[0002]

2. Description of the Related Art For example, a connection to a so-called Internet, which is a collection of computer networks spanning almost the whole world, is usually made up of a regular IP line through a dedicated line.
Connection is a prerequisite, but participation at the individual level is practically difficult due to the high cost and expertise required to maintain dedicated lines and systems.

[0003] For this reason, dial-up IP connection, which makes an IP connection to a server of a communication carrier connected to the Internet via a public network such as a telephone line or ISDN when necessary, has become widespread.

[0004]

The address assigned to a user during a dial-up IP connection is as follows:
Users who use the Internet through a dial-up IP connection can not have a WWW server by themselves, and if there is information that they want to disclose, a homepage is stored in the server of the communication carrier to which they have contracted, because it is a transitional one. It is common to disclose indirect information by placing information resources such as the above and accessing the server of the communication carrier as necessary and updating the information resources regularly or irregularly.

[0005] For this reason, the amount of information resources that can be disclosed is restricted by contracts with telecommunications carriers, etc., and when the amount of information is large, the cost increases. When performing maintenance management, it is necessary to access the telecommunications carrier's server each time, and it is difficult to perform efficient maintenance management of information resources in real time. It was inconvenient when trying to make it public.

In order to realize a so-called mobile office or the like by utilizing the temporal and spatial freedom of connection through a dial-up IP connection to the Internet, access to public information of others on the Internet is difficult. Although it is easy, there is also a technical problem that another person cannot access the terminal itself, and the exchange of business information with the outside in the operation of the mobile office is actually restricted only by e-mail or the like.

[0007] It is an object of the present invention to provide a dial-up connection technology capable of improving the degree of freedom of information disclosure via an information network and reducing costs such as communication costs.

[0008] Another object of the present invention is to provide a dial-up connection technique capable of ensuring both freedom of connection to an information network and improvement of freedom of information disclosure via the information network. It is in.

Another object of the present invention is to provide a dial-up connection technique capable of improving the degree of freedom in exchanging business information with the outside in the operation of a mobile office.

Hereinafter, an example of the operation of the dial-up connection method in the information processing system according to the present embodiment will be described with reference to FIG.
This will be described with reference to flowcharts in FIG.

First, a general user (second user terminal)
For example, when an access occurs to the management source server 10 via the Internet 70 via the WWW interface (step S1), the WEB server 13d of the management source server 10 gives the access source user, for example, as shown in FIG. Response to the list of contents (step S
2), the access source user selects a desired content title (step S3).

At this time, if the selected content title is the member terminal 40 (first user terminal) to be dial-up connected, the WEB server 13d of the management source server 10 transmits a CGI (Common Gateway Interface) )), Using the member ID 27a as a key,
The member data information file 27 stored in the secondary storage device 26 of the member database 20 is accessed via the AN 30 to read the telephone number 27b of the member terminal 40, and the unused global information is read from the pool address data file 28. The address 28a is read out, and the dial-up server 13c sends the address 28a to the target member terminal 40 via the dial-up network I / F 51.
Dial-up I using global address 28a
P connection is attempted (step S4).

When the dial-up IP connection is successful (step S5), the member terminal 40 connects to the LAN 3
0, and then the WEB server 13d of the management source server 10 embeds the global address 28a as a URL as illustrated in FIG. 8A by means of CGI or the like. The generated link page is generated (step S6) and displayed in response to the access source user (step S7), and the access source user uses the global address 28a embedded in the link page to set the target member terminal. The access to 40 is started (step S8).

At the member terminal 40 receiving this access,
The WEB server 43d displays, for example, a content list as exemplified in FIG. 8B to the access source user (step S9), and the access source user obtains a desired information resource and the like. For example, in the example of FIG. 8B, from the personal mail-order properties registered in the content information file 47 of the secondary storage device 46 of the member terminal 40,
Carry out the contract procedure to purchase what you want.

Thereafter, when the access source user changes the access destination from the member terminal 40 to another member terminal 40 or another information resource on the Internet 70 (step S10), the management source server 10 executes line disconnection of the public network 50 in order to terminate the dial-up IP connection to the used member terminal 40 (step S11).

Here, in the case where the line disconnection in step S11 is performed from the management source server 10 side, it is notified that the access destination by the access source user has been changed from the member terminal 40 to another. Need to be notified. In the present embodiment, the following method is used as an example of the method.

That is, as exemplified in FIG. 9, in the HTML file 101 displayed at the access source from the member terminal 40 in the step S9, a pointer such as a URL indicating an information resource other than the member terminal 40 in advance. If the information 201 exists, the URL is replaced in advance with dummy pointer information 202 such as a dummy URL pointing to the dummy page 102 in the member terminal 40, and the item of the reference end menu is also included in the dummy page 102.
Is set in advance, such as dummy pointer information 202 such as a dummy URL pointing to.

