  Embodiments of an information processing system, an information processing apparatus, and a program according to the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of the information processing system 1. The information processing system 1 includes an information processing device 2 and at least one access point 3. The information processing apparatus 2 and the access point 3 are connected to a wired communication network and can perform wired communication with each other.

  The information processing apparatus 2 is, for example, a device having a function as a printer and a function as a scanner. The information processing device 2 includes a wireless communication I / F 29 as an example of a first wireless communication device, and can directly wirelessly communicate with the mobile communication terminal 4. That is, the information processing apparatus 2 and the mobile communication terminal 4 can directly perform wireless communication on a one-to-one basis without using the access point 3. This direct wireless communication is realized by, for example, a Wi-fi direct function. For example, the information processing apparatus 2 prints image data received from the mobile communication terminal 4 or transmits scanned image data to the mobile communication terminal 4.

  Further, the wireless communication I / F 29 of the information processing apparatus 2 can switch between an active state and an inactive state. An active state refers to a state where the amount of power supplied to the wireless communication I / F 29 is sufficient to realize wireless communication, for example. In FIG. 1, a communicable range CA when the wireless communication I / F 29 is in an active state is indicated by a broken line. The inactive state refers to, for example, a state in which the amount of power supplied to the wireless communication I / F 29 is 0 or in the vicinity thereof. For this reason, the communicable range when the wireless communication I / F 29 is inactive is, for example, 0.

  The access point 3 is an example of a second wireless communication device and can communicate with the mobile communication terminal 4 wirelessly. Specifically, a connection (so-called infrastructure connection) to the wired communication network via the access point 3 is provided to the mobile communication terminal 4. The access point 3 stores in advance identification information such as the MAC address of the mobile communication terminal 4 that provides the infrastructure connection. The access point 3 receives the identification information from the mobile communication terminal 4 and provides the infrastructure connection to the mobile communication terminal 4 when the received identification information is registered in advance. On the other hand, if the received identification information is not registered in advance, infrastructure connection is not provided to the mobile communication terminal 4. That is, transfer of data other than identification information is restricted.

  In the present embodiment, the access point 3 transmits identification information of the mobile communication terminal 4 to the information processing apparatus 2. This operation will be described in detail later.

  The communicable range of the access point 3 overlaps with part or all of the communicable range CA when the wireless communication I / F 29 is active. Although FIG. 1 illustrates an example in which the communicable range of the access point 3 matches the communicable range CA when the wireless communication I / F 29 is active, the present invention is not limited to this mode. For example, the entire communicable range of the plurality of access points 3 may overlap with the communicable range CA when the wireless communication I / F 29 is active.

  The mobile communication terminal 4 is a portable terminal having a wireless communication function, and is, for example, a mobile phone (including a smartphone), a tablet computer, or a laptop computer.

  FIG. 2 is a diagram illustrating a configuration example of the information processing apparatus 2. The information processing apparatus 2 includes a control unit 21, a printer unit 25, a scanner unit 26, a wired communication I / F 28, and a wireless communication I / F 29.

  For example, the control unit 21 includes a calculation unit such as a CPU (Central Processing Unit) and a storage unit such as a RAM (Random Access Memory), and executes information processing according to a program. The program may be provided from a computer-readable information recording medium such as a CD-ROM, or may be provided via a communication line such as the Internet.

  The printer unit 25 is a unit that realizes a function as a printer, and forms an image on the surface of the medium in response to a command from the control unit 21. The scanner unit 26 is a unit that realizes a function as a scanner, and outputs image data read from the surface of the medium to the control unit 21.

  The wired communication I / F 28 is a device for performing wired communication with another device (for example, the access point 3) via a wired communication network. The wireless communication I / F 29 is a device for directly wirelessly communicating with the mobile communication terminal 4 as described above, for example, a device that realizes a Wi-fi direct function.

  By the way, a user of the mobile communication terminal 4 whose identification information of the mobile communication terminal 4 is registered in advance in the access point 3 (hereinafter referred to as a normal user) uses the information processing apparatus 2 via the access point 3. It is possible. On the other hand, a user of the mobile communication terminal 4 (hereinafter referred to as a temporary user) whose identification information of the mobile communication terminal 4 is not registered in advance in the access point 3 uses the information processing apparatus 2 via the access point 3. I can't. For this reason, in order for a temporary user to use the information processing apparatus 2, a Wi-fi direct function in which the information processing apparatus 2 and the mobile communication terminal 4 directly perform wireless communication is used.

  The conventional information processing apparatus is provided with a mechanical button for starting the Wi-fi direct function, and a temporary user can use the information processing apparatus up to a place where the information processing apparatus is installed. It was necessary to move and press the button, and the startup work was complicated. In addition, if the Wi-fi direct function is always activated, power consumption may be excessive.

  Therefore, the information processing apparatus 2 according to the present embodiment deactivates the wireless communication I / F 29 when it is detected via the access point 3 that the temporary user's mobile communication terminal 4 is within the communicable range CA. By switching from the state to the active state, the trouble of starting the Wi-fi direct function is reduced and the power consumption is reduced. Hereinafter, operations of the information processing apparatus 2, the access point 3, and the mobile communication terminal 4 will be described in detail.

