Description

Communication device automatic setting method and system

The present invention relates to a communication device automatic setting system, and more particularly to a communication device automatic setting method and system using setting information from a service provider.

In order for a communication device such as a data machine or router installed in a user's home or office to be connected to the Internet, setting information of a network service provider (hereinafter referred to as an ISP) must be set. However, as such setting work has become more and more complicated in recent years, various methods have been proposed to reduce the burden on users in this work.

For example, according to the terminal setting method disclosed in PTL 1, an access service provider (ASP) identifies a subscriber based on a logical or physical location where a subscriber terminal is placed, and then notifies the ISP of the information of the specific subscriber. The ISP sends the authentication information back to the subscriber terminal via the ASP, and then the subscriber terminal uses the authentication information to access the ISP, thereby obtaining the setting information.

Moreover, according to the system disclosed in PTL 2, when the router is turned on, the router automatically accesses the initial server that is initially set to be accessible, when the user server receives the URL from the initial server. Access the user server to get the necessary setup information.

{PTL 2} Unexamined Japanese Patent Application, Publication No. 2004-193988

In general, the user who sets the target, that is, the communication device, cannot be easily identified from each ISP that provides the setting information. In the above PTL 1, the user identification is performed in the access service provider based on the logical or physical location where the subscriber terminal is placed. That is, the subscriber can be identified by the access service provider as the communication carrier. In other words, the communication carrier guarantees the identification of the user.

On the other hand, in PTL 2, an initial server is used to record the IDs of all routers used in the system, and the initial server can identify a router. However, the user of the router could not be identified. Moreover, the premise that the user server provides the setting information is that the router that requests the setting information is the router that has accessed the initial server, but it cannot check whether the two routers are the same router. Therefore, there is an inevitable security problem: a party that is not an authorized user may consciously or unconsciously perform unauthorized logins to the user server on the network, such as counterfeiting or unconscious of such third parties. Counterfeiting is due to a router sending error or an incorrect ID registration. In the above-described system in which the communication carrier does not perform user identification, the security is insufficient when the setting information is automatically set on the communication device, and the unauthorized login by the third party cannot be effectively eliminated.

Accordingly, it is an object of the present invention to provide a method and system for automatically setting a communication device that can enhance user identification by causing a service provider other than the communication carrier to enhance user identification.

The system according to the present invention is an automatic setting system for a communication device on a network, and a plurality of servers and communication devices are connected to the network. The system is characterized by: a closed network establishing device, setting a target communication device and providing Setting the information service provider to establish a closed network in response to the initial access from the set target communication device; and automatically setting an automatic setting between the set target communication device and the service providing server via the closed network The device performs an automatic setting procedure.

The method according to the present invention is a method for automatically setting setting information to a communication device on a network, and a plurality of servers and communication devices are connected to the network. The method is characterized in that the method comprises the following steps: receiving a communication from a setting target After the initial access of the device, a closed network is established between the set target communication device and the service providing server providing the setting information by a closed network establishing device; and the set target communication device is inserted through the closed network The service provides an automatic setting device between the servers to execute the automatic setting procedure.

According to the present invention, user identification can also be performed by a communication carrier other than the service provider to enhance security.

In accordance with an embodiment of the present invention, an automatic setting system is interposed between a set target communication device and a service provider to form a closed network and to execute an automatic setting procedure within the closed network. The automatic setting system interposed between the communication device and the service provider undertakes, for example, checking whether the communication device is a communication device being set and information retaining a location on the network to provide setting information, thereby facilitating use of the service provider. Identify and more effectively avoid unauthorized login by third parties. Further, by assigning the program ID to manage the setting program for each communication device, the service provider can easily check whether or not the setting target communication device is being set, so that security can be improved at the time of automatic setting. The illustrative embodiments and examples of the invention will be described in detail hereinafter.

