JP 2007-325659 A

  In order for such a user's mobile terminal and the arcade game system to exchange game data, it is necessary to provide a wireless LAN router in the local area network in the arcade game system. If you do it, the burden on the store manager will increase.

  The inventor of the present application has developed a system in which a wireless LAN router is incorporated in an arcade game system. In such a system, the wireless LAN router is set by using a computer browser or a predetermined tool as usual. This is difficult to do and increases the burden on the store manager.

  The present invention has been made to solve the above-described problems. According to some aspects of the present invention, in a system in which a wireless LAN router is incorporated in an arcade game system, an arcade game system, a program, and an information storage medium capable of automating the setting of the wireless LAN router while ensuring security are provided. Can do.

(1) One aspect of the present invention is an arcade game system including a wireless LAN router that is communicably connected via a network and a host unit that sets the wireless LAN router. The wireless LAN router includes a wireless LAN router Sends an inquiry packet for searching for a host unit to be paired with the router to the router processing unit that performs router processing at a predetermined timing, and sends a response packet to the inquiry Upon reception, a router that detects the source device of the response packet as a host unit that is paired with its own device, and stores the identification information unique to the source device included in the response packet in the storage unit as host unit identification information Data for setting the side pairing processor and wireless LAN router function When receiving the packet, it is determined whether or not the packet transmission source including the setting data is a host unit paired with the own device based on the host unit specifying information stored in the storage unit, A setting data receiving unit that receives the setting data when it is determined, and the host unit transmits a setting data for setting a wireless LAN router function to the wireless LAN router, and a router setting control unit, When receiving an inquiry packet for searching for a host unit, a host-side pairing processing unit that performs control to transmit a reply packet including unique identification information that can identify the own device to the wireless LAN router of the transmission source, It is related with the arcade game system characterized by including.

  The present invention relates to a program that causes a computer to function as each of the above-described units. The present invention also relates to a computer-readable information storage medium that stores a program that causes a computer to function as each unit.

  The arcade game system is a game system including a business game casing installed in an amusement facility or the like. The arcade game system may include a wireless LAN router, a plurality of game machines, and other attached devices.

  The predetermined timing may be, for example, a power-on timing of the wireless LAN router, a reset timing, or a predetermined date and time, or a time cycle timing, for example.

  For example, the wireless LAN router may be a Wi-Fi router or the like.

The setting of the wireless LAN router function includes, for example, setting of configuration information and firmware information of the wireless LAN router, change of setting, update and the like. In addition, it may include setting of an IP address in a wireless LAN (local area network), setting when a DHCP (Dynamic Host Configuration Protocol) server function is used, setting of IP masquerade, and the like.
The wireless LAN router may broadcast an inquiry packet for searching for a host unit to be paired with the own device to a device in the same local network as the own device.

  The host unit may transmit a response packet including unique identification information that can identify the own device to the wireless LAN router by unicast.

  According to the present invention, in a system in which a wireless LAN router is incorporated in an arcade game system, setting of the wireless LAN router can be automated while ensuring security.

(2) In this arcade game system, program, and information storage medium, the wireless LAN router may be provided in the same casing as the host unit.

  For example, a host unit control board and a wireless LAN router board may be stored in the host unit housing. The host unit control board and the wireless LAN router board may share a power source.

  When the host unit functions as a game machine, the game board may also perform processing for host unit control.

(3) In this arcade game system, program, and information storage medium, the host unit may function as a game machine constituting the game system.

  At least one game machine constituting the game system may have a function as a host unit.

(4) In the arcade game system, the program, and the information storage medium, the host-side pairing processing unit is based on predetermined identification information assigned to the own device and other devices in the same local network as the own device. A wireless LAN router that is a transmission source of the inquiry packet when it is determined that the wireless device is a host unit to be paired, including a determination unit that determines whether the wireless device is a host unit that is paired with the wireless LAN router On the other hand, a reply packet including unique identification information that can identify the own device may be transmitted.

