  The flash EEPROM 902 stores various setting data in addition to a program executed by the CPU 901. For example, a routing table in which a destination of a packet received by the router device 900 is associated with information on a communication device that is a transfer destination of the packet is recorded.

  There are generally a plurality of NICs 904. For example, a broadband router used for connecting to the Internet in a home includes a LAN side NIC and a WAN (Wide Area Network) side NIC.

  When it is detected that the packet has arrived at the NIC 904, the CPU 901 confirms the destination of the packet and refers to the routing table recorded in the flash EEPROM 902 to determine the transfer destination of the packet. For example, when a packet that has reached the LAN side NIC is to be sent to the wide area communication network 700, the IP address and port number in the LAN of the terminal that sent the packet are assigned to the IP assigned to the WAN side NIC. The address and the dynamically assigned port number are rewritten and transferred from the WAN-side NIC to another router device.

On the other hand, in the game system 1 shown in FIG. 6, the first local communication network 500 is configured by the communication device 711, and the second local communication network 600 is also configured by the communication device 711.
That is, in FIG. 3, the first local communication network 500 and the second local communication network 600 are each composed of one different communication device, but the first local communication network 500 and the second local communication network 600 in FIG. 6. Is composed of one common communication device.

  In the game system 1 shown in FIG. 3, a packet sent from the first terminal 200 to the server device 400 passes through the communication devices 711 to 71n, and a packet sent from the second terminal 300 to the server device 400 communicates. It passes through the devices 721 to 72m and reaches the server device 400.

  On the other hand, in the game system 1 shown in FIG. 6, a packet sent from the first terminal 200 to the server device 400 passes through the communication devices 711 to 71n and is sent from the second terminal 300 to the server device 400. Passes through the communication devices 711 and 722 to 72 m and reaches the server device 400.

  Next, information included in packets transmitted from the first terminal 200 and the second terminal 300 to the server device 400 will be described. In the present embodiment, it is assumed that a protocol in which the information on the transmission source terminal and the information on the transmission destination terminal are added to the header part of the packet transmitted from the first terminal 200 and the second terminal 300 is used.

  In the game system 1 of FIGS. 3 and 6, the IP (Internet Protocol) address of the first terminal 200 is “a”, the port number is “x”, the IP address of the second terminal 300 is “b”, and the port number is “ y ”, the IP address of the server device 400 is“ C ”, the port number is“ Z ”, the IP addresses of the communication devices 711 to 71n are“ A1 ”to“ An ”, the port numbers are“ X1 ”to“ Xn ”, the communication Assume that the IP addresses of the devices 721 to 72m are “B1” to “Bm”, and the port numbers are “Y1” to “Ym”. Hereinafter, a combination of an IP address and a port number is referred to as “terminal identification information”.

When the IP address and the port number are set as described above, in FIG. 3 and FIG. 6, the terminal identification information “a: x” of the first terminal 200 is included in the header portion of the packet transmitted from the first terminal 200. ”And terminal identification information“ C: Z ”of the server device 400 are added.
Further, the terminal identification information “b: y” of the second terminal 300 and the terminal identification information “C: Z” of the server device 400 are added to the header portion of the packet transmitted from the second terminal 300.

  Next, a schematic configuration of the first terminal 200, the second terminal 300, and the server device 400 constituting the game system 1 will be described.

(Outline configuration of the first terminal)
As shown in FIG. 7, the first terminal 200 includes an information transmission unit 201 and is configured as follows.

The information transmission unit 201 transmits unique information 801 for identifying the first terminal 200 to the server device 400. The unique information 801 is, for example, a MAC address uniquely assigned to a LAN card included in the first terminal 200 or a product key of the first terminal 200. In the game system 1 of FIGS. 3 and 6, the information transmission unit 201 includes, for example, information on the transmission source of the packet (terminal identification information “a: x” of the first terminal 200) in the header portion of the packet, Packet including information on the destination (terminal identification information “C: Z” of the server device 400) and information on the MAC address “xx: xx: xx” of the first terminal 200 in the data portion of the packet. Is transmitted to the communication terminal 711.
Therefore, the CPU 101 and the NIC 109 cooperate to function as the information transmission unit 201.

