  A user who browses the WEB site on the Internet needs to specify the URL of the target site on the terminal. At this time, when the user accesses the target site, the user accesses the target site by accessing another target site once, and in accordance with the action at the target site, In some cases, benefits provided by the operating company can be obtained. In such a case, the user first specifies the URL and IP address of the transit site, accesses the transit site, and then selects the target site on the transit site, thereby indicating that the user has passed the transit site. In some cases, a technique of accessing a target site using an IP address is used. In this case, when the user designates the URL or IP address of the target site, the URL or IP address of the target site on the router is converted into a URL or IP address indicating that the route is passed. If possible, it is possible to save the user from having to access the transit site. However, in the conventional router device, a technology for converting the URL or IP address of the access destination site only by converting the private IP address to the global IP address. There was no discussion about it.

A URL conversion apparatus according to the present invention includes a first network connection interface for connecting to a first network to which an access source terminal that accesses a website is connected, and a second network that is an access destination of the access source terminal Benefits provided by the transit site operator by accessing from the access source terminal via the transit network via the second network connection interface for connecting to the network and the first network connection interface when there is access to a website that can be acquired, recorded on the storage medium, via different through site from the access source terminal and URL of the website access is assumed, and the URL URL to identify that you have accessed the website after URL conversion information associating the to conversion URL or the IP address of the Web site to which access is assumed from the access source terminal, identifying that it has access to the web site from via different through site and its IP address, Referring to IP address conversion information associated with a conversion IP address indicating an IP address to be used, an access destination conversion that converts an access destination URL or access destination IP address of a website into a conversion URL or a conversion IP address Means.
A URL conversion program according to the present invention includes a first network connection interface for connecting to a first network to which an access source terminal that accesses a website is connected, and a second network that is an access destination of the access source terminal The access destination conversion device having the second network connection interface for connecting to the network is accessed via the first network connection interface from the access source terminal via the transit site. The URL of the website that is expected to be accessed from the access source terminal recorded in the storage medium when the website that can obtain the benefits provided by the site operating company is accessed , and the URL access to the web site from via the different via site and Via different through site is the IP address of the Web site to which access is assumed from the URL conversion information associating the conversion URL indicating a URL for identifying or access source terminal, it was, and its IP address Referring to the IP address conversion information that associates the conversion IP address indicating the IP address for identifying that the website is accessed from the website, the website access destination URL or the access destination IP address is converted to the conversion URL or conversion. This is a program for executing an access destination conversion procedure for converting to a private IP address.

  According to the present invention, URL conversion information that associates a URL of a website that is expected to be accessed from the access source terminal with a conversion URL that is different from the URL, or a website that is assumed to be accessed from the access source terminal. An IP address conversion information in which an IP address and an IP address for conversion different from the IP address are recorded is recorded, and the URL recorded in the storage medium when the access source terminal accesses the website Since the access destination URL or the access destination IP address is converted into the conversion URL or the conversion IP address with reference to the conversion information or the IP address conversion information, the user of the access source terminal can change the access destination URL or the IP address. Simply specify the web site using the conversion URL and conversion IP address. It is possible to access to.

FIG. It is the 1st figure showing a specific example of conversion information typically. FIG. 6 is a flowchart showing the flow of URL conversion processing executed by a router 200. It is the 2nd figure which showed the example of conversion information typically.

  FIG. 1 is a block diagram illustrating a configuration of an embodiment of an access destination conversion system 10 according to the present embodiment. In the access destination conversion system 10, a LAN terminal 100 as an access source terminal and a router 200 as a network device are connected via a wired network or a wireless network. The intra-LAN terminal 100 connected to the local area network can be connected to a wide area network such as the Internet via the router 200. The intra-LAN terminal 100 is a terminal connected to a local area network. For example, a terminal having a communication function such as a personal computer, a server, a smartphone, or a tablet is assumed. Although FIG. 1 shows an example in which the number of intra-LAN terminals 100 connected to the router 200 is one, the number is not limited.