  Whether the host device is a host unit paired with the wireless LAN router may be determined, for example, at a timing when an inquiry packet is received or when the host unit is turned on.

  The predetermined identification information (number, symbol) used when determining whether or not the host device is a host unit paired with the wireless LAN router may be the same as the unique identification information included in the reply packet. An ID unique to the device may be used.

  Each host unit may incorporate a determination routine for determining whether the host device is a host unit that is paired with the wireless LAN router. In this way, when there are a plurality of host units in the game system, whether each host unit is a host unit to be paired with the wireless LAN router based on the same algorithm and based on predetermined identification information. Since the determination is made, the host units to be paired can be uniquely determined by all the host units.

(5) In this arcade game system, program, and information storage medium, the router-side pairing processing unit receives a response packet to an inquiry packet for searching for a host unit from a plurality of devices in the same local network as the own device. Then, based on the reception timing of the reply packet or a predetermined algorithm, or one device may be selected at random and determined as a host unit to be paired with the own device.

  The wireless LAN router may transmit an acknowledgment signal (for example, an Ack signal) to the host unit determined as the host unit to be paired with the own router. The host unit that has received the confirmation response signal can recognize that the own unit is the host unit of the wireless LAN router.

(6) In the arcade game system, the program, and the information storage medium, the router processing unit may stop the wireless LAN router process when the host unit cannot be detected.

The wireless LAN router process may be in a stopped state as long as it does not function as a router, such as a state where routing processing is not performed, a state where radio waves are not emitted, or a state where wireless is not accepted.
For example, if another wireless LAN router and host unit are already paired in the same local area network, the host unit stores the specific information of the wireless LAN router (for example, the serial number received in the packet). In addition, if the wireless LAN router specific information included in the newly received inquiry packet does not match the stored wireless LAN router specific information, the reply packet may not be transmitted. In such a case, the other wireless LAN routers cannot receive the reply packet, and may not be detected by the host unit. In this way, when a plurality of wireless LAN routers are included in the same local area network, the wireless LAN router previously paired with the host unit is connected to the wireless LAN router (active wireless LAN router) in the local area network. Can function as.

(7) In this arcade game system, program, and information storage medium, the router-side pairing processing unit stores the host unit specifying information in a nonvolatile storage unit, and receives a reset or update request for the host unit specifying information. If the request source is not a paired host unit based on the host unit identification information stored in the non-volatile storage unit, it is determined whether or not the request source is a paired host unit. May not allow a reset or update request for the host unit identification information.

  In this way, it is possible to prevent the host unit specifying information from being rewritten from other than the paired host units, so that security can be enhanced. However, for example, if a host unit that has already been paired does not exist in the local network for some reason (such as a failure) and you want to reset the pairing, it may not be permitted. Can be handled by forcibly resetting the wireless LAN router.

  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Configuration 1-1. Arcade Game System FIG. 1 shows an example of a functional block diagram of the arcade game system of the present embodiment. Note that the arcade game system of this embodiment may have a configuration in which some of the components (each unit) in FIG. 1 are omitted.

  The arcade game system 1 of the present embodiment is an arcade (business-use) game system 1 including a wireless LAN router 10 and a host unit 20-h that are communicatively connected via a local area network 30. The arcade game system 1 is an arcade game system (a game system including at least one game machine) and is installed at an amusement spot such as a game center or an amusement park and collects a fee for each play. It is a game system. For example, an arcade game system may be used in which n game machines are connected for communication so that a plurality of players can enjoy a multiplayer game. The arcade game system may include not only a game machine operated by the player but also an accessory device such as a monitor and a console.

  The wireless LAN router 10 exists between user terminals having a function of performing wireless communication with the arcade game system 1 (see 90 in FIG. 2, a portable game machine or a personal computer having a wireless communication function). It suffices to have a routing function for wireless packets transmitted and received in the local area network 30 including a wireless local area network (LAN) (see 80 in FIG. 2). The wireless LAN router 10 may be connected to a wide area network such as an external Internet (may have a function as a wireless LAN access point) or other routers in the facility. May be connected.