  In general, when a packet is transmitted from the LAN via the Internet, the terminal identification information of the packet transmission source (first terminal) is dynamically assigned with the IP address assigned to the router device constituting the LAN. It is rewritten to the terminal identification information consisting of the specified port number. Therefore, the communication device 711 that has received the packet from the information transmission unit 201 rewrites the terminal identification information “a: x” of the transmission source to “A1: X1”, and transmits the packet to the next communication device 712 based on the routing table. Send. The communication devices 712 to 71n that have received the packet refer to the transmission destination of the packet and the routing table to sequentially transfer the packet to an appropriate transfer destination, and the packet transmitted by the first terminal 200 reaches the server device 400.

(Outline configuration of the second terminal)
As shown in FIG. 8, the second terminal 300 includes a reception unit 301 and a request transmission unit 302 and is configured as follows.

The accepting unit 301 accepts input of user identification information 802a for identifying the user of the second terminal 300. For example, the user identification information 802a is a user ID and a password. When starting the game, when the user inputs the user ID “XXX” and the password “xxxx” using a controller or the like provided in the video game device, the receiving unit 301 receives the input.
Therefore, the CPU 101, the interface 104, and the controller 105 cooperate to function as the receiving unit 301.

The request transmission unit 302 transmits a login request 802 specifying the user identification information 802a to the server device 400. That is, the login request 802 includes the user ID and password information input by the user. For example, in the game system 1 of FIG. 3 and FIG. 6, the packet transmitted from the request transmission unit 302 to the server device 400 includes the information of the user identification information 802a in the data portion of the packet, Information of the transmission source of the packet (terminal identification information “b: y” of the second terminal 300) and information of the transmission destination of the packet (terminal identification information “C: Z” of the server device 400) are included. Then, the request transmission unit 302 transmits the packet to the nearest communication device. That is, the request transmission unit 302 transmits the packet to the communication device 721 in the game system 1 of FIG. 3 and to the communication device 711 in the game system 1 of FIG.
Therefore, the CPU 101 and the NIC 109 cooperate to function as the request transmission unit 302.

  Upon receiving the packet from the request transmission unit 302, the communication device 721 (FIG. 3) rewrites the terminal identification information of the transmission source as “b: y” to “B1: Y1” or receives the packet from the request transmission unit 302 The communication device 711 (FIG. 6) rewrites “b: y” as “A1: X1” in the terminal identification information of the transmission source, and transmits the packet to the next communication device 722 based on the routing table. The communication devices 722 to 72 m that have received the packet refer to the transmission destination of the packet and the routing table, sequentially transfer the packet to an appropriate transfer destination, and the packet transmitted by the second terminal 300 reaches the server device 400.

(Outline configuration of server device)
As shown in FIG. 9, the server device 400 includes a storage unit 401, an information reception unit 402, a request reception unit 403, and a response transmission unit 404, and is configured as follows.

The storage unit 401 stores a pair of unique information 801 for identifying a terminal and user identification information 802a for identifying a user. The unique information 801 and the user identification information 802a stored in the storage unit 401 are registered in advance when the user purchases a game. For example, the storage unit 401 stores an authentication table 401a as illustrated in FIG. In the authentication table 401a, the MAC address 401a1 of the portable game device, the user ID 401a2 of the user who owns the portable game address, and the password 401a3 are registered in association with each other.
Therefore, the RAM 103 functions as the storage unit 401.

The information receiving unit 402 receives the unique information 801 transmitted from the first terminal 200. For example, in the game system 1 of FIG. 3 and FIG. 6, the information receiving unit 402 receives the information of the MAC address “xx: xx: xx” of the portable game device from the communication device 71n and the terminal of the communication device 711 as the transmission source. A packet including the identification information “A1: X1” is received.
Therefore, the CPU 101 and the NIC 109 cooperate to function as the information receiving unit 402.