  FIG. 2 is a block diagram showing a configuration of an embodiment of the router 200 in the present embodiment. The router 200 includes a WAN interface 201, a LAN interface 202, a control device 203, and a storage medium 204.

  The WAN interface 201 is an interface for connecting to a wide area network via a LAN cable or the like, and includes, for example, a WAN port and its peripheral circuits.

  The LAN interface 202 is an interface for connecting to a local area network. As a connection method to the local area network, one or both of a wired connection via a wired cable such as a LAN cable and a wireless connection via a wireless LAN are assumed. The LAN interface 202 is composed of a LAN port for wired connection and its peripheral circuit for performing wired connection, and is composed of a wireless LAN module for wireless connection and its peripheral circuit for performing wireless connection. .

  The control device 203 includes a CPU, a memory, and other peripheral circuits, and controls the entire router 200. In addition, the memory which comprises the control apparatus 203 is volatile memory, such as SDRAM, for example. This memory is used as a work memory for the CPU to expand the program when the program is executed and a buffer memory for temporarily recording data.

  The storage medium 204 is a storage medium for recording various data stored in the router 200, program data to be executed by the control device 203, and the like. For example, a nonvolatile storage medium such as a flash memory is used. . Firmware data for operating the router 200 and program data for executing processing to be described later are recorded in the storage medium 204. The firmware and program data recorded in the storage medium 204 may be updated by obtaining the latest data from a server on the Internet connected via the WAN interface. In the present embodiment, conversion information data for URL conversion used in processing to be described later is also recorded in the storage medium 204.

  In the router 200 according to the present embodiment, a URL of a website that is assumed to be accessed from the LAN terminal 100 connected to the local area network, and a conversion URL different from the access destination URL are stored in the storage medium 204. URL conversion information associated with the URL is recorded, and the control device 203 is recorded in the storage medium 204 when the LAN terminal 100 accesses the website via the LAN interface 202. With reference to the conversion information, the access destination URL is converted into a conversion URL.

  As the case where the access destination URL is converted into the conversion URL, the following cases are assumed. A user who browses the WEB site on the Internet needs to specify the URL of the target site on the terminal. At this time, when the user accesses the target site, the user accesses the target site by accessing another target site once, and in accordance with the action at the target site, In some cases, benefits provided by the operating company can be obtained.

  As a specific example, when a user who owns a credit card makes a credit card payment at a shopping site on the Internet, a point corresponding to the payment amount may be acquired. At this time, when a user accesses a transit site operated by a credit card company, selects a target shopping site on the transit site, and accesses the shopping site, the user can obtain a mechanism capable of acquiring more points than usual. There are credit card companies and shopping sites.

  In such a case, in order to acquire more points than usual as an electronic privilege, the user first specifies the URL of the transit site and accesses the transit site, and then selects a target site on the transit site. May be taken. In this case, the site selected by the user on the transit site is pasted with a URL of the conversion URL in which a character string indicating that the transit site has been added to the URL for accessing the target site. Yes. As a result, the user can access the target site using the conversion URL, and the access destination site identifies that the user has accessed via the transit site, and provides a privilege to the user. Can be granted.

  In this case, when the access destination URL of the site intended by the user is associated with the conversion URL for acquiring a privilege corresponding to the user's operation on the router, and the user designates the access destination URL In addition, if the access destination URL can be converted to the conversion URL on the router, the user can automatically specify the via-site necessary for acquiring the privilege simply by specifying the URL of the target site. Since the URL is converted to a URL indicating that the user has passed, it is possible to save the user from having to access the relay site.

  In the following, it is assumed that the user accesses the shopping site via a transit site operated by a credit card company, and even if the user does not access the transit site, the URL for conversion is automatically generated on the router 200. Details of the processing will be described with respect to an example in the case of conversion to. In this case, the access destination URL is the shipping site URL, and the conversion URL is the URL used when accessing the shopping site via the transit site, for example, the shipping site URL via the transit site. This is a URL to which a character string indicating this is added.

