Here, the explanation will focus on the home X1, but the same applies to the other homes X2,. Further, it is assumed that the local IP address and the IP address include a subnet mask. Further, the gateway Z1 is in a power-on state, and the memory 31 has a LAN gateway local IP address, a WAN IP address, a default gateway IP address set as the IP address of the Internet service provider SP1, and a DNS server access. It is assumed that various information such as an IP address and a login screen to the learning support server has been stored. Further, it is assumed that URL information for browsing a homepage registered in a general WEB server (here, WEB server 41 is taken as an example) is initially set in the browser program of the information terminal c1.

(Registration work for devices excluded from Internet communication restrictions)
When the father A1 of the home X1 wants to exclude the information terminals a1 and b1 owned by the mother and the mother B1 from being restricted by the Internet communication and to restrict the information terminals c1 to e1 owned by the children C1 to E1, first of the information terminal a1 Turn on the power. Then, the CPU 22 of the information terminal a1 transmits a network connection setting information request (attached to the terminal MAC address of the information terminal a1 as a transmission source MAC address) from the communication I / F 25 to the gateway Z1 having a DHCP server function. The CPU 30 that has input the request via the LAN side communication I / F 32 of the gateway Z1 determines YES in step S30 of FIG. 8, executes the DHCP server function because the current request is network connection setting information, and executes the DHCP server function. A unique local IP address is assigned to the terminal MAC address and registered in the memory 31 together with the terminal MAC address and the terminal number of the LAN connection terminal 32a (step S31). The network connection setting information (the local IP address of the information terminal a1, the IP address of the default gateway, the IP address of the DNS server) is returned to the information terminal a1 (step S32). The CPU 22 of the information terminal a 1 that has received the network connection setting information via the communication I / F 25 registers it in the memory 23. Note that the IP address of the default gateway is the local IP address on the LAN side of the LAN side communication I / F 32.

  When father A1 launches a browser program on information terminal a1, inputs the local IP address of gateway Z1 in the URL input field and performs a login screen call operation, CPU 22 logs in to gateway Z1 via communication I / F 25. Call request (the terminal MAC address of the information terminal a1 as the source MAC address, the LAN side MAC address acquired by ARP as the destination MAC address, the local IP address of the information terminal a1 as the source IP address, and the LAN side local as the destination IP address IP address is attached). The CPU 30 of the gateway Z1 that has input the request from the communication I / F 32 on the LAN side returns an administrator login screen and displays it on the screen of the information terminal a1 (steps S33 and S34 in FIG. 8). When the login ID and password are input, the CPU 22 makes an administrator login request to the gateway Z1. Upon receiving the request, the CPU 30 returns a management screen, and the CPU 22 of the information terminal a1 displays it on the display unit 21 (steps S35 and S36, see FIG. 12 (1)).

The management screen includes menu buttons 101 to 104 for selecting menus of <Network connection setting>, <Register / delete excluded terminal>, <Register user information>, and <Edit user information>. . The <Network connection setting> menu is used to set the WAN IP address associated with the communication I / F 33, the default gateway IP address (IP address of the Internet service provider SP1), the DNS server IP address, and the like. Although it is a menu, it is well known and will not be described.
When the menu button 102 of <registration / deletion of excluded terminal> on the management screen is pressed, the CPU 22 requests the gateway Z1 for registration / deletion menu of the excluded terminal, and the CPU 30 of the gateway Z1 returns an exclusion terminal registration / deletion screen. Since the information is displayed on the information terminal a1 (steps S37, S38, S39, FIG. 12 (2)), the input window 60A and 60B are input with the name of the terminal and the terminal MAC address as the terminal identification information of the information terminal a1. Then, the name of the mother who is the owner of the information terminal b1 and the terminal MAC address are input in pairs in the input windows 61A and 61B. If the father also has an information terminal a1 ′ different from the information terminal a1 and wants to exclude this information terminal a1 ′, the terminal MAC address of the information terminal a1 ′ is added to the input window 60C. If the mother also has an information terminal b1 ′ that is different from the information terminal b1, and this information terminal b1 ′ is also to be excluded, the terminal MAC address of the information terminal b1 ′ is entered in the input window 61C. Add and enter. When the registration button 62 is pressed to complete the input operation, the CPU 22 transmits the input content to the gateway Z1, and the CPU 30 registers it as excluded terminal information in the excluded terminal information storage area 31A of the memory 31 (steps S40 and S41, see FIG. 4). .
If it is desired to delete an already registered exclusion terminal, the list of registered exclusion terminals is also displayed on the registration / deletion screen of the exclusion terminal. Therefore, among the deletion buttons 63 to 65, the desired owner name to be deleted , Press the one corresponding to the terminal MAC address. Then, the CPU 22 requests the gateway Z1 to delete the excluded terminal information to be deleted via the communication I / F 25, and the CPU 30 of the gateway Z1 that has received the request from the excluded terminal information storage area 31A of the memory 31 as the deletion target. The selected excluded terminal information is deleted (steps S40 and S41).