  The wireless LAN router 10 includes a router processing unit 12 that performs wireless LAN router processing.

  The router processing unit 12 may analyze and transfer a part of the protocol of the network layer (third layer) or the transport layer (fourth layer) in the OSI reference model, for example. A route selection process may be performed to determine which route should be used for transfer.

  Note that a router is a device for performing transmission path control and relaying of transmission packets between a plurality of networks, and is roughly divided into a local router and an access router depending on the application. A local router is a router that interconnects a LAN (Local Area Network), and an access router is a router that connects a WAN (Wide Area Network) and the LAN. A WAN is a network constructed and operated by a telecommunications carrier, and is provided to users in the form of a connection service. The WAN is composed of a relay network and an access line for connecting to the relay network. The access line includes an ISDN (Integrated Services Digital Network), a digital dedicated line, an ATM (Asynchronous Transfer Mode), and an ADSL (Asymmetric Bicycle). , FTTH (Fiber To The Home), and the like. As described above, the access router is a device for connecting the WAN and the LAN, and has an interface corresponding to each. Since the interface when using the WAN is an access line, the WAN side interface of the apparatus corresponds to the access line. Access lines include broadband lines (ADSL, FTTH, etc.), and access routers corresponding to these broadband lines as WAN-side interfaces are devices called broadband routers.

  The wireless LAN router 10 of the present embodiment only needs to have the function of a local router, but may have a function as an access router. That is, the router processing unit 12 performs processing as a local router, but may perform processing as an access router. In addition, when the wireless LAN router 10 of this embodiment has a function as a broadband router, firewall processing for security measures, VPN (Virtual Private Network) processing, and address conversion for converting a global address and a private address. Processing may be performed.

  When the wireless LAN router 10 transmits an inquiry packet for searching for a host unit to be paired with its own device to a device in the same local network as its own device at a predetermined timing, and receives a response packet to the inquiry, A router that detects the source device of the reply packet as a host unit that is paired with its own device, and stores the identification information unique to the source device included in the reply packet in the storage unit as host unit identification information A side pairing processing unit 14 is included.

  When the wireless LAN router 10 receives a packet including setting data for setting the wireless LAN router function, the packet transmission source including the setting data is based on the host unit specifying information stored in the storage unit. It includes a setting data receiving unit 14 that determines whether or not the host unit is a paired host and that receives the setting data when the host unit is determined.

  The setting data receiving unit 14 receives setting data for setting the wireless LAN router function from the paired host unit. The basic function of the router is to refer to a database called a routing table stored in the device, select an appropriate destination network for the received packet, and forward (forward) it to that network.

  In order to perform such processing, it is necessary to set an address, configuration information, and firmware information suitable for the network for each interface connected to the LAN when newly installing or changing settings. . The setting data received here may be an address suitable for the network, configuration information, and firmware information. In addition, a setting for using a DHCP (Dynamic Host Configuration Protocol) server function, an IP masquerade setting, or the like may be included.

  The setting data may be used for initial setting of the wireless LAN router, or may be used for setting change, update, or the like.

  The host unit 20-h may be a game machine that constitutes an arcade game system, or a device (for example, a monitor or console) attached to the game machine. Here, the case where the host device 20-h is a game machine constituting an arcade game system will be described as an example.

  The wireless LAN router 10 and the host unit 20-h may be provided in the same game machine housing.

  The host unit 20-h includes a router setting control unit 24 that transmits setting data for setting the wireless LAN router function to the wireless LAN router.

  When the host unit 20-h receives an inquiry packet for searching for a host unit, the host unit 20-h transmits a response packet (unicast) including unique identification information that can identify itself to the transmission source wireless LAN router. A host-side pairing processing unit 26 that performs control.