  In the present embodiment, the storage medium 204 of the router 200 stores conversion information in which the access destination URL 3a and the conversion URL 3b are associated with each other as shown in FIG. For example, the user who has purchased the router 200 can access the management screen of the router 200 and arbitrarily register the conversion information from a registration screen prepared on the management screen. In this case, the control device 203 accepts registration of conversion information from the intra-LAN terminal 100 and records the conversion information in the storage medium 204.

  In the example of FIG. 3, a conversion URL “http://www.aa.co.jp/keiyu1” is associated with the access URL “http://www.aa.co.jp”. This indicates “http://www.aa.co.jp” indicating that the access to “http://www.aa.co.jp” from the terminal 100 in the LAN has been made via the transit site “keiyu1”. / Keiyu1 ".

  A conversion URL “http://www.bb.co.jp/keiyu1” is associated with the access URL “http://www.bb.co.jp”. This indicates “http://www.bb.co.jp” indicating that the access to “http://www.bb.co.jp” from the terminal 100 in the LAN has passed through the transit site “keiyu1”. / Keiyu1 ".

  A conversion URL “http://www.cc.co.jp/keiyu1” is associated with the access URL “http://www.cc.co.jp”. This indicates “http://www.cc.co.jp” indicating that the access to “http://www.cc.co.jp” from the terminal 100 in the LAN has been made via the transit site “keiyu1”. / Keiyu1 ".

  A conversion URL “http://www.dd.co.jp/keiyu2” is associated with the access URL “http://www.dd.co.jp”. This indicates “http://www.dd.co.jp” indicating that the access to “http://www.dd.co.jp” from the terminal 100 in the LAN is made via the transit site “keiyu2”. / Keiyu2 ”.

  The access URL “http://www.ee.co.jp” is associated with the conversion URL “http://www.ee.co.jp/keiyu3”. This indicates “http://www.ee.co.jp” indicating that the access to “http://www.ee.co.jp” from the intra-LAN terminal 100 is made via the transit site “keiyu3”. / Keiyu3 ”.

  Note that the conversion information setting method shown in FIG. 3 is an example, and the present invention is not limited to this. In addition, in each conversion URL, a via site identified by a transit site identification character string such as “keiyu1”, “keiyu2”, and “keiyu3” in a format in which “/ via site identification character string” follows the access destination URL. However, the method of identifying the transit site in the conversion URL is not limited to this.

  In a state where at least one piece of conversion information is recorded in the storage medium 204 as described above, the control device 203 performs communication when the access destination URL is specified from the LAN terminal 100 via the LAN interface 202. Performs the following processing.

  The control device 203 determines whether there is conversion information in which the access destination URL 3 a matches the access destination URL specified by the terminal 100 in the LAN, among the conversion information recorded in the storage medium 204. As a result, when it is determined that there is conversion information in which the access destination URL 3a matches the access destination URL specified by the LAN terminal 100, the control device 203 determines the access destination URL specified by the LAN terminal 100. Is converted to a conversion URL with reference to the conversion information, and the LAN terminal 100 is made to access the Internet via the WAN interface 201. For example, when the access destination URL is “http://www.ee.co.jp”, the control device 203, based on the conversion information shown in FIG. 3, “http://www.ee. co.jp/keiyu3 ".

  On the other hand, the control device 203 determines that the conversion information recorded in the storage medium 204 does not include conversion information in which the access destination URL 3a matches the access destination URL specified by the LAN terminal 100. In this case, the LAN terminal 100 is made to access the Internet via the WAN interface 201 as it is.

  As a result, when the access destination URL designated by the LAN terminal 100 matches the access destination URL 3a of the conversion information, it is automatically converted into a conversion URL, and the LAN terminal 100 is used using the converted URL. Can access the Internet. On the other hand, when the access destination URL specified by the LAN terminal 100 does not match the access URL 3a of the conversion information, the LAN terminal 100 is accessed to the Internet using the URL specified by the LAN terminal 100 as it is. Can be made.