(Registration of user information for Internet communication restrictions)
When registering the child C1 as a user who restricts Internet communication, the user presses the <Register User Information> menu button 103 on the management screen displayed on the display unit 21 or the registration / deletion screen of the excluded terminal. The CPU 22 requests a registration menu for user information from the gateway Z1, and the CPU 30 of the gateway Z1 returns a user information registration screen to be displayed on the screen of the information terminal a1 (step S37 or S46, S38, S39, FIG. 13). 1)). In the input windows 70, 71, 73 to 75 of this screen, the name of the child C1, the terminal MAC address as identification information of the information terminal c1, the user ID and password for accessing the learning support server 50, and the date of birth are input. To do. If the child C1 also has an information terminal c1 ′ different from the information terminal c1, the terminal MAC address of the information terminal c1 ′ may be added to the input window 72 and input.
In addition, the subjects that the child C1 wants to learn by selectively checking the check boxes 76 to 80 are input, and for each of these subjects, any one of the check boxes 76a to 76c, any one of 77a to 77c. ... Check any one of 80a to 80c and input the learning difficulty level for each subject.

In addition, the learning evaluation reference information for evaluating the learning contents in three ranks A, B, and C, and the correspondence relationship between the learning evaluation and the resetting time width of the allowable communication time range are also input.
As the learning evaluation reference information, a reference value based on the average score of the small test is input. That is, the average score of small tests is 10 points, A rank is 10 points or less and F points or more (however, 10> F), B rank is lower than F point and higher than G point (where F> G), C F and G when the rank is lower than G point and higher than 0 point are input to 81 and 82 of the input window. However, when the average score of the small test is 0, it is determined as unlearned as described later.

The correspondence relationship between the learning evaluation and the reset time width of the allowable communication time range is K when A rank is K time, B rank is L time, and C rank is M time (where K>L> M). L and M are input to the input windows 85 to 87. For the learning subjects and the level of learning difficulty, check the check box with reference to the lesson subjects and grades at the daily school of child C1.
When all the items have been input and the registration button 88 is pressed to complete the input operation, the CPU 22 transmits the input content to the gateway Z1, and the CPU 30 of the gateway Z1 stores the user information for one person in the user information storage area 31B of the memory 31. Are additionally registered (steps S40 and S41, see FIG. 4). At this time, the current month and date are initially registered in the storage area of the allowable communication time range item.
In addition, user ID and password, date of birth, learning evaluation reference information of A, B, and C, learning subjects and learning difficulty level are transmitted as user information for one person to the learning support server 50 connected to the Internet network 40. And register it (step S41). Specifically, the destination IP address and the IP address of the learning support server 50 are sent from the WAN side communication I / F 33 to the Internet service provider SP1 indicated by the default gateway IP address via the ONU (not shown) and the access line 35. The transfer request for the registered user information is requested. The Internet service provider SP1 transfers the user information registration request to the learning support server 50 via the Internet network 40. The learning support server 50 additionally stores the user information registration request through the communication I / F 54 in the user management information storage area 53A of the hard disk 53 (steps S70 and S71 in FIG. 11, see FIG. 6).
The user information input operation is performed in the same manner for the other children D1 and E1.