The request receiving unit 403 receives the login request 802 transmitted from the second terminal 300. For example, in the game system 1 of FIG. 3, the request reception unit 403 receives information about the user ID “XXX” and the password “xxxx” as the user identification information 802 a from the communication device 72 m and the terminal identification of the communication device 721 as the transmission source. A packet including the information “B1: Y1” is received. Further, for example, in the game system 1 of FIG. 6, the request receiving unit 403 receives the information of the user ID “XXX” and the password “xxxx” as the user identification information 802a from the communication device 72m and the communication device 711 of the transmission source. A packet including terminal identification information “A1: X1” is received.
Therefore, the CPU 101 and the NIC 109 cooperate to function as the request receiving unit 403.

The response transmission unit 404 is configured such that (A) the difference between the time when the information reception unit 402 receives the unique information 801 and the time when the request reception unit 403 receives the login request 802 (hereinafter referred to as “reception time difference”) is a predetermined time. (B) a pair of received unique information 801 and user identification information 802a specified by the received login request 802 is stored in the storage unit 401, and (C) the first local communication network 500 and the first local communication network 500 If the two local communication networks 600 match, a response 803 permitting login is transmitted to the second terminal 300. On the other hand, when the reception time difference is longer than the predetermined time, when the unique information or the user identification information is not stored in the storage unit 401, the correspondence between the unique information and the user identification information is stored in the storage unit 401. If they are different, or if the first local communication network 500 and the second local communication network 600 do not match, the response 803 that permits login is not notified to the second terminal 300.
Therefore, the CPU 101 and the NIC 109 cooperate to function as the response transmission unit 404.

Here, the fact that the first local communication network 500 and the second local communication network 600 match each other means that the first local communication network 500 and the second local communication network 600 are configured by the same communication device, that is, reception. Means that the IP addresses of the transmission sources of the packets matched. Therefore, in the case of FIG. 3, the IP address of the transmission source of the packet transmitted from the first terminal 200 belonging to the first local communication network 500 is “A1”, and from the second terminal 300 belonging to the second local communication network 600. Since the source IP address of the transmitted packet is “B1”, it is determined that the first local communication network 500 and the second local communication network 600 do not match.
On the other hand, in the case of FIG. 6, the IP address of the transmission source of the packet transmitted from the first terminal 200 belonging to the first local communication network 500 is “A1”, and from the second terminal 300 belonging to the second local communication network 600. Since the source IP address of the transmitted packet is also “A1”, it is determined that the first local communication network 500 and the second local communication network 600 match.

  For example, if the predetermined time is 3 minutes, the difference between the time when the packet including the MAC address “xx: xx: xx” is received and the time when the packet including the user ID “XXX” and the password “xxxx” is received is Within 3 minutes, a pair of the MAC address “xx: xx: xx”, the user ID “XXX” and the password “xxxx” is registered in association with the authentication table 401a, and the MAC address “xx: xx: xx When the IP address of the transmission source of the packet including “” matches the IP address of the transmission source of the packet including the user ID “XXX” and the password “xxxx”, the response transmission unit 404 adds 2 includes the session ID assigned to the terminal 300, the terminal identification information “C: Z” of the transmission source server apparatus 400 and the transmission destination communication apparatus 7 in the header of the packet 1 of terminal identification information "B1: Y1" and transmits a packet containing. The server device 400 specifies all the session IDs for requests from the second terminal 300 after permitting login, and treats the requests as valid requests if the combination of the IP address of the communication device 721 and the session ID matches. Otherwise it is treated as an invalid request.