  The host-side pairing processing unit 26 determines whether or not the host device is a host unit that is paired with the wireless LAN router based on predetermined identification information assigned to the host device and other devices in the same local network as the host device. Includes a determination unit for determining, and when the host device is determined to be a host unit to be paired, includes a unique identification information capable of identifying the host device to the wireless LAN router that is a transmission source of the inquiry packet A reply packet may be transmitted.

  The router-side pairing processing unit 14 receives a response packet for an inquiry packet for searching for a host unit from a plurality of devices in the same local network as its own device, based on the reception timing of the response packet or a predetermined algorithm, Alternatively, one device may be selected at random and determined as a host unit to be paired with the own device.

  Also, the router processing unit 12 may stop the wireless LAN router process when the host unit cannot be detected.

  The router-side pairing processing unit 14 stores the host unit identification information in the nonvolatile storage unit, and when a reset or update request for the host unit identification information is received, the host stored in the nonvolatile storage unit Based on the unit identification information, it is determined whether or not the request source is a paired host unit. If the request source is not a paired host unit, the host unit identification information reset or update request is not permitted. You may do it.

2. Method 2-1 of this embodiment. Network Configuration Diagram FIG. 2 is an example of a network configuration diagram according to the present embodiment.

  In this embodiment, an in-store network as shown in FIG. 2 is configured for each amusement facility (store). A store router 310 is connected to an external wide area network such as the Internet. The store router 310 is assigned a global IP address.

  A global IP address is a unique IP address that communicates with the other party on the Internet and does not overlap with other addresses. In TCP / IP, an IP packet is transmitted or routed by identifying the other party. Is required. A certain range of IP addresses are assigned as private IP addresses to computers in the LAN, and global IP addresses are assigned only to devices that connect the LAN and the WAN.

  The store router 310 may function as a DHCP server having a function of providing setting information by DHCP, which is a protocol that automatically assigns necessary information such as an IP address to a computer that is temporarily connected to a network such as the Internet. . The DHCP server contains information necessary for connecting to the network, such as the IP address of the gateway server and DNS server, the subnet mask, and the range of IP addresses that can be assigned to the client. Provide this information to the computer. When the connected computer disconnects the communication, the address is automatically collected and assigned to another newly connected computer.

  The game system dedicated router 330-1, the game system dedicated router 330-2, and the game system dedicated router 330-3 are assigned to each game system. Each device (game machine, router, etc.) in the game system is connected via a local area network, and is connected to a higher level network via a game system dedicated router assigned to the game system. The game system dedicated router may function as a DHCP server.

  Reference numerals 360-1 to 360-13 denote IP addresses assigned to the respective devices. x, y are fixed assignments for each store, p, q, r are fixed assignments for each game system, w is arbitrary or fixed assignment for each wireless LAN router, and a, b , C, to ~ are arbitrarily assigned by the DHCP server.

  The game system is a unit for installation and sales. For example, the game machine 1 (20-1), the game machine 2 (20-2), the game machine 3 (20-3), and the game machine 4 (20- 4) and the wireless LAN router 10 may be included. Here, the game machine 1 (20-1) functions as a host unit, and the wireless LAN router 10 and the game machine 1 (20-1) functioning as a host unit are provided in the same game machine housing 40. Good.

  A game for wireless LAN control is installed in advance in game machine 1 (20-1) functioning as a host unit.

  For example, in the case of a game system having four game machines 20-1 to 20-4 as components, four game machines 20-1 to 20-4 and at least one wireless LAN router (any one of the wireless LAN routers is One set of game system that may be housed in the game console's casing) will be sold and installed in units of this set. The wireless LAN router 10 and the game machine 1 (20-1) functioning as a host unit may be provided in the same game machine housing 40.

  Here, each game machine of the game machine 1 to the game machine 4 corresponds to a game case played by the player, and includes an operation unit, a game image display unit, and a game sound output unit, respectively. For example, in the case of a race game, a maximum of four players can enjoy a multiplayer game by operating their respective game machines.

  370-1 to 370-4 are unique identification information that can identify each machine, and for example, a unique ID assigned to all game machines that need to be connected to the game server can be adopted. .