If it is desired to edit the registration information for the registered user information, the <Edit User Information> menu button 104 is selected on the management screen, the excluded terminal registration / deletion screen, the user information registration screen, or the like. The CPU 22 first requests the user information list from the gateway Z1, and the CPU 30 of the gateway Z1 returns the registered user information list and displays it on the screen of the information terminal a1 (steps S37, S46, S38, S42, FIG. 13). (See (2)). For example, when the father A1 wants to edit the registration information of the child C1, among the selection buttons 91, 92,..., The selection button corresponding to the name and user ID of the child C1 is pressed. The CPU 22 requests the gateway Z1 for the user information of the child C1, and the CPU 30 of the gateway Z1 returns the user information of the child C1 registered in the memory 31 to display the editing screen on the information terminal a1 (step S43, S44, see FIG.
In this editing screen, the father A1 has a correspondence relationship between the terminal MAC address of the child C1, the learning subject and the learning difficulty, the learning evaluation reference information of A, B, and C, the learning evaluation, and the resetting time width of the allowable communication time range. Of these, after editing a desired item, the edit button 94 may be pressed. The CPU 22 transmits an edit request including edit information to the gateway Z1, and the CPU 30 changes the user information of the child C1 registered in the memory 31 with the edit information (steps S40 and S41). Also, a user information change request is transmitted to the learning support server 50 connected to the Internet network 40 regarding the user ID and password, learning evaluation reference information, learning subject and learning difficulty level of the child C1 (step S41). The learning support server 50 changes the user information stored in the user management information storage area 53A of the hard disk 53 in association with the user ID when the CPU 51 receives the user information change request via the communication I / F 54. (Steps S70 and S71).
When all the registrations are completed, when the father A1 presses the logout button 90 on the screen and completes the operation, the CPU 22 transmits a logout request to the gateway Z1, and the CPU 30 performs logout processing (YES in step S45).

(Children's Internet communication restrictions)
For example, when the child C1 turns on the power to view a desired homepage stored in any of the general WEB servers 41, 42,... At the information terminal c1, the CPU 22 of the information terminal c1 is the same as in the case of the father described above. Then, an internet connection setting request is made, and the internet connection setting information notified from the gateway Z1 is registered in the memory 23 (step S10 in FIG. 7 and steps S30 to S32 in FIG. 8).

  When the child C1 starts up the browser program on the information terminal c1, the CPU 22 refers to the URL information of the homepage of the WEB site registered in the general web server 41 that is initialized, and requests an IP address inquiry corresponding to the domain name. (The terminal MAC address of the information terminal c1 as the source MAC address, the LAN side MAC address acquired by ARP as the destination MAC address, the local IP address of the information terminal c1 as the source IP address, and the DNS server IP address as the destination IP address) Including) is transmitted to the gateway Z1 (steps S11 and S12 in FIG. 7). When the CPU 30 of the gateway Z1 receives the IP address inquiry request, it activates the interrupt control processing of FIGS. 9 and 10, and since this request is an IP address inquiry request, the WAN side communication I / F 33, the ONU (not shown), and the access line 35 are connected. The Internet service provider SP1 is requested to transfer an IP address inquiry request to a DNS server (not shown). The Internet service provider SP1 transfers the IP address inquiry request to the DNS server via the Internet network 40, and returns the IP address returned from the DNS server to the gateway Z1. The CPU 30 of the gateway Z1 that has received the IP address from the WAN side communication I / F 33 returns the information to the information terminal c1 from the LAN side communication I / F 32 (steps S50 and S51 in FIG. 9).

The CPU 22 that has input an IP address via the communication I / F 25 uses this IP address as the destination IP address and requests access to the desired WEB server 41 using its own terminal MAC address as the source MAC address (in this case, homepage browsing) The request is transmitted to the gateway Z1 via the communication I / F 25 (step S12 in FIG. 7). When the CPU 30 of the gateway Z1 receives an access request to the Internet network 40 from the information terminal c1 via the LAN side communication I / F 32, the CPU 30 activates the interrupt control process of FIGS. 9 and 10 and checks the destination IP address. It is determined whether it is destined for the learning support server (steps S52 and S53 in FIG. 9). Since it is NO, it is subsequently determined whether it is destined for a general WEB server (step S60 in FIG. 10). Since YES, the terminal MAC address of the information terminal c1 is registered as excluded terminal information with reference to the registration information in the memory 31, and the Internet communication condition is unconditionally permitted, or is registered as user information and is constant. It is discriminated whether the permission is permitted only under the conditions or not registered and not permitted (step S61). Since the terminal MAC address of the information terminal c1 is registered in association with the user ID of the child C1 in the user information and is a conditional permission, the current date and time is registered in association with the user ID of the child C1. It is determined whether it is within the allowable communication time range (step S62).
If it is within the allowable communication time range, communication is permitted (step S63), and the CPU 30 makes an access request to the WEB server 41 through the WAN side communication I / F 33, the ONU (not shown), and the access line 35 by routing processing. The data is transmitted to the Internet service provider SP1, and a transfer request to the WEB server 41 is requested. Then, the home page data returned from the WEB server 41 via the Internet network 40 and the Internet service provider SP1 is returned from the LAN side communication I / F 32 to the information terminal c1, thereby enabling browsing of the initially set home page ( Step S65). However, since it becomes impossible here in step S63, CPU30 prohibits Internet communication and returns the login screen of the learning support server 50 to the information terminal c1 (step S64). URL information for login is attached to the login screen of the learning support server 50.