(Game system operation)
Hereinafter, operations performed by the game system 1 according to the first embodiment will be described. When the information processing apparatus 100 that realizes the first terminal 200, the second terminal 300, and the server apparatus 400 is turned on, the first terminal 200, the second terminal 300, and the server apparatus 400 may 2 is started. In the communication, the first terminal 200 performs the process (unique information transmission process) shown in the flowchart of FIG. 11, and the second terminal 300 performs the process (login request transmission process) shown in the flowchart of FIG. Performs the process (response transmission process) shown in the flowchart of FIG. Hereinafter, each process will be described.

(Unique information transmission process)
When the information processing apparatus 100 that realizes the first terminal 200 is powered on, the CPU 101 starts the unique information transmission process (FIG. 11).

  First, the CPU 101 acquires unique information 801 of the first terminal 200 (step S101). For example, information on the MAC address “xx: xx: xx” of the portable game terminal is acquired.

  Then, the information transmission unit 201 transmits unique information 801 for identifying the first terminal 200 to the server device 400 (step S102). For example, the information transmission unit 201 includes terminal identification information “a: x” of the transmission source first terminal 200 and terminal identification information “C: Z” of the transmission destination server device 400 in the header of the packet. The packet including the information of the MAC address “xx: xx: xx” of the first terminal 200 is transmitted to the communication device 711.

(Login request sending process)
When the information processing apparatus 100 that realizes the second terminal 300 is turned on, the CPU 101 starts a login request transmission process (FIG. 12).

  First, the CPU 101 determines whether or not there is an instruction to start a game by the user (step S201). When the CPU 101 determines that there is an instruction to start the game by the user (step S201; Yes), the CPU 101 displays a login screen for inputting the user identification information 802a on the screen provided in the second terminal 300 or the like. (Step S202). On the other hand, when the CPU 101 determines that there is no instruction to start the game by the user (step S201; No), the CPU 101 waits as it is.

Next, the reception unit 301 determines whether or not the user identification information 802a has been received (step S203). When the reception unit 301 determines that the user identification information 802a has been received (step S203; Yes), the request transmission unit 302 transmits a packet including the user identification information 802a to the server apparatus 400 as a login request 802 (step S203). S204).
For example, if the user inputs the user ID “XXX” and the password “xxxx”, the request transmission unit 302 includes the user ID and password information in the data portion of the packet, and transmits it in the header portion of the packet. A packet including the terminal identification information “b: y” of the original second terminal 300 and the terminal identification information “C: Z” of the destination server apparatus 400 is transmitted to the communication apparatus 721.

  On the other hand, when the reception unit 301 does not determine that the user identification information 802a has been received (step S203; No), the reception unit 301 waits while displaying the login screen.

(Response transmission processing)
When the information processing apparatus 100 that implements the server apparatus 400 is turned on, the CPU 101 starts a response transmission process (FIG. 13).

The request receiving unit 403 determines whether or not the login request 802 transmitted from the second terminal 300 has been received (step S301). When the request receiving unit 403 determines that the login request 802 has been received (step S301; Yes), the information receiving unit 402 determines whether the unique information 801 transmitted from the first terminal 200 has been received (step S301). S302). On the other hand, when the request receiving unit 403 does not determine that the login request 802 has been received (step S301; No), the server apparatus 400 stands by as it is.
For example, when the request reception unit 403 receives a packet including information of the user ID “XXX” and the password “xxxx” from the video game device, the information reception unit 402 receives the MAC address “of the portable game device from the portable game device. It is determined whether or not information “xx: xx: xx” has been received.

In step S302, when it is determined that the information reception unit 402 has received the unique information 801 (step S302; Yes), the response transmission unit 404 receives the time when the information reception unit 402 received the unique information 801, and the request reception unit 403. Obtains the time when the login request 802 is received, and determines whether or not the reception time difference is within a predetermined time (step S303).
For example, when the information reception unit 402 determines that the information of the MAC address “xx: xx: xx” of the portable game device is received from the portable game device, the response transmission unit 404 receives the MAC address “xx: xx: xx”. The difference (reception time difference) between the time when the packet including the information “” and the time when the packet including the user ID “XXX” and the password “xxxx” is received is obtained, and the reception time difference is a predetermined time (for example, 3 It is determined whether it is within minutes).

