Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication service system for an apartment house, a router device, a communication service providing method for an apartment house, a computer-readable recording medium and a computer program, and more specifically, a resident of an apartment house. In contrast, the present invention relates to a communication service system of a housing complex that provides communication services such as connection to the Internet.

[0002]

2. Description of the Related Art In recent years, due to the spread of the Internet, homepages on which information such as products, news, weather forecasts, events, etc. are posted can be accessed from an information terminal such as a personal computer to allow users to access these websites at home. Products and information can be obtained. With the simplification of information acquisition and the increasing need for information on the Internet as described above, various service providers that provide Internet-related services provide various high-speed, safe and reliable communication services. Technology is being developed.

[0003] In particular, communication services provided to residents of collective housing such as condominiums are attracting attention because they increase the expectations and satisfaction of residents and increase the number of applicants. In such a communication service, a service user (user) resident of an apartment house inputs a user ID assigned to each user from an information terminal, whereby the service provider authenticates the user.
If this authentication process allows the user of the information terminal to be recognized as a legitimate user who can obtain such information, the user can obtain the desired information from any place, not only at home. Become.

[0004]

[Problems to be Solved by the Invention] Currently, although the broadband environment is being rapidly developed, not all residents need an advanced broadband environment, and those who can use only e-mail are enough. There are various needs for communication services, such as people who frequently surf the Internet and browse homepages frequently. However, in the service provision in the conventional housing complex described above, while benefiting from the lump sum purchase of the communication line by all the residents in the housing complex, the communication service of the frequency band or the transmission speed desired by each user can be provided at a low charge. It can be said that it is extremely difficult to use for the following reasons.

In order for a plurality of service provider subscribers (users) residing in one condominium to use services of different frequency bands or transmission rates, (1) lines with different frequency bands or transmission rates are drawn inside the building. Alternatively, (2) a method of separately preparing a band limiter for each user can be considered.

However, in the method (1), the resident has to bear a large amount of cost for the wiring laying work and the line purchase. Also, this wiring laying work is usually
In addition to the exclusive part of each resident, the scope of change extends to the common part, so it is necessary to make a decision on the assembly in order to establish the sectional ownership law.
Therefore, it can be said that this method is almost impossible due to the economic rationality and the complexity of the decision-making procedure based on the sectional ownership method.

On the other hand, in the method (2), an expensive band limiter has to be provided for each individual, and the occupant has a heavy economic burden.

Therefore, there is a problem that the use of the communication service according to the desire of the resident is high in cost and complicated preparation work is required no matter which method is adopted.

In order to deal with such a problem, there has been developed a technique of using a repeater such as a router to limit the band of a communication terminal connected to a network. In the technology related to this band limitation, the MAC (Media
Access Control) Bandwidth limitation based on address.

However, the MAC address is a hardware-dependent address. For this reason, when the resident of the housing complex changes the communication terminal, it is difficult to know that the new communication terminal is the property of the resident, and it is not possible to perform appropriate band limitation. there were.

In addition, when one upper line is shared by a plurality of residents such as an apartment house, it is an important subject to meet the request regarding the transmission speed. Although a cache server is used for this problem, there is a problem that the service provider needs to separately prepare a device for realizing this single function, which causes a cost increase.

[0012] In addition, in a personal service provided by a service provider, a DHCP server is generally installed on a network to dynamically assign an IP (Internet Protocol) address to each router or client. However, in such a dynamic IP address assignment, the address of the network changes for each connection session, and the whereabouts cannot be specified, so that there is a problem that it is not possible to manage whether the router device is functioning normally. .

Further, in the conventional communication service, when a failure occurs in the dial-up connection service or the like, the notification is S
It is usual to use a data communication part of a telephone line by NMP (Simple Network Management Protocol) or the like.
However, in reality, when the xDSL technology is used, there is a problem that the data communication part itself often fails. Further, there is a problem that there is no method for inexpensively notifying a failure occurring in the data communication part.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a communication service system for an apartment house, which can provide a desired communication service to a resident at a low charge. It is intended to provide a router device, a communication service providing method for a housing complex, a computer-readable recording medium, and a computer program.

Another object of the present invention is to provide a communication service system for a collective housing, a router device, a communication service providing method for a collective housing, and a computer-readable computer system capable of monitoring a network even if IP addresses are dynamically allocated To provide a recording medium and a computer program.

Next, the operation of the communication system for a housing complex realized by the communication system configured as described above will be described.

(1) Bandwidth limitation processing In the router device 108, the IP address automatic allocation module 302 classifies the IP addresses that can be allocated to the PC 112 into a plurality of groups by the VLAN technology. Specifically, the in-building LAN has a plurality of virtual networks (virtual LA
N), the maximum usable band of the frequency used for communication between the PC 112 and the Internet 100 is set for each virtual LAN. And
Assuming that each PC 112 is connected to the virtual LAN suitable for the connection environment desired by the resident, the PC 112 is divided into groups for each virtual LAN.

When a connection request to the Internet 100 is received from the PC 112, the IP address automatic allocation module 302 allocates an IP address in consideration of the virtual LAN. Routing module 3
In 06, based on the maximum use band of the group to which the IP address assigned to the PC 112 belongs, the PC 112
Limits the frequency band used for communication with the Internet 100.

As described above, by performing grouping based on the IP address dynamically assigned by the router device, frequency band limitation is performed without depending on the hardware address of the PC used by the resident of the condominium. be able to.