1. Illustrative embodiment 1.1) System

In the network shown in FIG. 1, an exemplary embodiment of the present invention is applied to an automatic setting system 10, and a server of a plurality of service providers ISP1 to ISPn is connected to an IP network 11, such as the Internet. Here, it is assumed that the automatic setting system 10 is a server system including an automatic setting server 10a, a program management unit 10b, and a DNS (Domain Name System) server 10c, and each service provider ISP includes an ISP web server 20a. With ISP-ZC server 20b.

The communication device 12 to be set stores the initial access information and the ID information for identifying the communication device 12 in advance. The initial access information includes the URL (Uniform Resource Locator) of the automatic setting server 10a of the automatic setting system 10 and the domain of restricting the access destination from the communication device 12 to only the ISP web server 20a. The DNS server 10c is used in advance to record the domain of the ISP web server 20a of the service providers ISP1 to ISPn. Therefore, when the communication device 12 performs the initial access, a closed network 30 is established between the communication device 12 and the service provider that provides the necessary setting information, and the communication device 12 and the service provider are in the process of setting the program. Communication takes place via the closed network 30. In an open IP network, The automatic setting server 10a can only receive communications from the communication device 12 by forming a closed network.

Further, access from the communication device 12 is limited to accessing the automatic setting server 10a and accessing the ISP web server 20a. As will be described later, accessing the ISP web server 20a is limited to the case where the target communication device 12 is set to be in progress and other accesses from the IP network may be rejected. Both the auto-set server 10a and the ISP web server 20a can avoid unauthorized logins from open IP networks.

The ID information on the communication device 12 is sufficient as long as it is information such as a MAC address or serial number that enables the communication device 12 to be recognized. As will be described below, the automatic setting server 10a can establish a closed network 30 between the communication device 12 and the service provider by allowing the user to connect the communication device 12 only to the IP network 11 and perform initial access. User identification and setting of information are automatically performed via the closed network 30.

It should be noted that the communication device 12 is provided with a program control processor such as a CPU (Central Processing Unit) as a control portion for controlling the operation of the communication device, and the above-described function as the communication device can be performed by executing the program on the program control processor. This is achieved by a program in the memory inside the communication device. Further, the automatic setting server 10a is also provided with a program control processor such as a CPU (Central Processing Unit) as a control unit for controlling the operation as a server, and the above-described function as an automatic setting server can be handled by the program control. The program stored in the memory inside the automatic setting server is executed on the device.

1.2) System operation

Referring to FIG. 2, when the communication device 12 in the initial state is connected to the IP network 11, the automatic setting server 10a is accessed by using the initial access information, and the ID information on the communication device 12 is encrypted and transmitted (job S1). Upon receiving the initial access from the communication device 12, the automatic setting server 10a starts the automatic setting program and issues an ID number pID (program ID) to the program. The automatic setting server 10a registers the ID information on the communication device 12 with the program management unit 10b and its automatic setting process. Sequence ID (job S2). Preferably, a valid period of time is set for the program ID registered to the program management unit 10b. Further, the automatic setting server 10a notifies the communication device 12 of the program ID and the URL for accessing the service provider ISP (job S3). It should be noted that the domain of each service provider ISP is preferably registered in advance using the DNS server 10c, and the DNS server 10c provides name resolution when the communication device 12 accesses its notified URL.

Next, the communication device 12 accesses the service provider ISP by using the notified URL by the automatic setting server 10a, and sends a setting request including the program ID (job S4). Upon receiving the setting request from the communication device 12, the service provider ISP transmits a request to the program management unit 10b of the automatic setting system 10, and asks the program management unit 10b to check whether or not the setting using the program ID is in progress (job S5). .

The program management unit 10b determines whether or not the program ID requested to be checked has been validly registered. If the program ID has not expired and the setting is being made, the confirmation is sent back to the service provider ISP (job S6).

The service provider ISP that has received the confirmation starts the authentication procedure of the communication device 12 by the automatic setting server 10a (job S7). However, the automatic setting server 10a does not involve the authentication procedure and cannot see the exchange of authentication information between the user and the service provider ISP.