On the other hand, when the information reception unit 402 does not determine that the unique information 801 has been received (step S302; No), the response transmission unit 404 obtains the time when the request reception unit 403 received the login request 802, and the time It is determined whether or not the difference from the current time is within a predetermined time (step S308). If the response transmission unit 404 determines that the difference between the time when the login request 802 is received and the current time is within a predetermined time (step S308; Yes), the response transmission unit 404 transmits the login request 802 to the second terminal 300. The fact that the unique information 801 has not been received is notified (step S309). Then, the process returns to step S302, and the information reception unit 402 determines again whether the unique information 801 has been received.
For example, assuming that the predetermined time is 3 minutes, the time when the packet including the user ID “XXX” and the password “xxxx” is received is 15:01, and the current time is 15:02, a response transmission unit 404 notifies the video game device that the MAC address of the portable game device has not been received, and the information receiving unit 402 determines again whether a packet including the MAC address has arrived.

On the other hand, when the response transmission unit 404 determines that the difference between the time when the login request 802 is received and the current time is not within the predetermined time (step S308; No), the second terminal 300 is authenticated for login. The fact that it was not successful is notified (step S310).
For example, if the predetermined time is 3 minutes, the time when the packet including the user ID “XXX” and the password “xxxx” is received is 15:01, and the current time is 15:04, the response transmission unit 404 notifies the video game device that the login authentication was not successful.

In step S303, when the response transmission unit 404 determines that the reception time difference is within the predetermined time (step S303; Yes), the response transmission unit 404 acquires the user identification information 802a included in the packet of the received login request 802, and the storage unit With reference to the user ID 401a2 and password 401a3 registered in the authentication table 401a stored in 401, it is determined whether or not the user identification information 802a is correct (step S304). On the other hand, when the response transmission unit 404 determines that the reception time difference is not within the predetermined time (step S303; No), the response transmission unit 404 notifies the second terminal 300 that the login authentication has not been successful (step S310).
For example, the predetermined time is 3 minutes, the time when the packet including the information of the MAC address “xx: xx: xx” is received is 15:00, the time when the packet including the user ID “XXX” and the password “xxxx” is received Is 15:01, since the reception time difference is 1 minute, the response transmission unit 404 determines that the reception time difference is within a predetermined time, and the set of the user ID “XXX” and the password “xxxx” is correct. Determine whether or not. On the other hand, the time when the packet including the information of the MAC address “xx: xx: xx” is received is 15:00, and the time when the packet including the user ID “XXX” and the password “xxxx” is received is 15:04. Then, since the reception time difference is 4 minutes, the response transmission unit 404 determines that the reception time difference is not within the predetermined time, and notifies the video game device that the login authentication was not successful.

When the response transmission unit 404 determines that the user identification information 802a is correct (step S304; Yes), the response transmission unit 404 determines whether a pair of the unique information 801 and the user identification information 802a is stored in the storage unit 401 (step S304). S305). On the other hand, if the response transmission unit 404 does not determine that the user identification information 802a is correct (step S304; No), the response transmission unit 404 notifies the second terminal 300 that the login authentication has not succeeded (step S310).
For example, when the user ID “XXX” and the password “xxxx” are received, the response transmission unit 404 refers to the authentication table 401a, determines that the set of the user ID “XXX” and the password “xxxx” is correct, It is determined whether a pair of the MAC address, the user ID, and the password is stored in the authentication table 401a. On the other hand, when the user ID “XXX” and the password “yyy” are received, the response transmission unit 404 determines that the combination of the user ID “XXX” and the password “yyy” is incorrect, and authenticates login to the video game device. Notify that was not successful.