  FIG. 3 is a diagram illustrating an example of the contents of a filter held by the access point 3. FIG. 4 is a diagram illustrating an operation example of the mobile communication terminal 4. FIG. 5 is a diagram illustrating a first operation example of the information processing apparatus 2.

  First, the search tool is activated in the mobile communication terminal 4 of the temporary user (S11 in FIG. 4). The search tool is activated, for example, when a temporary user intends to use the information processing apparatus 2. The search tool searches for access points 3 existing around the mobile communication terminal 4 (S12 and S13). The search for the access point 3 is performed based on, for example, the strength of the radio wave from the access point 3 received by the mobile communication terminal 4. Identification information such as SSID (Service Set Identifier) of the access point 3 extracted by the search tool is displayed in a list on the screen of the mobile communication terminal 4.

  Next, when the access point 3 is selected by the temporary user (S14). The mobile communication terminal 4 transmits its own MAC address to the selected access point 3. When the access point 3 receives the MAC address of the mobile communication terminal 4 of the temporary user, the access point 3 determines that it is not registered in advance, and stores it in the MAC address filter as an unregistered MAC address (see FIG. 3). . For this reason, infrastructure connection is not provided to the mobile communication terminal 4 of the temporary user, and transfer of data other than the process of registering the MAC address is restricted.

  The information processing apparatus 2 acquires a MAC address filter from the access point 3 (S21 in FIG. 5: function as an example of an acquisition unit). The acquisition of the MAC address filter can be realized by, for example, an 802.11 MIB of SNMP (Simple Network Management Protocol). Then, the information processing apparatus 2 determines whether there is a filter unregistered terminal in the acquired MAC address filter (S23). Thereby, the information processing apparatus 2 perceives that the mobile communication terminal 4 of the temporary user exists in the communicable range CA. Then, the information processing apparatus 2 activates the Wi-Fi direct function (S24). That is, the control unit 21 of the information processing device 2 generates a switching command for switching the wireless communication I / F 29 from the inactive state to the active state, and outputs the switching instruction to the wireless communication I / F 29 (function as an example of a generation unit). ). When the Wi-Fi direct function is activated, the wireless communication I / F 29 transmits a WPS (Wi-Fi Protected Setup) packet.

  On the other hand, when receiving the WPS packet, the mobile communication terminal 4 of the temporary user determines that there is an available information processing device 2 in the vicinity (S15: YES in FIG. 4), and displays that fact on the screen. Thereby, the temporary user perceives that there is an information processing apparatus 2 that can be used in the vicinity of the temporary user. Then, when the temporary user selects the use of the information processing apparatus 2 on the screen of the mobile communication terminal 4, WPS of the Wi-Fi direct function is executed (S16). As a result, the wireless connection is completed and the IP communication is performed. This is possible (S17 in FIG. 4 and S27 in FIG. 5). Thereby, the mobile communication terminal 4 of the temporary user can use services such as printing and scanning provided by the information processing apparatus 2 by operation on the mobile communication terminal 4 (S18 and S29).

  In the embodiment described above, the information processing apparatus 2 detects the mobile communication terminal 4 of the temporary user by periodically acquiring the MAC address filter from the access point 3, but is not limited to this aspect. . For example, when the access point 3 detects the mobile communication terminal 4 of the temporary user, the information processing apparatus 2 may be instructed to activate the Wi-Fi direct function.

  Further, the information processing apparatus 2 may authenticate the mobile communication terminal 4 of the temporary user using the acquired MAC address. FIG. 6 is a diagram illustrating a second operation example of the information processing apparatus. The same steps as those in the first operation example are denoted by the same reference numerals, and detailed description thereof is omitted. In the second operation example, the information processing apparatus 2 acquires the MAC address directly from the mobile communication terminal 4 of the temporary user after starting the Wi-Fi direct function (S25), and the MAC address is the access It is compared whether or not it matches the MAC address of the mobile communication terminal 4 of the temporary user acquired from point 3 (S26: function as an example of comparison means). If the MAC addresses match (S26: YES), the wireless connection is completed and IP communication is possible (S27).

  Further, the information processing apparatus 2 may activate the Wi-Fi direct function when the access point 3 receives the intention information indicating the use intention of the information processing apparatus 2 together with the identification information from the mobile communication terminal 4. For example, when the search tool is activated in the mobile communication terminal 4 (S11 in FIG. 4) indicates that the temporary user intends to use the information processing apparatus 2, the search tool is activated. The mobile communication terminal 4 may transmit the information indicating that the information is intended information to the access point 3.

  In the embodiment described above, the information processing apparatus 2 activates the Wi-Fi direct function when detecting the communication mobile terminal 4 of the temporary user. However, the present invention is not limited to this mode. The Wi-Fi direct function may also be activated when the communication mobile terminal 4 is detected.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art.
