  The management server 4 is a device for managing the communication system. The management server 4 can communicate with the wireless communication terminal 3. The management server 4 stores setting application software and provides the setting application software to the wireless communication terminal 3. The management server 4 can also collect information indicating the status of the router device 1 and the media adapter device 2 from the wireless communication terminal 3 executing the setting application software.

  FIG. 2 is a block diagram for explaining a detailed configuration of the wireless communication terminal 3.

  The wireless communication terminal 3 includes a connection unit 31, a wireless communication unit 32, a storage unit 11, and a control unit 33.

  The connection unit 31 is an interface for connecting to the media adapter device 2. The wireless communication terminal 3 can connect to the media adapter device 2 via the connection unit 31 and perform data transmission / reception. The connection unit 31 transmits data input from the control unit 33 to the media adapter device 2, and transmits data received from the media adapter device 2 to the control unit 33.

  The wireless communication unit 32 is a communication interface for connecting to the wireless network provider network 8. For example, an antenna (not shown) that transmits and receives wireless signals and a wireless signal that is transmitted and received via the wireless network provider network 8. And a signal processing unit (not shown) that performs various types of signal processing. The wireless communication unit 32 outputs the data input from the control unit 33 to the wireless network provider network 8, and outputs the data input from the wireless network carrier network 8 to the control unit 33.

  The storage unit 11 stores setting application software and setting parameters used by the control unit 33 when the setting application software is being executed.

  The control unit 33 controls the wireless communication terminal 3. The control unit 33 is a control device such as a CPU (Central Processing Unit), for example, and implements various functions by reading a program stored in the storage unit 11 and executing the read program.

  In the present embodiment, the control unit 33 executes setting application software stored in the storage unit 11 and controls the communication system according to the setting application software. Specifically, the control unit 33 relays adapter communication of the router device 1. In addition, the control unit 33 establishes management communication with the router device 1 and the media adapter device 2, and remotely operates the router device 1 and the media adapter device 2 using the management communication. The control unit 33 remotely controls the router device 1 and the media adapter device 2 to change parameters related to adapter communication set in each of the router device 1 and the media adapter device 2.

  For example, the control unit 33 changes the parameters of the media adapter device 2 so that the media adapter device 2 notifies the wireless communication terminal 3 of the state of its own buffer. Further, the control unit 33 changes the parameters of the media adapter device 2 so that the media adapter device 2 notifies the wireless communication terminal 3 of the state of its own interface. In addition, the control unit 33 changes parameters indicating the buffer sizes of the router device 1 and the media adapter device 2, respectively. Further, the control unit 33 changes a parameter indicating a communication speed at which the router device 1 transmits data by adapter communication, or changes a parameter indicating route information used by the router device 1 for adapter communication.

  Further, the control unit 33 can also change parameters related to adapter communication set in each of the router device 1 and the media adapter device 2 based on the management information received from the management server 4. When the management information received from the management server 4 has a data format according to a protocol that cannot be interpreted by the router device 1 and the media adapter device 2, the control unit 33 converts the data format of the management information.

When the router device 1 transmits a request message for establishing management communication to the wireless communication terminal 3 based on the notified communication information and the authentication information, the control unit 33 sends a request message from the router device 1. And authentication information is received, and authentication processing is performed based on the received authentication information.

  FIG. 3 is a diagram for explaining the operation of the communication system according to the first embodiment of the present invention.

  The user connects the wireless communication terminal 3 that has downloaded the setting application software from the management server 4 and the media adapter device 2 via the connector 6, and connects the media adapter device 2 and the router device 1 via the LAN cable 5. Further, the user turns on the power of the media adapter device 2 (step S100).

  The router device 1 transmits a request message for requesting connection to the Internet and a connection parameter used for Internet connection to the media adapter device 2 by PPPoE (Point to Point Protocol over Ethernet) connection (step S101). Upon receiving this request message and connection parameter, the media adapter device 2 confirms this connection parameter and transfers this connection parameter and request message to the wireless communication terminal 3 (step S102). The wireless communication terminal 3 receives the request message and connection parameters from the media adapter device 2, and transfers the request message and connection parameters to the wireless network provider network 8 to request setting for Internet connection (step S103). .