In step S305, when the response transmission unit 404 determines that the pair of the unique information 801 and the user identification information 802a is stored in the storage unit 401 (step S305; Yes), the first local communication network 500 and the second It is determined whether or not the local communication network 600 matches (step S306). On the other hand, when the response transmission unit 404 determines that the pair of the unique information 801 and the user identification information 802a is not stored in the storage unit 401 (step S305; No), the login authentication to the second terminal 300 is successful. The fact that there was no notification is sent (step S310).
For example, when the user ID is “XXX”, the password is “xxxx”, and the MAC address transmitted from the portable game device is “xx: xx: xx”, the response transmission unit 404 includes the MAC address, the user ID, It is determined that the password pair is stored in the authentication table 401a, and it is determined whether or not the LAN to which the portable game device belongs and the LAN to which the video game device matches. On the other hand, when the user ID is “XXX”, the password is “xxxx”, and the MAC address transmitted from the portable game device is “yy: yy: yy”, the response transmission unit 404 receives the MAC address “yy: yy”. : yy ”, the user ID“ XXX ”and the password“ xxxx ”are determined not to be stored in the authentication table 401a, and the video game apparatus is notified that the login authentication has not been successful.

In step S <b> 306, if the response transmission unit 404 determines that the first local communication network 500 and the second local communication network 600 match (step S <b>306; Yes), the response transmission unit 803 transmits a response 803 permitting login to the second terminal 300. (Step S307). On the other hand, if the response transmission unit 404 determines that the first local communication network 500 and the second local communication network 600 do not match (step S306; No), the fact that the login authentication to the second terminal 300 has not succeeded. Is notified (step S310).
For example, when the source IP address of the packet including the MAC address matches the source IP address of the packet including the user ID and the password, the response transmission unit 404 and the second local communication network 500 It is determined that the network 600 matches. That is, in the case of FIG. 6, the transmission source IP address of the packet (unique information 801) including the MAC address transmitted by the portable game device (first terminal 200) is “A1”, and the video game device (second terminal 300). Since the transmission source IP address of the packet including the user ID and password transmitted by “) is“ A1 ”, the response transmission unit 404 determines that the LAN to which the portable game device belongs and the LAN to which the video game device belongs are the same. Then, a response permitting login is transmitted to the video game device. On the other hand, in the case of FIG. 3, the transmission source IP address of the packet (unique information 801) including the MAC address transmitted by the portable game device (first terminal 200) is “A1”, and the video game device (second terminal 300). ) Transmitted from the packet including the user ID and password is “B1”, the response transmission unit 404 determines that the LAN to which the portable game device belongs does not match the LAN to which the video game device belongs. Then, the video game device is notified that the login authentication was not successful.

  According to this embodiment, it is not necessary to distribute a new device by performing user authentication using information of a terminal possessed by a user other than a terminal that plays a game, and each time authentication is performed. Since it is not necessary to input information of the terminal, authentication can be performed safely and easily.

(Embodiment 2)
In the second embodiment, a login authentication method in the case where each of the first local communication network to which the first terminal belongs and the second local communication network to which the second terminal belongs is configured by a plurality of communication devices will be described.

In the response transmission unit 404, (A) the difference (reception time difference) between the time when the information reception unit 402 receives the unique information 801 and the time when the request reception unit 403 receives the login request 802 is within a predetermined time. B) A pair of the received unique information 801 and the user identification information 802 a specified by the received login request 802 is stored in the storage unit 401, and (D) the unique information 801 passes through until reaching the server device 400. Any of the communication devices 501, 502, 711 to 71 n that are within a predetermined number of hops and the communication devices 601, 602, 721 to 72 m through which the login request 802 has reached the server device 400. If any of the communication devices within a predetermined number of hops matches, the first local communication network 500 and the second local communication network 600 are considered to match. Sends a response 803 to allow login to the second terminal 300. The number of hops is the number of communication devices such as router devices that are routed until the packet sent from the transmission source reaches the transmission destination, and the predetermined number of hops is set appropriately by the network administrator or user. It shall be possible.
Therefore, the CPU 101 functions as the response transmission unit 404.