(Transition to the learning screen)
When receiving the login screen of the learning support server 50 from the gateway Z1, the CPU 22 of the information terminal c1 displays it on the display unit 21 (step S13 in FIG. 7). From the display, it can be seen that the child C1 cannot access a general WEB server such as browsing a desired homepage without learning. When the child C1 inputs his / her user ID and password and presses the login button to perform a login operation, the CPU 22 first refers to the login URL information and transmits an IP address inquiry request corresponding to the domain name to the gateway Z1. The CPU 30 of the gateway Z1 transfers the IP address inquiry request to the DNS server of the Internet network 40 in the same manner as described above, and returns the returned IP address to the information terminal c1. The CPU 22 of the information terminal c1 uses the received IP address as the transmission destination IP address, and transmits a login request including the user ID and password to the gateway Z1 (steps S14 and S15). Since the request destination is the learning support server 50, the CPU 30 of the gateway Z1 permits communication and performs relay processing (steps S52, S53, and S54 in FIG. 9). That is, a request for forwarding the login request to the learning support server 50 is sent to the Internet service provider SP1 via the WAN side communication I / F 33, the ONU (not shown), and the access line 35. The Internet service provider SP1 transfers the login request to the learning support server 50 via the Internet network 40.

  In the learning support server 50, the CPU 51 that has input a login request including the user ID and password via the communication I / F 54 searches for a match in the user information registered in the user management information storage area 53 A of the hard disk 53. Referring to the date of birth, learning subject, learning difficulty level, and learning history registered corresponding to the user ID, the grade, subject, and difficulty level of the learning material information meet the conditions, and 5 One unit is extracted, teaching material information for five frames is created, and it is sent back to the information terminal c1 (steps S72 and S73 in FIG. 11). The educational material information is relayed by the Internet network 40, the Internet service provider SP1, and the gateway Z1, received by the information terminal c1, and displayed on the display unit 21 by the CPU 22 (steps S54 and S55 in FIG. 9, and step S16 in FIG. 7). 15 (1)). The learning material information is attached with URL information for answer transmission and a user ID. Here, for convenience of explanation, it is assumed that the teaching material information includes five frames in one page, and the first frame portion is displayed first.

(Learning)
The child C1 proceeds with the learning by reading the explanation of the first unit displayed and answering the quiz. In the case of FIG. 15A, the answer is made by checking any one of the check boxes 95 to 97. When learning a plurality of frames, when the next frame button 98 is pressed, the CPU 22 scrolls up the screen to display the next frame portion. You can learn up to 5 frames. When it is desired to end the learning, the end button 99 is pressed. First, the CPU 22 refers to the URL information for answer transmission attached to the teaching material information, transmits an IP address inquiry request corresponding to the domain name to the gateway Z1, and learns this time using the returned IP address as the destination IP address. The answer of the small test (with user ID) is transmitted to the gateway Z1. Since the destination of the gateway Z1 is the learning support server 50, the CPU 30 permits communication and performs relay processing (steps S17 and S18 in FIG. 7 and steps S52, S53, and S54 in FIG. 9).
In the learning support server 50, the CPU 51 that has input the answer via the communication I / F 54 refers to the learning material information, scores a small test, and obtains an average score (steps S74 and S75 in FIG. 11). If the quiz is unanswered or if all questions are incorrect and the average score is 0, the CPU 51 determines that it has not been learned, and changes the quiz to the teaching material information for the frames for the five units this time. It is recreated and sent back to the information terminal c1 (steps S76 and S77). Here, if the average score of the small test is not 0, it is determined that the learning has been correctly completed, and the learning evaluation is performed by comparing with the learning evaluation standard registered corresponding to the user ID. Specifically, learning evaluation is performed by determining whether the average score of the small test is any rank of A, B, and C in comparison with the boundary value of the evaluation rank. Then, the learning evaluation information including the learning evaluation, the average score, the number of learning frames, and the reviews is returned to the information terminal c1 including a command for requesting resetting the allowable communication time range (step S78). Further, the current learning content (learning subject, learning unit, etc.) is additionally stored in the learning history corresponding to the user ID along with the learning date (step S79). The request for resetting the allowable communication time range is gateway Z1, which is registered as a default gateway IP address in information terminal c1.