  Here, a case where one set of game system includes one wireless LAN router will be described as an example. However, the present invention is not limited to this, and a case where one set of game system includes a plurality of wireless LAN routers, The case where a wireless LAN router is included is also within the scope of the present invention.

2-2. Pairing Process FIGS. 3 to 5 are diagrams for explaining the pairing process.

  When the power of the wireless LAN router 10 is turned on, the wireless LAN router 10 requests an IP address from the game system dedicated router 330-1 functioning as a DHCP server (see FIG. 3A). Upon receiving the request, the game system dedicated router 330-1 returns an IP address “192.168.P.a” (360-8) (see FIG. 3B). TCP / IP settings follow the contents of DHCP Ack.

  The wireless LAN router 10 transmits an inquiry packet for searching for a host unit to be paired with the local area network in the game system by UDP (User Datagram Protocol) broadcast ((c) in FIG. 4). reference).

  UDP (User Datagram Protocol) is one of the protocols used on the Internet, etc., and is mainly implemented on the IP protocol and corresponds to the transport layer of the OSI reference model. Unlike TCP, it is connectionless and does not perform delivery confirmation.

  In the inquiry packet, the model name of the wireless router, serial number, firmware version, contents of Config, and unique identification information that can identify the paired host unit (not set during new pairing) At least one of

  Here, Config is the setting information of the wireless LAN router, and information for routing (determining the route of the packet), for example, definition of routing protocol (routing table, filtering, etc.), interface definition, router itself Or the like. The contents of Config may be given as a fingerprint value (a hash value obtained by applying Config to a hash function).

  Since the inquiry packet from the wireless LAN router 10 is broadcasted to each of the devices 20-1 to 20-4 and 330-1 constituting the local area network, a host unit that can be paired with the wireless LAN router (here, When the wireless LAN router control program 20-1 is installed on the game machine 1 in advance, upon receiving the inquiry packet, 20-1 transmits a response packet to the wireless LAN router 10 that is the inquiry packet transmission source (FIG. 4). (See (d)). The reply packet includes unique identification information 370-1 that can identify the host unit. The reply packet may include a firmware version requested from the wireless LAN router 10 and a fingerprint value of requested configuration information (Config). Since the other devices 330-1, 20-2, 20-3, and 20-4 do not have a function as a host unit, the received inquiry packet is ignored.

  The wireless LAN router 10 that has received the response packet stores, as host unit identification information, unique identification information 370-1 that can identify the host unit included in the received response packet (may be a non-volatile storage unit). (See (e) of FIG. 4). An acknowledgment packet is transmitted to the game machine 1 (20-1) serving as the host unit (see (f) of FIG. 5).

  If the host unit identification information is already held (stored in the nonvolatile storage unit), the unique identification information included in the received reply packet is different from the held host unit identification information. In this case, the reply packet is ignored and the above processing is not performed.

  If the wireless LAN router 10 does not receive a reply packet within a certain time after transmitting the inquiry packet, the series of procedures may be stopped, and an error display may be issued to stop.

  For example, when the response packet includes the firmware version requested from the wireless LAN router and the fingerprint value of the requested configuration information (Config), these are the firmware version of the own device and the configuration information (Config). Alternatively, if these fingerprint values do not match, a new version may be requested.

The host unit 20-1 that has received the confirmation response signal receives firmware or configuration information (config) from the host when the firmware is equal to or less than the requested value, configuration information (Config), or if these fingerprint values do not match. Control for transmitting setting data of (Config) and writing to the wireless LAN router may be performed. If rewriting is not necessary, a packet for enabling wireless communication is transmitted from the host side, and wireless LAN communication is started (see (g) of FIG. 5).
In this way, even in an environment where it is difficult to identify a wireless LAN router by IP address, such as in a LAN where an IP address is distributed by DHCP, the host unit can identify and control the wireless LAN router to be controlled. it can.