For example, as shown in FIG. 14, when the first and second local communication networks 500 and 600 are composed of a plurality of communication devices and the predetermined number of hops is set to 3, the response transmission unit 404 receives the received MAC address. Terminal identification information of the communication device through which each packet passes is acquired for the packet including the ID (the unique information 801) and the packet including the user ID and password (the login request 802). Then, the IP addresses (“a1”, “a2”, “A1”) of the third communication devices 501, 502, 711 from the first terminal 200 (portable game device) and the second terminal 300 (video game) The IP addresses (“b1”, “b2”, “B1”) of the third to third communication devices 601, 602, 721 are compared.

A communication device through which the login request 802 arrives at the server device 400, and the communication device within the predetermined hop number. It is determined whether or not any of the devices matches (step S406). If the response transmission unit 404 determines that any of the communication devices within the predetermined number of hops match (step S406; Yes), the response transmission unit 404 transmits a response 803 permitting login to the second terminal 300 (step S307). On the other hand, when the response transmission unit 404 determines that none of the communication devices within the predetermined number of hops match (step S406; No), the response transmission unit 404 notifies the second terminal 300 that the login authentication has not succeeded ( Step S310).

  For example, if the predetermined number of hops is 3, the response transmission unit 404 is a communication device through which a packet including a MAC address passes, and any one of the IP addresses of the third communication device from the portable game device, When the packet including the user ID and the password passes through and the IP address of the communication device from the video game device to the third one matches, that is, as shown in FIG.

Passes through the communication devices 722 to 72 m and reaches the server device 400.

  Next, information included in packets transmitted from the first terminal 200 and the second terminal 300 to the server device 400 will be described. In the present embodiment, it is assumed that a protocol in which the information on the transmission source terminal and the information on the transmission destination terminal are added to the header part of the packet transmitted from the first terminal 200 and the second terminal 300 is used. In the present embodiment, a protocol in which a pair (terminal identification information) of an IP address and a port number of a communication device that has passed is used for a packet that has passed through the communication devices 712 to 71n and 722 to 72m is used. To do.

In the present embodiment, the first terminal 200 and the second terminal 300 have the same functional configuration as that of the first embodiment. Therefore, detailed description of the first terminal 200 and the second terminal 300 is omitted.

(Outline configuration of server device)
The server device 400 includes a storage unit 401, an information reception unit 402, a request reception unit 403, and a response transmission unit 404. The information receiving unit 402 and the request receiving unit 403 have the same functions as those in the first embodiment. Hereinafter, the storage unit 401 and the response transmission unit 404 having functions different from those of the first embodiment will be described.

  The storage unit 401 stores a pair of unique information 801 (such as a MAC address) for identifying a terminal and user identification information 802a (such as a user ID and a password) for identifying a user. For example, the storage unit 401 stores an authentication table 401a as illustrated in FIG.

The storage unit 401 stores a pair of communication device identification information for identifying a communication device and administrator identification information for identifying an administrator who manages the communication device. The administrator identification information is used for identifying a company or a trader who owns a global IP address. For example, the administrator identification information is the company name of the Internet service provider. The communication device identification information identifies a communication device managed by an Internet service provider or the like, and is, for example, a global IP address assigned to the communication device. Usually, one Internet service provider manages a plurality of IP addresses and provides an Internet connection service. Therefore, one administrator identification information is associated with a plurality of IP addresses. When expressing a plurality of IP addresses, a pattern using “*” or the like can be used. In the present embodiment, the communication device identification information is an IP address assigned to the communication devices 712 to 71n and 722 to 72m. For example, the storage unit 401 stores an administrator identification table 401b as illustrated in FIGS. The administrator identification table 401b indicates the manager ID 401b1 for identifying the managers of the communication devices 712 to 71n and 722 to 72m, and the IP addresses of the communication devices 712 to 71n and 722 to 72m managed by the manager. The IP address range 401b2 is registered in association with each other.