When the user of the communication device 12 is successfully authenticated, the service provider ISP causes the program management unit 10b of the automatic setting system 10 to retain the URL of the ISP-ZC server that performs setting of the setting information and notifies the communication by the automatic setting server 10a. The device 12 is configured to start acquiring the setting initialization URL of the setting information (job S9).

The communication device 12 that has received the setting initialization URL accesses the automatic setting server 10a and starts acquiring the setting information (job S10). Upon receiving the access from the communication device 12 to start acquiring the setting information, the automatic setting server 10a acquires the URL of the ISP-ZC server reserved for the communication device 12 from the program management unit 10b (job S11), and stores The ZC server of the service provider ISP is fetched and then the setting information for the communication device 12 is acquired (job S12).

After the setting information is acquired in this manner, the automatic setting server 10a transmits the setting information to the communication device 12 in response to the above-described access job S10 (job S13). The communication device 12 uses the setting information downloaded in this way to complete the necessary settings.

1.3) Operation of the communication device

Referring to FIG. 3, when the communication device 12 is activated in the initial stage, the user setting browser is activated, asking the user to select manual setting or automatic setting (job 301). When the user selects the automatic setting (job 302), the automatic setting server 10a is connected based on the initial access information (job 303), and the program ID and the destination ISP are acquired by accessing the automatic setting server 10a. The URL of the web server 20a (job 304). Next, the communication device 12 accesses the ISP web server 20a of the service provider ISP using the acquired ISP-URL (job 305), and the ISP web server 20a starts the authentication process (job 306).

When the ISP web server 20a completes the authentication (job 306: OK), the automatic setting phase is started and the setting initialization URL is received from the ISP web server 20a (job 307). The communication device 12 that has received the setting initialization URL starts to access the automatic setting server 10a, whereby the automatic setting server 10a acquires the setting information from the service provider ISP in the above manner and transmits it to the communication device 12. That is, the communication device 12 downloads necessary setting information (job 308) from the automatic setting server 10a and completes the setting (job 309). When the setting is completed in this manner, the job status is started (job 310). It should be noted that when the authentication fails (job 306: NG), the communication device 12 receives the disallowed setting (job 311), immediately terminates abnormally, and the closed network 30 is disconnected (job 312).

1.4) Automatically set the system's operation

Referring to FIG. 4, when the initial access and ID information is received from the communication device 12 (job 401), the automatic setting server 10a starts the user identification phase, and first generates the ID information, the access time, and the like on the communication device 12. A unique program ID (job 402). Next, the automatic setting server 10a establishes the association between the program ID and the ID information on the communication device 12 and registers it with the program management unit 10b, and simultaneously sets the program. The ID and the ISP-URL of the access destination are transmitted to the communication device 12 (job 403), and then a timer for checking the effective time of the program ID (job 404) is started.

When receiving a request from the service provider ISP to check whether the setting program (program ID) of the communication device 12 is valid, the automatic setting server 10a refers to the registration data in the program management unit 10b, thereby sending the confirmation back to the service provider. ISP (job 405). Further, when receiving the URL from the service provider ISP requesting registration of the setting information position of the communication device 12, the automatic setting server 10a registers the URL associated with the communication device 12 with the program management unit 10b (job 406). . Upon receiving the request request setting information from the communication device 12 (job 407), the automatic setting server 10a accesses the URL registered to the program management unit 10b and acquires the setting information from the service provider ISP (job 408). The automatic setting server 10a transmits the acquired setting information to the communication device 12 (job 409), and receives a notification of setting completion from the communication device 12 when the setting is completed at the communication device 12 (job 410).

The above operations 405 to 410 need to be completed before the timer expires (job 411). If a timeout occurs (job 411: YES) or a notification that the setting is completed is received, the program management unit 10b deletes the information related to the communication device 12 and disconnects the closed network (job 412).

1.5) Effect

As described above, the automatic setting system according to an exemplary embodiment of the present invention is inserted between the communication device 12 requesting automatic setting and the service provider ISP to form a closed network 30 and both operate via the closed network 30, such as checking communication. Whether the device 12 is a communication device being set, retaining URL information for providing setting information, and the like. Therefore, the user identification by the service provider is promoted and the illegal login of the third party is more effectively avoided. Further, by managing the presence of the program management unit 10b of the setting program for the communication device 12 by assigning the program ID, the service provider ISP can easily check whether or not the setting destination communication device 12 is actually being set, and can improve the security at the time of automatic setting. Sex.