(Permit Internet communication)
The learning evaluation information is relayed by the Internet network 40, the Internet service provider SP1, and the gateway Z1 and received by the information terminal c1, and is displayed on the display unit 21 by the CPU 22 (Steps S54 and S55 in FIG. 9, Step S19 in FIG. 7, S20 (see FIG. 15 (2)). The child C1 can see the displayed evaluation information as a next encouragement. After the learning evaluation information is displayed, the CPU 22 of the information terminal c1 outputs a reset request for the allowable communication time range including the learning evaluation to the gateway Z1 indicated by the default gateway IP address based on a command to make a reset request ( Step S21). The CPU 30 of the gateway Z1 refers to the correspondence between the learning evaluation and the reset time width of the allowable communication time range in the user information corresponding to the transmission source MAC address attached to the reset request, and sets the allowable communication time range Is reset to the month and date after the reset time width (steps S56 and S57 in FIG. 9). Thereby, the information terminal c1 is permitted to communicate with the Internet for the reset time width. For example, if the learning evaluation is A rank, the resetting time width corresponding to the A rank of the child C1 is 2 hours, and the current date and time is 18:30 on December 3, 20 December 20 Since the hour and 30 minutes are set, the child C1 can perform Internet communication for only 2 hours thereafter.
Instead of the CPU 22 automatically making a reset request, a reset button may be displayed on the learning evaluation screen and executed when the child C1 presses the reset button.
However, when it is determined that the learning support server 50 has not yet learned and the learning material for re-learning is received by the information terminal c1, the CPU 22 displays the learning screen again (steps S20 and S16).

(Internet communication)
When the child C1 presses the initial setting homepage browsing button 100 on the learning evaluation screen, the CPU 22 refers to the URL information of the initial setting homepage and transmits an IP address inquiry request corresponding to the domain name to the gateway Z1 (FIG. 7). Steps S22 and S23). Then, an access request (in this case, a homepage browsing request) to the desired WEB server 41 using the returned IP address as the transmission destination IP address and its own terminal MAC address as the transmission source MAC address via the communication I / F 25 is used as a gateway. It transmits to Z1 (steps S50 and S51 in FIG. 9 and step S23 in FIG. 7).

When the CPU 30 of the gateway Z1 receives an access request to the Internet network 40 from the information terminal c1 via the LAN side communication I / F 32, it checks the destination IP address to determine whether it is destined for the learning support server (step S52 in FIG. 9). , S53), since it is NO, it is subsequently determined whether the address is for a general WEB server (step S60 in FIG. 10). Since it is YES here, the terminal MAC address of the information terminal c1 is registered as excluded terminal information with reference to the registration information in the memory 31, and whether the Internet communication condition is unconditionally permitted or registered as user information. Whether it is permitted only under a certain condition or whether unregistered communication is not permitted is discriminated (step S61). Since the terminal MAC address of the information terminal c1 is registered in association with the user ID of the child C1 in the user information and is a conditional permission, the current date and time is registered in association with the user ID of the child C1. It is determined whether it is within the allowable communication time range (step S62). This time, the communication is permitted because it is within the allowable communication time range, and the CPU 30 sends an access request for the WEB server 41 to the Internet service provider SP1 via the WAN side communication I / F 33, the ONU (not shown), and the access line 35 by routing processing. Then, a transfer request to the WEB server 41 of the Internet network 40 is made. Then, the home page data returned from the WEB server 41 via the Internet network 40 and the Internet service provider SP1 is returned from the LAN side communication I / F 32 to the information terminal c1 (steps S63, S65, S66). The CPU 22 of the information terminal c1 displays the received home page (step S13 in FIG. 7). Thereby, the child C1 can browse a desired homepage.
If it is desired to browse another desired home page, the browser program may access the URL corresponding to the other desired home page.
However, when the current home date and time exceeds the allowable communication time range and the user accesses the desired home page, the CPU 30 of the gateway Z1 does not access the general WEB servers 41, 42,. Steps S60 to S64). Similarly, when the current date and time exceeds the allowable communication time range during the relay between the information terminal c1 and the general WEB servers 41, 42,..., The subsequent relay is prohibited (steps S65, S66, S67 in FIG. 10). , S64). In these cases, if the child C1 accesses the learning support server 50, logs in, and learns again, Internet communication becomes possible again.