  When the wireless LAN router 10 and the host unit 20-1 are already paired, for example, when the host unit specifying information is stored in the nonvolatile storage unit, the processes (b) to (g) are omitted. May be. However, in order to confirm that the pairing partner exists in the local network, even when the host unit identification information is stored in the nonvolatile storage unit, at power-on or at a predetermined timing, (c) to (g ) May be performed. For example, the host unit may not exist in the local network for some reason.

  When the wireless LAN router 10 and the host unit 20-1 are provided in the same game machine housing 40, it is rarely moved separately, but the wireless LAN router and the host unit exist separately. If the wireless LAN router is stored in a game chassis different from the host unit, the host unit may not exist in the local area network.

  In addition, when the host unit identification information is stored in the nonvolatile storage unit, the processes (c) to (g) are performed, and the unique identification information of the reply packet received in (d) is stored in the nonvolatile storage unit. When the received host unit identification information does not match, error processing may be performed, or the host unit identification information may be replaced with unique identification information of the newly received response packet.

2-3. 9 includes a plurality of wireless LAN routers or a plurality of host units in the system. FIG. 9 is a diagram for explaining a case where a plurality of wireless LAN routers or a plurality of host units are included in the system.

  When the game system includes a plurality of game machine housings, and the plurality of game machine housings include a wireless LAN router, a game in which the game machine 1 housing 40-1 functions as a host unit here. 1 including a game machine 2 (20-2) and a wireless LAN router 10-2 in which the game machine 2 casing 40-1 functions as a host unit. The game system may form a local area network, or may form a local area network by connecting a plurality of game systems including one wireless LAN router.

  In such a case, a plurality of wireless LAN routers and a plurality of host units exist in one local area network. A description will be given of a pairing method in the case of adopting an operation rule in which only one pair of a wireless LAN router active in one local area network and a host unit controlling the same are adopted.

  A game machine that functions as a host unit may have a function of determining whether or not the own machine is an active host unit.

  The game machine (host unit), for example, at the timing of receiving an inquiry packet or when the host unit is turned on, to each of the other machines (game machine, etc.) in the same local network as the own machine. Based on the assigned identification information (number, symbol) assigned, it may be determined whether or not the own device can be an active host unit (a host unit paired with an active wireless LAN router).

  For example, the game machine (host unit) may have means for identifying another host unit in the local area network and obtaining predetermined identification information of the other host unit. The predetermined identification number may be identification information unique to the device used for the reply packet, or other information.

  To determine whether or not the host device is an active host unit (a host unit paired with an active wireless LAN router), the host unit has a determination routine, and the determination routine determines according to a predetermined algorithm. You may do it.

  For example, it acquires predetermined identification information (number, symbol) assigned to each of its own device and other devices (game machine, etc.) in the same local network as the own device, and the identification number is the predetermined condition (for example, the identification number is the most A device that satisfies (small) may be determined as an active host unit. For example, in FIG. 9, the device-specific identification information of game machines (devices installed with a wireless LAN router control program) 20-1 and 20-2 functioning as host units is “ABCD-0001” (370-1). ), “ABCD-0002” (370-2), “ABCD-0001” having a smaller value may be determined as an active host unit.

  In such a case, the game machine 1 (20-1) and the game machine 2 (20-2) use the same algorithm to determine whether or not the game machine 1 (20-1) is an active host unit. The game machine 2 (20-2) determines that the game machine 2 (20-2) is not an active host unit.

  Among the devices that have received the inquiry packet, devices that are not host units (devices in which the wireless LAN router control program is not installed) ignore the inquiry packet.

  In addition, among the devices that have received the inquiry packet, a device that functions as a host unit (a device in which a wireless LAN router control program is installed) is determined to be an active host unit. The response packet may be transmitted by unicast to the wireless LAN router that is the inquiry packet transmission source.

  In this way, even when there are a plurality of host units in the local area network, the host unit side determines whether or not the own unit is an active host unit and returns a response packet. The router side receives the reply packet only from the active host unit.