2. Examples

An automatic setting system according to an example of the present invention will be described in detail later. It should be noted that in the present example, a network connection device such as a router will be considered as an example of the communication device 12 in FIG. 1 and it is assumed that the terminal is connected to the network connection device.

2.1) Configuration

Referring to FIG. 5, an automatic setting system 10 according to an embodiment of the present invention is connected to a plurality of service provider ISPs, network connection devices 12, and a mail server 14 via a network 11, and the terminal 13 is connected to the network such as a personal computer. Road connection device 12. Further, in the present example, it is assumed that the network connection device 12 is delivered to the user's home, and the mail server 14 that has recorded the delivery information of the network connection device 12 and the automatic setting system 10 communicate with each other.

The automatic setting system 10 includes: an automatic setting ZC (zero setting) server 101 on the network connecting device 12, an portal web server 102, a program management database 103, a mailing contact database 104, a recording server 105, and DNS server 106. The ZC server 101 uses the program management database 103, the mailing contact database 104, the recording server 105, and the DNS server 106 to control the automatic setting program between the service provider ISP and the network connection device 12.

The network connection device 12 includes a control unit 121 that controls all jobs on the network connection device 12, a memory 120 that stores initial access information, a WAN-side interface that is connected to the network 11, and a terminal 13 that is connected to the terminal 13. LAN-side interface and communication control unit (not shown) of such interfaces.

The service provider ISP includes an ISP web server 201 and an ISP-ZC server 202 that performs automatic setting of setting information.

2.2) First job instance <user identification stage>

Referring to FIG. 6, the initial access information of the network connection device 12 includes: the domain "zeroconfig.xxx.jp" used when initially accessing the ZC server 101 of the automatic setting system 10 and the domain used in requesting settings. "setup.xxx.jp". Network connection device 12 The terminal and the connected terminal 13 can only access the domain and subdomain of the initial access information. Further, the domain of the service provider ISP is registered with the DNS server 106 of the automatic setting system 10 in advance. Further, it is assumed that the MAC address of the network connection device 12, the URL of the access destination ("isp.setup.xxx.jp"), and the mailing information are stored in advance in the mailing contact database from the mail server 14. In 104, other similar information is also sent to the ISP web server 201 of the service provider ISP. It should be noted that the mailing contact database 104 can be housed in an ISP web server or can be housed in another server that is commonly used by the mail server and the ISP web server.

In Fig. 6, it is assumed that the user has selected the automatic setting from the setting screen of the network connection device 12 by the terminal 13 connected to the network connection device 12 (job S21). When the automatic setting is selected, the control unit 121 of the network connection device 12 reads the information "zeroconfig.xxx.jp" at the time of initial access from the initial access information memory 120, and encrypts the MAC address according to the https protocol (its The ID information of the device 12 is connected to the network and transmitted to the ZC server 101 (job S22).

After receiving the MAC address from the network connection device 12 via the initial access, the ZC server 101 issues a program ID based on the MAC address and time, and then starts a timer of the valid time at the time of registration (job S23). The MAC address and the program ID are registered to the program management database 103 (job S24). Next, the ZC server 101 encrypts the program ID and the URL (isp.setup.xxx.jp) for accessing the service provider ISP and transmits it to the network connection device 12 (job S25). Next, the setting guidance is started, and if necessary, the version upgrade is performed (job S26).

When the user operates the terminal 13 and selects to execute the program (job S27), the terminal 13 encrypts the program ID and transmits it to the URL (isp.setup.xxx.jp) acquired from the ZC server 101 (job S28). More specifically, the access is made to the ZC server 101 based on https://isp.setup.xxx.jp but is resolved by the DNS server 106 to be directly transferred to the ISP web server 201 of the service provider ISP .