In addition to the above band limitation, the PC 1
By making the router device 108 recognize the twelve MAC addresses, it is possible to limit the bandwidth specifically for each resident.

(2) Cache Server Function FIG. 5 is a diagram showing the function of the cache server according to this embodiment. In this figure, LAN1 laid inside the building
A PC 112a and a PC 112b used by residents are connected to 09. When the PC 112a connects to the Internet 100, the router device 108 receives the packet from the PC 112a and sends it to the Internet 100. Next, when the router device 108 receives the packet sent from the Internet 100, the packet is delivered to the PC 112a and the packet is stored in the cache storage 312 by the function of the cache module 310.

As a result, when the PC 112b tries to obtain similar information, the cache module 210 uses the information stored in the cache storage 212 as the PC.
Since the data can be handed over to the PC 112b, the access from the PC 112b can be efficiently performed.

Further, for a site having a Web page that a user in the building frequently accesses, the Web page may be accessed in advance and stored in the cache storage 312 in advance. By pre-reading a specific Web page in this way, high-speed Web page display processing can be performed on the PC 112 in the building. The determination as to whether or not the site is frequently accessed by the user can be made by the log analysis process described later.

Further, using the cache server function,
A specific initial screen can always be displayed on the display of the PC 112 that has started the connection to the Internet 100. In this case, for example, in the center server 104, a web page of an initial screen for residents in the building is created. The router device periodically accesses the center server 104, acquires this Web page, and stores it in the initial data storage 330. Then, when the resident accesses the Internet 100, first, the We of the initial screen stored in the initial data storage 330 is displayed.
The page b is displayed on the display of the user's PC 112.

By carrying out such processing, the service provider can surely provide the information specialized for the occupants in the specific building that constitutes the condominium.

(3) Log Analysis Process Next, the log analysis process performed by using the above-mentioned cache server function will be described.

The access log analysis module 316 uses the cache module 310 to store the log storage 314.
By referring to the access log stored in, the log is statistically analyzed, and the analysis result is summarized in report data. Here, the analysis of the access log may include, for example, a process of obtaining a user's Internet usage tendency for each building, a frequently used website, a usage time period, and the like.

With this, it is possible to grasp the tendency of the user to access the Internet 100 and use it for the market research for the Internet connection service by the service provider and various advertisers, or electronic commerce companies. For example, by utilizing the cache server function of the router device 108, an operation such as advertisement distribution or rewriting can be performed by a remote operation from the center server 104 on an empty channel of the communication line drawn into the building.

Further, a packet filter function for discarding illegal packets and VLAN technology may be combined to perform specific advertisement distribution or information provision for each group of in-building users. As a result, the service provider, the advertiser, etc. can perform high-value-added marketing.

Further, by analyzing the access log, it is possible to determine the Web page that the user frequently accesses, so that it is possible to prefetch the Web page described above.

Further, the traffic monitoring module 308
Based on the traffic monitoring result by the above, the prefetching process may be performed during a time period when the user has little access to the Internet. In this case, the access log analysis module 316 uses the report file 3
With reference to the traffic monitoring results stored in 20,
Determine the times when access is low. Then, when the access time is low, the access log analysis module 316 to the scheduling module 318
To request read-ahead processing. The scheduling module 318 responds to this request by prefetching the web page.

(4) The operator of the center server 104 at the remote management processing service provider transmits a report reference request to the desired router device 108 through the telephone line using the telephone number assigned to the router device 108. . In the router device 108 that receives this request, the Web server module 3
By executing step 22, a web page based on the report is created by referring to the report file 320, and this web page is sent out through the upper line. The center server 104 displays the Web page of the report based on the data received from the router device 108.

The transfer of the report from the router device 108 to the center server 104 is not limited to the Web page. For example, the center server 104 accesses the router device 108 by telnet, and the data stored in the router device 108 is accessed by ftp. It may be acquired.

When a failure occurs in the router device 108, the telephone number of the router device 108 is used,

This notification is sent to the telephone network 116 via the analog line modem 604 and sent to the monitoring terminal 118. The monitoring terminal 118 displays a message on its display unit in response to the received notification.

According to the processing described above, even when a failure occurs in the data band portion, the router device 108
It becomes possible to notify the failure by using the telephone number given to the user and the voice part of the upper connection line.

Further, since each router device itself is made to monitor a plurality of router devices and create a traffic report, which has been intensively performed by one server computer in the past, each router device itself determines the location of the failure. , It becomes possible to divide it into the Internet side.

Although the preferred embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this embodiment and can be implemented in various other modes.

For example, the present invention can be applied to a communication service using an optical fiber as a communication line. Currently, only the expensive optical fiber communication service that provides a fixed IP address is provided, but if a low-priced variable IP service comes out in the future, the present invention will be applied to residents of collective housing. On the other hand, high-speed communication service can be provided at low cost.

Further, by utilizing the packet filter function of the router device in the building, the information terminal used by the user is
It is possible to prevent harmful contents and the like from being browsed by grouping the MAC addresses by the LAN technology and designating the IP address or URL of the site that should not be browsed for each group. As a result, it becomes possible to avoid complications such as setting a browsing prohibited site that each resident individually responds to on the PC for harmful content added on the WWW server every day.

The router device may also be equipped with gateway type virus checker software for checking for viruses. Conventional anti-virus measures generally depend on the settings of the virus checker installed in the resident information terminal,
In the communication service system to which the present invention is applied, the data received by the in-building user always passes through a specific route. Therefore, by installing the gateway-type virus checker software there, it is possible to effectively protect against viruses.