(For other children)
When another child D1 (E1) turns on the power of the information terminal d1 (e1) and starts a browser program to browse a desired homepage, the current state at the time of access is the same as in the case of the information terminal c1. When the month and date have passed the allowable communication time range, the CPU 30 of the gateway Z1 does not access the general WEB servers 41, 42,. Thereafter, when the child D1 (E1) learns while receiving support from the learning support server 50 by the information terminal d1 (e1), thereafter, Internet communication is performed for the reset time width of the allowable communication time range according to the learning evaluation. It becomes possible.

(Unrestricted Internet communication)
When the father A1 (mother B1) launches a browser program on the information terminal a1 (b1) and performs an operation for browsing a desired homepage registered in, for example, the WEB server 42, the CPU 22 refers to the URL information of the desired homepage and refers to the domain name. An IP address inquiry request corresponding to is sent to the gateway Z1. Then, an access request (herein referred to as a homepage browsing request) to the WEB server 42 using the returned IP address as the transmission destination IP address and its own terminal MAC address as the transmission source MAC address via the communication I / F 25. The data is transmitted to the gateway Z1 (steps S50 and S51 in FIG. 9).

  When the CPU 30 of the gateway Z1 receives an access request to the Internet network 40 from the information terminal a1 (b1) via the LAN side communication I / F 32, it checks the destination IP address to determine whether it is addressed to the learning support server (FIG. 9). Steps S52 and S53), NO, so it is subsequently determined whether it is addressed to a general WEB server (Step S60 in FIG. 10). Since it is YES here, the terminal MAC address of the information terminal c1 is registered as excluded terminal information with reference to the registration information in the memory 31, and whether the Internet communication condition is unconditionally permitted or registered as user information. It is determined whether the permission is permitted only under certain conditions (step S61). Since the terminal MAC address of the information terminal a1 (b1) is registered as excluded terminal information and the Internet communication condition is unconditionally permitted, an access request to the desired WEB server 42 is not shown in the WAN side communication I / F 33 by routing processing. The data is transmitted to the Internet service provider SP1 via the ONU and the access line 35, and a transfer request to the WEB server 42 of the Internet network 40 is made. Then, the homepage data returned from the WEB server 42 via the Internet network 40 and the Internet service provider SP1 is returned from the communication I / F 32 to the information terminal a1 (b1) (steps S68 and S69). Since CPU22 of information terminal a1 (b1) displays on the display part 21, father A1 (mother B1) can browse a desired homepage without being restrict | limited at all.

In the home X1, at the maximum, the information terminals a1 to e1 possessed by the father A1, the mother B1, and the children C1 to E1 are simultaneously parallel to the general web servers 41, 42,..., Learning of the gateway Z1 and the Internet network 40. Communication with the support server 50 is possible.
In the same way as in the case of the above-mentioned home X1, the other home X2,... Excludes the Internet communication restriction to the gateway Z2,. By registering the terminal, user information for Internet communication restriction, etc., it is possible to perform time restriction when the children C2 and D2,... Communicate with the information terminals c2 and d2,.

According to this embodiment, while the children C1, D1,... Do not learn at the information terminals c1, d1,..., Even if they try to communicate with the general WEB servers 41, 42,. Prohibited by Z2, ... When the children C1, D1,... Learn with the information terminals c1, d1,... Being supported by the learning support server 50, the Internet communication can be performed within a limited time range. Therefore, it is possible to surely avoid learning from being overdone and to encourage children C1, D1,... To learn.
Moreover, since the learning of the children C1, D1,... Is evaluated and the time during which the Internet communication can be continued when the evaluation is good is made longer, the motivation for learning can be improved.
In addition, since the time range in which Internet communication is possible after learning can be set individually for each of the children C1, D1,..., The conditions according to the individual differences of the children C1, D1,. Can be limited.

In the embodiment described above, the case where the learning support server is provided on the Internet network side has been described as an example. However, the information terminal and the learning support server may be LAN-connected by providing on the LAN side of the gateway.
Further, the function of the learning support server may be integrated into the gateway.
Further, the gateway and the information terminal may be wirelessly connected.
Further, the gateway CPU determines whether or not the information terminal registered as the user information is communication with the learning support server from the transmission destination IP address when communicating with the Internet network. You may make it discriminate | determine whether it is communication with a learning assistance server from the domain name when inquiring an address.
Further, the learning evaluation is performed by comparing the average score of the small test with the reference value, but may be performed by comparing the total score of the small test with the reference value.
In addition, the learning evaluation is performed with three ranks A, B, and C, but may be performed with two ranks or four ranks or more.