  The server that performs Internet connection processing in the wireless network 8 receives the request message and connection parameters transferred by the wireless communication terminal 3 (step S104). Based on the received connection parameters, the server in the wireless network provider network 8 determines operational parameters to be set in the router device 1 and transfers the operational parameters to the wireless communication terminal 3 (step S105). The operation parameter is a parameter set in the router device 1 in order to control adapter communication. The wireless communication terminal 3 receives an operation parameter from a server in the wireless network provider network 8 and performs a transfer process for transferring the operation parameter to the media adapter device 2 (step S106). Further, the media adapter device 2 receives the signal transferred by the wireless communication terminal 3, and performs a conversion process for converting this signal into an electric signal used in Ethernet (step S107). The router device 1 sets an operation parameter included in the signal transferred from the media adapter device 2 to itself, thereby establishing an Internet connection for connection to the Internet network 9 via the media adapter device 2 and the wireless network operator network 8. This is performed (step S108).

  On the other hand, when the power of the media adapter device 2 is turned on in step S100, the wireless communication terminal 3 transmits communication information to the media adapter device 2 (step S109). When the media adapter device 2 receives the communication information and responds to the request message from the router device 1, the media adapter device 2 adds the communication information received from the wireless communication terminal 3 to the option part of the response message and sends it to the router device 1. Transmit (step S110). As a result, the router device 1 obtains communication information (step S111).

  The router device 1 that has obtained the communication information uses this communication information to transmit an authentication request message for requesting connection authentication processing to the media adapter device 2 by PPPoE and an authentication key to the media adapter device 2 (step S112). . The media adapter device 2 receives the authentication request message and the authentication key from the router device 1, and transmits the received authentication request message and authentication key to the wireless communication terminal 3 (step S113). When receiving the authentication request message and the authentication key, the wireless communication terminal 3 performs an authentication process using the authentication key (step S114).

  On the other hand, the media adapter device 2 assigns an IP address for connecting to the media adapter device 2 to the router device 1 in response to the authentication request message, and notifies the assigned IP address to the router device 1 (step S115). . The router device 1 registers the IP address notified from the media adapter device 2 in the router device 1 itself (step S116).

  Further, the router device 1 transmits, to the media adapter device 2, a notification request message for requesting the wireless communication terminal 3 to notify the setting parameter for the router device 1 to directly connect to the wireless communication terminal 3 based on the communication information. , Make setting registration connection to download setting parameters. At this time, the router device 1 transmits an authentication key and a notification request message to the media adapter device 2 based on the communication information (step S117). The media adapter device 2 converts the communication method for the notification request message and the authentication key, and transfers them to the wireless communication terminal 3 (step S118). The wireless communication terminal 3 performs an authentication process based on the received authentication key, and transmits this notification request message to the management server 4 when the authentication is successful. Then, the wireless communication terminal 3 outputs the setting parameter stored in the storage unit 11 to the media adapter device 2 (step S119). The management server 4 receives the notification request message from the wireless communication terminal 3 (step S120).

  When the router device 1 downloads the setting parameter from the wireless communication terminal 3, the router device 1 establishes a management connection with the wireless communication terminal 3 using the setting parameter. When the management connection is established, the wireless communication terminal 3 changes the parameters set in the media adapter device 2 so that the media adapter device 2 notifies the wireless communication terminal 3 of the buffer state and the interface state. The buffer status and interface status of the media adapter device 2 are monitored. Further, when the management server 4 receives the notification request message from the wireless communication terminal 3 in step S <b> 120, the management server 4 transfers operation parameters for controlling adapter communication to the wireless communication terminal 3. When receiving the operation parameter from the management server 4, the wireless communication terminal 3 changes the parameters set in the router device 1 and the media adapter device 2 based on the received operation parameter. When the data format of the received operation parameter is a data format that cannot be interpreted by the router device 1 or the media adapter device 2, the wireless communication terminal 3 sets the operation parameter in the router device 1 or the media adapter device 2. A translation process is performed to convert the parameters into parameters, and the router device 1 or the media adapter device 2 is remotely operated to change the parameters (steps S121 to S124).

  Further, the management server 4 notifies the wireless communication terminal 3 of the operation parameter when the operation parameter is updated according to the state of the network. The operation parameter to be updated is, for example, route information. When a network disconnection occurs on the route from the router device 1 to the communication destination and a route that cannot be used is generated, the management server 4 outputs new route information (step S125).

  The wireless communication terminal 3 changes the parameter set in the router device 1 or the media adapter device 2 based on the updated operation parameter. If the router device 1 or the media adapter device 2 cannot interpret the operation parameter in the data format as it is, the wireless communication terminal 3 converts the data format of the operation parameter, establishes a telnet session, and converts the operation parameter. Operation parameters are set in the router device 1 or the media adapter device 2 (step S126). In the router device 1, the parameter is changed by the wireless communication terminal 3 through the management connection (step S127).