  In the above embodiment, the configuration for determining which host unit is active on the host unit side has been described. However, the present invention is not limited to this, and a configuration for determining which host unit is active on the wireless router side may be used. The wireless LAN router that has received the reply packet corresponding to the inquiry packet may determine an active host unit based on the reply packet. In such a case, when the wireless LAN router transmits an inquiry packet for searching for a host unit toward a device in the local area network, all the host units transmit a response packet.

  When the wireless LAN router 10-1 receives a response packet corresponding to the inquiry packet from a plurality of host units in the same local network as its own device, the wireless LAN router 10-1 is based on the reception timing of the response packet or a predetermined algorithm, or randomly (by lottery). ) One host unit may be selected and recognized as an active host unit (a host unit paired with the own device).

  In FIG. 9, for example, when the wireless LAN router 10-1 transmits an inquiry packet for searching for a host unit, the game machine 1 (20-1) and the game machine 2 (20-2) functioning as the host unit are connected to the wireless LAN router. A response packet is transmitted to 10-1.

  When the wireless LAN router 10-1 determines the active host unit based on the reception timing of the response packet, the transmission source of the response packet with the earliest reception timing may be determined as the active host unit. For example, when the wireless LAN router 10-1 transmits an inquiry packet, receives a response packet from the game machine 1 (20-1), and then receives a response packet from the game machine 2 (20-2), The game machine 1 (20-1) may be determined as an active host unit (a host unit paired with the wireless LAN router 10-1).

  When the wireless LAN router 10-1 determines an active host unit based on a predetermined algorithm, for example, based on an algorithm that determines an active host unit based on unique identification information included in the received reply packet. For example, the active host unit may be determined by detecting a game system local server in the same housing as the wireless LAN router.

  Further, the wireless LAN router 10-1 randomly selects one response packet from the response packets received within a predetermined period after transmitting the inquiry packet, and sets the transmission source of the selected response packet as an active host unit. May be determined as

  Since the wireless LAN router transmits an acknowledgment signal only to the active host unit, it is determined that the host unit that has received the acknowledgment signal within a predetermined period after transmitting the reply packet is an active host unit. May be.

When a plurality of wireless LAN routers are included in the system, each wireless LAN router may perform the processes (a) to (f) in FIGS. For example, if another wireless LAN router is already active in the same local area network, the host unit stores the specific information of the wireless LAN router, and the wireless LAN included in the newly received inquiry packet If the router specific information does not match the stored wireless LAN router specific information, the reply packet may not be transmitted. In such a case, since the other wireless LAN router cannot receive the reply packet, the function as the wireless LAN router may be stopped because the host unit cannot be detected. In this way, when a plurality of wireless LAN routers are included in the same local area network, the wireless LAN router that has been paired with the host unit first becomes an active wireless LAN router.
Note that the case where the function as a wireless LAN router is in a stopped state includes a state where routing processing is not performed, a state where radio waves are not skipped, a state where radio is not accepted, and the like.
In addition, when the wireless LAN router processing is in a stopped state, it is not always necessary to turn off the power supply. For example, other paired wireless LAN routers operating in the same LAN may be in the power-on state. It may be a case where it operates as a repeater (radio wave relay device).

  It is preferable in terms of security that the host unit identification information of the wireless LAN router should not be easily rewritten from other devices. Therefore, the wireless LAN router may store the host unit identification information in the nonvolatile storage unit so that the host unit identification information can be reset or updated only by the paired host unit. For example, when a host unit identification information reset or update request is received, it is determined whether the request source is a paired host unit based on the host unit identification information stored in the nonvolatile storage unit. If the request source is not a paired host unit, the host unit specifying information reset or update request may not be permitted.

  In this way, it is possible to prevent the host unit specifying information from being rewritten from other than the paired host units, so that security can be enhanced. However, for example, if a host unit that has already been paired does not exist in the local network for some reason (such as a failure) and you want to reset the pairing, it may not be permitted. Can be handled by forcibly resetting the wireless LAN router.