That is, in the present embodiment, the first local communication network 500 and the second local communication network 600 that are communication devices within a predetermined number of hops and configured by communication devices managed by the same administrator are regarded as matching. .
Therefore, the CPU 101 functions as the response transmission unit 404.

  For example, as shown in FIG. 17, when the unique information 801 and the login request 802 transmitted from the first terminal 200 and the second terminal 300 reach the server device 400 via a plurality of communication devices, a predetermined hop Assuming that the number is set to 3, the response transmission unit 404 passes each packet for a packet including the received MAC address (unique information 801) and a packet including the user ID and password (login request 802). The communication device identification information of the communication device is acquired. Then, the IP addresses (“A2”, “A3”, “A4”) of the third communication device 712, 713, 714 from the first terminal 200 (portable game device) and the second terminal 300 (video game) Device) to the third communication device 722, 723, 724 ("B2", "B3", "B4") of the communication device 722, the administrator identification table of FIG. 19 (a) or FIG. 19 (b) Compare with reference to 401b.

  In the administrator identification table 401b of FIG. 19A, the IP addresses of the communication devices managed by the administrator “PP” are “A2 to A4”, and the IP addresses of the communication devices managed by the administrator “QQ”. The IP address of the communication device managed by “B2, B3” and the administrator “RR” is registered as “B4”. That is, it is determined that there is no communication device managed by the same administrator among the communication devices up to the third hop number, and as shown in FIG. 17, the first local communication network 500 and the second local communication network 600 are used. Are considered not to match.

  On the other hand, in the administrator identification table 401b of FIG. 19B, the IP addresses of the communication devices managed by the administrator “PP” are registered as “A2 to A4, B2”. That is, it is determined that there is a communication device managed by the same administrator among the communication devices up to the third hop number through which each packet has passed, and as shown in FIG. And the second local communication network 600 are regarded as matching. Therefore, when the administrator identification table 401b is set as shown in FIG. 19B, if the other conditions (above (A) and (B)) are satisfied, the response transmission unit 404 sets the data portion of the packet. , Including the session ID assigned to the second terminal 300, the terminal identification information “C: Z” of the transmission source server apparatus 400 and the terminal identification information “B of the transmission destination second terminal 300” in the header of the packet. : Y ”is transmitted.

The process (response transmission process) shown in the flowchart of FIG. 20 is performed. In this embodiment, the unique information transmission process (FIG. 11) and the login request transmission process (FIG. 12) are the same as those shown in the first embodiment. Therefore, the description of the unique information transmission process and the response transmission process is omitted.

(Response transmission processing)
When the information processing apparatus 100 that implements the server apparatus 400 is turned on, the CPU 101 starts a response transmission process (FIG. 20). In the flowchart of FIG. 20, steps having the same step numbers as in FIG. 13 perform the same processing as the processing in the flowchart of FIG. Hereinafter, steps for performing processing different from the first embodiment will be described.

Notification is made (step S310).

  For example, if the predetermined number of hops is 3, the response transmission unit 404 is a communication device through which a packet including a MAC address passes, and is associated with the IP addresses of the third communication device from the portable game device. One of the administrator IDs is a communication device through which a packet including a user ID and a password passes, and one of the administrator IDs associated with the IP addresses of the third communication device from the video game device matches. In the case (that is, when the administrator identification table 401b is set as shown in FIG. 19B), the response transmission unit 404 determines that the first local communication network 500 and the second local communication network 600 match. . On the other hand, when the unique information 801 and the login request 802 do not pass through a communication device managed by the same administrator within a predetermined number of hops (that is, the administrator identification table 401b is set as shown in FIG. 19A). The response transmission unit 404 determines that the first local communication network 500 and the second local communication network 600 do not match.