Upon receiving the access to the setting request, the ISP web server 201 of the service provider ISP sends a request to the program management database 103 of the automatic setting system 10 to check whether the program ID of the program is being set (job S29). . Cheng The order management database 103 determines whether the program ID requested to be checked has been effectively registered (job S30), and if the program ID has not expired and the set program is being executed, the confirmation is sent back to the ISP web server 201 (job S31) ). When the automatic setting system 10 confirms that the program ID is valid in this manner, the service provider ISP can recognize that the user accessing the terminal 13 is the user of the network connection device 12.

Next, the ISP web server 201 that has received the confirmation requests the terminal 13 for authentication by the ZC server 101 (job S32). The ZC server 101 will only refer to the DNS server 106 to relay the authentication procedure but cannot see the exchange of information between the user and the service provider ISP.

The user operates the terminal 13 and inputs the authentication data, and then the authentication data is encrypted and transmitted by the ZC server 101 to the ISP web server 201 (job S33).

<Automatic setting stage>

Referring to FIG. 7, when the user of the network connection device 12 is successfully authenticated (job S34), the ISP web server 201 requests the program management database 103 to retain the URL of the ISP-ZC server 202 (job S35). When the retention of this URL is completed (job S37), the ISP web server 201 transmits the setting initialization URL (xxx.yy/end) to the terminal 13 in the case where the authentication is successful (job S38). Incidentally, if the authentication is NG (failure), the URL (xxx.yy/retry) that is not allowed to be set is transmitted to the terminal 13.

Depending on the result of the authentication, the user selects a program: a setting initialization URL displayed on the terminal 13 or a URL that is not allowed to be set (job S39). When the setting initialization URL is selected, the network connection device 12 recognizes that it is the trigger for starting the setting. When a URL that does not allow setting is selected, the network connection device 12 terminates the setting. When the start setting is selected by the setting initialization URL (job S40), the control unit 121 of the network connection device 12 encrypts the program ID and transmits it to the ZC server 101 (job S41), after receiving the access, The ZC server 101 starts the automatic setting control. First, the ZC server 101 checks with the program management database 103 whether or not the URL corresponding to the program ID exists (job S43). If such a URL has already been registered, the URL is acquired (job S44). After that, the ZC server 101 will set the funds. The request is sent to the ZC server 202 at this URL (job S45), and after receiving the encrypted setting information (response to the request) (job S46), it is transmitted to the network connection device 12 (job S47).

The control unit 121 of the network connection device 12 that has received the setting information performs setting (operation S48), and transmits a recording notification to the ZC server 101 when the setting is completed (job S49). Upon receiving the record notification, the ZC server 101 deletes the program ID stored in the program management database 103 and the information related to the network connection device 12 (job S51). Further, the ZC server 101 sends a confirmation of the recording notification back to the network connection device 12 (operation S52), and the network connection device 12 transmits a notification of completion of setting on the network connection device 12 to the terminal 13 (operation S53).

2.3) Second job instance

If the user purchases the network connection device 12 from, for example, a large shopping mall, the mailing will not be made. In this case, the step of the user operating the terminal 13 to select the ISP is added to the procedure of FIG.

Referring to Figure 8, job S27a is a new program. Since the other programs are substantially the same as those in FIG. 6, the same reference numerals and signs are used, and the description thereof will be omitted herein. However, in the job S25, the program ID from the ZC server 101 and the URL (portal.setup.xxx.jp) of the portal server are transmitted to the network connection device 12.

When the user operates the terminal 13 to make a selection for the program (job S27), the terminal 13 encrypts the program ID and transmits it to the portal web server 102 at the URL (portal.setup.xxx.jp) (job S27). -1). The portal web server 102 transmits the program ID to the program management database 103 to check whether the program is in the setting (job S27-2). If the program is in the setting, the user is allowed to select the plurality of ISPs configured in advance. One of them. Thereby, the ISP-URL of the ISP is selected, and the program ID is transmitted to the terminal 13 (job S27-4). Work S28 and other program steps have been previously described.