  A case will be described in which, when a pair of wireless LAN routers and host units that are active in the local area network are set, pairing between the host unit and the wireless LAN router cannot be established for some reason. For example, this is the case when one of them is no longer present in the local area network or when a failure occurs.

  For example, when the pair of active wireless LAN routers and host units that are active are not the same case as the wireless LAN router 10-1 and the host unit (game system local server) 20-2, The above-mentioned problem may occur when the local area network is disconnected. However, when the pair of wireless LAN routers and host units that are active are in the same housing such as the wireless LAN router 10-1 and the host unit (game system local server) 20-1, the housing itself is local. When both are disconnected from the area network, the problem is unlikely to occur. Therefore, the paired wireless LAN router and the host unit are preferably in the same casing.

3. Processing of this Embodiment FIG. 6 is a flowchart showing the flow of host unit detection processing of the wireless LAN router of this embodiment.

  When the wireless LAN router is turned on (step S10), it makes an IP address request to the DHCP server in the local area network (step S20).

  The IP address is received from the DHCP server, and the IP address of each device in the local area network is acquired. Further, the IP address included in the reply packet is set as the default gateway (step S30).

  Next, at a predetermined timing, an inquiry packet for searching for a host unit is broadcasted to a device in the same local network as the own device (step S40). If the specification is such that host unit detection processing is not performed when the host unit is already paired, the following processing may not be performed. For example, when host unit specifying information is stored in the nonvolatile storage unit, it may be determined that the host unit has already been paired.

  When a reply packet to the inquiry is received within a predetermined period from the transmission of the inquiry packet (step S50), the unique identification information included in the reply packet is stored as the host unit specifying information, and the response packet sender confirms the response. A packet is transmitted (step S60). Note that, when pairing has already been performed, if the unique identification information of the reply packet does not match the host unit specifying information stored in the nonvolatile storage unit, error processing may be performed. The specific information may be replaced with unique identification information of the response packet that has been newly received.

  FIG. 7 is a flowchart showing a flow of setting data setting processing of the wireless LAN router according to the present embodiment.

  When receiving the packet including the setting data (step S110), the wireless LAN router determines whether the packet transmission source is a paired host unit based on the host unit identification information (step S120).

  If the packet transmission source is a paired host unit (step S130), setting data is accepted (step S140). When the setting data is configuration information (Config) or firmware information, the configuration data (Config) or firmware information currently set in the wireless LAN router may be replaced or updated with the received contents. Further, in the case of other setting data, the other setting data currently set in the wireless LAN router may be replaced or updated with the received content.

  FIG. 8 is a flowchart showing a processing flow of the host unit according to the present embodiment.

  The host unit determines whether or not the host unit is a host unit that can be paired with the wireless LAN router, based on a predetermined identification ID assigned to the host device and other devices in the same local network as the host device (step). S210). The predetermined identification ID may be unique identification information.

  When an inquiry for searching for a host unit is received from the wireless LAN router, the following processing is performed (step S220).

  If the own device is a host unit that can be paired with the wireless LAN router (step S230), a reply packet including unique identification information that can identify the own device is transmitted to the transmission source wireless LAN router by unicast. Transmit (step S240).

  When an acknowledgment packet is received from the reply packet transmission destination (YES in step S250), it recognizes that its own device is a host unit paired with the wireless LAN router (step S260). In this case, information (for example, a serial number or other unique identification information included in the inquiry packet) specifying the pairing partner wireless LAN router may be stored.

  If no acknowledgment packet is received from the reply packet transmission destination within a predetermined period (YES in step S250), it is recognized that the own device is not paired with the wireless LAN router (step S270).

  The present invention is not limited to that described in the above embodiment, and various modifications can be made. For example, terms cited as broad or synonymous terms in the description in the specification or drawings can be replaced with broad or synonymous terms in other descriptions in the specification or drawings.

  For example, the wireless LAN router may be a Wi-Fi router or the like.