  FIG. 4 is a diagram for explaining communication established in the communication system of FIG. Through the processes from step S100 to step S127, the router device 1 establishes PPPoE connections 300 and 301 to the media adapter device 2 via the LAN cable 5. In addition, the router device 1 establishes adapter communication connected to the Internet network 9 via the media adapter device 2 and telnet communication 309 and 310 which are management connections with the setting application of the wireless communication terminal. The wireless communication terminal 3 establishes communication between the media adapter device 2 and the management connections 303 and 304.

  FIG. 5 is a diagram for explaining information transmitted and received by the PPPoE connection performed between the router device 1 and the media adapter device 2.

  When a PPPoE connection is made from the router device 1 to the media adapter device 2, the media adapter device 2 adds the Vender-Specific tag 200 as optional information and the additional service name to the information responding from the media adapter device 2 to the router device 1. A tag 201 is added.

  The value of the additional service name tag 201 is a service name for another session for management connection, and the value of the Vender-Specific tag 200 is a key for starting another session.

  FIG. 6 is a diagram for explaining buffer control according to the present embodiment.

  The communication speed between the router device 1 and the media adapter device 2 and the communication speed between the media adapter device 2 and the Internet network 9 are usually different. When the communication speed between the router device 1 and the media adapter device 2 is slower than the communication speed between the media adapter device 2 and the Internet network 9, the router device 1 and the media adapter device 2 respectively transmit data to be transmitted. The data can be temporarily stored in the buffer and stored, and data can be sequentially transmitted in accordance with the communication speed between the media adapter device 2 and the Internet network 9.

  However, if data larger than the buffer size stays, the router device 1 and the media adapter device 2 cannot process the data 400 to be transmitted, a part of the data 400 is not transmitted, and a buffer overflow that becomes the untransmitted data 401. The phenomenon called may occur.

  This phenomenon called buffer overflow is likely to occur when, for example, a large delay or congestion occurs between the media adapter device 2 and the Internet network 9. Once the buffer overflow occurs, unsent data may be retransmitted by the transmission function of TCP (Transmission Control Protocol). In this case, the amount of data output on the communication path increases, so that more data is transferred to the media adapter. The amount of untransmitted data output to the device 2 further increases.

  Buffer overflow can be suppressed by increasing the buffer size or performing buffer control that reduces the communication speed between the router device 1 and the media adapter device 2. The buffer control is preferably performed according to the communication speed between the media adapter device 2 and the Internet network 9 and the buffer status. For this reason, in the present embodiment, the wireless communication terminal 3 performs buffer control according to the communication speed between the media adapter device 2 and the Internet network 9 and the buffer state by the function of the setting application.

  FIG. 7 is a diagram for explaining the buffer control operation of the communication system according to the first embodiment of the present invention.

  When the management connection is established by the processing of step S127 shown in FIG. 3, the router device 1 determines the current buffer status of the media adapter device 2, the line speed of the wireless network 8 and the buffer status. Data for confirming the state of the communication system, such as a threshold for determining whether or not, is transmitted to the wireless communication terminal 3 (step S200).

  On the other hand, the media adapter device 2 periodically checks the buffer status of the media adapter device 2 according to the setting from the wireless communication terminal 3 (step S201).

  Further, the media adapter device 2 notifies the data indicating the confirmed buffer status. The media adapter device 2 determines whether or not data exceeding the threshold value is stored in the buffer using, for example, a threshold value, and if the data exceeding the threshold value is stored, the buffer amount is greater than or equal to a predetermined value. The indicated data is notified to the wireless communication terminal 3. The data notified to the wireless communication terminal 3 may include the current buffer size, the data amount, and the threshold value used for the determination (step S202).

  FIG. 8 and FIG. 9 are diagrams illustrating an example of a data notification format notified from the media adapter device 2 to the wireless communication terminal 3. The media adapter device 2 notifies the wireless communication terminal 3 of data using notification formats 507 and 508 determined in advance by the setting application software.

  The wireless communication terminal 3 acquires the line speed of the wireless network provider network 8 and confirms the current state of the communication system based on the data received from the media adapter device 2 (step S203). Then, the wireless communication terminal 3 determines a setting parameter based on the acquired data and notifies the router device 1 (step S204).

  Upon receiving the data notification from the wireless communication terminal 3, the router device 1 checks the buffer state based on this data (step S205).

  If the router device 1 determines that the buffer is overflowing, the router device 1 performs a shaping process on the interface connected to the media adapter device 2 to reduce the communication speed between the router device 1 and the media adapter device 2 (step S206). ).