  FIG. 4 is a flowchart showing the flow of URL conversion processing executed by the router 200. The process shown in FIG. 4 is executed by the control device 203 as a program to be started when there is a communication specifying an access destination URL from the LAN terminal 100 via the LAN interface 202. In FIG. 4, it is assumed that the conversion information described above is recorded in the storage medium 204 in advance.

  In step S10, the control device 203 refers to the conversion information recorded in the storage medium 204, and the conversion information in which the access destination URL 3a matches the access destination URL designated by the LAN terminal 100 is included in the conversion information. It is determined whether or not exists. If a negative determination is made in step S10, the process ends. On the other hand, if a positive determination is made in step S10, the process proceeds to step S20.

  In step S20, the control device 203 converts the access destination URL specified by the LAN terminal 100 into a conversion URL associated with the access destination URL in the conversion information. Thereafter, the process ends.

According to the present embodiment described above, the following operational effects can be obtained.
(1) In the router 200, the conversion information in which the access destination URL of the website that is assumed to be accessed from the LAN terminal 100 and the conversion URL different from the URL is recorded in the storage medium 204, and the control is performed. When the device 203 accesses the website from the LAN terminal 100 via the LAN interface 202, the device 203 refers to the conversion information recorded in the storage medium 204 and converts the access destination URL into a conversion URL. I tried to do it. As a result, even when the user needs to specify a URL that includes the transit site, the user can access the website by simply specifying the access destination URL by the URL automatically converted to the conversion URL on the router 200. can do.

(2) The control device 203 accepts registration of conversion information from the LAN terminal 100 and records the conversion information in the storage medium 204. Thus, the user of the LAN terminal 100 can arbitrarily register the conversion information in which the access destination URL of the site accessed by the user is associated with the conversion URL for the access destination URL in the router 200.

-Modification-
Note that the router 200 of the above-described embodiment can be modified as follows.
(1) In the above-described embodiment, the example in which the control device 203 accepts registration of conversion information from the intra-LAN terminal 100 and records the conversion information in the storage medium 204 has been described. In this case, the transit site through which credit card points are obtained generally differs depending on the credit card company. Therefore, when receiving the registration of the conversion URL to be included in the conversion information from the LAN terminal 100, the control device 203 displays the name of the credit card company or credit card operating the transit site on the screen of the LAN terminal 100. And a conversion URL corresponding to the credit card company name or credit card name selected by the user may be automatically set. Accordingly, the user can save time and effort for inputting the conversion URL because the conversion URL is automatically set only by selecting the credit card owned by the user.

(2) In the above-described embodiment, an example has been described in which the control device 203 receives registration of conversion information from the LAN terminal 100 and records the conversion information in the storage medium 204. However, the conversion information may be recorded in advance on the storage medium 204 by the manufacturer or sales company of the router 200. In this case, the control device 203 may accept additional registration of conversion information from the intra-LAN terminal 100 and editing of the registered conversion information for conversion information recorded in advance.

  Alternatively, the control device 203 may acquire the conversion information from the information providing device connected to the wide area network via the WAN interface 201 and record the conversion information in the storage medium 204. In this case, the conversion information in the information providing device is always updated to the latest information, and the control device 203 determines whether the information providing device has the latest information periodically or based on a user instruction. When the inquiry and the latest information exist, the latest information may be acquired and the conversion information in the storage medium 204 may be updated.

  Further, the following recording method may be adopted for the conversion information. For example, when the control device 203 detects that a website is accessed from the LAN terminal 100, the control device 203 determines whether there is a convertible URL in the access destination URL. For example, when the access destination URL is the URL of a shopping site and there is a transit site for the shopping site, the information providing apparatus accessible via the storage medium 204 or the WAN interface 201 is connected in advance to each shopping site. For each URL of the site, the URL designated when going through the transit site is recorded as a convertible URL. The control device 203 refers to this information and determines whether there is information related to the access destination URL specified by the LAN terminal 100, thereby determining the access destination URL specified by the LAN terminal 100. It is determined whether there is a convertible URL for.