In each dummy page 102, for example, a script or the like for generating an event for notifying the WEB server 43d that an access to the dummy page 102 has occurred is described. Information 201 is set.

In this way, if the access source user selects an information resource other than the member terminal 40 or terminates the access to the information resource of the member terminal 40, the WEB of the member terminal 40 is selected. Server 43d
Can detect this reference destination change event and notify the management source server 10 (step S12). Then, in response to this notification, the management source server 10 determines that the dial-up I
The line disconnection of the P connection can be executed.

As described above, according to the dial-up connection method of the present embodiment, the management server 10 initiates a dial-up to the member terminal 40 to be accessed upon an external access request to an arbitrary member terminal 40. After executing the IP connection and incorporating it into a part of the LAN 30 of the site to which the management source server 10 belongs, the access source can directly access the information resource of the member terminal 40 to which the target access request is made. .

Therefore, in each member terminal 40, the content information file 47 of the secondary storage device 46 in the own system is stored.
Arbitrarily can be constructed or maintained, and any information resource stored in the content information file 47 can be quickly disclosed by arbitrarily accessing it from the outside via the Internet 70 or the like. become. Therefore, as compared with a case where the information resource owned by the user of the member terminal 40 is placed in the management source server 10 and indirectly disclosed, for example, production, change, deletion,
And the like can be performed quickly and easily without requiring access to the management source server 10.

The member terminal 40 and the management server 10 are selectively connected by a dial-up IP connection only while the member terminal 40 accesses information resources. Communication costs and the like in the public network 50 can be significantly reduced as compared with the case of connection.

In the case of, for example, a mobile office, the business information (content information file 47) stored in the secondary storage device 46 of the member terminal 40 constituting the mobile office is externally transmitted via the Internet 70. Can be accessed arbitrarily from the Internet, and the availability and convenience of access via the Internet 70 for information held and managed by the member terminal 40 (mobile office) can be improved at a low cost by dial-up IP connection. it can.

When publishing data to a specific access source, for example, in step S9 described above, some kind of authentication process such as prompting for input of a registration ID, a password or the like is performed, so that data confidentiality is secured. Can maintain sex.

Next, a case where the member terminal 40 makes a dial-up IP connection to the management server 10 will be described with reference to FIG.

First, the dial-up client 43c of the member terminal 40 attempts a dial-up IP connection to the management server 10 via the dial-up network I / F 52 and the public network 50 by using a protocol such as PPP (FIG. 4). Step S20).

As a result, the dial-up server 13c of the management source server 10 sends the id,
A password input request is made (step S2).
1), dial-up client 43 of member terminal 40
c transmits an id and a password (step S22). Dial-up server 1 of management server 10
3c performs a predetermined authentication check on the input id and password (step S23), then disconnects the line once (step S24), and
From 0, an unused global address 28a is read from the pool address data file 28 of the member database 20, and a dial-up IP connection is attempted again to the original member terminal 40 at the global address 28a (step S25). When the dial-up IP connection from the management server 10 is completed (step S2).
6), the member terminal 40 is incorporated in a part of the LAN 30.

Then, an arbitrary general user (in the case of FIG. 2,
For example, when an access occurs from another member terminal 40) through a dial-up IP connection and the connection is established (step S27), the WEB server 13d of the management source server 10
Generates a link page in which the above-described global address 28a is embedded as illustrated in FIG. 8A (step S28) and transmits it to the access source (step S29).

The general user of the access source starts accessing the target member terminal 40 via the link page (global address 28a) (step S3).
0).

At the member terminal 40 receiving this access,
The WEB server 43d reads the content information file 4 stored in, for example, the secondary storage device 46 in its own system.
7 is edited into a desired HTML format and presented to the general user of the access source via the WWW interface (step S31), and an arbitrary information resource in the own system is provided to the general user of the access source.

The general user of the access source is the member terminal 40
When the access to the desired information resource in is completed, the line of the dial-up IP connection to the management source server 10 is disconnected (step S32). This triggers the management server 1
The 0 dial-up server 13c disconnects the line of the dial-up IP connection to the member terminal 40 (step S33).

Also in the case of FIG. 2, the member terminal 40 uses the means illustrated in FIG.
Earlier, when it is detected that the access destination has been changed from the access to the information resource of the member terminal 40 to the access to the information resource of another site other than the member terminal 40, The occurrence of the change is notified to the management server 10 (step S34), and the line of the dial-up IP connection to the member terminal 40 can be disconnected from the management server 10 (step S33).

As described above, in the dial-up connection method illustrated in FIG. 2, the exchange of information between the plurality of member terminals 40 connected by dial-up IP to the management source server 10 is performed by the two member terminals 40. By directly accessing the information resources inside, it can be realized at low cost.