  The router device 1 also performs buffer size adjustment processing. The router device 1 increases the size of the buffer provided in the router device and the media adapter device 2 (step S207).

  When the router apparatus 1 reduces the communication speed to a predetermined value in the shaping process in step S206, and increases the buffer size to a predetermined value in the buffer size adjustment process in step S207, the router apparatus 1 again performs the buffer in step S205. Perform status confirmation processing.

  Although not shown here, the router device 1 can further perform path control when the communication speed is reduced to a predetermined limit value and the buffer overflows even if the buffer size is increased. In this case, the wireless communication terminal 3 may acquire route information from the management server 4 and route control may be performed based on this route information.

  As described above, according to the present embodiment, the wireless communication terminal 3 connected to the media adapter device 2 and the wireless network operator network 8 that performs communication system conversion is connected to the media adapter device 2 and the wireless network operator network. 8, the parameters relating to the adapter communication set in each of the router device 1 and the media adapter device 2 that establishes adapter communication to connect to the Internet network 9 that is a predetermined network via the wireless communication unit 32 and the wireless network operator It changes based on communication information with the network 8. Thereby, traffic control of adapter communication is performed by the wireless communication terminal 3. Since the wireless communication terminal 3 is connected to the wireless network provider network 8, the wireless communication terminal 3 can download an application through the network or accept a setting change through the network. For this reason, it becomes possible to easily change the content of traffic control of adapter communication.

  According to the present embodiment, the communication information for the router device 1 to establish communication with the wireless communication terminal 3 is notified from the wireless communication terminal 3 to the router device 1, and the router device 1 is based on this communication information. Communication is established to change the parameters. As a result, the contents of the communication information can be easily changed.

  Further, according to the present embodiment, the wireless communication terminal 3 acquires management information for controlling adapter communication from the management server 4, and based on the acquired management information, the parameters of the router device 1 or the media adapter device 2 To change. Thereby, management information can be changed easily, and it becomes possible to control adapter communication via a network.

  The management information may be route information related to adapter communication. Further, the wireless communication terminal 3 can change the parameters of the router device 1 by converting the data format of the acquired route information according to the routing protocol used by the router device 1. As a result, when a new routing protocol is used on the network, even if the router device 1 cannot execute software for controlling the router device 1 based on this routing protocol, the router device 1 It becomes possible to operate according to a new routing protocol.

  According to the present embodiment, the wireless communication terminal 3 notifies the router device 1 and the media adapter device 2 of information for controlling adapter communication by changing the parameters of the router device 1 and the media adapter device 2. Let Thereby, since control of adapter communication is performed via the radio | wireless communication terminal 3, it becomes possible to change the control content of adapter communication easily.

  The wireless communication terminal 3 may also notify information indicating the status of the router device 1 and the media adapter device 2 buffer as information for controlling adapter communication. The wireless communication terminal 3 can change the size of the buffer based on the notified information. Thereby, the buffer overflow in adapter communication can be suppressed, and the traffic of adapter communication can be appropriately controlled.

  Further, according to the present embodiment, the wireless communication terminal 3 changes the parameters of the media adapter device 2 to notify the wireless communication terminal 3 of the interface state. As a result, it is possible to grasp the status of the interface of the media adapter device 2 via the network. For this reason, even if the media adapter device 2 breaks down, the cause of the failure can be identified without going to the site where the media adapter device 2 is installed.

(Second Embodiment)
In the first embodiment, PPPoE is used for adapter communication in which the router device 1 is connected to the Internet network 9 via the media adapter device 2 and the wireless network operator network 8, but the present invention is not limited to this example. A method other than PPPoE may be used for adapter communication. Hereinafter, a case where DHCP (Dynamic Host Configuration Protocol) is used for adapter communication will be described as a second embodiment.

  FIG. 10 is a diagram for explaining the operation of the communication system according to the second embodiment of the present invention.

  In the present embodiment, the configuration of the communication system and the basic functions of each component are the same as those in the first embodiment, and thus description thereof is omitted here.

  The router device 1 makes a connection 501 with the media adapter device 2 using PPPoE. Then, each process shown in FIG. 3 is performed using this connection 501, and when the operation parameters shown in step S121 are downloaded, the adapter communication for connecting to the Internet is changed to the DHCP client, and the Internet connection 502 is set by DHCP. Do.

  At this time, a secondary IP address is registered, and a request message 503 requesting that the wireless communication terminal 3 be a DHCP client of the secondary network is transmitted to the wireless communication terminal 3.