  As a result, when the control device 203 determines that there is a convertible URL in the access destination URL specified by the LAN terminal 100, the access destination URL specified by the user on the screen of the LAN terminal 100 is displayed. And a message notifying that conversion information in which the conversion URL that can be converted can be recorded in the storage medium 204 is displayed. As a result, when the user of the LAN terminal 100 makes a response indicating that the conversion information is desired to be recorded, the control device 203 records the conversion information in which the access destination URL is associated with the conversion URL in the storage medium 204. To do. Accordingly, the control device 203 can prompt the user to register conversion information when there is a URL that can be converted into the URL of the website accessed by the user.

(3) In the above-described embodiment, as illustrated in FIG. 3, the conversion information is an example in which one conversion URL 3b is associated with one access URL 3a. However, the conversion information may allow a plurality of conversion URLs to be associated with one access destination URL. In this case, when a plurality of conversion URLs 3b are associated with the access destination URL 3a, the control device 203 may select any one conversion URL 3b according to a preset selection criterion.

  For example, consider the case of going through a transit site in order to obtain the credit card points described above. In this case, a plurality of credit card companies may provide transit sites for one shopping site. When the user has a plurality of credit cards and there is a transit site for each credit card, the user needs to select any one transit site. In such a case, conversion URLs corresponding to transit sites corresponding to a plurality of credit cards possessed by the user are associated in advance with the URL of one shopping site, For the access to the shopping site, if the control device 203 selects one of the conversion URLs from a plurality of conversion URLs associated with the access destination URL, the convenience of the user is further increased. Can be improved.

  In this case, as a method for the control device 203 to select one conversion URL from a plurality of conversion URLs associated with the access destination URL, for example, the following method can be considered.

  When a plurality of conversion URLs are associated with the access destination URL designated by the LAN terminal 100, the control device 203 displays a list of the plurality of conversion URLs on the screen of the LAN terminal 100. Then, the user may accept the designation of the conversion URL. In this case, the control device 203 selects the conversion URL designated by the user.

  In addition, when a plurality of conversion URLs are associated with the access destination URL specified by the LAN terminal 100, the control device 203 automatically converts the conversion URL according to a preset selection criterion. May be selected. This saves the user from having to select a transit site. As a selection criterion, the history information of the transit sites that the user has passed through in the past is recorded, and based on the history information, the conversion URL corresponding to the transit site that the user has most frequently visited is automatically selected. Alternatively, a conversion URL corresponding to a transit site from which more credit card points can be acquired may be automatically selected.

  Here, a process for automatically selecting a conversion URL corresponding to a transit site from which more credit card points can be acquired will be described. For example, in the storage medium 204, as shown in FIG. 5, a plurality of conversion URLs 3b are associated with one access source URL 3a, and the point magnification 5a that can be acquired when each conversion URL is selected is recorded. deep. The information of the point magnification 5 a may be registered by the user after confirming the latest point magnification, or the control device 203 receives the latest point from the information providing device connected to the wide area network via the WAN interface 201. The magnification information may be acquired and managed so that the latest information is always maintained.

  When a plurality of conversion URLs are associated with the access destination URL specified by the LAN terminal 100, the control device 203 selects the conversion URL with the highest point magnification 5a. For example, in the example shown in FIG. 5, “http://www.aa.co.jp/keiyu1” having a point magnification 5a of 10 is automatically selected from the five conversion URLs 3b. Thereby, the user of the terminal 100 in the LAN can access the target shopping site using the conversion URL corresponding to the transit site from which the most advantageous privilege can be acquired.

(4) In the above-described embodiment, it is assumed that the user accesses the shopping site via the transit site operated by the credit card company, and automatically even if the user does not access the transit site. The details of the processing have been described with respect to an example in which the URL is converted to the conversion URL on the router. However, this example is merely an example, and when the user browses a website on the LAN terminal 100, the router 200 changes the access destination URL specified by the LAN terminal 100 to a conversion URL different from the access destination URL. The present invention can also be applied to other uses that are required to be converted into the above.

