the sales of products will increase to extend the connection time. Since it can be expected, it can be said that there is a merit in stores that provide a wireless LAN environment.

  << Embodiment 3 >>

  <Embodiment 3: Overview> Embodiment 3 will be described. The present embodiment is a wireless LAN system characterized in that the server device determines whether to extend the time in which the wireless LAN environment can be used based on a plurality of pieces of time-limited use information.

  <Embodiment 3: Configuration> FIG. 5 shows an example of functional blocks in the present embodiment. The “wireless LAN system” (0500) of this embodiment shown in FIG. 5 includes a “portable terminal device” (0510) and a “server device” (0520).

Have.

  The “extension determination means” (0526) determines whether to extend the time during which the wireless LAN environment can be used based on a plurality of pieces of use information with time restrictions. For example, even if the time limit permitted by the read time limit use information that has already been read is exceeded, a new time limit is included that includes time information that can be used for a further 20 minutes after that. When the usage information is being read, the available time is extended and communication can be continued. On the other hand, when it is determined that the portable terminal device cannot use the wireless LAN environment, for example, when the time limit is exceeded, communication of the portable terminal device can be prevented by disconnecting the connection. The processing of each other part is the same as in the second embodiment.

  <Embodiment 3: Effect> This embodiment is characterized in that the server device determines whether to extend the time in which the wireless LAN environment can be used based on a plurality of pieces of use information with time restriction. It is. Time-limited usage information (new-time-limited usage information) newly acquired by purchasing products before the time limit of the time-limited usage information (read-time-limited usage information) expires As a result, the available time is extended and communication can be continued. At this time, the server device determines whether to extend the available time. As a result, the store can manage the use of the wireless LAN environment, and the occupation of the customer in the store for a limited time and the use of the wireless LAN environment by a third party other than the customer can be restricted.

  << Embodiment 4 >>

  <Embodiment 4: Overview> Embodiment 4 will be described. The present embodiment is a wireless LAN system characterized in that the server device determines whether or not the wireless LAN environment can be used based on authentication information output from the portable terminal device.

  <Embodiment 4: Configuration> FIG. 6 shows an example of functional blocks in the present embodiment. The “wireless LAN system” (0600) of this embodiment shown in FIG. 6 includes a “portable terminal device” (0610) and a “server device” (0620). The portable terminal device (0610) includes a “reading unit” (0611), a “setting unit” (0612), a “setting changing unit” (0613), a “wireless LAN communication unit” (0614), and The server device (0620) includes a “restricted usage information generation unit” (0621), a “determination unit” (0622), and a “wireless LAN environment providing unit” (0621). 0623).

  The “authentication information output unit” (0615) outputs authentication information to the server device based on the setting information in the setting unit (0612). “Authentication information” is information including a LAN environment providing identifier and terminal device identification information in association with each other. The “terminal device identification information” is information for identifying a portable terminal device that can use the LAN environment, and corresponds to a number that can uniquely identify the portable terminal device, such as a telephone number. On the other hand, the “LAN environment provision identifier” is information for identifying use provision to a portable terminal device in a wireless LAN environment for each provision. Or, a serial number assigned in order when a wireless LAN environment is provided.

  The “determination unit” (0622) makes the determination based on both the LAN environment provision identifier of the authentication information and the terminal device identification information. FIG. 7 is a diagram illustrating an example of the flow of determination processing based on authentication information. In the upper part of the figure, the flow from when the portable terminal device A outputs authentication information to the server device and receives authentication is shown. As a precondition for authentication, the mobile terminal device A reads the restricted usage information from the barcode printed on the receipt obtained by purchasing the hamburger, and the setting for using the wireless LAN environment is completed. ing. Here, based on the setting information at the time of setting, the portable terminal device A includes the telephone number “090-111-2222”, which is the terminal device identification information, and the LAN environment provision identifier “300” in association with each other. The authentication information is output to the server device. On the other hand, for example, the server device performs authentication by comparing the LAN environment provision identifier held at the time of payment at the time of product purchase with the LAN environment provision identifier of the authentication information output from the portable terminal device A. . If the authentication is suitable, a wireless LAN environment is provided so that the mobile terminal device A can be used.

  If the authentication does not match, it is possible that a third party who has not purchased the product picks up the receipt left by the user and reads the restricted usage information from the bar code printed on it. . If a legitimate user can use the wireless LAN for 30 minutes but disconnects the line using the wireless LAN for only 10 minutes, the third party can use it for 20 minutes immediately after the end. In addition, when a legitimate user interrupts use, if the count of available time is also interrupted, the third party can use it for 20 minutes thereafter. The flow for the third party portable terminal device B to output authentication information to the server device and receive authentication is shown in the lower part of the figure. Here, the portable terminal device B authenticates the server device with authentication information that is associated with the telephone number “090-7777-8888”, which is terminal device identification information, and the LAN environment provision identifier “300”. Information will be output. On the other hand, the server apparatus authenticates that the portable terminal apparatus that already matches the LAN environment provision identifier “300” is the terminal identified by the terminal apparatus identification information “090-1111-2222” by the portable terminal apparatus A. Since the information is acquired, it is not determined that the wireless LAN environment can be used depending on the authentication information output from the portable terminal device B. That is, one receipt can prevent a plurality of people from using the wireless LAN illegally. The processing of each other part is the same as in the first embodiment.

  <Fourth Embodiment: Process Flow> FIG. 8 shows an example of a process flow according to the fourth embodiment. First, the server device generates restricted usage information for using the wireless LAN environment in a time-limited manner (limited usage information generation step S0801). Next, the portable terminal device performs processing for reading the restricted usage information (reading step S0802), and determines whether a plurality of restricted usage information has been read (whether the already-read restricted usage information has already been read). Reading judgment step S0803). If it is determined in the multiple reading determination step (S0803) that only one piece of restricted usage information has been read, the wireless LAN environment is used based on the restricted usage information read in the reading step (S0802). Is set for setting (setting step S0804). On the other hand, if it is determined in the multiple reading determination step (S0803) that a plurality of restricted usage information has been read, the already read restricted usage information that has already been read, and the new restricted usage information that has been read later, The setting is changed based on the above (setting changing step S0805). On the other hand, the server device determines whether the mobile terminal device can use the wireless LAN environment based on a plurality of restricted use information (determination step S0806). The process up to this point is the same as in the first embodiment.

  Next, in the portable terminal device, based on the setting information, a LAN environment providing identifier, which is information for identifying use provision to the portable terminal device in the wireless LAN environment for each provision, and the LAN environment can be used.