(5) In the above-described embodiment, data of a program for executing URL conversion processing using conversion information is recorded in the storage medium 204 of the router 200. In this case, the data of the program for executing the URL conversion processing described above may be provided by being recorded on a medium such as a CD-ROM or DVD-ROM, or may be provided from an external device connected via the WAN interface 202. It may be provided by downloading from a server. As a result, an existing router that does not have the function of executing the URL conversion process can be operated as the router 200 in the above-described embodiment.

(6) In the above-described embodiment, the example in which the conversion information is recorded in the storage medium 204 included in the router 200 has been described. However, the storage medium 204 may be an external storage medium provided outside the router 200. For example, the conversion information is recorded on a storage medium such as a memory card that can be read via a memory card reader, a flash memory connected to a USB port, or an external recording device connected via a USB cable or communication line. The control device 203 may read the conversion information from these storage media and perform processing. In this case, the external recording device connected via the network cable is arranged on the local area network connected via the LAN interface 202 even if it is arranged on the wide area network connected via the WAN interface 201. May be.

(7) In the access destination conversion system 10 in the above-described embodiment, the router 200 is used as a network device that operates as an access destination conversion device. The router 200 includes a WAN interface 201 and a LAN interface 202. The router 200 connects to the local area network to which the intra-LAN terminal 100 as the access source terminal is connected via the LAN interface 202. An example of connecting to the Internet via the Internet has been described. However, the configuration of the access destination conversion system 10 is not limited to this.

  For example, as a network device that operates as an access destination conversion device, other devices that relay a network such as a bridge may be used instead of the router 200. In this case, the network device is an access source that accesses a website. A first network connection interface for connecting to the first network to which the terminal is connected; and a second network connection interface for connecting to the second network to be accessed by the access source terminal. The control device included in the network device may perform the URL conversion process described above. That is, the network device control apparatus is assumed to be accessed from the access source terminal recorded in the storage medium when the access source terminal accesses the website via the first network connection interface. The URL to be accessed may be converted into the conversion URL by referring to the conversion information in which the URL of the website to be converted and the conversion URL different from the URL are associated. Accordingly, the access source terminal can access the website via the second network connection interface using the converted URL.

  In the configuration example in the embodiment described above, the local area network to which the intra-LAN terminal 100 is connected corresponds to the first network to which the access source terminal is connected, and the LAN interface 202 is the first network. Corresponds to the network connection interface. A wide area network such as the Internet corresponds to the second network, and the WAN interface 201 corresponds to the second network connection interface.

(8) In the above-described embodiment, the conversion information is an example of URL conversion information in which a URL of a website that is assumed to be accessed from the LAN terminal 100 is associated with a conversion URL that is different from the URL. . However, the conversion information may be IP address conversion information in which an IP address of a website that is assumed to be accessed from the LAN terminal 100 is associated with a conversion IP address different from the IP address. Further, both URL conversion information and IP address conversion information may be recorded as conversion information. In this case, the control device 203 refers to the IP address conversion information recorded in the storage medium 204 when the LAN terminal 100 accesses the website designated by the IP address via the LAN interface 202. Thus, the access destination IP address may be converted into a conversion IP address. As a result, even when there is an access specifying the IP address of the access destination site from the terminal 100 in the LAN, the LAN terminal 100 is automatically converted on the router 200 as in the case where the URL is specified. The website can be accessed by the IP address for conversion.

  It should be noted that the conversion information registration method in the above-described embodiments and modifications is the same when IP address conversion information is used as the conversion information. Also, in the IP address conversion information, a plurality of IP addresses for conversion can be associated with one access destination IP address, and the control device 203 can access the IP address as in the case of the URL described above. If a plurality of translation IP addresses are associated with each other, any one of the translation IP addresses may be selected according to a preset selection criterion.

  Note that the present invention is not limited to the configurations in the above-described embodiments as long as the characteristic functions of the present invention are not impaired. Moreover, it is good also as a structure which combined the above-mentioned embodiment and a some modification.
